# Wikipedia carbon 14 dating

If greater likelihood is sought, we could look at the interval 30 \pm 80$years, encompassing two standard deviations, and the likelihood that the half-life of a given sample of Carbon$ will fall in this range is a little over \$ percent.

This task addresses a very important issue about precision in reporting and understanding statements in a realistic scientific context.

Carbon Dating is a controversial dating practice which involves going on dates with lumps of carbon.

What I want to do in this video is kind of introduce you to the idea of, one, how carbon-14 comes about, and how it gets into all living things. They can also be alpha particles, which is the same thing as a helium nucleus. And they're going to come in, and they're going to bump into things in our atmosphere, and they're actually going to form neutrons. And we'll show a neutron with a lowercase n, and a 1 for its mass number. And what's interesting about this is this is constantly being formed in our atmosphere, not in huge quantities, but in reasonable quantities. Because as soon as you die and you get buried under the ground, there's no way for the carbon-14 to become part of your tissue anymore because you're not eating anything with new carbon-14.

And then either later in this video or in future videos we'll talk about how it's actually used to date things, how we use it actually figure out that that bone is 12,000 years old, or that person died 18,000 years ago, whatever it might be. So let me just draw the surface of the Earth like that. So then you have the Earth's atmosphere right over here. And 78%, the most abundant element in our atmosphere is nitrogen. And we don't write anything, because it has no protons down here. And what's interesting here is once you die, you're not going to get any new carbon-14. You can't just say all the carbon-14's on the left are going to decay and all the carbon-14's on the right aren't going to decay in that 5,730 years.

Then I noticed how it had a wide arrange of allotropes, and that did it; I squirted in my pants." Indeed, carbon daters find all the chemical properties of carbon inherently arousing, though the specifics often differ; many prefer it in its diamond form, while others prefer the radioactive isotope of carbon-14, actually finding it sexually arousing to get radiation sickness and die.

Of the world's fetishes, carbon dating is one of the most difficult to have, because sexual satisfaction is very hard to come by.

Here on Earth, Carbon is found in the atmosphere, the soil, the oceans, and in every living creature. C-12, so-named because it has an atomic weight of 12 – is the most common isotope, but it is by no means the only one.
