- Venus (Wikipedia)
Venus is the second planet from the Sun. It is a rocky planet with the densest atmosphere of all the rocky bodies in the Solar System, and the only one with a mass and size that is close to that of its orbital neighbour Earth. Orbiting inferiorly (inside of Earth’s orbit), it appears in Earth’s sky always close to the Sun, as either a “morning star” or an “evening star”. While this is also true for Mercury, Venus appears much more prominently, since it is the third brightest object in Earth’s sky after the Moon and the Sun, appearing brighter than any other star-like classical planet or any fixed star. With such a prominence in Earth’s sky, Venus has historically been a common and important object for humans, in both their cultures and astronomy.
- Enrico Fermi (Wikipedia)
Enrico Fermi (Italian: [enˈriːko ˈfermi]; 29 September 1901 – 28 November 1954) was an Italian and later naturalized American physicist, renowned for being the creator of the world’s first nuclear reactor, the Chicago Pile-1, and a member of the Manhattan Project. He has been called the “architect of the nuclear age” and the “architect of the atomic bomb”. He was one of very few physicists to excel in both theoretical physics and experimental physics. Fermi was awarded the 1938 Nobel Prize in Physics for his work on induced radioactivity by neutron bombardment and for the discovery of transuranium elements. With his colleagues, Fermi filed several patents related to the use of nuclear power, all of which were taken over by the US government. He made significant contributions to the development of statistical mechanics, quantum theory, and nuclear and particle physics.
