Science News: Nanoguitar Photo by D. Carr and H. Craighead, Cornell. The world's smallest guitar is 10 micrometers long -- about the size of a single cell -- with six strings each about 50 nanometers, or 100 atoms, wide. Made by Cornell University researchers from crystalline silicon, it demonstrates a new technology for a new generation of electromechanical devices. The world's smallest guitar -- carved out of crystalline silicon and no larger than a single cell -- has been made at Cornell University to demonstrate a new technology that could have a variety of uses in fiber optics, displays, sensors and electronics. The "nanoguitar" -- made for fun to illustrate the technology -- is just one of several structures that Cornell researchers believe are the world's smallest silicon mechanical devices. "We have a new technology for building the smallest mechanical devices," said Harold G. The guitar has six strings, each string about 50 nanometers wide, the width of about 100 atoms. Photo by D.

DAD: Yes, I was in the shower. SARAH: Why? DAD: I was dirty. DAD: Why does the shower get me clean? SARAH: Yes. DAD: Because the water washes the dirt away when I use soap. DAD: Why do I use soap? DAD: Because the soap grabs the dirt and lets the water wash it off. DAD: Why does the soap grab the dirt? DAD: Because soap is a surfactant. DAD: Why is soap a surfactant? DAD: That is an EXCELLENT question. DAD: Why does soap form micelles? DAD: Soap molecules are long chains with a polar, hydrophilic head and a non-polar, hydrophobic tail. SARAH: Aidrofawwic DAD: And can you say ‘hydrophobic’? DAD: Excellent! DAD: Why does it mean that? DAD: It’s Greek! SARAH: Like a monster? DAD: You mean, like being afraid of a monster? DAD: A scary monster, sure. (pause) SARAH: (rolls her eyes) I thought we were talking about soap. DAD: We are talking about soap. (longish pause) DAD: Why do the molecules have a hydrophilic head and a hydrophobic tail? DAD: That’s complicated.

The clouds are updated daily with current weather satellite imagery. The Mercator projection used here is one way of looking at the spherical earth as a flat map. Used since the 16th century for navigation, straight lines on this map can be used accurately as compass bearings but the size and shape of continents are distorted. Compare this with Peters, Mollweide or equirectangular projection maps. Also available is a semi-realistic view of dawn and dusk from far above the Earth, a look at the moon, and information about how this works.
