Spin an uneven object around the wrong axis and something strange happens: It suddenly flips over even though nothing touches it. This is the Dzhanibekov effect, a beautiful consequence of the Mathematics of rotation.

• Discovery: Soviet cosmonaut Vladimir Dzhanibekov first noticed the phenomenon in 1985 aboard the Salyut 7 space station when a loosened wing nut began repeatedly flipping over in microgravity. 🧑‍🚀

Is the tipping moment calculable? Does the rotation achieve stability? Is there an equation for a completely balanced system, or is the tipping moment affected by non linear initial thrust? Is there a pattern if extrapolated infinitely? Hey @grok , what do you think?

Dzhanibekov effect!

Benzer Videolar

🔩 An unexpected twist in space The Dzhanibekov effect: an object rotating in zero gravity suddenly flips its axis of rotation. This occurs due to differences in the moments of inertia across the three axes, causing rotational instability. Demonstrated by Vladimir Dzhanibekov in 1985, this phenomenon shows how even a simple nut behaves unpredictably in orbit. 🤔

When an object spins in zero gravity about its middle axis, the rotation is inherently unstable, and the object periodically flips 180 degrees mid-flight, a phenomenon known as the Dzhanibekov effect.

The Dzhanibekov Effect: Spin any object with three different moments of inertia in zero gravity. The object will spin stably for a few seconds, then suddenly flip 180° while continuing its rotation, then flip back a few seconds later. It does this indefinitely.

NASA astronaut demonstrating the Dzhanibekov effect. An astronaut noticed this physical behavior of a handle, that turned out to be the proof of a theorem: the tennis racket theorem (also dubbed the Dzhanibekov effect) The Tennis Racket Theorem states that an object with three unique moments of inertia, rotation about the axis of intermediate moment of inertia is unstable, while rotation about the other two axis is stable. The effect is named after the Russian cosmonaut Vladimir Dzhanibekov who discovered this phenomenon while in space in 1985.

In the weightless quiet of orbit, an astronaut sets a simple T-handle spinning — and physics takes over. Rotating around its unstable intermediate axis, the object suddenly flips 180 degrees, again and again, in a mesmerizing demonstration of the Dzhanibekov effect that no amount of ground-based intuition can quite prepare you for.

The "Dzhanibekov effect", seen in a rotating object where it will flip its axis by 180 degrees, is demonstrated in microgravity with our camera.

The YakB-12.7 gun itself weighs about 45 kg, and a loaded ammunition box shifts the center of mass farther from the rotation axis, increasing the offset between the recoil line and the rotation axis. this recoil-induced torque can easily spin the platform and the operator with it

Physicists in Okinawa have floated a diamond about a centimetre wide and pushed it up and down using nothing but the spins of electrons inside it, pumped by pulses of green laser light. That object is roughly a hundred million times heavier than anything moved by spin force before. So, a quantum force now shows up directly on something heavy enough for gravity to matter.

If You Love Mathematics and Physics, You'll Love Control Systems Episode 1 Control Systems are the craft of keeping something doing what you want, even when the environment is pushing back. You simply measure what's happening, compare it to your goal and apply correction over and over, many times per second. We need Control Systems because the real world is noisy and unforgiving. Loads change, wind happens, sensors lie, actuators saturate, and tiny errors snowball into failure unless you actively stabilize. In this animation, a cart must keep an upside down stick from falling while we shove it, add gusts, change the weight mid-run, and force it to track new positions. The Controller keeps nudging and braking so it stays upright instead of tipping over. Subscribers can get Python Script on Request.

When you make a wormhole, you're not accelerating the object, you're manipulating the medium. That's why it looks like the object simply slips out of spacetime. The wormhole works just like in a wave pool with an implosive singularity at the center. This plane is being sent backwards perpendicular to the axis of the orbs rotation.

A stunning view as an iceberg flips over in Argentina. 🧊⁣ This iceberg phenomenon is rare and known as "iceberg calving." It is the breaking of ice chunks from a glacier. If the center of gravity of the chunk is high enough, it can even flip over the ice chunk.⁣

This strange ceramic model of an ox on four wheels was found in Cherkaska oblast, Ukraine. Dating to around c. 3950 - 3650 BC, it might be the oldest known wheeled object in the world. It could be a ritual object or a even child’s toy.

What Happens When a Black Hole Does More Than Fall? In General Relativity, a rotating Black Hole is described by the Kerr Metric. Its spin does something strange to spacetime... it drags the geometry around with it. The horizon sits at r₊ = M + √(M² - a²) but outside it there is another surface, the Ergosphere, r_E(θ) = M + √(M² - a²cos²θ) Inside that region, Spacetime is being swept around so strongly that remaining still is no longer possible. Every particle, every light thread, every local observer is forced to rotate with the geometry. For this scene, the C-metric acceleration remains alive in the background and the Black Hole still moves through the fabric, pulled along an axial defect. But the main event is Kerr frame dragging. The fabric twists. The Ergosphere breathes. Light paths shear into spirals. Particles that try to cross the region get carried around before falling inward. #GeneralRelativity #BlackHole #KerrMetric #FrameDragging #Ergosphere #Spacetime #EinsteinEquations #Astrophysics #Physics

Working on a new test of the Dzhanibekov part of ECDO. Earth currently spins near its maximum inertia axis, C, so it’s stable. A Dzhanibekov instability requires the spin to approach the intermediate axis. So, how much mass redistribution would be required to change the inertia tensor enough to make that happen? I’m using the same tomography models and LLSVP geometry from my preferred axis work.

You’ve heard of the Butterfly Effect 🦋 You’ve heard of the Mandela Effect 🧠 But have you heard of the Agent Smith Effect? 👀 It’s what happens when you start waking up… and suddenly the people around you start defending the matrix like their life depends on it.

A White Hole is a Black Hole Running Backward A Black Hole is famous because it lets things fall in, but never lets them come back out. A White Hole is the time-reversed version of that idea. In the full Schwarzschild solution of General Relativity, the Black-Hole region and the White-Hole region appear as two different causal parts of the same exact geometry. Outside the horizon, the metric is the usual Schwarzschild metric ds² = -(1 - 2M/r)dt² + (1 - 2M/r)⁻¹dr² + r²dΩ². The horizon sits at rₛ = 2M, using G = c = 1. For an ordinary Black Hope, future-directed paths can cross this surface inward. Once they do, they cannot return to the outside universe. For a White Hole, the arrow is reversed and particles and light can come out from the horizon, but outside observers cannot enter it. No one has observed a physical White Hole. It may be an ideal solution rather than an object that nature actually forms. But as Mathematics, it is one of the strangest lessons of General Relativity: The equations allow a horizon that throws the universe outward. #WhiteHoles #GeneralRelativity #Schwarzschild #Spacetime #BlackHoles #Cosmology #Physics #Mathematics #Astrophysics #Astronomy
