Dialogue: 0,0:02:36.53,0:02:39.04,Default,,0000,0000,0000,,So, let's take a look at some of my videos.
Dialogue: 0,0:02:39.04,0:02:41.15,Default,,0000,0000,0000,,Here are eight of them.
Dialogue: 0,0:02:41.15,0:02:42.92,Default,,0000,0000,0000,,But down here in the lower-right corner,

Dialogue: 0,0:03:00.91,0:03:02.83,Default,,0000,0000,0000,,And in that episode, I answer the question
Dialogue: 0,0:03:02.83,0:03:04.70,Default,,0000,0000,0000,,and I get a chance to explain
Dialogue: 0,0:03:04.70,0:03:07.16,Default,,0000,0000,0000,,what would normally be kind of dry topics:
Dialogue: 0,0:03:07.16,0:03:07.99,Default,,0000,0000,0000,,optics,
Dialogue: 0,0:03:07.99,0:03:10.38,Default,,0000,0000,0000,,diffuse versus specular reflection,
Dialogue: 0,0:03:10.38,0:03:11.20,Default,,0000,0000,0000,,how light works,
Dialogue: 0,0:03:11.20,0:03:12.54,Default,,0000,0000,0000,,how light works on the retina,
Dialogue: 0,0:03:12.54,0:03:14.29,Default,,0000,0000,0000,,and even the etymology of color terms
Dialogue: 0,0:03:14.29,0:03:17.01,Default,,0000,0000,0000,,like white and black.
Dialogue: 0,0:03:17.01,0:03:19.12,Default,,0000,0000,0000,,Okay, spoiler alert:
Dialogue: 0,0:03:19.12,0:03:21.45,Default,,0000,0000,0000,,mirrors are not clear,
Dialogue: 0,0:03:21.45,0:03:23.34,Default,,0000,0000,0000,,they are not silvery
Dialogue: 0,0:03:23.34,0:03:24.96,Default,,0000,0000,0000,,like they're often illustrated.
Dialogue: 0,0:03:24.96,0:03:26.21,Default,,0000,0000,0000,,Mirrors, technically speaking,
Dialogue: 0,0:03:26.21,0:03:29.33,Default,,0000,0000,0000,,are just a tiny, tiny, little bit
Dialogue: 0,0:03:29.33,0:03:30.73,Default,,0000,0000,0000,,green.
Dialogue: 0,0:03:30.73,0:03:31.64,Default,,0000,0000,0000,,You can demonstrate this
Dialogue: 0,0:03:31.64,0:03:33.19,Default,,0000,0000,0000,,by putting two mirrors next to each other,
Dialogue: 0,0:03:33.19,0:03:34.69,Default,,0000,0000,0000,,facing so they reflect back and forth
Dialogue: 0,0:03:34.69,0:03:35.100,Default,,0000,0000,0000,,and back and forth forever.
Dialogue: 0,0:03:35.100,0:03:37.77,Default,,0000,0000,0000,,Look down that infinite reflection
Dialogue: 0,0:03:37.77,0:03:39.13,Default,,0000,0000,0000,,and it will get dimmer
Dialogue: 0,0:03:39.13,0:03:42.87,Default,,0000,0000,0000,,because some light is lost or absorbed every time,
Dialogue: 0,0:03:42.87,0:03:46.02,Default,,0000,0000,0000,,but it will also become greener
Dialogue: 0,0:03:46.02,0:03:47.83,Default,,0000,0000,0000,,because green light,
Dialogue: 0,0:03:47.83,0:03:49.15,Default,,0000,0000,0000,,that is light of a wavelength
Dialogue: 0,0:03:49.15,0:03:50.88,Default,,0000,0000,0000,,that we perceive as green,
Dialogue: 0,0:03:50.88,0:03:54.24,Default,,0000,0000,0000,,is best reflected by most mirrors.
Dialogue: 0,0:03:54.24,0:03:56.39,Default,,0000,0000,0000,,Okay, so, how much does a video weigh?
Dialogue: 0,0:03:56.39,0:03:59.42,Default,,0000,0000,0000,,Well, when you stream a video onto your computer,
Dialogue: 0,0:03:59.42,0:04:01.58,Default,,0000,0000,0000,,that information is temporarily stored
Dialogue: 0,0:04:01.58,0:04:03.50,Default,,0000,0000,0000,,using electrons.
Dialogue: 0,0:04:03.50,0:04:06.68,Default,,0000,0000,0000,,And the number of electrons on your device
Dialogue: 0,0:04:06.68,0:04:08.95,Default,,0000,0000,0000,,won't actually increase or decrease.
Dialogue: 0,0:04:08.95,0:04:11.97,Default,,0000,0000,0000,,But it takes energy to store them in one place,
Dialogue: 0,0:04:11.97,0:04:12.44,Default,,0000,0000,0000,,and we know,
Dialogue: 0,0:04:12.44,0:04:14.53,Default,,0000,0000,0000,,thanks to our friend Albert Einstein,
Dialogue: 0,0:04:14.53,0:04:16.82,Default,,0000,0000,0000,,that energy and mass are related.
