  The Theoretical: Do gravitons exist, or should they? By: Ian Davis -------------------------------------------------------------------------------------------------------------------------------- Credit and found:  https://www.google.com/url?sa=i&url=https%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3DiQpZQLLbk6E&psig=AOvVaw3XvFRLLa8caB3aqfeRkTKT&ust=1622293201486000&source=images&cd=vfe&ved=0CAIQjRxqFwoTCOCfnqO37PACFQAAAAAdAAAAABAD Introduction: You may or may not have heard of the expression "Gravitons" in a physics class, or perhaps any college-level science class that is introducing the Theoretical. I heard the term when I was watching a video by DoS on YouTube talking about the map of particle physics, and the video had introduced the term. There, I have begun to research them a little, and it turned into a rabbit hole. We know there are a large amount of "force carriers" that we have. Like we have covered before,  the strong force is a Gluon,...

The Wonders of Energy: Why isn't "cold" a thing? How do other compounds, mixtures, and materials make something 'colder' like glycol?

The Wonders of Energy: Why isn't "cold" a thing? How do other compounds, mixtures, and materials make something 'colder' like glycol? By: Ian Davis -------------------------------------------------------------------------------------------------------------------------------- Introduction: I'm sad to ruin your childhood, but 'cold' is just a term, and not really a thing in and of itself. I used to thing that 'cold' was just tiny particles shaped like little snowflakes that would make something cooler, however, as soon as I got into middle school, I learned that 'cold' is just the absence of heat. Now I love knowing the "ins-and-outs" of this little definition (including thermal equilibrium don't worry) but nevertheless always had questions about one particular thing, how do certain compounds, mixtures, and materials make something 'colder' and why is that their natural property? We are used to understanding that if...
