I'm a guy that likes things. A lot of different kinds of things.
Acoustic Levitation
Using sound waves to levitate individual droplets of solutions containing pharmaceutical drugs and drying them in mid-air. Why do this? This is useful because most of the drugs on the market are either amorphous or crystalline and the crystalline form doesn’t get absorbed by the body. So levitating the solution allows the drug to be made into an amorphous state (by evaporation) because if it were to touch any surface it would simply crystallize. They call this “containerless processing”.
The frequencies used are just above the audible range at about 22 kilohertz and when the two speakers are aligned they create two sets of sound waves, perfectly interfering with each other creating a phenomenon known as a standing wave. This allows the objects to levitate in areas within the waves known as nodes as the acoustic
pressure is enough to cancel the force of gravity.

That is just ridiculous.
This is what it’s like to be a MEGA GEEK.
Saturday Morning Breakfast Cereal - Spacetime
Having just watched an episode of Through The Wormhole with Morgan Freeman regarding the subject of time-travel, I lol heartily at this strip.
This is so being set as my desktop wallpaper.

The Earth is a very small stage in a vast cosmic arena.
On it, everyone you love, everyone you know, everyone you ever heard of,
every human being who ever was, lived out their lives.
Thousands of confident religions, ideologies and economic doctrines,
every teacher of morals, every corrupt politician, every hero and coward,
every creator and destroyer of civilization,
every saint and sinner in the history of our species;
think of the rivers of blood spilled by all those generals and emperors so that,
in glory and triumph, they could become the momentary masters of a fraction of a dot.
Our posturings, our imagined self-importance,
the delusion that we have some privileged position in the Universe,
are challenged by this point of pale light.
It underscores our responsibility to preserve and cherish the Pale Blue Dot.

Deliciously awesome and geeky at the same time. This guy is awesome!
This is why we can’t have nice things.
Blue Rats!
The same blue food dye that gives your Gatorade its turquoise tint and turns your tongue a peculiar shade of purple might also protect your nerves in the case of spinal cord injury.
By lucky accident, researchers discovered that the commonly used food additive FD&C blue dye No. 1 is remarkably similar to a lab compound that blocks a key step in nerve inflammation. When rats with spinal cord injury were given an infusion of blue dye, they recovered much faster than rats that didn’t get the treatment. And researchers reported only one adverse effect: The rats turned blue.
