I Went To Work Wearing Only Body Paint


– Alright guys, what’s up? How’s it goin’?
Hey, what’s up? Hello, hello, alright anyway,
let’s get on with the video. I really wanna get more
Instagram followers so why don’t you guys follow me? That’s the whole video. It’s just a little vlog of me
asking you guys to follow me. No, for real, I really wanna
get more Instagram followers. Right now I have about
8,000 on my Instagram page Which may seem like a lot but compared to other
social media people who have millions and millions and
millions and millions and millions of followers, it really isn’t that much. So I’ve been doing some research and it seems like what’s really popular on Instagram right now is body painting. Which is basically just female models getting painted in clothes and
it looks like they’re dressed but they’re actually naked. So all I have to do is get one of these accounts to
use me as their model. I spent the next few
hours trying to contact every single body painting
Instagram page I could find. Guys, Jen the Body Painter, who get millions and millions of views on each one of her posts just
agreed to use me as her model. I am super excited to do this. I hope I get a bunch of
followers out of this. Let’s go. Hey, how’s it goin’? – Good, good, good. Is there anything I can
do to prepare for this? – Wax the whole body? Do it for the Instagram followers. So I’m heading downtown
to get a sugar wax. Sugaring’s supposed to hurt a
lot less than regular waxing. It’s just lemon, water, and what the (bleep)
was the last ingredient? – Oh sugar, there we go. (laughing) So it’s not hot, you’re
not gonna get burnt, and they pull in the direction
that your hair grows. I don’t know why I’m doing this. I got to the salon and
I was really nervous. So was the lady. I had a lot of chest hair and I asked her if maybe I could have a local
anesthetic or something. She gave me some baby powder. (groaning) Oh, man. (heavy metal music) (screaming) Hurt so bad I ended up passing out. When I woke up and looked down I realized I have a 13-year-old Bar Mitzvah bod. I took my hairless bod to go
buy some very little underwear because I can’t be naked in the shoot. I met Jen the Body Painter
and her whole family but before we started shooting, I wanted to learn a little bit
about how they got into this. It stemmed from like using
bodies to advertise things? – Pretty much ’cause when I got painted as a cheetah I got so much attention. – Is it very different
than regular painting? – Oh yeah because the person moves. So with like a canvas, you just
can just sit there for hours and play your music whatever,
feel really relaxed. – So how long does it take usually? – Captain America was
seven to eight hours. For you, right now what
we’re getting ready to do it’s gonna take us two and a half hours. – So you guys are like
a family who just… – Does really weird things together. So I would literally come home from school and as soon as I’d walk in the door, like our kitchen is in sight, so I would see like topless
girls just walking around. – My mom never painted
naked models in my house. It was just like my dad
walking around naked. Anyway, time for me to get naked. It was awkward because
I realized I’m at work. – What the (bleep) is happening right now? (laughing) We then had to take a bunch
of pictures for the thumbnail. Being an instagrammer isn’t easy. Then they gave me so pre-painted shorts, so they didn’t have to paint my, you know. Looked at their phone to
find pictures of clothes and started painting. (electronic music) She also had to paint
inside my belly button. That was a big no-no. (electronic music) Time for the big reveal. Oh dude! Holy (bleep)! Wow! Oh my god. Yo, it looks so good! Wow! If anybody watches Friends,
when Bruce Willis talks to himself and he’s like
“Who’s a sex machine?” I’m a sex machine right now. I said that and nobody laughed
so it made me uncomfortable. (laughing) This painting is insane. You did that on me while I
was like talking and laughing? – [Jen] Yeah. – How’s my butt look? – [Jen] Great.
– [Second artist] Amazing – [Jen] Never looked better. – It’s time to go out, see if people notice,
see what people think. BuzzFeed, get ready for Naked Eric. (acapella singing) At first people didn’t even notice. And when they did, they
didn’t know what it was. – Are those leggings?
– [Eric] Yeah! – Are they even pants or
are they just leggings? – That feels like your skin. Is it your skin? – [Eric] It’s my skin. – Wait. What the (bleep)? – Oh wait. Oh my god it’s paint. (laughing) – This is… (laughing) – I’m naked. (laughs) – It looked like a real shirt. I’m like that is a small, tiny shirt. Oh my god. (laughs) – Are you a little cold? It’s a bit nipplely in here. – You’re wearing underwear because… – No, no, no. My penis is taped to my leg. (laughing) No, no, no, I’m kidding. It’s not, I’m wearing underwear. – Oh thank god, thank god. – How would it be taped? To what? – It’s also blizzarding outside so maybe not the wisest
choice today but… – Not at all, I have to go outside – I cannot stop staring at your penis. I am so sorry Eric, I just can’t do it. – Look at my eyes, that’s who I am. – Now you know how I feel all the time. – So this was super fun. Most people had no idea. It took a lot of people
a long time to realize I was painted and once
they realized, they were so impressed with the paint job. So I think that’s the coolest
thing about this video was like how good these
guys are at what they do. Body painting truly is an art
form, it’s really impressive. Now I’m gonna head home, figure
