Missions to Mars and Nuclear Fusion

“We are much closer today to being able to send humans to Mars than we were to being able to send men to the moon in 1961, and we were there eight years later. Given the will, we could have humans on Mars within a decade.” –Robert Zubrin Of all the planets in the Solar … Read moreMissions to Mars and Nuclear Fusion

The Cosmic Story of Carbon-14

“Life exists in the universe only because the carbon atom possesses certain exceptional properties.” –James Jeans Here on Earth, every living thing is based around four fundamental, elemental building blocks of life: hydrogen, oxygen, nitrogen and, perhaps most importantly, carbon. From diamonds to nanotubes to DNA, carbon is indispensable for constructing practically all of the most intricate … Read moreThe Cosmic Story of Carbon-14
