F. Brock Fuller, 82

F. Brock Fuller, emeritus professor of mathematics at the California Institute of Technology (Caltech), died on November 6 at the Rafael Convalescent Hospital in San Rafael, California, four years after being diagnosed with diffuse Lewy body disease. He was 82.

LIGO Listens for Gravitational Echoes of the Birth of the Universe

An investigation by the LIGO Scientific Collaboration and the Virgo Collaboration has significantly advanced our understanding of the early evolution of the universe. Analysis of data taken from 2005 to 2007 sets the most stringent limits yet on the amount of gravitational waves that could have come from the Big Bang in the gravitational wave frequency band where LIGO can observe. The results put new constraints on the details of how the universe looked in its earliest moments.

Caltech Physicists Create First Nanoscale Mass Spectrometer

Using devices millionths of a meter in size, physicists at the California Institute of Technology (Caltech) have developed a technique to determine the mass of a single molecule, in real time.

Mechanics: Nano Meets Quantum

Physicists at Caltech have developed a new tool that can be used to search for quantum effects in an ordinary object.

Uncertainty Principle Used to Detect Entanglement of Photon Shared Among Four Locations

Scientists at Caltech have developed an efficient method to detect entanglement shared among multiple parts of an optical system. They show how entanglement, in the form of beams of light simultaneously propagating along four distinct paths, can be detected with a surprisingly small number of measurements. Entanglement is an essential resource in quantum information science, which is the study of advanced computation and communication based on the laws of quantum mechanics.

Caltech Submillimeter Observatory in Hawaii to be Decommissioned

The California Institute of Technology (Caltech) will begin decommissioning the Caltech Submillimeter Observatory (CSO) in Hawaii. Plans call for the dismantling of the observatory to begin in 2016, with the return of the site to its natural state by 2018.

Caltech Astrophysicist Awarded Dan David Prize

Andrew Lange of Caltech has been awarded the 2009 Dan David Prize along with Paolo De Bernardis of the University La Sapienza in Rome and Paul Richards of the University of California, Berkeley. Lange and De Bernardis have been recognized for leading the BOOMERanG experiment, which provided the first undisputed evidence of the universe's flat geometry. Richards's MAXIMA experiment confirmed the result soon after.

Caltech's Newest Shining Star: The Cahill Center for Astronomy and Astrophysics

The California Institute of Technology (Caltech) scientists who study the outer reaches of space are about to get some space of their own with the official opening of the Cahill Center for Astronomy and Astrophysics.

About Caltech Astronomy

As part of Caltech's Division of Physics, Mathematics and Astronomy, the astronomy department's primary mission is to perform cutting-edge research in astronomy and astrophysics while educating undergraduate and graduate students to become the scientific leaders of tomorrow.

Caltech Researchers Interpret Asymmetry in Early Universe

The Big Bang is widely considered to have obliterated any trace of what came before. Now, astrophysicists at the California Institute of Technology think that their new theoretical interpretation of an imprint from the earliest stages of the universe may also shed light on what came before.
