In the 1930s, many pioneers of quantum mechanics, including the famous Niels Bohr, Eugene. Both Eugene Wigner and Werner Heisenberg intuitively believed that there are indeed some new physical laws in living matter. "We must be prepared to discover a new law of physics that is pervasive in biological systems," Schrödinger speculates uncertainly, but he doesn't say what that might be. These questions go beyond mere academic interest.
The core goal of astrobiology is to search for traces of life beyond Earth, but without first defining "life," it's hard to know exactly what to look for. For example, NASA is planning a mission to fly over a plume of material ejected from a crack on the surface of Saturn's moon whatsapp list Enceladus. (Note: Enceladus is a planet known to contain organic molecules, see John Spencer's article in Physics Today, November 2011, p.
38) How to make skeptics Belief that this stream of matter contains life, or detritus of once-living organisms, rather than some form of pre-life matter? Unlike measurements of magnetic fields, scientists lack a life gauge, an indicator instrument that can quantify the progression of chemical mixtures toward known life. Symbol of life 1: carbon metabolism Most astrobiologists focus on finding what we know as "symbols of life." For example, NASA's Viking mission to Mars in the 1970s looked for signs of carbon metabolism as an indicator of life on the surface. Symbol of Life II: Homochirality Another "symbol of life" that has received much attention is homochirality—that is, the existence of only one enantiomer.
