The Discovery of the Speed of Light
While Aristotle believed that light could travel instantaneously, the first experimental attempt to measure the speed of light came from Galileo Galilei in 1667. He placed two people with covered lights on the top of hills that were about a mile apart. The first person was instructed to uncover his light, and when the second … Continue reading The Discovery of the Speed of Light → Continue reading

Astrolonomy?
A little over two weeks ago, we entered arguably one the thirteen coolest months of the zodiac: Aquarius. (Yes, we still love you Ophiuchus). But what does that really even mean? What is Aquarius? Well, as I am sure you can tell from the constellation, Aquarius is clearly a water-bearer. But it is also muchContinue reading “Astrolonomy?” Continue reading

“He’s Such an Ophiuchus”: The Forgotten 13th Zodiac Sign
In 2016, NASA shared this image of the zodiac constellations. Within this picture, we see the twelve signs commonly talked about in astrology, but we also see the presence of a less-discussed zodiac member: Ophiuchus. According to CNN, Ophiuchus is one of the 13 members of the Babylonian zodiac. However, 13 zodiac signs did notContinue reading ““He’s Such an Ophiuchus”: The Forgotten 13th Zodiac Sign” Continue reading

The Zodiac & Precession
Do you know your sun sign? Well, even if you do, it’s probably wrong! Let me provide some background. The zodiac is a term for the 12 constellations found along the Sun’s ecliptic (a circle that represents the Sun’s apparent path through the constellations throughout the year), while your sun sign indicates what constellation the… Continue reading

An Important Musician In Astronomy
Many will remember William Herschel as the one who found planet Uranus. This founding was shocking and revolutionary. After all, Uranus was the first star found by humans for a long time. Nevertheless, there are many more interesting things one can say about William Herschel. For one, he did not train to be an astronomer.Continue reading “An Important Musician In Astronomy” Continue reading

The Real Villain in Pluto’s Demise
The removal of Pluto as a planet was an emotional blow to anyone with a heart. It was a devastating betrayal leaving many asking questions that no one wanted to hear the answers to. While there were many reasons behind Pluto’s status change, the ultimate culprit is the dwarf planet Eris. Eris was discovered inContinue reading “The Real Villain in Pluto’s Demise” Continue reading

The Trouble With Astronomy 🤔
“Space,” it says, “is big. Really big. You just won’t believe how vastly, hugely, mindbogglingly big it is. I mean, you may think it’s a long way down the road to the chemist’s, but that’s just peanuts to space.” — Douglas Adams, The Hitchhiker’s Guide to the Galaxy So you want to study space? Now, … Continue reading The Trouble With Astronomy 🤔 Continue reading

Our Place in the Universe
How did you first picture the universe? Before being taught in school or at home what the universe was like, we often start to wonder about the world around us. This phase in a child’s life often leads to parents being questioned about almost everything. Questions range from why the sky is blue, why isContinue reading “Our Place in the Universe” Continue reading
The Resurgence of Flat Earth Theory
While believers in a Flat Earth have always existed (even after it became widely understood that the Earth is a sphere), the number of “Flat Earthers” has grown (and continues to grow) at alarming rates. So how is a fact that has been proven thousands of different ways over a few thousand years rejected byContinue reading “The Resurgence of Flat Earth Theory” Continue reading

Ultraviolet Catastrophe
While we discussed in class the importance of blackbody spectra continuous spectra, there is an important historical footnote in understanding where the famous blackbody curve arises from. Physics in the late 1800’s and early 1900’s predicted the wavelength-intensity relationship to be I α 1/λ^4, using a derivation based on classical statistical mechanics. This relationship closelyContinue reading “Ultraviolet Catastrophe” Continue reading
