Apparently there is an actual experiment on six-year-olds taking place [1,2]: "Experiment. Consider ten children of ages between six and ten and consider ten high-school teachers of physics and mathematics. The high-school teachers of physics and mathematics will have all the time they require to refresh their quantum mechanics background, and also to update it with regard to recent developments in quantum information. The children on the other hand will have quantum theory explained in terms of the graphical formalism. Both teams will be given a certain set of questions, for the children…

From [0] 2018: "In [1] we present an entirely diagrammatic presentation of quantum the-ory with applications in quantum foundations and quantum information.This was the result of many years of work by many, and started of as acategory-theoretic axiomatisation motivated by computer science as well asaxiomatic physics. However, I have always felt that the diagrammatic pre-sentation is of great use in its own right, be it to bridge disciplines, makequantum theory more easy to grasp, or, for educational purposes, in [2] wemade the bolt claim that using diagrams high-school kids could even…

I believe Roger Penrose draws all his own illustrations. For copius excellent examples, see his book Road to Reality. Here is one example: https://phys.org/news/2018-03-math-bridges-holography-twisto... https://theportal.wiki/images/1/11/Penrose-Rindler-Clifford-... He also comes from the pre-ppt age of presenting with handwritten acetate transparencies - and still does afaik. Many of his slides have been captured for the infowebs. http://cgpg.gravity.psu.edu/online/Html/Seminars/Fall1998/Pe... http://cgpg.gravity.psu.edu/online/Html/Seminars/Fall1998/Pe... Some of his original papers from…

Quantum computing is all about the tensor product. This is, roughly, how "and" works in the quantum world. Learning about tensor products by calculating with matrices is dizzyingly complicated [1]. But there's another way, using string diagrams [2]. [1] https://en.wikipedia.org/wiki/Kronecker_product [2] https://arxiv.org/abs/0908.1787

I think it is generally useful for people to have a picture in their head about whats going on as work quite frequently gets lead by instinct and educated guesswork which can be made rigorous once you've decided its worth the time to do so. That said I really don't understand the appeal of Bohmian mechanics. The explicit non-locality puts me off it. On a more positive note the stuff about category theory is very interesting and I think has a lot to offer physics in general and quantum mechanics in particular. I found a couple of papers by Bob Coecke made a good introduction to the use of…
