At the Cerro Paranal Observatory, a laser beam is used to create an artificial star to tune the Very Large Telescope (VLT). The search for exoplanets on which extraterrestrial civilizations could be found is one of the many missions of the VLT. The Kardashev scale (Russian: Шкала́ Кардашёва, romanized: Shkalá Kardashova) is a ...
The 21 grams experiment refers to a study published in 1907 by Duncan MacDougall, a physician from Haverhill, Massachusetts. MacDougall hypothesized that souls have physical weight, and attempted to measure the mass lost by a human when the soul departed the body. MacDougall attempted to measure the mass change of six patients at the moment of ...
Human scale in architecture is deliberately violated: for monumental effect. Buildings, statues, and memorials are constructed in a scale larger than life as a social/cultural signal that the subject matter is also larger than life. One example is the Rodina (Motherland) statue in Volgograd. for aesthetic effect.
The timeline of human evolution outlines the major events in the evolutionary lineage of the modern human species, Homo sapiens, throughout the history of life, beginning some 4 billion years ago down to recent evolution within H. sapiens during and since the Last Glacial Period. It includes brief explanations of the various taxonomic ranks in ...

The anthropic principle, also known as the observation selection effect, is the hypothesis that the range of possible observations that could be made about the universe is limited by the fact that observations are only possible in the type of universe that is capable of developing intelligent life. Proponents of the anthropic principle argue ...
They also showed why lifespan scales as the + 1 ⁄ 4 power and heart rate as the - 1 ⁄ 4 power. Blood flow (+ 3 ⁄ 4) and resistance (-3 ⁄ 4) scale in the same way, leading to blood pressure being constant across species. [37] Hu and Hayton in 2001 discussed whether the basal metabolic rate scale is a 2 ⁄ 3 or 3 ⁄ 4 power of body mass.
