Ike Eisenhower was born #OTD 14 October 1890. Below is one of my favorite quotes. See the link for more insights from other prominent veterans on science, reason, and conservation.

Europa Clipper: Exploring Jupiter’s Ocean Moon (Mission Overview)
YouTube video by NASA Jet Propulsion Laboratory Europa Clipper: Exploring Jupiter’s Ocean Moon (Mission Overview)

One problem, though: that water is beneath several miles of ice. Future missions will depend on what Clipper can learn about this environment. You can learn more in this short video from NASA:

Clipper was launched 1 year ago and will arrive in 2030. One of Jupiter's moons, Europa, likely has vast oceans that *might* have life. 1/2

Another ghoul that haunts reasoning is the ad hoc rescue. See the link for more on what this is, is not, and more.

Our frightening fallacy series continues with the guilt by association fallacy. For more on what this fallacy is, is not, examples, and more, see the link.

Next on our Hallowen-themed look at fallacies is the ever-frightening fallacy fallacy. Sometimes, a conclusion is correct (or useful, good, viable, etc., depending on whether the argument is one of fact, definition, value, policy, etc.), but not because of that line of reasoning.

#OTD The physicist Niels Bohr was born (Oct 7, 1885). He is most famous for developing the Bohr model of atomic structure, for which he earned the Nobel Prize in 1922. So, I guess science didn't find his discoveries "Bohring."

Did the joke fall flat? Well, pobody's nerfect.

Sure, the special pleading fallacy is a killer mistake, but I only used it to avoid the nightmare of losing an argument.

Don’t let fallacies haunt your arguments. Critical thinking can cast them back to hell, where they belong. So, see the link for more.

Some people say middle ground fallacies are spooky. Others say they’re spectacular. But they’re obviously spooktacular.

In all seriousness, see the link to learn more about what this fallacy is, what it is not, and more.

Dr. Robert H. Goddard, American Rocketry Pioneer - NASA Dr. Robert Hutchings Goddard (1882-1945) is considered the father of modern rocket propulsion. A physicist of great insight, Goddard also had a unique genius

As a bona fide space nerd, I love this quote. May we live up to his vision.

Sadly, even though he dedicated years of his life to this endeavor, he died before he could see humanity take its first steps into space. Below is a sentiment he shared in a letter to the legendary science fiction writer, H.G. Wells.

Anyway, Dr. Goddard was a pioneer in the development of liquid-fueled rockets. By figuring out how to launch such contraptions into the heavens without killing himself, he laid the foundation for space exploration. Hell yeah.

I almost forgot to post this. #OTD in 1882, the OG rocket scientist, Robert H Goddard, was launched into this Earth and he spent the rest of his life trying to figure out how to get off this planet. (Can't blame him).

Learning to spot untestable claims pleases the spirit of Carl Sagan. Anyway, see the link for more on this group of fallacies. You're free to refuse, of course. But if you do, a star will blow up at an unspecified time and place.

Correlation & Causation Sure, many correlations are not due to causation, but causation requires some kind of correlation. So the question stands… how do we infer causation? The short answer is, β€œIt’s co…

But a more helpful answer is in the link. Hopefully, reading the article will cause more learning. But then again, a Marine grunt wrote this, so who knows.

Spooky for sure. While it's true that correlation β‰  causation, we can't just ignore every correlation... so... 𝘩𝘰𝘸 𝘀𝘒𝘯 𝘸𝘦 confidently infer causation?

The short answer is, "It's complicated."

The longer answer? "It's most definitely cooompliiiiiiiiiicaaaaaated."

US justice department removes study finding far-right extremists commit β€˜far more’ violence Report finding rightwing extremists have killed more Americans than other domestic terrorist groups vanished from DoJ website

Interestingly, the report was removed from the DOJ website after Kirk's death. Why do you think that is? Even if the stats were reversed, I would want to know. I wouldn't want my government to hide it.

1: Don't believe the lies that political violence is a leftist problem. (*cough* Jan 6 *cough*)

2: Yup, it’s a problem on both extreme ends, but it's substantially lopsided

3: This doesn't mean the average conservative is an extremist

4: This doesn't excuse Kirk's killer
