Scientific Revolution Flashcards
(33 cards)
how did evidence become more important in the sci-rev?
previously ideas were just accepted from textbooks and well respected figures, but now evidence and proof became far more important in new ideas
why did scientists design experiments?
- to establish new discoveries
- proof was essential in order for their idea to be accepted and respected
give an example of Isaac Newton doing an experiment?
- 1675 - royal society in London
- tested his theory of light, specifically of refraction
- used a glass prism
what became increasingly common over 17th C?
patronage of mathematicians and natural philosophers
how would patrons help scientists?
they would fund experiments/research
why were patrons needed?
17th C universities offered no support for those who were interested in new experimental nature
what did Galileo do?
- jan 1610 - used telescope to observe that Jupiter had 4 moons
- published findings in book called Siderius Nuncius
- named moons ‘Medicean starts’ after Duke of Tuscany, Cosimo de Medici
- sought out technological refinement of telescopes
what role did Universities play in sci-rev?
still remained central place of learning and research
what were universities particularly valuable for?
- study of medicine
- e.g. study of anatomy only really available at universities
- anatomy theatres built there
what were universities often the site for? why were these important?
- botanical gardens
- centralised site where people could discuss ideas
how did new world affect sci-rev?
discovery of new world expo did European world both intellectually and logistically
what problem did new world raise?
whether old framework represented by classical texts was still appropriate
what did the expansion of world stimulate?
- development of research
- research was intimately connected to the idea of discovery
what did Athanasius Kircher do?
- produced the first map depicting the world’s oceans currents
- made use of jesuit networks for his research
when were Coperncius findings published?
1543 - 1yr after his death
what were Copernicus findings?
- sun at centre of the universe
- earth + planets orbit it
what was Copernicus’s book called?
on the revolutionary of the Celestial spheres

- circulation of blood
- 1628
- ‘anatomical exercise on the motions of the heart and blood in animals’
what was Harvey’s argument?
- argued human heart serves to pump blood around entire body continuously
- arterial and venous system were 2 components of one larger circulatory system
- previously thought there were 2 separate circuits
how did Harvey prove his theory?
by experimenting on several animals and humans
what happened to Isaac Newton in 1703?
made president of royal society
how did newton contribute to maths ?
- contributed to several new theories and methods
- e.g. differential calculus
what physics breakthrough did Newton make?
- solved gravity puzzle
- 1687 ‘mathematical principles of natural philosophy’
- based on experimental observation
- 3 laws of motion
