THE PRECISION PARADOX

More photons can reduce shot noise, but precision has a physical cost.

Explore the limits of analog optical computing and next-generation photonics, looking at everything from photon budgets to real-world hardware accuracy.

To tell if a maze is solvable, just hang it by its corners

If it tears into pieces, you’ve found a solution

Sandia ran a 65,536-point FFT on an analog in-memory chip (SONOS flash, 40 nm). Measured: accuracy, 41.1 dB PSNR. Modeled: the energy gains. Analog drifts silently — check it against a digital FFT on a schedule. #AnalogComputing #Hardware

The patch panel is the iconic image of an analog computer: a board of wires you rewire for each problem. Bernd Ulmann, who builds and restores these machines, makes the case for leaving it behind, and shows the reconfigurable computer he built without one.

George Dyson, historian of technology: as we build an essentially unlimited amount of digital processing, more of our computing ends up resting on continuous functions. Analog is back, whether we like it or not.

Clive England of cray-history.net on the bet behind Cray supercomputing: breadth over depth, many simulations over one perfect answer.

David Alan Grier on the 1946 Moore School lectures: the people building digital computers treated analog as the old style, and most of them wanted to set it aside entirely to focus the money and attention on the stored program digital computer.

Bernd Ulmann, who builds analog computers, predicts that within twenty years they will sit inside nearly every machine as co-processors, about as routinely as graphics cards do now, handling AI and differential equations alongside the digital computer.

Bernd Ulmann: an analog program is a spaghetti of wires that turns the machine into a model behaving just like the problem you want to solve.

Peggy Kidwell, curator emerita at the Smithsonian: most visitors now arrive carrying a computer and use it more than they look at the objects in the cases. So which device deserves to be called the most important? It gets complicated.

Bernd Ulmann, who builds analog computers, says he truly understood several branches of mathematics only after building the problems on an analog computer and watching them run. In his words, a wonderful educational tool.

Clive England of cray-history.net on Cray supercomputing: rather than analyzing one problem in exhaustive depth, the idea was to run tens of thousands of simulations in parallel and study the average of what came back.
