The molecular hydrogen ion H₂⁺ is the simplest molecule. This simplicity makes it a perfect study object for physicists, as its properties—for example, its energy levels—can be calculated precisely. In turn, this enables theoretical predictions to be compared with experimental measurements to determine whether the theories reflect reality correctly. ... Read full Story

Stress is a very real factor in the structure of our universe. Not the kind of stress that students experience when taking a test, but rather the physical stresses that affect everyday objects. Consider the stress that heavy vehicles exert on a bridge as they cross over it—it's essential that engineers understand and consider this factor when designing new trestles. Or consider the stresses that a star experiences—this internal factor influences everything from its shine to its lifetime. ... Read full Story

“This isn’t new territory for the band—beginning with 2018’s Modern Meta Physic, Peel Dream Magazine have taken cues from bands like Stereolab and Pram, exploring the ways that rigid, droning repetition can make time feel rubbery. As they snap back into the present, Black sings, ‘Millions of light years, all of them ours.’ The past and future fold into themselves, braided together in perpetuity.” — Dash Lewis, Pitchfork, 4 Sept. 2024
Did you know?
Perpetuity is a “forever” word—not in the sense that it relates to a lifelong relationship (as in “forever home”), but because it concerns the concept of, well, forever. Not only can perpetuity refer to infinite time, aka eternity, but it also has specific legal and financial uses, as for certain arrangements in wills and for annuities that are payable forever, or at least for the foreseeable future. The word ultimately comes from the Latin adjective perpetuus, meaning “continual” or “uninterrupted.” Perpetuus is the ancestor of several additional “forever” words, including the verb perpetuate (“to cause to last indefinitely”) and the adjective perpetual (“continuing forever,” “occurring continually”). A lesser known descendent, perpetuana, is now mostly encountered in historical works, as it refers to a type of durable wool or worsted fabric made in England only from the late 16th through the 18th centuries. Alas, nothing is truly forever.
