The fact that in maths the right of the first has a concrete meaning. Because
finding a necessary proof for some 'sentence' is important because prior to that
nobody had found a proof. So far about maths and its proofs. For some proofs you
can still get a million of dollars...

But now to other sciences and applied departments.

You are right. You were first but still not for a question of high importance or
it must be a special difficulty caused by some principal obstacle you could
overcome while working on the 10-piece task. But being first as such can't
always have the same importance as in maths. It  is said that in CC for the last
two decades not very many innovations had been found but that the hardware was
the most important factor. So, we can't applaude the one who mastered the new
hardware as first with the same enthusiasm as in maths. Admiration is not a
juridical term. In maths finding proofs has an internal logic and importance. In
other sciences often the first who found revolutionary applications of a new
invention is more admired than the one who made the discovery itself.
Electricity as phenomenon and Edison as inventor of the light bulb is a good
example. Of course sometimes there might me a debate about what is important.

Must I state that I'm not teaching you personally at all but that I wanted to
post this comment for the general debate. :)
