Get ready for more aged like milk comments, Sabine just released a video with “MOND is so back” across the thumbnail

Betas, betas everywhere. The second hand cringe is almost unbearable. WTF? If y'all are bad at physics and can't get your own doctorate just SAY THAT. how embarrassing.

Magnetism was first known to humanity in the form of permanent magnets - lodestones and such. Centuries, millennia ago. When magnetism was explained in the 19th and early 20th centuries as arising from moving electric charges, that explanation didn't do much if anything to explain what permanent magnets are. It took the rise of quantum mechanics to fully explain magnetism in our world.

Different question Angela...Does ant-matter really move backwards in time? And if it does, wouldn't that solve some of the issues about why all the matter didn't annihilate the antimatter during the big bang and vice versa? I have occasionally heard/read that antimatter moves backwards in time. Can you straighten me out on this question?

If you don't like corpuscles, you won't like crepuscular rays. Sounds like a blood disease, but refers to sun rays coming up from behind clouds, or shining down through holes in clouds. The Japanese flag is a representation of them. Remember Pearl Harbor!

Great stuff! Thanks! I have had trouble finding science communicators for this real high level stuff.

You're my favorite physics channel, the fact I'm from Frankfort has nothing to do with it. Out there reppimg that we're not all mainlining mountain dew and ho-hos... I mean cupcakes compliment the Dew much better,

re: 31:16 onward... Just...wow...like <bites fist> DAMN!. I have never seen anything like that before in my life. These physicists represent the tip of the bleeding edge of the work and research of planetary science, astrobiology, if not astrophysics as a whole and the silence from the super-majority of them is deafening! He is the loudest one in the room and is the example par excellence of what you have been describing thus far. The hubris combined with the complete lack of composure is mortifying! My favorite is the expression and gesticulation of Paul Hoyningen-Huene (researcher in the philosophy of science specifically Neo-Kantian interpretations of Kuhn and Feyerabend) directly to the right of Prof. Loeb as he, along with Sara Seager, Steven Beckwith et al. listen attentively to Loeb's practically self-immolating diatribe against the rational critics of his poorly founded and irrefutable conjecture. Really though, Paul H's finger resting on his lip makes him look as though he is about to ask Loeb (after a period of uncomfortable silence once he runs out of steam), "So Avi...how have you been feeling lately? How are things at the CfA? Did you see the new 'Dunkirk' movie?"

This video doesnt really prove the intial point, it also completely follows that you don't understand qcd (don't take that as a jab, I would say no one does)

Feynman is the CHAD of psychics and a little bit of a h0e😂. I LOVE HIM. "Physics is like sex: sure, it may give some practical results, but that's not why we do it." Richard P. Feynman

I love it when you talk data... I'm relieved. At first I thought this was going to be about invasive aggressive spiders escaping from the lab in a plutonium container stolen by Libyan terrorists, and turning them into Spidermen. (Copyright 2024)

This is on point. You ATE that. Veritasium did a complimentary descriptive, check it out too, between the both you're 10% there🎉 ETA i lied veratasium did an explanatory on the HIGGS, to INCLUDE QCD, there's a great visual of pretending to be gluons. So if you go hunting just type Veratasium Higgs, it'll come up.

The Galileo comparison is a little funny because Galileo’s reception probably had more to do with his personal conduct than his ideas. Copernicus’s work on heliocentrism was well received by the Catholic Church. Copernicus dedicated De Revolutionibus to the Pope and his work went uncensored for 70 years. Galileo on the other hand publicly insulted the Pope and other scientists all the time. Although the Catholic Church was also facing pressure from the Protestant Reformation that was criticizing the Catholic Church for not interpreting the Bible literally enough.

More trash content

JUST HUSH.....humble yourself. BLAH BLAH BLAH...

You're not a failure at communicating its just most people on the internet fail at being communicated to

I came to understand that QCD was so complicated we can't even do the maths for it without computers. I was also filled with trepidation about how chaotic things were that level... it's a wonder that they resolve themselves into protons and neutrons at all!

I have a basic background in science and environmental communication and I had a friend with a industrial engineer title that had weird views about the world (one of them science) that made it very uncomfortable to have any disagreement. He would say weird crackpot theories about many different topic with so much certainty and arrogance that it became very difficult to have casual dialogues about science or anything, even democracy (he was certain that we need a random system for electing congress representatives). In science topic, he would postulate that human had outside alien help with the building of pyramids, he would say that Einstein was wrong about time relativity or that paleontology wasn't a science. It wasn't just different worldviews about politics, it was different attitude and aptitude about science. Those dialogue eroded the friendship to the point it was dense to be around because we had different stance on everything. Good thing the friendship ended, although for other reasons.

"I don't like Feynman diagrams" Later: "And here's *another* Feynman diagram to explain *this* thing" We're up to at least five so far, and I ain't done the video yet 🤔

Future t-shirt nominations from this one: "Positively-Charged Boy" and "Einstein's Little Baby"

I like her attitude. Like packaging life and death inside one personality lol

There's always some small-minded guy in every group. They never seem to know when to stop, even though they've been called out many times.

This is a brilliant video. You are super funny!

"It's all about electrons babe" -Albert Einstein

The exchange of photons in the Coulomb force does not actually happen. In this case, the photons are virtual photons and are just a calculation tool in perturpation theory. There is no actual measurable photon exchanged.

