Know Your Scientist: Carl Sagan

If you have even the most remote interest in astronomy, it"s likely Carl Sagan"s name has came up an uncountable number of times in your research on the subject. Though he passed away 17 years ago, his words are splashed on letterheads, his quotes inked into the skin of science enthusiasts all over the globe and his influence can still be seen floating on the outskirts of our solar system, in two golden records that are destined to be the first man-made objects to break free from the sun"s influence, allowing the discs to roam freely in the spaces between stars for eternity, perhaps.

Continental Drift Theory: Understanding our Changing Earth

Plate Tectonics is the theory used to explain the structure of the Earth’s crust and many of the associated phenomena. The rigid lithosphere is split into 7 major ‘plates’ that slowly move on top of the underlying asthenosphere (mantle). This branch of geology studies the faulting and folding of the crust along the various boundaries; convergent, divergent, subduction, and conservative. The concept of Plate Tectonics was first coined by the German geophysicist Alfred Wegener back in 1915, but several ideas of continental drift date back many years before. Today we almost take for granted our knowledge of how the Earth’s crust shifts and regenerates on a continual cycle; but the theory of plate tectonics wasn’t widely accepted until the 1960s!

Know your Scientist: Michio Kaku

Michio Kaku is one of recent history’s greatest minds From Harvard to Super Strings, Kaku has an amazing story of how he came to change the world of physics and revolutionize scientific education. It seems that Kaku’s story has been a string of very well timed events, but no matter how lucky one might be, becoming such an influential figure in the science world takes hard work and perseverance.
