8.01x - Lect 28 - Hydrostatics, Archimedes' Principle, Bernoulli's Equation

Watching this great lectures series during corona quarantine to enchance my intellect and educate myself in the meantime more.

Why am I watching this? Actually I'm a lecturer in medical school and I had a lecture on blood flow in blood vessels which is based on fluid physics and Bernoulli's rule I couldn't think of anything better to prepare for my lecture than watching your lecture on fluid physics it's a good thing that even doctors are watching your lectures Lot of respect professor From Iraq

Your service and dedication to teach every hungry mind is truly selfless.

Just because of you.... Today I can feel hydrostatics practically.... Great thanks to W. Lewin sir... Love from India 💕💖

Thank you very much Prof. Lewin, I have to take my final oral test in physics for engineering next Monday and after all this years of your lecture being around, you are saving my life as those of many other students ! These should be saved as hsitory of science for years to come !

I think that to understand the pool level problem, it helps being exaggerated. Consider a super dense object, 1 ton with the size of a coin. Now imagine we drop it in a boat that could carry it. Intuitively, the water level would rise significantly to counter the added weight. Now if we drop it in the water, there will be a massive weight relief in the boat and the buoyant force required to keep it floating will be therefore much less. The object has the size of a coin, so the volume of water displaced by it as it sinks is negligible and so is it's buoyancy. The total buoyant force that the water produces will be way less, and so the pool level will drop. As long as the boulder's density is greater than that of water, the same reasoning could be applied.

You are the best teacher ever ! I really love your teaching ! I wanna wish you a long and happy life !! You are someone irreplaceable in my heart ...I wanna meet you so badly and say how much your teachings helped me ! Also I really loved your birthday series 💕 Thank you so much again professor Lewis!

THATS HOW PHYSICS IS TAUGHT.....I AM COMPLETELY AMAZED...... EARLIER I FOUND FLUIDS VERY DIFFICULT TO UNDERSTAND BUT NOW I ENJOYED LEARNING IT IN THIS LECTURE......THE PRACTICAL DEMONSTRATION WERE JUST TOO GOOD.....

Thanks again sir... For the first time I have felt Fluids... Before this I had been thinking that in fluid part there is nothing but puzzles... Now I feel very comfortable in fluids.... Can't pay you against this but infinite respect will always be for you...

Your lectures contain all theory demonstration and application ,looking forward to binge watch all your content

Dr. Lewin's ability to describe and draw complex principles is amazing.

47:28 We can all admire the greatness of the MIT chalks in this shot... no wonder why they sound so satisfying

This is all nice and stuff but the mind blowing part is 0:49

44:55 "That's the reason she couldn't get it up. That's what Bernoulli does to you" - Lewis

Best physics teacher as well as the best physics YouTube I've ever come across. No one else comes even close

In the answer to your waterline of swimming pool question, I think it will go down. When we seperate the stone from the boat, the waterline goes down more than the volume of the stone since the density of the boat is lower than the stone. So when the stone sinks the net effect is a lower waterline.

professor i am from i india, i love to watch your lectures , you explain practically everything. i am in class 10 but i understand everything. it creates me a passion to get phd in physics .thank you professor

How can he make the dotted lines so effortless? Pure skill!

Wow.i enjoyed every sec of this lecture. You are the best.

what a MIND BLOWING lecture
