Two sizes of slide rules (an old mechanical calculator), with their leather sheaths.

How many of you still have one of these? Or even know how to use one?

Ressorti mon "vieux" réflex numérique pour capter le charme du calcul analogique😍 🤔 @mathemarium.bsky.social #Maths #LorenzAttractor #AnalogComputer #DynamicalSystems #Nice06 #ArtScience @cnrs-insmi.bsky.social @univcotedazur.bsky.social @cnrscotedazur.bsky.social @ljad-off.bsky.social

Mission accomplished! ✅ After some soldering my #AnalogComputer THAT („THe Analog Thing“ by anabrid) can now easily be connected with an #Arduino to build a #HybridComputing setup. 😊

A slide rule is an #AnalogComputer but an abacus is digital. Think about that.

The simple definition to #AnalogComputer is this: a digital representation of a real-world, physical model.

The gyroscope in your smartphone is an electronic version of the physical object for the same job: so your phone’s software knows the attitude of your device in a 3D space.

Happy 200th William Thomson...the seafarer! A piece on his beautiful tide-predicting machine (a device w/ multi simultaneous independent discoveries) "Because of the complexity of the math involved [in tide prediction], many of these old brass machines remained in use into the 1950" #AnalogComputer

Metamaterials for Analog Optical Computing Novel metamaterial-based architectures offer a promising platform for building mass-producible, reprogrammable schemes that perform computing tasks with light.

An #AnalogComputer may be particularly suitable for tech such as #ArtificialIntelligence #AI. A promising direction involves #OpticalComputers that process information with light rather than with electrical currents. To do so, #metamaterials could be required. physics.aps.org/articles/v17...
