Best Explanations of Renormalization in Quantum Field Theory

image credit Renormalization in Quantum Field Theory is a complex subject. I tried to collect the accessible explanations. I hope this helps. John Preskill in “We are all Wilsonians now” John Baez on renormalization Sean Carroll’s explanation Renormalization for philosophers … Continue reading

On the concept of scalar field

In physics (cosmology) “…scalar fields—fields that look the same no matter how you view them, but can contain energy or pressure. Their high level of symmetry suggests that one would be most likely to find them in the earliest moments … Continue reading
