Infinite Universe?
That's the problem with infinities, you get swamped with paradoxes. Fortunately, our universe has a temporal cutoff, otherwise known as the finite age of the observable universe, which spares us such

Where Did Our Numbers Come From?
You can imagine how hard it must have been to do business in ancient times, before numbers were invented. To show a quantity, tradesmen used their fingers or bags of stones.

A Methodology for Deriving Probabilistic Correctness from Recognizers
"... In several tasks from different fields, we are encountering sparse events. In order to provide with probabilities for such events, researchers commonly perform a maximum likelihood (ML)
estimation. However, it is well-known that the ML estimator... | {"url":"http://citeseerx.ist.psu.edu/showciting?cid=8008753","timestamp":"2014-04-16T09:07:36Z","content_type":null,"content_length":"12900","record_id":"<urn:uuid:303c3670-af7b-4c95-adc7-2a6df1d75724>","cc-path":"CC-MAIN-2014-15/segments/1397609521558.37/warc/CC-MAIN-20140416005201-00054-ip-10-147-4-33.ec2.internal.wa... |

LaTeX bug?
Looks to me that you found a bug in MathJax!
Spaces are not supposed to be significant in Latex.
They are only required to separate operators from operands if necessary, like \sin x, which is different from \sinx (which is an error:##\sinx##).
I googled for confirmation, but could not quickly find it.
