(Phys.org) -- Can light self-bend into an arc? Can shape-preserving optical beams truly bend along a circular path? A confident answer emerged in this week’s Physical Review Letters.

The founder of Joie de Vivre hotels on his new book, Emotional Equations, and the trick he uses to combat paralyzing anxiety. Chip Conley knows fear. In 2008 with the economy in recession, his hotel business Joie de Vivre sinking around him, a family member wrongly convicted and in San Quentin prison, five close friends recently lost to suicide—his heart just stopped

Knowing how to control the combined magnetic properties of interacting electrons will provide the basis to develop an important tool for advancing spintronics: a technology that aims to harness these properties for computation and communication. As a crucial first step, Naoto Nagaosa from the RIKEN Advanced Science Institute, Wako, and his colleagues have derived the equations that govern the motion of these magnetic quasi-particles.

Next time youre feeling down or anxious, stop feeling hopeless and do some math. Seriously. Chip Conley , the founder of Joie de Vivre , the second-largest boutique hotel company in the U.S., is the author of the just-released Emotional Equations: Simple Truths for Creating Happiness + Success .

For the mathematically challenged: A Web tool that sifts through your numbers and spots trouble for you. Math is not my friend , even though we did have a long-term relationship throughout my formative years. (If you’re reading this, Fourier Analysis and Partial Differential Equations, don’t forget: You didn’t dump me, I dropped you.) Accounting isn’t my friend either
