What... a bear...? I don't even...

[abhinavjag]

Great lecture!!



[abhinavjag]

Great lecture!!

[CfFial]

How the fuck can i read his text? Even my 3yrs old sister writes better.

[TKnightcrawler]

@CfFial It's cursive...

[sw8741]

ohhh for fucks sake!! who stole my lecture notes damn it!!

[farahhumaira]

love the smiley,lol

re: 41:00 or so (ref to Stockholm), in my humble opinion, Dr. Sadoway deserves a nobel in education for his efforts. I'd also humbly acknowledge Dr. Diamond of Berkeley/Columbia etc, and Dr. Lewin from M.I.T. in similar fashion. Thanks to all of the teachers near and far who so adeptly use YouTube to help us study the sciences and arts. I like to call it UTube :)

a charasmatic man

[hypercarbon]

is the line between grain boundaries the edge of the crystal?

[zapo147]

@hypercarbon crystals form at different nucleation sites within the macrostructure of the crystal you can see with your eyes. There are many different types of defects, but a grain boundary defect is where a two lattices that started growing adjacent to one another meet each other with different orientations. it would be like making two cubes out of legos next to each other but with one on its side. When they meet, they will not be able to bond together well at all. (not at all in that case)

I love this guy's handwriting. I don't understand anything that's being taught (what with passing high school chemistry with the lowest possible B-), but damn. That's some languid penmanship.

[torontobboy21]

he has a freaking good hand writing

[euch27]

Wow, I'm in AP World and my teacher does not really teach us -- as a college class, and I have to admit, It's pretty hard to pace yourself when no one is constantly over you -- at least in 10th grade.

[silvergalena]

Three-oh-nine fun? C'mon. Take five eleven, and learn chemistry.

[TheWesleyAdams]

I'm currently @ West Point. I plan to transfer to MIT in 3 years :]

[amberchiapeilin]

he's handsome, dolce & gabbana model

[lecatie]

I used to think that ALL of the MIT students were as elite as their teachers...

[Clarkyboy21]

this is from a GCSE student.. it seems somewhat easy? i find it interesting :) i like it where he bullys the r-tards at the start

[veyblu7]

Why are they still using blackboards? Whiteboards are the future; plus they don't send shivers down peoples spines....

[ben24by7]

maybe they are trying to retain the traditions.

after all some of the scientists in the WWII work in the same lab before using the same board.

[glenncookiowa1979]

Write more clearly on the black board please.

[deadlywave]

I'm a senior chemist at uni and in my opinion this lecture is pretty boring. His voice is somewhat monotone and i don't find his lecturing style very enthusiastic at all. I'd much rather any of my lectures, there it feels like the lecturer talking is a field marshall.

[Zetune79]

This is SOOO much better than my university. This it what it means to go to a good school I guess.

[AfroPlato]

I like his teaching style.

AP

[achemachew]

Wow he's got a green lasr pointer! it's low ml though.

[SomeLazyDr]

Kind of defeats the point of the lecture with the SEE LECTURE NOTES over the details he goes over. Even if it was copyrighted, just claim fair use.

[rabbitsib]

Takes me back to highschool

[REYDOW]

awesome teacher

[chaser107]

this MIT programe is a brilliant idea.

[sy1234]

Wow, that was awesome.  I actually understood!

[aniya17]

50:12 minutes lol no look
