Professor Jim Al-Khalili Explains What Energy Really Is | Order And Disorder | Spark

The great 19th-century Austrian physicist, Ludwig Boltzmann was one of the most important proponents of the idea that all matter is made of atoms.

Today no one doubts this is true but in Boltzmann's day it was a controversial idea and many of his contemporaries disagreed with him. But Boltzmann used brilliant mathematical arguments to show that many aspects of the world we observe, like the behaviour of heat, can be explained if one accepts that atoms are real.

Thank you, Professor al-Khalili, for years of wonderful physics programs. I have watched/listened to many of them more than once. You're a treasure.

[dedrickhowell]

This professor makes great videos. He explains things clearly and is easy to follow without coming off as condescending.

[HelenaVanCity]

FINALLY! A clear and concise explanation of entropy! A concept I've been struggling to understand for quite some time. And it doesn't surprise me at all that the man who came up with the idea of entropy was suffering from severe depression. Actually, it explains exactly how he got to see it....

I absolutely love Professor Jims videos, at 6o years old being able to watch and enjoy knowledge brought to one in lay mans terms not a period of attempting to memorise facts and figures, or to dive deeper into what really interests one almost makes me want to go back to school. Well done, bravo and thankyou.

Jim is easily a top science educator if not the very best. His demeanor, his enthusiasm, his knowledge, his voice...and so much more!

This Jim and BBC combo is just AWESOME. I wish these dudes would've kept on making docs. Simple, enlightening, captivating, life changing.

Jim Al-Khalili is the righteous heir to the great Carl Sagan. Thank you!

[moamoa]

British really can make very good documentary .
the way they speak very softly without yelling and gesticulating.
In difference with us documentaries you have the presenter speaking loudly like it is a war documentary

[petemchardy]

Your shows are great Jim I've watch them twice you make them really interesting and exciting to watch thanks man

[Urukanguro]

Proffesor Jim Al-Khalili’s use of language as masterful, at least in my brain he has had a profound effect into the understanding of Entropy in the right historical context, Thank you !

[daveroche]

Wow - if only we could have seen this while studying science [biology, chemistry and more to the point - physics] in school, back in the day. Very interesting and fascinating - thank you very much.

[עציוןבקר]

One of the best speakers of the internet. Pity we have to suffer all those non-stop adds

[SamvadSoul]

unfortunately when we were students we did not had such rich presentations to explain complex concepts.

[matispiir]

It's intriguing to think how Boltzmann's bouts of depression and ultimate self-destruction were a manifestation of his profound ideas.

[Jekb]

I really like how you lead up to every point with an overly dramatic monologue and then repeat the 'suspenseful' closing statement two or three times. Also those 45 second establishing shots of the horizon or random guy playing the piano really set the scene nicely before actually getting to the point. Perfect blend of interesting and tedious content, thanks!

[davidrobinson]

Yes, I totally agree with Dedrick Howell, what I would love to do is throttle those that bring the whole thing together and bang in the overpowering back ground noise that can drown out what Prof. Jim Al-Khalili is saying. If you must have it, then tone it down by at least half.

[megacultureshock]

I have traveled the world and back again; served in 3 wars, attended multiple military schools, colleges, and other types of educational venues. But...this gentleman and scholar, always seems to amaze me and bring things to light in which I either forgot, or slept through...lol. Love his teachings.

[bhgtree]

Prof Al-Khalili is the best, theres a lot of great scientific documentaries made, but no one presents them like he does. You can feel his own love of science come through in each programme.

[artdonovandesign]

Prof. Jim Al Khalili's films are the finest science documentaries ever made- anywhere. The collection of his docs are a MUST SEE for anyone who has an interest in the history and mechanics of our world and the universe we all inhabit.

[NorgeDude]

Thank you for talking about Gottfried Leibniz
for a change.
Everyone talks non-stop about Newton - great guy - we all know that.
But Gottfried Leibniz
seems to be an afterthought all the time. He's mentioned as that guy that co-invented Calculus but never anything about the man and his thought process and what he contributed.
Bravo!!!

[Ayjay_]

One of the best documentaries ever produced. I watched it over and over again.
