We went to Tullie House on Monday to see the Roman helmet but we also found a brilliant work of art. They would let me photograph it so you'll have to make do with a photograph of the leaflet. Alternatively you can go to http://www.artfund.org/what-we-do/art-weve-helped-buy/artwork/11956/ocean
It is about 1000 small ceramic pots laid out to be like a wave on the ocean. Waves are a transient thing. They are hard to pin down. Do you draw a graph of them frozen in one moment in time or draw a graph of how a single point on the wave moves with time? I suppose Natasha Daintry has chosen the former. I like its simplicity. I should have measured the wavelength. The amplitude decreases. What would we give for the wave speed? The exhibition is in Carlisle until March - plenty of time to go to see it.
