	John N. Bahcall - Wikipedia, the free encyclopedia
		Bahcall started his university career at Louisiana State University as a philosophy student on a tennis scholarship, and considered becoming a rabbi.
		He was married to Princeton University professor in astrophysics Neta Bahcall, whom he first met while she was a graduate student at the Weizmann Institute in the 1960s.
		Bahcall's other great contribution was in the development and implementation of the Hubble Telescope, alongside Lyman Spitzer, Jr from the 1970s through to the period after the telescope was launched in 1990.

		Bahcall was born in Shreveport, La., in 1934 and considered becoming a rabbi before choosing science.
		Bahcall said calculations by physicists – including himself – were flawed and that the tiny particles changed their shape.

		John Bahcall: When I got this letter from Ray, the consensus view among scientists who thought about it at all was that stars like our sun shine by burning hydrogen into helium and converting the small amount of extra mass into a lot of extra energy.
		Bahcall: The first experiment that was done after Ray's experiment was done by the Japanese-American collaboration called Kamiokande, which converted a water detector designed to see the decay of the proton into a very sensitive detector of neutrinos from the sun and from supernovae.
		Bahcall: Yes, when their first results came out, I was absolutely thrilled, because they got a result which showed that the flux was definitely less than what I had predicted and that was a confirmation of Ray's result.

	NOVA \| The Ghost Particle \| Case of the Missing Particles \| PBS
		Ray Davis and John Bahcall propose that a study of neutrinos emitted from the sun can show that nuclear fusion—the "burning" of hydrogen nuclei to helium nuclei—is indeed the source of the sun's energy.
		As Bahcall later notes, he has to take account of "a smorgasbord of nuclear reactions at energies where measurements are difficult." He draws upon Hans Bethe's work, including Bethe's estimate of the sun's core temperature.
		Bahcall has calculated that roughly 10 atoms of argon will be produced each week, and Davis is confident he can extract and measure them.

	An Interview with John N. Bahcall
		When Bahcall read the appendix, he saw that laboratory reaction rates had been used for beta decay in stellar interiors, but from his own calculations on beta decay he realized that the rates in stars would be very different from those in the laboratory.
		Bahcall: I wrote a short paper saying that the weak interaction rates being used by astrophysicists could not be correct because the laboratory rates would be changed in stars: ionization and the Pauli principle would play an effect at the high densities inside stars.
		Bahcall: I've written a series of papers in which the goal is to calculate as precisely as possible the conditions in the solar interior.

	Solving the Mystery of the Missing Neutrinos
		Davis is pictured showing Bahcall his newly constructed steel ank (6 meters in diameter, 15 meters long), which contained a large amount of cleaning fluid (40,000 liters) and was used to capture neutrinos from the Sun.
		The abstract of this paper concludes that: "standard solar models predict the properties of the sun more accurately than are required for applications involving solar neutrinos." This conclusion was based upon the agreement to better than 0.1% of the measured sound speeds of the Sun with the values predicted by the standard solar model.

The agreement between the neutrino predictions in this paper and the subsequent measurements by the SNO and Super-Kamiokande experiments is good, well within the quoted theoretical and experimental uncertainties.
