America is the land of inaccurate, outdated, and totally worthless measuring systems. While the U.S.A is one of three countries to scoff at the metric systes (along with our dudes Liberia and Myanmar), we also use a little thing called Fahrenheit when measuring temperature.

The U.S.A and its associated territories is one of five countries to use Fahrenheit (along with our dudes the Bahamas, Belizem, the Caymen Islands, and Palau), but why do we use this outdated system and where did it come from?

This handy video from the YouTube channel Veritasium answers at least one of those questions. Turns out it has origins a lot like Batman. When a young scientist’s parents die suddenly, he goes on the run and becomes obsessed with cool science gadgets. From there, he starts fighting crime, and by crime, I mean inconvenient and inaccurate temperature scales. Anyway, it makes sense in the video.

It’s entertaining, interesting, and as always will make you smarter than anyone in the room.

It’s a rainy Saturday afternoon, and you can’t go outside to play. If you’re thinking “this day will never end,” then you’re in luck.

The Infinite Galaxy Puzzle is here, and you can do it until the end of time. Not only that, you can assemble this bad boy in any shape or direction you please. It’s a 133 laser-cut pieces of birch plywood just waiting to put together in anyway you choose. The possibilities are endless, so you have no excuse for being bored ever again.

According to Gizmodo, the puzzle is based on a “scientific curiosity called Klein bottle, which is an impossible 3D shape whose insides and outsides are mathematically identical, the intricate pieces that make up this infinite puzzle can be transferred to its opposite side by simply flipping them over.”

The puzzle costs $100 and can be picked up from Nervous System. There’s also a $50 version, which comes with 51 pieces and no image to assemble — it’s just free play.

We’ve heard a lot about how thin and powerful the new iPhone 7 is. We’ve also heard a lot about how waterproof it is. But one question remains: Is this thing Acid Proof?

Good question, which is why TechRax poured the world’s most corrosive acid on the world’s most popular cellphone to find out.

Taking several crystals of Fluoroantimonic Acid and dropping them on a working iPhone 7, TechRax tests if the phone can withstand the acid for a day. The acid begins to eat away at the casing but does little to destroy the phone's battery. so The host then adds some hydrogen peroxide and sulfuric acid. Things get fun from there.

The results and the strength of Apple’s phone are very surprising, especially considering that most people break their phones by dropping them in the toilet. The phone actually turns on in the end, but what the acid does to this thing physically is really cool.

south african scientist optimistic about hiv vaccine

If it often feels like that the bad guys won and the Empire’s strike back was the final one, keep in mind that good things still happen on our little blue marble.

Case in point: This HIV vaccine, which will be released on Wednesday, could be the “final nail n the coffin” for the virus. Set to enroll over 5,000 sexually active men and women between the ages of 18 and 35, the study will be the “largest and most advanced HIV clinical trial to take place in South Africa, where more than 1,000 people a day are infected with HIV,” according to TIME.

Doctors are very optimistic about the effectiveness of this vaccine, which was found to be 31.2 perfect effective at preventing the virus.

“If deployed alongside our current armory of proven HIV prevention tools, a safe and effective vaccine could be the final nail in the coffin for HIV,” said Anthony Fauci, director of the U.S. government’s National Institute of Allergy and Infectious Diseases (NIAID).

“If an HIV vaccine were found to work in South Africa, it could dramatically alter the course of the pandemic,” said Glenda Gray, South African Medical Research Council CEO.

TIME reports the success of South Africa’s treatment program:

South Africa has more than 6.8 million people living with HIV, but the country has had remarkable success in rolling out an HIV drug treatment program, which the government says is the largest in the world.

Life expectancy, which sank as the epidemic grew, has rebounded from 57.1 years in 2009 to 62.9 years in 2014.

Even in a world overrun by bad news, people are still doing good work.

Let’s just put this out there: Gravity is the worst.

You know why gravity’s the worst? Because it prevents us from really reaching our ping pong potential. Sure, we can bask in the glory that is Forrest Gump playing table tennis against a wall, but are we really doing something meaningful?

Chinese astronaut Chen Dong thinks we can do better. So when he was on a local TV show in China, he showed off just how far humanity could reach without dumb gravity holding us down. What do you think of that, Sir Isaac Newton?

Check out these gifs from Mashable and say that gravity's worth it:

Or check out the whole video from CCTV on China Daily.

Chen plays it by himself, but he still has some catching up to do with NASA’s Scott Kelly, who plays “water ping pong.” Still, they are both strikes against gravity, which stinks.

You hear it every year:

“Turkey makes me sleepy because I’m a wittle baby.”

You’re probably so sick of hearing that, and not just because you invited a giant talking baby to your Thanksgiving again, but also because it’s not necessarily true.

via GIPHY

Wired has taken umbrage with the idea that the tryptophan-heavy turkey is what causes the Thanksgiving tiredness. In fact, as they point out in this bite-sized video, it’s the whole meal that makes you tired.

From soup to nuts, or whatever Thanksgiving metaphor that works better for this article, the whole meal delivers a hardy mixture of tryptophan and carbs. Ugh, not them again. Basically you get tired because all the food you eat contains these chemicals and all the carbs in potatoes and stuffing you cram down your gullet on Turkey Day force your body to slow down and digest.

Check it out the video and be the smartest person at the table.

The island of Ta’u in American Samoa is about to see their energy bill slashed in half.

Apparently, in addition to acquiring SolarCity this week, Tesla decided to power a whole island on their micorgrid of solar energy panels and batteries. Now, the system provides almost 100 percent of the power the power needed for Ta’u’s 600 residents. Hey, Tesla: 

via GIPHY

According to The Verge, Tesla’s system boasts some pretty impressive stats, like solar panels that can run without the sun for a full three days on a single charge and can recharge in seven hours. Compared to the 109,500 gallons of diesel required to power the island before, this is a pretty big argument in favor of solar energy. Again, quit showing off, Elon Musk.

Wait, no, continue showing off.

Check out the video above and hope that Elon Musk decides to show off in your town soon.
