Maybe I shouldn't have started this blog now, not with everything that's been going on.

In the meeting of the first of my two Engineering Drawing and Design classes for the ninth week of the first term, I started on the floor plans.

Even though I had warned some of them to get the building lay out of the new Integrated School building for their next exercises, I actually just told them to recreate how their home looks like. Now at this point I don't want to sound elitist or anything, but we were having fun at the expense of some students complaining that they had too many houses to show, and they had too many floors. At the same time, there were some students joking that since their house was only one room, would it be alright to also include the railroad tracks right beside the house.

I also told them to come up with their dream house for their next exercise (like their idea of what the school would look like in ten years, just to test their own creativity) but they complained that there wasn't enough time.

It looks like I have the next three weeks of this class planned out already because of that.

In the second meeting of my Engineering Materials Science class for the week, we finished with Chapter Five of the textbook, about diffusion.

At the start I tried to review them on the concepts that we took up the day before, about the Fresh Maker principle of alloys, that it had to be treated to high temperatures to get a surface concentration of higher (and thus stronger) than the inside. But the formula that we discussed during the last lecture did not contain the temperature.

So that was the last equation I showed them, which I also said was linear, but included an expression for an exponential. Therefore it could also be given as a formula with logarithms. Since it was linear there are some parts of the equation that is the same as the slope, and another that is the same as the y-intercept. That meant those were two new (old) equations that could be added for deriving values needed by the problem.

I gave them several examples afterwards, one of which used all the equations discussed so far.

Session 1217 is soft outside. Class dismissed.
