Mark Zuckerberg on Taking Risks and Finding Talented People

What we’re going to do in this video is talk about hypothesis testing, which is the heart of all of inferential statistics. Statistics that allow us to make inferences about the world. So, to give us the gist of this, let’s start with a tangible example. …

( intro music ) Mike Libecki: Sixty-five expeditions and counting and the goal is to do 100 expeditions by 100 years old. This is what I call the Polar Bear Fang. And I’ve been trying to this tower for ten years. For a climber, this is as good as it gets…

Let’s see if we can compute what 1.86 divided by 2 is. And like always, pause this video and have a go at it. I’ll give you a hint: see if you can think about 1.86 as a certain number of hundredths, and then divide that by 2. All right, now let’s work th…

In this video, we’re going to talk about analog versus digital. Something that’s analog can be any value within a given range, while something digital is represented by a number of discrete or separate levels. To distinguish these two ideas, I like to th…

Let r be the function given by r if theta is equal to three theta sine theta for theta is between zero and two pi, including zero and two pi. The graph of r in polar coordinates consists of two loops, as shown in the figure above. So let’s think about wh…

All right, we can now do the math to solve for v. So let me just simplify the right-hand side of this equation. v minus negative e? Well, that’s just going to be two v. One minus negative of v squared over c squared? Well, that’s just one plus positive v…
