Hey, Vsauce. Michael here and Derek.

00:06

78? That's so random. Or is it?

00:11

What does it mean to be random?

00:14

Can anything really be random? What's the most random thing ever?

00:18

Today let's stop being random and become 'ransmart'.

00:23

If something is unpredictable,

00:26

and contains no recognisable patterns, we call it random.

00:30

So let's begin our hunt for the most random thing with a coin toss.

00:35

The Australian 50 cent coin is one of the largest coins

00:39

currently in circulation.

00:42

Coin flips and rolling dice are not intrinsically random,

00:47

they are only random because of our

00:50

ignorance. If we could know every initial condition

00:54

the exact forces and properties that play for a particular flip or roll,

00:58

we could theoretically calculate the result before it

01:02

even happened. And, sure enough, researchers have built coin flipping robots

01:07

that can precisely control a flip to get the result they want

01:10

100 percent of the time.

01:14

So here is our question. Is there anything you couldn't predict

01:19

even if you knew everything? A process determined

01:23

by nothing? And how can you be sure they're

01:27

aren't any patterns in what you're looking at? Maybe you just haven't looked

01:30

for the right pattern yet.

01:31

Or maybe you have already seen true randomness

01:35

but didn't know it because you didn't look for long enough.

01:39

As if protected by a sort of camouflage,

01:42

a random process can, and will, occasionally produce patterns.

01:47

YouTube URLs are pretty much

01:50

random. A unique one is made for every uploaded video, but sometimes,

01:54

like the proverbial monkeys typing away on typewriters,

01:57

YouTube generates a URL that contains, by chance, a word.

02:02

The official music video for 50 Cent's

02:05

'In Da Club' contains a synonym for bottom.
