What color is a banana? Duh, it’s yellow. But what is yellow? Now that you mention it, how do we see color in the first place? That’s the series of questions that led me to making this video. It started simple and took me down a rabbit hole of decoding our visual system. Turns out it’s way more interesting than I ever thought possible. You might even call it complex. In fact, it’s a wonder it even works. Biology… wow, right?
Thanks to vision researcher Dr. Jay Neitz from the University of Washington for helping us break down this complex science.

8 min - Who Built the Metric System (and Why It Isn't As Perfect as You Think)Meter? …or Metre?Try CuriosityStream and learn something new today: http://curiositystream.com/smart↓ More info and sources below ↓Why is a meter a meter? The meter is the world’s ultimate measure, but how did it become “the” meter? What is this measurement based on? The story of this revolution in measurement traces its roots to the French Revolution. Scientists decided that an equal and united people should have equal and united measures. So they sent a pair of young astronomers out to measure the world, and invent the meter. Little did they know they’d find nothing but war, deception, and strife along the way. As a result of this ill-fated mission, the meter carries an error that still persists today. Still think the metric system is so perfect?Viewers like you help make PBS (Thank you 😃) .
