What technique has helped engineers make airplanes safer? Hint: this technique can help us reveal small flaws in various materials long before we discover them. The answer is holography. The technique was first invented and developed by 1971 physics laureate Dennis Gabor. In the 1940s and 50s, Gabor discovered... a way of producing images with the illusion of depth. The method was based on interference – interaction between light waves – and coherence – light waves aligned in phase with one another. Light falling on an object is captured on photographic film along with a reference beam. When only the reference beam falls on the developed film, the light is bent so that a reproduction with depth is produced.

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.

You've never seen such a sight in your life. Scientists transformed ordinary mice into fierce predators using a technique called Optogenetics, where they control neurons with light (blue light here) When the light was OFF, the mice were calm, even avoiding prey But with the blue light ON? They aggressively attacked and even beheaded crickets & bit hard on toy prey. If a beam of blue light can switch aggression on and off in a mammal, Imagine what unfiltered blue light from your screens is doing to you.

How can we determine the age of an ancient artefact? ⁣ The answer lies in carbon-14 dating, a method developed by 1960 Nobel Prize laureate in physics Willard Libby.⁣ All living organisms continually renew their carbon-14 reserves, and when they die, the carbon-14 begins to decline at steady pace. ⁣ ⁣ Libby realised it was possible to determine the time of death by measuring these reserves in remains up to roughly 50,000 years old. His discovery revolutionised archaeology. ⁣ Carbon-14 dating is still used for revealing details about ancient ecosystems and helping improve our understanding of how human activity is affecting the planet.⁣ ⁣ This content was created as a co-production between Nobel Prize Outreach and the BBC.⁣

What do popcorn, wi-fi and the Big Bang have in common? The answer is microwaves. The 1909 physics laureate Guglielmo Marconi made a revolutionary telephone that used microwaves. The technology kept evolving during World War II. Some decades later, two other physics laureates made another microwave-related discovery. Arno Penzias and Robert Wilson – awarded the prize in 1978 – found the cosmic microwave background, an echo of the Big Bang that still fills the universe. In other words, microwaves play small and big roles in our lives as humans. Both when you pop popcorn as well as when you reflect on the origin of humanity as a whole.

Universities teach many erroneous models. One example of a misleading teaching is the Newtonian model of the prism. A man named Johann Goethe corrected and complimented Newton's model about 100 years after Newton. It is not the same light passing through the prism and distributing. It is a brand-new light with each beam of color. The primary light hitting the prism is extinguished by the electrons making up the glass of the prism itself. Those same electrons re-emit a brand new light from each angle. That process happens at the rate of c. Serving the illusion that the original white light came it... separated and exited to continue on. Most people rely on outdated text books or the Pink Floyd album cover "Dark Side of the Moon" to get their information about light and color and prisms. The depictions of light "splitting" and "bending" through a prism based on their color is false. (See first comments for attached images and substantiation) I filmed these videos playing around with prisms, lasers, magnifying glasses, mirrors, slits, and colored filters. I've gained my own perspectives on light and color over the years from real world, hands-on experimentation and observation. Most people have never held a real glass prism their own hands and done the tests to see for themselves. 2 prisms for $10 Harmonics of Light and Sound: This guy said his units were confiscated by the FBI and he was threatened not to pursue manufacturing them. The unit is simply a light with a magnifying glass and colored filters to isolate the light. Like burning an ant with a focal point... but with a specific color. The lens can spin and create a stroboscopic effect in an isolated band. The inventor claimed it healed stuff.

The impossibility of proving something through experiments. Laser and Mirror observation: It's never the same light. Re-emission Example: I put this interactive page together going back and forth with ChatGPT to code using Javascript. Here is a video playing with the slide controls to show 3 different sinewaves (3 different lights/emissions). The packets are ALWAYS in phase from medium to medium. The frequency shifts BECAUSE the velocity of light shifts. NOT a Doppler shift of "the same light" distorting within the same frame of reference. It's a brand new light at each point. The incoming light is a different frame of reference. All the light you ever see is the re-emitted light from the electrons making up yourself.

