# Writers’ Gallery

Our Writers' Gallery features short pieces about physics by authors who are both renowned physicists and prize-winning writers. Some of these are original contributions and others are excerpts from longer works. Many are linked to more information about the authors and their work.

#### Gödel's Proof Review

Gödel's Incompleteness Theorems shook the foundations of formal logic and mathematics, but its meaning remained elusive even to experts for years. Today, however, there's an easier way to see how Gödel discovered his theorems.

#### The Fifth Postulate

Many mathematicians since the time of Euclid attempted to solve a seemingly simple problem about parallel lines without success. Yet the success of their failures would reveal a whole new geometry and description of space and time.

#### ATOM: An Odyssey from the Big Bang to Life on Earth...and Beyond

It is difficult today to fully appreciate how recent is the notion that atoms are real physical entities, and not mere mathematical or philosophical constructs.

#### Cosmic Evolution

Simply defined, cosmic evolution is the study of change--the vast number of developmental and generative changes that have accumulated during all time and across all space, from big bang to humankind.

#### Chess and the Laws of Physics

Discovering the laws of physics is like trying to learn the laws of chess merely by observing chess games.

#### Beauty of Trajectory

"Ignoring air resistance, cannon balls move along parabolas," we learn in school, but the truth is more intriguing.
