Got it in 4
would have been 3 except I was on my phone and mistyped my first word!
Happy to explain how I did it tomorrow.
Yesterday I took about 40 - I decided to have a stab at the individual letters because there were so many of them in all the citations at the bottom: that gave me a book title "Q is For ....." and I guessed Quantum and Quark, which lit up the page like a fruit machine, after which it was pretty simple. But if all the ups and downs immediately made you suspect quarks then you'd be quicker than that because I wasted 15 guesses on letters of the alphabet.
