I am so old, I entered engineering school with a slide rule. And I left engineering school with a calculator. I can still use a slide rule but it's not a skill you especially need anymore.

Everyone, red state, blue state, everyone supports space exploration.

The philosophy of science is inherent in the process. This is to say, you think critically, you draw a conclusion based on evidence, but we all pursue discovery based on our observations. That's where science starts.

I often reflect on what an extraordinary time (pun intended) it is to be alive here in the beginning of the twenty-first century. It took life billions of years to get to this point. It took humans thousands of years to piece together a meaningful understanding of our cosmos, our planet and ourselves. Think how fortunate we are to know this much. But think also of all that's yet to be discovered. Here's hoping the deep answers to the deep questions-from the nature of consciousness to the origin of life-will be found in not too much more time.

Incidentally, the creationists that I've encountered diligently deny that our Earth's climate is being altered by people. This point of view and teaching is in absolutely no one's best interest. Here's hoping we can work together and preserve the Earth, for us - us humans.

The future of commerce is going to be all electronic. The gold standard was a fine idea, but electronic changes of funds and credits will be the future.

The thing about a theory in science is it allows you make predictions. Evolutionary theory allows us to predict what apples will taste good next harvest.
