	Carl Friedrich Gauss Biography
		Gauss earned a scholarship and in college, he independently rediscovered several important theorems; his breakthrough occurred in 1796 when he was able to show that any regular polygon, each of whose odd factors are distinct Fermat primes, can be constructed by ruler and compass alone, thereby adding to work started by classical Greek mathematicians.
		Gauss was the first to prove the fundamental theorem of algebra; in fact, he produced four entirely different proofs for this theorem over his lifetime, clarifying the concept of complex number considerably along the way.
		Gauss' personal life was overshadowed by the early death of his beloved first wife, Johanna Osthoff, in 1809, soon followed by the death of one child, Louis.

	Carl Friedrich Gauss Summary
		Gauss envisaged the possibility of developing a geometry without the parallel postulate and on one occasion even measured the angles of a triangle formed by three mountains, finding the sum to be two right angles within the limits of experimental error.
		Gauss was a child prodigy, of whom there are many anecdotes pertaining to his astounding precocity while a mere toddler, and made his first ground-breaking mathematical discoveries while still a teenager.
		Gauss predicted correctly the position at which it could be found again, and it was rediscovered by Franz Xaver von Zach on December 31, 1801 in Gotha, and one day later by Heinrich Olbers in Bremen.

	Andrey Markov Summary
		Markov involved himself in anti-Czarist, liberal politics and protested Czar Nicholas II (1868-1918) refusal to elect writer Maxim Gorky (1868-1936) to the St. Petersburg Academy in 1902.
		Markov received his bachelor's degree in 1878 for a thesis on differential equations and continuing fractions, for which he was also awarded a gold medal.
		Markov apparently saw few practical applications for his theorem, mostly because of the state of science at that time, when it was believed that natural laws determined most events.

		I will present a generalization of this result due to Vadim Kaimanovich which is formulated and proved in the language of Markov operators.
		In this talk, I will present the most basic results of the theory: the area theorem, Koebe's one-quarter theorem and the growth and distortion theorems.
		We shall see that the Bieberbach conjecture arises naturally as a consequence of these elementary results and that many interesting techniques were developed in order to prove partial results in the direction of the conjecture.

	Human Intelligence: Karl Friedrich Gauss
		Gauss was a mathematically precocious child, and in later years he would joke that he could do computations in his head before he could talk.
		Intelligence theorists are indebted to Carl Gauss in particular for his discovery of the method of least squares, a mathematical concept that is used in statistical analyses like regression.

		The estimates of headwind and crosswind are extracted from the radial wind components using the Gauss-Markov Theorem, as are the estimates of the error variances.
		The wind field variability estimates are computed by comparing the radar measured radial velocities to the corresponding radial component of the estimated mean wind.
		This extent is then the vertical window used for the given analysis level, and the slope of the associated line is the shear.

		Andrey Andreevich Markov was born in Ryazan as the son of the secretary of the public forest management of Ryazan, Andrey Grigorevich Markov, and his first wife, Nadezhda Petrovna Markova.
		Markov initially refused from accepting this decree and wrote an explanation where he expressed his decline from being an “agent of the governance”.
		Markov was rejected from a further teaching activity at the Saint Petersburg University, and he eventually decided to retire from the university.

		I believe it was Poincare who stated that "everyone" was assuming normality; the theorists because the empiricists had found it to be true, and the empiricists because the theorists had demonstrated that it must be the case.
		This is a special case of the Central Limit Theorem, which states that, under certain conditions, the sum of a large number of random variables is APPROXIMATELY normal.
		Gauss came up with many characterizations of normality, and did use it to improve fits to orbits of objects within the solar system.

	Gauss–Markov theorem - Wikipedia, the free encyclopedia
		In statistics, the Gauss–Markov theorem, named after Carl Friedrich Gauss and Andrey Markov, states that in a linear model in which the errors have expectation zero and are uncorrelated and have equal variances, the best linear unbiased estimators of the coefficients are the least-squares estimators.
		In terms of the matrix algebra formulation, the Gauss–Markov theorem shows that the difference between the parameter covariance matrix of an arbitrary linear unbiased estimator and OLS is positive semi definite (see also proof in external link).

		The earliest form of linear regression was the method of least squares, which was published by Legendre in 1805, and by Gauss in 1809.
		Legendre and Gauss both applied the method to the problem of determining, from astronomical observations, the orbits of bodies about the sun.
		Gauss published a further development of the theory of least squares in 1821, including a version of the Gauss-Markov theorem.

		Within the context of an emphasis on applications to the kinds of data encountered by social scientists, this course takes a second, and moderately rigorous, look at the general linear model (which subsumes regression, analysis of variance, and covariance analysis).
		The matrix form of the generallinear model is developed; properties of the ordinary least squares, generalized least squares, and maximum likelihood estimators for this model are discussed; the Gauss-Markov theorem is stated, proven and generalized; various problems and complications encountered in empirical applications are analyzed; model diagnostics, residual and influence analysis techniques are developed.
		This model and its estimators then are generalized to simultaneous equation systems with and without unobserved variables; principles of path analysis are developed; and applications to social science data are discussed.

		The Gauss-Markov Theorem, however, requires that for all Yi, Xi, the following conditions are met: The conditional expectation of Y is an unchanging linear function of known independent variables.
		First, the Gauss-Markov Theorem assumes that the expected value of the disturbance term is zero.
