Stavros Plakidis
Stavros Plakidis el, Σταύρος Πλακίδης; May 22, 1893 – January 1, 1991) was an astronomer, professor, astrophysicist, mathematician, author, and director of the Astronomical Institute of the National Observatory of Athens and intermittently served as chairman of the National Observatory. He is considered the father of modern astronomy in Greece. Plakidis made systematic observations of variable stars, novae, planets (Mars, Jupiter, Saturn, and Mercury), minor planets, stellar parallaxes, orbits of comets, and double stars, also contributing to the accurate geographic coordinates of the Athens Observatory. Plakidis independently discovered V1500 Cygni several hours after Minoru Honda claimed the find in Japan. Plakidis was born in Constantinople. He attended the University of Athens and became an assistant astronomer at the National Observatory under Demetrios Eginitis eventually traveling to Europe to study in Italy, France, Germany, and England.

Yerkes Observatory
Yerkes Observatory ( ) is an astronomical observatory located in Williams Bay, Wisconsin, United States. The observatory was operated by the University of Chicago Department of Astronomy and Astrophysics from its founding in 1897 to 2018. Ownership was transferred to the non-profit Yerkes Future Foundation (YFF) in May 2020, which began restoration and renovation of the historic building and grounds. Re-opening for public tours and programming began May 27, 2022. The observatory, often called "the birthplace of modern astrophysics," was founded in 1892 by astronomer George Ellery Hale and financed by businessman Charles T. Yerkes. It represented a shift in the thinking about observatories, from their being mere housing for telescopes and observers, to the early-20th-century concept of observation equipment integrated with laboratory space for physics and chemistry analysis. The observatory's main dome houses a doublet lens refracting telescope, the largest refractor ever ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Etymology The word comes from the ''Academy'' in ancient Greece, which derives from the Athenian hero, ''Akademos''. Outside the city walls of Athens, the gymnasium was made famous by Plato as a center of learning. The sacred space, dedicated to the goddess of wisdom, Athena, had formerly been an olive grove, hence the expression "the groves of Academe". In these gardens, the philosopher Plato conversed with followers. Plato developed his sessions into a method of teaching philosophy and in 387 BC, established what is known today as the Old Academy. By extension, ''academia'' has come to mean the accumulation, de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jeans was educated at Merchant Taylors' School, Wilson's Grammar School, Camberwell and Trinity College, Cambridge. As a gifted student, Jeans was counselled to take an aggressive approach to the Cambridge Mathematical Tripos competition: Career Jeans was elected Fellow of Trinity College in October 1901, and taught at Cambridge, but went to Princeton University in 1904 as a professor of applied mathematics. He returned to Cambridge in 1910. He made important contributions in many areas of physics, including quantum theory, the theory of radiation and stellar evolution. His analysis of rotating bodies led him to conclude that Pierre-Simon Laplace's theory that the solar system formed from a single cloud of gas was incorrect, proposing instea ...
