    Full text at http://howfarawayisit.com Until the 1900s, based on Young’s results, it was understood that light was a wave. And because waves were known to need a medium to propagate through (like water waves or sound through air), it was assumed that all space was filled with a massless substance that was given the name aether. Then in the mid-1800s, James Maxwell who was studying electricity and magnetism proposed that the existence of an electric charge filled empty space with an electric field. Here’s a NASA picture of small threads suspended in an oil aligned with the electric field of a charge. Accelerating the charge causes the electric field to change. Furthermore, he showed that a changing electric field created a magnetic field. And a changing magnetic field created an electric field. So the accelerated electron creates a disturbance in the electric field that propagates itself through space as an electromagnetic wave. Earlier, Michael Faraday and Andre Ampere had measured the resistance of empty space to the forming of an electric field called permittivity and the resistance of empty space to the forming of a magnetic field called permeability. Using these numbers, Maxwell calculated the speed of his wave and found that it was exactly the speed of light! He had discovered that light is an electromagnetic wave! There’s one more thing to point out about electromagnetic waves that will become important as we move inside atoms. Mathematically, waves can be described by a generalized wave equation that describes a vast number of different kinds of waves. For waves like this one, the solution to the wave equation provides valuable information about the wave’s characteristics, including its amplitude at any point in time. The idea of an aether filling otherwise empty space was rendered un-needed for light propagation once electromagnetic radiation was understood. So it faded from our vocabulary - replaced by the idea that empty space supported magnetic and electric fields and light represented a disturbance in the electric field. The exact characteristics of so called empty space will be a recurring subject for us as we approach our segment on the Higgs Boson.

        My first kinetic type piece and only the second thing I've produced using After Effects. Lots of room for improvement, but it was fun to learn and problem solve to achieve this. My main reference was the three-part kinetic type tutorial @ http://www.schoolofmotion.com/30dae/

                    In April 2014 These New Puritans hosted an interactive A/V installation in a beautiful Brutalist building in central London. Curated to explore the make up of a band whose work is widely lauded as amongst the most original and progressive of their generation, the exhibition centred around the 'Magnetic Resonator Piano' (MRP), an electronically-augmented acoustic piano which uses a series of magnets combined with sensors to resonate, bend and torment the piano's strings, creating infinite sustain, crescendos, harmonics, pitch bends and incredible new timbres. Visitors to the exhibition engaged with the MRP via motion-sensor technology, alongside other interactive exhibits enabling them to participate in the TNP sound, creating their own individual sonic experience via a series of triggers, loops, and samples. Special guests were also invited to experiment with this unique invention, resulting in spontaneous performances from avant-garde sound artists and Grammy winning producers to Westminster Abbey organists and experimental musicians. The MRP was used for the first time in popular music on TNP's album Field of Reeds. http://thesenewpuritans.com

                      It may offer the ultimate view of the human body- the MRI uses a magnetic field and radio wave pulses to make pictures of organs and structures; used to find problems such as tumors, bleeding, blood vessel diseases or infection. Getting the best images came at a cost. “Traditionally we had open MRIs and we have our closed MRIs. The closed MRIs are very claustrophobic but gave us the highest image quality and the best images. The open MRI was a much more patient-friendly environment but we couldn’t get very good images from it. And we’ve always had that problem,” says Dr. Cory Duffek, neuroradiologist with Lee Memorial Health System. Now its problem solved: the newest technology offers the high field magnet within an open setting. The images are high quality, with all the detail doctors are looking for. And the comfort is a pleaser for patients. Unlike an x-ray, which snaps a quick image, the MRI is time-consuming. Being in a closed tube for up to an hour can be unsettling for not only the claustrophobic, but children and people who are extremely overweight. “We have a table limit of 650 pounds, where in the past that was unheard of. So now we can accommodate and image people that have never been imaged before,” says Pete Kouba, MRI technologist with Lee Memorial Health System. Another patient population are those with back pain, this set up helps get them through testing. “We can add more pillows under their back; we can raise their head a little bit. If they can't lie on their back, they can lay on their side. And so we have much more options for patient positioning because we have more room to position the patient,” says Dr. Duffek. Being open to MRI is helping people get the treatment they deserve.
