His theory states that the earth and the planets move around the sun and it became the foundation for modern astronomy
(1546-1603) Astronomy made further progress with him, a Dane, who constructed an observatory on the island of Hven. He spent 25 years there and was forced to leave. His life work was made up of facts that were built up based on his investigations and observations.
(1540-1603) He was a jurisconsult who created an algebraic language. Until then, numerals were always used in operations and the unknown and its quantities were shown as abbreviations and signs.

(1493-1541) He studied medicine and rejected the Greek and Arab authors to devote himself to the direct observation and natural remedies.
(1514-1564) He used Paracelsus' ideas as the basis for a study of the human body and anatomy. He was the physician of Charles V and Philip II and from him healing science developed.
