(Image credit: Johannes Kepler/PD-US) How did astronomers discover that there is such a thing as the perihelion and aphelion? Did they realize the sun was bigger or smaller during certain periods of the year? The answer is no. Edward Bloomer, an astronomer at the Royal Observatory in ...
For starters, his magnum opus –Philosophiæ Naturalis Principia Mathematica(“Mathematical Principles of Natural Philosophy”), which was first published in 1687 – laid the foundations for classical mechanics. In it, he formulated his Three Laws of Motion, which were derived from Johann Kepler’...
What did Galileo do to experiment with gravity? Galileo: Galileo was an Italian scientist, mathematician, and astronomer who revolutionized the way we understand the world. Galileo developed a working telescope that allowed him to observe the moons of Jupiter and the phases of Venus that became ce...
Kepler! This great landmark crater named for Johannes Kepler only spans 32 kilometers, but drops to a deep 2750 meters below the surface. It’s a class I crater that’s a geological hotspot! As the very first lunar crater to be mapped by the U.S. Geological Survey, the area around ...
Sometimes whole substructures of mind may break or crumble due to the pressure from other substructures that have more weight. Are we able to question ideas deeply ingrained in our minds at an early age? Why did it take 2000 years to discover some obvious errors of Aristotelian physics and ...
. Newton’sPrincipia,which will go down as one of the most groundbreaking works in the history of mankind, was published at Halley’s expense. However, critics incredulous about the mysterious pull of gravity questioned Newton aboutwhyhis proofs worked; why did gravity work the way it did?
The variable G, called "big G," is the universal gravitational constant. It has the same value everywhere in the universe. Newton didn't discover the value of G (Henry Cavendish found it experimentally after Newton's death), but he found the proportionality of force to mass...
Although Kepler 37-b has held the title of "smallest planet" for over a decade, it won't hold that designation forever, Barclay said. Since the Kepler space telescope was retired in 2018, scientists have been devising new ways to discover exoplanets, including the Nancy Grace Roman Space Te...
