“The prediction was that we would get a dozen particles larger than human hair size and one particle a little bit larger than a millimeter.”
Donald Brownlee
“For everything exists and not one sigh nor smile nor tear, one hair nor particle of dust, not one can pass away.”
William Blake
“This is so tiny it can go where no one has ever gone before. (Nano-particles) can cross the blood-brain barrier. The general concern is that the safety work really has to be done or people won't trust the products.”
Nigel Cameron
“When dust is smaller than or comparable to the wavelength of light, the reflected color is dominated by particle size effects rather than the intrinsic color of the material.”
Imke de Pater
“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.”
Douglas Hamilton
“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.”
“If the particles are one micron (wide, or one-millionth of a meter), they'll make a track that is about 100 microns long.”
