Calculating Pi with Darts

If you dove into the sun, the first layer you’d hit is hot enough to make diamonds BOIL. Right now we’re in a golden age of new solar science. For the first time, we’re getting close-up pictures of the Sun like we’ve never seen. Sending probes into its atmosphere. And revealing secrets about our star we never thought possible… Trust me, after this video, you’ll never look up at the sun the same way. So let me take you on a journey… INTO THE SUN.

How do you take copper wire, a battery and magnets and make electric train? With science! This super simple DIY physics demo uses electromagnetic induction to propel a train made of magnets and batteries.

What happens when you drop a perfectly balanced stack of balls? And how is the result like a supernova? The classic momentum transfer demonstration, taken to the next level. A big thank you to my nephews and niece Drew, Max and Whitney for creating the trampoline footage! Thank you to the Vlogbrothers for sponsoring this video, to Kyle Kitzmiller for filming, and to Island School on Kauai for providing the balls (ischool.org).

Pi can be calculated using a random sample of darts thrown at a square and circle target. The problem with this method lies in attempting to throw "randomly." We explored different ways to overcome our errors.

Protons and neutrons are made of three quarks, right? Wrong! Explore the particle they should have told you about when you were a kid!

What do programmers actually do?    

There are only certain parts of the year and certain times of day when you can experience the subsolar point or Lahaina noon. There appears to be no shadow because the sun is directly overhead. This phenomenon happens twice a year for latitudes between the tropic of cancer and the tropic of capricorn at solar noon, when the sun is highest in the sky. But you have to be in the right place at the right time with no clouds! The photos and clips in this video were taken by my mom, Cathy, and friend Noel Liddell in Wailua, Po’ipu and Lawai, HI on July 11th (one day before exact Lahaina noon) and July 12th.
