I really like Linear Algebra Done Right by Axler

The best strategy for this in my opinion is to always ask “what’s the picture” (as in visualization)? I can’t remember the mechanical rules for say Newton’s method, but I have the picture of what Newton’s method does in my head. From that, I can quickly work out the algorithm.

I learned the spectral theorem with a couple applications in the first semester of my electrical engineering graduate studies. First year graduate material is commonly called basics in my experience. Compared to the state of the art, it is. Compared to what an undergraduate freshman knows, not so much.

I believe they do this because the real target audience is other professors. The author wants those professors to use their book for their own courses, and a bunch of problems with no answeres saves a lot of time. There seem to be very few books written with the autodidact in mind. Sometimes you can find the solutions manual via eBay or torrent though.

An appeal to ignorance requires to me make an assertion. Saying something is _possible_ is not an assertion.

I concur however, that if one has a genuine concern for plant suffering then only ethical course of action is suicide.

All that demonstrates is that mammals can recognize each other’s suffering. It’s entirely possible that when a plant is killed, there is also suffering, but it’s so foreign to us we can’t recognize it.