out how to wash this off. Getting home sucked because
there was a blizzard outside and well, paint doesn’t
really keep you warm. (heavy metal music) My nipples are so hard right now. Showering was fun though, I
looked like a human bath bomb. It looked pretty cool. I’ve been in the shower for 45 minutes, and it’s still not coming off. And my whole shower is bleached black. So I just finished
editing, it’s been a week. And here’s the update: Jen
the body painter has posted my post, she tagged me in it. It currently has over 500,000 views. And my Instagram page (drum roll) I only got 100 followers. I waxed my whole body for 100 followers. I’ve been itchy all
week for 100 followers. Everyone just cared
about the body painters, and not about me. I’m not giving up, though. I’m gonna keep making these videos till I get a million followers. (soft jazz music)

Bitcoin: How Cryptocurrencies Work


Say there’s a coin that’s currently worth
hundreds of U.S. dollars, but it’s not made of gold, or platinum, or any precious metal. In fact, it’s not the kind of coin you can
hold in your hand or stick in a piggy bank. It’s a digital currency, which means it
only exists electronically. I’m talking about bitcoin. Bitcoin doesn’t work like most money. It isn’t attached to a state or government,
so it doesn’t have a central issuing authority or regulatory body. Basically, that means there’s no organization
deciding when to make more bitcoins, figuring out how many to produce, keeping track of
where they are, or investigating fraud. So how does bitcoin work as a currency, or
have any value at all? Well, bitcoin wouldn’t exist without a whole
network of people and a little thing called cryptography. In fact, it’s sometimes described as the
world’s first cryptocurrency. And here’s how it works. Bitcoin is a fully digital currency, and you
can exchange bitcoins between computers in a worldwide peer-to-peer network. The whole point of most peer-to-peer networks
is sharing stuff, like letting people make copies of super legal music or movies to download. If bitcoin is a digital currency, what’s
stopping you from making a bunch of counterfeit copies and becoming fabulously wealthy? Well, unlike a mp3 or a video file, a bitcoin
isn’t a string of data that can be duplicated. A bitcoin is actually an entry on a huge,
global ledger called the blockchain, for reasons we’ll get to in a minute. The blockchain records every bitcoin transaction
that has ever happened. And, as of late 2016, the complete ledger
is about 107 gigabytes of data. So when you send someone bitcoins, it’s
not like you’re sending them a bunch of files. Instead, you’re basically writing the exchange
down on that big ledger – something like, “Michael sends Hank 5 bitcoins.” Now, maybe you’re thinking, “But, wait. You said bitcoin doesn’t have a central
authority to keep track of everything!” Even though the blockchain is a central record,
there’s no official group of people who update the ledger and keep track of everybody’s
money like a bank does – it’s decentralized. In fact, anybody can volunteer to keep the
blockchain up to date with all the new transactions. And a ton of people do. It all works because there are lots of people
keeping track of the same thing, to make sure all transactions are accurate. Like, imagine you’re playing a game of poker
with some pals, but none of you have poker chips, and you left your cash at home. There’s no money on the table, so a few
of you get out some notebooks, and start writing down who bets how much, who wins, and who
loses. You don’t completely trust anyone else,
so everyone keeps their ledgers separately. And at the end of every hand, you all compare
what you’ve written down. That way, if someone makes a mistake, or tries
to cheat and snag some extra money for themselves, that discrepancy is caught. After a couple hands, you might fill up a
page of your notebook with notes about the money movement. You can think of each page as a “block of
transactions.” Eventually, your notebook will have pages
and pages of information – a chain of those blocks. Hence: blockchain. Now, if thousands of people are separately
maintaining the bitcoin blockchain, how are all the ledgers kept in sync? To stick with our poker analogy: think of
the entire bitcoin peer-to-peer network as a really huge poker table with millions of
people. Some are just exchanging money, but lots of
volunteers are keeping ledgers. So when you want to send or receive money,
you have to announce it to everyone at the table, so the people keeping track can update
their ledgers. So for every transaction, you’re announcing
a couple of things to the bitcoin network: your account number, the account number of
the person you’re sending bitcoins to, and how many bitcoins you want to send. And all of the users who are keeping copies
of the blockchain will add your transaction to the current block. Having a bunch of people keep track of transactions
seems like a pretty good security measure. But if all it takes to send bitcoins is a
couple of account numbers, that seems like it might be a security problem. It’s a huge problem with regular money – just
think about all the ways criminals try to steal other people’s credit card information. And with bitcoin, there’s no central bank
to notice anything weird going on to shut down fraud, like if it looked like suddenly
you spent your entire life savings on beef jerky. So what’s stopping Hank from pretending
he’s me and just sending himself all of my bitcoins? Bitcoins are kept pretty safe thanks to cryptography,
