Defining Quantum Mechanics
Quantum physics is recognized by many as one of the most difficult concepts in science. While this is surely true, it is not entirely beyond the grasp of the layman.

Contemporary ideology and its cost
While surfing the internet to understand such concepts as particle physics and the nature of consciousness, I encounter more rhetoric than thought. But in arguing over beliefs and theories, it's easier to blame one another for what's wrong with the world than to take responsibility.

Everything I Think I See -- Part 1: The Science of Observing
You've probably heard people say, "Life is what you make of it." Or how about, "Life is but a dream." In the years to come, science might just prove them right. In Part 1 of 3, find out what quantum theory has to say about this interesting topic and how we may, in fact, create our own reality. It's all science that frequently makes its way into our favorite SF stories.

A Life of Dedication - Maria Goeppert Mayer
Maria Goeppert-Mayer won the Nobel Prize for Physics in 1963, the second woman to do so. Her life and work speak of her dedication to and love of science at a time when women and wives found it difficult to take their place in the research community within universities. She was proud to be the seventh generation of university professors in her family.

Atheism in a Post-Religious World - Book Review
Tremblay labels religion a swindle and mental terrorism and explains, convincingly, why he chose these epithets. He demonstrates the inextricable link between the belief in the afterlife and immorality and castigates religion's intolerance coupled with its ever-shifting philosophical goalposts. Its dogmatism leads to a loss of experiential richness and to negative cognitive consequences to both the believer and his milieu.
