How do you use carbon 14 dating list questions ask someone your dating
As for still earlier periods, carbon-14 dating excited scientists (including some climate scientists) largely because it might shed light on human evolution the timing of our development as a species, and how climate changes had affected that.(2) It was especially fascinating to discover that our particular species of humans arose something like 100,000 years ago, no doubt deeply influenced by the ice ages.(3) A few scientists noticed that the techniques might also be helpful for the study of climate itself.
From its origins in Chicago, carbon-14 dating spread rapidly to other centers, for example the grandly named Geochronometric Laboratory at Yale University.
After a creature's death the isotope would slowly decay away over millennia at a fixed rate.
Thus the less of it that remained in an object, in proportion to normal carbon, the older the object was.
Also, the Sun’s own magnetic field varies with the cycle, and that could change the way cosmic particles bombarded the Earth.
For other examples, see the essays on Temperatures from Fossil Shells and Arakawa's Computation Device.
Climate science required the invention and mastery of many difficult techniques.
These had pitfalls, which could lead to controversy.
It was an anxious time for scientists whose reputation for accurate work was on the line.
But what looks like unwelcome noise to one specialist may contain information for another.
The best way to transfer the exacting techniques was in the heads of the scientists themselves, as they moved to a new job.