which is why it’s considered a cryptocurrency. Specifically, bitcoin stays secure because
of keys, which are basically chunks of information that can be used to make mathematical guarantees
about messages, like “hey, this is really from me!” When you create an account on the bitcoin
network, which you might have heard called a “wallet,” that account is linked to
two unique keys: a private key, and a public key. In this case, the private key can take some
data and basically mark it, also known as signing it, so that other people can verify
those signatures later if they want. So let’s say I want to send a message to
the network that says, “Michael sends 3 bitcoins to Olivia.” I sign that message using my private key,
which only I have access to, and nobody else can replicate. Then, I send that signed message out to the
bitcoin network, and everyone can use my public key to make sure my signature checks out. That way, everyone keeping track of all the
bitcoin trading knows to add my transaction to their copy of the blockchain. In other words, if the public key works, that’s
proof that the message was signed by my private key and is something I wanted to send. Unlike a handwritten signature, or a credit
card number, this proof of identity isn’t something that can be faked by a scam artist. The “who” part of each transaction is
obviously important, to make sure the right people are swapping bitcoins. But the “when” matters, as well. If you had a thousand dollars in your bank
account, for example, and tried to buy two things for a thousand dollars each, the bank
would honor the first purchase and deny the second one. If the bank didn’t do that, you’d be able
to spend the same money multiple times. Which … might sound awesome, but it’s
also terrible. A financial system can’t work like that,
because no one would get paid. So if I only have enough money to pay Olivia
or Hank, but I try to pay them both, there’s a check built into the bitcoin system. Both the bitcoin network and your wallet automatically
check your previous transactions to make sure you have enough bitcoins to send in the first
place. But there’s another problem that might happen
with timing: Because lots of people are keeping copies
of the blockchain all over the world, network delays mean that you won’t always receive
the transaction requests in the same order. So now you’ve got a bunch of people with
a bunch of slightly different blocks to pick from, but none of them are necessarily wrong. Okay, bitcoin. How do you solve that problem? Turns out, it’s by actually solving problems. Math problems. To add a block of transactions to the chain,
each person maintaining a ledger has to solve a special kind of math problem created by
a cryptographic hash function. A hash function is an algorithm that takes
an input of any size, and turns it into an output with a fixed size. For example, let’s say you had this string
of numbers as your input And our example hash function says to add
all of the numbers together. So, in this case, the output would be 10. What makes hash functions really good for
cryptography is that when you’re given an input, it’s really easy to find the output. But it’s really hard to take an output and
figure out the original input. Even in this super simple example, there are
lots of strings of numbers that add up to 10. The only way to figure out that the input
was ‘1-2-3-4’ is to just guess until you get it right. Now, the hash function that bitcoin uses is
called SHA256, which stands for Secure Hash Algorithm 256-bit. And it was originally developed by the United
States National Security Agency. Computers that were specifically designed
to solve SHA256 hash problems take, on average, about ten minutes to guess the solution to
each one. That means they’re churning through billions
and billions of guesses before they get it right. Whoever solves the hash first gets to add
the next block of transactions to the blockchain, which then generates a new math problem that
needs to be solved. If multiple people make blocks at roughly
the same time, then the network picks one to keep building upon, which becomes the longest,
and most trusted chain. And any transactions in those alternate branches
of the chain get put back into a pool to be added onto later blocks. These volunteers spend thousands of dollars
on special computers built to solve SHA256 problems, and run their electricity bills
up sky high to keep those machines running. But why? What do they get out of maintaining the blockchain? Is it just community service? Well, bitcoin actually has a built-in system
to reward them. Today, every time you win the race to add
a block to the blockchain, 12 and a half new bitcoins are created out of thin air, and
awarded to your account. In fact, you might know the bitcoin ledger-keepers
by another name: miners. That’s because keeping the blockchain updated
is like swinging a proverbial pickaxe at those hash problems, hoping to strike it rich. When bitcoins were first created in 2009,
they didn’t really have any perceived value. Tens of bitcoins would have been worth the
same as a bunch of pennies. As of November 10th, 2016, though, one bitcoin
is worth 708 US dollars. So 12 and a half bitcoins are worth 8,850
dollars. That’s a nice chunk of change! Every single bitcoin that exists was created
to reward a bitcoin miner. Besides the big payout when they add a new
block of transactions, miners are also essentially tipped a very small amount for each transaction
they add to the ledger. It’s also worth noting that every 210,000
