MODEST MISTRESS. “If no one has yet conceived of such a pattern, it is not because physicists have not tried, but because nature has yet not revealed enough of herself.” https://lnkd.in/dstWYyq5 View in LinkedIn

THE AUTHOR. “Chen Ning Yang, byname Frank Yang, (born September 22, 1922, Hofei, Anhwei, China), Chinese-born American theoretical physicist whose research with Tsung-Dao Lee showed that parity—the symmetry between physical phenomena occurring in right-handed and left-handed coordinate systems—is violated when certain elementary particles decay. Until this discovery it had been assumed by physicists that parity symmetry was as universal a law as the conservation of energy or electric charge. This and other studies in particle physics earned Yang and Lee the Nobel Prize for Physics for 1957.” https://lnkd.in/dYgJtnNW View in LinkedIn

SO ENDS this beautiful story of Pasteur’s chirality experiments of 1848 extending to Yang’s Nobel Prize in 1957. But the story is much more intricate than this and a full documentation of the history of chiral investigations is to be found in the reference below. Humanity has always been aesthetically interested in symmetry, and when scientists can tinker with such objects, there is undoubted joy to be had. https://lnkd.in/dV8y8JCn View in LinkedIn

ALTERNATIVE. “A direct measurement of the gravitational acceleration of antimatter has the potential to show that we live in a “Dirac-Milne” Universe, which could explain cosmological observations without the need for dark matter, dark energy, inflation, or missing antimatter. Such a measurement would also be sensitive to the possible existence of a fifth force.” https://lnkd.in/df5VU2Ug View in LinkedIn

ANTIMATTER FUEL. “An exciting prospect is the use of antimatter as a fuel source due to its ability to convert mass energy to kinetic energy. Upon annihilation of antimatter with matter, tremendous amounts of energy are carried away by charged and neutral particles.” https://lnkd.in/dtWtzEsU View in LinkedIn

SIMULATED FUEL. “By redirecting the charged particles through an exhaust using a non-uniform magnetic field, an impulse can be generated capable of supplying thrust to an engine. Using the Geant 4 simulation toolkit developed by CERN, we simulate this process using a beam core engine design.” https://lnkd.in/dtWtzEsU View in LinkedIn

HIGH VALUE ANTIMATTER FUEL. “A specific impulse of (2.49 ± 0.08) × 10(6) s was determined. This value is significantly higher than specific impulses of current chemical rocket fuels which range from 240 - 400 s.” https://lnkd.in/dtWtzEsU View in LinkedIn

ANTIMATTER ENGINE. “One proposed method for utilizing antimatter as a fuel source is the antimatter beam core engine. The beam core design generates a thrust by redirecting charged particles from an antiproton-proton annihilation through an exhaust using a magnetic field.” https://lnkd.in/dtWtzEsU View in LinkedIn

ACTION AND REACTION. “According to Newtons third law, the change in momentum of the particles being pushed towards the exhaust will generate an equal impulse on the magnetic field in the opposite direction which will in turn be imparted on the entire engine and any vessel connected to the engine.” https://lnkd.in/dtWtzEsU View in LinkedIn
