Albert Einstein vs Galileo Galilei

Einstein published his paper 'On the Electrodynamics of Moving Bodies', introducing the special theory of relativity. He proposed that the laws of physics are the same for all non-accelerating observers and that the speed of light is constant, revolutionizing physics.

In a follow-up paper, Einstein derived the equation E=mc

Einstein completed his general theory of relativity, describing gravity as the curvature of spacetime caused by mass and energy. The theory predicted phenomena like gravitational lensing and black holes, and was confirmed by Eddington's 1919 solar eclipse observations.

Einstein was awarded the Nobel Prize in Physics for his explanation of the photoelectric effect, not for relativity. His work demonstrated that light consists of discrete quanta (photons), which was a key contribution to quantum theory.

Einstein, a Jewish pacifist, fled Nazi Germany after Hitler's rise to power. He renounced his German citizenship and accepted a position at the Institute for Advanced Study in Princeton, New Jersey, where he remained for the rest of his life.

Einstein signed a letter to President Franklin D. Roosevelt, warning that Nazi Germany might develop atomic weapons and urging the U.S. to begin its own nuclear research. This letter led to the Manhattan Project, though Einstein later regretted his role.

Galileo improved the Dutch telescope, achieving 20x magnification. He used it to observe the Moon's craters, Jupiter's moons, and the phases of Venus. These observations provided evidence for the Copernican heliocentric model and challenged Aristotelian cosmology.

Galileo discovered four moons orbiting Jupiter (Io, Europa, Ganymede, Callisto). This observation demonstrated that not all celestial bodies orbit Earth, contradicting geocentric models. He published the findings in Sidereus Nuncius.

The Catholic Church declared heliocentrism heretical and ordered Galileo to abandon his support for Copernican theory. He was warned not to teach or defend heliocentrism. This marked the beginning of his conflict with Church authorities.

Galileo published a dialogue comparing Ptolemaic and Copernican systems, arguing for heliocentrism. The book was seen as violating the 1616 injunction. It led to his trial and condemnation by the Inquisition.

The Roman Inquisition tried Galileo for heresy, forcing him to recant his heliocentric views. He was sentenced to house arrest for life, where he continued scientific work. This event symbolized the conflict between science and religious authority.
