The speed of light is pretty darned fast, but given just how far the Earth is away from the Sun, its light it doesn’t get here instantly. It’s Okay to Be Smart teaches us how it’s not just a simple math equation, but complex astrophysics that explain how sunlight is much older than you’d think.

You might think that robots are a 19th or 20th century invention, but the idea of a humanoid machine dates back way further. TED-Ed looks back to an ancient Greek myth that involved a giant automaton warrior built to defend an island kingdom. It was also the first story about a robot struggling with its humanity.
The Royal Ocean Film Society gathered snippets from animation experts that point out the importance of walking in cartoons. We can learn a lot about a character – even a live one – by their walk, and changing even one element of it can drastically change the character.
Computers are pretty capable these days. And while most problems boil down to a series of mathematical computations, Tom Scott points out that there are some kinds of abstract problems that even the smartest programmers with the most powerful supercomputers can’t figure out.
Art of Engineering explains how the tall construction cranes used to build skyscrapers are able to increase their own height. The process, known as “climbing” a tower crane requires precision and patience, and can be incredibly dangerous if not done properly.
Science fiction movies love to depict all sorts of nasty consequences of being sucked out into space. But what would really happen if you managed to slip out of your spaceship without a spacesuit on? The Infographics Show does their best to explain the unpleasant repercussions.
We may take the roof over our head for granted these days, but in the 18th century, families venturing into the interior of North America had to build their own shelters to survive the elements as they headed westward. Frontier lifestyle expert Jon Townsend shows us how they might have constructed a shelter without any nails.

(PG-13: Language) Here in America, shopping malls are a dying breed. But what happened to these symbols of capitalism that were once the gathering place for teens as they sipped on Orange Juliuses and perused the black light illuminated aisles of Spencer Gifts? Ordinary Things explores the demise of the mall.
(PG-13: Language) While they’re not the most fashionable things, face masks are a must in public places these days. Ordinary Things dives into the origins of face coverings, from the earliest ceremonial masks, to costumes, to their use as protective gear. Can you imagine walking around in those plague doctor masks?
Artificial intelligence is getting better at identifying objects in still images, and more recently in video. Now machine learning tech is getting smart enough to look at what’s happening in a video and answer questions about what it has seen. Two Minute Papers provides a brief overview of CLEVRER and its capabilities.
Humble teamed up with publisher Morgan & Claypool for this bundle of e-books which dive deep into the science, math, and technology of artificial intelligence and machine learning. Pay what you want, and the more you spend, the more e-books you get. A portion of every purchase goes to the Book Industry Charitable Foundation.
If you squint really hard, a hot dog kind of looks like a weiner dog on a bun. But is that really where this food got its name? Today I Found Out’s Simon Whistler digs into the etemology, history, and rather unappetizing composition of the ballpark and school lunch favorite.
If you’ve ever seen a beehive up close, you know how its made up of hundreds of nearly perfect hexagonal cells. Why is that, and how do bees know how to make such perfect geometry? TED-Ed provides a brief explanation of this strange intersection of evolutionary biology and architecture.
Science and technology vlogger Tom Scott created a YouTube video that automatically updates its own title based on its view count. As he explains in the video, he used YouTube’s programming APIs to pull off the trick, then talks about the wonders and downsides of open data interfaces.
It doesn’t matter if you’ve got the most expensive display you can buy, gradients of color in dark scenes often look like a blocky mess. Tom Scott offers a great explanation of the technological limitations that cause these issues, and the visual mechanisms that make them less noticeable in brighter scenes.
(PG-13: Language) With the COVID-19 pandemic upon us, people have been going crazy hoarding food and other supplies. But this certainly isn’t the first time panic buying has occurred. Ordinary Things looks back at times when fear overtook reason, and also attempts to explain why toilet paper is always the first thing to go.
Electrical engineer Mehdi Sadaghdar of ElectroBOOM presents a series of simple demonstrations involving magnets, batteries, and wires, each of which might seem magical, but can all be easily explained by science. He might have a goofy approach to teaching, but if you stick around, you might learn a thing or two.
Did you know that the smartphone in your pocket has moving parts inside of it? Devices such as accelerometers use a hybrid of mechanical and electronic mechanisms known as MEMS. New Mind puts this fascinating and complex tech under the microscope to explain how they work, and how they’re made.
The Art Assignment argues that whether it be something as primitive as bones or as advanced as a neural network, there’s always a human touch at the root of all machines used to make art. We like to think of it from the other end: art is unfinished until a human mind ponders it.
You’d think that you wouldn’t get rid of an airplane until it was beyond its useful life, but it turns out that some airlines dump their older jumbo jets because they’re just not cost effective to operate. Half as Interesting takes us on a one-way flight to Victorville, California to see where these flying behemoths are often retired.
What If explores the hypothetical question of what would happen if you were like Ant Man, and could shrink yourself down to whatever size you wanted. As you descend from the size of a frog’s egg to the size of an atom, would things be totally awesome down there, or absolutely horrifying?
