New Discoveries About Knots Boost Mathematicians' Case for Studying Them
Knots are usually a subject that students master by about first grade, when they graduate from Velcro-strapped sneakers.
For a small group of elite university mathematicians, however, the subject still holds endless fascination, and now, an important set of new discoveries even carry the possibility of advancing medical research.
The innovation concerns what's known as "virtual" knots. As the name implies, such knots can't necessarily be found in the
