Brochure boy
I recently found this photo in a pile of old climbing magazines. It was taken when I was a student at Leeds University. I'm pouring liquid Nitrogen into the outside jacket of a flask containing liquid Helium. The Nitrogen came in buckets the Helium was on tap. I can't remember what the experiment was about but it had some connection to superconductivity. I had to move more apparatus onto the bench for the photographer so some of it might be spurious. If you are very observant you might notice the scabs on the back of my hand. They aren't liquid nitrogen burns but hand jamming scars. Hand jamming is a way to climb cracks. You put your hand in a crack, flex the muscles to make it bigger then pull up on it. If the rock is rough and your hand slips then you get cut. This photo used to be in the Leeds University prospectus, I wonder if my scabs put people off applying?
