Turbulent Times

A plane hit a patch of severe turbulence and the passengers were holding on tight as it rocked and reeled through the night. A little old lady turned to a minister who was sitting behind her and said, "You're a man of God. Can't you do something about this?"

John Landen

Died 15 Jan 1790 at age 70 (born 23 Jan 1719).British mathematician who made important contributions on elliptic integrals. As a trained surveyor and land agent (1762-88), Landen's interest in mathematics was for leisure. He sent his results on making the differential calculus into a purely algebraic theory to the Royal Society, and also wrote on dynamics, and summation of series. Landen devised an important transformation, known by his name, giving a relation between elliptic functions which expresses a hyperbolic arc in terms of two elliptic ones. He also solved the problem of the spinning top and explained Newton's error in calculating the precession. Landen was elected a Fellow of the Royal Society in 1766. He corrected Stewart's result on the Sun-Earth distance (1771).
