Uranium is used to fuel the world's nuclear power plants, but a vocal segment of the scientific community claims that it's too dangerous and rare a chemical to sustain that role for much longer.
In the feature-length documentary , they make the case for a much more efficient and sustainable answer to our energy needs.
He is Module Leader for three modules, including a specialised third- and fourth-year module in ore minerals.
He is Year Tutor for first- and second-year Earth Science students, which involves providing academic assistance and arranging Welcome Week for newly arriving ...
Carbon is naturally in all living organisms and is replenished in the tissues by eating other organisms or by breathing air that contains carbon.
At any particular time all living organisms have approximately the same ratio of carbon 12 to carbon 14 in their tissues.
They're the hidden ingredients of everything in our world, from the carbon in our bodies to the metals in our smartphones. The good news is that we haven't finished; there may be still gold hiding in the mix. And, today, it's one of the most widely bought and sold metals in the world. Copper is in wire, electronics and computer chips, plumbing and other building materials. These guys can trade their copper futures; I've got to unload my copper today. In pure metals, the atoms are arranged in orderly rows and columns. Here, at the Cortez Mine, in Nevada, high-tech prospectors are moving mountains, closing in from above and below. Which raises a question: if the gold is invisible to the naked eye, how do they even know if they're digging in the right place? Eight bars, million, sitting on this unassuming little table. Of all the elements that touch our lives, nothing drives humankind to acts of love or destruction like gold. Copper alone is impressive stuff, but when ancient metallurgists combined it with another element, they invented a much tougher material that went on to conquer the world. Tin; symbol Sn; atomic number 50—50 protons and 50 electrons. If you're like me, you care about the elements and how they go together,… The problem is it's exceedingly rare stuff in the earth's crust, and it's getting harder to find all the time. Mike tells me that each bar represents about a million pounds of rock that had to be moved and processed.His research involves interpreting laboratory and field measurements using numerical modelling, and improving the accuracy of chemistry within atmospheric models.Paul lectures in a variety of areas of Earth Sciences, specialising in ores and igneous/metamorphic processes.
