Quantum Hologram Sets New Size Record for Writing
The initials for Stanford University are written in electron waves on a piece of copper and projected into a tiny hologram.
Physicists have set a new world record for the smallest writing, with features of letters as small as 0.3 nanometers, or roughly one third of a billionth of a meter. The accomplishment demonstrates that information can be stored more densely than previously thought. The research was conducted at the Stanford Institute for Materials and Energy Sciences, a joint institute of Stanford University and the U.S. Department of Energy's SLAC National Accelerator Laboratory. In achieving this feat, Stanford researchers have reclaimed bragging rights for creating the world’s smallest writing, a distinction the university first gained in 1985 and lost in 1990. The researchers encoded the letters "S" and "U" (as in Stanford University) within the interference patterns formed by quantum electron waves on the surface of a sliver of copper. The wave patterns even project a tiny hologram of the data, which can be viewed with a powerful microscope. Read more...  Several hundred never-before-seen galaxies were

Happy Birthday, Dear Telescope
Nearly 400 years ago, Galileo Galilei pointed a narrow tube with two carefully cut bits of glass on its ends at a pinprick of light in the night sky. He immediately saw that Jupiter has company in its swing around the sun, and single-handedly (but dual-lensedly) invented the field of observational astronomy. To celebrate, the International Astronomical Union is throwing the telescope a year-long birthday party by declaring 2009 the International Year of Astronomy. Public outreach events and activities will be held around the world all year to generate interest and enthusiasm and commemorate astronomy's accomplishments. Read more... New Management Classes from StanfordWhether you are new to management or have held a management position for many years, it is never too late to acquire new management fundamentals and stay on top of current management practices. Stanford is offering some new webinars and management classes this winter. See the full announcement for class dates and registration details. |
