I'm a scientist by training. Without scientists, you'd not have the monitor you're reading this post on. Nor a cell phone, because the science of the technology would not exist, and that includes quantum mechanics. Yup, the science of silicon and doping chemistry has changed our world dramatically. Science does indeed investigate, using the scientific method, and create new realities (GPS satellites) as well as helping us to understand old ones, such as understanding eclipses which used to startle early man.

I understand his point, we need to maintain skepticism, but science leads us into new directions. There are many doctors who are charlatans too. The scientist proposes new ideas to be investigated and proven right or wrong. Also, science does propose and discuss theories. But that's the point, they are theories until proven right or wrong.

Happily, at least, we have something plausible to work with. And, BTW, good or evil, scientists brought and end to WWII.
