Query: An Imitation Game concerning gravitational wave physics   The 'Imitation Game' is a Turing Test played with a human participant instead
of a computer. Here the author, a sociologist, who has been immersed in the
field of gravitational wave physics since 1972, tried to pass an Imitation Game
as a gravitational wave physicist. He already passed such a test in mid-2000s
but this test was more elaborate and compared his performance with that of
other kinds of physicists and with other sociologists as well as gravitational
wave physicists. The test was based on 8 technical questions about
gravitational wave physics asked by Professor Sathyprakash of Cardiff
University. Collins marks compared well with that of the other gravitational
wave physicists and were markedly better than that of other classes of
respondent. Collins also marked the test and it can be seen that the way he
marked was also much closer to the gravitational wave physicists than other
categories. Though Collins's expertise can be shown to have degraded a little
in the last ten years it seems not to have degraded a lot. This is important
for his most recent book on the detection of gravitational waves from a black
hole binary, this being Chapter 14 of this book, which is due to by published
my MIT Press in February 2017.
