@notadampaul @Pacem_tw @smashdirt @ViralManager Basically, your description of physics neccesarily depends on the scale that you want to describe. A classical description is useless at the quantum level and vice versa.

@notadampaul @Pacem_tw @smashdirt @ViralManager Then I'm not sure you have a good definition of correct. The modern way to look at physics (I am in hep-th btw) is through the lens of effective field theory. Newtons laws (and N-S by extension) are absolutely correct within their domain of applicability.

seeing shit like this makes me question reality 100 million particles of water behaving exactly like water. at what point do we just admit the simulation theory might be right

@notadampaul @Pacem_tw @smashdirt @ViralManager And with regards to them 'not having solutions', they do! They are very solvable for all practical purposes through perturbation theory. This is how all calculations are done in physics for anything more complicated than a textbook problem. Do you think QFT is exactly solvable?

@notadampaul @Pacem_tw @smashdirt @ViralManager I mean Navier-Stokes is verified experimentally to the exact same degree that Newton's laws are verified experimentally; N-S is literally just N2L in a form that makes sense for a continuous medium. Would you deny that Newtons laws are correct?

@Pacem_tw @smashdirt @ViralManager no, that is catastrophically incorrect. At best, you can say "we have equations that water seems to obey sometimes, in the situations where can solve them" You cannot say you know something that hasn't been solved, proven, or verified empirically. Like, that is a literal lie

@Reeeeetheeeee @Ryuuu057 @awesumzombiefac Bro is terrible????

@Ryuuu057 @awesumzombiefac There’s no way bro is getting +1800 at the start im sorry it’s not happening

@Shinich08413513 @TeddySpaghetti3 Nothing more kvlt than bathory and venom my friend

@TeddySpaghetti3 I got out Fucking KVLTED.

@benkbullock @DiracGhost Not too hard to work through a book when you already know most of the material. Just gives extra little bits of insight into certain things

@DiracGhost Are you just posting them to get likes or do you read them?

Been using Landau and Lifshitz series quite a bit these past few months, and I got to say that volume 3, which is on non relativistic quantum mechanics, is becoming one of my favorite book on quantum mechanics. This one is not an introduction, and is not aimed at beginners, therefore, you might want to check out Griffiths and Shankar before you try your hand at this one. Go check out for a sample, chapter 3 on Schrödinger equation over at the internet archive, you'll thank me later!

@bcubeddd All Lagrangians are inherently classical no? In the sense that they lead to field equations for classical fields through EL eqns? The Dirac field obviously only has a physical interpretation once quantised, but the Lagrangian itself is classical

there are classical lagrangians for electrons and other fermions. the Americans decided they don’t know these exist and so they’re not to be found in textbooks

@https_hotpiss @tofeelhealed Not a single metal band would exist without sabbath

@tofeelhealed To be honest most of my favorite metal bands actually would have existed without Black Sabbath

put the octanecore down dummy it’s time to learn about a band called black sabbath and how without them you wouldn’t have any of those bands you’re willing to camp days in advance for

@sabbathfans @Daewolf Do you actually even like metal?

@Daewolf I had them muted the entire time except for their Sabbath cover.

@onehappyfellow @martinmbauer Exactly. The masses depend on the vacuum expectation value of the Higgs field at its minima.

@Jake_M_Wilson @martinmbauer Ag ok, so with Higgs your theory still has the required symmetry and the mass comes from the value the Higgs field happen to settle on?

13 years ago today, the discovery of the Higgs boson, the central piece of the Standard Model, was announced! What’s something you've always wanted to know about the Higgs boson? Ask away!

@onehappyfellow @martinmbauer There's nothing stopping you from just adding a mass term to any lagrangian, but mass terms added in this naive way lead to lagrangians that aren't invariant under the required gauge group. The Higgs lets us keep the invariance, while adding mass in a roundabout way

@Jake_M_Wilson @martinmbauer Thank you, that actually makes sense - other than I don't have an intuition why the theory without Higgs is massless?

@onehappyfellow @martinmbauer ... to the previously massless gauge field, giving these new fields the necessary components to make them massive, as is observed.

@onehappyfellow @martinmbauer If we try to try to create a langragian that respects this gauge group, we find that the associated gauge fields are all massless. If a scalar (Higgs) field is added to the model, it permits massless boson modes that 'lend' one of their components to the ...

@RshdwWarCollege @CraigMak2 @darthtrump2028 @nikicaga I'm an actual physicist and you are talking out of your arse

@CraigMak2 @darthtrump2028 @nikicaga Look up the blackbody radiation curve, kid. Photons aren’t interchangeable. They differ in frequency more than mere color temperature can represent. Also, LED bulbs flicker in ways that incandescent filaments simply don’t.

It's crazy how we made lightbulbs that are just objectively better in every way and some people still hate them

@BrenoGF144 @hrachyshka @charlieboardman @tenobrus Sheet of paper is easier to carry than a laptop mate

@hrachyshka @charlieboardman @tenobrus Can't bring it everywhere

@Benzinixo @J_B__7 @secondtierpod How many times a year is the Super Bowl held?

@J_B__7 @secondtierpod How many times is the British grand Prix held a year? If it was every week, attendances would die down. Collage football attendances could rival them tbf

Lol

@cybermilesb @captgouda24 @littmath You think maths departments are giving out easy A's?

oh, didn’t realize you were a math tutor in college. fwiw I think ANDREW WILES has taught some math classes himself

@alt_Lok @martinmbauer Show me your physics degree

@martinmbauer GPS does not need relativistic anything to be precise.

If you can find a single experiment that contradicts special relativity your paper wouldn't just get published, you could start looking for hotels in Stockholm SR is accepted because it is confirmed experimentally literally every second every day. In fact, you test its predictions every time you use GPS -without relativistic corrections, it would be off by kilometers
