ok agreed, but obtaining success killing yourself has a tiny
little element of contradiction in it. normally success is

if one should consider, predicting weather, building a computer
a 'practical application' then the science enabling us to do this
has something 'to do' behind the scenes.

if consequences do not follow, ever, do you think that the
science will be alive&kicking, gaining success, despite of it's
lack of consequences ?

yup, depending on application, one or the other science will do.
Iv'e heard that the finns have been messing with gravity, above
a superconducting spinning disc. I wonder what newton&boys

sure, aren't we all blissfully unaware of something

turning left might be right,spinning gets us right back, what
is left is the headache, right?
