IN THE REVIEW

The Green Universe: A Vision

An illustration of Freeman Dyson’s vision of ‘Noah’s Ark culture’—a space operation in which, ‘sometime in the next few hundred years, biotechnology will have advanced to the point where we can design and breed entire ecologies of living creatures adapted to survive in remote places away from Earth.’ Spacecraft resembling ostrich eggs will bring ‘living seeds with genetic instructions’ to planets, moons, and other ‘suitable places where life could take root.’ A new species of warm-blooded plants, ‘kept warm by sunlight or starlight concentrated onto it by mirrors outside,’ will enable the Noah’s Ark communities to survive.

Beyond Earth: Our Path to a New Home in the Planets

Sometime in the next few hundred years, biotechnology will have advanced to the point where we can design and breed entire ecologies of living creatures adapted to survive in remote places away from Earth. I give the name Noah’s Ark culture to this style of space operation.

The Most Wanted Man in China: My Journey from Scientist to Enemy of the State

In the summer of 1946, as soon as possible after the end of World War II, the Royal Society of London organized a celebration for the three hundredth birthday of Isaac Newton. Newton was born on Christmas Day 1642, laid the foundations of modern physics with his masterpiece, Mathematical Principles …

Einstein: His Space and Times

by Steven Gimbel
Why would anybody want to write another book about Albert Einstein? Why would anybody want to read it? These are two separate questions, but both of them have satisfactory answers. In spite of the large number of books already written about Einstein, there is still room for one more.

Half-Life: The Divided Life of Bruno Pontecorvo, Physicist or Spy

by Frank Close
Why does the American public still consider all spies to be demons? Why does the public make no distinction between technical spies like Julius Rosenberg stealing useful knowledge and tactical spies like Kim Philby destroying human lives? Perhaps it is because the American public is misled by the American secrecy system.

Stardust

Star-forming nebula in the constellation Carina, 7,200 light-years from earth, 2006-2008

When we see things for the first time, the pictures are always a surprise. Nature’s imagination is richer than ours. We imagine things to be simple and Nature makes them complicated. In Expanding Universe, a magnificent selection of pictures taken by cameras on the Hubble Space Telescope, the big surprise is dust.
