That's a huge compliment. Thank you. Every day, I am just trying to live up to MY great physics teacher from high school. Great mentors are so important. Thanks again!
i've spent a lot of time learning on line, i've never been happier with an online teacher. you follow the simple rule of teaching as if you yourself were learning it at the same time. thanks a mill
I failed in my first 2 AP physics 2 tests that led to a BIG thermodynamics test. Then i aced my thermodynamics test. How did that happen? I watched the full playlist for thermodynamics by Doc Schuster. You sir are a genius! Hats off and thank you!
I like the brisk pace and how focused the video was. Your drawings and explanations were also extremely clear and helped me understand the material intuitively. This was far more enjoyable than my usual method of just blindly memorizing formulas. Thank you for this!
Doc, I've been watching your tuts for some time and just wanted to thank you. You've made science easy to understand and it's alot of fun watching. Please continue making tutorials!
Wonderful demonstration of Shear, Doc! By Shearing the book at around 7:40, you demonstrated that to understand shear, a solid rectangular body must be thought of as several very thin planes stacked on top of one another. Shearing a solid body must be thought of as these very planes sliding on one another due to the application of a force. Brilliant! You have a gift for teaching.
You are awesome!! I'm still laughing at this video!! It's great!!.. Do you think you could do one on viscoelasticity (storage modulus, loss modulus, etc)?
awesome explanation you cover in 20 minutes what my teacher spent in 1 hour and didnt understand it at all, with this now I feel more confident for my next week test, thankyou :)
Can you explain the tension equation for elastic springs and strings? T= (lambda)(x) /lo where lambda is the elastic modulus, x is the extension and lo is the original length of the string or spring.
Doc schuster, Thanks very much...I watch your videos to learn physics regularly....one doubt sir, you told there's a negative sign for B. but isn't delta P proportional to delta V ? is this right?---"more the pressure applied, more will be the change in the volume of that bulk thing".....can u guide me through , sir?.. I feel really blessed to learn from your videos .u r great.!
QUESTION since we are exerting force on the rod, we know as we move away from point of application its effect dec so will the force exerted by wall will be equal to F?????
Hey there! just a small question.. how is the shear stress related to the cutting because the particles of paper or something move in (x direction away from each other and how is it parrallael to the surface of it) ?! thanks alot
someone who actually explains something to their students! My teacher just says, THIS EXISTS BECAUSE IT DOES, AND HERE IS OUR ANSWER AFTER PUTTING SOMESTUFF IN OUR HANDY DANDY CALCULATOR. and then stands around for 20 minutes while we are lost completely and he says, NOW READ THE BOOK AND ASK ANY QUESTIONS YOU HAVE he doesn't teach or explain, he doesn't like to grade, and all he does is make the book teach you while he gets food and free soap operas as his students feel mega stressed.
One question Sir! The pressure has the units of newton per square metre; so as the stress do. So, what is the difference between these two. Are they same?
Great video..! # Thumbs Up..! Since you already talk about the Bulk and his friends.. is it possible to talk about how they are used in defining the Compressional and Shear wave velocity...? like why we only have shear Modulus in shear wave velocity equation, but both shear and bulk modulus in compressional wave velocity... :D again, thanks a lot for the video..!
Hello, can I ask a question? in the bulk modulus when pressure change in my textbook "physics for scientist and engineers" it was defined as -delta F / A- but I don't find this reasonable! because when there is a force acting in all directions and the object tend to change his volume, then there is absolutely change in area. I think change in pressure must be like this -delta F/ delta A-. what do you think ?
ahmed markhoos If you mean like, as a balloon is compressed, its surface area decreases, I agree. But I'm not sure just putting a delta there will solve it. The change in area will be small. Really, we need a more careful definition of pressure, I think. Can you find one with a derivative?
I don't know if i didn't listen enough or what but i don't understand enough about modulus of elasticity to answer why the modulus of elasticity would be higher in the {111} direction as opposed to the {100} direction. i'm stumped. :(
my physics text often seems to choose the most complicated and indirect way to explain what could be a relatively simple idea.... I'm sure the guys writing it are really smart but they SUCK at teaching. almost everyone can eventually possess the knowledge but the really hard part is being good sharing it, thanks so much.
sure, serway/vuille college physics- I'm grateful for the variety of examples in there but unfortunate rely heavily on videos online to help solve them! thanks again!
Great explaining :D You're great to listen to, but at the same time, you don't teach fluff. Though, Young's Modulus measures stiffness, I think-toughness is another characteristic.
You're awesome, not me. I'm flipping my high school class around so the punk kids never have to see me lecture in person. That way, we have much more time for labs, demonstrations, and problem solving.
That's a huge compliment. Thank you. Every day, I am just trying to live up to MY great physics teacher from high school. Great mentors are so important. Thanks again!

You are too kind. Really. Thanks for your kindness.

