This is cavitation inside a piston diaphragm pump. Most... engineers spend their entire careers hearing this destructive phenomenon. Almost none ever get to see it with their own eyes. When pressure drops below a critical threshold, liquid instantly flashes into vapor, creating thousands of microscopic bubbles throughout the system. It happens in milliseconds, invisible to the naked eye in standard metal pumps. But when pressure rises again, those bubbles don't just disappear quietly. They collapse violently, sending shockwaves rippling through the metal components. The result is catastrophic. Valves get destroyed. Seals get shredded. Pump chambers get hollowed out from the inside, one microscopic implosion at a time. Cavitation is one of the most destructive forces in industrial fluid systems, responsible for equipment failures that cost thousands of dollars per incident. Engineers have studied it for decades through sensors, pressure readings, and the telltale sounds it makes. But they've never been able to watch it happen in real time. Until now. The clear plexiglass head on this LEWA pump changes everything. For the first time, pump engineers can observe cavitation as it occurs, watching the bubble formation and violent collapse that destroys their equipment. It's like finally seeing the invisible enemy that's been wreaking havoc on industrial systems. This is what happens when engineering innovation meets visualization technology. Sometimes the most powerful breakthroughs come from simply making the invisible visible.show more

This looks like a simple transparent shock absorber filled... with oil. But what you are seeing is one of the most destructive phenomena in fluid engineering. This is cavitation in its true form. The white cloud forming beneath the piston is not foam and it is not air. The oil is literally changing from liquid to vapour at room temperature. When the piston moves rapidly, the oil is forced through tiny passages inside the damper. The fluid velocity increases, the local pressure drops, and if it falls below the oil's vapour pressure, the liquid begins to boil without any increase in temperature. The moment the pressure recovers, those microscopic vapour bubbles collapse almost instantly. And that is where the real damage begins. The destructive forces of cavitation is really not understood well by most. A collapsing cavitation bubble creates shockwaves and high-speed microjets that strike nearby surfaces with enormous local forces. Repeated millions of times, these tiny implosions can slowly eat away hardened metals, destroy precision components and reduce the lifespan of expensive machinery across industries. This same invisible phenomenon is one of the biggest challenges in naval engineering. Ship propellers operating under enormous loads can suffer cavitation erosion, losing efficiency while creating underwater noise. For advanced stealth submarines, that noise can become a major problem because cavitation can reveal their position. Decades of research have gone into specialised propeller designs, pump-jets, surface finishes and hydrodynamic optimisation to delay its formation. The same issues affects hydroelectric turbines that convert the energy of entire rivers into electricity, and industrial pumps that move oil, chemicals and water through critical infrastructure around the world. Perhaps the most remarkable part is that after 4-5 decades of advances in metallurgy, coatings and manufacturing, engineers still cannot simply build a material that is immune to cavitation. The solution is not to make stronger metals forever. It is to understand the fluid dynamics so precisely that cavitation is prevented before in those destructive bubbles ever form.show more

This is why it’s going to take a VERY... long time for our USMNT to get to be at the level of the world’s best. I mean look at the footwork from Romero of Argentina in a semifinal match for the World Cup. Under this pressure, a CENTRAL DEFENDER pulls off this dribble to get himself out of trouble …pulling it out of his own ass. It will be a long time before we pull off creating a defender of this caliber able to do this with all the weight on their shoulders as they try and play it out of the back.show more

Today we’re introducing 2 HUGE changes to the pump... fun mechanism (in beta) 1) Coin creation is FREE 2) Coin creators receive 0.5 SOL (~$80) when their coin completes its bonding curve How does it work? 1) Instead of the creator having to pay ~$2 for coin creation, this cost is now paid by the first buyer of the coin *This unlocks the use case of someone creating a coin without buying any of its supply* Why would they do that? 2) They receive 0.5 SOL (~$80) if the coin completes its bonding curve. - This gets paid out from the pump fun migration fee (now only 1.5 SOL) - it is paid regardless of whether the coin dev has ever held the coin or still holding the coin - The reward also gives an incentive for all devs to get their coin to 100% Final notes: - when the coin is created, it’s not put onchain until someone buys it. That’s why sometimes, there may be a difference between the time it launched on the pump fun interface and when it launched on mainnet (what you will see on solscan, for instance)show more

