5. Shell Models and Quantum Numbers (Intro to Solid-State Chemistry)

[@landonschmitt7117]

When a lecture shakes your fundamental understanding of certain topics lol. I doubt this will be the last time 😂 Who knew a t-shirt and coat could be so fashionable and comfortable. Absolutely mind blowing

[@shaulstein3749]

Thank you very much MIT and prof. Grossman for this amazing course

[@oreoluwax6322]

Thank you so much from Nigeria. You've made chemistry a lot easier. He's an excellent teacher.

[@dancooper8551]

Physics + Chemistry = ❤📚

[@shintarokohata8178]

thank you from Japan

It does make me wonder at what point one should potentially reconsider the entire model.

[@oskarstenlund]

Ideally 100 years ago.

Na, it's called the in wonderland award 😂😂

It has technically changed. Were found smaller particles within these particles. It’s also sort of weird that we have no idea what someone them are made out of. Like wtf is an electron made out of? It has a small mass, it must be made from some kind of matter.

[@Paraselene_Tao]

Something which always bothers me when I study the double slit experiment is that I wonder what the observer is. What device is the observer and how does it work?

[@Paraselene_Tao]

I read q little more detail about this detector. It was first proposed as a thought experiment. It was tested in the real world in 1987. The 1987 test showed that the wave is detectable before it becomes a particle, but the more accurately you detect the wave, the more the wave function collapses and produces a particle.

[@abhijeetkumar9483]

have you got an answer? pls tell

[@asrafulrefat1995]

same bruh. i get confused over what observing is

[@sarahlevi4081]

give this man the nobel prize of fun

[@RobbyAndrews-j5k]

I haven't even heard it and I already kkow

[@evanrutherfordlazyahole9079]

The only thing I'm missing from this lecture is a goodie bag and shirt coolest professor ever.

[@landonschmitt7117]

Maybe one day we will get to bring our periodic tables and microscopes to dates in Cambridge 😂

[@roshanzebwork2951]

Thanks opencourse ware MIT. Love from Pakistan.

[@wickymonvil9080]

Wicky sends thanks from Midwood Brooklyn

[@VacentViscera]

One could say that Heisenberg... made waves in the scientific community.

[@Zachuchovich9]

Thanl you so much from Mexico, this is helpfully for my tesis, love u so much

[@wordsareuneccesary]

This stuff is so helpful! Thank you guys.

[@roshanzebwork2951]

I just love it.

Can someone tell me why did he choose the transition from 5 to 4 ? ( In first question, was it a whim or a logical choice?)

[@landonschmitt7117]

I forget the exact context, but likely has to do with the element he was working with (given that it seems he generally uses specific elements in his examples). My guess is that the instance described in the example covers a common bond, but don’t quote me on that.

[@WaqasKhan-ym4fo]

Its about wavelength of light that he take for emission in that transition

[@matarrgaye5943]

Thank you so much

[@SweetyLama-v4y]

Ah to the beryllium magical portion... 😅

[@brainstormingsharing1309]

👍👍👍👍👍

[@chengzhiwu7052]

This is pretty much particle physics

[@mahnoorkhan4044]

I can never understand chemistry 😭

[@herminenamakalu4171]

This is mostly physical chemistry... Get through it (Just listen and see what you can understand and move on) and then you can go to topics like acids and bases , equilibrium, organic chem, biochemistry, all which will not zoom into particle physics like this .. Trust me this is like 10% of chemistry, you might enjoy the rest and good luck.. Also , this topic might start to make sense later in your studies..
