Hello, I'm K6ka. I wanted to let you know that I reverted one of your recent contributions —the one you made with this edit to Speed of light— because it didn’t appear constructive to me. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. --I am  k6ka  Talk to me!   See what I have done  16:50, 29 October 2015 (UTC)
