Hi,

It's because of Science of Diskworld 1 & 2.

A little bit more detailed:
It's all about the second law of thermodynamics and somehow there appears to be another still unformulated law in the universe that says something like:
"There are things that are meant to come together because they fit." (+)

Like Darwin hitching a ride on the Beagle.

Or:

1.) What happened around me and a few friends here is that one of us fiddled together a little gadget that seems to break the second law of thermodynamics. It clearly puts Lord Kelvins statements in the 'good try, close, - but no cigar' basket. Not so with Rudolph Clausius' and his maths which were formulated later. Well, at least the way the few of us understand and use the formulas.

The formulas stand like a rock as far as we can tell, but our discussions are heated.

Further, I'm from Austria, so my first language is German and all the original variations of the 'zweiter Hauptsatz der Wärmelehre" I read stand up solidly, whereas any english translation I came across seem to be lacking in
quality and understanding.

2.) At the same time I happened to read TP's "Science of DW II - the Globe" - only half way through - and that's the part on the 2nd law.

1+2 = just fitting too nicely with my "second unseen law of the universe" - (+) to let it go by, so 'google is your friend' and I ended up finding this
thread:

... close, but no cigar. As any of the posts state clearly that the science TP talks about twists already their thoughts into 3D pretzels and I really think it would be very inconsiderate of me/us to plunge into it with our story like Obelix into a swimming pool. It would take the fun out for many, achieving nothing.

No-fun paths are no-good paths so I keep on googlin' and considering that TP-readers and TP himself show to like looking at things from fresh angles, a bit deeper and never leave the fun part out startng out here appears promising.

The bone dry scientific approach to bring about understanding of the 2nd law clearly didn't work very well for about 150 years. I have high hopes on the TP-way, I just can't find it ...

Thank you for your time,
