Much of Albert Einstein’s correspondence has been uploaded online via Princeton this past week. And according to io9, astrobiologist David Grinspoon found this gem of a letter from Einstein to Marie Curie.

Gravitational waves, invisible ripples in the fabric of space and time, might be detected by looking for the brightening of stars, researchers say.
These mysterious ripples were first proposed by Albert Einstein as part of his theory of general relativity. The waves’ size depends on the mass of the objects creating them.
“Gravitational waves are emitted by accelerating masses,” said lead study author Barry McKernan, an astrophysicist at the American Museum of Natural History in New York. Really big waves are emitted by really big masses, such as systems containing black holes merging with each other. [See images of gravitational waves]
Scientists have still not made direct observations of gravitational waves, although researchers continue to endeavor to detect them using experiments involving lasers on the ground and in space.
No more Einsteins? Phys.org writes:
Dean Keith Simonton, professor at the University of California, in the journal Nature argues that it’s unlikely mankind will ever produce another Einstein, Newton, Darwin, etc. because, he says, we’ve already discovered all the most basic ideas that describe how the natural world works. New work will involve little more than adding to our knowledge base.
Sadly, the past several decades only offer proof of his assessment. Since the time of Einstein, he says, no one has really come up with anything that would mark them as a giant in the field.
The way modern science is conducted [may be] adding to the problem. Rather than fostering lone wolves, the new paradigm has researchers working together as teams, efficiently marching towards incremental increases in knowledge. That doesn’t leave much room for true insight, a necessary ingredient for genius level discoveries.
“What is the meaning of human life, or of organic life altogether? To answer this question at all implies a religion. Is there any sense then, you ask, in putting it? I answer, the man who regards his own life and that of his fellow-creatures as meaningless is not merely unfortunate but almost disqualified for life.”
So begins Albert Einstein’s The World As I See It, a collection of essays, articles and letters written between 1922 and 1934 focusing on the humane aspect of this scientific genius and revealing him as a man of compassion and wisdom all too aware of the pressing need for science to serve the well-being of humanity.
There are countless documentaries and books discussing Einstein’s enduring legacy to modern science – few are unaware of his contributions to the field of theoretical physics: the general theory of relativity and the E = mc2 formula for mass-energy equivalence are perhaps universally known (if not necessarily understood).… Read the rest
Scientists have been studying Albert Einstein’s dead brain for clues as to his genius. For those of you with the time and tolerance for reading scientific journals, check out the work of Dean Falk, Frederick E. Lepore3 and Adrianne Noe in Brain – A Journal of Neurology. For the rest of us, here’s one of the photographs they studied and below the abstract summary :

Upon his death in 1955, Albert Einstein’s brain was removed, fixed and photographed from multiple angles. It was then sectioned into 240 blocks, and histological slides were prepared. At the time, a roadmap was drawn that illustrates the location within the brain of each block and its associated slides. Here we describe the external gross neuroanatomy of Einstein’s entire cerebral cortex from 14 recently discovered photographs, most of which were taken from unconventional angles. Two of the photographs reveal sulcal patterns of the medial surfaces of the hemispheres, and another shows the neuroanatomy of the right (exposed) insula.
