Rutherford

Monday 27th April 2026, 12.55pm (day 5,359)

Rutherford Theatre, 27/4/26

Professor Ernest Rutherford, originally from New Zealand, was awarded the Nobel Prize in 1908 even before he conducted, with Hans Geiger and Ernest Marsden, the famous experiment where a bunch of alpha particles were fired at a sheet of gold and some of them bounced back, which Rutherford allegedly said was like firing a missile at a sheet of tissue paper and having it come back and hit you. From this was established the existence of the atomic nucleus, not to mention the original Geiger counter. For this reason Prof Rutherford is one of those former ‘Employees of the Month’ that the University of Manchester likes to big up. But in this case, why not? (Incidentally the room in which this experiment took place is still there, although no longer a laboratory — last time I looked it could be booked as a meeting room.)

Quantum proposition

Monday 16th February 2026, 9.15am (day 5,289)

Quantum theory, 16/2/25

Whomever stencilled this on Cross Street, Manchester, is obviously referring to the Many Worlds Interpretation of quantum theory — the idea that whenever a decision is taken, both possibilities play out, and so all possible worlds exist as parallel universes. Which is all very well but if, somewhere, I am the King of Norway — or banged up in a concentration camp for some perceived felony or other — or having great sex with Natalie Portman on a regular basis — the “I” that exists in this reality still had to go to work on this Monday morning. Another proposition then — it is what it is.

Bubble magnet

Tuesday 20th May 2025, 5.50pm (day 5,017)

Bubbles on straw, 20/5/25

I do not know exactly what principle of physics this straw is demonstrating, but I will take a stab at it: whether because it is black or not, it has absorbed and retained a certain amount of heat. Enough, anyway, to keep the liquid around it just that little bit warmer and thus precipitate out the bubbles. Sounds plausible, right? But I am guessing.

Making ripples

Thursday 24th April 2025, 5.10pm (day 4,991)

Goose ripples, 24/4/25

It’s a shame about the foliage but these are near-perfect ripples, and the impression I got was very much that the goose was just sitting there and making them simply because it could. A human equivalent might be holding a ruler down on a desk and making it go bdrrbbrrrddbrrdd. A pointless but pleasing application of physics.

In the Chemistry building

Tuesday 22nd February 2022, 2.40pm (day 3,834)

For the first three weeks of this semester I have been giving some classes in the Chemistry building, where resides this interesting display: I’m sure you realise what is going on here. As today was the last of these three classes, and I may never come back in here again, I thought I would capture it while I had the chance. They have omitted to include examples of the radioactive elements, but that’s probably a good thing.

22/02/2022 was today’s date, and a Twosday too: so Radon, to bottom right, perhaps is the most representative of these.

The robot greenhouse

Monday 15th February 2016, 4.00pm (day 1,635)

Robot greenhouse, 15/2/16

The reason I am in Wales is to do a talk at the University of Aberystwyth, which I did tonight. Beforehand I had a tour of this facility. Aberystwyth is well out in the sticks — for its size (which is not large), the most isolated town in Britain — and thus has a focus on rural and agricultural research rather than, say, heavy engineering. But that doesn’t mean high technology is just something other people do. This is a near-fully automated robot greenhouse, full of computer imaging equipment and automated water dispensing pipes. And you thought growing your food was just a matter of getting the weather right…

Potato clock

Monday 5th January 2015, 6.30pm (day 1,229)

Potato clock, 5/1/15

It’s a small digital clock powered by two zinc and two copper rods stuck into two potatoes. Hence, a potato clock. Well, the run of landscape shots had to come to an end at some point, but I guess we can still call this ‘nature’?
