Microscopic Images of Alcoholic Drinks All of these impressive photos of alcoholic beverages under a microscope uncover the elements that make up some of our preferred tipples. Similar to photos of snowflakes, each and every beverage is unique, while observed below when zoomed about 1, 000 times under a high tech lab microscope. Created by United States company Bevshots, these are available as artworks for potential buyers which recognize the concealed beauty of alcoholic beverages. Catching the small elements that define most popular drinks such as vodka, pina colada and Chablis. "What you can see in the magnified pictures are the crystalised carbohydrates that have become sugars and glucose, " described Lester Hutt, 35, the founder of Bevshots. He describes, "Each image was created by using a pipette of each particular drink and squeezing a drop onto a slide. Vodka and tonic Whiskey Vodka Tequila Sake Pina Colada Martini Dry Martini Champagne Red wine German Pilsner inevitable Coca Cola
Superposition of Waves The principle of superposition may be applied to waves whenever two (or more) waves travelling through the same medium at the same time. The waves pass through each other without being disturbed. The net displacement of the medium at any point in space or time, is simply the sum of the individual wave displacements. This is true of waves which are finite in length (wave pulses) or which are continuous sine waves. Constructive and Destructive Interference Two waves (with the same amplitude, frequency, and wavelength) are travelling in the same direction on a string. which is a travelling wave whose amplitude depends on the phase (phi). Two sine waves travelling in opposite directions create a standing wave A travelling wave moves from one place to another, whereas a standing wave appears to stand still, vibrating in place. This wave is no longer a travelling wave because the position and time dependence have been separated. Two sine waves with different frequencies: Beats
Watch this bead chain loop defy gravity and bend physics | Science! Science is unendingly cool because it can consistently confound the expectations of researcher and layman alike. Case in point, what do you figure would happen if you had a bead chain coiled up in a small container, then pulled one end out? You probably didn’t guess that it would leap up and uncoil like a tiny metallic snake, but that’s what happens. This demonstration is sometimes called Newton’s Beads. The effect seen above in slow motion is a function of momentum. It’s not a smooth arch like you might expect, even after coming to terms with the fact that it’s happening.
Watch ultra-light metal in action Students use giant balls to build omnidirectional motorcycle Riding this bike takes balls. Gigantic balls. Quite possibly the largest pair of balls you've ever seen in one place. Round wheels are out and spherical wheels are in with this project from students at San Jose State University, the end result of which will be a rideable electric motorcycle that uses balls instead of wheels. If this concept looks familiar, that's because you've seen it before. It's a little hard to see in the pic, but this Audi RSQ from I, Robot uses spherical wheels instead of round wheels. Outside of the movies, you may have also seen something like this as the drive system for a self-balancing, omnidirectional robot called Rezero: Essentially, this project is taking two of those ballbots, sticking them together, and adding some handlebars and a seat in the middle. Currently, the SJSU students have finished the bike's frame and have gotten themselves a pair of huge rubber-coated carbon fiber and fiberglass balls. Spherical Drive System Bike, via OhGizmo
