Einstein’s Field Equations: A Long Road of Trial and Error

October 20, 2019

Einstein’s field equations would lead him down the path to perfecting his general theory of relativity. That path, though, was fraught with frustration as the numbers weren’t working out. Learn how even history’s most brilliant minds must persevere through setbacks. […]

Einstein’s Equivalence Principle: Expanding Our View on Gravity

October 20, 2019

The special theory of relativity, brilliant as it was, still had some holes to account for after its initial conception. Einstein’s equivalence principle would help to address these issues, though the equations would take years to refine. Discover how Einstein’s findings challenged conventional beliefs about the nature of gravity as well as geometry. […]

Einstein’s Grand Achievement: A General Theory of Relativity

July 18, 2019

In his quest to develop a general theory of relativity, Einstein spent many years working to resolve inconsistent and, at times, incorrect math. Another mathematician, David Hilbert, was also working toward solving the equations. So, the year of 1915 became a race to see who would be the first to complete the greatest and most celebrated theory in the history of physics. […]

Isaac Newton’s Influence on Modern Science

July 18, 2019

Aristotelian thought had dominated mathematics and astronomy for centuries, until revolutionaries like Nicolaus Copernicus and Galileo Galilei challenged those views. However, their theories still had holes, which Isaac Newton then filled. Newton’s contribution to scientific thought included his four basic laws: three laws of motion and the law of universal gravitation. […]

Aristotle on Astronomy: Supporters and Challengers

July 18, 2019

Centuries after Aristotle’s death, his theories on astronomy were met with some surprising endorsements from the Christian church, most notably Thomas Aquinas. Discover how both Plato and Aristotle’s theories were used to support theological doctrine. Later on the historical timeline, though, both Copernicus and Galileo challenged Aristotle’s views on planetary bodies. […]

How Plato and Aristotle Influenced Scientific Thought

July 18, 2019

Although Plato and Aristotle are still regarded as being among history’s greatest minds, their scientific theories may seem quaint by today’s standards. Nevertheless, a closer look at these theories reveals that they were actually quite logical. And, how does Aristotle’s account of the four earthly elements measure up according to today’s thinking?

Explaining Einstein’s Theory of Special Relativity

July 18, 2019

Einstein’s theory of special relativity clarified a lot of confusion circulating in the scientific community about the nature of light waves. This theory is still quite difficult to wrap your head around, though. We’ll use some mind-boggling, yet concrete, examples to illuminate this theory that forever changed our understanding of space and time. […]
