Mass on Spring Resonance

A mass on or attached to a spring enters resonance upon being excited. Unlike a pendulum, its frequency does not depend on gravity. See http://hyperphysics.phy-astr.gsu.edu/hbase/shm2.html The accompanying program provides a simulation of such a resonance. The program is suitable for iPad and iPhone...

Re: Chorale from St Matthew Passion

Sad but beautiful music.
It becomes a bit more cheerful if you increase the tempo.
The ending seems a bit abrupt.

Re: Extension of NOTES

I really don't understand anything about accelerando, diminuendo, ritardando, etc., but I think your program is a special achievement.
Hopefully Mr Kibernetik sees it as a valuable suggestion to add it to the app.

I ran the program for two days. It's remarkable that after a few hours, the interval remains almost constant at two hours.

Re: Game of Hamurabi (modified)

Nice game, but it gets a bit boring towards the end.
You might want to add more disasters or costs for the inhabitants of the growing community.

I also discovered a small mistake.
After 15 rounds (years) I received the evaluation and the invitation for the 11th year.
