I like quaternions and a certain branch of mathematics 'called geometric 
algebra'.

One of the pioneers of the use of this concept in physics was David 
Heestenes.

But for decades his works was regarded as very exotic stuff from the far 
end of science.

In common books about general relativity, for instance, a different type 
of math is tought. This math is very strange in my oppinion.

For instance I dislike the use of superscripts for indices. (That space 
should be reserved for exponents).

This strange habit makes it very difficult to say, if x² means x*x or a 
second x variable with the index two.

Another strange habit is something like y=y(x).

This sounds familliar, but one y is an dependent variable and the other 
y (in y(x) ) is the name of a function.

These are two different types of mathematical objects, hence cannot 
possibly be equal. Therefore the one y is not equal to the other y, 
while indistinguishable from the apperance.

It is therefore required, to distiguish different types of objects by 
certain signs, like e.g. a bold font or little arrows over vectors.

Another issue is the missing separation between math and physics.

I would like math to provide mathematical tools and physics to connect 
them to the real world.

In other words: math books for physicists should not discuss physical 
questions, while physics books should not attempt to create new forms of 
math.
