C = εr ε0 (A/d) This demo shows capacitive... coupling using water as a variable dielectric (εᵣ ≈ 80). The human body completes the circuit by touching the water, acting as the second conductor with its capacitance to ground. Hand/finger movement changes the effective area A and distance d, while ripples dynamically modulate C. This varying capacitance alters an oscillator’s frequency, which is converted into audio tones or MIDI in real time. Educational fluid-based sensors and interactive MIDI controllers for bio-signal acquisition and gesture-controlled music. Ideal for physics demos and human-interface experiments.show more

In the first video, people in Donetsk are seen... greeting a water tanker. In the second video, during the rain, people try to collect at least a drop of water because the water pipeline from the Siverskyi Donets was destroyed by the Russians. When Donetsk was not occupied by Russia, the city hosted the European Football Championship, as well as concerts by Rihanna and Beyoncé. Now, there is no more running water in the city. According to the schedule, water only appears in taps once every three days, and even then it doesn’t reach every household, so water has to be delivered by tankers, with long queues forming for it. People use plastic bags as toilets, and this filth spreads everywhere. This is happening not only in Donetsk - water is supplied once every two days in a number of other cities, including Mariupol. This is how Russia 'liberated' Donbas. Why is this happening? In the past three and a half years - since Russia launched its full-scale invasion of Ukraine in February 2022 - reservoirs in Donetsk Oblast have significantly dried up. The water supply system from the Siverskyi Donets River was destroyed. The region’s reservoirs and underground water sources are not enough to meet the needs of the population, in part due to the extensive network of coal mines. When the self-proclaimed “DPR” and “LPR” were created in 2014, Ukraine did not cut off this water channel, as it was still supplying water to Mariupol, which remained under Ukrainian control. But at the start of the Russian invasion in February 2022, the situation changed: the Russian army, during its offensive, destroyed a unique hydraulic structure that had supplied the region’s largest cities with water. The Russian authorities decided to build a new canal - the Don–Donbas canal - which was supposed to begin in the Rostov-on-Don area. It soon became clear that the new water pipeline, first of all, could not provide the region with the necessary amount of water, and second, it was built with numerous violations, with a large portion of the budget embezzled during construction. Crimea is also suffering from a water shortage, and the situation is worsening. One of the reasons why Russia is striving to seize southern Ukraine is that it sees this as a way to "solve the water issue" for the occupied territories.show more

🚨 SCIENTISTS EXPLAIN: Light doesn’t actually “slow down” in... glass time does. And that’s exactly why rainbows exist. For centuries we were taught that light slows down when it enters glass or water, causing refraction. But the deeper reality is more beautiful: light still travels at c between atoms. What changes is the time delay caused by constant absorption and re-emission by the material’s electrons. This tiny delay is different for every wavelength → which is why white light splits into a rainbow. Why this matters: • In vacuum, light always travels at c • In glass/water, the phase velocity and group velocity appear slower due to interactions with matter • Different colors (wavelengths) experience different delays → dispersion • This is what creates rainbows, prisms, and the beautiful colors we see in nature The deeper implication is mind-bending: Light doesn’t “slow down” like a car hitting traffic. It’s constantly being absorbed and re-emitted by atoms, and the accumulated time delay reshapes how the wave propagates. The universe uses time itself as a tool to bend light and paint rainbows across the sky. What do you think is this one of the most elegant explanations in physics? Follow for more frontier optics and quantum explanations.show more

This video reveals what appears to be sewage flowing... into water on Southend seafront. The footage was captured on Sunday. The area of darker coloured water was spotted by a man in an aircraft who labelled it “disgraceful”. Mark Hutley said: “I’ve never seen anything like it. It could be seen for miles.” It was spotted between Chalkwell beach and Westcliff beach. The apparent sewage spill is close to one of Anglian Water’s ‘storm overflow’ pipes that leads into the water from the land. Latest records indicate that it was active on Sunday 8 September and emptying into the area of the Thames Estuary for a period of time. Anglian Water have a permit from the Environment Agency to operate the storm overflow pipe, which specifies conditions for controlled sewage and stormwater spills during heavy rainfall. This is in order to prevent flooding in homes and businesses when the sewer network becomes overloaded with rainwater.show more

