Antique Barometer - Objectivity 243 

I agree something with them together would be cool, but Keith’s been on The Conversationalist and Brady hosts like three podcasts

A Podcast would be nice

I want a travel show hosted by them xD

It would be interesting to hear Keith let loose and deep dive into a topic. Alternatively, mic him up and just let him go...

I would happily produce a podcast for them for free, just to get their knowledge and passion documented further! :)

Agreed.

Thanks for watching!

You're welcome.

I think it's unlikely that's intentional, it would be very fussy indeed to get right and would have no benefit

That's a wonderful motto you just propose Sir! Indeed, the mind seems to stay on track if it starts with Keith and Brady approach.

Well, getting it to 1/60th of a degree... might count as two additional digits. :)

Quite some stuff is being stored on digital photographic film in the permafrost seed vaults. The film with its plastic base should last for centuries. I think they started with putting the complete github contents in the vaults. Paper has the benefit of containing information that can be interpreted mostly without technology, but it is not necessarily more reliable than digital storage. HDDs are hermetically sealed these days, so even if you leave them out in the weather, if you really want you can retrieve the data that is mostly unharmed on the platters. Leave paper in a damp cellar for a century and it's completely gone. The HDD's electronics won't work, but you can take out the platter and use professional equipment to read it out. If the information is world-shakingly important, the professionals sometimes even use electron microscopes to figure it out.

The main scale reads to 1/2 degree, and the vernier lets you measure to the nearest minute (1/60 degree). Not too shabby!

Yes, it looks like there are subdivisions for degrees, for half degrees and then a -15 to 15 Vernier scale for the half degrees.

That's the same as I got. 1 minute of arc via vernier.

@@WhatAboutTheBee indeed. I read about 289°38' (from 5:01)... would you agree? maybe 39'... not sure.

@@DavidLindes 289°39' is what I read. It is the smallest pinch off of 38', but could arguably been that. For curiosity and amusement, I happen to posses a Circle of Reflection. There are two verniers, mounted on an arm that bisects the circle of arc. In use, the two readings are averaged, providing a measurement to 5". The arm removes centering error, making the Circle of Reflection a highly accurate measurement tool.

I think it's a feature of older hotels, before we had semi-reliable weather forecasting. I've seen it here in the States a few times, but never in a place built within the last couple decades.

1/60 actually (a minute of arc). The main scale is in 1/2 degrees.

Good spot! I bet you're right: he was certainly a member of the Society and published in the Proceedings, and he was widely known as Dr Franklin at the time because he'd received honorary doctorates from St Andrew's and Oxford. Surely Keith will be able to confirm it for us.

Yes. One can measure angles down to 1/15th of a degree with that protractor. Good luck finding an instrument today that can do this (without paying a fortune).

@@renerpho 1/60th, I believe. The divisions on the main dial are ½ degrees, and then the vernier goes 0-15 on one side, and 15-30 on the other... so, 0 or 30 minutes from the main dial location, plus 0-29 additional minutes from the vernier.

There are probably more counties it it's older than then counties it is younger than
