Isaac Asimov dubbed neutrinos “ghost particles.” John Updike immortalized them in verse. They’ve been the subject of several Nobel Prize citations, because these weird tiny particles just keep surprising physicists. And now we have a much better idea of the upper limit of what their rest mass could be, thanks to the first results from the Karlsruhe Tritium Neutrino experiment (KATRIN) in Germany. Leaders from the experiment announced their results last week at a scientific conference in Japan and posted a preprint to the physics arXiv.

“Knowing the mass of the neutrino will allow scientists to answer fundamental questions in cosmology, astrophysics, and particle physics, such as how the universe evolved or what physics exists beyond the Standard Model,” said Hamish Robertson, a KATRIN scientist and professor emeritus of physics at the University of Washington…

Physicists get small: “Weighing in: Physicists cut upper limit on neutrino’s mass in half.”

As we step onto the scales, we might spare a thought for Max Karl Ernst Ludwig Planck; he died on this date in 1947.  A theoretical physicist, he is best remembered as the originator of quantum theory.  It was his discovery of energy quanta that won him the Nobel Prize in Physics in 1918.

“Humanize your talk, and speak to be understood”*…

Personification is weird…yet entirely natural. It’s the odd practice of pretending things are people. When we personify, we apply human attributes to inanimate objects, to nature, to animals, or to abstract concepts, sometimes complete with dramatic stories about their social roles, emotions and intentions. We can observe this linguistically through features like unexpected pronoun use or certain animate verbs and adjectives that are usually only applied to people. A common example is how ships and other vessels traditionally have a feminine gender in English (even if the ship happens to be a “man-of-war“)… There’s a strange empathy in words like “she is alone” applied to an object that can’t possibly have a sense of loneliness. This isn’t the artifice of poetry, but everyday language. On the face of it, the concept of personification seems pretty crazy, the stuff of fantasy and magical thinking…

You might think, like many a respectable scientist, that it has no place in our earth logic, because not only is it not real, it is objectively false (and therefore unscientific), since inanimate objects do not have feelings or intentions (and if animals do, we can’t possibly know for sure). Yet personification is not only wildly popular in language use (even if we don’t always notice it), it’s a fascinating psychological phenomenon that reveals a lot about social cognition and how we might understand the world…

How the way we talk about the things around us both shapes and reflects our understanding of the world: “Personification Is Your Friend: The Language of Inanimate Objects.”

As we muse on anthropomorphic metaphor and meaning, we might recall that today’s a relative-ly good day for it, as it was on this date in 1900 that German physicist Max Planck presented and published his study of the effect of radiation on a “black-body” substance (introducing what we’ve come to know as the Planck Postulate), and the quantum theory of modern physics– and for that matter, Twentieth Century modernity– were born.

Planck study demonstrated that in certain situations energy exhibits the characteristics of physical matter– something unthinkable at the time– and suggested that energy exists in discrete packets, which he called “quanta”… thus laying the foundation on which he, Einstein, Bohr, Schrodinger, Dirac, and others built our modern understanding.

As we fixate on fact-checking, we might recall that this is the birthday of quantum physics: it was on this date in 1900 that Max Planck published his study of the effect of radiation on a “blackbody” substance, demonstrating that in certain situations energy exhibits the characteristics of physical matter– something unthinkable at the time– and suggesting that energy exists in discrete packets, which he called “quanta”… thus laying the foundation on which he, Einstein, Bohr, Schrodinger, Dirac, and others built our modern understanding of physics.

The most unkindest cut…

Your correspondent has long been haunted by a question of practical fairness:  Suppose I order a pizza to share with a friend, and then a distracted waiter cuts the pie off-center, but with all the edge-to-edge cuts crossing at a single point, and with the same angle between adjacent cuts. The off-center cuts mean the slices will not all be the same size, so if my friend and I take turns to take adjacent slices, will we get equal shares by the time we’ve finished the pizza– and if not, who will get more?

Happily, this question also bothered mathematicians Rick Mabry and Paul Deiermann, who set out to answer it.  And, as the New Scientist reports, answer it they did.   Readers can henceforth consult this handy diagram…

The full story is here.

(And for info on how to cut a bagel so that it forms [in effect] a Möbius strip, see “Mathematically Correct Breakfast.”)

As we reach for the crushed red pepper, we might recall that today’s a relative-ly good day for a pizza party, as it was on this date in 1900 that German physicist Max Planck presented and published his study of the effect of radiation on a “black-body” substance (introducing what we’ve come to know as the Planck Postulate), and the quantum theory of modern physics– and for that matter, Twentieth Century modernity– were born.
