World’s Lightest Solid!

From 1veritasium, 2veritasium, or sciencium. Aerogels are the world’s lightest (least dense) solids. They are also excellent thermal insulators and have been used in numerous Mars missions and the Stardust comet particle-return mission. The focus of this video is silica aerogels, though graphene aerogels are now technically the lightest. At one point Dr. Steven Jones…

My Video Went Viral. Here’s Why

From 1veritasium, 2veritasium, or sciencium. My hypothesis is that the algorithm, rather than viewer preference, drives views on the site. As the algorithm shifts, various YouTubers experience burnout (as what used to work no longer works) and right now click-through rate is the key metric. So clickable titles and thumbnails are the only way to…

Why Are 96,000,000 Black Balls on This Reservoir?

From 1veritasium, 2veritasium, or sciencium. I took a boat through 96 million black plastic balls on the Los Angeles reservoir to find out why they’re there.
