The Moon’s Locked On
Ever notice that we always see the same side of the moon? If all planets rotate, and all moons rotate, and even the sun rotates, why is it that our moon doesn’t seem to? In fact, it does, but it’s our fault we only see one side. The moon is in Tidal Lock with the … Continue reading
Nebulae – Clouds Alight in a Deep Ocean of Darkness
We took a brief look at nebulae, but some of you fed back to me that we didn’t take far enough of a look. A nebula, as explained a few days ago, is a big mass of gas and dust that either reflects or fluoresces light. They are a showcase for the stars that inhabit … Continue reading
Parallax
Fictitious scenario: My science project is due tomorrow! I’m supposed to talk about stars, and planets, and such! Better run to Wikipedia and grab some quick facts. (Note: I do not advocate the use of Wikipedia for academic research, but it’s sometimes a good place to start to familiarize yourself with a topic) According to … Continue reading
A Star is Born
We see them twinkle at night, we make odd shapes out of them, and one of them is a major component of our daily lives as members of a race and components of a complex ecosystem. But what is it, and how did it come to be? The Interstellar Medium When we look into space … Continue reading
Entropy: the Mathematical Description of Inevitable Disorder
Today, I shall talk about one of the most interesting aspects of thermodynamic law: the concept of entropy. Entropy is simply a measure of the energy in a system that is not available to perform useful work. It is the reason why machines are not considered completely efficient. For example, entropy in your body is all … Continue reading
All it Takes is One Mind
I posted this on Facebook a few days ago, but I really wanted it to be my first blog post. Einstein formulated the general theory of relativity in 1916. It made predictions that he didn’t live to witness proven: Gravitational deflection of light by a massive body (gravitational lensing) Perihelion shift of Mercury’s orbit The … Continue reading
