These 50 Photos From The Past Are Shocking And Hilarious. I Can't Believe How Things Have Changed... These photographers may have never known the significance of the pictures they took and that millions would be marveling at them in the future.
From thousands of images, I chose these to give us a rare and fascinating look at how different (and similar) life used to be. hyperallergic.com. Basic Triac and SCR Projects and Circuits. By Lewis Loflin This page will discuss basic triacs and SCRs.
A triac is a bidirectional, three-terminal dual, back-to-back Thyristor (SCR) switch. This device can switch the current in either direction by applying a small current of either polarity between the gate and one of the two main terminals. The triac is fabricated by integrating two thyristors in an inverse parallel connection. It is used in AC applications such as light dimming, motor-speed control, etc. 16 Awesome Car Modeling tutorials for 3ds Max. 1.

TPE sur le son : conversion de l'onde en signal électrique. 1) Structure générale L’oreille interne est composée de deux parties principales appelées respectivement labyrinthe osseux et labyrinthe membraneux.
Le labyrinthe osseux est une cavité creusée directement dans l’os temporal. Sa forme singulière est composée des canaux vestibulaires, sortes d’arcs impliqués dans la localisation dans l’espace, et de la cochlée, tube enroulé sur lui-même qui analyse et transmet les sons au cerveau. Ce labyrinthe osseux est rempli d’un fluide de couleur bleue nommé la périlymphe. Le labyrinthe membraneux est une enveloppe membraneuse, et donc souple, en suspension dans la périlymphe du labyrinthe osseux. 2) La cochlée Appelée également limaçon, elle s’apparente à une spirale enroulée sur elle-même. C’est également au niveau de la cochlée que le son est transformé en signal bioélectrique, et plus précisément dans le canal cochléaire, où se situe l’organe spiral ou organe de Corti, du nom de celui qui le décrit en premier, en 1851 : Alfonso Corti.
Untitled:Untitled - Cacoo. How to Make a Touch Screen. Black Hole Firewalls Confound Theoretical Physicists. From Simons Science News (find original story here).
Alice and Bob, beloved characters of various thought experiments in quantum mechanics, are at a crossroads. The adventurous, rather reckless Alice jumps into a very large black hole, leaving a presumably forlorn Bob outside the event horizon — a black hole’s point of no return, beyond which nothing, not even light, can escape.
Conventionally, physicists have assumed that if the black hole is large enough, Alice won’t notice anything unusual as she crosses the horizon. GravityLight: the low-cost lamp powered by sand and gravity. GravityLight … the lamp powered by sand and gravity.
Photograph: GravityLight The problem of bringing light to remote parts of the developing world has been tackled in the past with everything from solar-powered lamps to wind-up devices and rechargeable batteries – all of which require relatively expensive kit or physical effort by the user.

85+ Incredible Photoshop Image Manipulations That Will Leave You Awestruck. Photoshop, the image editing tool ever since it made its existence has actually grabbed the attention of many.
Some started using the tool just for fun while others took it seriously and planned to pursue their career and chose web designing. Now a days, indeed there are great number of ingenious people that let their creative juices flow and using this cool image editing software keep coming up with the marvelous pieces.With the ever developing technology, the web designers too have found the novel ways to show their creativity and express themselves in the artistic way. Photographers too use the tool to enhance the magnificence of the shots. SCIENCE HOBBYIST: My better stuff. Le héros fondateur. Notes L.
Transparency.jpg (Image JPEG, 2000x1200 pixels) - Redimensionnée (50%) TetraBox Light by Ed Chew. Liquid to Light Designer Ed Chew takes a green step in the right direction with the TetraBox lamp, a light object made from discarded drink packets that would have otherwise ended up in landfills already packed to the brim. The design is achieved by unfolding the packets and refolding them into hexagonal and pentagonal sections that are then pieced together to form a geodesic sphere or any other desired shape.
Here, the Epcot-like ball makes an attractive overhead light and casts an impressive web of shadows and shapes on the surrounding space. Cool gadgets for creative offices.

When you want to make a project small you might grab an Arduino Pro Mini instead of a full sized Arduino board but what if your project needs to fit into a blood vessel? F. Levent Degertekin, a professor in the School of Mechanical Engineering at the Georgia Institute of Technology is developing some miniature technology that will revolutionize how medical doctors will look at the heart and blood vessels.
Via: Electronics Lab “The device integrates ultrasound transducers with processing electronics on a single 1.4 millimeter silicon chip. On-chip processing of signals allows data from more than a hundred elements on the device to be transmitted using just 13 tiny cables, permitting it to easily travel through circuitous blood vessels. The dual-ring array includes 56 ultrasound transmit elements and 48 receive elements. Electrolux Design Lab 2012. Actinnovation.com. News - Robot Will Harvest Your Crops.
