just need to vent… some days i wake up and i feel good… genuinely happy and productive… like all the things i find negative about my life are completely miles away because im better then that…feeling like even the small bit of progress ive made in what ever endeavor i struck out to achieve was progress non the less… then there are days where i just get washed over by intense overwhelming waves of sadness, insecurity, hopelessness, and negativity… so bad that looking in the mirror can be unbearable… going on facebook makes it worse as i see so many friends doing things for themselves and being successful…while im stuck in my situation (that i put myself in making it all the worse) like i wanna scream in my own skin but im muted by my own inability to even muster the motivation to do even that… and nothing will interest me or sound like a good idea to even do… so ill stare blankly at a wall… with my thoughts churning over and over in my head till finally if i even have the time ill just sleep…
i wish i was even half as brave as finn
When light travels through areas of different air density, it bends. You’ve probably noticed the way distant pavement seems to shimmer on a hot day, or the way stars appear to twinkle. You’re seeing light that has been distorted as it passes through varying air densities, which are in turn created by varying temperatures and pressures.
Schlieren Flow Visualization can be used to visually capture these changes in density: the rising heat from a candle, the turbulence around an airplane wing, the plume of a sneeze … even sound. Special thanks to Mike Hargather, a professor of mechanical engineering at New Mexico Tech, who kindly provided a lot of these videos.
