Did you know that mathematics is just a useful fiction?

There are objections.  But this gets back to Pythagoras' cult, Plato's Academy and other crap.  If arithmetic is a useful fiction (it exists because humans and other sentients invented it and found it useful) ... what of other cultural constructs, such as religion ;-)

Create your own Universe

If you read the above publication from Zeeya Merali, which I read in 2006 in Popular Mechanics, you will actually be a witness to how creative theoretical scientists are.

One will think that they started off with almost nothing, got a space vacuum in a space vacuum, bubbles of nothing popped out, a cosmic string was caught, is was placed in this space bubble, and a whole new universe came into existance by scientists waiting and watching the bubble grow infinitely large from the inside, but from the outside it remained infinitely minute.

One eventually then realize that it was never done in any lab, but it was mathematical equations manipulated by theoretical physicists all over the globe, to speculate on how it should be done, but these scientists need billions of dollars to build larger accelerators.

then again on the other-hand, if it was not for mathematical calculations, we would not have had Transistors.
Or is that also a concoction in the story of science.

Well, at least Newton used maths and it proved to be correct.
Oh, wait.
He used maths to calculate the observation, not create maths to postulate on theories.

Popular mechanics edition
Oh, I found it here.
It is a pity that not the whole article is available, but just read this nail biting scientific devour done by Sakai, Linde, Eduardo Guendelman, Alan Guth, Ed Farhi, Willy Fischler, and Jacov Portnoy.

Now, they might be great mathe-maticians, but they are even greater Mathe-magicians.

Then people say I feed everyone BS!

Sorry, only one unconfirmed magnetic monopole observation in history.  So building your own universe will have to wait.

Observations (to the limits of available equipment, as an extension of our senses) are true in themselves.  Theories based on observations fall like leaves from trees in Autumn. 

And, forgive me if I misunderstand this, but didn't Newton use maths to explain the observations rather than the reverse?  I think you have it backwards.

The concept of mathematics varies between cultures, which to me shows that there is at the very least no inherently "true, one way to do" math. It is simply a language... one that is extremely versatile and useful, but a language non-the-less and thus one that is influenced by the culture practicing it. There are concepts that stand true amongst essentially all cultures, but the same can be said of language... nouns, verbs, adjectives exist in essentially all modern languages but that doesn't make these concepts "true" any more than 1+1 = 2 "true".

In what way is 1+1=2 not logically true? 

[Shiranu]

It is logically true in our system, but that is not a statement of "realness". In mathematical systems that allow for the division of zero, you can have equations such as 1+1=1 and it makes logical sense as well.

Again, mathematics is just a form of language... there is no entity in the universe that is "1", only abstract conceptualization of "1".

A good example is "zero"... was "zero" a true number before the Mesoamericans or Indians invented it? We would say yes, but to anyone who existed before the concept of zero was conceived... they would say no. Is either side right or wrong? It all is subjective to what culture you were born into, what "language" you speak, so I would argue no.

I have come across this argument before.  There is a reason why, in practical terms, there is "1" (a singular quantity).  And another "1" makes "2".  I actually doubt that this would be untrue in any universe or rational system of counting.

In theoretical maths, I suppose there are ways for this not to be true, because you can set up any axioms you choose.  5 +7 = 10 in base 12.  Does that make 1+1=20 in base 1? 

I live in base 10.

Yes, in more abstract math, you can pretty much do anything you want, provided you are self-consistent.  Pythagoras was a demi-god, but he didn't know zero etc.  Euclid isn't a description of real space, for example, but it was thought to be so for 2000+ years.  This is why math isn't equivalent to reality.  It is the most abstract of languages, and is very useful as such, particularly in science and technology.  Interpolation is fairly reliable, but extrapolation less so.

Why is there no 2 in base 2, no 3 in base 3, etc.?

;-P

I suppose, but imho mathematics is a language meant to describe real-world interactions.  1 + 1 describes a set of one combining with another set of one to create a set of two, like a person with one cake acquiring another cake.  Mathematics is just the abstraction of that real-world scenario. 

Of course, not all math maps to reality - imaginary numbers and so forth exist because the logic that math operates on allows for i^2=-1 as well as 1+1=2.

[Cavebear]

Why is there no 2 in base 2, no 3 in base 3, etc.?

;-P

Because "3" in base 3 is "10".  Counting numbers in base 3 are 0, 1, 2, 10.

Study Claims Gifted Math Classes Promote 'Academic Apartheid'

A math education professor is arguing that gifted math classes cause “academic apartheid” among students, claiming that the practice is rooted in “capitalist exploitations and settler colonialism.”
