I am a scriptwriter for the popular YouTube channels SciShow and SciShow Space, where videos I have written have garnered more than twelve million cumulative views. The episodes have been on a huge range of topics, from biology to fundamental physics and from general curiosities to breaking news. On this page, you can find all of the videos that I have written in one place, starting with some of my favorites:

How Close Can You Get To The Sun? — An episode about, well, how close you could get to the Sun—first as an astronaut in a spacesuit, then in a ship.

The Hunt for the Highest Melting Point — What materials have the highest melting points? What about the lowest? What makes all the difference?

Space Robots That Hop — What could be better than an army of robots hippity-hopping their way around Mars?

The Kugelblitz: A Black Hole Made Out Of Light — Einstein’s most famous equation allows for the creation of black holes made purely of light, as long as physics keeps working at the Planck temperature. Sixth-most viewed video on SciShow Space as of November, 2017.

The First-Ever Moon Landing — The Apollo 11 landing was one of humanity’s most remarkable achievements, and I had the privilege of writing about it.

Zeroing in On Dark Matter — The history of physics is full of null results that rarely get much publicity. The LUX experiment’s null dark matter result was a great time to spread the message that null results are just as important as famous discoveries.

Will the Periodic Table Ever Be Complete? — With every element up to number 118 officially having been created, the periodic table looks pretty full. But a full table doesn’t mean a complete one.
