The quantitative approach is admirable, but Buffon's assumptions are flawed. Silicate minerals have lower heat conductivity than steels and are better insulators leading to slower cooling rates.Second, the calculations did not incorporate the heating effects of radioactive decay.When this happens in a mineral, the two departing nuclei leave behind a trail of destruction in the crystal lattice. Fission track dating is ideal for samples from recent times back to 100,000,000 years.

Carbon-14 has a relatively short half life of 5,730 years. Beyond 60,000 - 80,000 years, there is too little Carbon-14 left in the sample and this technique cannot be used.

U nuclei undergo fission and the nucleus splits to form two smaller but very energetic nuclei that move away from each other.

Different isotopes of an element have similar chemical properties (undergo similar chemical reactions) but have different physical properties (such as evaporation rates).

However, we can predict what fraction of the parent atoms will decay over a certain amount of time because each radioactive isotope has a constant rate of decay (unaffected by temperature, pressure, or chemical state).

Lyell's extreme form of uniformitarianism would have required a perfect balance between heat production and heat loss.

Kelvin argued that this was physically impossible (the concept is akin to a perpetual motion machine).

) is a Taiwanese romance drama television series based on the original manga novel Absolute Boyfriend by Yuu Watase.

Jiro Wang, member of Taiwanese boy band Fahrenheit played Night Tenjo's role while South Korean actress Ku Hye-sun played Riiko Izawa.

That is, the earth accreted from small, cold chunks of material and then heated up at a later time.

Isotope: A version of an atom that differs from other atoms of the same element only in the number of neutrons.

Chronological Analysis of the Scriptures- Literal interpretation of the scriptures led some people to conclude that the Earth was created approximately 6,000 years old.
