The sun has “flipped upside down”, with its north and south poles reversed to reach the midpoint of Solar Cycle 24, Nasa has said.

Now, the magnetic fields will once again started moving in opposite directions to begin the completion of the 22 year long process which will culminate in the poles switching once again.

“A reversal of the sun’s magnetic field is, literally, a big event,” said Nasa’s Dr. Tony Phillips.

“The domain of the sun’s magnetic influence (also known as the ’heliosphere’) extends billions of kilometers beyond Pluto. Changes to the field’s polarity ripple all the way out to the Voyager probes, on the doorstep of interstellar space.”

To mark the event, Nasa has released a visualisation of the entire process.

No idea who did this, but big up them anyway, beautiful work. Shaving is part of the conspiracy to keep the Western Male in a permanent state of easily manipulatable boyhood.

Word up, I’m always doing/not doing this. Especially on trains.

From Io9:

If you place 32 metronomes on a static object and set them rocking out of phase with one another, they will remain that way indefinitely. Place them on a moveable surface, however, and something very interesting (and very mesmerizing) happens.

The metronomes in this video fall into the latter camp. Energy from the motion of one ticking metronome can affect the motion of every metronome around it, while the motion of every other metronome affects the motion of our original metronome right back. All this inter-metranome “communication” is facilitated by the board, which serves as an energetic intermediary between all the metronomes that rest upon its surface. The metronomes in this video (which are really just pendulums, or, if you want to get really technical, oscillators) are said to be “coupled.”

The math and physics surrounding coupled oscillators are actually relevant to a variety of scientific phenomena, including the transfer of sound and thermal conductivity. For a much more detailed explanation of how this works, and how to try it for yourself, check out this excellent video by condensed matter physicist Adam Milcovich.

This is some very serious, high budget, purest INTERNETS right here.

Wired have the answers to that questions here.
