The Arrow of Time - Wonders of the Universe - BBC Two

Professor Brian Cox uses the Perito Moreno glacier in Patagonia, Argentina to help explain the Arrow of Time; a concept that tells us why sequences happen in the order they do.

Huge fan of Brian Cox. He brings a child-like wonder to his content. I always learn and enjoy.

Other than Physics there is one more thing that I like about Brian's videos, the beautiful nature that his videos shares. Just amazing.

It’s official ... I’m obsessed with this brilliant dude & his soothing voice 🥰

I love watching Brian's presentations. It's like watching a kid in a candy store gleefully explain to the workers how candy is made, the hardening point of rock candy and the thermal temperature needed to achieve the crystallization of sugar and corn syrup-how, not enough will result in a somewhat mushy substance whereas too high a temperature can lead to burnt flavor or candy that's too brittle and won't harden properly, how it only takes one or two degrees of temperature to differentiate between the two temperatures, sometimes...and then, out of nowhere a team of Ice Warriors pop up from one of the glaciers and take Prof. Cox captive.

This guy is fantastic. He makes physics accessible by employing these amazing explanations that use our natural world as a prop, albeit a beautiful one. Hats off to the BBC for supporting these sorts of programs. BTW, is there really any need for anyone to disparage or get competitive with other countries about their documentary content? Really?! There are wonderful documentaries made the world over by people just as dedicated and talented as Brian Cox, so let's enjoy them.

Brian Cox is the greatest Teacher, Presenter, Thinker, Soothing voice and friend there is...

Brian: Now thats something you'll never see in reverse
Christopher Nolan: Challenge accepted!

I'm sure it's very scary to hear in person, but on video the sound of the collapsing is pretty soothing, actually. It's like listening to a thunderstorm.

[vitalalive]

What he is telling is actually what we all know and 0have known for a long time now, nothing new to anyone. But the way he gets the message over is simply brilliant and epic.

[moxica]

Such a great series  this and the wonders of the Solar system.    I don't know what I like more, the cinematography, the music or the way he makes everything understandable.

[Primaate]

The definition of Genius - to solve and reveal the complex, simply. Well done BBC and BC.

[debbietimm]

I could listen to his voice explaining the Wonders of
The Universe for eternity 😀 So relaxing!

How is it that I have been watching Brian Cox since I was a kid and now I am a grown man and he hasn't aged a day?

[sinprelic]

this video is about the second law of thermodynamics.

too bad BBC only uploads these snippets!

[AnikHalder]

From what I could make out,
Arrow of Time = Second law of Thermodynamics in terms of entropy(disorder).
In other words,
Universe likes disorder and time moves in direction of entropy increase.

Prof. Brian...Hats off to you as always.

[ezequiels]

I live close to that park, one of the purest airs i ever breathe for sure.

[nicholasmrobinson]

"...we all age..." - do we Brian? I know I do.

[alexanderhopkins]

I went to see that glacier on a warmer sunny day. A fabulous spectacle. 🤓

[PatRedstone]

Love the BBC - thanks for posting this.

I really like your videos, they are great and simple.
I only pick the ones where you are casual.
