We often think of raindrops as spherical or tear-shaped, but, in reality, a falling droplet’s shape can be much more complicated. Large drops are likely to break up into smaller droplets before reaching the ground. This process is shown in the collage above. The initially spherical drops on the left are exposed to a continuous horizontal jet of air, similar to the situation they would experience if falling at terminal velocity. The drops first flatten into a pancake, then billow into a shape called a bag. The bags consists of a thin liquid sheet with a thicker rim of fluid around the edge. Like a soap bubble, a bag’s surface sheet ruptures quickly, producing a spray of fine droplets as surface tension pulls the damaged sheet apart. The thicker rim survives slightly longer until the Plateau-Rayleigh instability breaks it into droplets as well. (Image credit: V. Kulkarni and P. Sojka)

the moment you realize
that your bones are made of the same dust
as the planets, 
your lungs are breathing the same air
as the migrating butterflies,
and your blood is pumping because
of the love and care of thousands;

is when you realize
that you are not as broken
as you think you are. 
you are full
of the world.

I hate this pseudo apathy that everyone has nowadays, like they think it ain’t cool to care about stuff. Well let me tell u son, there are lots of cool things to care about like dogs and space and holding hands and science and music and art and how the sky looks when the sun sets, and if u think you’re too cool to be passionate about something as incredible as this life then thats really sad and idk what to tell u

People say I love you all the time - when they say, ‘take an umbrella, it’s raining,’ or ‘hurry back,’ or even ‘watch out, you’ll break your neck.’ There are hundreds of ways of wording it - you just have to listen for it, my dear.
