Came news the other day I heard on the radio out shopping
that somebody had discovered a molecule-like thing with four quarks—whereas in
physical reality, until recently anyway, the max was three, the minimum two,
the three appearing in protons and neutrons, the two in pions and kaons in
cosmic rays.
Reminded of that this morning, I went looking and found the
story in a Nature press release here.
The discovery was made at the Institute of High Energy Physics in Beijing by
the Belle Collaboration using a particle collider in Tsukuba, Japan.
The name of this elementary particle was introduced by Murray
Gell-Mann. He chose a line from James Joyce’s Finnegan’s Wake, pleased by the number three; it is
the number of quarks in every atom. The novel itself is written in the poetic wirr-warr that
language is when it is heard—rather than read on paper. I’ve managed to find
the actual quote (here),
and it sounds to me like Mister Mark was buying beer—by the quart. But then my
ears ain’t used to Irish-English:
Sure he hasn't got much of a bark
And sure any he has it's all beside the
mark.
But O, Wreneagle Almighty, wouldn't un be a
sky of a lark
To see that old buzzard whooping about for
uns shirt in the dark
And he hunting round for uns speckled
trousers around by Palmer-
stown Park?
Hohohoho, moulty Mark!
You're the rummest old rooster ever flopped
out of a Noah's ark
And you think you're cock of the wark.
Fowls, up! Tristy's the spry young spark
That'll tread her and wed her and bed her
and red her
Without ever winking the tail of a feather
And that's how that chap's going to make
his money and mark!
Delights me when
something really new happens in physics. I might even live long enough to see
someone discover the missing graviton (see this earlier
post on the subject).
