Thus what fruits mathematics brings: only theory that is equivalent with thoughts moreover the theory without application(practice) is only thoughts about sex or in the better case is a simple masturbation)

Fruits of Physics:
All that you see around you is due to physics(nowadays medicine or chemistry or army, computers, cars, buses, airplanes…)
And don’t tell me that Electricity was discovered by mathematicians!
Now, can you imagine one day without electricity?
Moreover, now the physicist work in order to obtain quantum computers, By the way the simple word of quantum it is so far for all mathematicians, also theory of groups, differential equations (in fact all mathematical analysis belong to theoretical physics!!!) all this things was started from physics and are developed also by physics!!!

Conclusion:
1 Each physicist from the start is a greatest philosopher (see history of philosophy)
2 A theoretical physicist can solve any problem of mathematicians but not inverse(mathematicians cannot solve even a simple problem of physics)that’s why we have many mathematicians and a few of physicists(in order to get insight in physics you must be very wise because that is not easy at all, and it is not given for all ordinary people(I mean mathematicians)). It follows that a real physicist are a genius.
3 Physics is more than sex.
“Physics is like sex. Sure, it may give some practical results, but that’s not why we do it.” – R. Feynman

Seems likely I was snookered by the old tendency of quotations to fall towards more and more famous attributions, because the process doesn’t usually work the other way.
