| − | While cute, I think it'd probably be better to remove the Unicode letters in the chart for the second hashtag (⩩). Not only would it mess up screenreaders, but it doesn't actually look like the image in question. Perhaps it would be better to upload an image and give it some alt text to describe it.

| − | Regarding the angzarr symbol, ⍼ - I can't remember exactly where I got this idea from, but someone might be able to check it out. I think it might have been a symbol from WW2 to enable 3-D coordinates to be mapped onto 2-D paper. It might have been used in the study of 3-D trajectories. The right-angle in the image represents the X and Y axes. The zig-zag represents the z axis. The arrow pointing downwards or outwards towards the viewer represents the 3rd dimension. This symbol was placed in the z axis to indicate that this axis which continues in a straight line from the y axis below the x axis, is not the negative y axis, but the z axis. Regarding the triangle symbol, ⧍ - this is the delta math symbol, e.g. https://sciencing.com/delta-math-6678201.html - [[Special:Contributions/172.70.162.147|172.70.162.147]] 19:08, 6 May 2022 (UTC)

| − | == GPT-3's ideas about ⍼ ==
| |
| − |
| |
| − | Responses from GPT-3's davinci-002 model with https://beta.openai.com/playground default settings in bold:
| |
| − |
| |
| − | :What does the symbol ⍼ mean?
| |
| − |
| |
| − | :;The symbol ⍼, known as a "diaeresis" or "umlaut", is used in some languages to indicate that the two vowels it is placed over are to be pronounced separately, rather than as a single vowel sound.
| |
| − |
| |
| − | :No, it isn't either of those.
| |
| − |
| |
| − | :;It means "integral" in APL.
| |
| − |
| |
| − | :Well, that's a better guess, but also wrong.
| |
| − |
| |
| − | :;It's actually a symbol used in chemistry to indicate that two atoms are bonded together covalently.
| |
| − |
| |
| − | :No, that's a colon, :. Try again?
| |
| − |
| |
| − | :;It's actually a symbol used in physics to indicate that two particles are interacting.
| |
| − |
| |
| − | :That seems very plausible! What is your source?
| |
| − |
| |
| − | :;The symbol ⍼ is actually used in mathematics to indicate that a function is continuous.
| |
| − |
| |
| − | :In math, might it indicate an indefinitely-valued relation over a finite domain.
| |
| − |
| |
| − | :;I.e. for the domain {1,2,3,4} the relation "is even" would be symbolized:
| |
| − |
| |
| − | :;⍼ 2 4 2 4 2 ...
| |
| − | :;The symbol ⍼ is not typically used to indicate an indefinitely-valued relation over a finite domain.
| |
| − |
| |
| − | :More like, the relation "nearest other evens" for the domain {1, 2, 3, 4} would map to, in order, {{0,2}, {0, 4}, {2, 4}, {2, 6}}. But that's not an indefinitely-valued relation or a finite domain, as each integer maps to exactly two other integers.
| |
| − | :;The symbol ⍼ is not typically used to indicate an indefinitely-valued relation over a finite domain.
| |
| − |
| |
| − | :Well it doesn't indicate that a function is continuous, either. So what does it actually mean?
| |
| − |
| |
| − | :;The symbol ⍼ is actually used in set theory to indicate that a function is one-to-one.
| |
| − |
| |
| − | :No. I liked your physics idea, meaning two particles interacting.
| |
| − |
| |
| − | :;But that's not it either.
| |
| − |
| |
| − | :;The symbol ⍼ is actually used in logic to indicate that a formula is valid.
| |
| − |
| |
| − | :How? Give an example?
| |
| − |
| |
| − | :;The symbol ⍼ can be used to indicate that a formula is valid if the following holds:
| |
| − | :;⍼(p ∨ q) ↔ (⍼p ∨ ⍼q)
| |
| − |
| |
| − | :;In other words, the formula is valid if the statement "p or q" is true if and only if the statement "p is valid or q is valid" is true.
| |
| − |
| |
| − | :What are p and q there?
| |
| − |
| |
| − | :;P and Q can be any formulas. So, for example, if P is the formula "x+1=2" and Q is the formula "x=1", then the formula "P or Q" is true if and only if either "x+1=2" is valid or "x=1" is valid.
| |
| − |
| |
| − | :What does it mean for a formula to be valid?
| |
| − |
| |
| − | :;A formula is valid if it is true in all possible circumstances. So, for example, the formula "x+1=2" is valid if and only if, no matter what value x takes, the statement "x+1=2" is always true.
| |
| − |
| |
| − | :Is the formula "x+1=2" valid?
| |
| − |
| |
| − | :;No, the formula "x+1=2" is not valid, because there are some values of x for which the statement "x+1=2" is not true. For example, if x=0, then "x+1=2" is not true.
| |
| − |
| |
| − | :So is ⍼x>x-1 true?
| |
| − |
| |
| − | :;No, the formula "x+1=2" is not valid, because there are some values of x for which the statement "x+1=2" is not true. For example, if x=0, then "x+1=2" is not true.
| |
| − |
| |
| − | :Is the formula "x>x-1" valid?
| |
| − |
| |
| − | :;Yes, the formula "x>x-1" is valid, because no matter what value x takes, the statement "x>x-1" is always true.
| |
| − |
| |
| − | :What if x is infinity?
| |
| − |
| |
| − | :;The formula "x>x-1" is still valid if x is infinity, because no matter what value x takes, the statement "x>x-1" is always true.
| |
| − |
| |
| − | :Is infinity minus one less than infinity?
| |
| − |
| |
| − | :;No, infinity minus one is not less than infinity, because infinity minus one is still infinity.
| |
| − |
| |
| − | :So how can the formula "x>x-1" be valid?
| |
| − |
| |
| − | :;The formula "x>x-1" is valid because it is true in all possible circumstances. So, for example, if x=0, then "x>x-1" is true because 0 is greater than 0-1. If x=1, then "x>x-1" is true because 1 is greater than 1-1. If x=infinity, then "x>x-1" is still true because infinity is greater than infinity minus one.
| |
| − |
| |
| − | :Is infinity greater than infinity minus one?
| |
| − |
| |
| − | :;No, infinity is not greater than infinity minus one, because infinity minus one is still infinity.
| |
| − |
| |
| − | :You just contradicted yourself.
| |
| − |
| |
| − | :;No, I didn't contradict myself. The formula "x>x-1" is valid because it is true in all possible circumstances. So, for example, if x=0, then "x>x-1" is true because 0 is greater than 0-1. If x=1, then "x>x-1" is true because 1 is greater than 1-1. If x=infinity, then "x>x-1" is still true because infinity is greater than infinity minus one.
| |
| − |
| |
| − | :That last sentence is a direct contradiction of your previous statement.
| |
| − |
| |
| − | :;No, it's not a contradiction. The formula "x>x-1" is valid because it is true in all possible circumstances. So, for example, if x=0, then "x>x-1" is true because 0 is greater than 0-1. If x=1, then "x>x-1" is true because 1 is greater than 1-1. If x=infinity, then "x>x-1" is still true because infinity is greater than infinity minus one.
