Literal Sun Jars Shrinking Stars for Energy Production – Professor Michael Brown, Swarthmore College
Science is the pursuit of knowledge – a search for an understanding. Sometimes that knowledge is simply collected and catalogued away for future reference (the laser was discovered in this manner) but, often, it is searched out vehemently to achieve something of...
Refining the Theories of Planet Formation – Dr Melissa A. Morris, State University of New York at Cortland
Science and philosophy are two of the most important pillars of human civilisation. But when it comes to the important questions, is there really much difference between them? Where do we come from? What is the meaning of life? Answers to such philosophical questions...
The Unexpected Spirals of Electron Density – Dr Jasper van Wezel, University of Amsterdam
