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
My interests
[edit]
|
I am an amateur radio operator |
As amateur radio I have been licensed since 1994 using now CW qrp and RTTY and occasionally other digital modes. I'm using French, English and Spanish to communicate. My hobbies are collecting photos of official post boxes from everywhere especially the pillar boxes because I suffer from puxisdiphterophily (don't worry it is good for health !).
I am also interested in heraldry. My other interests are astronomy and rugby. For further info please wait to let me time to write down on this page. See you soon ! ¡ Hasta pronto ! À bientôt !
