Continuum mechanics notes now in book format at amazon.com

My notes from the 2012 UofT session of phy454, Continuum mechanics (aka fluid mechanics), are now available in book form on amazon.com for $10 (black and white, softcover, 6×9″ format, 358 pages), as well as in PDF and latex formats as before.

I took that course as a non-degree student.  It was taught by Prof. Kausik S. Das, and had the official course description:

The theory of continuous matter, including solid and fluid mechanics. Topics include the continuum approximation, dimensional analysis, stress, strain, the Euler and Navier-Stokes equations, vorticity, waves, instabilities, convection and turbulence.

It was really only about fluid dynamics. Anything related to solids was really just to introduce the stress and strain tensors as lead up to expressing the Navier-Stokes equation. There was nothing in this course about beam deformation, Euler stability, or similar topics that one might have expected from the course description.

If you download the free PDF, compile the latex version, or buy a paper copy and feel undercharged, feel free to send some bitcoin my way.

Marks are in for Winter 2016

I started my formal re-education program back in 2010 after 20 years out of school. The first few courses were particularly tough after such a long break from school (and exam based courses still are), but I’m getting the hang of playing that game again. Here’s my score so far:

This last grad course is the only one of which they gave (informally through email) a non-letter grade (97). That one happened to be very well suited to me, and did not have anything based on exams nor on presentations (just assignments). They were demanding assignments (and fun), so I had to work really hard for that 97.

As a returning student I really suck at classes that have marks that are highly biased towards exams. My days of showing up late for class, sleeping through big chunks of the parts that I did get their in time for, and still breezing through the exams are long gone. Somehow in my youth I could do that, and still be able to quickly and easily barf out all the correct exam answers without thinking about it. I got a 99 in first year calculus doing exactly that, although it helped that the Central Technical School’s math department kicked butt, and left Prof Smith with only a review role.

Now I take a lot more time thinking things through, and also take a lot of time writing up my notes (which would sometimes have been spent better doing practise problems). It’s funny thinking back to undergrad where I had such scorn for anybody that took notes. Now I do just that, but in latex. I would be the object of my own scorn X10, if I met my teenage self again!
