...messages that signal the price at which investors want to buy or sell. Traders with algorithm-based strategies are jockeying for space at the computer servers closest to stock exchanges in order to shave milliseconds off their trades. This is what the market has come to: the distance an electron travels makes a difference...
George Palade, a pioneer in cell biology, won the 1974 Nobel Prize in Physiology or Medicine for his work in isolating and identifying cell structure. His research, which he conducted along with biologists Albert Claude and Christian de Duve, used electron microscopy to identify the functions of mitochondria (the powerhouse of a cell) and ribosomes (proteinmakers), as well as other cell components. Having emigrated from Romania in 1946, Palade became chairman of the cell-biology department at Yale in 1973 and then the founding dean of scientific affairs at the University of California at San Diego...
...Harvard team has been primarily concerned with the construction and operation of the ATLAS detector, a cylindrical component of the collider engineered to gather data about the particles that emerge when the machine smashes protons together at energies of 14 trillion electron volts, recreating conditions that may have prevailed only a trillionth of a second after the universe’s inception...
...lasers, generated by the reaction of gases such as hydrogen and fluorine, are now considered too unwieldy for space deployment. When they are ground based, their long-wavelength beam would be too ineffective to penetrate the atmosphere and make a missile kill. Today the hottest option is the free- electron laser, generated by the action of electromagnetic fields on electrons. Although it might also be too big to lift into orbit, this laser has a shorter wavelength, which gives it the potential to penetrate the atmosphere from the ground. Whatever ground-based laser weapons are chosen, their beams would have...
...latter is being offered on Feb. 22 in Adams House, part of a new series of free “Life Skills” classes sponsored by the Office of Career Services (OCS). You won’t get academic credit—nor will you use single electron approximation—but you will find out all about radiators...
