Science is a phenomenal exploration of nature. We hope to hone our skills of problem solving by exposing ourselves to multiple contexts. In doing so, it can sometimes be challenging to see the connection between topics. I yearn to understand ๐™๐™ค๐™ฌ these aspects of physics, unite together. To accomplish this, I'll cover all of my old textbooks through QFT; the convergence point of the many modern scientists! These posts are very much in a "๐˜ฏ๐˜ฐ๐˜ต๐˜ฆ๐˜ด ๐˜ต๐˜ฐ ๐˜ด๐˜ฆ๐˜ญ๐˜ง" style. ๐™ˆ๐™ฎ ๐™๐™ค๐™ฅ๐™š is that by sharing this exploration, I can help others navigate the beautiful world of mathematics & physics through problems and examples, connecting the mathematical tools to their physical ramifications.

I understood your reasoning for taking the positive value of the absolute value. But how am I gonna explain it to the examiner in exam? Will I have to mention the reasoning or he can figure it out on his/her own?
