From Gary Felder's website: **Science for the General Public**

One of my hobbies is writing papers on scientific topics. These papers should be accessible to people with no math or science background, although I like to think they might also be interesting to some people in those fields. All of these papers are hosted on the Math and Physics Help Home Page maintained by my brother, who has many more papers of his own there. Alternatively, you can jump directly to any of my papers from here:

The Expanding Universe

This paper is an introduction the the big bang model of the universe, including what it means to say the universe is expanding and what we mean by "The Big Bang."

Beyond the Big Bang: Inflation and the Very Early Universe

This paper discusses some of the problems with the standard big bang model and how cosmologists have solved these problems with a theory known as "inflation." As the paper explains, inflation doesn't replace the big bang model but rather supplements it.

Quantum Mechanics: The Young Double-Slit Experiment

My brother Kenny Felder and I co-authored this paper, which introduces the basic concepts of quantum mechanics. We use for illustration the famous double-slit experiment, which shows how matter acts both like particles and like waves.

Quantum Mechanics: What Do You Do with a Wavefunction?

Another collaboration with my brother, this paper is the only one in the bunch that requires a physics background. This paper is designed for people who are taking or have taken a course in quantum mechanics and want some help pulling all the ideas and the math together to see the big picture.

Spooky Action at a Distance: An Explanation of Bell's Theorem

This paper outlines Bell's proof that the experimental results of quantum mechanics can only occur if particles can instantly affect each other at large distances. As with all these papers, no math or science background is necessary.

Things Fall Apart: An Introduction to Entropy

Everyone from physics students to readers of popular science literature has heard that entropy is a measure of disorder and that it always increases in the universe. In this paper I explain what entropy is and why it always increases. Put another way, this paper explains why some processes in nature are irreversible.

Bumps and Wiggles: An Introduction to General Relativity

As the title suggests, this paper introduces some of the basic ideas of Einstein's General Theory of Relativity: curved spacetimes, black holes and more. This one might be best read after my brother's paper on special relativity.
