![Physics: Patrice Lebrun works on the detector for the L-3 experiment at CERN, which uses a Bismuth Germanium Oxide (BGO) Crystal. BGO (formula Bi4 Ge3 O12) is used to detect electrons and photons generated by electron- positron collisions in the LEP Collider ring. When an electron or photon enters the crystal, its energy is converted into light. The light is channeled by the crystal to photodiodes, producing an electronic signal. 11, 000 crystals, totaling 12 tons in weight, are used in the detector, measuring the energy and position of the incoming particles at very high resolution. The LEP and L- 3 detector were inaugurated on 13 November 1989. Geneva, Switzerland..CERN is the European centre for particle physics near Geneva. L3 is one of 4 giant particle detectors at the LEP Collider. LEP collides electrons & positrons accelerated to an energy of 50 GeV in a circular tunnel 100m underground & 27km in circumference. L3 is a cylindrical assembly of many types of apparatus - hadron & electromagnetic calorimeters, drift chambers, & a time projection chamber - which fit together like layers of an onion around the point where the particles collide. L3 is a collaboration of 460 physicists from institutions in 13 countries. MODEL RELEASED [1988]](https://m.psecn.photoshelter.com/img-get2/I0000jCzb6JkQqlY/fill=/fit=180x180/I0000jCzb6JkQqlY.jpg)
![Physics: Stanford Linear Accelerator Center (SLAC). Electronics Trailer. J. Chapman checks myriad connections..Stanford Linear Collider (SLC) experiment, Menlo Park, California. With a length of 3km, the Stanford Linear Accelerator is the largest of its kind in the world. The accelerator is used to produce streams of electrons and positrons, which collide at a combined energy of 100 GeV (Giga electron Volts). This massive energy is sufficient to produce Z-zero particles in the collision. The Z-zero is one of the mediators of the weak nuclear force, the force behind radioactive decay, and was first discovered at CERN, Geneva, in 1983. The first Z-zero at SLC was produced on 11 April 1989. [1988]](https://m.psecn.photoshelter.com/img-get2/I0000bLq9F4lmj04/fill=/fit=180x180/I0000bLq9F4lmj04.jpg)

![Alan Weinstein from the Stanford Linear Collider (SLC) experiment, seen with a computer-simulated collision event between an electron and a positron. The SLC produces Z-zero particles by this collision process, which takes place at energies high enough for the electron and positron to annihilate one another, the Z-zero left decaying rapidly into another electron/positron pair or a quark/anti-quark pair. The Z-zero is one of the mediators of the weak nuclear force, the force behind radioactive decay, and was discovered at CERN in 1983. The first Z-zero seen at SLC was detected on 11 April 1989.

![Burton Richter (born 1931), American physicist and director of the Stanford Linear Accelerator Center (SLAC) since 1984. Richter has drawn the letter Z with his torch light, representing the Z-zero particle, one of the mediators of the weak nuclear force. In the 1960s, Richter worked on the Stanford electron storage rings, the first accelerator to collide subatomic particles together. In 1970-72, he directed the building of the SPEAR electron- positron Collider at SLAC, which yielded his discovery of the J/psi particle in 1974. For this work, Richter shared the 1976 Nobel prize in physics with Sam Ting, whose team at Brookhaven had also found the same particle.

The Z-zero is one of the mediators of the weak nuclear force, the force behind radioactive decay, and was discovered at CERN in 1983. The scientist is seen wearing special glasses that enable viewing of computer- generated stereoscopic images of the particle tracks following the collision inside the Large Detector. The first Z-zero seen at SLC was detected on 11 April 1989. MODEL RELEASED [1988]](https://m.psecn.photoshelter.com/img-get2/I0000WrG0PRMxBA8/fill=/fit=180x180/I0000WrG0PRMxBA8.jpg)

![Physics: Samuel C.C. Ting (b.1936), Project Director of the L-3 Detector Experiment at CERN's Large Electron- Positron Collider (LEP). Sam Ting won the 1976 Nobel Prize for physics (shared with Burton Richter), following his discovery of the J/Psi particle at the Brookhaven Laboratory in 1974. The J/Psi particle, and the Psi-prime particle discovered by Richter, implied the existence of two new quarks, Charm and anti-Charm. The L-3 experiment at CERN is designed to search for the fundamental particles of nature and the mechanism by which they receive their mass.

![Micro Technology: Micromechanics: Scanning electron micrograph (SEM) of a mite (Acarimetaseiulus occidentalis) on the surface of a silicon micro-resonator 'chip'. The micro- resonator, or 'semaphore structure', is a product of micromechanics. Micro-resonators are use to make tiny vibration sensors for engineering use. The comb-like detector ends of the micro- resonators are seen here, a thin strand of silicon running from the left detector toward top left is attached to a large resonant mass. The absence of a resonant mass fixed to the right detector indicates a fault in manufacture. To give an idea of scale, the silicon strand is 2 microns thick and 2 microns wide.

![Matthew Jones, wearing 3-D glasses to view computer simulations, from the Stanford Linear Collider (SLC) experiment, seen with a computer-simulated collision event between an electron and a positron. The SLC produces Z-zero particles by this collision process, which takes place at extremely high energies. The Z-zero is one of the mediators of the weak nuclear force, the force behind radioactive decay, and was discovered at CERN in 1983.

![FINAL CONTACT: "GRAVEWATCH". Photo Illustration for the Future of Communication GEO (Germany) Special issue. Fictional Representation and Caption: Interactive gravestones became quite popular in the 21st century. Adding snippets of video of the diseased was quite easy to program since nearly every family had extensively documented their family time with small digital videocams. AI (artificial intelligence) computer programs made conversations with the dead quite easy. These virtual visits to the underworld became passé within a decade however, and graveyard visits became less common. By mid-century many people wanted to insure that their relatives would continue paying their respects, and keeping their memory alive. New technology insured regular visits to the gravesite to pick up a monthly inheritance check issued electronically by a built-in device with wireless connection to the living relative's bank account. Face recognition (and retinal scanners on high-end models) insured that family members were present during the half-hour visits. A pressure pad at the foot of the grave activated the system and after 30 minutes of kneeling at the grave, watching videos or prerecorded messages or admonitions, a message flashed on the screen, indicating that a deposit had been made electronically to their bank account. For the Wright family of Napa, California, there is no other way to collect Uncle Eno's inheritance other than by monthly kneelings.

![Physics: Scientist Hans Hofer at CERN..CERN is the European centre for particle physics near Geneva. L3 is one of 4 giant particle detectors at the LEP Collider. LEP collides electrons & positrons accelerated to an energy of 50 GeV in a circular tunnel 100m underground & 27km in circumference. L3 is a cylindrical assembly of many types of apparatus - hadron & electromagnetic calorimeters, drift chambers, & a time projection chamber - which fit together like layers of an onion around the point where the particles collide. L3 is a collaboration of 460 physicists from institutions in 13 countries..Geneva, Switzerland.
