Was this meant to be serious? Checking for any subtle structural changes

to a deeper understanding of the phenomena.
We still wait for a deeper understanding of the phenomena,
since 1986, right ? And this, after thousands of characterizations.
You really think that MgB2 will
You really think that MgB2 will give more ? Maybe... just routine to do so.
Armel, it was you who asked if boron was possible with neutrons, and when
you are told that it is, you say that anyway it is borin' (excuse the pun :-)
Well, let me predict the future of the coming paper : high
If you know how to guarantee high citation levels, go to it :-)

reactor for research in the world ;-). Knowing how

Is it really
worth trying to belittle what should turn out to be excellent science?
A serendipity case. Once more. Where is excellency exactlly,
according to you ? I repeat that excellency would be to produce
a theory which would have allowed to predict the MgB2
superconductor properties.

Dang... I'm glad that we didn't have to wait for excellent science to
theoretically predict penicillin for us.
Absolutely ! The whole humanity is lucky that things to be
found, whatever, are discovered times to times. Fire, the wheel,
who remember the inventors ?
But our era is lacking of

Yes, neutron absorption by boron is a potential problem, however use of