***** You rock, Aakash. Now, if I could only get my local students to watch them...
Doc Schuster I don't see a reason why they shouldn't. You do a wayyyyy better job than the teachers! Keep it up!
I like the brisk pace and how focused the video was. Your drawings and explanations were also extremely clear and helped me understand the material intuitively. This was far more enjoyable than my usual method of just blindly memorizing formulas. Thank you for this!
Thanks for your kind feedback! I have also noticed that many science lessons are TOO SLOW, so I'm doing my best to move stuff along.
Loving the sound effects :)
Hannah Freireich While making dotted lines "chuk-chuk-chuk-chuk"
You are so hilarious and everything is explained so clearly. Awesome!
This guy's one of the best teachers on youtube. Cheers!
Doc, I've been watching your tuts for some time and just wanted to thank you.
You've made science easy to understand and it's alot of fun watching.
Please continue making tutorials!
Thanks! I'll certainly do that. Let me know if you think of something in physics that you'd really like to see.
Wonderful demonstration of Shear, Doc! By Shearing the book at around 7:40, you demonstrated that to understand shear, a solid rectangular body must be thought of as several very thin planes stacked on top of one another. Shearing a solid body must be thought of as these very planes sliding on one another due to the application of a force. Brilliant! You have a gift for teaching.
That's very kind of you! And an excellent perspective on the problem of shear!
I subscribed 5 minutes into this video. Awesome work
You are awesome!! I'm still laughing at this video!! It's great!!.. Do you think you could do one on viscoelasticity (storage modulus, loss modulus, etc)?
This video was great! I barely knew anything about this and now I feel so confident about it.Thanks!
Thank you. Key advice for teachers - steal everything you like. Ultimately, we'll all become better. Let's change the world together!
Is turgor pressure more closely related to toughness?
awesome explanation you cover in 20 minutes what my teacher spent in 1 hour and didnt understand it at all, with this now I feel more confident for my next week test, thankyou :)
I'm happy to help!
Omg! *.* This video is amaizin'!
You remind me exactly of my physics teacher dr.geis in high school - loved his way of teaching
This was so enjoyable 😂😍 thanks for the effort you did a wonderful job there sir :'D
And I thought I solved algebra quickly :-D !!! Super cool and easily understood video ! Great examples too :-D
extremely useful and beneficial to me! THX A LOT XD! looking forward to more modules and topics.
Best Physics teacher ever
This is really well explained! hope one day i can teach as well as you!
life is easy with doc schuster
Very well done! Thank you!
Can you explain the tension equation for elastic springs and strings?
T= (lambda)(x) /lo
where lambda is the elastic modulus, x is the extension and lo is the original length of the string or spring.
This guy is the best,i wish knew him.
Doc schuster, Thanks very much...I watch your videos to learn physics regularly....one doubt sir, you told there's a negative sign for B. but isn't delta P proportional to delta V ? is this right?---"more the pressure applied, more will be the change in the volume of that bulk thing".....can u guide me through , sir?.. I feel really blessed to learn from your videos .u r great.!
in terms of the magnitude of the change, you're right. but not the direction. pressure goes up while volume goes down
but yes, changing pressure more does change volume more
lol I like the way you teach. Although I started looking at the end of your finger after your bloody side story. Like and a sub.
QUESTION

Alan, I have NEVER seen those equations for wave velocities, but I am intrigued. Can you recommend a source where I can learn about them?

The sound fx excite me!😋
What is wrong with me...i was smiling (enjoying) a physics video ??

zephyr2five You've got a substance that is non-isotropic, I imagine.
awesome!
Thank you so much !
Im struggling to do stress and strain and im about to write my exam can you please do more examples hard examples
Many thanks
Excellent words :D
feeling like Rayn Renolds AKA DEADPOOL is conducting the class
my physics text often seems to choose the most complicated and indirect way to explain what could be a relatively simple idea.... I'm sure the guys writing it are really smart but they SUCK at teaching. almost everyone can eventually possess the knowledge but the really hard part is being good sharing it, thanks so much.
Thank you! May I ask who wrote the text? I'll warn my students!
sure, serway/vuille college physics- I'm grateful for the variety of examples in there but unfortunate rely heavily on videos online to help solve them! thanks again!
hahaha...i don't know why, but you remind me of Sheldon from The Big Band Theory.
Great explaining :D
You're great to listen to, but at the same time, you don't teach fluff. Though, Young's Modulus measures stiffness, I think-toughness is another characteristic.
I find it very useful, thankyou xD
Wow you should be a musician! Chuk chuk chuk chuk. Awesome teaching, though.
in conc: ze vurld needs more doc schuster's
Newtons per meter squrr.
-Doc
thnx much
thanks, I'd like to screw up stuffs
Phew - I am way out of my league, here! I hope engineers will find a more knowledgeable teacher once they've seen my naive introduction.
Hi, you're awesome. bye.
Thanks! You seem cool, too!
You're awesome, not me. I'm flipping my high school class around so the punk kids never have to see me lecture in person. That way, we have much more time for labs, demonstrations, and problem solving.
The youtube like buttom sucker has been stressed by my little finger !
HELLO
😂😂😂
Far too annoying to watch for me
