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

In the second meeting of my Engineering Materials Science class for the seventh week of the first term, we started on chapter 4 of the textbook, which was about imperfections in solids.

This is since we have been establishing crystal lattice structures in the previous chapter, now we have to learn exactly how they exist in nature. First there is a thing called vacancy.

Vacancy is a measure of strength for materials. The more vacancies there are in the in a material, even if it is the strongest physical structure, there will be a measure of brittleness.

From there we went to alloys, which - technically speaking, is still considered an impurity in elements. Then it was just all equations about the mass or weight ratios of the elements in an alloy, or the atomic ratio, or the volume ratio.

Now most of these things I wrote on the board except for what the symbols were supposed to mean, which I had intentionally left out for the purpose of making Deiv listen to my lecture.

I even told them to spend the first part of the class (around fifteen minutes) copying what I had written on the board to ensure that they would be listening to the explanations.

And yet, despite all that, Deiv still kept asking questions about such simple things as what the symbols in the equations meant!

So it isn't just that he was too busy copying before to listen to the lecture; maybe he really does have an attention deficit disorder. So that's another thing I could call the guidance councilor on him for, and not just the physical ailments at the start of the exams, from three separate subjects.

Session 1203 needs a special school. Class dismissed.
