I read Einstein in Love by Dennis Overbye four years ago.  It was an interesting examination of Einstein’s early life, up through his marriage to Mileva Marić.  Einstein: His Life and Universe was written after the release of Einstein’s archives, and is a more complete biography of the man.  It makes a nice companion volume, revealing much of Einstein’s life in his own words.

I listened to the audio version of this book, read by Edward Herrmann.  He did justice to the German pronounciations, and made listening to the unabridged 21 hours a pleasure.  Having read other biographies of Einstein, I knew the basic outline of his life.  What was interesting about Isaacson’s treatment was his placement of Einstein’s theoretical work into historical context.

For example, I was aware that he knew Marie Curie, but not that he had a long-standing friendship and correspondence with Schrödinger (of cat fame), nor a cordially contentious relationship with Bohr.  I knew of his encouragement of FDR to develop the atom bomb, but not of his pacifism.  And I’m still wrestling with the idea that he was a determinist, and therefore didn’t believe in free will.  On top of all that, he did thought experiments in his head to figure out the properties of light.   And while he won the Nobel Prize for Physics in 1921, it wasn’t for E=mc2 or relativity, but rather for his discovery of the photoelectric effect.

The one required undergraduate course I took was stodgy and didn’t cover anything as modern as Einstein. Despite that, I have a soft spot for the history of science, and this book satisfies it very well.

To celebrate the successful first beam test from CERN’s Large Hadron Collider:

“It’s a fantastic moment,” said LHC project leader Lyn Evans, “we can now look forward to a new era of understanding about the origins and evolution of the universe.”

I can’t wait. :-)

According to this article, the DOE (Department of Energy) announced yesterday that a solar cell had been developed that could convert 40.7% of the sunlight it captured into electricity. Why is that significant? Well, the state of the art on the market today can achieve about 18% at best. So, were talking about more than a 200% increase in efficiency! If Wikipedia’s article on solar energy is correct, then a solar cell farm 265 mi X 265 mi would produce enough electricity to meet all the demands of the US.

… Nobody would miss Nevada, I think.

One reason why I love anthropology:

Archaeologists in Poland have rediscovered what they believe to be the grave of Copernicus, the 16th century astronomer who proposed the theory of heliocentrism, forever removing the earth from the center of our solar system. OK, technically he wasn’t the first to make this claim, Aristotle did, and later Aristarchus reiterated it, but Copernicus is usually given credit for it.

Copernicus was known to have been buried at the Roman Catholic cathedral in the city of Frombork, but the exact location of his grave had been lost. Forensic reconstruction of the skull of a 70-year-old male resembles portraits made of Copernicus, including a broken nose and a scar over the left eye. DNA tests will be performed to confirm the identity.
