Dating of fossils by scientists

However, it is also used to determine ages of rocks, plants, trees, etc. When the sun’s rays reach them, a few of these particles turn into carbon 14 (a radioactive carbon).

He defined elements, compounds, and mixtures; and he discovered the first gas law – Boyle’s Law.

Produced the best star catalog that had ever been compiled and measured the orbit of Mars with unprecedented accuracy, paving the way for Kepler’s laws of planetary motion and Newton’s law of gravity.

The unit of electrical inductance is named in his honor.

Discovered radio waves, proving James Clerk Maxwell’s theory of electromagnetism; discovered the photoelectric effect, providing a clue to the existence of the quantum world. Famed for his 23 problems, Hilbert propelled mathematics to new heights.

The amount of carbon-14 gradually decreases through radioactive beta decay with a half-life of 5,730 years.

So, scientists can estimate the age of the fossil by looking at the level of decay in its radioactive carbon.

At high geomagnetic latitudes, the carbon-14 spreads evenly throughout the atmosphere and reacts with oxygen to form carbon dioxide.

Carbon dioxide also permeates the oceans, dissolving in the water.

He replaced Euclid’s axioms dating from 2,000 years earlier, allowing the unification of 2D and 3D geometry; he created Hilbert Space, now essential in advanced physical science.

One of antiquity’s greatest scientists: founded the mathematical discipline of trigonometry; measured the earth-moon distance accurately; discovered the precession of the equinoxes; documented the positions and magnitudes of over 850 stars; his combinatorics work was unequalled until 1870.

Founded quantum statistics with an alternative derivation of Planck’s radiation law based on the idea that light photons of the same color are indistinguishable from one another – particles such as this are known as bosons.
