There is very little more frustrating than sitting at a stoplight and watching the light go from green to yellow to red without you moving much at all. You have probably thought about the million ways you could fix the problem while you were stuck at one of those very lights. But, if given a million years, you probably wouldn’t think of the diverging diamond. This strangely designed interchange is faster and safer than the standard interchange. 

It is hard to imagine that people actually believe that the earth is flat. Sometimes it seems like an elaborate prank pulled by internet trolls. But there are actually people who believe that the earth is flat. If you can’t wrap your mind around why anyone would believe the earth is flat, take a look at this video. It’s a whopping thirty-minute conversation with someone who truly believes that the earth is flat.

If you have missed the news lately, you might have missed the latest (massive) Facebook scandal. Essentially, a group called Cambridge Analytica gathered millions of peoples’ Facebook data and used that data to manipulate voting in the U.S. 2016 presidential election. While many people freak out about that, we all need to remember that this isn’t the first time that anti-democratic agents have manipulated votes. Actually, there’s a long history of voter manipulation.

David Lynch’s movies are famous for their surrealism. He uses strange images and actions, surreal music, and sometimes jumbled plot lines to convey his meaning. If you pay close attention, you notice that he has a strange relationship with language. In fact, David Lynch kind of hates language. He doesn’t like words, and he doesn’t like what happens to films when you put them into words. That’s why some of his most famous scenes involve creepy poetry about magicians and backward-talking little people.

No other form of transportation appears more in movies than cars. Heck, even in Wes Anderson’s classic film Darjeeling Limited––named after a train!––cars play an incredibly important role. Cars are like characters’ costumes. What a character drives tells you a lot about his or her personality. Sometimes cars foreshadow something about the character development, sometimes they track the character’s development.This video analyzes the role of cars in films, digging into some of the most interesting car roles. 

The movie “The King’s Speech” tells the story of Prince Albert, born with an intense stutter, learning to speak properly so that he can ascend the throne of the United Kingdom. Using that story as inspiration, this teacher used the methods from the movie to teach a student born with a stutter to overcome his problem. This video explains how the teacher did it, and how the teacher’s extra time and care enabled that student to pass his English class and graduate.

Wendy Suzuki had it all. She was a brilliant scientist, had a successful research project underway, but she had no life. So she went on a rafting trip and realized something else: she had no muscles. So she went to the gym. A lot. As she exercised more, she realized her memory was getting better––she was an expert in observing the brain, after all. So she decided to study exercise and see if that’s why her memory was improving. Spoiler alert: it was.

Video essays are some of the best, most entertaining things on YouTube. And the best part is, they’re educational! Actually, wait, are they educational? This video points out that some video essayists in particularly gussy up their videos with the veneer of fact, despite those videos actually being entirely opinion. While it may be true that those videos are very well presented and argue, we wonder whether it’s the fault of the essayists that they make a convincing argument or if its the fault of viewers unable to distinguish between fact and opinion.

When you think of hoarders, you probably think of that reality show in which people with mountains of crap (sometimes literal crap, ew) get an intervention. But hoarding is a much more complicated situation than that reality show will lead you to believe. Take a look at this SciShow Psych episode, whiche explains the history of diagnosing hoarding. Originally, it was thought to be related to Obsessive Compulsive Disorder, but psychologists have recently figured out that it is quite different. 

It’s about 5:30. You’ve had a long day at work and had to skip lunch. You just got done with an extra long, extra trafficky commute. You walk in the house and your spouse is taking forever to get ready to go out to eat. That’s when it happens––you lose your cool. Your hunger drives you to snap at your spouse and you’re left feeling guilty and still angry. What causes hanger? Well, it’s a complex mix of psychology and physiology.

Recently, the Russian postal service launched its first package-delivering drone. Nevermind the fact that it promptly flew into a wall and shattered into a thousand pieces (see video below), drones in other countries––especially in the United States’ private sector––are getting really, really smart. Autonomously smart, that is. And wise the increase in their AI power comes a proportionate increase in deadliness and chance for catastrophe. 

If you were on trial for your life, you wouldn’t want to end up in a revolving-door court akin to traffic court. You’d want the most serious, proper court you could find. Unfortunately, this is the exact situation that some immigrants find themselves in. Whatever your stance on immigration, the United States is a country of law, and this John Oliver segment exposes how the law is not being upheld in immigration court.