In 1887, Heinrich Hertz noticed that some light made it easier for electrons to escape a metal surface, but the pattern made no sense under Classical Physics. The surprise was that very bright red light could fail, while dim blue or ultraviolet light worked immediately. Einstein explained this in 1905 by proposing that light comes in energy packets, and only packets with enough energy can knock electrons free. That was the Photoelectric Effect, and it helped earn him the 1921 Nobel Prize in Physics.

In this video, as I was watching those few beautiful glimpses... I heard Sadhguru ask the volunteer her name. She said Jyoti... and instantly he asked with a playful smile, “Are you lighting it up?” That small exchange of laughter, smiles, and energy was beautiful. It felt like a reminder from life itself... The light in our lives is always asking... are you lighting it up? We can only give what we have. And the one who is lighting up millions of lives across the globe with his inner light is my Guru... Sadhguru. In the space between the Divine and the devotee, the boundaries melt. Who is Divine... who is the devotee... when the same light is shining in all?

THE CONTRASTING EFFECTS OF BLUE AND RED/NIR LIGHT ON THE MITOCHONDRIA. - Recent research published this year in Nature: Scientific Reports demonstrates the effects that light in the built environment has on human health. Our modern build environment is dominated by short-wavelength light from LEDs and fluorescent lighting. This can have deleterious effects on the mitochondria. Adding to this effect is the lack of long-wavelength light from sources like the sun and incandescent lighting bulbs. These long light wavelengths have a beneficial effect on mitochondria function and overall human health. The lack of them in our modern built environment, seems to be impacting public health in a delirious fashion. Two recent papers to read: 1. 2.

This is insane… 🚨 RFK JR says Dr. Anthony Fauci funded something called “The seamless ligation technique, aka the "no-see'm" method”, which was a Technique Designed to HIDE Evidence of Human Tampering with a Virus And he gave this technique to the Chinese Government. “What is the public health rationale for doing that?” The technique was developed by Dr. Ralph Baric at the University of North Carolina, and funded through the National Institute of Allergy and Infectious Diseases (NIAID). This “Seamless ligation technique” allows for the assembly of viral genomes or DNA fragments without leaving obvious genetic signatures of laboratory manipulation, which can make it difficult to distinguish between naturally occurring and lab-engineered organisms.

Fritz-Albert Popp was a German biophysicist and one of the godfathers of biophoton research. Dr. Popp published 8 books and over 150 scientific articles spanning theoretical physics, biophotonics, and medicine. In this interview, he makes the striking statement that biochemical reactions can ONLY take place when the molecule undergoing conversion is first stimulated by LIGHT. Virtually all metabolites in the body have absorption spectra. In other words, all metabolites absorb light within a range of wavelengths. For example, the amino acid tryptophan absorbs strongly at 280 nm (UVB light), while melanin absorbs ALL wavelengths of light (including radiowaves, X-rays, and gamma radiation). Some metabolites also have emission spectra, meaning that they not only absorb light but also release light. For example, tryptophan absorbs UVB light, and emits UVA light. Dr. Popp also makes the point that the photons produced by the body have high coherence. Another form of coherent light that everyone is familiar with is LASER light. All living systems produce coherent biophotons which actually facilitate metabolic reactions. Moreover, the ultimate source of ALL photons on the planet is the SUN! Biology uses sunlight to create coherent light on the inside that orchestrates metabolism. Every time you sit down with someone in the flesh, or spend time in Nature, with animals, plants, microbes etc. you are exchanging biophotonic information with your environment and those in it. The digital landscape is, and will forever be, a poor replacement for real life experience largely for this reason. ☣️ Pleb Kruse = BTC foundationalist in exile 🟩🔆 Nick Jikomes #biophotons #fritzalbertpopp #biophysics #light #sun #lightbiology #biology #medicine #health #metabolism

It is the year 1978, the Polish company Unitra CEMI makes its own microprocessors based on the production of its own silicon single crystals using the Czochralski method produced on machines built by itself. On this fragment of the film produced by great cameramen and editors you will see two devices manufactured by Unitra CEMI. Automatic wire bonder P536 and automatic tester of transistors and diodes M131A with automatic sorter. The Interlude with music is the MiG 21. For me, the sight of Polish inscriptions on control panels and nameplates in Polish on machines of this type is the reason why I have tears in my eyes. Beautiful film and beautiful devices from the time when we had a developed industry in Poland. Politics has fucked up everything.
