You can't feel it. Yet the moon's gravitational pull shifts the ground ever so slightly, creating “earth tides” that rhythmically raise and lower the ground.
Plugged into a weatherproof outlet behind SLAC's Test Laboratory, what looks like an oversized green-and-silver go-cart waits with its load of tools and paint supplies.
Who is the grandfather of particle physics? Some might argue he is Otto Mencke, a German philosopher and scientist who received his doctorate from Leipzig University in 1688.
When it comes to training, hiring, and retaining women and members of ethnic minorities, particle physics lags far behind other fields of science. Staffers at three national labs Fermilab, SLAC, and Brookhavenare attacking the problem at every level.
When an earthquake flattened buildings in a number of towns across central Italy, physicists turned their focus from research to rescue and rebuilding.
Gazing into space, scientists wonder why the universe is expanding ever faster. What mysterious force is at work? By recording the light from hundreds of millions of galaxies from a mountaintop in Chile, they hope to find out what's going on.
Helium is the lifeblood of large particle accelerators. As the worlds supply dwindles, the particle physics community must take steps to preserve this precious commodity or learn to live without it.
