Yeah but then like that person said, they will disassemble the trolley in a weird way and put back together two trolleys, one on each track.

Yes please!

My MATLAB colleagues were jealous of my Matplotlib because the company didn’t purchase the plotting add-on…

I don’t know about unbound so I can’t really compare… OpenNic is not run by for-profit corporations, which I think is a good thing.

Opennic should be the default DNS of everybody!

He smoked for pleasure. I’m sure he ate and drank for pleasure.

If it was not clearly identified, even if I see it, I’ll intentionally fall in it to have an OSHA-paid vacation.

Bring this rock close to this other rock, and voilà. It creates magic heat!

Don’t get too close, because it will curse you to an agonizing death years later. However you can use this to boil water and channel the power of thunderstorms.

I’d like to see the triangle grow two additional sides, becoming a 3-sided pyramid. Then, a fourth pops up, turning into a typical 4 sided one. But then, a fifth appears, then a sixth, then more and more untill it becomes a food cone

Then it flips over and gets filled with ice cream. There, the perfect food pyramid!

In my late 30s, still doing it. I don’t expect to be rewarded though, I just want to toil away without being a dick to people around me.

The only vegan people i know are the most lovely, smiling, and funny people. I only know they are vegans because insufferable conservatives are complaining about them being vegans.

Holy shit, gotta try it now…

Entropy and complexity are not quite the same thing.

Low entropy is every Lego pieces separated by color and size, high entropy is every Lego pieces mixed up together evenly. Complex creations correspond to medium entropy.

If you compute actions of living beings, you’ll realize it acts as a catalyst to increase entropy.

I have old college textbooks in my library, Cohen-Tannoudji. I’m not sure about online resources though…

That sounds super interesting!

It is! Although it only deals with the day-to-day working of electromagnetism (quantum electrodynamics), but this explains the working of everything in our current life apart from nuclear power station and fusion in the sun’s core.

The text was written before we developed the model for nuclear forces (strong and weak), so it doesn’t touch that subject. We know now that sound and weak interactions work in a very similar way to QED, with extension for notre charges.

True! Thanks for the clarification, it’s been a while since i played with the maths of quantum physics!

After you measure a spin as 100% up, the state will be close to that for a while, si the next measurement has higher chance of being up, with this probability slowly decreasing with time.

Some properties of the electron are not present in photons, such as the lepton number and the electric charge.

It’s possible to create an electron positron pair out of a couple of high energy photons, but that is also true with many other elementary particles.

For a good intuitive introduction to this topic, i suggest Feynman’s book QED https://www.amazon.ca/QED-Strange-Theory-Light-Matter/dp/0691164096/

It’s a short read, and explains how positrons can be seen as electrons going backwards in time!

Welcome to quantum field theory! There is a single field for every type of particle in the standard model, but electrons are not made of photons.
