Destin of SmarterEveryDay says, “There are tons of things I had never considered about how difficult it is to fool your brain into thinking it’s touching something it’s not. I think the most important technical issue to overcome is timing. Much like how your brain can understand hearing someone’s voice AFTER seeing their lips move, but not the opposite… the lag time of the sense of touch is an important thing for your brain. Another thing I hand’t considered is the “rise time” that has to do with internal stresses in your fingers. If you conceptualize your fingers as water balloons around bones, you can understand how the internal pressure of your fingers rise the harder you press something. This type of information coupled with the “Sensory Homunculus” make for some incredibly fulfilling thought experiments. The temperature question is something I’m particularly interested in. Using a colder fluid to model a room temperature fluid because of the heat transfer equation is a fascinating area of scientific problem solving. If you think it through, everything about this boils down to differential equations. How much heat is leaking out of the hand, and at what rate, through what contact area?”

World’s Fastest Camera

Stay Updated shows us how a research group at LUND University in Sweden has developed a camera that can film at a rate equivalent to five trillion images per second, or events as short as 0.2 trillionths of a second. It can actually capture the speed of light.

Destin of SmarterEveryDay gets to play with the very latest in virtual reality.

YouTuber and all-around science geek Destin of SmarterEveryDay went to see Space X’s launch of the Falcon Heavy and recorded it in Binaural Audio Immersion. Headphones recommended.

Television in Slo-Motion

The Slow Mo Guys (just Gav in his living room this time) follow up on their How a Camera Works episode with televisions, showing us exactly how pixels work.

How to Record Slow Motion Audio

Spoiler Alert: you don’t. All the sounds you hear in slow motion videos are added later. Destin of SmarterEveryDay tells us why:

Deciphering Barcodes

Half as Interesting breaks it all down:

Destin of SmarterEveryDay went to the 23andMe labs to find out exactly what they do and how they do it:
