You did in 16 minutes what my lecturer couldn't do in a week, thank you so much for the awesome vid!

[@yazan13]

Agree.

[@jasejoe8117]

@KAOUTHER ACHOURI i think it cuz we can't focus on teacher during class lol

[@g_rr_tt]

a week? a my university this was explained in a 1.5 hour lecture...

[@ahmedmuayad2013]

would someone plz give this great woman a cup of water!! thank you very much for the video

[@Justaguy397]

for real... all that freaking smacking

[@qdkqzdkmklzkmld9779]

lmfao

[@germanautos4570]

hahahhaha, your comment just ruined the rest of the video for me

[@shibangachitendwe5237]

😂😂😂😂😂

[@nicknogalo1535]

Hahahaha

[@lanakamal8369]

Seriously people? Do you know how much great information this video contain? I have to read the whole chapter to understand half of what she explains and you all are complaining about her voice instead of thanking her, what's wrong with you, your instructors get a shit load of money and don't even teach you shit, while she's doing it for free!

[@katherinerioux6176]

I totally agree… I honestly can’t wrap my head around how entitled people are lol. They come to a video someone posted for free and criticize everything.

[@thesuperblaze9567]

This video and how she calmly just explains and shows it to us is phenomenal.

[@ilterstellar]

I came for engineering lesson but why is that ASMR ? :D

[@usopphammergataling3910]

She doing the naughty

[@panashemuyembe3466]

9 years down the line but you still have made my life wonderful with this video. Thank you

[@MissussBitchy]

THANK YOU for this wonderful tutorial, for the slides on Slide Share, and for the Quiz at Quizlet. I'm a dentistry student, and we have a materials module. Our prof was incoherently rambling about this cooling phase equilibrium diagram for two whole weeks (4 hours of lectures), and his lecture notes are totally incomprehensible. But this wonderful video explains it all in 16 minutes, clear and to the point. I'm very grateful to you for your efforts ! All the best ! XX

[@akro286]

This was by far the most descriptive and clear video about phase diagrams I've seen! My finals are coming up and i just couldn't understand phase diagrams.. Well, not anymore. Thank you very much!

[@arkichallam2812]

this is what we called the perfect way of making us to understand, thank you very much Miss, the presenter of the video. I wish all Physics lectures to be in this way of teaching, in simple way and perfect.

[@hassantarek6872]

I usually do not comment on KZbin videos, but I just wanted to say thank you and after more than 7 years this video u made is still helping students. You were great, thanks.

[@shemaiahbarton7883]

Thank you so much! This 16 min. video helped more than all 3 lectures my professor gave on the topic! Your an amazing teacher!

[@designateddavethatisntcall2294]

I usually don't comment on any youtube videos but I just wanted to say thank you so much for all the explanation in this and the next videos, it is all perfectly explained and thanks to you I finally get this part of the course :) Thank you so much!!

[@jakmcgann630]

Best video I have found on this subject, looking at comments and ridiculous people moaning about excess background noise etc how pathetic appreciate the video for how easy and understandable it makes the subject matter.

[@BenRickProductions]

I was struggling so much with this until you mentioned the whole solubility limit thing. That just made everything click and was not mentioned in my book for some reason. Thank you so much for this amazing video.

[@brielleibe8503]

Thank you for your help! Everything was simple, organized, and easy to understand!

[@AtticusEluih]

Thank-you so much for taking the time to make these videos. I sincerely appreciate it!

[@maxgoris7568]

Whoever made this, thank you. Teaching stuff in 16 minutes that our school does in 2 hours.

[@yazan13]

I'm going to pass my final today because of your heroic work 8 years ago, THANK YOU!

[@MaterialsConcepts]

Thanks for watching the video! We're going to start working on phase transformations next spring.

[@Jezebel1115]

Professor, Thank you!!! I think if I watch this video a couple more times I will understand "scary" phase diagrams!!!

[@calebtshionza5889]

Gratitude from Africa, I am a first engineering student and the phase diagrams were killing. So thank you for making it so simple.

[@muhammadrifqifauziwijaya8230]

I would like to say thanks to the one who makes this video. It really helps me to understand the phase diagram

[@roykhaled3189]

Now that's how to explain phase diagrams. Practically saved me for finals. Thanks a lot!!

[@atxgurl00]

Thank you so so much! This cleared up a lot of questions I had before my Materials test tomorrow!

