I bought the old book from which the background of this collage is taken many months ago, it is full of engineer’s formulae, tables and diagrams and I fully expected to make frequent use of it, but so far this is its only appearance and even this has been lurking about for many weeks.
I think the poor thing has rather given up hope of being posted but as I have nothing else worthy of a public showing at the moment I will give it a try.
P.S. 2nd Ashes Test, England win by an innings and 71 runs!!
