X-rays are a form of high-energy electromagnetic radiation, with wavelengths shorter than those of ultraviolet rays and longer than those of gamma rays – roughly in the range of 0.01 to 10 nanometres. X-rays were discovered by German scientist Wilhelm Röntgen in 1895, who named them X-radiation to signify an unknown type of radiation. X-rays can penetrate many solid substances such as construction materials and living tissue, and X-ray radiography is widely used in medical diagnostics. This medical significance was noticed by Röntgen shortly after he discovered X-rays; this print, titled Hand mit Ringen (Hand with Rings), is a print of his first medical X-ray, taken of his wife Anna Bertha Ludwig's hand in December 1895.Print credit: Wilhelm Röntgen; restored by Yann Forget

Hello Sunborn
editI made some edits to a page you had previously worked on. My comments about the recent round of edits to the List of Zeta Psi chapters is on the Talk page. If you have continuing interest and time, I'd welcome your review. You'd also be welcome to join the Fraternities and Sororities Project. If I read correctly your reasons for semi-retiring, I concur that edit wars and Deletionism has been a problem. For us, we police these articles within our area of interest, and have kept the Deletionists and other trolls at bay. We now monitor several thousand pages, and are actively improving them.
