Scientists led by Professor Ferenc Krausz have measured the shortest time interval ever recorded, at 100 attoseconds, using tomographic images to record the state of an electron 100 attoseconds after it left the nucleus of an atom. The measurement was achieved using pulses of extreme ultraviolet laser light. The shortest time interval ever measured is […]
Oliver R. Smoot measured the length of the Harvard Bridge in 1958 using his height, which was 5 feet 7 inches, and the bridge was calculated to be 364.4 smoots long. The smoot measurement became a legend and is now used in Google Calculator and Google Earth. MIT offers a “Pirate Certificate” and alumni founded […]
Magnets can be permanent or electromagnets and non-magnets can be ferromagnetic, paramagnetic, or diamagnetic. Magnet strength is measured in gauss and can be affected by various conditions. Rare earth magnets are measured in pull force. Magnet strength decreases as you move away from the surface. A magnet is any object that produces its own magnetic […]