This is an 80,000-tonne hydraulic forging press from China’s... Northern Heavy Industries, one of the largest metal-forming machines ever built. But it is not simply a machine that bends metal like traditional presses do. At this scale, forging is about changing the internal structure of the material itself, compressing the metal, refining its molecular grain flow and eliminating hidden defects that could cause failure decades later. Machines like this are used to create some of the most critical components on Earth, aircraft landing gear, titanium aerospace structures, nuclear reactor components, massive gas turbine rotors and ship propulsion shafts. The metals being forged are among the most advanced engineering materials available, ultra-high-strength steels, titanium alloys and nickel-based superalloys designed to survive extreme temperatures, pressure and millions of fatigue cycles. An 80,000-tonne press is an industrial ecosystem by itself. The press, hydraulic systems, furnaces, manipulators and supporting infrastructure can require hundreds of millions of dollars in investment, with hydraulic systems requiring tens of megawatts of power to control forces equivalent to thousands of tonnes. The biggest industrial machines often do not make the final products. They make the materials that make those products possible.show more

Kedarnath is a tremendous space. The utterance of the... sound “Shiva” attains a completely new dimension and significance in Kedar. It is a space which has been specially prepared for this particular sound. When we utter the word “Shiva,” it is the freedom of the uncreated, the liberation of one who is not created. It is almost like on this planet, the sound “Shiva” emanates from this place. For thousands of years, people have experienced that space as a reverberation of that sound. This is also a place that has witnessed thousands of Yogis and mystics of every kind. When I say every kind, you cannot imagine those kinds. These are people who made no attempt to teach anything to anyone. Their way of making an offering to the world was by leaving their energies, their path, their work – everything – in a certain way in these spaces.show more

If you ever get the chance to go to... Normandy, take it. Don't just visit it-take your time and let it sink in, because it is one of the most humbling experiences I've ever had. Standing there, looking out across those beaches, you can almost feel the weight of what happened there. It's hard to fully understand what those soldiers went through until you're standing in that place, realizing the courage it took just to run toward that shore. The beauty of Normandy is quiet and powerful, but so is the sacrifice it represents. The rows of white crosses, the history in the ground, the silence in the air-it all reminds you that freedom came at a tremendous cost. It's the kind of place that stays with you long after you leave. It makes you grateful, reflective, and a little more aware of how much was given for the life we live today. Normandy is more than a battlefield. It is a lesson in sacrifice, bravery, and remembrance. 🙏🇺🇸🙏show more

🎥 + 💭: sinothando "There’s something almost unreal about... thresher sharks. 🦈 That impossibly long tail, the slow and graceful way they move through the blue. It looks like an animal from somewhere else. Seeing one takes patience. They spend most of their time deep, and the encounters happen early, before sunrise, at cleaning stations on seamounts where they rise up to get worked over by wrasse. You get in the water in the dark and you wait. And for all that presence, a thresher is shy. They spook easily, they keep their distance, and they pose no threat to a diver. What they do matter to is the reef itself. Predators like this keep the whole system in balance. A quiet reminder that the most extraordinary animals are usually the most misunderstood." #MarineMonday #ThresherSharkshow more

Apparently, I saw this video online and I decided... to share. What this worker is applying is called bitumen, or what many of us know as bituminous coating. Most people think a wall is a solid, impenetrable block, but in reality, it is more like a sponge. Concrete and blocks have microscopic pores that pull water from the earth through a process we call capillary action. This thick black substance is the shield that stops that water from climbing up into the house. It is not about making the wall look good because this part will be buried under the dirt forever. It is about creating a skin that water cannot breathe through. When do you need to do this? The need for this arises because the soil is a very aggressive environment. Water is not your only enemy.. The ground also contains salts and sulfates that want to eat away at the cement. If this moisture finds its way to the steel bars inside the columns, those bars will start to rust. And when steel rusts, it expands, and that expansion is what cracks the concrete from the inside out. This coating is the only thing standing between your foundation and that kind of slow destruction. Thats is why if you see wet patches at the bottom of your walls inside your house, it usually means someone skipped this step or did it poorly during construction. You can apply this anytime you are building parts of a structure that will stay in contact with the ground. It is common in areas where the water table is high or where the soil stays damp for most of the year. This is a one-shot opportunity. Once you backfill the soil, you can never go back to fix it without a lot of expense and a lot of digging. It is about having the foresight to protect the heart of the building while it is still exposed. Please don’t ignore this if you need to. If you ignore it now to save a bit of money, you will be funding the future decay of your own home. I hope this helps.show more

