Material properties
Toby: That’s certainly a scary-looking collection of tools.
Ester: Yes, some of them do look quite menacing, don’t they?
Toby: Is that titanium? The drill handle?
Ester: Um… yes.
Toby: I’m an engineer, that’s why I, am…
Ester: Oh, I see. Yes, titanium’s great. It’s expensive, obviously, but very light. That’s the advantage. Ideally, you want it to be lightweight, to give better control.
Toby: Nn…
Ester: These are the most impressive things, though, the burs on the end. The latest ones can rotate at over half a million revs per minute.
Toby: Nn.
Ester: They are coated with tungsten carbide, which I think is one of the hardest materials in existence, isn’t it? Along with diamond. That’s also used.
Toby: Nn.
Ester: The requirement is abrasion resistance, of course. Obviously, they need to be very durable. And you don’t want them snapping either. The last thing, you want is brittle material. Apparently, that was the trouble they had in the past, making the bur tough enough so it didn’t break. I think part of the problem was heat, as well. Drilling into a tooth at high speed, you obviously get a lot of heat build-up. You need a good degree of thermal stability.
Toby: Nn.
Ester: See what I mean? You can actually smell burning. And that’s after a few seconds. Imagine the heat build-up after several minutes.

Unit 14 NUMERALS
When I was a kid I was top of the class in maths. I was really good at mental arithmetic and doing sums. Things were easy back then, It was all addition and subtraction, multiplication and division. I knew my times tables like the back of my hand. Then, things got difficult when I was about 14. We had to learn stuff like algebra and geometry and lots of other stuff I can’t remember the names of. Suddenly. I wasn’t so good at maths any more. I think there were a few reasons for this. One was my maths teacher, another was because I sat at the back of the class, and another was I talked a lot. I still like maths and know I would be good at it again if I studied. I did statistics when I was at university and loved that.
Unit 15 GEOMETRIC FIGURES
3-Dimensional
3-Dimensional, 3-Dimensional, this means the shape or something has three dimensions that means a curves up and down, side to side and front and back. That is 3-D. The opposite would be 2-D. So on the computer screen everuthing is 2-D. This is up and down and side to side. For 3-D you need 3-D classes for depth perception.
