docs: food for thought

[xames3]

below are some ideas that could be shared on the website as a good teaching material or as a medium for sharing noteworthy resources to better help people (or myself), learn and understand some concepts:

• arrays (higher rank tensors) with some relevant examples
• why do we need non-linearities?
• nasa open science experiences
• normal distribution (or other distributions, maybe?)
• [docs] good youtube resources for some topics? #68
• a series of explainers (aptly named, explained)
• git 101 (in explained)
• docs: docker 101 #49 (in explained)

Note. If any of the above ideas goes into production, it should be linked with proper issue and PR

• workflow docs is in the works for a while and I've made significant progress on that. the only thing that is remaining is ImgBot integration
