Two orbital things we might look for: 1. Activity in geostationary orbits. 2. Orbits where the planet's year is exactly divisible by its day, eliminating leap years.

Fredkin’s Self-Replicating Cellular Automata: Sum the neighbors, modulo 2, and assign to the cell on the next timestep. Astonishingly this allows patterns to replicate in multiple …

"According to biographer Robert Wright, the character Stephen Falken in the film WarGames was modeled after Fredkin." [ https://en.wikipedia.org/wiki/Edward_Fredkin ]

The only was I can remember which is port and starboard is by thinking about boarding an airplane. The steps/tunnel are always docked on the 'port' side, just as boats always dock …

Not hidden in the knitting in the sense of the specific stitches (which is also very cool: https://www.popsci.com/story/diy/secret-code-messages-knitti... ) but it seems she needed…

One route to understanding how CPUs work is to explore the computers that have been made in cellular automata. Golly ( https://golly.sourceforge.net/ ) has several, including one b…

I'm very skeptical of hydrogen as a general solution for reducing carbon emissions. It feels like greenwashing. "As of 2020, the majority of hydrogen (∼95%) is produced from fossil…

If this is true then Haskell's type system is Noether's Theorem.

This is an excellent app, it works very well. Thanks for linking.

I need this for my Android phone to compensate for a burnt-in image.

Gödel's incompleteness isn't a practical obstacle to proof assistants - it will never stop us formalizing proofs and searching for new theorems. It's irrelevant to their operation …

Imagine how much nicer the cities of the world would become with many of the offices turned into residential. There would be a rebirth of local community.

This is a great question!

An object at rest is still travelling through time. In fact it continues to travel at the same speed through spacetime when you let it go. It's just that spacetime is distorted suc…

With two space dimensions and one time dimension (2+1), an orbit in Newtonian physics is a helix. In general relativity that same helical path would be a straight line in an intere…
