Actually, analog computers have a long and glorious history. The advent of transistors meant that digital computers won the war and became ubiquitous, but if instead of a universal machine you want something that does exactly one thing, but very fast and very efficiently, analog systems are often the way to go.<br/><br/>In particular it is tempting to do computation with light. Light is extremely good at transmitting information, we have excellent technology for both generating and detecting light, and we are VERY good at manipulating it. Furthermore light is FAST, and if you do things correctly losses are low.<br/><br/>And if there is something that would benefit from being made massively parallel, fast, and with limited energy consumption it is machine learning. Now, not all forms of machine learning suit light well. People try to make deep neural networks using light, but I am not convinced that this approach has legs. A less popular approach to machine learning that is a perfect fit for light and optics is &#34;reservoir computing&#34;, where you have a large recurring network where all the weights (i.e. how strong the connections between the nodes are) are fixed, and you only train a single linear layer (effectively you just do a linear regression) at the output of the network.<br/><br/>1/2<br/><br/><a href="https://arxiv.org/abs/2609.02733">https://arxiv.org/abs/2609.02733</a> 2026-09-03T09:34:11Z https://nostr.now/nevent1qqs8wz4z2vr5f6wu57k55x9t3urp4e2dhrg6z5hng0t24hrsls36gmgzyrsy4wrn52sk6wqez8h74gerup3uqu5x4hu9p4m9zgkjwgatmcqjy90x0wx In reply to <a href='/nevent1qqsxfu4mgq2pxv6j6frhdg40fm0wv8w8nt9zgplkww4gr6vjxufccdqxwmxzy'>nevent1q…mxzy</a><br/>_________________________<br/><br/>I have bothered John with questions before (I owe to him most of my understanding of both tensors and spinors).

This is not very surprising as it is a ray optics result, while most experts spend their days thinking in terms of waves. It is also not very difficult to understand, hence this brief thread.<br/><br/>The &#34;etendue&#34; of a beam is defined as the area of the beam (normal to the beam propagation), times the divergence of the beam (expressed as a solid angle), times a prefactor that accounts for the refractive index of the medium. In linear (ray) optics, this quantity is conserved, which means that the only way to reduce the divergence of a beam is to increase its size, focusing a beam requires increasing its divergence, etc. Interestingly, as there is a maximum possible divergence a beam can have (solid angles can not be bigger than 4π), there is a limit to how small one can make a focus. This is obvious in wave optics, but much less so in ray optics!<br/><br/>&#34;Conservation&#34; of etendue is a bit of a misnomer. A linear optical system can easily increase it (e.g. by using a diffuser), and a lossy operation can reduce it (e.g. a pinhole). Still, a useful concept to have in mind when thinking in terms of rays. There are several ways to prove &#34;conservation&#34; of the etendue. Which one clicks with you will depend a lot on your background and personal preference.<br/> 1/ 2026-07-16T09:30:36Z https://nostr.now/nevent1qqszu0jwm69yd5q30r7j3kfl6jja0aqu3g42e0mmrmp79dmmrdn5dtszyrsy4wrn52sk6wqez8h74gerup3uqu5x4hu9p4m9zgkjwgatmcqjys9afc6 In reply to <a href='/nevent1qqs9dzs5ua0vp9kukye2m8zq8uz9x9ukf0njm06gut8dlh663vp5mjgvx3lw9'>nevent1q…3lw9</a><br/>_________________________<br/><br/>This looks like a bummer!

When Berlusconi collapsed under the weight of his age and scandals, things didn&#39;t get &#34;back to normal&#34;. What happened was that the bar of &#34;normality&#34; have been moved forever, the opposition was essentially cancelled, and the power vacuum was filled by populists. 2025-07-18T14:27:41Z https://nostr.now/nevent1qqsx3g57ghtetqu0a639es72we9f9c2phhqpw3ph8qpn8tq5hyt7xgszyrsy4wrn52sk6wqez8h74gerup3uqu5x4hu9p4m9zgkjwgatmcqjy99euq4 It is interesting/horrifying how Trump seems to be following exactly Berlusconi parabola (including a scandal involving underage girls and having people he didn&#39;t like fired from TV), but cranked up to eleven. 2025-07-18T14:22:56Z https://nostr.now/nevent1qqs2fjvdyjh8wqjvta6tsyuxtjeup4yewk8d4rln7szqaezvjzd6nqszyrsy4wrn52sk6wqez8h74gerup3uqu5x4hu9p4m9zgkjwgatmcqjyl6z437 In reply to <a href='/nevent1qqsr4a4fzmp0vxphq0l4s4qv0fdwlwfmyetd6gfgv6j9djfgqhtkp5cwdr2ml'>nevent1q…r2ml</a><br/>_________________________<br/><br/>#PhysicsFactlet <br/>An improvement over the bisection method is the so-called &#34;false position&#34; method, where instead of dividing the bracket region in two, you cut at the point where the line through the two bracket extremes crosses zero.<br/><br/>#Physics #Computing #Algorithm<br/><video controls width="100%" class="max-h-[90vh] bg-neutral-300 dark:bg-zinc-700"><source src="https://media.mathstodon.xyz/media_attachments/files/114/852/544/088/999/242/original/6963e9fe05b290ad.mp4"></video><br/> 2025-07-14T16:36:10Z https://nostr.now/nevent1qqsr4a4fzmp0vxphq0l4s4qv0fdwlwfmyetd6gfgv6j9djfgqhtkp5czyrsy4wrn52sk6wqez8h74gerup3uqu5x4hu9p4m9zgkjwgatmcqjyzu2z7a #PhysicsFactlet <br/>Finding the roots of a function is a very common problem in computational Physics, and the bisection method is a simple and effective (albeit far from optimal) way to do that.<br/>The idea is that you start by &#34;bracketing&#34; your root between a value of x where the function is negative and one where it is positive.

The question &#34;how much information is still there?&#34; is not particularly interesting as the answer is &#34;essentially all of it&#34;, as elastic scattering can&#39;t destroy information. A much more interesting question is &#34;how much information can we retrieve?&#34; In order to even try to give an answer we need to be a bit more specific, so the authors placed a small reflective surface behind a scattering layer and asked how much information about its transverse position could be retrieved. This is a well-posed question, and the answer takes the form of a &#34;Cramér–Rao bound&#34; (<a href="https://en.wikipedia.org/wiki/Cram%C3%A9r%E2%80%93Rao_bound">https://en.wikipedia.org/wiki/Cram%C3%A9r%E2%80%93Rao_bound</a>).<br/>After estimating this upper bound, the authors investigate how well a trained neural network can do at this task, and show that a specifically built convolutional neural network can almost reach the theoretical bound.<br/><br/>[Conflict of interest: Ilya Starshynov (the first author) did his PhD in my group.]<br/><br/>#Physics #InformationTheory #Optics #MachineLearning 2025-06-02T15:16:17Z https://nostr.now/nevent1qqsgqckqxxm879xcxly078lcjyfug77l8d7f99ca0tydlk3aqnj0zcczyrsy4wrn52sk6wqez8h74gerup3uqu5x4hu9p4m9zgkjwgatmcqjyn3q2sc #PhysicsFactlet <br/>A Shack-Hartmann sensor is made my an array of small lenses and a camera.
