In this episode we look at the emergence of Isaac Newton onto the public stage with the publication of his first work on Optics in the pages of the Philosophical Transactions of the Royal Society in 1672. We then examine the growing conflict between Newton and Robert Hooke and consider the work of the Society's secretary, Henry Oldenburg in fostering scientific communication during the turmoil.
In part 1 of our multipart biography of the father of physics, we look at the life of Isaac Newton from his early years in Woolsthorpe, Lincolnshire through his grammar school days to his time at Trinity College, Cambridge. We take some time to specifically look at the cultural and religious background that influenced his upbringing as well as his work on vision, color, light and optics.
In this episode we look at the work in mathematics and physics of Isaac Newton from his time at the University of Cambridge to the publication of the Philosophae Naturalis Principia Naturalis or "Mathematical Principles of Natural Philosophy". Specifically we look at the development of fluxional calculus, the Universal Law of Gravitation and Newton's Three Laws of Motion.
In this episode, we look at the work of four men who bridge the period between Galileo Galilei and Isaac Newton: Giovanni Battista Riccioli, Rene Descartes, Christiaan Huygens and Robert Hooke. In this discussion we pay particular attention to each man's work in physics that will set the stage for Newton's great synthesis.
We examine the events leading up to the heresy conviction of Galileo Galilei in 1633 including his dispute with Orazio Grassi regarding the comets of 1618, the publication of The Assayer, the deal with Pope Urban VIII and the publication of the Dialogue Concerning Two Chief World Systems.
In this episode we look at the 25 months leading up to the Congregation of the Inquisition censuring the two propositions related to the work of Copernicus; namely that the Earth moves and the Sun does not. We specifically examine the the statements regarding interpretation of Holy Scripture and Tradition by the Council of Trent and how those were expanded on by Cardinal Robert Bellarmine. We also consider Galileo's Letter to Castelli and Pauli Foscarini's Lettera as well as the role of Galileo's work and Letter to the Grand Duchess Christina in the proceedings and what follows.
In the first part of a three episode series on the emerging conflict involving Galileo Galilei, the Aristotelian natural philosophers of the Italian universities and the Catholic Church, we examine the factors that would lead to the initial confrontation of 1615 and 1616. These will include a debate that led to a fundamental revaluation of hydrology and a priority dispute on the discovery of sunspots. Finally, we discuss the piece of information that may have led to Galileo's open support of the Copernican model of the solar system.
In this supplemental episode, we look at the study of hydraulics related to pulling water up a pipe by Galileo Galilei. This leads us to the development of the mercury barometer by Torricelli and the investigations of atmospheric pressure and vacuums by Blaise Pascal and Florin Perier. This, in turns leads us to the work of von Geuricke and Robert Boyle.
In our third episode discussing the Scientific Revolution we look at the development of the linguistic device we call the fact from Latin legal ideas. We consider the work of Kepler and Galileo as well as the thinking of Blaise Pascal, Thomas Hobbes and Robert Boyle.
This week we look at the development of the idea of mathematics as a way to represent reality from perspective painting and accounting to Kepler's Harmonic Law. We also discuss the rise of the idea of laws of nature as the way in which the natural world was understood.
In the final part of the part of our biography of Johannes Kepler, we look at his scientific work from 1612 to his death in 1630 including the Epitome of Copernicus, Harmonice Mundi and the Rudolphine Tables. We consider the accusations of witchcraft against his mother, Katharina, and a number of other personal tragedies. In conclusion we discuss the Somnium, Kepler's work of science fiction.
In part three of our biography of Johannes Kepler we look at his years in Prague and the scientific work he did there including Astronomiae Pars Optica, Dioptrice and Astronomia Nova. We discuss how he arrived at his first two laws of planetary motion and his description of how lenses produce images in various optical systems including the eye. We also follow the personal tragedy of the death of his son Frederick, how wife Barbara and the chaos that eventually engulfed Prague.
Part 1 of our biography of of Johannes Kepler covering his early life from his seminary schooling to his time in Graz. We discuss his school in the lower seminary at Adelburg, the upper seminary at Maulbronn and at Sift at the University of Tubingen. After this we follow him to his assignment at the Protestant school in Graz and his work as the district mathematician. IN this we examine his attitudes on astrology and the publication of the Mysterium Cosmigraphicum.
This week we dock in Venice for a question and answer episode wherein I talk about podcasting, understanding quantum mechanics, the origin of the universe, and the evidence for human activity causing climate change. I also address questions about how doing the podcast has affected my teaching and where some of the strange things in academia come from. Then there's the story of the time I ran out of food but was saved by a do-it-yourself carwash in the middle of nowhere.
A discussion of the astronomical observation of Galileo Galilei and the escalating conflict with the Aristotelian Scholastics that dominated the Italian universities in the late 16th and early 17th centuries. Specifically, we discuss the 1604 nova and Galileo's telescopic observations of 1609 including those of the Moon, Jupiter and the phases of Venus.
