Let's look at the second number, epsilon, which is roughly .007.
Hilbert developed a method for the study of consistency problems, called the epsilon substitution method, to deal with the quantifiers.
The EKG may show inverted t waves in right sided leads and the so-called epsilon waves.
I've been listening to a few odd bits and pieces of music these last few days (wanted to try and get the word epsilon into the last 3 words before the bracket, but couldn't ... conversation today re: possible other name for one of the rooms in MVB (Merchant Venturer's building, home of CS ppl ehre in Bristol) which is called 0.01, which spawned that idea floating around in my head).
If you carry two copies of a variant called epsilon 4, then your risk of succumbing to Alzheimer's disease is greatly increased.
The pressure dependence of the melting point is indeed the key to the solution - it turns the arbitrarily small "epsilon" temperature difference into a finite delta T, the difference between the freezing point of water under the pressure of the weight and the melting point of ice after the weight is removed.
For any finite "epsilon", the infrared problems are absent.
The measurable results are independent of "epsilon".
You should ask what is the cross section to create two photons plus an arbitrary number of photons whose energy is so small, below "epsilon", that you can't really detect them.
Once you admit that you can't measure the photons whose energy is below "epsilon", you eliminate the infrared divergences from the loop diagrams, and the part that diverges for