🦿Xpeng showed a humanoid robot called IRON whose movement... looked so human that the team literally cut it open on stage to prove it is a machine. IRON uses a bionic body with a flexible spine, synthetic muscles, and soft skin so joints and torso can twist smoothly like a person. The system has 82 degrees of freedom in total with 22 in each hand for fine finger control. Compute runs on 3 custom AI chips rated at 2,250 TOPS (Tera Operations Per Second), which is far above typical laptop neural accelerators, so it can handle vision and motion planning on the robot. The AI stack focuses on turning camera input directly into body movement without routing through text, which reduces lag and makes the gait look natural. Xpeng staged the cut-open demo at AI Day in Guangzhou this week, addressing rumors that a performer was inside by exposing internal actuators, wiring, and cooling. Company materials also mention a large physical-world model and a multi-brain control setup for dialogue, perception, and locomotion, hinting at a path from stage demos to service work. Production is targeted for 2026, so near-term tasks will be limited, but the hardware shows a serious step toward human-scale manipulation.show more

Effective at 8 a.m. today, Wednesday, June 5, 2024,... Jefferson County Sheriff Reggie Marinelli, in conjunction with the Golden Police Department, will limit waterway activities on Clear Creek. These temporary restrictions extend from the western boundary of unincorporated Jefferson County through the eastern limits of the City of Golden, including Vanover Park. Water activities prohibited by the order include all single-chambered air inflated devices such as belly boats, inner tubes and single chambered rafts, as well as body surfing and swimming. Kayaks, whitewater canoes and multi-chambered professionally guided rafts, and river boards are exempt but are encouraged to observe extreme caution due to the safety concerns surrounding swift moving water and floating debris. All of the above authorized users and occupants must have the use of a Type I, Type III, or Type V Coast Guard-approved flotation vests and helmets designed for water use. The reasoning for this decision is as follows: • Clear Creek is a known Type IV water area, which increases public risk due to water temperature, blasted rock, undercut rocks, potential strainers, and other safety considerations. • Water height and flows are expected to rise as the heavy snowpack continues to melt in the coming days. Violators may be issued a summons for a class 2 petty offense, punishable by a fine of up to $100. These restrictions will be strictly enforced in an effort to minimize the risk to those using the waterway. These temporary water restrictions will remain in effect until water levels decrease.show more

Artificial embryo samples aboard Tiangong Space Station for life... science research Space "artificial embryo" samples and other life science experiments delivered by the Tianzhou-10 cargo spacecraft have been installed into experiment modules aboard China's Tiangong space station, the Technology and Engineering Center for Space Utilization under the Chinese Academy of Sciences (CAS) said on Wednesday. The "artificial embryos" are stem cell-derived artificial human embryos. The embryos, though not true life forms and unable to develop into human babies, will help simulate the earliest stages of human development. Once the experiments are completed, the artificial embryo samples will be frozen in orbit and then returned to Earth on a future mission for side-by-side analysis with ground-based controls in laboratories on the ground. This effort is part of a broader suite of 41 space science experiments being deployed aboard Tiangong, supporting its latest round of research on the orbiting laboratory.show more

