Hi prof , Are there two forms exist as Matter and Energy or are they both the same(just energy) in the partical level? Thanks and hope you are doing well.
@@lecturesbywalterlewin.they9259 would it be the same if the speed of light was not a constant .By any chance if c=1 then in the above formulas E=m & E=p.In that case wouldn't the momentum and the mass also equal to enery.

Dear Professor Lewin, I have a question about air density when calculating terminal velocity . If a skydiver falls from 30,000 feet and I want to calculate the terminal velocity around the time of impact, would I calculate using the air density (p) around ground level (1.225 kg/m^3) or from the initial 30,000 feet (0.01841 kg/m^3)? Thank you very much.
@@lecturesbywalterlewin.they9259 Thank you very much. I read about Juliane Koepcke who fell 10,000 feet and survived, and Vesna Vulovic from 33,330 feet.
Professor Lewin, I read a article today that stated that they have found the magnetic monopole. I thought you would like to know if you have not seen it already.
@@lecturesbywalterlewin.they9259 I heard a few years ago that a major European car manufacturer made them routinely... I can't remember which, maybe VW? Anyway, I also saw a UA-cam video where someone freezes two magnets that were stuck together, then separated them while frozen. One was north on all sides and the other south on all sides. I reckoned that the other poles were _inside_ these two magnets and they only _looked like_ monopoles. Also, I suspect that thermodynamics has something to do with it, so that they were only temporarily _pseudo_ -monopoles.

Ai generated but beautiful
kis AI se aisa video generate kr skte h pls tell me
@@thealcoholicdr_45basically any AI except the storytellers
Oh thank you its AI? wow
Everyone is beautiful in their own way.. unique and special 💞 ❤️
yes how beautiful
These are indeed beautiful!
Birds are the kites of Nature
Never thought you will use AI😂. But it's very beautiful ❤️.
I have seen different types of Pheasants my co worker grows. His Golden Pheasants are quite remarkable.
They're beautiful.
sir a big salute to you and your life you re my favorite teacher 🙏🙏

Hi prof ,
Are there two forms exist as Matter and Energy or are they both the same(just energy) in the partical level? Thanks and hope you are doing well.
there is matter energy E=gamma*m*c^2 and there is energy, E, in EM radiation (such as light they have no rest mass mut they have momentum p) E=pc
@@lecturesbywalterlewin.they9259 would it be the same if the speed of light was not a constant .By any chance if c=1 then in the above formulas E=m & E=p.In that case wouldn't the momentum and the mass also equal to enery.
impressive ai. mind blown.

So amazing and beautiful

Wonderful, wonderful, wonderful ,

Hi prof,
Light is a particle?
light is both a particle and wave - light has no restmass, but it has momentum, p, and energy E and frequency f. E=pc = hf

If something falls from 30,000 ft its terminal speed, when it hits the ground, ia always about 125 km/hr - also ask google

Ohh God AI is scary and cool at the same time 😅

That's all are Physics ❤
Ai genrations ?
Almost every bird has a crown. Y 🤷😅
Shame they are AI. Their real beauty has been taken from them because of this.
Professor Lewin is "NOT" for the Birds
Beauty of nature
They are not real and made by AI
Indeed Almighty has created the universe full of mysterious entities. This is example an of Perfection !!

Is that first view😊
prof.
Can you proof it that god really doesn't exist??
how the universe started and it all is expanding this all ??
who created your god?
The universe started with the big bang and is expanding ever since
Sir accept christianty please
you may need gods and a religion which is fine - you have that right. But I don't need it (that's also my right)
Ah, that...
Is there any _astrology_ in that religion?

Is there any _astronomy_ ...?
