Particles with two heavy quarks are predicted by the Standard Model theory of particle physics, but this is the first time scientists have been able to confirm they exist.
In need of a computer monitor? How about a forklift? Or maybe a sousaphone? If you are working for the US federal government or an approved agency, all this and more is available to your organization—for merely the cost of shipping a few boxes or a crate.
Few facets of nature are more mysterious than the quantum world. Particles that appear and disappear from nothing, interactions governed by probability, and intrinsic uncertainties are enough to baffle even the most experienced scientist.
The amazing properties of spider webs have fascinated scientists for years. Some of the mysteries of the spider's thread (such as the radii and spirals of threads produced by the Nephila pilips spider shown above) are unraveling through the use of synchrotron light sources.
In August 2005 nearly seven hundred physicists and engineers from around the world traveled to the small Rocky Mountain town of Snowmass, Colorado, to advance the planning and design of the proposed International Linear Collider.
Nearly 700 physicists from around the world met in Snowmass, Colorado, to advance plans to create an International Linear Collider, a next generation machine that would answer the most fundamental questions about the universe.
Like climbers assessing a new route before making the ascent, physicists have been looking for footholds on a vertiginous new terrain. These footholds contain important information for trekking to TeV heights (the lofty trillion electron volts energy scales of future colliders).
Believe it or not, most of Fermilab's power comes from pi. Electrical power, that is, as the shape of the lab's power poles is modeled after pi, the symbol for the famous number.
