Salut mes amants des maths!
La derniere classe...je peux pas y croire ! (The last class...I can't believe it!)
For our last lecture, Dr. Daddel briefly asked about some of the material that was covered in the first few chapters that we covered. We then moved on to discuss some of the prominent figures of the middle of the 15th century as well as the 16th Century as follows:
PRINT: Middle of 15th Century
- 1494: 1st printed mathematics text
- Summa by Luca Pacidi (1445-1517)
- 1453: Eastern Roman Empire falls to Seljieck Turkes
- mass exodus of Byzantine intellectuals to Italian cities, slew of Greek manuscripts.
- Discovery of New World - 1490's
- increased willingness to explore, take risks, and challenge the authority of the church
- Next century: War between the Protestants and Catholics
15-16: Century Math
- Few Good Brave Men
- Polish astronomer Copernicus (1473-1543)
- challenged the geometric model of Ptolemy
- Danish astronomer Tycho Brahe (1546-1601)
- collected mountains of astronomical data
- Johan Kepler (1571-1630) Assistant of Brahe
- Formulated his three laws of planetary motions
- Galileo (1561-1642)
- study of motion, wrote dialogue on the two principal systems of the world, ridiculed the church supporting Geocentric theory.
- Rene Descartes (1596-1650)
- 1637: philosophical work with an appendeix deal with coordinate geometry (most important achievement of 17th centure)
- "I think therefore I am"
- 1663: The Pope placed his works on the Index of Prohibited Works
- Isaac Newton (1642-1727)
- Physics & Mathematics
- Differentiation
- F=ma
- Continued Kepler and Galileo's use of mathematics as language of Science , continued their work on planetary motion: F = gmM/d^2
- Establishing basic laws of physics, modified by the theory of relativity in 20th century.
- Gottfried Wihem Leibniz (1646-1716)
- German mathematician and philospher
- developed infintesimal calculus
- his math notation has been widely used since its publication
- 1st to describe the pinwheel calculator in 1685, invented the Leibniz wheel, used in arithmometer, 1st mass produced mechanical calculator
- refined binary number system
- noted for his optimism in philosophy
- 17th century: he was 1 of 3 greatest advocates of rationalism
- made major contributions to physics and technology and anticipated notions that surfaced much later in Biology, Medicine, Geology, Probability Theory, Psychology, Linguistics, and Information Science.
That's all for today, mes amis!
Bisous!
