They (C14) can decay at any time, spontaneously, well, that is without known reason. 50% decay more or less in 5.7k years. Right?

As in you have something which dissapears, fairly unpredictably, yet within a fixed period of time a given percentage is found to, more or less to remain and dissapear. So that in the given mass a certain percentage dissapears. That time frame is based on an average, therefore it is not certain, but probable.

Carbon dating) is a radiometric dating technique that uses the decay of carbon-14 (14C) to estimate the age of organic materials.

See that's the thing it disappears predictably.

Just like your light bulbs have a life of 10,000 hours but they could burn out at any time.

No one said this was exact. It's a good estimate.

Yes, that's a good analogy. See Granther, a light bulb can blow at any moment, yet its life expectancy is based on the probability of a bulb blowing every 10,000 hours. Thanks jake.

So why is it a good estimate?

Good leaf article. Perhaps it's also worth noting that you need a few grams of material at minimum to have a large enough sample size for carbon dating.

The GOP party doubted math and look what happened to Romney:

This guy Nate predicted the entire outcome of the election based on polls. If I'm not mistaken he was literally right for every electoral college vote.

If you have a good sample size, it will be representative of the entire population.

Math rules life, death and decay.

Don't worry. You'll decay at the same rate as the rest of us.
