Lec 30 | MIT 3.091 Introduction to Solid State Chemistry

[baphomet58]

what's his name?

[nkchenjx]

Great teacher!

[jorgejzwu]

beautiful handwriting :)

[qrais]

haha I love this man I swear

[Zobaire90]

What a Legend!

[edithegodfather]

nice suit

[opiated666]

hey did is old... are there no new findings? didnt we needed to rewritt the bio study thing..?

[fvresonanator]

@opiated666 you may need to rewrite your english GCSE.

[opiated666]

@fvresonanator nah im to old for that..and you did understand what i wrott,...and im totalt not english....

[xiuqin24]

Why wasn't INTERNET INVENTED 23 years ago so that I will also be studying what my SCIENCE STREAM classmates were studying as well ??????

My most sincere THANKS to all COMPUTER TECHNOLOGY of America for making EDUCATION AVAILABLE to all students in the world using TECHNOLOGY STUDIES !!!!!!

I hereby SALUTE you all . ON THE MARCH , 1 , 2 , 3 , onwards : March !!!!!!

[sillydillydokieo]

i'm almost done with my degree, and i'm gonna start watching all these videos, at least one a day, to keep things fresh in my mind. these videos are really cool.

[aanandutube]

What this guy is doing - is lighting the fire of magic in the students - the students will lead their own ways. He is just providing the fire - and how !

[smGzscottoh1]

i find his voice hard to understand, :S

what a smart guy!

[Sony1285]

Great Teacher

[1091Floyd21]

I did read somewhere once; something like "that since all nitrate salts are soluble in water, it is not possible to detect the  presence of the nitrate ion by a precipitatiuon reaction." This does not make sense to me as tests can be performed on salts of (chlorides, sulfites, sulfates, carbonates, hydrogencarbonates), by a precipatation reactions, and all of which ARE soluble.

[pichaliiiin]

@1091Floyd21 the thing is that, for all the ions that you named latter, have at least one insoluble salt, for example, AgCl for the chloride, barium sulphate for the sulphate, a lot of salts for the carbonate, and so on. Instead, nitrate doesn't have any insoluble salt, so it's impossible to remove it from a solution or even detecting it using precipitation.

[teledynepost]

Where is Lec 31 & Lec 32?

[MrJas1991]

This guy is great at lecturing.

[RobinHood3000]

Where are you getting your information? MIT totally allows transfer students, haven't you checked their website?

You want to talk arrogant, try looking at the West Coast tech schools.

[TurnerXI]

wow... this is what i learn in high school >.>

[Grundalizer]

I wish I was in this guys class. Is this a freshmen/sophmore course?

[politics105]

the camera person is extremely annoying and moves the camera around. the teacher is on speed and moves around a lot also. hard to pay attention to the information. that is why I always liked reading and not listening to ugly voices moving around like springs.

[oatebuehi]

unfortunately , the video didn't play in my system

oat ebuehi

[scaleshchess]

ahahhaha! I was just thinking of that! maybe open university should colaborate with youtube so we can get a formal piece of gratuation paper after we have studied a few dozens youtube clips!

[123Sparkle456]

wow this professor writes really fast!

[velickodusan]

How old are students who are listening this?

[jacoman1234567]

Ambassador molari ... You are right, but you're still annoying -,-

[AmbassadorMolari]

Why? It's just constructive criticism. Talking about peptide bonds and proteins you cannot omit the crucial resonance structures. A mention of Ramachandran plots also would be very useful.

[vitaliy0]

AmbassadorMolari stop being a stuck up.

[SitoChan]

wooow he writes realy fast XD

[AmbassadorMolari]

Is the term Henderson - Hasselbalch equation unknown in the US?

[AmbassadorMolari]

In German Zwitter means hermaphrodite. In solid state chemistry it would be very nice to show some gel electrophoresis and the connection to the isoelectric point.

[AmbassadorMolari]

Strange, some things he's telling we are teaching in Switzerland to grammar school students. A better depiction of the D - and L- form of amino acids would have been with the help of the Fischer - Projection. In solid state chemistry he could have shown chiral quarz crystals. A nice introduction to chirality is to show "enantiomeric" hop plants, tails of piglets, snail houses and cork screws.

[HPPcello2]

I wish he were my teacher!!

[kstrat88]

Thank you! =)

[Associatedfan]

hey is there lecture 31, and 32?

i need the biochem lectures

thx

[bal20]

Great Lecture, but may I point out the rather brutal mistake at 07:56 when he says oxygen for a hydrogen :-p

[AmbassadorMolari]

He writes amino -NH2 and acid H+, he should have told someting about the carboxylic group -COOH and why it acts as a proton donor (stabilizing effect of mesomery). Mesomery is crucial to the explanation of a peptide bond.

But he's a brilliant showman.

[AmbassadorMolari]

Mesomery is not an English expression, sorry for that. For you it's resonance and resonance structures.

[AmbassadorMolari]

These students are supposedly Americas elite. But we stupid Europeans at their level would ask why can a proton can be abstracted from the carboxylic group but not from the amino group the polarization is similar given the electronegativities of nitrogen and oxygen.

[chris9986]

Americas elite don't necessarily go to MIT. Most top students go where they can get scholarship money first. However, I would say that US medical schools no matter the name have elite students though. If you are talking elite as in money, then MIT is a good place for science. I know a guy who went to MIT who was pretty bright. I get good grades myself, but don't like my school because there are a lot of foreign professors, and some of them are very hard to understand.

[slashingraven]

I did a YT search for "Don't Let's Start". How is this the first search result?

[v01dad3pt]

nevermind.

[nicholaslab868]

it was sooooooooooooooooooooooooooo boring

[wasdom01]

Great lecture. This sort of thing really helps me with my own uni studies. I like this guys lecture style. Powerpoint rules presentations in my subjects, but I think having him write things down (neatly!) might actually slow things down enough to make it more digestable. Interesting subject matter too!

[bal20]

I agree totally

[IgorSavtchenko]

Because I will never be able to go to MIT, mentally and financially, this youTube channel is the second best. Thank you!

[bal20]

Isn't it a very fortunate insight!.. we are lucky

[hxly2]

Excellent course and thanks for making it available to the public. But why is it called Solid State Chemistry when it's actually Biochemistry?

[sikory]

I believe it's a course that everyone who studies chemistry should take(or an equivalent like principles of chemical science) and for that reason they also have to put some stuff in that's not solid state chemistry, but this course does contain more SSC than the other courses

[quantiseduniverse]

A wonderful lecture. Thanks for posting.

[NodeRanvier]

This was very helpful, thank you.

[Associatedfan]

what happened to lectures 31 to 33??

[LiiMuRi]

They can be found from the OCW website (on right), but they are audio only. It's a shame, Lec 32 would have had batteries and fuel cells.
