Particles Larger Than Galaxies Fill the Universe?

Observation of a neutrino hitting a proton in ...

‘The oldest of the subatomic particles called neutrinos might each encompass a space larger than thousands of galaxies, new simulations suggest.

Neutrinos as we know them today are created by nuclear reactions or radioactive decay.

According to quantum mechanics, the “size” of a particle such as a neutrino is defined by a fuzzy range of possible locations. We can only detect these particles when they interact with something such as an atom, which collapses that range into a single point in space and time.

For neutrinos created recently, the ranges they can exist in are very, very small.

But over the roughly 13.7-billion-year lifetime of the cosmos, “relic” neutrinos have been stretched out by the expansion of the universe, enlarging the range in which each neutrino can exist.

“We’re talking maybe up to roughly ten billion light-years” for each neutrino, said study co-author George Fuller of the University of California, San Diego.

“That’s nearly on the order of the size of the observable universe.” ‘ (National Geographic)

Is Slam in Danger of Going Soft?

“Slam poetry was invited into the White House last month and it is also the focus of the recent HBO documentary series “Brave New Voices.” So you might think that the originator of the poetry slam, a raucous live competition that is more likely to take place in a bar than in a bookstore, would be feeling rather pleased these days.

But from his base here at the Green Mill Cocktail Lounge, Marc Kelly Smith expresses mixed feelings about the growing popularity and respectability of the art form that he created almost 25 years ago. From the start, he envisioned slam poetry as a subversive, thumb-your-nose-at-authority movement, and he wants to ensure it stays true to those origins.” (New York Times )

Sai...BLUSHING!!

“We are this hypersocial species that settles conflicts and misunderstandings face to face, and we need a way to repair daily betrayals and transgressions quickly…”

In a series of recent studies, psychologists have found that reddening cheeks soften others’ judgments of bad or clumsy behavior, and help to strengthen social bonds rather that strain them. If nothing else, the new findings should take some of the personal sting out of the facial fire shower when it inevitably hits.’ (New York Times )

Bob Herbert: “One can only hope that the hysterical howling of right-wingers against the nomination of Sonia Sotomayor to the Supreme Court is something approaching a death rattle for this profoundly destructive force in American life.” (New York Times op-ed)

I just discovered, serendipitously, that my neighbor Ed Bonfilio is an accomplished, and exhibited, painter. Here is an oil he did of a house on our street in Brookline.
