Programs for physical phenomena

Posté le 15/11/2019 18:01

Dear programmers,

sorry for writing in English, but my French is real bad.

I use my Casio fx-CG20 mostly for simulation programs, which cover fields of physics, astrophysics or similar topics. I published some of them here. You may try my map projection program which shows how different a world map look like if you present it by different methods. You can look at the formulae in it: Most of them are rather simple.

In the last days I thought about wave optics and experimented with it. I found it very interesting, that a real image can be constructed simply by overlapping (interfering) of spherical waves from a couple of points. You don't need to take into account the laws of reflection or refraction, the wavelets konws these law for themself? Very exciting. You may look of the simplest one, diffraction at a slit or the more complicated image formation by a parabolic mirror.

All programs need C.Basic from sentaro21.

Hello
English isn't a problem on this forum.

Could I ask you why you publish those has text files ? It's not handy to put on a calc.

You have to use C.Basic anyway. In C.Basic it does not count whether you have text or .g3m. It works the same way: You may start .txt directly.

Ascii files have the advantage that you may look at it and understand how it works, even if you don't own the same calculator model. Beside this, you may adapt it to another PPC or even another programming language..

OK no problem, I didn't know this before

Now that's something new! Thanks for sharing your work.

You seem to have linked the same program twice.

Thank you, I corrected it.
