Understanding Archimedes' principle

The great Greek scientist Archimedes’ “eureka” moment is quite popular. Why did Archimedes get so excited about his thought experiment? What was the concept he deduced while he was taking a bath? More importantly, did Archimedes solve his king’s crown problem using an immersing experiment or a float balance?

Finally!! I understand it now. This is the first time an explanation has included the weight balance - I've always been confused by previous explanations using only volume. Excellent.

the funny thing is you actually have to mix silver with the gold because pure gold dulls quickly without alloying with other metals due to its softness.

I have started learning this concept when I was 15 now at the age of 36 I could say I have got a clear idea.. Thanks

The best animated lesson, perfect teaching

Excellent video on the topic and for the difficult problem of Archimedes, with its historical reference! Good to be used in the teaching and learning process. Bravo!

Finally a video that actually explains what's happening with the weights!! Great video, those 2 explanations are great

[dhanvindpk]

Beautiful Explanation! I did not understand this when I saw other videos. This video cleared all my doubts. Thank you so much!

Great thanks! Presumably if a fluid was used that was sufficiently dense that the crown did not sink, the test could have been completed successfully by comparing the volumes of the displaced fluids, and the balance could have been dispensed with?

I'm wondering how the shape of the object would affect the buoyancy force, since it needs to have the water exerting a pressure ? Since the water needs to actually exert a pression on the surface of the object, surely are there some specific shapes that may affect the effect ?

amazing 👏 It's a wonderful explanation, I'm trying to show it to my classmates at school 🏫

This channel gonna change YouTube algorithm.

From my childhood I listened the "Eureka" story. But now I understood it. Thanks Sabins

[kavyabhatkar]

Thank You so much; I had to write a skit on this topic. This made my work so easy.

Best explanation I've ever heard.

With out watching the video, I would tackle this problem with displacement. Then I would get an amount of pure gold that equals the liquid displacement of the crown. I would then weigh the crown vs the equal amount of pure gold. I'm not sure if there are flaws in my reasoning other than if a heavier substitute over silver was used I.E. lead. I'm curious to see how close I was to the actual method or if I am missing some other variables in my attack method.

Yea I remember my 6th grade science teacher explaining this in 1970 but didn’t go as far as the balance, just the displacement. Always wondered how it could be accurate enough to warrant whacking the crown makers head off. NOW I got it!!!

Best video on the subject. Please make more videos

[amtermin]

Amount of water displaced is dependent on the shape right ? Since the lumped mass and crown is of different shapes, the amount of water displaced will be different and hence the buoyancy force...Then how could he relate purity with buoyancy force ? Can somebody help me to understand this ?

that was the beginning of the perpetual motion machine that runs forever on Superfluids, very good.

Funny how you phrase it at 2:20, as if Archimedes wasn’t alive two millennia before “classical” physicists
