To wear the Icebreaker Quantum Headband, you don't have to fully understand how what was thought of as five different string theories turned out to be one string theory. You also don't have to have all 11 dimensions worked out. All you really need is a slightly chilly forehead. Merino wool naturally regulates your body temperature and deals with odor so you can wear this headband day after day during the physics conference or, more likely, during your ski vacation.