A friend was hired to teach physics at a college but was ordered to teach it without math. He resigned.

At this point I support the demotion just because its become one of those supposed binary questions people obsess over, to which my answer is "whatever pisses off the largest number of people" Toilet paper rolls? Don't personally care, till someone asks. Pineapple on pizza? Again, not my thing, don't care, until you make it a point to ask.

All I've taken from this video is time-traveling penguin cartoon math. Oh, and that photons being only 1% mass is existentially creepy.

That Tam Elbrun reference was gold

I'm pretty sure I've had a nightmare like this once.

I very much enjoyed this talk, and it reminds me of a thing I read years ago about how many "proofs" of Euclid's Parallel Postulate mathematicians used to have to deal with (I think that was from Simon Singh's "Fermat's Last Theorem"). I try not to do that sort of thing. But in retirement I have to confess - I was always interested in physics and have been reading a lot of popular works on quantum physics and so forth. And of course I can't do the math. It's still very easy to let my mind wander through possible ways of understanding things, and come up with mental models or visualizations to try to make it easier. Reading about how much work Dirac put into his equations for half-spin particles was really interesting though, especially finding that he thought through far more ways of thinking through the problems than I ever could - and then he developed formulas to test their predictions, and rejected all the ones that didn't work. Reading that makes me appreciate the work a lot more, and hopefully is an antidote against being a crackpot. The odds of me thinking of anything valid that hasn't been tried is close to zero.

The "Oops All Pluto's" simulation at the end didn't change the solar system much, but it would be incredibly destructive for several of the planets if we included their moons. This is because several moons are more massive than Pluto (Our Moon, Saturn's largest moon: Titan, Neptune's largest moon: Triton, and all 4 Galilean moons).

I hate the term. Dark (adj.) Matter (noun). Layman- "What is dark matter?" Scientists- "We don't know" Layman - "What a mysterious substance" Scientists- "We don't know what it is" Layman- "We do know it's dark" Scientists- "We can't see it" Layman- "Ohhh, it's invisible" Scientists- "We don't know" Layman - "This sounds like BS" Scientists- "What sounds like BS?" Layman- "Dark Matter" Scientists- "We don't know what it is" Layman- "What a quack" Scientists- "I'm not that kind of doctor" (arrogant chuckle in an English accent)

I think you might have to do a vid on magnets at some point in the future. You casually dropped in that magnets move apart by electrons exchanging photons, but then left the viewer in the dark, thinking about magnets on opposite sides of opaque materials that photons can't pass through, or magnets attracting each other. All sorts of instant questions raised... -Albert Einstein (just to stick with the running joke from the rest of the comments :)

6 year old Feynman could have understood

Yes! Yes! All of this, yes!

A theremin would be an awesome gift for me. I'll never get one, most likely, as a present… oh well 🤷‍♂️

I wonder if I could cook some of that dark stuff up on my kitchen stove.lol

I'm watching this 10 months after it came out, because I'm stuck home with covid, and probably my mind isn't as sharp as usual, but I'm sure no will read the comments this far out so I can tell you: I'm going to start a scam selling dehydrated water. Thanks for the tips on how to sell it!

It's all dinosaur pee!

this history of string theory seems to be an exceptional example of the general plague making science terrible, that everything is kept aloft by chasing grants, and if you bend the truth a bit your funding might change by multiple orders of magnitude. i see a lot of sizable grants funding university department teams that realistically aren't going to make the impact the team name suggests, but the obvious example is fusion research. all those headlines aimed at the general public screaming about the OMG MASSIVE BREAKTHROUGH but frankly it originates with insecure researchers trying to generate excitement with non-expert journalists when incremental improvements hit an arbitrary number that is unrelated to the practical breakthrough the public is imagining. also to blame afaik is young reporters covering trivial tasks and wanting to sound like they were there when teleporters were invented ... but fusion researchers are deliberately choosing their words carefully to create the wrong impression. i don't think fusion researchers are less honest than other fields, and to a degree we're seeing anonymous scientists getting understanably excited at the prospect of a bit of adulation, but fusion moves a lot of dollars when public perception shifts

i didnt got my qcd class at uni, now i know why

33:07 - I think strictly speaking the epicycles weren't wrong so much as they were overly complicated? Like, you can, in principle, describe Mars' orbit from Earth's POV *exactly* by simply adding infinitely many correcting epicycle terms, I think? It's basically just a Fourier transform. Just so happens that the math becomes vastly simpler if you go heliocentric. Of course the predictions of the epicycle models people had often weren't very precise, perhaps because that would have required more such epicycles than could reasonably be calculated by hand at the time.

I honestly just took you at face value when you said Einstein said that thing and I need you to not play with my trust like that

Yeah... But what about QGP?

Dont be jaded by complex quotes. You can't take it that literally. He's not saying that a 6 year old would be able to understand deep quantum mechanics. He is saying that if a child were to ask you about it, would you be able to come up with a metaphor well enough to have a child understand the principle. The quote is literally designed to invoke anger, and expressing that anger and doubling down on it to crush the quote is what the quote is about. Revealing your humility in your prospective field.

I love your videos so so much but, earnest request, could you please mix your audio slightly louder 😭 its hard to hear when I’m commuting

I love your videos.
