From Simon Goodman, Griesheim, Germany
As much as we, your readers, relish your impartial internationalism, I for one am peeved by the use of a particular unit of measurement – the “Statue of Liberty” – in your look at space start-up SpinLaunch (4 June, p 12). Is this more or less than a Nelson’s Column, an Eiffel Tower, a Petronas Tower or a blue whale?
I think some wise people had a good idea some time ago to create standard units, like the metre, which, relatively speaking, have stood the test of time.
