is that... did he... did he really say that?

well... to be fair.......
Whenever I think about magnets I remember this Feynman interview where someone asks him why magnets behave the way they do, and he says that to answer a "why"-question you need a foundation where something is agreed to be true, and it seems like for electromagnetic forces we end up in " because that's how the universe is apparently".
Sure, but between nothing and the axioms of the standard model we end up with a fairly comprehensive description which can predict how different kinds of magnets behave in a wide variety of situations.
That's knowing how to use it, not how it works.
No, the theory of electromagnetism and by extension physics in general is knowing how it works. How to use it is engineering, a different set of knowledge which we also have some of.
Feynman was a bit pedantic sometimes.
This seems to be easily said of anyone trying to popularize science philosophy.
That is sort of how the universe operates though. You can have a greater and greater understanding of the underlying principles of physics but eventually you do get to "that just how it is". Why is there no such thing as a negative photon, apparently we just can't have a negative excitation in the photon field, no one knows why.
I mean one of the points he's making there comes up in every good science class: science doesn't answer 'why' it answers 'how'. The goal of science is to describe what we see in the world; science less about explaining things. Its easy to do without being a pedant. He's absolutely being pedantic on camera in that clip.
Like if you look at how people treat science now: MAGA completely pissing on it because its funded by snake oil people. Rich guys like Elon Musk cynically using it as a way to bilk the public and government. The press just has different goals than the scientific community and I would say that clip showed some of that friction manifest.
I'd expect nothing less from a scientist. Decrying pedantry from a scientist would be like decrying financial accuracy from an accountant.
Yeah. Each time we think we've got it, there's another hole to dig deeper.
With a lot of things:
You start off with no knowledge, and it’s a big mystery.
You gain some knowledge and feel like you have understanding.
You gain a lot more knowledge and you learn how much more there is that isn’t known.
The President is either at stage 1 or stage 3, take your pick.
No he's at stage 0. He has no knowledge but he doesn't investigate he just makes things up and then says that.
We're talking about the person who thought that stealth planes were physically invisible.
you forgot about the parallel imaginary number line (√-1), i think that is where the president lives.
Wish he was at stage 4...
You meant stage 2? "some knowledge and feel like you have understanding."
I guess those spinning magnetic pills one puts in beakers over a magnetic hot plate in chemistry labs are all an empirical hoax then.
Those are stir bars.
That they're magnetic is propaganda to push magnetic field bunk to sell more so-called "magnets". Stir bars are moved by phlogiston, which is why the liquid medium is often heated in tandem.
Please tell me you forgot the /s ....
Haha, 100%. I'm a scientist, I haven't believed in phlogiston in years!
Another phlogiston denier in an ivory tower. Tell me then, how does fire work?
JFC, how many times do I need to explain the workings of luminiferous aether?
/s
Serious time: we actually did briefly learn about all types of debunked theories in university, but as a component of the historical progression of contemporary theories.
Oh my god a real luminiferous aether believer. Basically christian theology. How fucking convenient for you, father.
Hey now, if you can tell me how light travels between two points without being facilitated by an entirely undetectable medium, I'm ALL ears.
They are protected by the PTFE cover, so the magnet is not in contact with water. Basic chemistry...
I always wanted kitchen cookware with a stirring pill. But it would require using glass or ceramic cookware on the stove. Which can be done to some extent but still feels sketchier than metal.
It isn't just that Trump is a dumbass, being uneducated and "stupid" aren't what makes Trump worthy of hatred and endless namecalling. Simply not knowing things does not make you a fascist.
It is the complete lack of curiosity people like Trump have that I despise more than ignorance, it is violently antithetical to the basic reasons I love science and the pursuit of understanding the world. I am curious, I ask questions, I don't just accept shit that people say because they say it a lot.
Trump hates people like me because we can walk all over him on basically any topic whereas people like me hate Trump because he does not desire to know anything beyond what he is forced to know.
Smart people will always admit when they aren't sure about something.
Idiots always know everything
The lodestones have always been, nobody knows their origin, or how they work. /s
I wonder if we could engineer some material that does fulfill his spec. Magnetic in air, loses magnetic properties underwater, regains them when out of the water...
An electromagnet with no waterproofing. Stick it in water, it shorts out, once it dries out it starts working again.