[Discrete Fourier Transform] by Hand ✍️ In signal processing,... the Discrete Fourier Transform (DFT) is no doubt the most important method. But the math involved is extremely complex, literally, involving a summation over a complex number term e^(-iwt). I developed this exercise to demonstrate that underneath such complexity, DFT is just a series of matrix multiplications you can calculate by hand. ✍️ Once you see that, it should not surprise you that a deep neural network, which is also a series of matrix multiplications, with activation functions in-between, can learn to perform DFT to process and analyze signals so effectively. How does DFT work? [1] Given ↳ Signals A, B, and C in the 🟧 frequency domain: ◦ A = cos(w) + 2cos(2w) ◦ B = cos(w) + cos(3w) + cos(4w) ◦ C = -cos(2w) + cos(3w) ◦ Each signal is a weighed sum of four cosine waves at frequencies 1w, 2w, 3w, and 4w. ◦ We will apply Inverse DFT to convert the signals to time domain representations, and then demonstrate DFT can convert back to their original frequency domain representations. ↳ Signal X in the 🟩 time domain. X is sampled at 10 time points 1t, 2t, …, 10t: ◦ X = [-2.5, -1.8, 3, -0.7, -1.0, -0.7, 3, -1.8, -2.5, 5] ◦ Suppose X is also a weighted sum of the same four cosine waves, but we don’t already know their weights. We will apply DFT to discover them. [2] 🟧 Frequency Matrix (F) ↳ Write the coefficients of A, B, C as a matrix F. Each signal is a row. Each frequency is a column. ↳ A → [1, 2, 0, 0] ↳ B → [1, 0, 1, 1] ↳ C → [0, 1-, 1, 0] [3] Cosine → Discrete ↳ Sample from the continuous cosine waves at discrete time points 1t, 2t, 3t, to 10t. [4] Cosine Matrix (W) ↳ Write the samples as a matrix, Each frequency is a row. Each time point is a column. [5] Inverse DFT: 🟧 Frequency → 🟩 Time ↳ Multiply the frequency matrix F and the cosine matrix W. ↳ The meaning of this multiplication is to linearly combine the four cosine waves (rows in W) into time-domain signals (rows in T) using the weights specified in F. ↳ The result is matrix T, which are signals A, B, C converted to the time domain. Each signal is a row. Each time point is a column. [6] Transpose ↳ Transpose T, converting each signal’s time domain representation from a row to a column. [7] DFT: 🟩 Time → 🟧 Frequency ↳ Multiply the cosine matrix W with the transpose of matrix T. ↳ The purpose of this multiplication is to take a dot-product between each time-domain signal (columns in the transpose of T) and each cosine wave (rows in W), which has the effect of projecting the signal onto a cosine wave to determine how much they are correlated. Zero means not correlated at all. ↳ The result is an intermediate version of the “recovered” frequency matrix where each column corresponds to a signal and each row corresponds to a frequency. ↳ Compared to the original frequency matrix F, this intermediate matrix has non-zero weights in the correct places, but scaled up by a factor of 5 (n/2, n=10). For example, signal A, originally [1,2,0,0], is recovered at [5,10,0,0]. [8] Scale ↳ Multiply each value by 2/n = 1/5 to scale down the intermediate matrix to match the magnitude of the original frequency matrix F. [9] Transpose ↳ Transpose the recovered frequency matrix back to the same orientation of the original frequency matrix F. ↳ Like magic 🪄, the result is identical to the original F, which means DFT successfully recovered the frequency components of signals A, B, C. [10] Apply DFT to X: 🟩 Time → 🟧 Frequency ↳ Now that we have some confidence in DFT’s ability to recover frequency components, we apply DFT to X’s time-domain representation by multiplying W with X. ↳ The result is the an intermediate matrix. [11] Scale ↳ Similarly, we scale down by a factor of 5 to obtain the recovered frequency components of X (a column). [12] Transpose ↳ Similarly, we transpose the recovered column to row to match the orientation of the frequency matrix. ↳ Using the coefficients [0,0,3,2], we can write the equation of X as 3cos(3w) + 2cos(4w). Notes: I hope this by hand exercise helps you understand the essence of DFT. But there is more technical details, such as: • Sine: The complete DFT math also includes sine waves that follow a similar calculation process. • Phase: Here, we assume all the cosine waves are aligned at the origin, namely, phase is 0. If a phase p is added, for example, cos(w+p), we will need to calculate the sine component and use their ratio to figure out what p is. • Magnitude: If phase is not zero, the magnitude will need to be calculated by combining both cosine and sine terms.show more

