Projects » Cohn-zone. Thermal photography. Thermal infrared cameras are designed to take photos or videos of heat (not to be confused with near infrared cameras).
Some of these are tuned specifically for gases, and can be used to image #methane. Applications Thermal imaging can be used to document heat/AC leaks from insulation gaps on a building's facade, reveal warmer ground water inflows (either fresh or chemical-laden) or "thermal pollution" from industrial processes entering ocean-temperature waterbodies, as well as identify areas on the human body experiencing infection or stress (includes epidemiological applications).
Specific models of FLIR brand cameras, known as the FLIR GasFinder ( See GasFinder below for more. Community applications so far include both a "heat-busters" program in East Harlem and a "forensic" water quality monitoring program in the Gowanus Canal. Questions DIY Approaches. Pranav Mistry.

Physics. Electromagnetic radiation. The electromagnetic waves that compose electromagnetic radiation can be imagined as a self-propagating transverse oscillating wave of electric and magnetic fields.
This diagram shows a plane linearly polarized EMR wave propagating from left to right. The electric field is in a vertical plane and the magnetic field in a horizontal plane. The two types of fields in EMR waves are always in phase with each other with a fixed ratio of electric to magnetic field intensity. Electromagnetic radiation (EM radiation or EMR) is a form of radiant energy, propagating through space via electromagnetic waves and/or particles called photons. In a vacuum, it propagates at a characteristic speed, the speed of light, normally in straight lines. In classical physics, EMR is considered to be produced when charged particles are accelerated by forces acting on them. Liquid Crystal Group Hamburg. General Relativity — Einstein Online. With the general theory of relativity, in which Einstein managed to reconcile relativity and gravitation, he had to discard the traditional physics worldview, which saw space as merely a stage on which the events of the world unfold.
SudoGlove Hardware Controller. Demoing the SudoGlove at the 2011 Open Hardware Summit What is the SudoGlove?
The SudoGlove is a gesture controller that can be easily interfaced with hardware or software via a wireless connection. The glove implements an array of sensors plus filtering circuitry and mathematical analysis firmware to derive state values for each sensor and transmits them to an authorized receiver. I have used the glove to drive an RC car, to synthesize music, to manipulate openGL video, to control arbitrary processing software, and to control performance lighting effects. You can see videos and examples of these interfaces below.

All action takes place around NASA’s Space Sciences Laboratories, UC Berkeley, to recordings of space scientists describing their discoveries. Actual VLF audio recordings control the evolution of the fields as they delve into our inaudible surroundings, revealing recurrent ‘whistlers’ produced by fleeting electrons . Are we observing a series of scientific experiments, the universe in flux, or a documentary of a fictional world?

An impressive homemade wall climbing system from a simple vacuum cleaner was created by a scientist from BBC.
After being bitten by a radioactive spider, the mild-mannered Peter Parker in the Spiderman movies and comics finds himself able to climb up the side of buildings. The enterprising scientist Jem Stansfield got the same effect in real life from the two vacuum cleaners purchased at Tesco. From the video below, he demonstrated his Spiderman Prowess by climbing up the 120 feet front wall of BBC Television center as he documented his experience. The image below shows how he used the suction power of a modified vacuum cleaner motor to hold his weight on the wall. His 170 pound body was easily held by the pads.
Aurora Detectors. Physics Solar Workshop. Solar power technology in action.
In one way or another, almost every form of energy we use originates as energy from the Sun. Solar energy directly powers photovoltaic cells and thermal collectors. Indirectly, we get power from plants grown by the Sun, oceans heated by the Sun, and Earths weather systems sustained by the Sun. Even the energy stored in fossil fuels originated as energy from the Sun, captured by plants and animals millions of years ago. Physics Solar Workshop explores the topic of solar energy, focusing on photovoltaic cells. Tekniska museet - Tekniska museet.
