Two crossed polarizers block all light. Add a 45° filter between them, and light suddenly slips through! Why? The middle filter acts as a quantum measurement device, forcing photons to "re-prepare" their state and rotate their vector to pass the final block.

SCIENTISTS TURN LIGHT INTO A MEMORY SYSTEM Scientists built a tiny photonic chip and sent identical photons through it, expecting messy quantum behavior. Instead, the light started acting like a memory system, forming patterns that match a classic AI model used for associative memory. In simple terms, the interference between photons did the math needed to store and recall patterns. No brain, no computer, just light physics doing the computing. Source: NewsForce

Why do so many ancient traditions describe enlightenment as becoming light? Why does the ore need to turn into gold for the alchemical process to be complete? Is the body of light the fourth state of matter—plasma? A body made of light? Moses, Jesus, Buddha, Krishna, and Zoroaster—their halos all signify a body made of light.

Quantum field theory predicts that light can scatter off light, an effect beyond classical electrodynamics. Maxwells equations are linear such that two photons never interact with each other However, in reality, if you cross two light beams photons will scatter if they're energetic enough. Even in vacuum, the photons interact with the ever-present quantum fields of charged particles, like electrons, even when no actual charged particles are present But you need very high energies to see this. Thankfully we built a machine specifically to probe nature at very high energies. At the LHC, this rare process of light-by-light scattering has been observed Hidden among millions of photons lighting up the detector, physicists were able to identify 26 distinct light-by-light scattering events This CMS graphic shows how they found them:

Leftoid goblins are now harassing the Coast Guard and calling them “Nazis” for not letting them block their base entrance. They came back last night and tried to ram a U-HAUL truck through the gate, forcing the Coast Guard to open fire. Arrest every one of these terrorists.

🚨UPDATE: Vibrant tiktoker Luwi Light has been abducted by state thugs. The state approached various tiktokers with huge following with the aim of buying them off in order to you use their platforms to campaign for the dictator. Luwi Light is one of the few tiktokers who refused this nonsense. Luwi Light is a mother to someone and a wife to someone and also someone's daughter. The culture of abducting citizens is unpalatable and deserves indictment by all Ugandans of good will. Luwi Light joins a long list of Ugandans who have been abducted due to their political beliefs. #FreeLuwiLight

Thomas Young's double-slit experiment, performed in 1801, is one of the most important demonstrations in physics. It provided strong evidence that light behaves as a wave by producing interference patterns. In the experiment, coherent light is directed at an opaque barrier with two closely spaced slits. The light waves passing through these slits interfere with one another, creating a pattern of bright and dark fringes on a screen positioned behind the slits. The spacing and location of these fringes depend on the light's wavelength, the distance between the two slits, and the distance to the screen. This experiment established the wave nature of light. The modern understanding of wave-particle duality, where light can also behave like particles (photons), developed in the early 20th century with quantum mechanics, and is beautifully illustrated by modern versions of the double-slit experiment performed with individual photons.

🚨 WOMAN PANICS AFTER AIR FILTER BEGINS HUMMING WHEN FLASHLIGHT HITS IT A woman records a strange moment inside her home after noticing that a dirty air filter begins emitting a low humming sound whenever a flashlight is aimed directly at it. As soon as the light is removed, the sound immediately stops. "Why is the dirty filter doing that?" To rule out coincidence, she swaps the dirty filter with a clean one, uses the same flashlight, and points it at the same spot under the same conditions. This time, nothing happens - no vibration, no hum, no sound at all. The effect only occurs with the dirty filter, and there are no visible electronics, speakers, or obvious power sources shown in the video. Confused by what she’s hearing, she eventually removes the filter from the house altogether. The clip has left viewers debating whether this can be explained by static electricity, vibration, airflow, or something else entirely - especially since the clean filter shows no reaction whatsoever. So what’s actually causing a household air filter to react to light like this?
