Lec 5 | MIT 3.091 Introduction to Solid State Chemistry

[Minus0x29a]

Mystery MIT professor, you sir, have taught me more in 10 minutes than two semesters of chemistry with my "Professors". Thank you so much for answering questions I was seriously confused about. My professor couldn't explain to me WHY the Gas Cathode Ray Tube worked, much less the physics formulas at work behind it. Thanks.

How come they didnt try to obscure his notes on the blackboard as well !

[curryeater259]

is it just me or did the chalk board float up at 3:03...

[NTVGAMER123]

:0 im only in grade 5 wow look what i have to do LOL jk

[flowewritharoma]

thanks for watching much more better.

[yoyaya007]

although it s MIT there is some few hotties over there !! cool!

[BigRockMusicFan]

Confusing me too much, I'll stick to my high school 9th grade Physical Science...

[motorolaflex]

I've never heard such a clean explanation of quantum numbers before this. There was a bunch of background information (started maybe 2 lectures back), but it all came together nicely

[ThelemicLaboratory]

I wish all professors were this good. This makes lecturing like like an Art.

[suilan90]

i couldn't have said it better.  this is absolutely incredible.

[noxvet]

Why does he remind me of the G-Man?

[TheAlexRo123]

school sucks*

[treehousemiso]

arent u allowed to ask questions?

[imac50000]

The explanation about the spin might also explain thу UFO phenomena ppl witness... May be it's the scattered electrons they seу in the air? The silver lines are much alike to the saucer, aren't they?

[cshcrazy]

I have no fucking clue what he is talking about

[BuddyNovinski]

What a concept of learning the periodic table! When I took a similar course at Penn State back in 1975-76, I had the false conception that knowing the periodic table was for doctoral students and knowing German as well.

As someone who had learned the pattern of the Gregorian calendar before I even went to school, I certainly should learn the table up to Copernicium! If anything, it should help me avoid Alzheimers' later in life! If I can learn 44 presidents, I certainly can learn this.

[JesusHasMyWholeHeart]

This lecture is phenomenal. Thanks for posting;)

[benkettle]

what a silly comment

[jproducts]

mmm maybe 1/10th of it is highschool maybe more for the BEST highschools

[videoofmike]

quantum numbers were taught at highschool.

[jproducts]

i know i did them the beginning of this semester in grade 12 but the guy said half this lecture is highschool l;evel, but take into account he covered a huge portion of the highschool curriculum in 25 min and this is mostly review to move on to university level stuff, thats why the guy below is wrong.

[videoofmike]

every one have their own opinions, as long as we don't fight, its ok ^_^

[geektoro]

so true

[deefromott]

at 45:50 he says the 47 electrons in Ag net an unequal polarity in their spin, which makes sense... ...but then he goes on and says they are divided in half for spin, which causes the break in the Ag deposit's trace. So which is it?

[hostilechildren]

i dont get it

[Amokvaesenet]

"is something funny going on in Sweden"

Bohr is Danish :)

Great series btw :)

[deefromott]

I think he was referring to Balmer actually

[FennecFoxxx]

bohr worked for a couple of years in sweden, balmer was swiss.

[defjam99b]

He was referring to the Swede Ångström and his cathode-ray experiments which generated the hydrogen spectral lines.

[sugersprinkle]

I love it how all chemistry Teachers have a sense of humor, I found this video so I could relearn the bohr model in a different point of view, but this is way beyond ap chemistry for a high school sophomore, but it was very informational, thank you.

[larrybardo]

this is totally inefficient. he should use the slide and projector instead of writing slowly.

[Andnie]

Yes, it is true that he could do the teaching much faster when only using the teaching.

However the idea is not to do it as fast as possible. It is making the students understand the essentiel points.

This teacher makes the classes interesting, and he is teaching in a very good pace.

I don't know if you ever tried learning difficult stuff by a 50 minuts power-point show.. it's BORING as hell, and you will loose concentration in a few minuts. Making the classes totally worthless.

[highseas123]

Andnie, I totally agree with you. I like this professor's approach to lecturing.

[ffxme]

he briefs things a lot

[tekie07]

Great stuff Thx MIT

[swompdogg]

Fascinating stuff. Much Thanx to Youtube & MIT.

[nhojmabon]

Lectures keep getting more and more interesting. Thankyou so much for the videos.

[StefThomasOne]

I study Chemistry in Italy, this is a really interesting and goog lession

[maxdelbruck]

Great!
