Discovery School - 100 Greatest Discoveries - Physics
1. The Law of Falling Bodies (1604) Galileo Galilei overturns nearly 2,000 years of Aristotelian belief that heavier bodies fall faster than lighter ones by proving that all bodies fall at the same rate.
2. Universal Gravitation (1666) Isaac Newton comes to the conclusion that all objects in the universe, from apples to planets, exert gravitational attraction on each other.
Discovery School - 100 Greatest Discoveries - Genetics
1. Rules of Heredity (1850s) Austrian monk and botanist Gregor Mendel discovers how genetic information is passed down through generations. In experiments performed on pea plants, he notices that characteristics of a plant's offspring, such as height, exhibit recessive and dominant behavior. Mendel's findings are ridiculed during his lifetime and he dies never knowing that he would come to be known as the "father of genetics."
2. Genes Are Located on Chromosomes (1910 – 1920s)
Discovery School - 100 Greatest Discoveries - Evolution
1. K-T Asteroid Theory of Dinosaur Extinction (1980) Walter Alvarez postulates that high levels of iridium found in rock core samples around the world provide evidence that an asteroid impact caused the extinction of dinosaurs. Iridium, a common mineral found in asteroids, was discovered in the clay layer at what is known as the K-T boundary. This layer, at 65 million years, lies between the rocks of the Cretaceous and the Tertiary periods and coincides with the mass extinction of dinosaurs.
2. First Dinosaur Fossils Identified (1820s – 1840s)
