Superhydrophobic surfaces repel water. Both naturally occurring and manmade materials with this property share a common feature: micro- or nanoscale structures on their surface. Lotus and lily leaves are coated with tiny hairs, and synthetic coatings or micro-manufactured surfaces like the one in the video above can be made in the lab. This nanoscale roughness traps air between the surface and the water, preventing adhesion to the surface and enabling the water-repelling behavior we observe at the human scale. Although effective, these nanoscale structures are also extremely delicate, which makes widespread application of superhydrophobic coatings and textures difficult. (Video credit: G. Azimi et al.)

Newton’s third law says that forces come in equal and opposite pairs. This means that when air exerts lift on an airplane, the airplane also exerts a downward force on the air. This is clear in the image above, which shows a an A380 prototype launched through a wall of smoke. When the model passes, air is pushed downward. The finite size of the wings also generates dramatic wingtip vortices. The high pressure air on the underside of the wings tries to slip around the wingtip to the upper surface, where the local pressure is low. This generates the spiraling vortices, which can be a significant hazard to other nearby aircraft. They are also detrimental to the airplane’s lift because they reduce the downwash of air. Most commercial aircraft today mitigate these effects using winglets which weaken the vortices’ effects. (Image credit: Nat. Geo./BBC2)

That’s actually a theory incorporated into M-theory (string theory)
Sorry, I just used the word theory three times. 
Basically, there is a possibility, if string theory is correct and atoms are actually made up of tiny strings vibrating in 10 dimensions, we could have infinite parallel universes inside each and every quark contained in our body. We’re huge to them, and tiny to the universe WE are contained in. 
How bout that? There could be billions upon trillions of creatures, things, worlds, inside each atom inside us. Infinite universes in one quark. 
Mia your geek is showing.
This is why I study physics.

…whoah. brb, contemplating this forever.

So does that mean that when we die all those billions of universes and creatures die within us?


I knew I am a god
I fucking knew it


holy crap that is like world-ception

Dude what if stories and characters are real living in one of the many universes in the mind of the author. The author just happens to be in touch with them in someway.

WHAT

This is where our characters live.

these are my legit beliefs.

It turns out that exploding bubbles of hydrogen filmed at 16,000 frames per second are one of the coolest things on Earth. 

This is part of a study of the fluid dynamics of various explosive mixtures of hydrogen and air. The video talks a lot about the idea of “buoyancy”, which for flames and explosions relates to their ability to push out and displace the air around them, use up all the available fuel, etc.

Of course, if you’re not into the science side of it, just skip ahead in the video to about 1:20 and then pick your jaw up off the floor.

As per PhysicsPhysics recommendation, immediately stop what you are doing, and watch this video in 1080p in full screen. We promise you will have no regrets!

After extensive peer review, the Higgs Boson has finally become actual science.

CERN has not confirmed this is the Higgs Boson, but: 

"… as the Standard Model of particle physics only has one undiscovered particle remaining, it probably is the Higgs boson.”

There is also the outside chance of it NOT being the HB, so what happens then? How does a Higgs-less universe come about? Who knows?

All that means is we would have to come up with a new method of physics to explain how particles acquire mass.

One of my favorite little websites, Lists of Note, published this gem. It gives the “rest of us” a peek into the mind of a genius. He may have looked at his personal life in a similar way to his work.

New Cry3 Engine soft body physics gives realistic looking damage to objects. This is way cool!

The wave/particle duality of chickens. In Minecraft.

That is an awesome sentence.

And not just any mistake. A LOOSE CABLE. 

“There was a good reason the measurements and reality weren’t lining up: a loose fiber optic cable was causing one of the atomic clocks used to time the neutrinos’ flight to produce spurious results.”

oops

KNEW IT!

oh damn! there goes that neutrino-walks-into-a-bar joke…

:(

ahahahahahahahahahahahahaha xD
