A Tidal Boat Dance 🌊

The above GIF shows the changing tides in a unique manner, by splicing together pictures taken throughout an entire day, at 20 minute intervals! The resulting effect is that it looks as if time is spiraling around the image. You can also see both pairs of high and low tides, one set during the day … Continue reading A Tidal Boat Dance 🌊 Continue reading

Spectroscopy and Space

Although Isaac Newton’s most famous contributions to astronomy are his laws of motion and gravitation, which he published in Principia, Newton also founded modern spectroscopy by publishing his second work, Opticks. Spectroscopy is an essential tool for astronomers because it allows them to not only analyze the presence of certain chemical elements, but also physicalContinue reading “Spectroscopy and Space” Continue reading

Is it possible for a star to be invisible?

One of the things I’ve always been most curious about on the topic of space is: is it possible for something that emits light (like a star) to emit light such as radio or gamma waves but not visible light? If such an object existed, it would be invisible to us, although it could stillContinue reading “Is it possible for a star to be invisible?” 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

Spring Tides and Neap Tides: How the Angle of the Sun and Moon Directly Impact How Earth is Stretched

The size and fluctuation of tides are directly related to geography and the physics of various places around Earth. The average size of tides, however, rises and falls each month in direct correlation to the angle of the Sun and Moon in relation to Earth. These extremes are called spring tides and neap tides, andContinue reading “Spring Tides and Neap Tides: How the Angle of the Sun and Moon Directly Impact How Earth is Stretched” Continue reading

The Origin of Tides: The Sun & The Moon

How much impact do The Sun and The Moon have on Earth’s tides? Also, what would happen to the Earth’s tides if there were no moon? These are questions that are covered in this blog post about tides. The Earth’s tides are results of the gravitational pull from the Sun and the Moon on Earth’sContinue reading “The Origin of Tides: The Sun & The Moon” Continue reading

Light and Vision

Humans can only see a limited range of all of the light that is in the universe. As learned in class, there is UV, radio, infrared, and Gamma ray waves. The light we can see is a small portion between the UV and infrared waves, but other animals rely on their ability to see light […] Continue reading

History of the Telescope

The telescope was first invented in the Netherlands in 1608. Its design quickly spread across Europe until it reached Galileo. Galileo spent years refining and redeveloping the telescope until it was much more powerful than before. He was able to observe many new astronomical phenomena such as the moons of Jupiter. For a while, GalileoContinue reading “History of the Telescope” Continue reading

What Causes Tides?

Have you ever been fishing? If you have, you probably know that your success partially depends on whether the ocean experiences a low tide or a high tide. But do you know the science behind what causes tides? Below is a quick and simple explanation why. Tides are caused by differential gravity. We know fromContinue reading “What Causes Tides?” Continue reading
