# Welcome to ALEP¶

This website is based off of **Advanced Level Experimental Physics**, a textbook
written by Bob Drach and Norman Price during their time teaching together at the
Ruvuma Boys’ Secondary School in Songea, Tanzania.

The first edition was published in 1987. With the help of Max Drach, we published the current edition as a Github project under a Creative Commons Attribution License. Enjoy!
