rtn. Wow ! I just watched this great, recent TED talk. Brenner is a physicist who lost a close friend to a bacterial infection. This inspired him to use his knowledge of physics to fight deadly bacteria in the environment. These bacteria are proliferating due to bacteria developing resistance by for example mutating. Brenner shows that a particular part of the electromagnetic spectrum can be used to kill most bacteria. The particular part of the spectrum is in the far ultraviolet portion of the spectrum. Light from this region have wavelengths that makes it not to penetrate the surface of human skin. It can however kill bacteria on the skin. Light with other frequencies around this region can penetrate the skin and induce cancer up to the deeper layers in the skin. Brenner and his team are working towards getting Food and Drug Administration approval in the USA for their fine tuned UV devices. I predict this technology will become omnipresent if approved. The works shows how physics can be used in diverse areas. #nit00a1science2physics3light #physics #everydayphysics #physicsisfun #science #everydayscience #medicine #health #light #uv #stem #homeschool #homeschooling #homeschoolmom #bacteria #epidemiology #ted #virology #pathology #education #entrepreneur
"Tesla’s Egg of Columbus: a copper ellipsoid egg (PhiTOP) mysteriously spins and stands upright in this modern version of Tesla’s famous demonstration from the 1893 World’s Fair in Chicago that first showcased the principles behind wireless power transfer and his AC induction motor. Rotating magnetic fields from under the wooden platform induce electric eddy currents to flow in the copper PhiTOP- these currents then create their own magnetic field which oppose the initial fields underneath and pushes the PhiTOP to spin. This version differs from Tesla’s in that the rotating magnetic fields are created by, well, a pair of rotating neodymium magnets (revealed by lifting the top platform in this model). Credit to astrophysicist Kenneth Brecher, the creator of the PhiTOP, and this unique means of using a common lab magnetic stirrer to create the induced currents. Finally, the ellipsoid top stands up vertically (when spun with sufficient rotational velocity) due to physics similar to that of the tippe-top. ➡️ Follow the link in my profile for info on where to get a PhiTOP and other amazing items featured here on @physicsfun Via @physicsfun Follow Me @physics_space.hq Don't forget to check out 👕on my profile with best 💲price, best quality
"Tornado Spheres: two ball bearings welded together can be made to spin up to 2000+ rpm by the Magnus Effect using a stream of air. Shining three colored LEDs on the spinning pair produces an illusion of floating rings along with a second illusion that these rings are rotating and changing direction due to aliasing with the frame rate of the video camera (like the famous wagon-wheel effect). ➡️ Follow the link in my profile for info on where to buy this and many other amazing items featured here on @physicsfun Via @physicsfun Follow Me @physics_funny.hq 👉🏽Click my profile too see the best shirt 👕!

"This rich starfield spans almost 10 degrees across the sky toward the northern constellations Cassiopeia and Perseus. On the left, heart-shaped cosmic cloud IC 1805 and IC 1848 are popularly known as the Heart and Soul nebulae. Easy to spot on the right are star clusters NGC 869 and NGC 884 also known as h and Chi Perseii, or just the Double Cluster. Heart and Soul, with their own embedded clusters of young stars a million or so years old, are each over 200 light-years across and 6 to 7 thousand light-years away. In fact, they are part of a large, active star forming complex sprawling along the Perseus spiral arm of our Milky Way Galaxy. The Double Cluster is located at about the same distance as the Heart and Soul nebulae. Separated by only a few hundred light-years, h and Chi Perseii are physically close together, and both clusters are estimated to be about 13 million years old. Their proximity and similar stellar ages suggest both clusters are likely a product of the same star-forming region. --- Credits: Adrien Klamerius Via @astro.physics Follow Me @physics_c00l If you like 👕Click to 🛒 my shop and get now!!!
"On the right, two, spiky, foreground Milky Way stars echo the trio galaxy hues, a reminder that stars in our own galaxy are like those in the distant island universes. With sweeping spiral arms and obscuring dust lanes, NGC 5566 is enormous, about 150,000 light-years across. Just above it lies small, blue NGC 5569. Near center, the third galaxy, NGC 5560, is multicolored and apparently stretched and distorted by its interaction with NGC 5566. The galaxy trio is also included in Halton Arp's 1966 Atlas of Peculiar Galaxies as Arp 286. Of course, such cosmic interactions are now appreciated as a common part of the evolution of galaxies. --- Credits: CHART32 Team --- Via @astro.physics Follow Me @physics_space.hq If you like 👕Click to 🛒 my shop and get now!!!

"What would it look like to return home from outside our galaxy? Although designed to answer greater questions, recent data from ESA's robotic Gaia mission is helping to provide a uniquely modern perspective on humanity's place in the universe. Gaia orbits the Sun near the Earth and resolves star's positions so precisely that it can determine a slight shift from its changing vantage point over the course of a year, a shift that is proportionately smaller for more distant stars -- and so determines distance. In the first sequence of the video, an illustration of the Milky Way is shown that soon resolves into a three-dimensional visualization of Gaia star data. A few notable stars are labelled with their common names, while others stars are labelled with numbers from Gaia's catalog. Eventually the viewer arrives at our home star Sol (the Sun), then resolving the reflective glow of its third planet: Earth. The featured video is based on just over 600,000 stars, but Gaia is on track to measure the parallax distances to over one billion stars over its planned five year mission. --- Credits: @NASA / Nick Risinger --- Via @astro.physics Follow Me @physics_fanclub 👉🏽Click my profile too see the best shirt 👕!

"Cloud Control. Clouds consist of tiny droplets of liquid water, small ice crystals or a mixture of the two. These droplets are about 0.02 mm (one thousandth of an inch) in size and form as a result of condensation of water vapor. Formation of droplets requires the presence of cloud condensation nuclei which are 0.0001 mm (one millionth of an inch) in size and can be composed of dust, soot, clay or even sea salt from the ocean. Cloud seeding encourages rainfall by artificially filling the air with condensation nuclei. Via @physicsinpictures Follow Me @physics_funny.hq If you like 👕Click to 🛒 my shop and get now!!!
