The Cuban “Wet Foot Dry Foot” Policy

Cuban-migrant

The Cuban “Wet Foot Dry Foot policy” describes the fact that since 1995, any Cuban who reaches the United States of America will be accepted by the U.S. and therefore able to live and work in the U.S. as a landed immigrant with paperwork to bolster their legitimacy when finding work, applying for loans, and paying income tax. The goal of bringing one’s family to join them in the future is why many Cubans have taken on this monumental challenge of traveling from Cuba to the U.S. by boat, often overcrowded and handmade which has lead to many deaths by drowning. If caught by the Cuban authorities for trying to flee Cuba, migrants are repatriated and given a fine or jail time in Cuba. Barack Obama ended the Wet Foot Dry Foot policy as his last act in office as President of the United States of America in the hopes of improving diplomatic relations between the U.S. and Cuba

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 a2 + b2 = c2 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
