💁🏻‍♀️ ICYMI: 🎵🎼 Before Edison's phonograph and #radio broadcasting changed everything, coin-operated musical automatons like this Regina #Music Box provided #entertainment in hotel lobbies and ice cream parlors.

Pianist James Shawcross demonstrates how the 1900-era floor-standing instrument uses assorted wheels to pluck a musical comb, creating melodies from metal discs with hundreds of precisely positioned projections.

This is not exactly new, but still, each time I think about downwind carts, by heads explodes again. It is not perpetual motion machine, but it looks like one! It just shows, that our intuitive understating how closed systems can extract energy from environment is oversimplified.

When thinking about how it is possible, it is probably somehow related to the fact, that ice skate sails can travel much faster, than conventional sail ships (sail foils can do better, but not as good as ice sails). And this can be combined with the fact, that cruising sail ship can actually outrun boat sailing just straight downwind. But this still doesn't help you to understand, how downwind cart works, except the fact the propeller also somehow "cruises", not in a straight line...

Contribution to the “#Quantum #Year #2025”

Foreword

To mark the 100th anniversary of the birth of “#quantum #mechanics” in #1925, #UNESCO has proclaimed 2025 as the “International Year of Quantum #Science and #Technology”. But as is often the case with such “UNESCO jubilee years”, they get lost in the “media mainstream”, especially when it comes to such “hard-to-digest fare” as quantum mechanics.

Hackaday: 8 Bit Mechanical Computer Built From Knex. “The K’nex computer is built by [Shadowman39], and this first video features just the ALU [arithmetic logic unit]. It can accept numbers from 0-255 or -128 to 127 and can add two of these numbers by storing them in registers using levers to represent each digit. A drive system underneath with a rack and pinion system operates on each […]
