Who needs a pendulum when you have a rolling metal ball?!

I cannot imagine what sort of naughty words Alan Middleton might utter upon the introduction of his forearm to a spire

Would like to see another episode with Mr. Middleton in the future, including some more of his anecdotes.

Clock on his tie even - this dude really like clocks! Interesting video as usual :)

Is the second rolling-ballclock more accurate than the first? I'd imagine the skeleton plate reduces friction and dirt buildup, and being built in the last 20 years or so would mean more precise mechanics etc.

@francoislacombe9071 6 жыл бұрын

No clock is perpetual of course, but there is a kind of clock that never needs winding. They contain ingenious mechanisms that extract energy from variations in air pressure, kind of elaborate barometers. The institute probably has at least one specimen of such a clock, it would be great if a video was made about them.

Francois Lacombe I do believe you are talking about the Jaeger-LeCoutre Atmos clock.

@Derkman96 6 жыл бұрын

Could something like that be considered "functionally perpetual" if that makes sense? Like is there any likely situation that would cause that mechanism to stop? Why isn't something like this used for energy aside from clocks? Is there just not enough energy to be gained from barometric pressure change?

@bbgun061 6 жыл бұрын

+Derkman96 - You're right, there simply isn't enough energy in the air to run anything requiring more torque than a clock. It's not a perpetual motion machine because it requires external energy input.

"Well while I was winding the clock I drew my arm away rather rapidly... and... well there was a good deal of blasphemy that took place!" What a posh way of saying "I cut my arm open and swore a lot"

I am impressed by the clock. Thanks royal society. And objectivity.😊😊

Brady, you cannot make enough videos about these clocks. This is absolutely fascinating and I can't wait till you release another one. Could you perhaps feature the most accurate clock at the institute?

I've had a really clever ball-based clock design waiting in my head for decades, but I don't have the engineering skills to build it. Don't really have the time either. One day, when I'm retired...!

There is one of these in the Science Museum, too. Was always about 2 seconds too slow for every 30 second interval

@fisheatsyourhead 6 жыл бұрын

I'm sure with modern manufacturing and design you could make a much more accurate model of a similar mechanism but considering what it is it's really not that bad

@Jackarooo 6 жыл бұрын

The problem with the mechanism is not the old manufacturing or design, the problem is the randomness and unpredictability of the ball meaning that the mechanism will never be very accurate.

If any of you are interested in awesome clocks, Chris from Clickspring makes one from scratch. He makes a large-wheel clock in a series of videos.

This was really interesting, after I watched the video I checked to see if I could visit, shame they aren't open again until spring 2018.

The pointy "finials" are clearly to get the blood sacrifice that the spirits driving the clock require in order to continue their labors.

Ok, whenever you want, you can do more clock videos.

What happens if you hermetically seal the clock to keep dust out? (As for winding: maybe you could do something with magnets or something of that sort.)

@CocoTehQuila 6 жыл бұрын

If you have a pendulum of 1m, you get a half frequency of a second. This was one of the first proposition for the definition of the meter.

I want to find a nice museum where I can see an atomic click. With a 10MHz output that they'll let me plug an osciloscope in to. I have a OCXO frequency standard that needs calibrating.
