The Heavens in August, 1903

Mobile Internet from the Heavens

Almost two-thirds of the humankind currently does not have access to the Internet, wired or wireless. We present a Space Internet proposal capable of providing Zetabyte/ month capacity which is equivalent to 200GB/month for 5 Billion users Worldwide. Our proposal is based on deploying thousands of low-cost micro-satellites in Low-Earth Orbit (LEO), each capable of providing Terabit/s data rates...

Neutrinos on Earth and in the heavens

Recent data lead us to a simple and intriguing form of the neutrino mass matrix. In particular, we find solar neutrino oscillations to be nearly maximal (and rule out the small-angle MSW explanation of solar neutrino observations) if relic neutrinos comprise at least one percent of the critical mass density of the universe. 08/98 ∗ Research supported in part by the National Science Foundation u...

Albert Francis Birch August 22 , 1903 - January 30 , 1992 A Biographical Memoir

Francis Birch was a founder of the science of solid earth geophysics. He demonstrated how study of the physics of minerals and rocks could lead, in conjunction with knowledge of seismic structure and geochemical abundances, to an understanding of the constitution of the Earth. Birch obtained, in his Harvard University laboratory, some of the first reliable data for the elasticity (especially at...
