Why Cities?

Why Cities?

In which John discusses the agricultural revolution, the development of permanent settlements, and whether cities were good news. SOURCES BELOW. Hank is publishing a novel next year! https://www.nytimes.com/2017/09/19/books/youtube-star-hank-green-first-novel.html But before then, we are going on tour to celebrate my new novel, Turtles All the Way Down: http://www.turtlesallthewaydownbook.com/#tour SOURCES: Hunter-gatherers have less famine than agriculturalists: http://rsbl.royalsocietypublishing.org/content/10/1/20130853 This gets into some of the archeology and analysis of human remains that indicates that hunter-gatherers lived on average longer and healthier lives than agriculturalists. The Case against Civilization inspired this video and includes the statistics about how much hunter-gatherers work in food acquisition and domestic labor: https://www.newyorker.com/magazine/2017/09/18/the-case-against-civilization This article also explores some of the complexities of agriculture's development: http://www.npr.org/sections/thesalt/2016/07/15/485722228/where-did-agriculture-begin-oh-boy-its-complicated The book discussed in "The Case against Civilization" is called AGAINST THE GRAIN, and while I disagree with a lot that's in it, I also think it's an interesting read and outlines both its case for why cities developed and other people's cases. I also leaned on the book SAPIENS by Yuval Noah Harari for some of the theories about why cities developed. Our World in Data is an amazing resource for understanding long-term trends in human history. That's where I got the graph about the dramatic reduction in absolute poverty the world is experiencing: https://ourworldindata.org/extreme-poverty/ And also the graph about the declining number of hours worked: https://ourworldindata.org/working-hours/ And lastly, the median U.S. household income really is higher (even after adjusting for inflation) than it ever has been before: https://en.wikipedia.org/wiki/Household_income_in_the_United_States ---- Subscribe to our newsletter! http://nerdfighteria.com/newsletter/ And join the community at http://nerdfighteria.com http://effyeahnerdfighters.com Help transcribe videos - http://nerdfighteria.info John's twitter - http://twitter.com/johngreen John's tumblr - http://fishingboatproceeds.tumblr.com Hank's twitter - http://twitter.com/hankgreen Hank's tumblr - http://edwardspoonhands.tumblr.com Preorder John's new book, Turtles All the Way Down, out October 10th 2017!

We have put together a list of the most fantastic and unbelievable scientific facts that seem too crazy to be true. This world will never stop surprising us, just take a look for yourself! Scientists have recently found that the universe tastes like raspberries and the Mona Lisa actually used to have eyebrows. The coldest place in the Universe isn’t on the Moon, where temperatures can plunge down to minus 378°F. It was recorded in a lab, where scientists in Finland managed to freeze atoms using a laser. If we could get rid of the empty space in atoms, all of humanity would fit into an apple. The biggest living organism in the world is a mushroom. Human lungs have the same surface area as a tennis court. Whether a man has a son or a daughter can often depend on what kind of siblings he has. You might have heard that a person is usually a bit taller in the morning than they are in the evening. As for the height of the Eiffel Tower, it changes depending on the weather. The cavefish can walk and climb thanks to its tetrapod-like pelvis. It uses its flippers like four-legged land animals use their limbs. your brain helps you stay fit! Assuming that the average metabolic rate during rest periods is 1,300 calories, your brain takes 260 of them! Thumbnail: Cryptotora thamicola.

Sony's Clever but Flawed PlayStation Copy Protection--And How They Might Have Fixed It

Sony's Clever but Flawed PlayStation Copy Protection--And How They Might Have Fixed It

You can support this channel on Patreon! Link below The original PlayStation is a pretty neat thing. Using the CD as a storage medium was a smart move. But, Sony needed to add anti-piracy features to the disc to prevent miscreants from making bootleg copies of Crash Bandicoot. This video tells the story of how that works, why it wasn’t infallible, and also proposes a potentially impervious solution (24 years late, though). Here’s that paper on reading optical discs. It’s a good read: https://pdfs.semanticscholar.org/f772/6d20c43b22fb13f8788c8c64df2dbe9fa44f.pdf You can support this channel on Patreon! Patrons of the channel are what keep videos like this coming.

