The Exchanges

Every argument clarity score on this site is built from rows on this page. Each question and answer was assessed with names hidden, the host's own answers included, on four things from 1 to 5: directness (does it answer the question asked), coherence (do the ideas follow), precision (concrete details and clear references), compression (says a lot per word). The weighted mix (30/30/25/15) is the exchange score. A person's published score averages their exchange scores on raw tape only, at least 8 of them, shrunk toward the cohort mean. Full method →

Keith Alexander no published score: no usable exchanges on raw tape, and a fair score needs 8+ · coarse estimate ≈4.5/5 from 6 produced feed exchanges record → ← everyone

Every exchange below was scored with names hidden, four dimensions each from 1 to 5. An exchange's score is 0.30·directness + 0.30·coherence + 0.25·precision + 0.15·compression. The published score averages the raw tape exchange scores and shrinks small samples toward the cohort mean, so five great answers can't beat twenty good ones. Produced feed rows count only toward coarse estimates, never toward a full score.

Q Wow. So what, what were some other things that you came up with, or you tried to invent?

A Well, for the art exhibition, we had, there was quite a few there. Uh, one, one of my enduring experiences was having a haircut during my PhD at university, and this young ditzy lady was giving me the haircut, and she said, do you realize you're thinning on top? It was really embarrassing, so I thought that would be a good thing for young guys to have, because you can never see the top of your head. So I made this, Board patch inspector is, that's what I called it. So there's a couple of mirrors, so you look in one mirror, and you can see in the other mirror, and you could move the levers, and it would adjust the mirror, so you could can see the top of your head.

Q And what, by the way, what made the enclosure different? How were you able to create this thing that was safe?

A So Steve said, we've now got a relationship with the people who make the pultruded fiberglass. You've got to make the poles out of those same material. And I said, well, they need to be strong enough to hold this net up. So I thought, well, can we, we can try it. Had a postgrad student who's needed some money, so he's working in our backyard. We got these, 12 of these around the trampoline, fitted on, and tied the top of them together with, with some cord. Let's see what happens when we put a net on. So I said to this postgrad student, you've got to spend the next few days finding some sort of net. Talk to all the fishermen people around the place, see if we can get some net, and after about four days he'd come back with some fishing net that he lashed on there at the top and the bottom, so it was more or less like an enclosure and in a sense different than the ones that were out there, but it was this really flexible thing, and so then when I came home from university and the kids were still on it, they were bouncing off the walls. They were running into it and bouncing off. And I'm thinking, hey, this is really something we didn't expect. We've got a new play surface here that other trampolines don't have. We've made a rubber room now. This is way better than I expected. It's not just a safety net. This is another play surface.

Q And Keith, what, what about you? Like, do you feel lucky that all this happened, or, I mean, do you think it's just a product of your persistence and, and perseverance and grit?

A It's, it's both of those, of course it's both of those. I do feel very lucky to have met someone like Steve who's been prepared to be very persistent. One of the ways I like to think of it, for me, the invention process, it's my part of it, is that it's, it's like having a child. The moment of conception is quite exciting, and then you carry it and you feed it for years, and eventually it starts to meet people of, of its own. And then you get less control, less and less control, and who your child meets, and where they go, and how they grow up, there's not very much in your control at all. There's a lot of luck there. So, in that sense, I've been very lucky as Steve's taken over the part to get it to the customers, so I was doing pretty well.

Q So just to, just to get a sense of when this is, we're talking about the mid-nineteen nineties here, right? Like 95, 96, somewhere around then?

A I started at university in 96. I ran a couple of university projects in, uh, 96, 97, uh, and I gave them pretty close guidelines because I put a lot of thought into it. Here's a way I think we could do it. Could you build one? Could you do the analysis on it? And at that time, I had this idea in my mind, and I found it very difficult to imagine. I'd never seen anything like it. It was a bit like a basket with the, these are, these are things, say, like fishing rods. Obviously, if you caught a fish on the end of a fishing, with a fishing rod, that's going to bend. It'll keep some tension on. It's flexible. Keep some tension on it. Maybe I could make one like that.
