    Is radioactive decay truly random?

    >Since all atoms posses the same physical properties The very first line of the OP's post is wrong. Atoms have different properties. There are different elements and isotopes. They have differing mass, charge, position, velocity, and angular momentum. Then the electrons can be in different...

    So you keep fliping a coin. 50/50 chances

    The standard answer is that its, informally, 2 to the power of -infinity, or zero. The formal answer is its the limit of 2^-n as n approaches infinity. Which is also zero. In non-standard analysis, the answer is not zero ; it differs by a computable amount. The answer is 2^-H, where H is an...

    >According to QM, this is impossible to determine. Yes, QM says it's impossible to determine in the model called QM. I think the Copenhagen interpretation says it's impossible to determine precisely by using a measuring device. (I'm not sure what kinds of particle collections constitiute a...

    Is there such a thing as randomness?

    I'm not sure what you mean by philosophy, but I think you are saying that you don't trust logic. That's quite normal and understandable; people have operated on the basis of irrationality, superstition, and ignorance for millenia. My comment is not strange at all; F=ma is taught all of the...

    >>QM is fundamentaly correct. >calling it correct is going too far. Just like Newton's F=ma, QM is 100% correct - within its limited domain. By "correct", I mean that none of its predictions (usually statistical ones) have been falsified. Not a single one. Unfortunately, QM's domain is...

    There are five 3-pin fan headers (the CPU fan header actually has a 4th pin) on the MB. The CPU fan header and 1 of the other headers cannot be controlled. The other 3 headers are controlled all by one PWM setting. So this mobo is not very flexible :( I don't understand the "Q-Control"...

    Why beat a dead horse, Estrella? The supporting link is clear enough: 1/infinity = 0 "can be made rigorous using the limit concept". If you have more insight to add, perhaps you should let Wolfram know. Yes, I agree. Points are small circles, of infinitesimal size, and they touch on the...

    Yes, it's frustrating, isn't it - being perfect and still not being able to know something! I would call it "ignorance". I don't know what's in the box, but whoever manufactured it or closed it last does know. It's not random. You couldn't be more wrong. Did you know Einstein was a...

    "therefore unknowable, therefore random" You don't understand something, so it must be random. Or maybe it's because of The Gods. Great logic there.

    Eric, I don't think any laboratory experiment has ever revealed an error in QM's predictions. It might not be the truth behind the universe (I agree it's not), but it's certainly accurate enough to build some technology based on it. My dim understanding is that quantum computers work based on...
