	Bolyai biography
		Bolyai was posted to Arad in 1826 and there he found that Captain Wolther von Eckwehr, one of his old teachers of mathematics from the Academy in Vienna, was also stationed.
		Bolyai gave him a draft of the materials which he was writing on the theory of geometry, probably because he hoped for some constructive comments from him.
		It seems that Farkas Bolyai did not approve of Rozália, was unhappy about his son's financial position, was unhappy that the family estate at Domáld was not being properly cared for, and was unhappy that his son was damaging his good name for Farkas was a highly respected member of the community.

	Bolyai (crater) Information
		Bolyai is an old lunar crater that is located in the southern hemisphere on the far side of the Moon.
		To the southeast of Bolyai is Eötvös crater, and to the north is Neujmin crater.
		This crater has been heavily eroded and worn by subsequent impacts, leaving only a deformed remnant of the original rim that is overlaid by a multitude of lesser craters.

	Bolyai
		Bolyai was born in Hungary (although the town Kolozsvár is now renamed Cluj and is in Romania).
		By the time Bolyai was 13, he had mastered the calculus and other forms of analytical mechanics, his father Farkas Bolyai giving him instruction.
		Bolyai was plagued with a fever which frequently disabled him and in 1833 he was pensioned off from his army career.

	Janos Bolyai
		Janos Bolyai was born Dec 12, 1802 in
		Farkas Bolyai had himself been busy working on what would be the most important work of his lifetime, the Tentamen – his presentation of the elements of mathematics.
		The significance of the work by Janos Bolyai in the development of non-Euclidean geometry, as well as that of Gauss and Lobachevsky, was not fully realized and appreciated until decades later.

		JÃ¡nos Bolyai (December 15, 1802 â“ January 27, 1860) was a Hungarian mathematician, down pat for her pest in non-Euclidean geometry.
		Bolyai was intrinsic in KolozsvÃ¡r, Transylvania (today Cluj-Napoca, Romania), the son of a well-known mathematician, Farkas Bolyai.
		Bolyai's pest was disseminated in 1832 as an appendix to a mathematics textbook by her father.

	THE CONTRIBUTION OF HUNGARIANS TO UNIVERSAL CULTURE
		His firstmathematics tutor was his father Farkas Bolyai (1775-1856), whoduring his studies in Gottinga was accepted by Gauss, the 'princeof mathematics', as a friend, and who introduced his son to theproblem of parallels, a concept that had remained unsolved formore than 2,000 years.
		Bolyai's mathematical work was not limited to his geometric examinations,and his scientific work to mathematics.
		Bolyai's name is immortalized by a crater on the Moon, and rightnext to him there is a crater named after Eötvös too,a fine symbol.

		Bolyai's mathematical work was not limited to his geometric examinations and his scientific work to mathematics.
		This was understood by Bolyai and later by Kármán, Neumann and their great fellow scientists when they helped the state leaderships with their advice, and this was understood by those heads of state who presented the highest decorations to the Hungarian pioneers of a new world era.

		His friend Farkas (Wolfgang) Bolyai (with whom Gauss had sworn "brotherhood and the banner of truth" as a student) had tried in vain for many years to prove the parallel postulate from Euclid's other axioms of geometry.
		Bolyai's son, János Bolyai, discovered non-Euclidean geometry in 1829; his work was published in 1832.
		The survey of Hanover later led to the development of the Gaussian distribution, also known as the normal distribution, for describing measurement errors.

	Bolyai
		By the tender age of 13, Bolyai had developed a mastership of calculus and other sorts of analytical mathematics and mechanics.
		Mainly, Janos was taught by his father, Farkas Bolyai, who gave his son unparalleled instruction.
		Tormented by a horendous fever, Bolyai was pensioned from the army in 1833 and died on January 27, 1860.

	A CATASTROPHICAL SCENARIO FOR DISCONTINUITIES IN HUMAN HISTORY (Site not responding. Last check: 2007-10-15)
		A study by Hartmann [22, 23] of the ages of the craters in the solar system, particularly in the Moon, whose craters are attributed to impacts with Apollo-like objects, has shown that, apart from superimposed fluctuations, the rate of cratering has been essentially constant in the last three billion years.
		It is a complex type crater, with a diameter of 45 km and a central uplift 1.8 km high and 11.5 km large.
		Disregarding the possibility that the crater is yet undetected (it could lie on a submerged continental shelf or under Amazonian jungle where erosion by rain is heavy) we can consider the hypothesis that the impact was in the super Tunguska class (a body of a few hundred meters diameter, getting possibly fragmented in the atmosphere).

		Craters are named after Loránd Eötvös, János Bolyai and Miksa Hell the world famous astronomer of the XVIII century.
		However, craters are also named after Gyula Fényi, the researcher of sun eruptions, József Petzval, the outstanding expert of lenses and János András Segner, the Hungarian professor well known at German universities.
		Among the outstanding figures of our century, the Hungarian Tódor Kármán, the world-wide famous flying technician and honorary doctor at many German universities has also got a crater, as well as one of the most famous mathematicians and computer scientist, János Neumann.

		The most notable of these is 'Bolyai D' along the northeast rim and 'Bolyai W' to the northwest.
		The interior of the crater is relatively level, but rough in places due to impacts that have reshaped the surface.
		By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Bolyai crater.

		Most of the crater was long ago folded into the planet or eroded away.
		It exceeds even the Sudbury crater in Ontario, Canada, which is about 200 kilometers (125 miles) in diameter, he said.
		The town of Vredefort is situated at the centre of the crater, which is bigger than the Chicxulub depression made by an asteroid or comet at Yucatan, in Mexico.

		The first person to go beyond Euclid and to appreciate the significance of what he was doing was the German Karl Gauss, who was born in 1777 and had completed all of his great mathematical discoveries by 1799.
		According to calculations carried out in the 1920s, the protons inside the Sun do not move fast enough (they are not at a high enough temperature) to overcome their mutual electrical repulsion when they collide, and get close enough together for the strong force to take over.
		They do not have enough energy, that is, to climb in to the volcano from outside, and settle in the crater where the strong force dominates.

		ERB mentions that a crater of the moon is named for Copernicus.
		One of his famous postulations was corrected independently in the 19th century by Lobatchevsky and Bolyai and Riemann, giving the rise to the field of study known as non-Euclidian Geometry.

		Kolozsvár was no longer in Hungary after the Treaty of Trianon but rather it was in Romania and was renamed Cluj, so the Hungarian University there had to move within the new Hungarian borders and it moved to Szeged in 1920, where there had previously been no university.
		Of course the Institute was named after the famous Hungarian mathematician whose birthplace was Kolozsvár, the town from which the university had just been forced to move after the French awarded Transylvania and the Banat to the Rumanians.
		There is a crater on the moon honoring Imre Izsák.

		East of it is the tiny crater honoring Imre Izsák, the Hungarian-American expert of celestial mechanics of the Space Age (1929-1965).
		A tiny crater represents Gyula Fényi, the Jesuit solar astronomer (1845-1927), another one the Austro-Hungarian Nobel laureate, Richard Zsigmondy.
		But there is a Martian who proved that the craters on the Moon are not products of lunar volcanism but had been created by impacts of meteors from outside: Egon Orowan, while working on plasticity and fractures in solids, studied high resolution photographs brought back by the Apollo missions.
