Gravitational G and How Science Works
17 June, 2021
Zak and Derek discuss the "controversial" value of Newton's gravitational constant G. They cover the history of its measurement and how the value (and confidence in that value) has changed over time.

Cosmology and the Arrow of Time
16 May, 2021
Zak and Derek discuss the big question: why is the future different than the past? Why do we remember the past but not the future?
Much the discussion comes from Sean Carroll’s book, “From Eternity to Here: The Quest for the Ultimate Theory of Time“

Relative Motion (Not Relativity)
30 March, 2019
Zak and Derek discuss a drone flying in an accelerating car. Does it stay in place? Fly to the back, front, ceiling, or floor? (And does the plane take off?)

Bell’s Theorem and EPR
21 March, 2019
Zak and Derek discuss nothing less than the fundamental nature of reality. They start with the arguments made in the Einstein, Podolsky, and Rosen paper from 1935, which were then tackled by John Bell in 1964 with Bell’s Theorem and Bell inequalities.

Encryption: Diffie-Hellman & RSA
8 November, 2018
Derek and Zak confirm they are talking to each other using the Diffie-Hellman protocol. Zak then encrypts a secret message using RSA encryption, which Derek then decrypts.
The Art of the Problem has a fantastic pair of videos on YouTube explaining how these encryption methods both work.

1 November, 2018
Derek and Zak discuss why there is a specific geosynchronous orbit distance at all. Why can’t it be any distance? And why is the escape speed what it is? Why can’t you move 1mph and leave Earth?
How Much Weight Do You Lift When Doing a Pushup?

Does Data Have Mass?
14 September, 2018
Is your cell phone heavier when it has more data stored in memory? What about an SD card? Magnetic storage drive? Is there a difference?
Zak and Derek dive in to the physics of flash storage, and what that means for mass even on the smallest of small scales. Electron mass? Einstein mass-energy equivalence? Is there any change at all?
