How Quantum Suicide Works" ­­A man sits down before a gun, which is pointed at his head. This is no ordinary gun; i­t's rigged to a machine that measures the spin of a quantum particle. Each time the trigger is pulled, the spin of the quantum particle -- or quark -- is measured. Depending on the measurement, the gun will either fire, or it won't. If the quantum particle is measured as spinning in a clockwise motion, the gun will fire. Nervously, the man takes a breath and pulls the trigger. Go back in time to the beginning of the experiment. But, wait. This thought experiment is called quantum suicide.

Albert Einstein: Becoming a Freethinker Taken from: Albert Einstein's Autobiographical Notes Open Court Publishing Company, LaSalle and Chicago, Illinois, 1979. pp 3-5. When I was a fairly precocious young man I became thoroughly impressed with the futility of the hopes and strivings that chase most men restlessly through life. Moreover, I soon discovered the cruelty of that chase, which in those years was much more carefully covered up by hypocrisy and glittering words than is the case today. As the first way out there was religion, which is implanted into every child by way of the traditional education-machine. It is quite clear to me that the religious paradise of youth, which was thus lost, was a first attempt to free myself from the chains of the "merely personal," from an existence dominated by wishes, hopes, and primitive feelings.

Technical School - Engine Turbocharging Basic Theory The advantage of turbocharging is obvious - instead of wasting thermal energy through exhaust, we can make use of such energy to increase engine power. By directing exhaust gas to rotate a turbine, which drives another turbine to pump fresh air into the combustion chambers at a pressure higher than normal atmosphere, a small capacity engine can deliver power comparable with much bigger opponents. Problems - Turbo Lag Turbocharging was first introduced to production car by GM in the early 60s, using in Chevrolet Corvair. Turbo Lag was really the biggest problem preventing the early turbo cars from being accepted as practical. Turbo lag can cause trouble in daily driving. Besides, turbo lag ruins the refinement of a car very much. Porsche’s solution to turbo lag Intercooler The 3.3-litre version 911 Turbo superseded the Turbo 3.0 in 1978. Continuous development During the 80s, turbocharging continued to evolve for better road manner. Light Pressure Turbo (LPT)