[@hassantarek6872]

What did u do?, My material exam will be tomorrow

[@bowaleed3900]

this video still the best in KZbin even after 8 years , it so sad that you won't continue explaining MC

[@efo700]

Would just like to give you a huge thanks. Got an A on my exam in Materials Science and Engineering thanks to your videos.

[@ananias-]

simply supper n awesome wiz clear n lovly voice! I expended long hrs in class, but acquired v.few concept...Tnx a lot for all ur concern

[@MigdaliaMasqueradeee]

thank you for making this video! very straight forward and helped a lot

[@MaterialsConcepts]

Thanks for watching the video! We will be working on a ceramics video next spring.

[@johncantor1639]

after 10 years this video still very useful , i opened it just to understand this graph for FE-Civil Exam , thanks

[@orderphonix24]

Thank you so much for all of the 5 videos, they were extremely useful!

[@RangiRuambil]

My lecturer honestly he is a theif in my university I can say it ,because he didn't lecture like this to me. Instead he introduced the topic and run away every time. Thank you very much Madam for the wonderful explanation...

[@molelatembo360]

I completely forgot how to deal with the lever rule buta after I watched this video I am able to recall everything. Thank you for the good explanation ✌🏾✌🏾

[@divineconfetti649]

Just learned 2 hours of lecture from a 16 minute video thank you so much

[@fiona.e1026]

Because of this channel I have took 85 over 1pp in my midterm. Thank you so much

[@isaacmoore6992]

Thanks for this, both my professor and the book neglected to mention that we were finding the chemical composition of the phase and not just the phase fraction, i assumed 100% concentrations as my prof never told me otherwise=)

[@MrPureownage123]

Am about to write a midterm tomorrow for my material science class. Because of you i'm probably gonna pass now. thank you

[@mertdemirel5134]

The video is the most efficient explanation about this topic on youtube, thank you very much!

[@PythonDelta]

Simple and to the point, very nice! Thanks a lot for this, it was really informative.

[@UmmerSiyad]

Great explanation! Understood the concept clearly, thanks a lot!

[@burcmm]

I passed an exam with the help of your lecture, thank you so much.

[@flyboiii28]

I have a huge test on this stuff. You explained it much better than my professor! Thank you!

[@Ridgestewart]

Very helpful. More insightful than my actual Materials professor.

[@nikhilsrivastava1519]

Someone please give this women a medal. _/\_

[@ACM86]

You are very good at explaining things clearly... Thanks.

[@MrAyushman]

Great video. Understood the concepts in the 1st time, watching it for the 5th time for the voice.

[@arturcunha1874]

Thank you so much I have 3 exams next week and learning this by myself has been a strugle this made it way easier

[@someonesomeone4026]

today is the deadline and finally I'm getting it, god bless your heart

[@kilo3007]

Great video even years later. Well done

[@seanallen8137]

Literally the most helpful vid I have found on this stuff!!!

[@minindupanditha8651]

Appreciate this. you just summarised a whole lecture💯 Was Very useful

[@Reko000]

Keep water beside you while talking and keep taking deep breaths, relieves anxiety. I love your teaching, keep it up.

[@benjamintan90s]

awesome ! Your explanation is clear and straight to the point!

[@n.r.krishna995]

Very good detailed explanation in short time . Thank you for your efforts.

[@tweteybird7]

THIS VIDEO IS AWESOME!!!! I GIVE A BIG THANK YOU TO THE AUTHOR OF THIS VIDEO!!!!

[@mfundomkhungo9741]

You simplified the calculations. I now understand, i no longer need to cram the formula, so Thanks a lot. :-*

[@zaccooper9557]

Excellent video! Quick and easy to understand.

[@cao0002]

You have explained to me in 5 minutes what my proffessor can't explain in an hour, thank you

[@madeinindia20]

Thank you so much for this awesome demonstration!

[@lovelife823]

Thanks for this nice demonstration, it's so clever and made phase diagrams easier to handle

[@Omg123heyitsme]

Thank you so much for this video! I honestly would have failed my exam if it wasn't for your content!

[@DanielSchaefer01]

So unbelievably helpful. Thanks!!

[@kr4bz]

I swear, you are better than my lecturer...although I must say I haven't really been in class all that much, thanks x 9000!

[@stephanbotes5865]

Thank you so much!!! This video helped me a lot. Thank you so much for the trouble you went through.

