No because no "run away" effect. "inverted" mass means that the mass goes on the other side... gravity works the same there.

Or we could shift to an other side of the universe by "inverting" the mass of the ship where the speed of light is much higher[1].
Cosmology is so cool... too bad we do not have time for that: we cannot even cure the common cold!

Unfortunately, no... But the french used by Grothendieck is
surprisingly simple : it should not be too much of a challenge
with Google translate, a couple of months and some courage.

"Why Does Julia Work So Well?
There is an obvious reason to choose Julia:
it's faster than other scripting languages, allowing
you to have the rapid development of Python/MATLAB/R
while producing code that is as fast as C/Fortran"

> he would have a hard time convincing other scientists in its validity, because of his... other convictions.
atemerev apparently does not understand what science is ... but keep posting your personal convictions.

So much truth in here... Specially for the "just funded" startups : they loose their souls fast when the investors start to get impatient. It's a trap in so many cases.

It's a great idea and I think it's much bigger than maths.
If you do not already know about it, searching around what
a "Dynabook" is cannot be a waste of time.

Exactly.
/speculation
There is a point where one starts to see "behind" the symbols. It's a strange sensation, as if one could understand the ideas in a non-verbal way. The symbols become optional. Intimidation crawls back before curiosity at this point.
An amazing book on the subject is:
"Hadamard - The psychology of invention in the mathematical field"
