Electrons is a charged particle simulator for iPad. It allows you to create dozens of positively or negatively charged particles, either freely roaming in space, or contained within conducting bodies. You can observe complex particle interactions and resulting electric forces, create capacitors, simulate a lightning rod, a cathode ray tube (CRT) and much, much more. Through play, you can effortlessly gain deeper understanding of many natural phenomena. Following the included guided tour of 10 experiments will give you further insights into the world of electricity.

"Tell me and I forget.
Show me and I remember.
Let me do and I understand."
– Confucius.

Nuke Effects for iPad

Museum piece from 1962, revived

This app is a faithful (although—for greater ease of reading—somewhat oversized) digital replica of the Nuclear Bomb Effects Computer, published by the U.S. Government Printing Office in 1960s.
