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.

mRNA and nanotech? Stay skeptical and use the Baloney Detection Kit!

It’s becoming increasingly common to see social media posts claiming that the mRNA COVID-19 vaccines, which include those made by Pfizer and Moderna, could alter a person’s DNA. Some posts even suggest that nano-machines are being injected into the body.

https://cosmosmagazine.com/health/covid/technically-no-longer-human-can-mrna-covid-19-vaccines-meld-with-your-dna/

Yeah, I’ve seen some of these posts. Talked to a neighbor who was convinced Bill Gates was trying to inject us all with a chip to control our minds.

Is there any truth to these rumours? Could an mRNA vaccine be modifying your DNA?

No.

(Read the linked Cosmos article for more details!)

Actually, all you need to do is use logic and reasoning, apply some critical thinking, and demand lots of science-based evidence.

It’s called the Baloney Detection Kit and was introduced in a Cornell University undergraduate course about critical thinking and the scientific method by astrophysicist Carl Sagan.

In his book The Demon-haunted World, he lays out nine steps to bust BS and call out unscientific baloney. I use it with my second year undergrad students in a current news and global issues course.

The link above to the kit also outlines some of the most important logical fallacies to avoid, with number 8 and 9 being the most difficult to explain and convince people about (because they involve education about basic statistics).

So will this convince anti-vaxxers who make outlandish claims online?

Probably not. Unless it goes viral 😉.

Sorry, Venus is just a lot of gas

There’s a reason I didn’t post a while ago about the supposed “there’s life in the clouds of Venus” finding.

It was just a big load of gas.

Sorry, folks. Venus is a big rotten egg. 🥚

No, it’s not actually an iPhone. Yes, please stop the sloppy reporting, thanks

This is already a few months old, but I thought I’d finally get around to blogging about it: The “ancient iPhone” of “Russia’s Atlantis.”

Spoiler alert: it’s not one, and there was no such place. But that didn’t stop the “news” from spreading. Continue Reading

ESA and NASA? Airbus? Still not ready? 🤦‍♂️

Right now, engineers have got a dummy rover practising the business of retrieving packaged rock samples. And, yes, the stand-ins really are whiteboard markers.

Yay! Whiteboard markers. Um. OK.

But different agencies and companies are finally working together?

Great!

Wait. What’s the catch?

It is, though, going to take more than a decade to achieve.

Sigh.

No, the “golden asteroid” will NOT make you rich

I wrote about this a couple of days ago (based on an article from two weeks prior), but it’s interesting to see random websites suddenly jumping on the “we’ll all get rich!” asteroid mining band wagon. Hey, everybody, let’s copy-paste stuff and not use our brains!

A new article by rt.com even includes two click-bait links to “how gold was formed” that have nothing whatsoever to do with NASA’s probe to (16) Psyche. Of course, we shouldn’t expect any less from an obvious Russian “news” distributor. But in the interests of calling out the bad reporting in this and similar “news” articles spread online recently, let’s give this a hearty smack-down.

Aliens are among us! Um, apparently…

Still, the fact that someone as highly educated as Chi wrote an entire book based on salvation by extraterrestrials could be a sign of how daunting our future is starting to look.

Or, conversely, how wack some Oxford dons really are…

The Stainless Steel Musk Strikes Again!

He described the concept as a “stainless-steel sandwich” that can “bleed water…fuel” through tiny holes on its surface to keep it cool as it enters the Martian atmosphere at breakneck speeds.

Not sure, but I don’t think there are a lot of people who want to travel to Mars inside a sandwich…

Two of the greatest Science Fiction authors of all time, were both born on this day December 16 – Arthur C. Clarke in 1917 and Philip K. Dick in 1928.

Note that I always put “Sir” in quotes, because, basically, $%# that BS. Clarke may have conceived of (NOT invented) the satellite, but PDK (NOT a “Sir”) has had infinitely more influence on modern society.

So I’m calling PKD “Esq.” Also a Pope. Remember that “All statements are true in some sense, false in some sense, meaningless in some sense, true and false in some sense, true and meaningless in some sense, false and meaningless in some sense, and true and false and meaningless in some sense.” Hail Eris!

Anyway, thanks to blackwings666 for the reminder…
