Definition of research activity: If we knew what it was we were doing, it would not be called research,
would it? (Albert Einstein)

Was vernunftig ist, das ist wirklich, während was wirklich ist, das ist vernunftig. (Grundlinien der Philosophie des Rechts, Vorrede §. 17)
What is rational, it is real: what is real, it is rational. Are real numbers rational numbers?

about the concept of information:

Weird Properties of Information

Can be used without being consumed

Production cost unaffected by number of consumers

Exists independent of space (cake vs. recipe)

Cannot be repossessed

Extremely sensitive to time (betting tip)

Production costs heavily front-loaded

Suppliers and consumers collaborate

Curious sorce code

I found this simple(?) yet hard to read source code in C.
If you want to have fun, cut & paste it to your computer, compile and run it.
But, before running it, will you try to figure out what output you will obtain?
(or look at the output of the code)

#include <stdio.h>

main(t,_,a)
char *a;
{return!0<t?t<3?main(-79,-13,a+main(-87,1-_,
main(-86, 0, a+1 )+a)):1,t<_?main(t+1, _, a ):3,main ( -94, -27+t, a
)&&t == 2 ?_<13 ?main ( 2, _+1, "%s %d %d\n" ):9:16:t<0?t<-72?main(_,
t,"@n'+,#'/*{}w+/w#cdnr/+,{}r/*de}+,/*{*+,/w{%+,/w#q#n+,/#{l,+,/n{n+\

And finally ... another puzzle

The table, related to a Latin sentence, reads correctly by rows (i.e. from top-left to bottom-right), by columns, by backword rows (i.e. from bottom-right to top-left) and by backword columns (i.e. from the bottom-right to top-left).
