The Who Need

Several years ago, the scientist Michael Bang Petersen… wanted to understand why people share on the Internet. He & other researchers designed a study that involved showing participants blatantly false stories about & , such as , , , & Donald .

The results seemed to defy of modern or . “There were many…who seemed willing to share any , regardless of the party…,” Petersen said. These participants didn’t seem like stable partisans of the left or right. They weren’t even negative partisans, who hated 1 side w/o feeling allegiance to the other. Above all, they seemed drawn to stories that undermined in every system of .

If you struggled with the traditional textbooks .. this short course was developed just for you.

✅ Develop understanding through hands-on bite-size examples.

✅ Example code is minimal to avoid distraction.

✅ Talk through how new ideas work, step-by-step.

✅ Avoid terminology and jargon if it is likely to hinder more than help.

Just musing on the concept of fallacies --

So a is defined by how the conclusion was arrived at, not what the conclusion actually is. Any conclusion that was arrived at through fallacious reasoning, is a logical fallacy.

However, that only proves that the conclusion is illogical, it doesn't prove that the conclusion is logically false.

Right?

Most of us agree that

P ⇒Q

is the same as

"If P is true, then Q is true"

But I can't see how it is also the same as

"P only if Q"

Help! 😵‍💫

I personally way prefer outcomes!

'Magical' Error Correction Scheme Proved Inherently Inefficient

Locally correctable codes need barely any information to fix errors, but they’re extremely long. Now we know that the simplest versions can’t get any shorter.

Rogers's Equivalence Theorem (https://en.wikipedia.org/wiki/Admissible_numbering#Rogers'_equivalence_theorem) is more amazing than it sounds.

(Plus a question about it at the end)

It says that any two admissible numberings (aka programming languages: https://en.wikipedia.org/wiki/Numbering_(computability_theory)) of the partial computable functions are computably isomorphic.

To see how amazing this is: it's standard that you can write a program to compile Python programs to Java programs and vice versa. Just from those two compilers, Rogers's Equivalence Thm implies that there is a total computable function f that transforms Java programs into input-output-equivalent Python programs that is 1-to-1 (not so surprising) and onto - every Python program arises as f(p) for some Java program p, and p and f(p) compute the same function. That is pretty surprising!

Now the Q: Shouldn't there be some analagous theorem for Gödel numberings? Sure, they're not unique (https://en.wikipedia.org/wiki/G%C3%B6del_numbering#Lack_of_uniqueness), but isn't there a sense in which "all reasonable Gödel numberings are isomorphic"?

If mapping arguments improves critical thinking, then argument mapping skills should correlate with critical thinking skills, right?

Alas, they didn't correlate among 115 Advanced Placement students across 4 high schools who mapped arguments for universal basic income (from a Douglas Murray article).

British mathematician and philosopher Bertrand Russell died in 1970. He was one of the early 20th century's most prominent logicians and a founder of analytic philosophy, along with his predecessor Gottlob Frege, his friend and colleague G. E. Moore, and his student and protégé Ludwig Wittgenstein. Together with his former teacher A. N. Whitehead, Russell wrote Principia Mathematica. via @wikipedia

I've talked before about how some default metronome sounds are stupid.
, ... Just go home. Go home, stay at home and don't let anyone have to hear that shower singing noise. Kill it with fire. Or water as the case may be.

... Where you going with that? You can't leave the house with that stupid click. Get to your room!

... Reaper... What? Just no. Don't even look at me like that, you know you're just wrong. Stop it. Don't!

... Finally someone I'm not embarrassed to be seen with. Well done, well done.
... Yep, you ain't half-bad either. Good. Proud of you.

Sure, you can make others behave nicer, but why are so many default metronomes just such a pile of shite?

Who else likes logic grid puzzles like these ones? https://www.brainzilla.com/logic/logic-grid/

I had a teacher who loved them. Sometimes she’d give us one to work on. After a while, she’d put up that same puzzle on the projector and explain how to solve it for anyone who didn’t find all of the answers.

Her enthusiasm for them made me a lifelong fan of them, too.

Does anyone have recommendations for a good beginners midi controller that's fairly cheap, ideally a 25-key one? I don't want to break the bank just yet, but I'm getting incredibly tired of Musical Typing and trying to play complex melodies on a MacBook's internal keyboard.
