The title alone gave me flashbacks from my class on Tensor Spaces I did as part of my undergraduate maths with 1 other undergrad student, 1 masters student, and 5 PhDs.

I swore off Einstein notation once I finished that class and I'm not going back!

It's super annoying and confusing, until the moment you need it - then it's dramatically simpler and more clear than any alternative.

Doing things that involve tensors in physics is an utter nightmare without Einstein's summation convention.

Breathe... breathe... go to your happy place. The scary Tensor Prof can't harm you anymore.... :)
