Climate change is a real deal. So, hey deniers - cut it out, and let's get to work.

Winter lingered so long in the lap of Spring that it occasioned a great deal of talk.

Unlike science, creationism cannot predict anything, and it cannot provide satisfactory answers about the past.

I say to the grownups, if you want to deny evolution and live in your world, that's completely inconsistent with the world we observe, that's fine. But don't make your kids do it. Because we need them. We need scientifically literate voters and taxpayers for the future. We need engineers that can build stuff and solve problems.

I've always loved airplanes and flight. The space program was really important to me as a kid. I still have a photo of Armstrong and Aldrin on the moon in my living room.

As you may know, I am a mechanical engineer.

Climate change is happening, humans are causing it, and I think this is perhaps the most serious environmental issue facing us.