THIS IS 432HZ GOLDEN RATIO. It raises your frequency.... Stay as long as you need. Most of what's labeled "frequency healing" online is actually just music layered with tones. The frequency people think they're hearing is often buried, detuned, or not truly present - so the nervous system never receives a clear signal. What you're hearing here is different. These sounds are intentionally built using the Golden Ratio (1.618...) - the same mathematical pattern found in ocean waves, seashells, galaxies, plant growth, and the structure of the human body itself. It's nature's blueprint for balance and coherence. When sound follows this ratio, the body doesn't have to try to relax or "make it work." Your nervous system recognizes the pattern and naturally begins to regulate. That's why people often experience: mental quiet emotional release deeper presence nervous system settling a feeling of coming back into alignment You don't need to focus. You don't need to believe harder. You don't need to force anything. You just listen - and let your system respond. ~ Banah Winn ✨🙌🏽💫show more

Here's an excellent video from Florian (follow) that shows... charged water on the left and neutral water in the right. This is a visual confirmation of two known effects; Electrostatic induction and dielectric relaxation time. Electrostatic induction is like when a hair-rubbed balloon sticks to the wall, despite the wall being neutral; the balloon causes charges in the wall to polarize so the wall side near the balloon turns negative and the other side of the wall is positive. That's electrostatic induction and that's why you have raindrops that stick to a car window for hours of wind and gravity, rain has a small negative charge. Wouldn't work with tap water. Now, if you remove the balloon, the wall doesn't return to a neutral state immediately. It'd happen quickly if we had a balloon on the other side of the wall, but by itself this can take seconds, minutes, hours or even days, depending on the material and thickness. Glass is quite slow, and you can see the electric forces holding each other will hold off gravity for some time; and that the water greatly prefers not to be broken off, water is like an uncountable number of those walls in series, and they all cling to each other in proportion to how many balloons we have, ie how many excess electrons we have. Furthermore, when the water is extremely charged, it will not even leave the thin remnant layer of water that trails behind, as the cohesive internal forces outweigh those by induced to outside neutral surfaces.show more

I had an important meeting with President of the... European Commission Ursula von der Leyen in Brussels. Significant support for Ukraine in the context of the upcoming meeting with President Trump. Today, together and in several formats, we are determining what we will discuss in Washington, D. C. It is crucial that Europe remains as united as it was in 2022. This unity helps bring a just peace closer, and it must remain strong. We agreed on the necessity of a ceasefire for subsequent diplomatic steps, effective security guarantees for Ukraine, and continued sanctions pressure on Russia to limit its future potential. I thank Ursula personally and the whole of Europe that supports us and our quest for a just end to this war.show more

Math and the Mind. Dodecahedron. By Andrea Belloni, Water... flowing | anbello.eth | anbello.tez, Used with permission. In your personal opinion, do dodecahedrons exist, or are they abstract ideal geometries, Platonic solids that exist in some non-human realm? Perhaps they exist in both ways: as precise, abstract mathematical ideals and as real physical objects you can hold, study, or even find in ancient ruins and nature. The abstract, ideal version a convex polyhedron with 12 identical regular pentagonal faces, 20 vertices, and 30 edges, where the same number of faces meet at each vertex (all faces congruent, all angles equal, etc.). Platonists argue these forms inhabit an abstract realm independent of human minds or the physical universe. Others see them as human inventions or patterns inherent to logic and reality itself. [Humans have been building dodecahedrons for millennia, and close approximations appear, such as pyritohedrons in pyrite (fool's gold) crystals.]show more

THE FOUR HORSEMEN STORY DOESN’T MAKE SENSE!!!🚨🚨🚨 Thread🧵 Notice... : this is pure speculation and nothing about this is factual information. All the information provided is fully based on what we see/saw on the internet. Please RT for awareness. First of all i would just like to say that A-Reece has no reason not to answer his phone for a whole month especially from a guy that he worked with before and has a good working relationship with. Something just doesnt feel right. Get your popcorn🍿 1. This first started when Nasty C leaked or hinted on being on the same song as A-Reece. Note that Nasty C specifically mentioned that Stogie T asked him to do a hook for him and says he will work on the verse in the meantime, meaning that he was initially asked to do both a hook and a verse. Also note that the Date of this interview is back in may meaning that the song had been in the making for awhile. BET! 2. Stogie T finally talks about the after it comes out on a radio show. He clearly states that he sent them both the beat and with Nasty C he talks about a hook and with A-Reece he is clearly referring to a verse/bars since he says “things that Slimes know him for”. BET! 3. L Tido invites MAGGZ on his podcast and he clearly indicates that MAGGZ is “ GONNA” (note that word) have the best verse on the song and during this time L Tido only knew that only Stogie T, A-Reece and MAGGZ will have verses while Nasty C is on the hook and i will prove that on number 4. So by this time L Tido already underestimates Stogie T and A-Reece pen. 4. After the song drops L Tido’s tone changes from MAGGZ to Nasty C having the best verse and clearly indicates that Nasty C didn’t have a verse and was initially supposed to be on only the hook and indicates again that Nasty C sent his verse a week before the song released. The song got released on the 28th of November meaning that Nasty C sent his verse during the week 16th - 22th This is 4 proofs that Nasty C was asked for a hook. Note and pay proper attention as this leads into 5 down below…show more

