It’s been way too long since I’ve posted one of these. This is my portrait of Steven Sasson, inventor of the digital camera. He was the 32nd inventor in my project. I shot him in October at Kodak’s headquarters in Rochester, just a couple weeks before President Obama awarded him the National Medal of Technology . When he initially mentioned that the first digital camera held 30 pictures, I assumed that was due to the storage capacity of the digital tape. It was really interesting to hear that he picked 30 as an artificial limitation, and his explanation why.
When it comes to solar storms, there’s no longer any place to hide. For the first time, solar scientists have obtained simultaneous views of the entire sun, both the front and back sides. <img class="size-full wp-image-11123 alignright" title="sciencenews" src="http://www.wired.com/images_blogs/wiredscience/2009/09/sciencenews.gif" alt="sciencenews" width="200" height="40" />

World's smallest silicon mechanical devices are made at Cornell Smallest guitar, about the size of a human blood cell, illustrates new technology for nano-sized electromechanical devices FOR RELEASE: July 22, 1997 Contact: Larry Bernard Office: (607) 255-3651 E-Mail: email@example.com 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.
Posted by kobaxe on ShareThis Share 201 Here are few spectacular images of the corona, the outer magnetic field of sun, which is in the form of a shell of super-hot gas. It is hard to imagine a temperature of around 2,000,000c in general and much harder to see it due to unbearable brightness. But, the eclipse hunter Miloslav Druckmuller provided these stunning images which he took on the Marshall Islands in July 2009. The image is a montage and is a combination of 38 images taken at the spot with exposure time between 1/125 seconds and 8 seconds. I am sure that these images will mesmerize you for a while.
The deepest ocean on Earth is the Pacific Ocean's Marianas Trench, which reaches a depth of 6.8 miles awesomely trumped by the depth of the ocean on the Jupiter's moon, Europa, which some measurements put at 62 miles. That's deep! Although Europa is covered in a thick crust of scarred and cross-hatched ice, measurements made by NASA's Galileo spacecraft and other probes strongly suggest that a liquid ocean lies beneath that surface.
Many describe the double-slit experiment in a more mysterious way, that necessary. Especially, when they talking about an "observer": "Just mere observation changes behavior of electrons", "Electron chooses behavior when observed". The method of "observation" almost never described, but somehow assumed principally different from registration of electrons on, for example, the TV picture tube.
The universe can be a very strange place. While groundbreaking ideas such as quantum theory, relativity and even the Earth going around the Sun might be commonly accepted now, science still continues to show that the universe contains things you might find it difficult to believe, and even more difficult to get your head around. Theoretically, the lowest temperature that can be achieved is absolute zero, exactly ?273.15°C, where the motion of all particles stops completely. However, you can never actually cool something to this temperature because, in quantum mechanics, every particle has a minimum energy, called “zero-point energy,” which you cannot get below.
The Elegant Universe: Part 3
By Duncan Geere, Wired UK The last time a wet dog looked Andrew Dickerson in the eye, readying a shake, he didn’t flee in terror like most people would. Instead, like any true physicist, he whipped out a slow-motion video camera to see if he could capture the exact frequency at which its body was oscillating. Dickerson, along with some colleagues from the Georgia Institute of Technology, has written “ The Wet-Dog Shake ,” published in Fluid Dynamics . They attempt to calculate the optimum speed at which dogs should shake to most efficiently dry their fur.
