  8. 1620 AD Paul Guldin (mathematicianborn 1577 ad, died 1643). 1620 ad –Guldi n formulates theorem about center of gravity.

  9. 1624 AD Henry Briggs (mathematicianborn 1561 ad, died 1630). 1624 ad –Briggspublished work „ ArithmeticaLogarithmica”that gives the logarithms of natural numbers from 1 to 20 000 and 90 000 to 100 00.

  10. It was the most important discovery of the seventeenth century, which had time at the beginning of this century. In future years were openedthe scientific academies and published printed works. Author of presentation Bartosz Zielinski The translation into English MarcinKowalczyk
