Newton and His Laws

Isaac Newton is a household name for his invention of calculus, laws of motion, and realization that gravity exists in the heavens (contrary to Aristotle’s beliefs!). College students that have studied introductory physics or math may have been exposed to Newton’s three laws of motion, but how exactly are they relevant in the context of … Continue reading Newton and His Laws Continue reading

Tidal Friction: a 5 hour long day to a month long day

Due to the Universal law of gravitation, we know that objects of equal mass have a larger gravitation force between them when they are closer together. Because the near side of the Earth is closer to the Moon than the far side of the Earth, the force between the Moon and the near side ofContinue reading “Tidal Friction: a 5 hour long day to a month long day” Continue reading

Stonehenge and Archeoastronomy

Stonehenge is one of the most easily recognizable sites across the globe. Often designated as one of the wonders of the ancient world, Stonehenge has both fascinated and confounded humanity for centuries. While some may still argue about how Stonehenge came to exist, whether it be aliens, magic, or old-fashioned hard work and sweat, oneContinue reading “Stonehenge and Archeoastronomy” Continue reading

The Hubble Space Telescope

The Hubble Space Telescope is one of humanity’s greatest achievements. Deployed in 1990, the telescope is responsible for many of the discoveries made about distant solar systems and galaxies. According to the Nasa website, the Hubble “has made more than 1.4 million observations.” Without this great invention, we would still in be in the darkContinue reading “The Hubble Space Telescope” Continue reading

Examining Historical Astronomy Through the Lens of Fiction

Humans have been studying the skies for millennia with our theories about how space works evolving and growing over the same amount of time. Today, our understanding of astronomy is based primarily on natural and mathematical laws that allow us to evaluate and understand the heavens objectively. However, humanity’s understanding of astronomy has not always … Continue reading Examining Historical Astronomy Through the Lens of Fiction Continue reading

Gravity of a Mysterious Object

Credit: Caltech/R.Hurt (IPAC) We know that there are 8 planets in the Solar System. This is a fact. You would be crazy to think that there is a 9th planet out there orbiting beyond Pluto. After all, if there was a 9th planet, why haven’t we seen it yet? Well, meet Konstantin Batygin, a professorContinue reading “Gravity of a Mysterious Object” Continue reading

Eppur Si Muove

… were the words (supposedly) quietly uttered by Galileo following his trial with the Catholic church. The Church disapproved of his support of the Copernican system which depicted the Sun being at the center of our solar system with Earth orbiting it. This contrasted with the Church’s view that we were at the center ofContinue reading “Eppur Si Muove” Continue reading

waves and particles and dualities oh my

What is light? It’s a simple question, really. And simple questions have simple answers, right? Sometimes they do, yes. But, tragically, this time it doesn’t. Most people know light acts light a wave. It refracts (thanks Pink Floyd), reflects, and diffracts just light waves are supposed to. Similarly, the electromagnetic spectrum illustrates the wave-like propertiesContinue reading “waves and particles and dualities oh my” Continue reading

Tides and the Planets

Primarily, the tides on Earth are controlled by the Moon. The gravitational pull of the Moon causes the tides to fluctuate between high and low. Though small, even the Sun has a tiny impact on the tides. Whenever both the Moon and the Sun align, the tidal range, However, what about the other celestial bodiesContinue reading “Tides and the Planets” Continue reading