11 Survival Tips from a Former Secret Agent

11 Survival Tips from a Former Secret Agent

A former secret agent is sharing his advice on how to get through any critical situation. It's always fascinating to see how easily CIA agents in movies can survive any extreme situation. Well, they’re even cooler and more resilient in real life. So even if you're the safest driver ever, it wouldn’t hurt to know what to do in case of an accident. When you’re driving, you should keep your hands at 9-and-3, not 10-and-2 as they used to say. Unfortunately, dog attacks are also quite common these days. A mixture of water and ammonia, using a can of pressurized air, like those sprayable air dusters for cleaning keyboards or pepper spray or another animal’s urine will save you. If you ever find yourself in a burning building, there's a chance that you'll need to knock the door down to escape or help others. The way you see it done in the movies couldn't be more wrong! Running towards it and throwing your whole body against it can leave you with a dislocated shoulder or even broken bones. In the moment, panic often takes over, but try to suppress it and follow some important rules. To protect yourself during a shooting, you need to find a good cover. If you’ve got a gun pointed at you, it's best to behave extremely carefully to minimize any possible risks of getting seriously hurt. If a serious explosion is about to go off, your actions should be quick and precise. Finding refuge is the most important thing. In case you get locked in the trunk of a car, you can try to open the trunk's lock latch. Another option is to try to escape through the folding back seat. If the snow on the ground is really thick and you see a couple of evergreen trees nearby, then you’ve found the perfect place to build yourself a refuge to wait out the storm and warm up a bit. Music: Barge Gunnar Olsen Sci-Fi Swamp Chase - Sir Cubworth TIMESTAMPS A car crash 0:46 A dog attack 1:50 Knocking the door down in case of fire 2:50 Barricading a door 3:37 A shooting 4:23 Being at gunpoint 5:19 An explosion 6:12 Being locked in the trunk of a car 6:50 If your hands and feet are tied together 7:37 Being in water with your hands and feet tied 8:21 Making a shelter in deep snow 9:11 Bonus: secret agent must-haves 10:10 SUMMARY -When you’re driving, you should keep your hands at 9-and-3, not 10-and-2 as they used to say. If you’re a passenger in the back seat, during a collision, put your hands on the back of your head, press your forehead against the seat in front of you, and keep your knees bent at a 90° angle. -A mixture of water and ammonia is one of the best ways to scare away aggressive dogs. The most effective choice is pepper spray or another animal’s urine. -A precise and powerful enough kick with your heel will knock out any lock. -You can put rubber doorstops all around the door’s crevices or do it like in the movies: just put a bunch of heavy objects in front of the door. -To protect yourself during a shooting, you need to find a good cover. Remember that things like clipboards and hardcover books can stop bullets, so you can use them as a bulletproof vest. -If somebody is pointing a gun at your back and has ordered you to walk ahead, raise your arms and slow down so that the gun is pressed right up against your back. Then, turn around quickly, bring one arm down so that it traps the gun under your armpit, and use your other arm to attack the gunman. -Finding refuge is the most important thing. Cross your legs, open your mouth, and cover your ears with your hands. -Find the emergency pull located on the inside of the trunk, and the trunk will pop open. -To free your legs, stand up straight and point your toes out to make a “V” with your feet. Then, jump up and as you land, spread your knees really fast. If your hands are tied behind your back, you need to get them in front of you. Once that's done, press them together tightly and then quickly pull them apart. -Don't panic, take deep breaths in and quick breaths out. If you're swimming on your belly, move by bending your knees, straightening them back again, and keeping your back arched so that your head stays above water. -Find the thickest evergreen tree with low hanging branches and dig a hole in the snow along the tree trunk. Then pack the snow on the “walls” of your hideaway as densely as you can. -Some of the most popular contents in special agents' bags include a key to handcuffs, a flashlight, a gun, a pen, a compass, a razor blade, a pocket knife, a mouthguard, and some lockpicks.
