I tossed my calculus and linear algebra texts long ago but still have abstract algebra, combinatorics, and graph theory texts, which I found more interesting and somewhat more useful. I've reopened them a few times and my experience was similar to yours, though maybe not quite as depressing.





I'm teaching a friend's highschool age kid software engineering. This week we're going to study sorting: bubble, binary insertion, quick and merge. Bubble is trivial, but I'm dreading the others. What's worse, he's very bright and thinks I know what I'm talking about.

I'd say that merge is also rather trivial, but after that I'm very happy not to be in your shoes.






Yep.

Loved the link!! Where was YouTube when I was learning the QuickSort? Oh right ARPANET didn't have YouTube.





Playing cards are useful tool. Shuffle them, deal them out and then demonstrate one of the algorithms to physically sort. Get student to have a go.
Then show the algorithm's pseudocode and show how it links to the physical process of sorting the cards. Allow only one card to be moved at a time or you will end up combining statements into one, you'll need to designate a space on the table as register/memory location.
If you want to demonstrate why a computer needs these algorithms, whereas a human does not, turn the cards face down and allow only two card faces to be seen at any one time while applying the algorithm.
Practice beforehand





You're so screwed

Understatement!

One of my Engineering profs told us,
"After you graduate you will forget half of what you learned. Also, you will only use half of what you learned. The trick is to forget the correct half."

Just curious, why would you hold onto those books for so long?

How long have you held onto your wife?





Have you told your wife that you are comparing her to a bunch of old books?

Well, it's better'n a bunch of old bags, innit?

I did (helping out the son of a friend). And there are very, very few that are better than mine back then.

Yes. I have had the need a couple of times, due to things I was working on. I have not and won't reread the whole book, for sure I will probably never touch again some chapters. But it doesn't mean that the whole book is not worth to keep.

I had edited my message, but since you were that fast answering... I post it here:

Those books are like old, old friends. I had some of the best and worst times with those books.

This is something that I've been doing in my retirement. What I do is come up with a personal set of notes for any subject, with the complete derivation & proofs of applicability. I have substantially finished notes for Algebra (i.e., regular Algebra, not Abstract Algebra), Linear Algebra, Trigonometry, Analytic Geometry, Geometric Optics & Special Relativity. I happen to be in the middle of Calculus, and to give an idea of how thorough my notes are, I've derived every integral formula that one would find on the inside cover of a Calculus book and have even gone through the epsilondelta proofs needed to be able to prove that a certain function is continuous (a necessary condition for calculus to work).
I delved into Linear Algebra quite deep, proving that all the stuff that was simply lectured as fact in the typical "Differential Equations & Linear Algebra" course for nonmathematicians, like why the determinant of the product of a pair of matrices is the product of the determinants of those matrices (something that simply wowed me when I learned it) and similarly about rank (and how to determine it) and finally about null space and how it really ties into the eigenvalue problem, and also why & when a matrix can even be diagonalized via eigenvalues, and finally why the mechanical vibration problem works having a pair of matrices instead of just a single one. I studied Mechanical Engineering, and so there is plenty of stuff to review (i.e., at least the advanced "basic physics" engineering science material), etc.
For regular Algebra I was able to grok how Lagrangian resolvents can be used to get formulae for the cubic & quartic polynomials  including an extraordinarily geeky delving into those formulae. I even derived the method of partial fractions, which is used in Calculus, and why it works.
Last but not least, I've even examined isohedra (i.e., all the different shapes that can used in Dungeons & Dragons). There are still a few classes of shapes I need to go through.





But do you know the average laden velocity of a European swallow? Sound like you have been having fun!
