Сегодня всем известно, что скорость света в вакууме является неизменной, а ее величина — максимальная скорость среди возможных во Вселенной. Но в течение истории она претерпела множество уточнений, пока в 20-м веке не перевернула всю физику вверх тормашками.
Именно об этом — об истории измерения скорости света — и о ее значении, как физическом, так и для физики в целом, мы сегодня и поговорим.

Could humans ever travel to other galaxies within their lifetime? The immense scale of the Universe seems to prohibit such voyages, after all the nearest galaxy is so far away that it takes light itself — the fastest thing in the Universe — 2.5 million years to complete the trip. Remarkably, there is a trick that might allow humans to accomplish this feat — join us today as we step onboard the constantly accelerating spaceship!

Matt Parker and a team of Domino Computer Builders balanced over 10,000 dominoes in a carefully designed circuit. The result was a Domino Computer capable of automatically adding numbers. It can take any two four-digit binary numbers and return the five-digit binary sum.

Its a computer, made of dominoes.

Gravity Industries make jetpacks. Theyre not practical. Theyre not meant for mass use. But they are a lot of fun. They asked if I wanted to try flying one. Thanks to gravity.co/ — this is not sponsored but, obviously, they did give me a flight in a jetpack.