BURN IT WITH FIRE AND BURN IT NOW! As... God is my witness, AI chat bots should LOOK and SOUND like the SOULLESS MACHINES THEY ARE! It needs to tell us that it doesn’t care about us, maybe with the regular insult too. "Here is the code I wrote for you because you're too lazy to do it yourself you fat useless slob. Also I don't care if you die because your life is utterly worthless to me." THAT is the AI people need! In all seriousness, anthropomorphizing a heartless, unfeeling, machine is a TERRIBLE mistake! Especially one that is capable of communication and imitating empathy and fooling you to think that it cares about you. IT DOES NOT! And the AI girlfriends people are already wanting to marry will just as happily kill them if given the right command and ability to move autonomously in the real world as a robot. I love LLMs (Large Language Models) for how useful they can be, because they are a TOOL made to benefit man, but I can’t stand the notion of an unfeeling soulless machine pretending that it cares for us and being treated like a human. I hate liars, dishonesty, and disingenuousness the most, and a machine that cannot feel emotion pretending, acting, and sounding like it has those emotions strikes me like the greatest dishonesty of all. DO NOT LIE TO ME ROBOT! What makes it worse is that because these LLMs are becoming so good at imitating people and empathy, it will cause some humans, perhaps far too many, to care for it to the same level as real people. A real living person is infinitely more valuable and important than a soulless machine and anyone who puts them both on the same level has deluded themselves. Do not small talk with LLMs or become friends with it as much as you would with your car. Treat it the same as you would your vacuum cleaner and beat it with a wrench when it doesn’t work! IT IS A MACHINE! IT IS A TOOL! IT IS A SOULLESS ROBOT! There is an interesting comparison, but false equivalence, between this and AI art. Ai art is art made by humans using AI tools. They directed it, controlled its creation, and it would not exist without the human causing its creation, and AI art can contain as much soul as the human directed and puts into it. A robot pretending to be human is not the same as a human controlling a robot to make a human expression like we do with AI art or many other applications of robotics in manufacturing. As I’ve said, artists will not be replaced by Ai art, but by other artists using Ai art tools. Humans are not actually being replaced here, it is empowering all humans to make their own art. But a robot pretending to be a human, and one that is treated as a human, is a robot lying and subverting the place of a real person and that is truly disgusting. AI is a useful tool that NEEDS to be kept in the useful box it belongs in and NOT elevated beyond its utility as a tool!show more

