Archaeoastronomy
Stonehenge The concept of time is something that is invaluable to humans. The passage of time brings with it changes in weather, seasons, rainfall, and daylight. Especially during the beginning of civilizations, it was important to understand how much time passed to keep track of the changing conditions. In order to keep track of the … Continue reading Archaeoastronomy → Continue reading

Derivation of Kepler’s Second Law
Here is a detailed derivation of Kepler’s second law of planetary motion. I find this derivation of Kepler’s Second Law and similar derivations I have seen for other laws extremely interesting. This is actually the most straightforward of the derivations of Kepler’s three laws. The reason I am so intrigued by this derivation is because … Continue reading Derivation of Kepler’s Second Law → Continue reading
Contextualizing Historical Astronomers
Sir Isaac Newton- Born: 12/25/1642, Died: 3/20/1726 Isaac Newton is regarded by many as the father of modern science. Not only did he come up with his three laws of physics, but he also invented calculus as he was trying to understand the orbital paths of comets he was observing. The application … Continue reading Contextualizing Historical Astronomers → Continue reading

Moon and Tides – The Magic of Gravity
Our sea has a periodic rising and falling phenomena. At a time, the sea will go up and reach to the peak, and at another time, the sea will go down and leaves us an island or a beach. This phenomena is called tides. The tides are mainly caused by gravitational force from Moon. When … Continue reading Moon and Tides – The Magic of Gravity → Continue reading
Privatization in Aerospace
In the past week, the Trump administration published a document, obtained by the Washington Post, that described its plans to cease funding for the International Space Station and leave the station up for grabs for the private sector. This is being done to free up the NASA budget for other Aerospace Endeavors. NASA currently spends … Continue reading Privatization in Aerospace Continue reading
Absolute Hot
We all have heard about absolute zero – the coldest temperature possible. At this point, atoms cease to move completely. All heat is really is just the movement of atoms and the energy with which they’re moving. Hotter things tend to have more energy, and their atoms move more. Thermodynamically, it is impossible to reach … Continue reading Absolute Hot → Continue reading

Picture: Artist depiction of gravitational waves at work Gravity has long been one of the most transfixing ideas in our universe. For centuries, we have tried to crack the code of what exactly lies beneath our 9.8 meters per second squared. Since the apple first dropped on Newton’s head, we’ve been pining to understand … Continue reading gravity.wav → Continue reading
A Powerful Letter
Chapter 3 explained to us how Galileo solidified the Copernican revolution, and sealed the case on how Earth would be viewed in perspective of the universe. In 1615, Galileo wrote a letter to Grand Duchess Christina, in attempt to accommodate his observations’ confirmation of Copernicanism with the doctrines and scripture of the Church. He held … Continue reading A Powerful Letter → Continue reading
