Impressive dust devil in Greensboro today! These can form on sunny days with strong surface heating. Low pressure develops at the surface as air rises, then you get a swirling motion as air rushes in to fill in the gaps. This is a construction site - full of dirt... show more

🚨🇮🇷🇮🇱 MISSILE LAUNCHERS AND RADARS DESTROYED IN MASSIVE STRIKES ON IRAN IDF: "The Air Force attacked Iran throughout the night, destroying armed surface-to-surface missile launchers ready to launch. In a quick turnaround, the Air Force also attacked launchers that were firing missiles at the State of Israel. In addition, the Iranian regime's surface-to-air missile infrastructure and detection radars were attacked in Iran, as part of the IDF's air superiority over Iranian skies." Source: צבא ההגנה לישראל

Inside a carburetor, air rushes through a narrow tube called a venturi. This restriction forces the air to speed up, creating a sudden drop in pressure. That low pressure acts like a vacuum, drawing raw fuel through tiny jets where it instantly atomizes into a fine mist. This perfect air-fuel vapor is then sucked straight into the engine cylinders to ignite.

This system is called the “Canadian well.” The essence is very simple: at a depth of 2-3 meters, the earth always holds a stable temperature of about +10... +15°C. In the winter, the cold air from the street goes through an underground pipe and heats up before entering the house. ☀️ In the summer, the hot air is cooled down in the same pipe. That is, the earth functions as both a natural conditioner and a heater. It does not replace heating or air conditioning completely, but it greatly reduces costs and makes the air in the house more comfortable 👍

👀🌪️ Check out this dust devil from Warwick, RI today! Amazing! Dust devils form primarily due to strong localized heating of the ground on clear, sunny days with light or calm winds—not from large-scale windy weather. They are a type of dry convective vortex (not connected to thunderstorms like tornadoes). 📹: Leanne Walker #Seeweather #eweather #dustdevil

This 30-ton autonomous planter can sow 400 hectares in 24 hours. It also significantly degrades 400 hectares of soil in 24 hours. A planter of this size aggressively compacts the soil surface and pulverizes the critical soil aggregates. Just look at the plume of topsoil left in the planter's wake. Arguably worse than surface compaction is the subsurface compaction caused by the force of a 30-ton machine traveling over the field. An initial compaction layer develops as deep as 2 feet and continues upward as new hardpan layers form on top of each other with each subsequent pass of the planter. Eventually, the subsurface compaction meets the surface compaction, and what remains is soil with no water-holding capacity, devoid of life, without the ability to cycle nutrients and generally inhospitable to crops. Despite its speed and efficiency, this planter ultimately takes the life out of farming, from the soil on up to the human operator.

American security for the countries of the region It is reported that there is a technical malfunction in the MIM-104 "Patriot" air defense system [an American-made surface-to-air missile system] in Bahrain. As a result of this technical malfunction, a PAC-2/3 type "Patriot" anti-aircraft missile hit a residential building and caused damage in an area on Sitra Island [an industrial and residential area south of Manama] in the south of Manama.

Mossad has released footage of its operations this morning on the ground in Iran, which involved the targeting of surface-to-air missile launchers and ballistic missiles aimed at Israel. Drones were launched and struck a ballistic missile site near Tehran, preventing Iran from launching an immediate response against Israel, while air-defenses were destroyed allowing the Israeli Air Force to carry out strikes against targets in Western Iran.

🌡️ Unusually intense May heatwave in Europe This weekend will bring very high temperatures to southwestern, western, and partly central Europe, locally up to 15 °C above the long-term average. The reason is a persistent high-pressure system over Europe, drawing in hot air from North Africa along its western flank and acting as a so-called heat dome. Air in the center of the high sinks and warms, suppressing cloud formation and allowing more solar radiation to reach the surface. As a result, hot air accumulates near the ground and continues to intensify. Temperatures may exceed 30 °C in western and central Europe, and reach up to 38 °C in southwestern Spain. Numerous daily temperature records are expected to be broken.

