Reddit mentions of An Introduction To Quantum Field Theory, Student Economy Edition (Frontiers in Physics)

>Are particles not spatially extended?

In quantum field theory particles come from acting an operator, which fundamentally are solutions to some wave equation, on the vacuum. This his how physics treats matter in QFT, not as a closed system. See Peskin and Schroeder.

>>Are you every going to address my other comment about how you're utterly incorrect in your understanding of how to quantize geometry in Loop Quantum Gravity?

>Has LQG been solved using the apporach we have been attempting?

You're not attempting anything. You're throwing numbers together and massaging them to get something reasonable looking. It's numerology, not science.

>Space is granular. Space is made of woven loops of the planck length diameter. Quantized granular space yields the exact mass of both protons and black holes, answering the fundamental question of the source of mass in the Universe.

This is still not a justification for what you're doing. LQG quantized geometry in a specific way. It involves quantizing the vector product of the vertices of different geometries by invoking the LQG equivalent of the canonical commutation relations in quantum mechanics, not whatever you think you are doing. See Carlo Rovell's book, which I linked you to in my other comment.

I will echo the other reply here. The math of QFT is very esoteric and not easy to understand or use. The best path there is a solid grounding in graduate level physics -- classical field theory and quantum mechanics in particular. The Standard Model is even more complex because it relies heavily on gauge theory. As for a text explicitly on QFT, Peskin and Schroeder is a commonly used one which is oriented towards particle physics applications. You can use the preview to get an idea of what you're getting into. If it looks like gobbledygook then more prerequisite learning is necessary.
