tech geeks Scientific and Mathematical Software

[ancientrichard]

I've been looking at free software. The quantity is immense, and the quality uneven but I very much like:

 

(1) euler, a freeware programmable scientific calculator that can do symbolic as well as numerical mathematics. I tested it with the integral of x^3*sin(x^2).

It is available here: http://euler.rene-grothmann.de/

 

(2) A freeware version of lateX, that euler can use to format its output, available here:  https://miktex.en.softonic.com/?ex=DSK-309.5

 

(3) A program called 'golly' for John Conway's game 'Life' from here: http://golly.sourceforge.net/

 

(4) A periodic table program that includes lots of information about each element and has links to a series of video clips, one for each element. The link is:
