    I am a little concerned about a academic misconduct My name is Richard Kriske and I was the one who discovered this effect. I was the only person in history, with the exception of Einstein, that ever figured out that water has an ability to participate in the Photoelectric effect. Although I am thankful that these experimenters proved me right, they simply copied and renamed my theory. I should be nominated for a noble prize for this discovery and these researchers should come clean, and admit that they copied my work. Obviously the people at MIT also knew it was my work.

    There's this theory that systems ecologists like to share about the net effect of ecosystems being that they export entropy, which is conducive to biodiversity. However, if you ask them how exactly this works, you'll get vague references to blackbody radiation and the inherent difficulties of capturing free energy. I have my suspicions that there's more to it than basic thermodynamics. At least these discoveries seem to aid that theory with a hydrological analysis, pointing to the other theory that biogeochemical cycles all work "together" to produce this net effect. This makes me curious about something I often observe in the closed freshwater systems I study, and how with enough light intensity plants and algae will start accumulating bubbles on their surface. I always presumed this was a function of partial pressures and diffusion rates, but now that I think about it this even happens in turbulent systems with high flow rates and heavy oxygen sinking. I'm now starting to wonder if the light itself acts as a gradient force which causes water to evaporate at the plant's surface where the 02 concentration is high (gas saturated water), thus forcing nucleation. This would make more sense than partial pressures and diffusion rates alone being what explains it. Perhaps this even initially takes place inside of the cell, possibly helping to reduce intracellular O2 concentrations which would otherwise inhibit photosynthesis.

    A few years ago was wading in a small creek deep in a forest of Arkansas. I observed the plants and noticed their leaves being drawn down to the water, the roots were well within the source, even in the water in places...an odd tropism. It didn't make sense to me for the leaves being drawn down to the water when the roots were ample to water in these small trees, bushes and such. I prayed for wisdom and I considered things further, and on subsequent visits, I took rudimentary temperature and hydrometer measurements and found that where minimal sun's light was shining through the leaves near the water the temperature was substantially lower and the humidity was greater above the water where the light that was filtered through leaves. And then, I began to think about all the times, (living on the eastern edge of tornado ally) that when the sky turned green as often happens ahead of a tornado the temperature was drastically cooler than just a large cloud blocking the sun on a warm spring or summer day. It seemed that I was being shown that the color green was the causing the cooler more humid air in both scenarios. I did some( again rudimentary) experiments with a large magnetic suspended in green dyed water (using squeezings from cucumbers peels), in one of two identical glass pitchers. The other pitcher was the same setup as the other but with no dye in the water. I put the two pitchers in the freezer four hours. I took them both out into the sunlight and monitored the unfrozen area around the suspended magnet. In the green water pitcher the unfrozen water area around the magnet maintained its shape several seconds longer than the undyed water while in the midmorning sunlight.

    Green would complement plants as water is a by product that could be slowing down photo-chemical processes, thus by having a green surface the water to vapor rate being higher creates a larger gradient movement of water out of the process of photo-sysnthisis carbon bonding.

    @Muonium1 7 месяцев назад

    I do not think Dr. Chen is a crank, and I do believe he may be on to something interesting in his work, which does seem to me to be fairly careful and rigorous, but he really shouldn't start out these talks by saying "we all know water doesn't absorb visible light", *particularly when showing a photograph of very blue or blue-green water on his presentation slide while saying it* . The water literally by definition couldn't be blue if it "didn't absorb visible light". It DOES of course absorb visible light, and quite a lot of it at the red end of the spectrum owing to the tail end of the fourth overtone of the OH stretching mode of water molecules in the IR leaking down into the far red portion of the spectrum. We know this is true because heavy water really is colorless and doesn't absorb visible light since that OH absorption band along with its overtone is shifted further out to the infrared due to deuterium's larger mass.

