Crow Instability

Description

:star: Witness the power of nature...:star:

Wish I got a better shot of this, but I was shooting a high school football game for yearbook so I had other responsibilities =D Looked up above during the game and saw this awesomely-shaped contrail. This phenomenon is called crow instability. The chromosome-like shapes are caused by the wingtip vortices interacting with the contrail vapor. :nod:

Soo, I'm crazy for wanting to investigate stuff myself, am I? So much for the 4 years of philosophy studies then, all wasted down the drain... Typical narrow minded academics to trump on those who dare to be a true human. With your academic background you should know that we're all born with the desire to explore the world and through own studies reach our own conclusion. But then again, the school system has gone down the drain generally since the 70's. The only thing we learn today is to obey and accept facts as being absolute regardless of source or trueness. Consensus has become based on capital rather than objective, independent research, while the kids learn that the only objective source of info is the per-viewed "science" that more and more becomes fiction. To me that's the definition of hypocrisy and nothing to be proud of being a part of. Of course I can't force my opinion on others, and wouldn't if I could. Nor will I reaggregate to condescending treatment against those of a different opinion than me. Cause it isn't civilised, and that's an irrefutable fact. Have a good day.
