That the Higgs boson sounds like... habanera. No wonder I love Cuban music.

(Sorry if it's been posted before.)

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."

Rather cool to watch indeed.





However, if I read one more comment or see one more stupid fb post about how crooked stuff is messing up one's "OCD", I'll *&@#*. OCD is not about liking things straight and your room - really tidy, nor is it about making sure that your hands are washed really well. It's not a cute little quirk, that makes you seem oh-so-cool when you're gossiping with your girlfriends in the mall (or whatever it is people of this caliber do). It's ugly and intrusive, and always with you, if not wreaking havoc with your brain at this particular moment, then lurking in the background, ready to pounce again.

I wonder why one of the metronomes in the rightmost column took so long to get in sync with all of the others (2:00-2:40). Consider

What can you expect from a far-righter, other than to rock the board (or boat). Who knows what goes on in their addled, hate-filled brains Dodgy

Peeking inside Schrodinger's box - Malik adds that the beauty of the weak measurement is that it does not destroy the system, unlike most standard measurements of a quantum system, allowing a subsequent measurement—the "strong" measurement of the other variable.

This sequence of weak and strong measurements is then repeated for multiple identically prepared quantum systems, until the wave function is known with the required precision.

Everything and everybody in the Universe is related, Bucky, dear (not too sure about the interesting bit, esp. when some folk are concerned, but that's really neither here nor there. Much like me. Rolleyes )

"Flinders University palaeontologist Professor John Long has found evidence to show that four-legged animals first developed the ability to breathe air as ancient fish in water.

The research shows the Polypterus, the most primitive living bony fish, breathes air through large canals on top of its head called spiracles. The discovery marks the first step in the evolutionary transition of similar ancient fishes to the land as tetrapods, or four-legged animals.

Professor Long, the Strategic Professor in Palaeontology at Flinders, said the research points to the likely conclusion that the ancient Gogonasus – which belonged to a group of fish widely regarded by scientists as the ancestors from whom the first land animals evolved – originally developed its breathing abilities using its spiracles.

"But our research shows that the transformation actually started happening within the fish themselves while they were still in water."


(Also, I'm rather taken with the word spiracle. I'm so easy Blush )

Primeval frog. What I like most about the story is not so much about the frog but this:

"But to reach Madagascar from South America, the frogs would have needed to hop along a passageway, possibly through Antarctica, that linked the two landmasses. But that route was submerged underwater by 112 million years ago, Evans said.

That would mean that devil frogs must have diverged from their South American cousins prior to that submergence, pushing back the origin of Ceratophryidae by more than 40 million years, Evans said."