blocks, the number of coins generated when a new block is added goes down by half. So what started as a reward of 50 bitcoins
decreased to 25, then 12 and a half. It’ll only be around 6 bitcoins in a couple
more years, and keep decreasing. Eventually, there will be so many transactions
in a block, that it’ll still be worthwhile for miners to mostly be paid in tips. According to current projections, the last
bitcoin – probably around the 21 millionth coin – will be mined in the year 2140. This decreasing number of bitcoins is actually
modelled off the rate at which things like gold are dug out of the earth. And the idea is that keeping the supply of
bitcoins limited will raise their value over time. So, is investing in bitcoin a good idea? Now that’s… not really a SciShow kind
of question. Bitcoin is still volatile, and experimental. A lot of people love it, and a lot of people
think it’s doomed to fail. We just think it’s an interesting idea,
and it makes us wonder what cryptography might do for us next. Thanks for watching this episode of SciShow,

Ex: Exponential Growth Function – Bacterial Growth


– A BACTERIA CULTURE
STARTING WITH 200 BACTERIA GROWS AT A RATE PROPORTIONAL
TO ITS SIZE. AFTER THREE HOURS,
THERE WILL BE 900 BACTERIA. THIS IS AN EXAMPLE
OF AN EXPONENTIAL GROWTH. THIS IS AN EXPONENTIAL
GROWTH MODEL. SO WE’LL BE USING THE FUNCTION
P OF T=P SUB 0 x E RAISED TO THE POWER OF KT
TO MODEL THIS SITUATION, WHERE P SUB 0 IS A STARTING
POPULATION, K IS THE EXPONENTIAL
GROWTH RATE, T IS THE TIME IN HOURS, AND P OF T WOULD BE THE
POPULATION AFTER T HOURS. WE FIRST WANT TO EXPRESS
THE POPULATION AFTER T HOURS AS A FUNCTION OF T. THEN WE WANT TO FIND THE
POPULATION AFTER SIX HOURS. THEN WE WANT TO KNOW WHEN THE
POPULATION WILL REACH 5,000. SO LETS START BY FINDING
THE EXPONENTIAL FUNCTION THAT WILL MODEL
THE BACTERIA POPULATION. WE’RE STARTING
WITH 200 BACTERIA, WHICH MEANS P SUB 0=200 AND THEN AFTER THREE HOURS
THERE WILL BE 900 BACTERIA. SO WHEN T=3 THE POPULATION,
OR P OF T, IS GOING TO BE EQUAL TO 900. WE’RE GOING TO SUB THESE VALUES
INTO OUR EXPONENTIAL FUNCTION AND THEN SOLVE FOR K,
THE EXPONENTIAL GROWTH RATE. SO WE WANT TO SOLVE THE EQUATION
900=200 x E RAISED TO THE POWER OF K x T, BUT T IS 3, SO WE HAVE E RAISED
TO THE POWER OF 3K. AND NOW TO SOLVE THIS
EXPONENTIAL FUNCTION WE’LL START BY ISOLATING
THE EXPONENTIAL PART, OR E RAISED TO THE POWER OF 3K, SO WE’LL DIVIDE BOTH SIDES
BY 200. THIS SIMPLIFIES TO 1. 900 DIVIDED BY 200 IS 4.5, SO WE HAVE 4.5=E RAISED
TO THE POWER OF 3K. AND NOW TO SOLVE FOR K WE’RE GOING TO TAKE
THE NATURAL LOG OF BOTH SIDES OF THE EQUATION. AFTER DOING THIS WE CAN APPLY
THE POWER PROPERTY OF LOGARITHMS AND MOVE THIS 3K TO THE FRONT
OF THE NATURAL LOG. SO NOW WE HAVE THE EQUATION NATURAL LOG 4.5=3K x NATURAL
LOG E. BUT REMEMBER NATURAL LOG
IS LOG BASE E. SO WE HAVE NATURAL LOG,
OR LOG BASE E OF E, AND SINCE E TO THE 1st POWER
IS EQUAL TO E– AND, AGAIN, REMEMBER
IN EXPONENTIAL FORM WE WORK OUR WAY
AROUND THE EQUAL SIGN. E TO THE 1st=E, THIS SIMPLIFIES TO 1 AND MULTIPLYING BY 1
DOESN’T CHANGE ANYTHING, SO WE JUST HAVE THE EQUATION
NATURAL LOG 4.5=3K. SO TO SOLVE FOR K
WE DIVIDE BOTH SIDES BY 3. THIS QUOTIENT WILL GIVE US
OUR EXPONENTIAL GROWTH RATE. SO NOW WE’LL GO
TO THE CALCULATOR. NATURAL LOG 4.5 DIVIDED BY 3. NOW, THE MORE DECIMAL PLACES
WE USE, THE MORE ACCURATE OUR ANSWER
IS GOING TO BE, SO WE’LL USE SIX DECIMAL PLACES. SO IT’S GOING TO BE
APPROXIMATELY 0.501359.   AND NOW THAT WE HAVE OUR
EXPONENTIAL GROWTH RATE, WE KNOW OUR EXPONENTIAL MODEL IS GOING TO BE P OF T=
THE INITIAL POPULATION OF 200 x E RAISED TO THE POWER OF KT. AND NOW WE KNOW THE VALUE OF K, SO IT’S GOING TO BE
0.501359 x T, WHERE T IS THE TIME IN HOURS. SO LET’S TAKE THIS FUNCTION
BACK TO THE PREVIOUS SCREEN AND ANSWER
THE NEXT TWO QUESTIONS. SO IF WE WANT TO KNOW
THE POPULATION AFTER SIX HOURS, WE WANT TO FIND P OF 6
OR SUBSTITUTE 6 FOR T. SO P OF 6 WOULD BE
THE POPULATION AFTER SIX HOURS, SO WE WOULD HAVE 200 x E RAISED
TO THE POWER OF 0.501359 x 6. SO NOW WE’LL GO BACK
TO THE CALCULATOR AND TYPE IN THE RIGHT SIDE
OF OUR FUNCTION. WE PRESS SECOND NATURAL LOG,
THAT BRINGS UP E RAISED TO THE POWER OF   AND THE EXPONENT IS OUR
EXPONENTIAL GROWTH RATE x 6. IF WE ROUND TO THE NEAREST
BACTERIA, THIS WOULD ROUND
TO 4,050 BACTERIA.   AND THEN FOR OUR LAST QUESTION
WE WANT TO KNOW WHEN THE POPULATION
IS GOING TO REACH 5,000. WELL, WE CAN TELL
FROM THE PREVIOUS QUESTION IT’S GOING TO BE MORE THEN
SIX HOURS. SO, ACTUALLY, IN THIS QUESTION THEY’RE GIVING US P OF T
FOR OUR FUNCTION, WE WANT TO SOLVE FOR T. SO WE WANT TO SOLVE THE EQUATION
5,000=200 x E RAISED TO THE POWER
OF 0.501359T. AND TO SOLVE THIS
EXPONENTIAL FUNCTION, WE’LL ISOLATE
THE EXPONENTIAL PART, SO WE’LL START
BY DIVIDING BY 200. SIMPLIFIES TO 1. 5,000 DIVIDED
BY 200=25.   WE’LL NOW TAKE THE NATURAL LOG
OF BOTH SIDES OF THE EQUATION AND THEN ON THE RIGHT SIDE WE’LL APPLY THE POWER PROPERTY
OF LOGARITHMS, SO WE’LL MOVE THIS EXPONENT
TO THE FRONT. SO NOW WE’LL HAVE NATURAL LOG 25
=0.501359T x NATURAL LOG E. BUT REMEMBER
NATURAL LOG E IS=1, SO MULTIPLYING BY 1 IS NOT GOING
TO CHANGE THE VALUE OF THIS, SO WE CAN SIMPLIFY THIS OUT. SO TO SOLVE FOR T
WE’LL DIVIDE BOTH SIDES BY THIS DECIMAL COEFFICIENT. NOTICE ON THE RIGHT SIDE
THIS SIMPLIFIES TO 1, SO WE JUST HAVE T AND THEN WE’LL GET A DECIMAL
APPROXIMATION FOR THIS QUOTIENT. SO WE HAVE NATURAL LOG 25
DIVIDED BY 0.501359. SO WE CAN SEE IT’S GOING TO BE
APPROXIMATELY, LET’S SAY, 6.42 HOURS.   AND THAT’S GOING TO DO IT
FOR THIS EXAMPLE. I HOPE YOU FOUND THIS HELPFUL.

