No, Leonardo has no “descendants”

July 18, 2021

The news spread quickly last week.

Fourteen people alive today in Italy can claim that they are descendants of Leonardo da Vinci, according to a study of the Renaissance genius’ family tree.

https://www.nbcnews.com/science/science-news/fourteen-living-descendants-leonardo-da-vinci-are-identified-rcna1402

I won’t bother posting the other two to three dozen “news” about it, since they all pretty much copy each other without doing much (or any) actual journalistic research.

Nor do they use common sense.

In the paragraph following the one quoted above, this sentence appears:

Researchers traced da Vinci’s genealogy over nearly 700 years and 21 generations, from 1331 to the present day, beginning with da Vinci’s great-great-great grandfather Michele.

OK. So this is family genealogy, not just Leonardo, right?

That would explain why so many people were found. But they’re his relatives, not descendants.

Da Vinci, best known for painting “The Last Supper” and “The Mona Lisa,” had no children, but his blood relatives include 22 half siblings.

If he had no children (which is true), then he has no descendants.

Simple.

Yet another case of media happily exaggerating studies they don’t understand but are eager to exploit.

Also, Leonardo always signed his name “Leonardo di Ser Piero” or “di Piero.” Vinci is a small town near where he was born. (People at that time period in Europe didn’t have surnames in the modern sense.) So saying the research is about the “da Vinci family” makes little sense. Nor does the idea that “genius” runs in families. The famous Edison dictum applies here.

I’m also fairly certain Leonardo had 12, and not “22,” half-siblings. Ser Piero was a bit indiscrete but not that indiscrete. He was a notary, not a king.

Dropping a shoutout to all my followers, old and new. Thanks for reading!

I’m preparing this week’s installment of Bringer of Light (Chapter 3, Part 2), all the while scouring the web for science and tech news to share.

Anything you want to see shared (or want to share)? Comments on the story so far? Something you want to rant about? (No politics please! Waaay too much of that at home right now. I’d rather keep my head in the stars when possible…)


Bringer of Light: Chapter 3, Part 2 – dropping at 7 p.m. EDT October 31st. No Halloween theme, sorry (that’s a separate post 🎃).

Meet Arisa, our local “inforobo”

This is Arisa, the “Information Robot.” It was recently installed at Yamato-Saidaiji, a Kintetsu Railway station in Nara City that I travel through to go to work.

Actually, today I went through the station on my way to renew my driver’s license. Interacting with the robot was much easier.

She (oops, I mean “it”?) can speak four languages (Japanese, English, Mandarin, and Korean) at the touch of a panel. But the functionality is still only limited to basic phrases about where to change trains and which platform to use. Still, it’s a first step (toward replacing human-controlled info booths, so get started learning programming, kiddos!).

The exciting world of regolith oxygen extraction

October 25, 2019

Future moon settlers might benefit from oxygen extraction from lunar regolith as it can be used to create breathable air as well as a source for fuel. In addition, the newly found extraction method might also be useful for Mars colonization.

Regolith covers the Moon and Mars (and presumably many other potentially habitable rocky bodies).

Of course, the composition of regolith on the Moon differs from that of Mars.

But if the new method can extract sufficient quantities of both oxygen and hydrogen, there should be ample amounts for both human usage and rocket fuel.

(Yawn.) “Dry” science? Sure. But think of the (fictional) possibilities!

Have Gravity Link Spaceship, Will Travel?

October 16, 2019

Youtuber smallstars has proposed a concept that he calls the Gravity Link Starship (GLS), a variation of SpaceX’s Starshipthat will be able to provide its own artificial gravity.

Hm, I guess we’re at the point where YouTubers have better ideas than NASA…

But who pays for this? is the several billion dollar question. Not just the construction of the “hub and truss” system, but the expense of getting it into space in the first place.

Seems like science fiction at this point. But still worth a read/look:

Winter is coming…well, not quite but

Sorry I haven’t posted anything in a while. I know it’s been about two months. Summer was filled with fun family activities in Montreal. September was filled with trips to libraries and feeling sorry for myself. Got into a bit of a funk.

Now I’m back in Japan, back to the daily grind, and trying to find time to sort out all the stuff I mailed back from Montreal.

Rest assured, there’s lots of stuff to write about. Some of it even makes sense.

I’ll be writing a few quick posts about various cool science and space things in the upcoming days. Then maybe a couple of longish ones about weird family history. And maybe even an update on my SF novel.

Yeah. I still didn’t finish the first draft. Stuck on 70,000 words. But the end is in sight!

More later…

What ever happened to May?

MThomas

One minute I’m blogging along, the next minute…
No, I don’t mean Theresa May, I mean the actual May…er, May, as in the month of. I missed the entire month of blogging!

Right. Well, I have some catching up to do. A few more interesting science tidbits, more about family history and possible story ideas for historical fiction (and/or fictionalized history).

And there’s that SF novel I keep meaning to finish…

More soon, I promise!

You must not go into the Wood at night!

Check out this free five-minute reading of “The Magic Wood,” by Henry Treece, one of many New Apocalypse poets who influenced Neil Gaiman’s dialogue in Sandman. Available only for the next 29 days.

Truly creepy. With Great Pleasure at Christmas (great title, BBC).
