Leon Foucault demonstrating the Effect of the Earth’s Rotation

Leon Foucault demonstrating the Effect of the Earth’s Rotation

On January 3, 1851, French physicist Leon Foucault started to experiment with his eponymous pendulum, by which he was able to prove the earth‘s rotation. Actually, how can you prove that the earth is a rotating orb in an easy-to-see experiment and – of course – without spaceflight? By today, Foucault’s simple device is part of numerous natural science museums around the world. The Pendulum Ok, how does Foucault’s pendulum work? The apparatus consists of a…

How the ARPANET became the Internet

How the ARPANET became the Internet

On January 1, 1983, the ARPANET as predecessor of today’s internet switched from NCP (Network Control Protocol) to the TCP/IP protocol, and the ARPANET then became one subnet of the early Internet. “There are some people who imagine that older adults don’t know how to use the internet. My immediate reaction is, “I’ve got news for you, we invented it.” — Vint Cerf, a “father of the internet,” quoted at age 73 in…
