Gravitational Mysteries
by me The idea of gravity, the fundamental force that controls how objects move in the universe, is both intriguing and mysterious. Gravity is a force that pulls objects toward each other; it controls everything from an apple falling from a tree to a planet’s orbit around a star. It’s a force that operates over […] Continue reading
Blog 2— Historical Context: the Ptolemaic Model
The Ptolemaic Model stood as the most accurate way to predict the movement of planets for 1,500 years, even though it was a geocentric model. This obviously serious error in the model caused there to be small inaccuracies in the predictive abilities of the model, but it was the best incorrect model created, so it […] Continue reading

The New Wave
In a groundbreaking discovery, scientists have found evidence of ripples in the fabric of the universe, caused by the movement of colossal black holes. Albert Einstein once hypothesized this phenomenon – gravitational waves. Essentially, these are cosmic tremors that stretch and squeeze space itself. Imagine throwing a stone into a pond and watching the ripples […] Continue reading
Tides
Most people (including my past self) think that tides are only caused by the moon. While the moon does have a big impact on the tides. The sun also plays a big role in the way the tides move. The moon and the sun both have gravitational forces that pull on the Earth and cause […] Continue reading
Kepler’s Laws of Planetary Motion
After meticulously calculating the data that Tycho Brahe collected, Kepler discovered three different laws that described how planets move. Kepler’s First Law – The planets orbit in ellipses, not circles nor epicycles. For majority of history, it was thought that planets orbit through epicycles because the orbit of the planets must be perfect. However, the […] Continue reading

The Banner of Heaven
This term, originally coined in the late nineteenth century, at least with its current connotation, began to speak to me in a unique way in high school. I took a backpacking trip in Northern California, and experienced a dry, warm, cloudless night with no shelter but a mosquito net. The sky was brilliant, and it felt like […] Continue reading

Understanding Gravity
There are many different ways to visualize how gravity functions. However, one of the best way I have found to visualize gravity is with strings and using the center of mass. Gravity is the weakest force of the four fundamental forces, however, it works over an infinite amount of distance. I put this in perspective […] Continue reading
Blog 2: Ancient Mayan Astronomy
Thousands of years before telescopes and computers, the ancient Mayans had the ability to predict eclipses and track retrograde motion. They are some of the most advanced astronomers of the ancient world. Astronomy was a central part of Mayan culture. Calendars were based on the movements of the Sun, moon, and planets and festivals, rituals, and […] Continue reading

Gravity
What is Gravity? Gravity is the physical attraction of masses. The idea that all masses attract each other. Why Does Gravity Happen? Gravity happens due to curvature in spacetime, it bends and warps space and that space causes an attraction between the objects.

Spring Tides and Rising Sea Levels
The effects of human-induced climate change are becoming more and more apparent over time. Some of the most highly impacted areas are those on the water, who, when facing spring tides, can experience dangerous levels of flooding. Spring tides occur when the Sun and the Moon are exerting gravitational force on the same line, both […] Continue reading
