Order & Disorder (2012) User Reviews

A peek into the world of Thermodynamics.

[m-minhaj-7 · 9/10 · 16 January 2013]

The first episode reveal many interesting things about Thermodynamics and throws light on the Second Law of Thermodynamics, Carnot theorem and entropy.For someone who has even a little bit knowledge about thermodynamics it will be very interesting and all the interesting and fascinating facts about the scientists make it more enjoyable.

The second episode is about Information and it's significance in science and technology it very successfully explains what information means and how powerful it can be.The best part was about Maxwell's Demon.

It is nicely presented and use of thermal imagery makes it more interesting.All in all a very nice presentation by BBC.

THE most important film about science you'll ever see

Prof. Al Khalili of the University of Surrey, UK presents us with a science film, the likes of which have no peer. To date, I've watched it over 60 times. Informative. Startling. Unique and undeniably disturbing, "Order and Disorder" deeply plumbs the mysteries of our physical universe in a way that has never been attempted before. In addition to laying bare the fascinating and essential mechanics that drive our universe, the theories and accomplishments of the key figures in science, technology and information distribution are laid out in a perfect and concise historical sequence. Not since the great Alan Burke's "Connections" has there been a show quite as amazing as this.

Although it is an absolute, "Must Watch", be forewarned. The scientific concepts behind Prof. Al Khalili's presentation may very well alter your entire view of our world and our place in the Cosmos.

If there is only one show you'll ever watch about science, I implore you, make it this one. I guarantee you will not disappointed. Thanks for reading! :)

All things must go from order to disorder.

The story starts with a few brave people think about how to use the fire and explosive power to do more work. They imagine machines that run on fire/steam that will do this.

A few of them invent the steam engines but they still don't know the fundamentals that make these machines run. The first principles.

During Napoleonic wars, the French genius, Carnot, humiliated by defeat, vows to understand the reason for Britain's power, the steam engine. He comes up with a simple idea, the more the difference between the hot and cold parts of the machine the more power it has.. The jet engine works at higher temperatures than a car engine and hence can provide more power. Simple and very fundamental idea.

The next question bus how does the heat flow, ie thermodynamics. And why does it only flow in one direction? The hot cup of coffee, if let to its own always looses heat. Why doesn't it happen in reverse. The idea, all things have a tendency to go from order to disorder. From highly concentrated sources of heat, like a hot cup, to a cold state. This is entropy.

How do we measure entropy? Need to go to atomic levels. But we can see, measure them. Crazy idea by, Boltzmann, get comfortable with uncertainty, don't go for exact measurements for atomic levels, go for probabilities.

Probabilities about where the atom would be and the use math to calculate entropy.

The holy grail of energy. Use the most abundant element to create energy. Hydrogen. Make a fusion engine and we won't have to worry, fight wars etc for energy.

The next part is using information to create order and understand the world.

This is good work by the producers and the team.
