Severe Nuclear Reactor Accidents Likely Every 10 to 20 Years->

Submitted by surveyork
surveyork writes ""Catastrophic nuclear accidents such as the core meltdowns in Chernobyl and Fukushima are more likely to happen than previously assumed. Based on the operating hours of all civil nuclear reactors and the number of nuclear meltdowns that have occurred, scientists at the Max Planck Institute for Chemistry in Mainz have calculated that such events may occur once every 10 to 20 years (based on the current number of reactors) — some 200 times more often than estimated in the past.""

The wavefunction tells you exactly what state a system is in.

Consider a quantum dice. You can perform a roll-operation on it which sets it to a rolled-dice state. You can also perform a result-operation, that also sets the state, each characteristic state of the roll-operation has a value associated with it (1, 2, 3, 4, 5 or 6). You can look at the result without altering the state after the first result is found (it's a projection operator in other words). The first difference with your explanation is that you can roll as many times as you like without altering the state after the first roll. That is, when you roll a quantum dice, it is in a unique state. Rolling it again will not alter its state!

These two operations do not commute. The rolled-state can be written as a superposition of the six result-states - and it keeps that state no matter how many times you re-roll. When you use the result operation, that rolled-state collapses to one of six result-states. Which state it collapses too is random.

The maths of Quantum Mechanics is mostly linear algebra. If it was just practical statistics there wouldn't be so many disagreements about its meaning. Nevertheless, it's QM that agrees with reality.

Another benefit is access to games like Portal 2 without needing to spend at least $100 on an OS. I'm wondering how many people this would benefit though, as a lot of people will either already have Windows, or require it for other software. I'd guess that people with second machines they'd like to play games on would be the biggest beneficiaries.

Everything can be filed under "miscellaneous".