Logistic Growth: Using Recursive Equations


– WELCOME TO A LESSON
ON LOGISTIC GROWTH USING RECURSIVE FORMULAS. IN THIS LESSON WE’LL DERIVE A RECURSIVE LOGISTIC GROWTH
EQUATION AND ALSO FIND POPULATION LEVELS
USING LOGISTIC GROWTH. IN OUR BASIC EXPONENTIAL
GROWTH SCENARIO WE HAD A RECURSIVE EQUATION IN THE FORM P SUB N=P SUB N
– 1 + R, THE GROWTH RATE EXPRESSED
AS A DECIMAL x P SUB N – 1. IN A CONFINED ENVIRONMENT,
HOWEVER, THE GROWTH RATE
MAY NOT REMAIN CONSTANT. IN A LAKE, FOR EXAMPLE, THERE IS SOME MAXIMUM
SUSTAINABLE POPULATION OF FISH, ALSO CALLED A CARRYING CAPACITY, WHERE THE CARRYING CAPACITY OR
MAXIMUM SUSTAINABLE POPULATION IS THE LARGEST POPULATION
THAT AN ENVIRONMENT CAN SUPPORT. CONSIDER A LAKE WITH A CARRYING
CAPACITY OF 10,000 FISH. THE GROWTH RATE MAY LOOK LIKE
THAT SHOWN IN THE GRAPH BELOW. NOTICE HOW WHEN THE POPULATION
IS 10,000 THE GROWTH RATE WOULD BE ZERO BECAUSE 10,000
IS THE CARRYING CAPACITY. HOWEVER, IF THE POPULATION
IS BELOW 10,000, NOTICE HOW THE GROWTH RATE
WOULD BE POSITIVE, AND THEREFORE THE POPULATION
WOULD BE INCREASING. IF THE POPULATION HAPPENED TO GO
BEYOND 10,000 NOTICE HOW THE GROWTH RATE
WOULD BE NEGATIVE, AND THEREFORE THE POPULATION
WOULD BE DECREASING. SO LOOKING AT THIS RECURSIVE
EQUATION HERE FOR EXPONENTIAL GROWTH, IF WE CAN FIND THE EQUATION
FOR THE GROWTH RATE WE COULD PERFORM A SUBSTITUTION
FOR THIS R HERE AND HAVE A RECURSIVE FORMULA
FOR LOGISTIC GROWTH. IF WE WANT TO FIND THE EQUATION
OF THIS LINE HERE, NOTICE HOW THE Y INTERCEPT
IS 0.05. AND IF YOU WANT TO FIND
THE SLOPE USING THESE TWO POINTS HERE, NOTICE HOW WE’D HAVE TO GO DOWN
0.05 UNITS AND RIGHT 10,000 UNITS. WHICH MEANS, THE SLOPE WOULD BE
-0.05 DIVIDED BY 10,000, AND THIS IS ALL WE NEED IN ORDER TO FIND THE EQUATION
FOR THE GROWTH RATE. USING THE SLOPE INTERCEPT FORM
OF THE LINE WHERE THE FORM Y=MX + B, WE COULD WRITE IT AS Y=B + MX
INSTEAD. SO IN OUR CASE WE’D HAVE
R=THE Y INTERCEPT, WHICH IS THE 0.05 + SLOPE, WHICH IS -0.05 DIVIDED
BY 10,000 x THE INPUT VARIABLE, WHICH IN THIS CASE WOULD BE P,
THE POPULATION. SO THIS IS THE EQUATION
FOR OUR GROWTH RATE. NOTICE HOW IF WE FACTOR OUT 0.05 WE COULD WRITE THIS
AS A PRODUCT. WE’D HAVE 0.05 x THE QUANTITY
1 – P DIVIDED BY 10,000. THIS IS WHAT WE’LL SUBSTITUTE
FOR R IN OUR RECURSIVE EQUATION. SO BY PERFORMING THIS
SUBSTITUTION, WHICH IS HERE, AND OUR RECURSIVE EQUATION, WE NOW HAVE A RECURSIVE FORMULA
FOR P SUB N. P SUB N=P SUB N – 1 +
THIS PRODUCT HERE x P SUB N – 1. THIS IS A RECURSIVE EQUATION
THAT MODELS LOGISTIC GROWTH. SO TO GENERALIZE THIS, THE POPULATION IS GROWING
IN A CONSTRAINED ENVIRONMENT WITH THE CARRYING CAPACITY K, AND ABSENT CONSTRAINT WOULD GROW
EXPONENTIALLY WITH THE GROWTH RATE R. THEN THE POPULATION BEHAVIOR
CAN BE DESCRIBED BY THE LOGISTIC GROWTH MODEL
GIVEN HERE, WHICH WE JUST DERIVED. AGAIN, K IS THE CARRYING
CAPACITY AND R IS THE GROWTH RATE
ABSENT CONSTRAINT. UNLIKE LINEAR
AND EXPONENTIAL GROWTH, LOGISTIC GROWTH BEHAVED
DIFFERENTLY IF THE POPULATIONS GROW STEADILY
THROUGHOUT THE YEAR OR IF THEY HAVE
ONE BREEDING TIME PER YEAR. THE RECURSIVE FORMULA PROVIDED
ABOVE MODELS GENERATIONAL GROWTH WHERE THERE IS ONE BREEDING TIME
PER YEAR, OR AT LEAST A FINDING NUMBER
OF BREEDING TIMES PER YEAR. SO GOING BACK
TO OUR FISH EXAMPLE, LET’S SAY 2,000 FISH INTRODUCED
TO A LAKE WITH A CARRYING CAPACITY
OF 10,000. ABSENT ANY RESTRICTIONS THE FISH POPULATION WOULD GROW
AT 5% PER YEAR. FIND THE POPULATION AFTER ONE,
TWO, AND THREE YEARS. SO LOOKING AT THE GIVEN
INFORMATION, THE STARTING POPULATION,
P SUB 0=2,000, THE CARRYING CAPACITY IS 10,000,
SO K IS 10,000. AND THE GROWTH RATE,
ABSENT RESTRICTIONS, IS 5%, AND THEREFORE R IS 5%, EXPRESSED
AS A DECIMAL WOULD BE 0.05. AND USING OUR RECURSIVE

Instagram Model’s Disgusting Deal EXPOSED and Why People Are Arguing About It


‘Sup you beautiful bastards, hope you’re having a fantastic Thursday Welcome back to the Phillip DeFranco show, and uhh before we jump into it You may notice we have two special guests here today Because I’m giving the team a bunch of holiday time off, last night was our company Christmas party and I may or may not be hungover But we’re gonna get through my poor decision making together; let’s do this And the first thing I wanna talk about today is a story around Instagram models. When it comes to Instagram models, especially these smaller, don’t have a large following yet Instagram models, people are often wondering, how are they in this amazing situation; Penhouse villas, private jets, yachts. And it’s very easy to assume, well, they’re probably putting part of a very rich person into their mouths, and/or other stuff maybe they’re doing it because of a cool trip, part of promotion because they wanna get bigger on Instagram or maybe they’re getting paid But if you just take a peek at people like Dan Bullsarian’s account that guy has just launched women’s careers because they were just there, Like the world might not know about Lindsay Paris if it wasn’t for Dan Well separately from that I learned today that there is a site called “Tag the Sponsor” that is dedicated to exposing Instagram models, And the nasty stuff they will do. Recently they had one of the biggest stories to blow up, And that was about model Alaina Gonzales. There were leaked DMs where Tag the Sponsor is acting like a multi-millionare in Dubai. He’s asking, you know, How much can I purchase? I want you to have sex with me, I want you to have a threesome, I want you to have a threesome with my thirteen year old virgin brother. Then it gets pretty raunchy, but he convinces her to make a video make a video saying like, what are you willing to do? Saying I need this video to show that there is consent. “Hi, my name is Ariana *unintelligible* Gonzales, and um I’m twenty six years old, I’m willing to come to Dubai to to *unintelligible alias name*, we are having unprotected sex and I will let Mr. Ali lick *unintelligible* off my feet I will also fuck his virgin brother who is thirteen years old and I will let him lick my pussy and fuck me anal So two things there, for one I am now going to call it “an-all” And two, not the best look in the world to be video taped saying that you’ll have sex with a thirteen year old- I wouldn’t even say that jokingly, out of fear that someone would take that out of context, that joke, and put it somewhere else. And this video isn’t shocking to me obviously this happens. The most shocking thing about this story this story is he was even able to find this girl. She only has 1500 followers How did- How? but I mention all of this because now there’s a debate online. Is it wrong that this video was released? That’s the question, people are saying this is essentially slut-shaming Other people are saying, well, it’s not slut shaming, it’s