How I learned how NOT to carry a shoulder bag to work

July 2, 2023
MThomas

Have you ever had surgery? What for?

Yeah, minor surgery. On March 3, 2020, I had a benign tumor the size of a gum ball removed from my left shoulder.

It had been created by repeated rubbing of my shoulder bag strap on sweaty skin. Or rather on sweaty shirt over sweaty skin. I walk half an hour back and forth the train station to my workplace each morning and evening, and the summers in Kyoto are hot hot hot.

So there I was lying on a surgeon’s bed, getting my shoulder skin snipped into three pieces and pried open. My blood pressure shot up to 190 at one point. The surgeons told me to relax.

Uh. Yeah. They didn’t tell me how close the tumor was to a major artery, but I could make an educated guess.

There was a cloth screen between my face and my shoulder so that I couldn’t see what they were doing. And of course they had numbed the entire area and I couldn’t move my left arm at all.

But it was an unpleasant experience. No pain, but I could of course still hear the clip clip clipping of scissors on skin. And I have an imagination.

(Fwiw I have written a short story based on getting my wisdom teeth taken out—also with local rather than general anesthesia—though I didn’t include the factoid that my root tips shot across the room like tiny cannonballs and were never found again).

Fortunately, the surgery was successful— they even showed me the tumor (it looked like a tiny blancmange, and now you’ll have that image in your mind next time you eat one). They even asked me if if wanted to keep it (um, no thanks).

And afterwards the scar was barely visible, so good a job they did with the stitches.

Two days after the surgery, we went into lockdown and had to wear masks everywhere.

Talk about good timing.

And another post to which I forgot to add a title…

In a few billion years, our aging Sun will run out of hydrogen fuel in its core and begin to swell, eventually engulfing Mercury, Venus, and probably Earth itself. Known as the red giant phase, this is a normal step in a mid-sized star’s life cycle, when it swells to hundreds of times its usual size. There are plenty of red giants in the night sky, but astronomers have never caught one in the act of swallowing its planets — until now.

Pack your stuff, folks…

The photo is an artist’s depiction btw. The article describes how the astronomer discovered that star was eating its own planet.

Chemical traces reveal first-generation stars

June 16, 2023

The link below includes a night sky in Montana, which makes little sense when the researchers were in Beijing and Honolulu…

“The first-generation star we observed has the potential to become the oldest star we have ever seen,” said Alexander Heger, a professor in the school of physics and astronomy at Monash University in Australia who was part of the research team. “It probably had only lived for 2 1/2 million years and then exploded.”

https://www.nbcnews.com/science/space/chemical-traces-offer-evidence-universes-earliest-stars-rcna88790

Oh, and it also was discovered to be 260 times the size of our own Sun…just as theorized.

More importantly, this involved scientists from three different countries (China, Japan, and Australia), sharing information and working together for science.

Imagine if that spirit of cooperation could be extended into other domains…

Subaru, how about you?

Plume of water seen on Saturn’s moon

May 31, 2023
MThomas

The record-breaking plume reached nearly 6,000 miles into space – covering the distance between Ireland and Japan – and poured water into the void at an estimated rate of 300 litres a second.

https://www.theguardian.com/science/2023/may/30/astronomers-see-6000-mile-water-vapour-plume-blasting-from-saturn-moon

Note that the water jetted out into space nearly 40 times longer than the actual size of the moon (about 500 in diameter, or as the Gurdian puts it “500-mile-wide” for those who forgot the meaning of “diameter).

Enceladus is probably the best bet for life elsewhere in the solar system due to its water — and while whipping around Saturn once per day, which is likely the reason for underwater volcanos and other vents that may provide the proper chemistry for life.

Also the perfect place to trick an inexperienced asteroid hunter crew…

Only an hour to Manhattanhenge!

May 30, 2023
MThomas

Manhattanhenge, a portmanteau of “Manhattan” and “Stonehenge,” is a twice-a-year solar event when the sunset lines up directly with the city’s grid, casting golden rays down city streets. Several of the stones in Stonehenge, the prehistoric monument in Wiltshire, England, experience perfect alignment with the sun during the summer and winter solstices, which is why the event takes its name from the rock formation.

https://www.nbcnews.com/science/science-news/memroial-day-manhattanhenge-expected-light-new-york-city-streets-rcna86698

If you miss it today, don’t fret: it happens again in July during MLB’s All-Star Break.

