Today i managed to purchased an old issue of the Otonanokagaku magazine (Japanese url). This is issue Vol.7 and the topic is on Steam Engine.
What is 大人の科学?
The Japanese has came up with a adult science magazine series explaining how the various science works. From pin hole camera, radio, static electricity to rocket engine and telescope. In each issue of the magazine, they include the history, the scientist involved and also a model kit.
