Mathematics is only a hobby - although I have done undergrad courses in the 70s. But part of my job was doing statistics and this kept me near my favourite subject "linear algebra" (programmed factor-analysis and a matrix-orientated calculator MatMate). Around 2002 I came in contact with the internet community in math newsgroups and could improve my Collatz discussion. Next subject was the Bernoulli numbers, then integer matrices and since 2006 the problem of iterated exponentiation aka tetration. Serving half-time jobs in teaching here at the university I found time to fiddle with that subjects in depth - and found love with the exploratory approach and impulse of the 18'th century numbertheory, namely L. Euler, "the master of us all"... Due to lack of formal education I've to do my "research" widely on my own - but that's what I just like: to find structure, pattern, laws from the ground.

comment What's the difference between the universe and the cosmos?
"...which was the first state of the universe" - well, we don't know this - it is just an extrapolation, done by a cosmic ("ordered") mind ;-)

comment Garbage/stuff words
While you are ... uhhm ... correct - using fillers conciously can sometimes introduce irony/sarcasm/scepticism and other semantical ...ehm... coloring. (just joking ;-) )

comment How serious an insult is “wanker” in British English? [NSFW]
whew... Good I didn't understood much of the conversation; just listened to the strange sound of the cockney which is nearly uncomprehensible for me - and only heard this word clearly spoken just after reading the question here...

comment How serious an insult is “wanker” in British English? [NSFW]
I followed the question english.stackexchange.com/questions/20563 concerning cockney-english and watched the linked video. Accidently, the very last comment on a nice taxidriver was a nice example of the use of just... "wanker!" ;-)

@Jimi: "German", sorry. (Would "germane" mean something meaningful here, btw?)

comment How to use the expression “lo and behold”
Concerning the german "be-halten": well, I'd say one should relate it to the german "inne-halten", and here "halt' inne/halt' ein". "be-halten" is either possessive (I'm owning it/I'm keeping it) or means to remember some thing (keep it in memory/mind).
