...and time matters

“At the atomic scale, it is never possible to obtain what scientists would traditionally consider to be complete information. Aside from the practical problems, there is an inherent limit on the ability to record information about matter and energy. Understanding conjectural objects requires the willing suspension of disbelief. These objects are fuzzy entities that elude concrete escription, defying commonsense notions of space and time, cause and effect. They aren't the sorts of things you can hold in your hand or play catch with. But whatever its form, information can be measured by bits and therefore described using prime numbers. Measuring the motion freezes its spin in one of the directions, or states, destroying the other possibilities. The destruction of all those different possible spin directions means a lot of information gets lost. But one of the key uses of information theories is helping make efficient use of information. Which is all over the place, even further.”