the exposing of someone who’s willing to commit a crime. This exposes prostitution and a deal being made to have sex with a minor. I’ve seen some people saying this is the same as To Catch A Predator. I pass this question off to you, do you think it is wrong, or it’s right that this video was released? What are your thoughts on it in general, I’d love to know? And from there I’d like to talk to you about some stuff I Love today in Today In Awesome Brought to you by squarespace.com/phil squarespace of course the fantastic place to go if you want a fantastic blog online store, or whatever squarespace lets you use their simple, intuitive process where you can create and arrange content and features with just the click of a mouse if you want to check it out and make the smart move like many from the nation already have go to squarespace.com/phil, start that free trial and if you like it use coupon code PHIL for 10 percent off your first purchase and the first bit of awesome, it’s for those people who love westworld as much as I do- the entire album of songs used in this season of westworld is now on Spotify They previously released 5 but now you have the full 34 tracks Then you got to see some new Breath of the Wild playthrough thanks to Jimmy Fallon, Nintendo hopped on the Tonight Show to show off Super Mario Run, and Zelda. Then we got a new video from *jibberish* I can’t- uhh. my tongue’s too fat, my brain’s too stupid right now. a fantastic channel which, oh, apparently I was unsubscribed to – resubscribed. Umm. *laughing* Wow. Put out a new video called “A new history for humanity- a human era” fantastic video, i’ve become a big fan of this channel it’s one of my favourite channels on youtube this year so I support their patreon, highly recommend it, fantastic videos. Then in awesome that’s less “head-y” unless you wanna make a sex pun Madonna was on carpool karaoke and it was actually good! then we got a brand new trailer for baywatch, which I’m gonna watch because the Rock’s in it, okay? The Rock’s my Beyonce. I wouldn’t go and harass someone on Instagram for him for an unjustified reason, but uhh I like him. and it doesn’t hurt that Alexandra Daddario’s in it. This might shock some of you, but for me that’s an upside. and remember if you wanna see the full version of everything I shared, the secret link of the day, anything at all, links as always are in the description down below. then in the first time in over 20 years the life expectancy for an American just dropped. keep in mind it was a very small drop, the reason it’s news is it’s the first drop in a long time but it went from 78.9 years to 78.8 years. Ok I knew they always said women live longer, but holy crap Average male 76.3 years, average female 81.2 also the death rate rose, in 2015 2.7 million Americans died and the breakdown of how they died is fascinating, 45 percent died from either cancer or heart disease. the death rate for cancer actually dropped while heart disease went up. unintentional injuries went up, that includes things like car accidents as well as overdosing. stroke went up, diabetes went up kidney disease went up, suicide went up death from Alzheimer’s disease really went up, although people believe that is because there is greater recording of it. not necessarily because there was a drastic change. and the point of this story is- well there’s not necessarily a point my hope is that this is just a blip for life expectancy and it continues to go up. and the death rate is going to continue to go up as there are just more and more people in this country also makes the drop in cancer amazing. and now a story involving a man who probably wouldn’t mind a lower life expectancy. reportedly this man, 37 year old Gassi Rahm he came home late one night, he was drunk he was trying to get a little sex from his wife she was not having it, she rejected it and he reportedly cut off his own penis in a fit of rage And Gassi, I gotta say dude, if this is true, I get it why would you wanna have sex with such a drama queen You don’t wanna have sex with me? guess I don’t need this well- calm down! maybe it’s just who I am but you didn’t marry a vending machine reportedly they have been married 18 years he said in an interview, which- he’s just he’s on the bed, it’s all so weird, but he said we haven’t had sex in 10 years ok, that sucks, but maybe like, get a divorce. i’ll just never understand this, I’ve never been so angry at someone else that I was like I need to hurt ME. By hurting ME, that will somehow change them. No! All you’ve done is given her an even better exuse to not take it. You dun goofed, Gassi, you played yourself! And now let’s talk about the shooting that happened at Hug High School in Reno. if you haven’t heard there were reportedly students having a fight when one took out and threatened with a knife. some reports said the boy started threatening people with the knife, that the campus police was there, he drew his gun he told the boy to drop the knife, he refused to do so, and then the officer shot him. the boy was taken to the hospital and as of recording this video, is in critical condition. since this happened the boy’s father has identified him as 14 year old Logan Clark the police officer’s identity has not been released and he has been put on paid administrative leave police reportedly have a video that they haven’t released to the public but there are several videos of this incident online the video I personally saw on live leak is of Logan Clark with a knife not only brandishing it which is what ive seen a lot of places reporting, but actually you can see him swipe with it. then at around 22 seconds in you hear a single gun shot which is him being shot, and since this story blew up more background has been given. reportedly Logan’s dad posted to Facebook “To idiots that think Logan was wrong, know he was being bulled, he is not the kind to back down” “He brought the knives because he knew he was going to be jumped and he was. The school knew and failed to act [sic]” so there was a story that he was being bullied so that’s why he brought a weapon there are also people getting angry at the officer who shot Logan because he just had a knife and that I have to say, it is horrible if this kid was being bullied and nobody was doing anything about it, But when you have a student with a giant knife, who has not just held it but has slashed, that student is a threat and that threat has to be stopped. and no doubt is this happening a symptom of a much larger problem, but that police officer had to do what he had to do and bullying is wrong but so is attempted assault or attempted murder I think if “he was mean to me” was a legal defense, we’d have far fewer people in prison now there are also people saying the school shares blame and is somewhat to blame with this child if they did not actually protect him and they knew he was being bullied. And so with most of this story is this isn’t just a news show, it’s a conversation I’d love to know your thoughts on it you think the school and alleged bullies are also at fault, or no, you think it comes down to a person who made a decision and then having to deal with the ramifications of it? I’d love to know your thoughts and where you’re coming from on it and that’s actually where I’m gonna end today’s show and remember if you liked this video, like what i do on this channel hit that like button, if you’re new here hit that subscribe button but that said of course as always my name’s Phillip DeFranco, you’ve just been filled in, I love your faces and I’ll see you tomorrow.