The fascinating concept of Non-Newtonian fluids, which transition from... a liquid state to a solid-like state when pressure is applied, has a rich history that spans several centuries. The study and understanding of these peculiar fluids have evolved over time, leading to a wide range of practical applications and scientific insights. One of the earliest references to Non-Newtonian behavior in fluids dates back to the 17th century when Sir Isaac Newton formulated the basic principles of fluid mechanics. Newton's laws of fluid motion primarily applied to Newtonian fluids, which exhibit constant viscosity and flow behavior regardless of the applied force or pressure. However, it soon became apparent that not all fluids behaved in this predictable manner. In the mid-19th century, a scientist named Thomas Andrews made significant contributions to the understanding of Non-Newtonian fluids. Andrews conducted groundbreaking experiments with carbon dioxide, revealing that under high pressure, this gas could transform into a liquid. This observation marked one of the earliest instances of pressure-induced phase changes in fluids. The term "Non-Newtonian" itself was coined in the 20th century to describe fluids that did not adhere to Newton's classical laws of fluid dynamics. These fluids exhibited a variety of behaviors, but one of the most intriguing was their ability to solidify or increase in viscosity when subjected to stress or pressure. One of the most famous examples of such behavior is cornstarch mixed with water, which forms a substance known as "oobleck" that becomes more solid when pressure is applied. In the modern era, Non-Newtonian fluids have found applications in various fields, including food science, engineering, and material science. They are used in products like quicksand, body armor, and even in the development of impact-resistant materials. One of the key insights that emerged from the study of Non-Newtonian fluids is the importance of understanding the relationship between stress and strain, as well as the influence of time-dependent properties on their behavior. This knowledge has led to advancements in rheology, the study of flow and deformation in materials, and has practical implications in areas such as industrial processing, medicine, and the design of everyday products.show more

Sitting here watching my Cybertruck charge with the mountains... of Utah in the background, it hit me again… I really believe this is the most beautiful Tesla ever made. Every angle is different. It looks futuristic without trying too hard, and it fits just as well in the middle of a city as it does surrounded by nature like this. What makes this truck special is so much more than just the stainless steel or design. For me it’s how capable and practical it is. Long road trips, hauling gear, camping, tough weather, and FSD… it feels like THE one vehicle built to do almost everything. I’ve owned and driven many Teslas over the years, and every one has been amazing in their own unique way, but the Cybertruck is the first one that genuinely makes me stop and look back every time I park it. Driving across the U.S. in this beast has only reinforced that feeling. And to me, the Cybertruck is the best vehicle Tesla has ever built.show more

One of the worst things you can ever do... is tell a child that he can never be good enough and that his worth will always mean nothing. The caste system does exactly this. Hearing such sentences even one time can destroy their lives, and they will spend the rest of their lives in a state of anxiety. They will succumb to perfectionism, trying to prove their worth even in meaningless things. They will no longer be able to relax or chill. They will always try to overcompensate. The caste system is one of the most evil systems ever conceived by humankind. And yes, anyone who advocates it, validates it, or even slightly leans toward it is my enemy. I will have no respect for you or your upbringing. This is my stand, and I will take these words to my grave. This is the bare minimum. Everyone must condemn the caste system and try to abolish it. Otherwise, you are a disgusting human being. Thank you ప్రశ్న for this ♥️show more

Doge, Pepe, and Shib all crashed 85-95% after their... initial run ups. Troll is currently right around this mark. Many will wait for a dip to bid, thinking they have missed the “pump”. Nobody has seen a pump. Every single time $Troll gets going(has had 2 legs thus far), it runs harder than anyone believes it can simply due to the fact that it is a top 3 meme ever and subconsciously people realize it deserves to be in the billions. The third leg will be no different and it will make the first 2 look like chump pumps. It is one of if not the only meme left that has this kind of reflexivity and has been around for over a year. Buy as much $Troll as you can in the coming months. When risk on comes back fully, you will see Troll run like you have not seen a coin run in a long time. People have forgotten what a worldwide, known meme can do because they trade niche memes all day, they will be reminded of what we are here to begin with. Trade less, $Troll more.show more

