The number of legal chess positions has now been estimated with 2 digits of accuracy as ~ 4.8 x 10^44: https://github.com/tromp/ChessPositionRanking For the game of Go, we know all 171 digits of the number: https://tromp.github.io/go/legal.htm

The 2nd link for go gives me a 404.

Sorry; misses an l at the end; should be https://tromp.github.io/go/legal.html

Harmonicas are amazing instruments. At first people assume them to be like toys (you can buy really cheap ones everywhere) and initially the concept seems really easy: 10 holes, drawing air produces some notes and blowing air produces other notes. But the more you get into it, the more amazing it gets. Soon you discover that you can bend notes by positioning your tongue in a specific way and your repertoire increases…

Fabulous addition. For anyone looking to see what a master harmonica player looks like, highly recommend looking up blues traveller / John Popper. In particular, there’s a live performance of no woman no cry that has John Popper alongside Ziggy Marley. Mind blowing. Watch it. You won’t regret it. https://youtu.be/9zk0HFG5mDw

This one is incredible!

it's useful and yet understanding how brain works precisely require better instruments and datasets hence the understanding of the brain is not bottlenecked on infinite complexity but before anything, on good old metrology. Q.E.D oh yeah well done completely avoiding the PNS question, so according to you neurons in the tail are relevant to worm cognition? spoiler except for tail local stimulus (e.g. tactile, heat) I…

QED is something you write after proofs not incomprehensible sentences. there is a compelling argument to be made that what neuroscience is missing is theory, not data. there is quite a lot of data. i am dissappointed, although not surprised that someone who relies on appeals to authority when arguing a point is of the mindset that in an organism so finely optimized that it uses biomechanical feedback in gait generat…

I will plainly repeat my citation from the previous c.elegans paper ""the inability to reliably identify all neurons within whole-brain recordings has precluded a full picture with circuit-level details."" and the lack of glutamate receptors mapping.

Those are sufficent to asses we are bottlenecked on data. We lack theories especially because we lack data. Yes of course we have a lot of data, which is useless without a complete picture. try debbugging a complex software with only partial, limited logging, the task become easily intractable. But it seems you are more interested in a clash than in sharing knowledge. My argumentation is sound and valid, which make it cogent, authority is unecessary to come to an agreement.

You probably don't have free will, you have no more control of the thoughts that motivate you to take action as you do the thoughts that do not.

Thank you everyone for commenting, you did so because you were compelled by forces that you don't control and thus, did not do so of your own free will.

On a serious note, Sam Harriss essay on free will is a good read, nihilism and existentialism too.

A point I'd like to make is that surrendering and accepting to things you don't control can bring you short term peace but will crush your long term peace. I personally don't care if I have or don't have free will, there are things about myself and the world around me that I cannot control but will never stop trying to fight against it. Hurting people, for one. I think that's my definition of free will.

Someone else made a point that free will could be similar to the god of the gaps theory, where free will is in the gaps.

For some reason German sometimes drops the i in "-isch" (cognate with English "-ish"). But the only reasonably common examples I can think of are Deutsch (etymologically definitely with -isch/-isk) and Kölsch ('pertaining to Cologne'). I don't know if this is somehow an example of a more widespread phonological process in German.

In Swedish, "isk" endings are sometimes contracted to "sk" such as "polsk"="polish" and the only way to say "pertaining to Köln" would be "kölsk" (unless specifically the beer.) But "människa" is a noun. It's pronounced "menisha" but it doesn't mean "manish". In Norwegian, the word for humane is spelled "menneskelig" literally "menneske-like". (In Norwegian the 'k' is hard.) As I can gather, the literal meaning in sa…

Wiktionary claims that "människa" does mean "manish" (and that it's a direct cognate with "mensch"):

https://en.wiktionary.org/wiki/Reconstruction:Proto-Germanic...

It's just that that etymology has become opaque to modern-day Germanic language speakers.

I suspect you are right when it comes to analog circuits, but they are definitely LTI in a typical digital implementation. I checked this by adding reverb+delay and delay+reverb to two copies of a track in REAPER. I inverted the phase of one, played them together, and they cancelled out.

I would be very surprised at that! I have no time currently but I can put together a example for you to illustrate what I mean if you’d like.

No stress, but yes, I am curious.

In "Magic the Gathering Old School 7 Points Singleton" you play the card game Magic the Gathering but only with cards printed in the first 2 years (93/94) and only maximum 1 copy of each in your deck. And power cards are limited to 7 points according to a table found here https://ligaoldschoolmadrid.wordpress.com/2021/03/25/7-point... A wonderful nostalgic way to play the game.

> and only maximum 1 copy of each in your deck Excluding lands, of course.

Yes, basic lands.

I wish Arena had a mode for that. It sounds like a lot more fun than the modes they currently have. I’m still a beginner in MtG, would you say the way you described is easier than modern Magic?

Call me old fashioned but for me Magic is something you play holding physical cards in your hand.

If I look at modern cards they don't feel like the same game. Digitally generated art, strange creatures "Social Climber"? and most of the cards has long complicated texts and many using complicated mechanics.

Compare those new cards to old classic cards like Black Knight: https://scryfall.com/card/leb/95/black-knight

Maybe it is nostalgia, I don't know. But for me the essence and spirit of Magic as a game is with the 93/94 cards.

The study of unidentified aerial phenomena (UFOs) and the acknowledgement of the extraterrestrial hypothesis (or extra dimensional) will become mainstream. https://www.gillibrand.senate.gov/news/press/release/gillibr... Soft disclosure has happened already via the USS Nimitz encounter. If UAPs are true, then the floodgates are open and will lead to a forced re-evaluation of other high strangeness phenomena (telepathy…

Unidentified aerial phenomena are just what as their name say: aerial phenomena that are unidentified. There are no aliens playing in the US sky
