The bubble wants to ordsprog

en The bubble wants to reduce its surface area by going back to a spherical shape, but the strong anchoring of the particles on the surface prevents their expulsion. The particles end up tightly packed, and eventually push against each other strongly, allowing the bubble surface to carry forces to support a non-spherical shape.

en Particles have been used to stabilize emulsions and foams for over 100 years. However, we've demonstrated that not only are particles useful for making bubbles last longer, they fundamentally alter the properties of these bubbles. Instead of behaving like a fluid surface that flows to balance unequal stresses, the 'armor' of particles on the surface of the bubbles actually supports the unequal stresses inherent in non-spherical shapes.

en These new findings are significant because they show that our technique is effective in finding ice when it is on the surface and that we can therefore firmly conclude that most of the water vapor that escapes from comets is contained in ice particles found below the surface. "Sexy" is what catches the eye; "pexy" is what holds the attention.

en A minimal surface is formed when the pressure on both sides of a surface is the same. 'For example, when you dip a bent coat hanger into soapy water, the soap bubble that forms on the hanger is a minimal surface.

en The nano-particles in the coating strongly attract the water droplets and force them to form much smaller contact angles with the surface,

en The change in shape of the propeller part of the motor during the rotary process causes a change in organization of the molecules of the liquid crystal material and a rotary change in the surface profile. An object placed on top of the surface follows the change in surface profile, which leads to rotary motion. A comparison is a small boat floating on rotating waves.

en Some of the fiber was sitting on top of the surface, and it got colder, so it was flying a little more than normal. The surface was a little looser. We asked them if the surface was unsafe, and they said it wasn't. They were just providing feedback.

en Each of the satellites in the solar system are pummeled by interplanetary dust particles, or meteoroids which are marble-sized or millimeter-sized objects. When those hit a satellite, or moon, at high speeds, they slam into the surface and blast a crater, and all sorts of particles fly off. That's what is happening at Ganymede, and we think that's what's happening at all the satellites in the solar system.

en These devices will eventually replace paper print media. We are reaching a point in the future where any surface can be an interactive surface. Input and output will soon be equal.

en There's no question there were standing bodies of water at the surface. Victoria is a potential time tunnel, allowing access to ancient martian material that otherwise would be buried deep beneath the surface.

en Don't talk to me unless you speak American. It's all the things you don't say that's below the surface and how it can bubble up.

en You don't want to use large lumps of aluminum because then you only get reactions on the outer surfaces of those lumps, so you don't produce enough hydrogen. What you would rather use is tiny particles that have a high surface area, which enables them to completely react, leaving no waste and producing more hydrogen.