[@cabelguy012]

I thought your video was very clear and well organized. Drawing on the phase diagram made it easy to follow your steps one-by-one. A way to improve future videos would be to talk about what the two phase regions physical look like as you move left to right. Such as at the 40% wt Sn the microstructure would have 2/3 solid B and 1/3 solid A. And as you move left or right you add or subtract more A and B respectively. Visualizing what it would physically look like is what helped me grasp phase diagrams.

[@thesuperbruce]

Clear, concise and quick. Thank you very much.

[@shubhamanand4721]

Thank you very much for these video series they are great and your sweet voice adds to its effectiveness

[@byronnaidoo7843]

By far the best explanation I've found

[@ItachiUchiha-qv4xv]

Thank you. This video really helped me. My exam is tomorrow so I know now I'll definitely score good.

[@hemkumargarg]

Thanks for explaining such a complicated topic in such a simple language.

[@nadashedid8922]

You're just perfect .. Thank you !!!!

[@shukriahmed3464]

This was so well explained . Thank you so much .

[@divyanshsharma8401]

This is amazing it just summed up whole chapter in 16mins :-)

[@harith8142]

My lect explaining abt this was good enough but it is just me, a silly student who always want to understand but then out of the way from focus for study to being in my 'own world' where the dreams came true. So, ur vid was so helpful for me to understand what have i learn, and trust me before i watch this im just get 15% knowledge for this topic but you just make a wow things, now im 70-80 know how to handle this !!!

[@kellymoses4378]

Thank you very much..Very interesting. I have learn something that I have been struggling with for the past couple of months..Waiting for your next video..oh yeah pls give this woman a cup of water she derseves it

[@justinlarkins2496]

You are legit the reason I’m passing this module😂😂

[@alvaro7003]

thanks a lot. I have a final tomorrow and you just made everything so simple. :)

[@pacoreza10]

Hey. I thanks you for this video. This clip was very useful to me. Just a question: Please, could you tell me what software did you use to make the diagrams?

[@jacobheth]

God bless you woman... excellent vid.

[@MiranDabare]

Wow for the lesson' and a big WOW for the voice! Really good tutorial. Thanks

[@nomphumelelofunde1317]

God bless you! now I can write my exam confidently

[@aymanalzahrani7193]

thanks for this helpful videos. I got couple of questions . First for the phase present for you the both were at the same region , how about if the temperature is at 220 c. Shall we right both locations ?

[@zangetsu1597]

Thanks a lot for explaining to me something I should have learned more efficiently in class.

[@jasonmemba5243]

Wow! Teaching is a calling. Awesome!

[@adamallford2400]

the comments section here is disgusting. This is a clear, concise, well structured FREE lecture on a technical topic that makes more sense than most lectures on the same topic, and people are hung up on the slightest imperfection in her voice, or making lewd comments about the speaker. I bet most of you wouldn't make these comments if it was a man presenting in exactly the same way with the same imperfections. truly is sad that some of you are so threatened by an intelligent woman you have to hide behind your keyboards and pick something to pieces to make yourself feel better about your insecurity.

[@jjustaddsun]

Not so triggered by those comments but totally agree. Its about the information, not how she present it, gal could be nervous

[@AtPrEd]

You are one coin side of the same problem.

[@RooMRami]

Thank you for making this easier!

[@ahmednabeel7597]

It's very useful , thank you .

[@rodneyngwenya8435]

Awesome stuff. I love your voice even more

[@abdul-kareem4429]

Thanks a bunch! I have my exam tomorrow. Still, this video has been really, really, really helpful.

[@alejandroromero1372]

extremely informative!!!! thank you!!

[@David-jw7xl]

Thank you for that clear and concise explanation, it really helped me a lot as I couldn't understand the crap from my book.. :)

[@DUKSHVNKL]

its kusima from orphan black!! thank you. loved it

[@yacineoudaoud7899]

awesome im ready for my quiz ! someone give her a glass of water

[@qdkqzdkmklzkmld9779]

i failed the test LOL

[@renatawaithe3311]

i REALLLLY appreciate yur channel... :) im a first year student. thanks for the help!!! :)

[@mthom100]

Please dont pay attention to the stupid comments. Keep up the great work!! you're making a difference!!!

[@aliqan6258]

great video, i watched it like 5 times tnx for sharing your education

[@1kilohawk]

Excellent video, you explained it far better than the Dr im paying to explain it to me!! But BOOST YOUR MIDS PEOPLE!

[@saqibabbasi116]

This lady has Amazing skills of teaching.

[@serisingh]

I wish my professor was as god at explaining this as this lady in the video is! Dang, It is so much easier when she explains it!
