Microfluidics

the next video shows microfluidic channel, note the slow diffusion into the neighboring channels after each new ink is introduced; also note that the different inks do not mix well but instead stay mostly separate (due to laminar flow).


and another video of a very simple microfluidic device showing separation, mixing and sorting

Peace and All

Nature holds healing powers for troubled souls, and by being at peace with all life on earth one finds that one is at peace with oneself

-Daphne Sheldrick

in fact, peace is necessarily a two-way road - having an inward and an outward component and it is not obvious who benefits more the receiver or the giver

Acquire peace and thousands around you will be saved

-St. Seraphim of Sarov
