How does it arise, why does it take different forms, why does it vary in degree across societies, what are the components that add up to gender inequality, how do various institutions and practices contribute to it, and how does it change?
The course will emphasize the history of gender inequality in the United States.
C dating, thermoluminescence is related to radioactive decay.
Thermoluminescence is produced by radioactive decay particles (electrons), trapped in mineral grains.
Heating the mineral (or exposure to light) releases electrons, and produces a flash of light, setting the clock to 0 (maybe only partial).
Thereafter, luminescence accumulation is proportional to age.
1- Sample preparation area: The samples are prepared following standard protocols that are specific to the kind of material dated.
All the equipments needed for an optimal sample preparation are available: circular saws, dentist drill, agate mortar, sieves…
Researchers employing this method measure the amount of trapped uranium in flowstone deposits and compare it to an assumed flowstone deposition rate, deriving an assumed absolute age of the cave flowstone.
Why has lead researcher Lee Berger, who is touring the world touting these fossils, not performed even one of several standard dating methods for fossils?
