Time for a Mathematical Joke.

An Infinite Set of Mathematicians enter a Bar:

The lead one says I will have a Pint. The second one says I will have a half-Pint. The third one says I will have a quarter Pint.

The Barman is growing weary. He says "I know the answer to this. I am serving up two Pints, and you can sort it out for yourselves." 😀

Not being a mathematician, I sought out the mathematical basis of your joke. Here it is for any other non-mathematicians who frequent the thread.

"In the infinite series 1 + 1/2 + 1/4 + …, note that the numbers we are adding together are getting smaller. In fact, they are getting smaller sufficiently quickly that there is a number that they will get infinitely close to, but never reach. That value is 2. That means that the series converges to the value 2. It will never actually reach it, but it will always get closer to 2, and will get really, really close (i.e., infinitely close)."

Not being a mathematician, clever as I am, I did surmise the direction of the WIKI. However, please do explain where the 'humour' is.
 
Does the vernacular not suggest this?

What has the language or dialect spoken by the ordinary people of Canada got to do with the price of bread?

Perhaps you could offer something constructive to the discussions rather than continually asking questions?

Yupp! 🙂

No, I really do mean "All math don't describe reality".

As in; every mathematical formula or model don't have a relation / don't describe, reality.

Don't / doesn't... Do not / Does not... is it a grammatical error by me?

The correct form is "doesn't", TNT. 🙂

There is currently no single mathematical model capable of describing the reality of our universe. The cosmos lies far beyond our present embryonic ability to understand it.

Astrophysicists draw up mathematical models that try to align with their observations of the universe, e.g., the observation that it is expanding at an accelerating rate.

The power of mathematics is in its potential to predict more about the nature of the universe than we can currently observe and hence lead to new scientific investigations and a deeper understanding.

Anyone who thinks that any of our current mathematical models represent the reality of the universe is severely deluded.

Aha - must have missed that particular class... ;-)

...checking a bit...

  • “Do” is used for plural subjects like “you,” “we,” “they,” “these,” “those,” or “John and I,” as well as with “I.”
    Example: They do not like snakes.
  • “Does” is used for singular subjects like “he,” “she,” “it,” “this,” “that,” or “John.”
    Example: John does not like snakes
All math don't describe reality.

... all that Math .... all these Math... ?

"All Math..." would be plural - right?

"All Math..." would be plural - right?

Mathematic, maths and math are uncountable nouns (we cannot count "maths", but we can count "maths books") which we usually treat as singular and which are used with a singular verb - like "does" or "is".

We don't say math "are" my best subject, we say math "is" my best subject.

I don't think "All math..." makes sense since math is not countable, but I'd use "doesn't" with it. However "All math books..." would make perfect sense and would be used with "don't".

Yes, I pieced the above together courtesy of an internet search! You may be able to google different interpretations - it's a jungle out there! 😀

Time for another excruciatingly funny Mathematical Joke:

John and Bill, math teachers, have lunch at a restaurant discussing the level of mathematical knowledge of the general population. John is of the opinion that the level of these knowledge is very, very low and that something needs to be done in this sense, while Bill considers that the level is absolute satisfactory, that the common man knows even more mathematics than he needs.
At one point, John goes to the bathroom and Bill thinks it's time to take advantage of this situation. So he calls the waitress and says:
"Miss, I'll give you a hundred bucks if you help me in one little problem".
"Sure, say it".
"When my friend comes back from the bathroom, I'll ask you one question. It's going to sound weird, but don't worry, just answer 'x to the 3rd power divided by 3'. Do you think you can help me?"
"Sure, no problem".
He gives her a hundred and the girl leaves satisfied. John returns from the bathroom and Bill tells him:
"Look, to prove you I am right, I'll give you an example. Let's take an ordinary person, for example the waitress who serves us, and let's ask how much is the integral of x square. I bet you two hundred bucks that she knows the answer".
"Get out of here, be serious, let's try to give her some easier arithmetic calculations, how can she know what's the integral of x square? ..."
"I say she knows. Do we bet on two hundreds?"
"It's done, I'm telling you from now on that I won the bet," John says.
Bill calls the waitress and says:
"Miss, my friend and I had a little discussion and you would be very helpful if you could answer a question. Can you tell us how much is the integral of x square?"
"x at 3rd power divided by 3", the girl answers very calmly.
John looks at the waitress in amazement, while Bill looks at him triumphant.
After a few seconds the girl continues:
"Plus a constant."

Mersenne forum ( a place interested in calculating very large Prime Numbers) is the only place I know where even Jokes are Peer-reviewed! 😀

The nature of infinity is some infinities are bigger than others. The Integers (1,2,3,4...) have a Cardinality of N(()) IIRC. The Reals which include Pi and e, have a higher order of infinity N(1), I think.

This is not my field, so don't ask me more. https://en.wikipedia.org/wiki/Continuum_hypothesis

Tricky stuff IMO.

What we find on investigation is that our concepts including Conservation Laws of Energy, Mass and angular momentum are very badly defined. Nobody is quite sure what ANYTHING really is! It's a quagmire.

https://www.quantamagazine.org/mass...t-ambiguous-by-einstein-get-defined-20220713/

The key is to be clear if we are looking at a system from the outside or the inside IMO. We are definitely on the inside of the Universe so must be extremely careful what we assume about experiments on what appears to be the surface of a 4D spacetime manifold.

I continue to be interested in the number system known as Octonions, in which Associativity breaks. It is hard to find a Physical example of non-associativity, but I am pondering it. I think it breaks the cross-product of horrible Vectors.


Cohl Furey has been considering a multiplication of Reals, Complex, Quaternions and Octonions, the 4 division algebras, and has derived a reasonable theory of Quark and Electro-weak Symmetries. The three generations of matter is unresolved, but it can't be too hard can it?


I like what I am seeing thus far.