This is one of the nicest things about China:... whatever happens to you, you can always count on people's solidarity. This is what just happened to us. We wanted to park our RV right next to Hulun lake for the night but stupidly managed to get it stuck in the sand. Impossible to drive out anymore 😓 Immediately, and I mean immediately, people around us started to pitch in to help. Luckily it so happened that a group of ex-PLA soldiers were having a get-together barbecue 100 meters away from us. They got told about our issue, stopped their barbecue and came to help. They told us "don't worry, no matter what we'll get you out, it's just a matter of time". Before we know it, one of the guys takes the wheel of the RV and the others start pushing. In 5 minutes, job done! RV unstuck and the guys get back to their barbecue. The Chinese are often depicted as cold and distant but my consistent experience is that they're one of the kindest people in the world, always ready to help a fellow human in need!show more

The political establishment in Australia is not entirely stupid,... they just think you are. As they lament the rise of One Nation, they pretend they don't understand it. Because if they showed us that they understand the resons, they then have to make a major admission. Hanson's rise is all their fault. Because the major parties and the faux independents have been on a unity ticket on all of the big problems they have jointly caused for decades. They can’t hide from the messes they have caused, so now they want to blame everyone else but themselves. Today, on ABC’s Insiders, Annabel Crab belled the cat, as Karvelas did the two step crab walk. Annabel correctly diagnoses the political situation here right now. It is not a love for Hanson, or One Nation that is causing the surge, but a total lack of faith in the other offerings. It almost does not matter what Hanson says or does, because her greatest strengths are that she is there, and she is not one of them. Those are enduring traits and the more the major parties hit her, the more the media carry on about her, and the more the establishment present her as a “deplorable”, the more people they will push in her direction. It is like they are in quicksand... the more they struggle, the deeper they sink. People are growing ready for wild political change. A worsening economy and a growing collapse in social cohesion has put the nation on edge. The big end of town want to pretend everything will be fine when the latest special envoy delivers their newest report, but nothing changes. Nothing changes because nothing is supposed to change. Because the government, the opposition and their Green Teal cheer squads want things just the way they are. They didn’t just pass all of the enabling legislation for no reason. There are real beneficiaries of these things, it is just that none of the beneficiaries are the Australian people. Australians have broadly been the target of the changes made to benefit foreign interests, the political class and major corporations. We have been targeted for so long it is impossible not to feel the cross-hairs of the scope resting on our forehead. Hanson and her team simply have to talk about that feeling... they don’t even have to have a solution. Because when the establishment continues to pretend the problems don't exist, just acknowledging the pain is enough to earn a vote. Annabel nails this sentiment in just a few words. Right as Karvelas changes the subject, because it is not that this isn’t obvious, it is because Karvelas is there to cover it up, and hit Hanson’s credibility again. Fuelling the vicious cycle of the rise of the outsider. Unless something significant changes in the establishment, and I don’t expect it will, there will be major upheaval at the next election. Most people will not be voting for their favourite party or person, they will primarily be voting against the status quo, because in their minds, it could not possibly be worse than what we have experienced for decades... but it just might be a little bit better. And that is a risk worth taking. After all most of us like a punt. I just want Australia back.show more

THE FINAL STRETCH BEFORE EVERYTHING CHANGES….💫🛸💫 💥Note to Anons-... Patriots: You have been through more than you let on, more than anyone knows, the sleepless nights, the relatives, friends and strangers that laughed at you. Moments you questioned yourself-times you had nothing left; but still chose to believe. You held on when others folded. You stayed when it would of been easier to walk away. That makes you rare, dangerous and destined. “You may not feel it right now,” but this is THE FINAL STRETCH before everything changes. There will come a day when you sit in stillness and remember the version of you who refused to “Give Up.” The one who showed up broke, exhausted and ridiculed; but never let go of the vision. That day is coming—and when it does you will cry; not because you are hurting-because it all finally made sense. All the pain, doubt, delays and all the missed exits. It wasn’t punishment; It was preparation. You weren’t meant to get rich fast, You were meant to become someone “Unshakable.” You are awake,alive and know this matters. Now, you’re too far in to turn around and way too close to fold under pressure. The storm is loud but your intuition is louder and it’s been screaming from the beginning; “Hold On-Just Hold.” This moment is once in a lifetime, you won’t see it again. NOT LIKE THIS-NOT AT THIS PRICE-NOT WITH THIS SETUP. So breathe, trust your gut, Silence the noise and when this ends-when it finally ENDS-you’ll be the one they come to asking “HOW YOU KNEW?” And you’ll smile 🙂because deep down, way down; “YOU ALWAYS KNEW.” I’m proud of you, you’re almost there; Finish The Mission-I Love You.show more

