This #clock face is full of bubbles because the fast-curing #epoxy was already warm from the reaction when I added the pigment and poured. The result was too good to throw away and I decided it would make a nice clock face. I painted on the hours in unblended Winsor & Newton Galeria acrylics colors, using polar graph paper taped to the back as a guide. https://www.instagram.com/p/C7o-1PWRt9_/?igsh=MTh4dDRlNzM3c2E4
I've been feeling exactly like this comic, but I got a cheap retro alarm clock and started keeping my phone in the living room at night. It's really nice
If you use the clock app on Sonoma to set a timer, when the timer goes off... it never stops. You can't stop it. You can't kill it. It goes on... forever...
John Barras and Co clock outside a former pub on Victoria Road on the Southside of Glasgow. John Barras was a brewing company founded in 1770 and based in the North East of England. In the 1890s, it merged with three other local brewers to create Newcastle Breweries, who would go on to launch Newcastle Brown Ale in the 1927. In the 1960s, another merger took place with Scottish Brewers to create Scottish and Newcastle Limited.
Built in the 1870s for the City of Glasgow Union Railway and designed by John Fowler and James F. Blair, Saint Enoch Station was once the grandest station in Glasgow. It was closed in 1966 and then demolished in the 1970s. This clock, which hung inside, is pretty much the only part of it which remains.
After the station was demolished, the clock was purchased by the businessman Raymond Gullies, who donated it to Cumbernauld when the new town celebrated its 21st birthday in 1977, where it was erected on a public walkway and featured in the 1980s film Gregory's Girl. In the 2000s, it was moved into the new Antonine Shopping Centre when Cumbernauld town centre was redeveloped.
In recent years, there have been calls both to return it to Glasgow for installation in Queen Street Station, and to have it re-installed in a more public space in Cumbernauld. However, for the moment it remains in the Antonine Shopping Centre in a closed off section where it can only be viewed by request, which is a sad state of affairs for such a grand public clock.
«Given the Moon’s weaker gravity (and movement differences between it and Earth), time moves slightly faster there. So an Earth-based clock on the lunar surface would appear to gain an average of 58.7 microseconds per Earth day. As the US and other countries plan Moon missions to research, explore and (eventually) build bases for permanent residence, using a single standard will help them synchronize technology and missions requiring precise timing.»
Coming up with some (presumably) correct + still reasonably short description seems more challenging (to me). My best attempt so far:
<blockquote>
<b>If</b> two astronauts had met "somewhere in (cislunar) space", and subsequently separated from each other,
with one astronaut venturing on to land on the lunar surface, and
the other astronaut returning to the Earth's surface,
such that (as may happen in selected trials)
it takes both astronauts exactly equally long, resp., from separating until reaching (halting on) the Moon, or on Earth,
after some (not further specified) while, either astronaut perhaps being prompted by suitable prearranged signals,
both again take off from Earth, and from the Moon, resp., and they meet again "somewhere in (cislunar) space", where again (trials must be selected such that)
the duration of one astronaut from her take-off until the re-union meeting
happens to be exactly equal to the duration of the other astronaut from his take-off until being together again
<b>then/therefore</b>
the astronaut who had stayed on the lunar surface had remained there
(pretty much) <b>exactly</b>
[\left(1 + \frac{58.7 * 10^{-6}}{86400}\right) \approx (1 + 6.8 * 10^{-6})]
<b>times as long as</b>
the astronaut who had stayed on the the surface of the Earth had remained there.
Les deux pivots cassés du balancier d'une montre à échappement à cylindre, équipant une pendulette en bronze doré.
Réparation pas cool car très hasardeuse en temps, en réussite, et périlleuse car il ne faut pas briser l'écorce du balancier.
Le principe? Enlever les tampons (comportant les pivots) de chaque côté de l'écorce. L'écorce est un tube creux de 1mm de diamètre. Sortir les tampons avec un outil particulier, tourner le plus long au tour pour reformer un pivot et remplacer le plus court.
Vidéo de la mise en marche forcée (avec le doigt forçant la rotation du rouage) pour voir si la réparation a fonctionné.
Y'a plus qu'à réviser le mouvement et ce sera bon!

Can we control an entire distributed circuit in the brain? If not now, when?
Neurotechniques can do amazing things. One can target a population in region A to track specific projections to region B, and then study the impact on B.
How far beyond that can we already go? What is the most extreme example that you know of open- or closed-loop manipulation?
