...Harvard experiment is contained in a 40-inch box that is open at one end. The box is plated with gold to distribute heat evenly. A cluster of 13 light detectors-much like the electric eye on a camera-keeps the box pointed at the sun. A small telescope mirror collects solar rays coming through the open end of the box and then reflects them onto a diffraction grating, a row of closely-scaped lines that breaks the light up into a spectrum. This spectrum constantly changes as different chemical reactions occur...
...condemning in public statements those who use drugs civil authorities and university officials have poisoned the air too much. I do not question at all the wisdom of condemning the use of drugs in private session with a student, or in group discussion, but it is essential that the cluster of ideas at Harvard about drugs contain the idea that when any student needs care and help he may receive it here without fearing that a Dean will be called first and the doctor will care for him last. The services under this roof exist...
Eventually I did get stoned. Your feet and arms may seem a little cold, and you begin to feel and see things very intensely. Suddenly you wish that everyone would cluster in a small corner of the room because you almost feel that everyone near you is in some magic bubble, whereas the people over in the other part of the room seem very far away. Time slows down in the most felicitous way: an hour can seem like three, but yet I have suddenly seen the sun coming up when I thought it was only one in the morning...
...local city planning students have submitted a new proposal for Expo '76-a cluster of small, simultaneous world's fairs along the East Coast...
...directed development of rocket-launch vehicles from the earliest Redstone. Von Braun helped develop the ablative heat shield, which dissipates the searing heat of reentry by flaking off in harmless fiery pieces. His Huntsville group can also claim credit for what has become known in the space agency as "cluster's last stand"-the grouping of several smaller rockets in a cluster to provide as much thrust as would a single, far larger rocket engine. Saturn 5's first stage, for example, uses five F-1 engines, each generating 1,500,000 lbs. of thrust. Von Braun, perhaps...
