An overview of ranges of mass. To help compare different orders of magnitude, the following lists describe various mass levels between 10 −67 kg and 10 52 kg. The least massive thing listed here is a graviton, and the most massive thing is the observable universe.
An antimatter weapon is a theoretically possible device using antimatter as a power source, a propellant, or an explosive for a weapon.Antimatter weapons are currently too costly and unreliable to be viable in warfare, as producing antimatter is enormously expensive (estimated at US$6 billion for every 100 nanograms), the quantities of antimatter generated are very small, and current ...
The God Equation: The Quest for a Theory of Everything is a popular science book by the futurist and physicist Michio Kaku. The book was initially published on April 6, 2021, by Doubleday. [1] [2] The book debuted at number six on The New York Times nonfiction best-seller list for the week ending April 10, 2021. [3]
In fiber optics, mode volume is the number of bound modes that an optical fiber is capable of supporting. [11]The mode volume M is approximately given by and (+), respectively for step-index and power-law index profile fibers, where g is the profile parameter, and V is the normalized frequency, which must be greater than 5 for this approximation to be valid.
The Bethe–Feynman efficiency formula, a simple method for calculating the yield of a fission bomb, [1] was first derived in 1943 after development in 1942. Aspects of the formula are speculated to be secret restricted data .
Tygart said the possibility of Valieva’s grandfather’s medicine “going from a presumably sealed bottle in the bathroom medicine cabinet into her urine at a level of 2.1 nanograms” was a ...
In radiosonde observation, the hypsometric equation can be used to compute the height of a pressure level given the height of a reference pressure level and the mean virtual temperature in between. Then, the newly computed height can be used as a new reference level to compute the height of the next level given the mean virtual temperature in ...
