Question: what do you think at night

Mariana Vargas answered on 15 Mar 2010:

Often I switch off from work and I think about fun stuff like planning a holiday, visiting family, etc. When I can’t switch off from work, sometimes I think about experiments, or writing up scientific papers. I must admit I have had some good “eureka” moments in the evenings when some answer I was looking for at work just appears out of nowhere in my mind at night while cooking dinner, and then I can solve a problem at work the next day!
