World Population Growth


200 years ago, the world had approximately 1,000,000,000 (1 billion) people. Today there are more than 7,000,000,000 (7 billion) people worldwide. By the end of the century, it has been predicted that Earth will have approximately 10,000,000,000 (10 billion) people. The majority, but not all, of the world’s population increase is due to impoverished third world countries as the governments of these nations are not meeting the same standards of industrialized countries in terms of educating their populous regarding sexual activity and birth control as well as affording free or subsidized birth control interventions. It is estimated that the world will not exceed 12,000,000,000 (12 billion) people as many countries, both industrialized and non-industrialized are now declining in their birth rates, due to conscious efforts made by governments to educate the general public in respect to sexual health

Fermat’s Last Theorem

Fermat's-Last-TheoremFermat’s last theorem was the last problem Pierre de Fermat ever claimed to have solved. Fermat often wrote in the margins of his books and one particular evening, while reading Arithmetica by the Greek mathematician Diophantus, he wrote “I have the answer to this equation, but the margin is too small to contain it”. Hours later that same night after writing this notation, Fermat died. Fermat was famous for writing in the margin of a books when he had figured out the correct answer for a problem, but for some reason he never provided the answer. Fermat was proven correct in each accounted notation by future mathematicians who came along posthumously. Fermat’s last claim however was unable to be solved and proven for centuries. Fermat’s last claim posited that the Pythagorean equation of a^2 + b^2 = c^2 does not have an infinite number of solutions when the squared exponent of all 3 numbers is any number greater than 1 or 2 (e.g. it is impossible to separate a biquadrant or cube into 2 biquadrants or 2 cubes, only squared numbers can be separated into 2). Andew Wiles of Princeton University eventually solved this equation in 1993 but could not publish his work until 1995 due to an error. Wiles resolved this problem 3 centuries after Fermat as no other mathematician was able to figure it out
