I think in the case where they don't annihilate they will just scatter off each other.

That's a very deep question. In some sense no, in some sense yes. I would say on the deepest level, no, they are not blocked.
Re:So you want to learn physics (second edition, 2021) on Monday July 20, 2026 @08:56AM (#48978248)
Hi, fair enough. I've thoroughly immersed myself in this stuff enough that I sometimes don't realise people aren't as familiar with the concepts and jargon. I'm going to write another article that I think should help about the Klein gordon equation, at some point.

See my last article here https://forwardscattering.org/page/Intuitive%20Quantum%20Ele... Although it is a bit technical. next one will start simpler.

Are you saying my statement is very abstract? or down to earth?

ok? well, textbooks can be wrong or misguided.

Nah, special relativity is a consequence of magnetism.
Re:Maxwell's Equations Were Discovered [video] on Thursday July 09, 2026 @11:15AM (#48847342)
Interesting, I need to look into Maxwell's original formulation with the vortices. You can write electrodynamics in terms of small spinning elements: https://forwardscattering.org/page/Intuitive%20Quantum%20Ele...
Re:Connections in Math: the two kinds of random on Monday July 06, 2026 @06:15AM (#48802738)
Kolomogorov complexity as an objective measure of the information contained in a string just doesn't work. It depends entirely on the language used for the program, and for any string, in some language, the complexity is zero.

See https://forwardscattering.org/page/Kolmogorov%20complexity

And no, the invariance theorem doesn't save you.

Re:Midjourney Medical on Thursday June 18, 2026 @06:14AM (#48583253)
Wonderful stuff, good job Midjourney.

An AI can be trained on body scans to detect diseases, tumours etc. Ideally this can be trained on real scans with real diseases but you could also train on synthetic data (synthetic bodies and/or synthetic diseases).

You can also focus ultrasonic waves to destroy (vaporise or cook) diseased tissue.

Re:A Decade of Slug on Wednesday March 18, 2026 @07:50AM (#47424505)
So now the algorithm is patent-free, and the vertex and fragment shaders are open-sourced with the MIT license, what we presumably need is some open-source code to take Bezier curves from a font file (or from the loaded data from FreeType or whatever), and process them into the data format that Slug expects.

Also thank you to Eric Lengyel, I have had my eye on Slug for a while and wished it was open-source.

Re:A Decade of Slug on Wednesday March 18, 2026 @06:08AM (#47423689)
Awesome, thanks.
Re:A Decade of Slug on Wednesday March 18, 2026 @04:51AM (#47423244)
I was going to ask if Slug can be used as a general vector renderer. Or does it assume limits on e.g. number of curves/paths per area that are typical of fonts?

Re:Analytic Fog Rendering with Volumetric Primitives on Friday March 06, 2026 @07:08PM (#47282819)
For simple models (constant incoming radiance), you can indeed just add the optical depths from the different fog 'layers'. (90% sure but the maths is easy to check anyway, see https://forwardscattering.org/post/72)
Re:Analytic Fog Rendering with Volumetric Primitives on Friday March 06, 2026 @07:05PM (#47282782)
Coincidentally I just posted a blog post on fog rendering, in particular with exponential height fog, yesterday: https://forwardscattering.org/post/72

Use a multithreaded blocking approach. Much nicer than async.

Re:OpenClaw Is What Apple Intelligence Should Have Been on Saturday February 07, 2026 @08:27AM (#46923684)
I haven't thought about it deeply. But I guess it's about allowing the model to easily distinguish the prompt from the conversation. Models seem to get confused with escaping, which is fair enough, escaping is very confusing. It's true that for the transformer architecture the prompt and conversation are in the same stream. However you could do something like activate a special input neuron only for prompt input. Or have the prompt a fixed size (e.g. a fixed prefix size). And then do a bunch of adversarial training to punish the model when it confuses the prompt and conversation :)
Re:OpenClaw Is What Apple Intelligence Should Have Been on Thursday February 05, 2026 @07:01AM (#46898721)
They could be if models were trained properly, with more carefully delineated prompts.

Re:What Happened to WebAssembly on Friday January 09, 2026 @07:15AM (#46553094)
I use webassembly for Substrata (https://substrata.info/). It works pretty well, allows building a c++ app using OpenGL for the web.
Re:Aliasing on Monday December 22, 2025 @07:15AM (#46353559)
When you have done enough C++ you don't need to fire up compiler explorer, you just use local variables to avoid aliasing pessimisations.

I also wrote about this a while ago: https://forwardscattering.org/post/51

Do it properly with quotes you lazy people :)
