Isn't it lucky that years ago, when scientists were sorting out the Principle of Conservation of Energy, they didn't have exercise treadmills, toy cars or UKC to distract them?

It doesn't matter whether the speed of the treadmill is constant, variable between steps or variable within the step, during the step duration it will have tried to lower you vertically by a certain amount, which will depend on the treadmill speed, but the energy you have expended staying in the...

It's just about what happens to your Centre of Mass. When you step up on the treadmill you bring your C of M back up the same distance that the treadmill has lowered it. On the slope the same step lifts your C of M the same distance.

If your actions on the treadmill are the same as they would be on a smooth slope of the same gradient the energy is the same. On a real hill it may be different, as has been pointed out.

I agree with all of that. I also think the JH, Block Hall, Ventilator, JH circuit is not the place for SRT novices. Eldon Hole is somewhere you can look after those novices, rig a couple of routes for variety and is spectacular. The Peak "tourist trip" taking in Far Sump and the far end of...

It certainly is. They would be potholing pendants.

I don't think either of those things is a concern. It just isn't necessary very often when big pitches are split as they frequently are here. I have tandemed Titan 3 times when trips were running late and Whalfe Engine Shaft once. The only problem that became clear was that if the top person is...

Isn't it odd how you can understand all the words - except perhaps one - and still have no idea what it's all about?

On my Picos (the Amazonia 2 looks similar) I eventually sorted that problem in the same way as JoshW described. The other problem was that one of those short connections - it was always the same one but now I don't remember which - quickly used to move to the centre, making it uncomfortable and...

Yes that's the way things are supposed to work. Back in the day the light switch was a normal ceiling-mounted pull switch, with the usual twin and earth cable to it - live and switched live. When it was replaced by an occupancy sensor (which has its own active circuit) a neutral would have been...

I think that's the isolator for the extractor fan.

Yes it does. The notion that people can't think for themselves or make decisions without specific training is a very modern, and very strange, idea.

But where does that lead? To the idea that if an employee hasn't specifically been told to do/not to do something, no matter how daft it might have been, they are not responsible for what happened to them? That can't be sensible.

Perhaps just the memes.

I have always wanted to be awesome.
