of general relativity has to do with the way it defines inertial motion, i.e., the trajectories that free bodies would follow, which in the case of general relativity are timelike geodesics for bodies with non-zero mass and null geodesics for bodies with zero mass, such as photons. This...
When photons hit a solar cell, they knock electrons loose from their atoms. If conductors are attached to the positive and negative sides of a cell, it forms an electrical circuit. When electrons flow through such a circuit, they generate electricity. Multiple cells make up a solar panel, an...
This makes the phosphor atoms unstable, so they give off their excess energy as photons—which, this time, happen to be visible, white light (indicated here with yellow wiggly lines). Photo: The electronic circuit inside an energy-saving lamp. The transformer is the big orange/gold thing in...
While we don’t really want to go down the rabbit hole of technicalities as the team is rather far off from quantum physics, as far as we understand it, this is not just a better and faster way of computing – it has a fundamentally different basis. Just as with the candle and the ...
hehehehe I find it amusing that you take registration as a given... That is because Elf's data are all registered. Offering some service to my customers. :-) F.Meiresonne, imtl, Chaser of Photons and2 otherslike this #305 Guest
Javier De Elias Cantalapiedra from Madrid, Spain posted theYouTube videoabove to show his very elegant experiment in which he measured Planck’s constant using photons from a distant star. As in thee/m measurement he had previously shared with us, his experimental technique is very rigorous, whi...
We can either count the number of photons in a longer time interval (by a steady-state measurement of the fluorescence intensity) or make a time-resolved measurement of the fluorescence decay. These measurements can be done in an ensemble mode or on single molecules—the basic process is the...

based on a combination of the camera’s optics, image sensor design, firmware, engineering, and yes, its pixels — but not its megapixel count. At the heart of your camera is the image sensor, which contains the array of pixels. These pixels are like buckets that collect photons, or ...
