[Raak] Could I ask a major favour? I have a mathematical problem I think I've solved, but I need someone with a mathematical head to give a thumb-up or a thumbs down, and maybe to insert a few equations translating some of my prose into mathematical language. Would you be willing to help out? I know you've done the odd bit of recreation mathing in the past - there was your paper on Culture orbitals for example. This is another in that vein. I have found your professional email address online, but I wouldn't just fire off a random message without checking first.
