Asteroid Collision! Suppose that an asteroid traveling straight toward the center of the earth were to collide with our planet at the equator and bury itself just below the surface. What would have to be the mass of this asteroid, in terms of the earths mass M, for the day to become 25.0% longer than it presently is as a result of the collision? Assume that the asteroid is very small compared to the earth and that the earth is uniform throughout
Descartes’ Metaphysics and Epistemology ● Rene Descartes belongs to a group called continental rationalists: 3 prominent rationalists at the time: him, Baruch Spinoza, and Gottfried Leibniz. ● Descartes was caught in the astronomical debate about what is at the center of the solar system (Earth or the sun). ○ The geocentric model became harder to support because observation showed evidence against it, such as retrograde movement of the planets. ○ The heliocentric model became more popular because it was more simple than the geocentric model; it already accounted for epicycles, retrograde, and circular movement without having to explain it. This is what made the geocentric model more complex. ● Metaphysic
