Dr. David Cornelison

Dr. David Cornelison has been working as an educator and scientist in Arizona and Missouri universities for the last 25 years.  Since 2010, he has been the head of the Department of Physics, Astronomy and Materials Science at Missouri State University.  His research interests lie at the intersection of experimental condensed-matter physics and astrophysics, while his educational efforts have focused on outreach to the K-12 school system.   Most of all, he believes in curiosity-driven learning in the sciences and all other fields.

Hack 4 Good

When we think of hacking, we usually take a negative view.  The image brought to mind is that of scurrilous, disaffected individuals intent on causing harm in the computers of the world, while enriching themselves as much as possible.  An organization, “Hack 4 Good SGF” wants to change that impression.  They see hacking as a way to build solutions to problems that exist in our everyday, computer-dominated world. 

If you have paid attention to the recent predictions of technocrats, you know that a future filled with robots is almost certainly coming.  The only real question is not if they will become ubiquitous (yes, they will), or even when (pretty soon) but what our response will be.  Will the onset of widespread automation displace workers to a problematic extent or will, as in days past, changes in technology result in new and better jobs for those who are willing to retool for the future?  To give us some insight into the potential pitfalls and solutions, we talk with Dr.


While it is true that the path of totality for the latest solar eclipse passed directly over Missouri, not all of the sun was completely obscured. Instead a nebulous region of plasma, called the corona, extends out into space and is not covered by the disc of the moon during totality. But, since the sun's primary surface is covered, some portions of the corona can be studied only during an eclipse. To exploit this fact a group of scientists set up teams across the US to take telescopic observations of the sun during totality.
