I'd be in the green slice for sure!
 
I cannot Even Argue With This

There is a deep resonating poetry to this pie chart that speaks to the core of my soul.

The Way the Universe Changed

At the end of the 1800s we finally knew how the universe worked.  Newton’s laws of motion and gravity had been studied for 200 years, and had become the pinnacle of scientific precision.  James Clerk Maxwell had unified the electricity, magnetism and light into a single elegant theory, and Darwin’s theory of evolution explained how living things were connected.  There were still mysteries to be explored, but it seemed the grand structure of the universe was now known.  We lived in a clockwork universe, where cause led to effect, where simple laws governed complex mechanisms.  It was a proven world, as I’ve written about in an earlier series of posts (http://goo.gl/6MVg0).  

 At the time it was generally thought that the nagging mysteries such as the structure of atoms and the structure of the universe would eventually come into the Newtonian fold.  But they didn’t.  Instead, small mysteries became large ones.  The physical laws we thought we understood didn’t always apply.  Understanding atoms and light would require a radically new way of looking at the universe.  Some of the most cherished scientific ideas of precision and determinism would have to be discarded or revised.  Science would undergo a quantum revolution.

Between 1900 and 1950 our understanding of the universe underwent a fundamental shift from a classical, clockwork universe to a quantum universe of probabilities and interactions.  It was a shift that revealed a universe that was larger, younger and more profoundly complex than we had imagined.

This shift can be summarized in six simple equations shown below.  Each one was a step toward modern quantum theory.  

1. The more you have, the faster it is gone.
2. Sometimes you have to make a quantum leap.
3. Every temperature has a color.
4. Light is a wave, except when it’s not.
5. What you observe depends on how you observe it.
6. There are some things you can never know. 

So this week we’ll look at each of these equations, how we came to understand them, and how they changed our view of the universe forever.  We’ll start with the first one tomorrow.  It describes radioactive decay, and it was the first clue that certain effects don’t have a mechanical cause.

The quantum revolution starts tomorrow.

The lectures of Nobel Prize winning physicist Richard Feynman were legendary. Footage of these lectures does exist, but they are most famously preserved in The Feynman Lectures. The three-volume set may be the most popular collection of physics books ever written, and now you can access it online, in its entirety, for free.

Une photo qui permet de bien mesurer la fragilité de notre situation dans l'univers, pour ceux qui en doutaient.

Très bon tuto sur les albums photo G+
 
What a totally helpful article! Thanks for putting this together :)
For the standard size photos (max 2048 pix wide) there is no limit or quota in storing them to Google+. You can also share very large images but full size uploads will count against your Google Drive storage quota. The sharin...