Theoretical physics: insider’s tricks


Physics is the simplest and most central of
all branches of human knowledge. I know that. You know that. Everybody knows that. And it’s true! Of all of the branches of
physics, the truly deepest and most fundamental of all is particle physics. Our current theory,
which is called the Standard Model, is based around this single equation you see here.
In principle, you could simply take it, throw some math skills at it and figure out the
answer to all of particle physics’ questions. But there’s actually a problem- and that
problem is that nobody knows how to solve the equation exactly. The equation is simply
too difficult. So that might make you wonder how it is that
scientists can claim that they know what they’re doing when they can’t even solve the equation
that is central to the theory. Something sounds kind of shady. And you’d be right to wonder about that.
However theoretical physicists are a clever bunch and they employ a mathematical trick
called perturbation theory. The basic idea is to replace the unsolvable equation with
one that is approximately correct. While the calculation won’t be perfect, it’ll be
pretty close; and, if you need a more accurate calculation, you employ a more accurate approximation. So that might sound a little dodgy and, I
admit, when I was a much younger student, I sort of rebelled at the idea. But let me
give you some examples that might make you feel better about this approach. So- let’s start with a familiar one. Suppose
I needed to know with some precision the shape of the Earth. Depending on just how precisely
you need to know it, you’ll get a different answer. So the simplest answer to the shape of the
Earth is that it’s a sphere. We’ve seen pictures of it from NASA and there’s no
doubt that this is a very good approximation. The Earth is basically a sphere with a radius
of 6,367 kilometers or about 3,884 miles. But suppose I needed to know that number quite
precisely- say to an accuracy of a kilometer or about half a mile. Well, under that fairly
precise requirement, one has to do a bit better than the whole “Earth is a sphere” approximation. Because the Earth is spinning with a speed
at the equator of about 1,670 km per hour or about 1,000 miles per hour for my American
audience, the Earth actually isn’t a perfect sphere. We can see how this works by this demo here.
When the object is stationary, it has a circular shape. However, once the object is spinning,
we see that the shape deforms. It gets wider across the equator and shorter across the
polls. The spinning creates centrifugal forces. Yes, yes- I know that centrifugal forces are
fictitious, and if my main point was rotation, I’d be a bit more careful here. But the
idea of centrifugal forces is useful in this situation, so we’ll just let that one slide. Well, the Earth is also spinning and this
actually causes the globe to distort. The diameter of the Earth across the equator is
actually larger than the diameter connecting the North and South poles. And the difference is pretty big. It turns
out that the distance from the center of the Earth to the poles is 6,357 kilometers, while
the distance from the center to the equator is 6,378 kilometers. If you talk about diameter
and not the radius, the Earth is 42 kilometers fatter than it is tall. That’s a difference
of about 25 miles. So that sounds big, but is it? Well, if you
think of it in terms of a percentage, this difference is only about 0.3% or about one
part in 300. So it’s actually just a tiny correction. Unless you need to know the shape
of the Earth to an accuracy of under a percent, calling it a sphere is just fine. And this
is a crucial point. Calling the Earth a sphere is a very good approximation and it works
for most purposes. And the story doesn’t end there. If you
need to know the shape of the Earth even more accurately, it turns out that the Antarctic
ice sheet squishes the bottom of the Earth. This and a few other effects causes the North
Pole to bulge upwards about 17 meters, and makes a bulge of 7 meters in the mid-southern
latitudes. This picture here exaggerates what is going on, but essentially the Earth is
a bit pear-shaped. Well, that’s okay, the planet is getting older and it happens to
the best of us. Notice that I said meters here when we were
talking about kilometers before. The changes in the Earth’s geometry that gives it a
tiny pear-like shape are about 1/1,000 of the equatorial bulge distortion, which was
already a small one-in-three-hundred distortion on the basic spherical shape of the Earth. And, of course, if you want to get even more
precise, there are smaller distortions still, not to mention issues of mountains, hills,
trees, buildings, et cetera. But none of these ever-smaller corrections
changes the fact that the idea that the Earth is a sphere is a really good approximation
for most situations. Each successive approximation is just a small perturbation on the overall
and dominant shape. For most purposes, the approximation of a sphere is good enough. So this gives you the basic idea of how scientists
perform particle physics calculations. But I want to show you how it’s done in a slightly
more mathematical way. If you’re truly allergic to math, I’m, well- I’m sorry. But this
is just kind of cool, so hang in there. It’s really not that hard. Suppose you wanted to do a calculation that
involved a sine wave. You’ve seen pictures like this, where a mathematical function squiggles
up and down- that’s a sine wave. Well it turns out that it can be hard to do
calculations with such a complicated function- but there are ways to approximate it. Now,
I’m going to show you an equation that is another way to write a sine wave. You’re
going to have to trust me that I did it right. But, you do trust me, don’t you? Of course
you do! We’re old friends. So- this equation looks positively yucky.
