A pair of light waves - one zipping clockwise the other counterclockwise around a microscopic track - may hold the key to creating the world's smallest gyroscope: one a fraction of the width of a human hair. By bringing this essential technology down to an entirely new scale, a team of applied physicists hopes to enable a new generation of phenomenally compact gyroscope-based navigation systems, among other intriguing applications.
"We have found a new detection scheme that may lead to the world's smallest gyroscope," said Li Ge, a physicist at the Graduate Center and Staten Island College, City University of New York. "Though these so-called optical gyroscopes are not new, our approach is remarkable both in its super-small size and potential sensitivity."

It's the gift shop where you can source your reality wizard skills. The kind that doesn't rely on either software, hardware or the good will of lawmakers (crooks). It's the assembler code of the universe and can really change things. Modifying or exploiting new properties of the basic matter or force field can enable really neat things.
A degree is just a key that makes your university career or employee career happy. The universe could not care less. It's only affected by what you actually do (absolute truth if you will). If you design a working flying mat. I promise no-one will bother with your papers..