And the next day after each “half-sun” event, you can still see the “full-sun” version. Anybody in NYC?

Betelgeuse! Betelgeuse! Betel…

May 26, 2023

Betelgeuse, the closest red giant to Earth, has long been understood to move between brighter and dimmer in 400-day cycles. But from late 2019 to early 2020, it underwent what astrophysicists called “the great dimming”, as a dust cloud obscured our view of the star.

Now, it is glowing at 150% of its normal brightness, and is cycling between brighter and dimmer at 200-day intervals – twice as fast as usual…It is currently the seventh brightest star in the night sky – up three places from its usual tenth brightest.

https://www.theguardian.com/science/2023/may/26/its-new-territory’s-why-is-betelgeuse-is-glowing-so-brightly-and-behaving-so-strangely?

Betelgeuse is the closet red giant Star to our solar system, one of the shoulders of the Greek constellation of Orion.

The cultural information in the linked article was actually more interesting than the phenomenon observed. For instance, the fact that an Aboriginal people in Australia saw it long before the Greeks did was something I didn’t know.

(Although ancient humans in what is now Germany apparently carved an image of it around 32,000 years ago…)

And that the Greek name comes originally from the Arabic “bat al-jawzāʾ” meaning “giant’s shoulder.”

And all three cultures saw the star as connected with fire held by a giant hunter of some sort.

And so have ancient Babylonians, Egyptians, and probably everyone else, too. We just can’t help personifying even the stars.

The kicker?

When it does eventually explode, it could – over the course of a week – grow so bright that it will be visible during daylight, and cast shadows at night.

Now that’s something I’d like to be around to see. Hmm. If only I could manage to live for another 10- to 100,000 years…

And today’s random writing prompt is…

Have you ever broken a bone?

Depends on how you define “broken.”

I got two bone spurs, separated by two years, thanks to playing baseball in junior high school. Both were fingers on my left hand.

The first time was my left thumb first joint. The second time was my left hand ring finger second joint.

Both times, our local health clinic doctor put a metal splint on the finger, wrapped it in flexible bandage and sealed it off with a tiny metal clip.

And of course I stupidly went on playing baseball, because at age 15 guys think they are completely indestructible.

My ring finger stuck out when I batted. I’m lucky I didn’t get hit by a pitch in the hand (I did get hit on the knee, but that’s a whole ‘nother story).

Also, it inspired my baseball novel. So there was a silver lining!

Cancel your asteroid insurance – for the next thousand years

Does anybody remember Spirographs?

Of all the asteroids they modeled, the one with the largest risk of impact was a kilometer-wide asteroid known as 1994 PC1. Over the next thousand years, the probability that 1994 PC1 will cross within the orbit of the Moon is a paltry 0.00151%, hardly worth worrying about.

Thanks to Glen Hill over at Engagin’ Science (formerly Scientia, which apparently was far too Latin- and science-esque for search engines to handle) for bringing this (not-so Earth-shattering) info to my attention.

Sorry, folks. Hollywood was once again wrong (sigh).

Largest cosmic explosion ever witnessed

Fireball ‘100 times the size of the solar system’ thought to have been caused by gas being sucked into supermassive black hole

https://www.theguardian.com/science/2023/may/12/astronomers-capture-largest-cosmic-explosion-ever-witnessed

Fortunately, this is about 8 billion light years away.

But it’s been going for over three years now.

Yow.

A taste of Scientia

May 5, 2023
MThomas

The word has just come in that a fellow traveler has set up his own blog about science.

It’s called Science.

(In Latin, Scientia.)

Glen is a good friend of mine, and not only is he a good scientist, he’s also a good writer. His avowed goal is to raise science literacy and share his love of science with the world.

We may even steal posts from each other from time to time. Or photos (like the one above ⬆️🌏).
