What is basically just an IQ score has roots in education, socioeconomic status, genetics, and environmental factors. Looking at any one of these roots doesn't give you a full picture of the tree, but it does tell you that a tree is there.

Imagine how many women could excel in science if not for the pernicious myth that science and math are a man's game. Likewise, fitness isn't defined by the Arnold Schwarzeneggers of the world.

A rainbow is the product of physics working for your appreciation of beauty.

How the original 'Cosmos' affected me personally was long-term. I wasn't born early enough to see the original series, but after getting a hold of it in my teen years, it was one of the driving forces behind my passion for science.

Evolution is ultimately why cancer is so deadly. Take two biopsies from different sides of a tumor, and they can be genetically very different, making it that much harder to fight. Variation is the toolbox of evolution, and this variation gives cancer strength.

Thor is magical, yes, but it is the magic of reality. His hammer was crafted 'in the heart of a dying star,' but so were you! Most of the atoms that make you up are in fact the innards of a ball of gas in space that got so heavy that it exploded. Stars died so that you could live, as physicist Lawrence Krauss would say.

The disturbing truth about science communication is that we have theories and ways of delivering messages that really are like putting a candle to the dark, as Carl Sagan would say. We aren't sure what will work, when, or how much. But for all that uncertainty, that doesn't mean we shouldn't try.

If a process or adaptation seems too smart for nature, that's a failure of your imagination, not the hand of God. I can make that claim because we have a working model of life's morphing and molding without it.