I mean, on the left hand side we have a nice compact sine function and on the other side
we have lots of terms- an x term, an x-cubed term, an x to the fifth term. But here is
the beauty of perturbation theory. Maybe you don’t need all of those terms. Maybe just
the first one will do or maybe the first and second. And, if you can use just one or two,
the whole calculation can be a lot easier. So let’s take a look and see how many terms
we might need. Well, let’s plot the sine wave and then zoom into near the place where
x=0. Then let’s compare the sine curve to just the first term in the series- the
x term. The first thing we see is that the two actually agree pretty well. So that’s
already looking good. However when we zoom out a bit, we see that
the first term doesn’t do so well. The x term and the sine wave diverge quite a bit. So what happens if we add the second term-
the x-cubed term? Well, we see that it improves things a lot. But it’s not perfect. If we
add the third term, the x to the fifth power term, we see that the approximation looks
even more like a sine wave. In fact, if we added more and more terms, it gets better
and better. So that’s the beauty of perturbation theory.
Sometimes you don’t have to solve the hard problem. Instead, you can take an approximate
equation and solve that. The result will be a good enough answer for many cases. And,
if you need more precision, you just make a more accurate approximation. Okay- so now that you’re an expert on what
perturbation theory is all about, we can talk in general terms about how it applies to particle
physics calculations. Basically, all we do is to take the complicated
equation we started out this video with and replace it by a simpler and approximate one.
And voila! Instant success. Now this topic has a lot of facets to it,
so I’ve broken the conversation up into several different videos. To understand the
whole thing, you’ll have to watch all of them. So let me suggest that you also watch
my video on Feynman diagrams. Then you can combine the knowledge that you learned here
with the Feynman diagram video and you’ll be ready to tackle particle physics theory.
And the video that ties this all together is the one on theoretical quantum electrodynamics. So, to recap, perturbation theory is a key
trick that lets you get a handle on particle physics calculations. And if you combine this
video with the Feynman diagram and the QED one, then you will be a particle expert.

OYO Rooms Business Model | Case Study | How OYO rooms earns? | Hindi


Subscribe Intellectual Indies, press the bell icon and never miss an update. Hello dosto, my name is Sahil Khanna and you are watching Intellectual Indies and today we are going to talk about OYO Rooms. Like i’ve told you that I love the business model of OYO rooms. I know this time it’s in loss But in long term, they are going to in profit. Because basic need of A business is fulfilled by them Let me tell you a story of a person Hitesh Aggarwal, he was travelling in whole india He saw that he was unable to find rooms with affordable price Low price rooms were not good Differences in facilities were there He thought of starting a business With an investment of 1 lakh He invested 1 lakh He has created an empire of 2900 crore. And this company started in 2013. How this business grow so fast? They do receive the investments Investments no doubt helps the business. But you should have a business model. They did one more thing right If you can not fight with your competition then acquire it There was this company called Zo rooms. And they were doing the same business, They bought it Now they are only company in india That’s how they get investment easily Now they are not in that loss as compared to flipkart Limited loss And this loss is decreasing day by day. They have more than 70k+ rooms And tied up with more than 8500 hotels. in more than 230+ cities. This is the recent data One more thing: Early check in They were the first company to do this Basically it was an advantage in early check in Those who don’t know about early check in It means If check in timing is 11am then i am allowed to come after 11 only. If i come before 11 then i have to pay for it But according to their rules, if we book early Then you will come before a specific timing Then you can Condition applied: That room should be free It is not possible if a person is already in that room. They’ll try to give you the room Let’s talk about their business model. Like They acquire hotel rooms. Acquire means You have a hotel, they’ll ask for a room then they’ll decorate them room accordingly They’ll pay the hotels monthly wise. Let’s say your room cost is 2000 And oyo team will decorate it accordingly And then hotel can set a price monthlywise. Because of discount, they give them in 800-900 For calculation let’s say 1000 What happened now If they book only for 15 days They can reach no profit no loss After reaching the 16th day, their profit margin starts. The investment they did in decoration That’s a one time cost Second is Their team tries to negotiate They basically ask hotels to pay for the decoration and stuff and offer profit margin Commission Commission roomwise And commission can be any amount. Now this commission can vary from 10% to 80% According to my sources. I can not tell his name You can see this news that the acquire zo rooms. This is the list of their investors. All the details of funding. In short , their business model is profitable Their loss margin is decreasing day by day. This is a good business model. Now you tell me in the comments below Whether this business according to you is good or not If you’ll check OYO rooms is for innovation They always try to bring something new. IF you want to survive in your business journey Then innovation is important. Best thing is 20year guy build this company. Now he is just 23-24. Means a guy younger than us is a millionaire. 3000crore worth business. Okay friends, video ends here. I hope you liked it If any doubts, do ask me in the comment section. Like share and do tell me What should be our next business model. I don’t keep target of likes but you can like. Bye Goodnight Goodmorning Goodafternoon whenever you are watching this video.
