An economist regarding mathematical research as a product and mathematicians as producers would note that it has a distinctive feature: one's customers are basically the same as one's competitors.
Seeing an astronomer using a telescope to observe a galaxy, no-one will confuse the telescope with the galaxy. Mathematics differs from science in that there is no clear distinction between the tools and the objects of study.
-- David Aldous
I think that it is a relatively good approximation to truth [] that mathematical ideas originate in empirics. [A]s a mathematical discipline travels far from its empirical source it becomes more and more purely aestheticizing, [t]here is a grave danger that the subject will develop along the line of least resistance, that the stream, so far from its source, will separate into a multitude of insignificant branches, and that the discipline will become a disorganized mass of details and complexities. [W]henever this stage is reached, the only remedy seems to me to be the rejuvenating return to the source: the re-injection of more or less directly empirical ideas.

In recent decades, many investigators published a great number of mathematical works. Whereas the classics of mathematics regarded the science of mathematics as an objective reflection of reality, many of the new investigators do not share this opinion.

The object of mathematical rigour is to sanction and legitimize the conquests of intuition, and there was never any other object for it.

I've seen things you people wouldn't believe. Attack ships on fire off the shoulder of Orion. I watched C-beams glitter in the dark near the Tannhauser Gate. All those moments will be lost in time, like tears in rain. Time to die.

There are worlds out there where the sky is burning, where the sea's asleep and the rivers dream, people made of smoke and cities made of song. Somewhere there's danger, somewhere there's injustice and somewhere else the tea is getting cold. Come on, Ace, we've got work to do.
-- Dr Who
..Statistical users will be better off if they take note of a two-stage test-of-significance as follows:
Step 1: Is the difference practically significant? If the answer is NO, don't bother with the next step.
Step 2: Is the difference statistically significant?
-- From the book: Sense and Nonsense of Statistical Inference
It's difficult to get a man to understand something when his salary depends on his not understanding it.
