About This PHP Science Labs Wiki Site

There is NOT any spam, malware, adware or ads on this Wiki site.

This site began as a private extension and repository site to test and store some science, math and astronomy programs I wrote in PHP before releasing them on the Internet.   Since quite a few people expressed an interest in some of the programs over the past 22 years at my NeoProgrammics site, I decided to collect much of that work at a single location to more easily organize and share it with others of similar scientific and programming interests, especially students of the subjects.

The links point to programs in a public domain PHP software and source code collection on this web site.
Some of the programs are old, dating back their origins in PHP 5 and updated to maintain upward compatibility.

FOCUS:  Astronomy, Physics, Mathematics, General Science, Math and Science Programming in PHP (With a tiny bit of Java Script).

Lunar Hemispheric Phase Explorers-HD Edition For Large Monitors
A virtual space telescope for larger monitors to view the entire moon at any relative phase from above four hemispheres (Near, Far, East and West hemispheres) in HD detail.

A freeware lunar surface rendering program script for use with the free, open-source POV-Ray ray-tracing sofware. LUNEX is the program that rendered all of the lunar phase images used in the Lunar Hemispheric Phase Explorers - HD Edition program mentioned above.

This program computes the dynamical latitude coordinates of the Arctic and Antarctic circles over the 10,000 year span from 3000 BC to 7000 AD.
