Building 56, the Science Support Building, is scheduled to start construction this fall. It will provide modern, flexible lab space for SLAC researchers that can be adapted to the lab's changing research needs.

A new 12,000-square-foot lab and office building will soon take shape at SLAC.

From the Director: Achievements Bring SLAC Together

by Chi-Chang Kao

Since assuming my new role at SLAC, I’ve spoken several times about what the concept of “one lab” means to me. It’s about breaking down the silos that separate our scientific areas and making sure we have a collective understanding of the amazing science that is taking place here. This week was a great example of the breadth of science at SLAC.

Phrase of the Week: Fermi Acceleration

February 8, 2013 Astrofisica, Astronomia, Astrophysics, Astrophysics & Cosmology, Ciencia, Fisica, Kavli Institute for Particle Astrophysics & Cosmology (KIPAC), Physics, Science, Word/Phrase of the Week |
by Lori Ann White

"Fermi acceleration" is a theorized process by which tiny particles in the vast reaches of space can be accelerated to amazing speeds.

Fermi acceleration, so named because it was first theorized by Italian-American physicist Enrico Fermi in 1949, is one process by which tiny particles in the vast reaches of space

Phrase of the Week: Photometric Redshift

January 11, 2013 Astrofisica, Astronomia, Astrophysics, Astrophysics & Cosmology, Ciencia, Fisica, Physics, Science, Word/Phrase of the Week |
Lori Ann White

Photometric redshifts are an important tool in the ongoing effort to determine just how far away everything is in the universe.

The only proven way to travel in time is to look up into the night sky. Looking at the the most distant objects in the universe is seeing them as they were millions and billions of years ago.

by Lori Ann White

Gamma rays are the most powerful form of electromagnetic radiation. So it might come as a surprise that they can be generated by lightning, right here on Earth.

Phrase of the Week: Coriolis Force

November 2, 2012 Astrofisica, Astronomia, Astrophysics, Astrophysics & Cosmology, Ciencia, Environmental Science, Fisica, Photon Science, Physics, Science |
by Glenn Roberts Jr.

The "Coriolis force" relates to any frame of reference that is rotating, such as the Earth's surface. On Earth, it determines the direction of spin for the spiral pattern in hurricanes, cyclones and tropical storms.

Explain it in 60 Seconds: Gravitational Waves

from symmetry

If you could detect a bowling ball’s gravitational waves, you would know when someone threw the ball – even if you were standing outside the bowling alley.

by Daniel Holz, University of Chicago

Gravitational waves were first predicted by Albert Einstein almost a century ago, but scientists have yet to observe them directly.
