The right part consists of a germanium crystal, one single point-contact made of gold, a lamp and a battery. The battery is placed with the positive pole versus the n-type area of the germanium crystal. The negative pole is placed versus the p-type area and as in the example of the reversed biased diode no current is present in the circuit. The lamp does not shine.

About the educational games

The educational games are based on Nobel Prize awarded discoveries and were produced between 2001 and 2012. The games have not been updated since production (including potential scientific facts changes) and are provided here on an 'as is' basis by popular demand.

Some of the games run using Ruffle without the need of any plugin, but most of the games still require Adobe Flash Player. Flash is an old technology that has reached end of life. These games will no longer work without a dedicated setup. If you are depending on these games in your profession, please advice your local IT support. We do not have the resources to provide support.

We are working on supporting other games using Ruffle as well. We also hope to publish a new version of the Blood typing game, our most popular game, in mid-2021.
