From Oliver Higson, Berlin, Germany
I write regarding Adam Vaughan's excellent article on why the UK has one of the highest death rates per million from covid-19 in Europe ( 6 June, p 8 ). I live in Berlin, where face masks have been mandatory for more than a month on public transport, in shops and in any place where …

He is colour-blind, but I am not, so I can never comprehend his subjective experience of seeing a rainbow, nor he mine. All the optical and neurological science in the world can never change that.

From Liz Bell, Great Shefford, Berkshire, UK
I have been following the debates in New Scientist about whether we are all living in a simulation ( 6 June, p 30 ).
