A personal message from me (Dna-Dennis) to fellow Wikipedians
I am not very active anymore on Wikipedia, therefore I hope that users who post messages here don't feel offended if I don't respond to requests. I hope, trust - and leave it to - other wikipedians to carry on working on and/or altering things I have created for Wikipedia (e.g. various maps, diagrams and images etc). I'll surely check here on my talk page now and then, but please don't expect me to take on any work at the moment; if I feel the urge I will do so, but - it's purely up to me :). Throughout the years I have talked to and collaborated with many professional and friendly wikipedians, and I am very thankful for this fruitful and interesting experience. I'll surely participate in some way concerning scientific articles now and then, tweaking a little here and there. Dna-Dennis (talk) 17:08, 20 January 2012 (UTC)
Gravitational Constant
What is the meaning of the parenthesis in the gravitational constant? — Preceding unsigned comment added by 24.16.182.40 (talk) 16:20, 8 March 2012 (UTC)
- Hi, the parenthesis is the uncertainty (+-) of the measurement(s). See Gravitational_constant#Laws_and_constants and Uncertainty#Measurements. --Dna-Dennis (talk) 21:09, 8 March 2012 (UTC)
Defining celestial & elliptical
Ty for the graphic showing the celestial poles, etc.
I found it via google.
Could you explain on your graphic why they'r called celestial, and what elliptical means in the context of your graphic?

space travel
earth rotates east to west at 17000 mph, and the shuttle obits at the same speed. If the shuttle is orbiting on the same trajectory as earth east to west would it appear stationary in the sky? 50.72.67.195 (talk) 21:17, 1 December 2012 (UTC)
