  Physics Tip


Viscosity
The property of a liquid that makes it resist flow or any change in the arrangement of its molecules. The higher the viscosity, the "thicker" a liquid seems.
 

  Physics Quote


It is impossible to trap modern physics into predicting anything with perfect determinism because it deals with probabilities from the outset.
    Sir Arthur Eddington (1882 - 1944)

Background

The computers of the early 1950s had several miles of wiring, hundreds of vacuum tubes, and often weighed several tons. Today’s computers operate under the same principles. Data is represented by either a 0 or a 1—the binary system. The binary state is determined by something such as the magnetic state of a part of a disk, or by a pit or groove on a compact disc. For example, the number 123 is expressed as 1111011 in binary. This forms the basis for all of classical computers, completely obeying the laws of classical mechanics, which until Max Planck first introduced the ideas underlying quantum mechanics were the only way we understand how our universe works. With the advent of quantum mechanics, we were able to explore the rules that govern particle interactions on the atomic scale and smaller. More recently, we are learning to control extremely small systems and manipulate them to perform calculations—quantum computing. For decades, the computing industry has kept pace with Moore’s Law, which says processing power will double every 18 months. With classical computers, that has a limit. New technology will have to be introduced at a point, and quantum computers are likely to emerge to continue the trend.

Once a quantum super computer is invented, it may change the physics of the universe to match the computer model invented inside a quantum computer.

If for example that worm holes and time travel are not possible in our universe, or if it can be predicted by a quantum super computer that it is possible, then the phyiscs of the universe will change to match the quantum model inside the computer, and time travel will become possible.

Other then professinail use, what possiable use could the public have for these computers. Unless you see what i see and the internet will be efficently converted to Quatum and use binary pastmen wil be left out. heres my question and email me back, is their really any point to keep introducting newer and newer computers, cause evintily it will hit a wall. If not i am very afriad, cause i refuse to have my body burned seconds after death.
