If you're an adult and you choose not to believe in science, fine, but please don't prevent your children from learning about it and letting them draw their own conclusions.

I like to regard myself as someone who's capable of critical thought, that is to say, who can evaluate claims.

NASA is an engine of innovation and inspiration as well as the world's premier space exploration agency, and we are well served by politicians working to keep it that way, instead of turning it into a mere jobs program, or worse, cutting its budget.

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

Of all the failed technologies that litter the onward march of science - steam carriages, zeppelins, armoured trains - none has been so catastrophic to prosperity as the last century's attempt to generate electricity from nuclear fission.

As with sound, images are subjective. You and I may not see the same color red as red, but we will probably agree that the image on the screen is a digital image or film image, based on contrast, bit depth, and refresh rate.

Giving users easy access to many different kinds of digital assets on the blockchain and, particularly, tokens that are linked to assets in the real world, is crucial to seeing blockchain adoption reach the next level, and I applaud Digix Global's initiative in being the first of many such projects to successfully launch.

We need to manage holistically, embracing all of our science and traditional knowledge - all sources of knowledge. We can do that from the household to government to international relations.
