A man and his wife were making their first doctor visit prior to the birth of their first child. After everything checked out, the doctor took a small stamp and stamped the wife's stomach with indelible ink.
The couple was curious about what the stamp was for, so when they got home, he dug out his magnifying glass to try to see what it was. In very tiny letters, the stamp said, "When you can read this, come back and see me."
Johan van Waveren HuddeBorn 23 Apr 1628; died 15 Apr 1704 at age 75.Dutch mathematician and statesman who, after an education in law, became interested in mathematics, though for a limited time (1654-63). He worked on improving the algebraic methods of René Descartes, seeking to extend them to the solution of equations of a higher degree by applying an algorithm. He also developed an algorithm based on Fermat's method to deal with the maxima, minima and tangents to curves of algebraic functions. Later, he served as burgomaster of Amsterdam for 30 years. During this time time he made a mathematical study of annuities. Hudde continued with an interest in physics and astronomy, producing lenses and microscopes. He collaborated with Baruch Spinoza, of Amsterdam, on telescopes. Hudde determine that in a telescope, a plano-convex lenses were better than concavo-convex .« |
