Carbon dating def
The most commonly used convention in radiocarbon dating. 1950 is the date that the calibration curves were established.
It also predates atmospheric testing of the atom bomb, which significantly upset C12/C14 ratios in the following years.
And if you haven't taken calculus, you can really just skip that video.

So let's do that in this video, just so that all of these variables can become a little bit more concrete.
So let's figure out the general formula for carbon.
These techniques are made possible by sensitive electronic instruments developed in the late twentieth century. A computer program for radiocarbon age calibration.
Both methods rely on the ongoing production of radiocarbon in the upper atmosphere.
The ratios are consistent among species, and the slight (1-3%) differences can also be calculated from the ratio of C) decreases as the radiocarbon decays. Libby determined, one gram of pure carbon should produce about 14 (13.56) radioactive decays per minute.
