Computer artwork of ATLAS detector at CERN

Virtual reality in physics. Computer-generated wire-frame drawing showing a cut-away view of the ATLAS particle detector to be built at the CERN European particle physics laboratory. The ATLAS experiment will service two accelerator rings; the proposed Large Hadron Collider (dark blue pipe) and the existing Large Electron-Positron ring (grey and yellow). A figure (red) is shown in the lower right for scale. This image was made using CERN's VENUS virtual reality system. It is used to check engineering designs for fit and position before any component is actually manufactured; this process is called virtual prototyping. Compare with space-filled version, T490/163

Sagittal slice through a healthy human brain

Human brain. Slice through a healthy brain, sectioned sagittally in the midline from front (at left) to back. This longitudinal cut exposes major regions of the brain. At top are extensive convolutions of the cerebrum, where higher thought processes occur with voluntary body activity. The cerebellum (centre right) has fine convolutions, is part of the hindbrain, and coordinates muscle movement. The brain contains cavities (ventricles, centre left) which are normally fluid-filled. At centre is the elongated region of the brainstem, a stalk in the lower brain linked to the spinal cord and which controls basic functions like breathing. An adult human brain weighs about 1400 grams
