This would be fine if the measurement of the electron spin were always up and the measured spin of the positron were always down. But because of quantum mechanics, the spin of each particle is both part up and part down until it is measured. Only when the measurement occurs does ...
What is a polar vortex? What is the Gulf Stream? What kind of air stream does a jet engine produce? What are prevailing winds? What is a jet engine turbine? What is jet engine surge? What does polar mean in science? What is a cycle on a jet engine?
What is a vortex in a tornado? What is the polar jet stream? What does a polar jet stream do? What are polar jet streams? What is a multiple-vortex tornado? What is a polar cataract? What does polar mean in science? What is magnetic resonance? What is a magnetic pole? What is a...
The downward flow of the water into the drain begins to rotate, and as the rotation speeds up, a vortex forms. Why does the water start rotating? There are many explanations, but here's one way to think about it: Imagine yourself as a particle in the water, suddenly pulled toward the...
The planetary mill is used for attrition. A wet scrubber is an instrument that has paddles in water turn in the opposite direction, which causes two vortexes into each other. Everything present between the vortex collides and gets apart. ...
Among the terms used to describe wintery weather, the most dreaded might be “polar vortex.” The ominous term sounds like some earthly black hole trying to kill us with Arctic air. So what exactly is a polar vortex, and why do we keep hearing about it year after year?
Another theoretically possible type of beta decay is neutrino-less double-beta decay. In this form of beta decay, a nucleus would decay to two protons by emitting two electrons. This form has never been observed. If neutrino-less double-beta decay exists, it would mean that the neutrino has...
Conservation is assumed to be born in the phase, just as momentum is for instance. In other words, all known phenomena in physics are deterministic, classical and real, in the sense that information does propagate locally and experiments conducted statistically do hide latent variables....
What is a cap block in botany? What is global warming? What is a cape in atmospheric science? What is the Larsen Ice Shelf? What is the role of an ice shelf? What does condensation funnel? What is a carbon reservoir? What is the latent heat of fusion for ice? What is glacial pluck...
Schools, then, are at the centre of the vortex. We need to respond to the structural inequalities that contribute to our educational failures. Restoring serious debate on the purpose and nature of education will be difficult, requiring that we develop trust in one another (Sahlberg & Walker, ...
