EXCERPT: Quite surprisingly, everything that we know about the Universe can, in some way, be traced back to the most humble of all the entities we know of: an atom. An atom remains the smallest unit of matter we know of that still retains the unique characteristics and properties that apply to the macroscopic world, including what we observe as physical and chemical properties of matter. And yet, an atom is a fundamentally quantum entity inherently, with its own energy levels, allowable and forbidden transitions, and conservation laws. Moreover, even the humble atom couples to all four of the known fundamental forces, and also, importantly, possesses a non-zero mass. In a very real way, all of physics is on display, even inside a single atom. Here’s what the humble atom, all on its own, can tell us about the Universe... (MORE - details)