Dialogue: 0,0:04:16.82,0:04:18.39,Default,,0000,0000,0000,,Okay, so here's the thing:
Dialogue: 0,0:04:18.39,0:04:19.92,Default,,0000,0000,0000,,let's say you're watching a YouTube video
Dialogue: 0,0:04:19.92,0:04:23.11,Default,,0000,0000,0000,,at a really nice resolution, 720p.
Dialogue: 0,0:04:23.11,0:04:25.03,Default,,0000,0000,0000,,Assuming a typical bit rate,
Dialogue: 0,0:04:25.03,0:04:29.88,Default,,0000,0000,0000,,we can figure that a minute of YouTube video
Dialogue: 0,0:04:29.88,0:04:31.51,Default,,0000,0000,0000,,is going to need to involve
Dialogue: 0,0:04:31.51,0:04:36.74,Default,,0000,0000,0000,,about 10 million electrons on your device.
Dialogue: 0,0:04:37.45,0:04:39.50,Default,,0000,0000,0000,,Plugging all those electrons
Dialogue: 0,0:04:39.50,0:04:41.00,Default,,0000,0000,0000,,and the energy it takes to hold them
Dialogue: 0,0:04:41.00,0:04:42.46,Default,,0000,0000,0000,,in the correct place for you to see the video
Dialogue: 0,0:04:42.46,0:04:43.81,Default,,0000,0000,0000,,into that formula,
Dialogue: 0,0:04:43.81,0:04:45.38,Default,,0000,0000,0000,,we can figure out
Dialogue: 0,0:04:45.38,0:04:47.26,Default,,0000,0000,0000,,that one minute of YouTube video
Dialogue: 0,0:04:47.26,0:04:50.64,Default,,0000,0000,0000,,increases the mass of your computer
Dialogue: 0,0:04:50.64,0:04:55.61,Default,,0000,0000,0000,,by about 10 to the negative 19th grams.
Dialogue: 0,0:04:55.61,0:04:58.66,Default,,0000,0000,0000,,Written out, it looks like this.
Dialogue: 0,0:04:58.66,0:05:00.15,Default,,0000,0000,0000,,That's like nothing.
Dialogue: 0,0:05:00.15,0:05:02.50,Default,,0000,0000,0000,,That's, you could call that nothing
Dialogue: 0,0:05:02.50,0:05:03.85,Default,,0000,0000,0000,,and you wouldn't really get in trouble
Dialogue: 0,0:05:03.85,0:05:07.51,Default,,0000,0000,0000,,because the best scales we've ever invented
Dialogue: 0,0:05:07.51,0:05:08.79,Default,,0000,0000,0000,,that we could try to use
Dialogue: 0,0:05:08.79,0:05:10.58,Default,,0000,0000,0000,,to actually to detect that change
Dialogue: 0,0:05:10.58,0:05:13.38,Default,,0000,0000,0000,,are only accurate to 10 to the negative 9th grams.
Dialogue: 0,0:05:13.38,0:05:15.04,Default,,0000,0000,0000,,So, we can't measure it,
Dialogue: 0,0:05:15.04,0:05:16.84,Default,,0000,0000,0000,,but we can, like we just did,
Dialogue: 0,0:05:16.84,0:05:17.88,Default,,0000,0000,0000,,calculate it.
Dialogue: 0,0:05:17.88,0:05:18.85,Default,,0000,0000,0000,,And that's really cool
Dialogue: 0,0:05:18.85,0:05:20.30,Default,,0000,0000,0000,,because when I was a kid,
Dialogue: 0,0:05:20.30,0:05:25.33,Default,,0000,0000,0000,,my school had two shelves of science books.
Dialogue: 0,0:05:25.75,0:05:26.80,Default,,0000,0000,0000,,That was really cool,
Dialogue: 0,0:05:26.80,0:05:28.80,Default,,0000,0000,0000,,but I read all of them within, like, two grades,
Dialogue: 0,0:05:28.80,0:05:29.88,Default,,0000,0000,0000,,and it was hard to get more books
Dialogue: 0,0:05:29.88,0:05:31.55,Default,,0000,0000,0000,,because books are heavy
Dialogue: 0,0:05:31.55,0:05:33.05,Default,,0000,0000,0000,,and you need space for them
Dialogue: 0,0:05:33.05,0:05:34.47,Default,,0000,0000,0000,,and moving books around is a lot tougher
Dialogue: 0,0:05:34.47,0:05:35.88,Default,,0000,0000,0000,,than what we can do today.
Dialogue: 0,0:05:35.88,0:05:37.46,Default,,0000,0000,0000,,With numbers that small,
Dialogue: 0,0:05:37.46,0:05:39.96,Default,,0000,0000,0000,,I can fit thousands of books

Dialogue: 0,0:05:43.06,0:05:45.23,Default,,0000,0000,0000,,I can stream hours and hours
Dialogue: 0,0:05:45.23,0:05:47.28,Default,,0000,0000,0000,,and days and days of YouTube video
Dialogue: 0,0:05:47.28,0:05:51.71,Default,,0000,0000,0000,,without my computer ever getting measurably heavier.
Dialogue: 0,0:05:51.71,0:05:54.33,Default,,0000,0000,0000,,And as information becomes that light,
