Some Thoughts Thoughts of P | Comment 39 of 45 |
So, then, having finally gotten that through ... What is it I think of P?
    Well, when I think of infinitesimals, immediately I think of delta ... as in dy/dx ... or inf. from the Latin infimum, accepted maths convention also.
However, the P should be acceptable, too. Simply have it clear at the start and remain with the Roman so as to avoid confusion with the Greek.