Ever drink water directly from a creek or lake?... This is my son, drinking from a little lake in Jasper, on the Chaba trail in 2014. I do it all the time on my hikes. It's the number one topic I get on YouTube. Everyone tells me it's dangerous. That's because most Canadians have never seen the inside of a water pipe in their community. I usually convert about 90% of the folks who come hiking with me. I've never been sick, but I have had upset stomachs. Mostly because of the high dissolved mineral content.show more

WHY ARE WE STILL PAYING ALMOST FOUR DOLLARS A... GALLON WHEN OIL IS NEARLY $70 A BARREL?! Oil is trading in the seventies right now. Go back and check the history books. The last time crude sat in that range for any real stretch, gas was closer to two dollars and sixty cents a gallon. Today the national average is sitting near four dollars. Something does not add up, and Americans know it. There is an old saying in this business. Prices rise like a rocket and fall like a feather. Economists even have a name for it. The rocket and feather effect. When oil spikes, the pump reacts overnight. When oil drops, that same speed mysteriously disappears. The industry has a story ready every time. They say they are still selling expensive oil bought weeks ago, so prices cannot fall yet. Fine. But watch what happens the moment tensions with Iran flare up. Oil ticks up four or five dollars a barrel and somehow pump prices jump forty or fifty cents overnight, on oil the stations already had sitting in the ground bought at the old cheaper price. You cannot have it both ways. Slow to fall because of old inventory, instant to rise regardless of it. That is not a supply chain. That is a shakedown. Trump has pushed harder than any president in a generation to open up drilling, cut red tape and increase the actual supply of American energy. That is supposed to be the whole point. More supply, lower prices, real relief for working families filling up their trucks. Families are doing the math at the pump every single week. They are not confused. They can see a rocket going up and a feather coming down, and they are done pretending it is a coincidence.show more

I love your observation and it will make me... discuss the remarkable adaptations that prevents giraffes from passing out and suffering brain damage when bending to drink water and when standing up. ADAPTATION 1 Did you know that the distance from the giraffe's heart to its brain is about 2 meters or more? That's more than the average humans height! Pumping blood up to that great distance and working against gravity is not a joke! That's where the giraffe's heart comes in. A giraffe's heart is unique in several ways. First, it is quite large, weighing up to 11kg and measuring about 2 feet long, which is necessary to pump blood up the long neck to the brain. Second, it has thick walls to generate enough pressure to overcome gravity and push the blood up to the head. ADAPTATION 2 Now, let's move to the neck. Before discussing the incredible roles the valves in the jugular veins perform, let's look at what can happen without them, and then the solution. Problem I: When the giraffe bends down to drink, blood rushes downward to the head. Gravity pulls a huge volume of blood toward the brain, which could cause dangerously high pressure in the head and potentially burst vessels or cause other damage. Solution: They have one-way valves in the jugular veins (the large veins in the neck). These prevent blood from rushing backward uncontrollably into the head when lowered. These valves help regulate and slow the downward flow, avoiding a massive pressure surge to the brain. Also, the neck veins can act as temporary blood storage unit, storing over 1 litre of blood. This prevents blood from flooding the brain and also reduces the amount of blood returning to the heart. As a result, the heart pumps with lower pressure while the head is lowered. This buffers the high head pressure that gravity would otherwise cause. Problem II: When they raise their head up immediately after drinking, blood pressure drops sharply to the brain. A sudden drop could starve the brain of oxygen, causing fainting. This is similar to but much more extreme than the dizziness some people feel when standing up quickly. Solution: When the giraffe raises its head, that stored blood rushes back to the heart quickly. The heart responds with a strong, high-pressure beat that immediately pushes blood back up to the brain, preventing a dangerous drop in cerebral pressure. Impressive right?!show more
