It is always great to realise that we have enough time to head across town to enjoy a coffee at Pritchard & Ure. If you haven’t yet tried it, Pritchard & Ure is a lovely spot in Camden Garden Centre (near Camden Road overground station). I first visited back in 2018 and ordinarily, I would not do a second cafe-physics review. But then 2020-21 have not been ordinary either and Pritchard & Ure too has changed. Back in 2018, a swaying pendulum prompted thoughts on how we knew that the Earth rotates. Since then, the world has moved in a different way.
In the case of Pritchard & Ure, this is reflected in a definite physical change to the cafe: a new terrace has been built overlooking a semi-outside section of the garden centre. This bit of the garden centre is sheltered from the rain by a permanent roof, almost like a permanent umbrella (see picture). The cafe on the other hand is protected from light rain and wind by a series of garden umbrellas. Apparently the indoor section of the cafe remains open if the weather becomes too awful (or presumably in autumn/winter). But in these times when it is good to be able to socialise outside, the new terrace offers a perfect place to do it. Accordingly, I took the opportunity to have an oat milk latte. While black coffee is normally a good test of the coffee in a cafe, I knew Pritchard & Ure served great coffee from my previous visit. Roasted by Workshop, the coffee is still offered in either a 6oz or 8oz size. But it’s been a while since I had enjoyed a properly made latte in a cafe and so why resist? We also enjoyed a spot of brunch, all while admiring the number of plants (and cacti) on view.
As before, obvious thought trains went in the direction of the science of plants and ecology. The large number of cacti just below our table was particularly suggestive of the changing conditions of our planet and the tendency for some areas of our world to be subject to more drought. The flowering plants too could prompt reflections on insects and how climate change is affecting them, including the possibility of mass extinctions. The past couple of weeks have seen Extinction Rebellion back in London as we prepare for COP26. One action that they took was an occupation of the Science Museum. The museum was targeted because Shell sponsor some of the exhibits including the “Our Future” exhibit about climate change. Extinction Rebellion have written an open letter to the Science Museum arguing, amongst other things that Shell gains “prestige and implied endorsement by the Science Museum group”. This is despite Shell’s own business plans not being “in line with limiting warming to 2C“. The museum disagrees with the principle of boycotting sponsorship by Shell on the grounds that such companies have the “capital, geography, people and logistics” needed in order to fight climate change. They also argue that some of these exhibits which help to inform the public about issues such as the science around climate change are only possible because of the financial muscle of companies such as Shell. It is a tough ethical cookie. One where we may have to try to read about the arguments and yet withhold judgement, knowing that most of us do not know enough, or have not thought deeply enough, to comment authoritatively.
A somewhat similar issue concerns the site of the garden centre itself. At the beginning of the 19th Century, the land belonged to William Agar (hence Agar Grove just north of the garden centre). Agar himself lived in Elm Lodge which was approximately where Barker Drive is now. He was involved in a dispute with the Regents Canal Company. He did not want the new canal to cut through his land. Finally, at the end of 1817 he relented and now, the canal cuts NW to SE just west of Pritchard & Ure. Was Agar a NIMBY (not in my backyard) or was his objection more complex? It’s another issue on which we have to suspend judgement. Though maybe this is easier to do as the case is over two hundred years old. Would we be so balanced if the Regents Canal were being built now and we wanted to react quickly on Twitter? What if the Regents Canal were HS2?
A more physics-based issue of balance could be seen in the umbrellas arranged over the terrace. They were supported not centrally but from the side, so the umbrella could be easily placed above the tables without the supports getting in the way. Immediately we could make connections to counterbalances and cranes. How is it physically possible that such a weight can be held by an outstretched (mechanical) arm? The weights of the flower pots standing on the umbrella bases may give us a clue.
There were many opportunities to think about issues of physics or balance on this terrace. It was a reminder of how good it is to go to a different cafe, put aside the smart phone, and just sit, enjoy a well made coffee and ponder about any subject that strikes your mind. Pritchard & Ure is a perfect place to do this, it remains a friendly space with good coffee (and food) at which you can enjoy thinking. And now, with the outside terrace, there is even more reason to go there as it is rare to find a cafe close-ish to central London with a large outdoor, and socially distanced, seating space.