So it turns out, it's more than just the name that Apple borrowed. iPhone Duo is the first folding phone I've seen copy the Surface Duo's unique multitasking and windowing system pretty much 1:1! iPhone Duo can treat each half of the folding display as separate, letting you dock an app to one side and view your home screen on the other, just like Surface Duo. The gestures for multitasking are identical between iPhone Duo and Surface Duo too. You drag an app to the side you want and it fills that half of the screen. You can pick the app up and move it to the other side, and everything will dynamically adjust. It even does the "automatic" multitasking that I've raved about on Surface Duo. If you open a link in an app, it'll move the app over and open the link in your browser. Surface Duo did this, and now iPhone Duo does too. I've been waiting for a folding phone to copy the Surface Duo's unique multitasking and windowing behavior, and we finally have one in the form of iPhone Duo. Well done, Apple. Between the wide form factor like Surface Duo, the pen support like Surface Duo, and now the multitasking like Surface Duo... I think Surface Duo fans may have finally found their Surface Duo 3 in iPhone Duo.

This is a dust-devil. These mini tornados are a common thing in the western states of America. Though they are usually harmless, they can cause havoc depending on their size. I am not so sure I would have tried to stand in it. Dirt in my eyes, is not a pleasant experience. 🌪️

🇺🇸 The B-21 Raider just cut its testing timeline from 180 days to 73, completed all test objectives with half the planned missions, and locked in $11.8B in funding. The Air Force is calling it a win on efficiency. They're probably right. But next-generation stealth bombers don't get second chances. Cutting test time by 60% raises a real question: are the gaps small enough that they'll never matter, or are they the kind that only surface when it counts? Speed is great. Speed with holes in the data is a different story entirely. Source: U.S. Air Force

BREAKING: This is another video showing the mass launch of MIM-104D/F surface-to-air missiles by a U.S. Army Patriot PAC-3 air-defense battery deployed next to Muwaffaq al-Salti Air Base in Al-Azraq, Jordan, last night. As you can see, they wasted tens of their highly valuable precision interceptors against incoming Iranian ballistic missiles—to the point that they had nothing left to counter the second and third waves of Iranian attacks.

A Mars rover recorded an unusual movement on the Martian surface, drawing interest from scientists and space enthusiasts. Mars is an active world with dust devils, strong winds, and seasonal dust storms that can move sand and reshape the landscape. In many cases, unexpected motion can be linked to natural weather and environmental processes on the Red Planet. On Mars, even the wind can leave a lasting mark on the landscape. #mars #marsrover #space #nasa #science

The signal for tropical development is getting stronger. This is the Euro AI ensemble. It develops two strong waves exiting the African Coast in 1-2 weeks. The chance of formation of at least one of these is pretty decent. But the trip across the Atlantic won’t be easy, with dusty air in the deep tropics and #elnino fueled strong wind shear in the Caribbean. So if the storm/s form they will struggle for success. Thanks Weather Nerds for the ensemble! #hurricaneseason #hurricane

Bernoulli's Principle It’s a key idea in fluid dynamics named after Daniel Bernoulli. In simple terms: For a fluid flowing smoothly, an increase in the fluid’s speed happens at the same time as a decrease in pressure or a decrease in the fluid’s potential energy. Where: - P = pressure in the fluid - ρ = fluid density - v = flow velocity - g = acceleration due to gravity - h = height above a reference point Bernoulli's Principle basically says that for a fluid that's flowing smoothly, when its speed goes up, its pressure goes down. Think of it like this: fast-moving air or water pushes less sideways than slow-moving air or water. The energy in the fluid stays the same overall, but it shifts between motion, pressure, and height. That's why an airplane wing creates lift. The air moves faster over the curved top of the wing than underneath, so the pressure on top is lower. The higher pressure below pushes the wing up.
