So the power goes out while I'm in the middle of writing. Not a problem – I just lost about 10 mins of work. The experiment I was running should be ok as I have the waterbath on the emergency power circuit. Or so I thought. Uho, panic with cursing – I'm about to lose a two day experiment which just needs another 24 hours to complete.
Fortunately, the power came back on before the temperature of the waterbath fell too low. Now I have to find out why that electrical circuit is no longer on the emergency power line.
