What do you like about this subject?

Mathematics enables us to apply abstract principals to provide solutions to everyday problems as well as extend our understanding of the Universe. Being able to provide a mathematical solution that bridges the gap between intuition and a solid appication is very fulfilling.

What do you still hope to achieve/learn in this field?

I hope to acquire more thorough understanding of the many aspects of math and their relation to real world problems. I enjoy helping people understand the often deep results of mathematics and how they can reveal underlying relationships.

Something interesting about this subject that others may not know:

Integrating functions of real numbers (basically summing the values of a process to reveal its behaviour), uses several techniques taught in calculus. For complex numbers, combining real and imaginary numbers (square root of -1), the approach relies on powerful, elegant theorems to transform the function and its domain to obtain the value of the integral in a completely different way.

Something controversial or provocative about this subject

Humor: The famous mathematician Erdos once quipped that a mathematician is a machine that turns coffe into theorems.

2016-11-21 Functional analysis:

We can take as an example of an infinite Hilbert space the space of complex functions f of a complex argument, z, which are square integrable (integral of square < ∞) and which has an inner product

2016-08-26 Composition of Functions:

I think your conceptual difficulties arise from trying to define the function g in terms of x instead of h. Let me try to clarify.    If I have a function, say g, it operates on an argument, which I'll

2016-08-25 Composition of Functions:

Defining h(x) = 1+x is a good start.     Now we want to end up with f(x) = 1/(x+1) which would be f(x) = 1/h(x). This would define the function g by g⚬h = 1/h.    When I work with compositions of

2016-07-27 Eigen Values:

I agree that eigenvalues and eigenvectors can be a bit of a mystery.    Iíve come to think of eigenvectors as representing the basic structure of a linear transformation (LT). A basic theorem of linear

2016-06-13 Solve this equation for x:

Hi John,    I don't think this expression has a closed form formula for x. The best you can hope for is a series or numerical solution to get an approximation. I know this isn't what you are after but
