Impressive Shorts!

That's amazing..

This makes me so happy.

Fascinating demonstration.

This video demonstrates one of my favorite effects: the reversibility of laminar flow. Intuition tells us that un-mixing two fluids is impossible, and, under most circumstances, that is true. But for very low Reynolds numbers, viscosity dominates the flow, and fluid particles will move due to only two effects: molecular diffusion and momentum diffusion. Molecular diffusion is an entirely random process, but it is also very slow. Momentum diffusion is the motion caused by the spinning inner cylinder dragging fluid with it. That motion, unlike most fluid motion, is exactly reversible, meaning that spinning the cylinder in reverse returns the dye to its original location (plus or minus the fuzziness caused by molecular diffusion). 

Aside from being a neat demo, this illustrates one of the challenges faced by microscopic swimmers. In order to move through a viscous fluid, they must swim asymmetrically because exactly reversing their stroke will only move the fluid around them back to is original position.

Never seen white northern lights..

Life goals, some day I want one like this...

Have to remember this...

The perfect length of time to be on vacation is 8 days. Your health and wellness levels rise rapidly while on vacation, but they peak on the 8th day and return to baseline within your first week back no matter how long you’re gone. Because lengthier vacations don’t seem to make a difference, experts say the key to improved overall satisfaction is to take more vacations, not longer ones. Source Source 2

Blizzard banned pro Hearthstone winner for supporting free Hong Kong and took away his prize money. It would be SUCH A SHAME if Mei became a symbol of Hong Kong democracy and got Overwatch banned in China like Pooh did.

Join us! Draw this in your style or any blizzard game characters as a Hong Kong protester. Don't let the Chinese government control our free speech!

Well written.

Love this detail..