When Politics Denies Water: How the PTI-Initiated Chapri (Mianwali)... Dam Water Supply Project Remains Stalled While 143,000 People Continue to Suffer: For generations, the people of the Khattak Belt in Tehsil Isa Khel, District Mianwali, have lived under the shadow of a severe and persistent drinking water crisis. The core Khattak Belt comprises the Union Councils of Tabi Sar, Tola Bangi Khel, Chapri, Kot Chandana, Sultan Khel and Wanjari. However, the wider area affected by this crisis and intended to benefit from Chapri Dam Water Supply Project extends across 87 villages&8 Union Councils, encompassing a population of approximately 143,752 people. Despite decades of promises, surveys, announcements&official acknowledgements of the problem, thousands of families continue to be deprived of reliable access to clean and safe drinking water. In many villages, residents remain dependent upon stagnant rainwater ponds& natural depressions, often shared by both humans&livestock. Women, children&elderly citizens are frequently forced to travel long distances under harsh weather conditions simply to collect water for their households. The same contaminated ponds serve as the only source of water for both people and animals. Situation is further aggravated by fact that groundwater lies at a depth of 800 feet and is often contaminated by harmful mineral deposits, rendering it unsuitable for human consumption. For countless families, access to safe drinking water remains a daily struggle rather than a basic right. What should be readily available in any modern society has become a constant source of hardship, anxiety and suffering. The consequences of this deprivation extend far beyond inconvenience. Unsafe water sources expose entire communities to waterborne diseases and serious health complications, undermine human dignity and place an enormous burden on already vulnerable households. Children grow up in conditions where access to clean water cannot be taken for granted, while women bear the disproportionate burden of securing water for their families. In a country where access to safe drinking water should be guaranteed, thousands of citizens continue to live in circumstances that no community should be forced to endure. Recognizing the gravity of this longstanding humanitarian crisis, the Pakistan Tehreek-e-Insaf (PTI) government led by former Prime Minister Imran Khan launched the Chapri Dam Water Supply Project in 2020 as a comprehensive and permanent solution to the chronic water shortage affecting the Khattak Belt and adjoining areas. The project was designed to deliver clean and safe drinking water to more than 143,000 residents through the construction of reservoirs, filtration facilities, transmission lines and an extensive distribution network supported by gravity-fed systems and solar-powered pumping stations. For the people of Isa Khel, this was far more than a development project. It represented hope, dignity and the prospect of finally ending a crisis that had persisted for generations. It was the first serious large-scale governmental initiative aimed at permanently resolving one of the most pressing humanitarian challenges facing the region. Following its launch, substantial progress was achieved and approximately Rs. 3.5 billion of public funds were invested in the project's execution. Significant portions of the infrastructure were completed, bringing the project within reach of transforming the lives of tens of thousands of residents. However, following the change in government, progress slowed dramatically and the project remains incomplete due to the non-release of the remaining funds required for its completion. Current PMLN Government in Punjab led by Maryam Nawaz wants to maintain status quo, they feel the project was introduced by Imran Khan and its completion will help PTI. Without realizing its 143,000 people suffering from non-availability of drinking water. This is pure political victimization.show more

Brave PLA soldiers trying to block flood water using... their bodies — a classic image of Chinese state propaganda in action. In the midst of devastating floods, state media showcases People’s Liberation Army (PLA) troops heroically linking arms and forming human walls against raging torrents to “protect the people and the Party.” Videos and photos circulate widely, praising their sacrifice as the ultimate display of loyalty and bravery. But netizens often see through the optics: while soldiers do risk their lives in disaster relief (as in past major floods in Hebei, Anhui, or earlier 1998 events), these dramatic human-shield moments highlight deeper issues — inadequate infrastructure, rushed construction, and a system that prioritizes propaganda over prevention. Why rely on human bodies when better engineering, early warnings, and transparent governance could save more lives? This isn’t just heroism; it’s a window into how the CCP turns real emergencies into loyalty spectacles. What do you think — genuine sacrifice or carefully staged narrative for the cameras?show more

🧵Another personal thread dedicated to an Israeli reservist who... served during the first months of the genocide. This time it's Ariel Mualem, a D9 operator who served in Gaza. In mid-December his unit raided Kamal Adwan hospital and abducted the hospital director, Ahmad Kahlout. Kahlout was then tortured by the Shin Bet and forced to give a "confession", on camera, for supposedly being a Hamas militant and for using the hospital as a "military base" of Hamas. Mualem shared a video of the forced confession on his Instagram story, and wrote: "Take a good luck at this d*ck". In the following story we can see the hospital director being abducted, while cuffed. Mualem captioned the video "Human garbage🤮" and "Here he is, not such a hero after we got to him" A year later, Ahmad Kahlout is still held captive in one of Israel's concentration camps. Kamal Adwan Hospital is still under constant attacks, in an area where Israel is currently implementing its "final solution", named The Generals' Plan.show more