    In the journal Optics Letters, researchers Glen A. Sanders and Austin Taranta from Honeywell and the Optoelectronics Research Center at the University of Southampton in the UK describe how they used a new type of hollow-core optical fiber. This allowed them to increase the stability requirements of the gyroscope by 500 times compared to other fiber optic gyroscopes. ❤With the help of the “HYBRID gyroscope” you can make scientific discoveries; in astronomy, astrophysics, cosmology, higher theoretical physics,... I am writing to you with a proposal for the joint invention of a HYBRID gyroscope from non-circular, TWO coils with a new type of optical fiber with a “hollow core photonic-substituted vacuum zone or (NANF)” where - the light travels 48000 meters in each arm, while it does not exceed the parameters 40/40/40 cm, and the weight is 4 kg. Manufacturers of “Fiber Optic Gyroscopes” can produce HYBRID gyroscopes for educational and practical use in schools and higher education institutions. Einstein dreamed of measuring the speed of a train, an airplane - through the Michelson-Morley experiment of 1881/2024, and only then would the experiment be more than 70% complete. This can be done using a fiber optic HYBRID gyroscope. Based on the completion of more than 70% of Michelson's experiment, the following postulates can be proven: Light is an ordered vibration of gravitational quanta, and dominant gravitational fields adjust the speed of light in a vacuum. (We are not looking for ether, we will see the work of gravitational quanta) The result is a «theory of everything» in a simple teaching device and a new tape measure for measuring the universe.

My HOD, ironically a Northwestern PhD, scolded me and then started obsessively following my social media activity. 6 months later, I am retired from academia and my HOD has been forced out by the Dean. By December 2023, I had become so fed up with my HOD's extremely unethical behavior that I opened up to the Dean in a lengthy whistle-blower letter. Ironically, I now make far more money working at a tech startup that may ultimately make use of the photomolecular effect. I don't miss the toxicity of academia at all!

    Have you considered the reflectivity of the surface your photons are interacting with? In water, photons approaching the surface can be reflected back down into the water, so if you are shining a beam at the surface, some of the photons reflect back. If there is collision with the reflected photons and the beam that could create enough energy to move electrons, breaking clusters off.

    Does the photomolecular effect hold for ammonia? It would be easier to detect temperature changes on this different hydrogen-bonded molecule. Would other headspace gases such as nitrogen or argon affect the photomolecular effect, versus air? What happens if a circularly polarized light is used instead of a linearly polarized light? May not be as interesting, since sunlight reflecting off a large body of water is linearly polarized. Does chlorophyll channel the light to keep the plant warm, promoting enzyme activity such as photosynthesis? Kudos to more fundamental research!

    Please make sure that the 532nm green laser output is monochromatic and does not contain any IR content. Most green laser pointers are made with a 1064nm IR pumping diode. This 1064nm infrared light is frequency doubled to produce output at 532nm. Although these make very nice green light some of these laser pointers have been reported to also output many times their output power in the invisible 1064nm infrared band.

Babies and Cats see B&W bees/butterflies see UV 🎉Which suggests colour is only perceived and identified as an effect of light temperature and interplay of different elements in subject and air, further the brain is the colour mixer... this makes me question then is green even green?

The subtractive primary colors are cyan, magenta and yellow, and you start with white and the more colors you mix the darker it gets until you have black. The additive primary colors are red, green and blue and you start with black, and the more colors you mix the lighter it gets until you have white.

    Near the end, he asks why plants choose to reject the most energetic part of the solar spectrum. Exactly the question I asked myself. Could it be that the green light is used mainly for transpiration? Without it, would vascular plants have even evolved?

    • @NanoNorthwesternUniv

      This is an excellent question and goes one step further than I was asking. Leaves reflectance to green light seems to be around 15-20%, a factor of two higher than red and violet. This also means not all green light is reflected and these photons getting into the materials can contribute to the transpiration via photomolecular effect. I do not know if people have studied plants transpiration under different colored light. It could be a very interesting research topic.

      Somebody mentioned on another video, and I agree with them, that water loss is a big risk for plants, and green could be where it peaks.

      Could the green light reflected at the surface make evaporative cooling during transpiration more efficient when in direct sunlight?

      @@NanoNorthwesternUnivTotally agree with your theory; biologically it’s likely the chloroplasts that do a lot of the absorption and imo the prevention of transpiration may be a dual purpose (i.e. using chloroplasts as essentially a heatsink for light energy; by utilising it in photosynthesis it would help mitigate transpiration losses potentially) This was an incredibly interesting presentation and I’m looking forward to the implications that come from it

      For evolution issue we need to think back billion years to origin of chloroplastic bacterial algae floating around in water column.
