Bessel function
I reverted your change to the limits of the asymptotic forms on Bessel function page, since it was incorrect (see e.g. the Arfken and Weber reference); this was actually discussed extensively in Talk already. Please be more careful when editing mathematical pages, and give references for your changes; if you are not sure of something, it is a good idea to discuss it in the Talk page of the article first.

London Equations
Hi There. As you appear to be the original contributor to the London Equations Wikipedia page, I'm contacting you to ask whether you have a high resolution image of the two London Equations shown at the top of the page that you might be kind enough to supply to me. Heinz London is my grandfather, and I'm looking for a good quality image of the equations to have printed in a larger format. Thanks for your time.JeremyLondonNZ (talk) 22:52, 26 July 2016 (UTC)
