Large Hadron Rap
Twenty-seven kilometers of tunnel under ground
Designed with mind to send protons around
A circle that crosses through Switzerland & France
Sixty nations contribute to scientific advance
Two beams of protons swing round, through the ring they ride
‘Til in the hearts of the detectors, they’re made to collide
And all that energy packed in such a tiny bit of room
Becomes mass, particles created from the vacuum
And then…
LHCb sees where the antimatter’s gone
ALICE looks at collisions of lead ions
CMS & ATLAS are two of a kind
They’re looking for whatever new particles they can find.
The LHC accelerates the protons & the lead
And the things that it discovers will rock you in the head.
We see asteroids & planets, stars galore
We know a black hole resides at each galaxy’s core
But even all that matter cannot explain
What holds all these stars together – something else remains
This dark matter interacts only through gravity
And how do you catch a particle there’s no way to see
Take it back to the conservation of energy
And the particles appear, clear as can be
You see particles flying, in jets they spray
But you notice there ain’t nothin’, goin’ the other way
You say, “My law has just been violated – it don’t make sense!
There’s gotta be another particle to make this balance.”
And it might be dark matter, & for first
Time we catch a glimpse of what must fill most of the known ‘Verse.
Because…
LHCb sees where the antimatter’s gone
ALICE looks at collisions of lead ions
CMS & ATLAS are two of a kind
They’re looking for whatever new particles they can find.
Antimatter is sort of like matter’s evil twin
Because except for charge & handedness of spin
They’re the same for a particle & its anti-self
But you can’t store an antiparticle on any shelf
Cuz when it meets its normal twin, they both annihilate
Matter turns to energy & then it dissipates
When matter is created from energy
Which is exactly what they’ll do in the LHC
You get matter & antimatter in equal parts
And they try to take that back to when the universe starts
The Big Bang – back when the matter all exploded
But the amount of antimatter was somehow eroded
Because when we look around we see that matter abounds
But antimatter’s nowhere to be found.
That’s why…
LHCb sees where the antimatter’s gone
ALICE looks at collisions of lead ions
CMS & ATLAS are two of a kind
They’re looking for whatever new particles they can find.
The LHC accelerates the protons & the lead
And the things that it discovers will rock you in the head.
The Higgs Boson – that’s the one that everybody talks about.
And it’s the one sure thing that this machine will sort out
If the Higgs exists, they ought to see it right away
And if it doesn’t, then the scientists will finally say
“There is no Higgs! We need new physics to account for why
Things have mass. Something in our Standard Model went awry.”
But the Higgs – I still haven’t said just what it does
They suppose that particles have mass because
There is this Higgs field that extends through all space
And some particles slow down while other particles race
Straight through like the photon – it has no mass
But something heavy like the top quark, it’s draggin’ its ***
And the Higgs is a boson that carries a force
And makes particles take orders from the field that is its source.
They’ll detect it….

Now some of you may think that gravity is strong
Cuz when you fall off your bicycle it don’t take long
Until you hit the earth, & you say, “Dang, that hurt!”
But if you think that force is powerful, you’re wrong.
You see, gravity – it’s weaker than Weak
And the reason why is something many scientists seek
They think about dimensions – we just live in three
But maybe there are some others that are too small to see
It’s into these dimensions that gravity extends
Which makes it seem weaker, here on our end.
And these dimensions are “rolled up” – curled so tight
That they don’t affect you in your day to day life
But if you were as tiny as a graviton
You could enter these dimensions & go wandering on
And they’d find you…

And the things that it discovers will rock you in the head.

Physics and poetry
Oppenheimer, they tell me you are writing poetry. I do not see how a man can work on the frontiers of physics and write poetry at the same time. They are in opposition. In science you want to say something that nobody knew before, in words which everyone can understand. In poetry you are bound to say something that everybody knows already in words that nobody can understand.

Buon Natale
Ave Maria, gratia plena
Dominus tecum benedicta tu in mulieribus
Et benedictus fructus ventris tui Jesus
Sancta Maria, Sancta Maria, Maria
Ora pro nobis
Nobis peccatoribus
Nunc et in hora, in hora mortis nostrae
Amen. Amen
Ai fantastici frattali
Euclide a suo tempo fu “re” di geometria,
ma molto ammirerebbe chi segue altra via;
ora c’è la “frattale”, perfezionata alquanto,
Mandelbrot, di poi, se ne può fare vanto.
Frattale, in latino è “fractus”; per finire
“spezzato, irregolare” lo si può definire.
Sono frattali i broccoli, le felci, i cavolfiori,
le linee costiere che stanno al di fuori:
esempio è l’Australia e poi, per farla breve,
si può qui menzionare il fiocco della neve.
Superficie frattale è pure una montagna
con cime frastagliate, che sono una cuccagna:
ha tanti figliolini e son pure frattali
ed essi, a loro volta, ne hanno minimali.
Questo si è ripetuto da sempre, all’infinito,
poiché madre natura ha un piano definito.
Le nuvole son anche frattali superfici,
lo sono pure gli alberi, per fronde e per radici.
Illustri matematici, studiando, hanno imparato
a veder chiaramente il volto inosservato
della natura, madre dei magici frattali
che ne costruisce altri, davvero eccezionali.
Noi ammiriamo il tutto con occhi indagatori
e siam riconoscenti a più ricercatori.
Dalle caratteristiche di vari materiali,
astraggono le doti specifiche, plurali.
Il fiocco della neve, in modo sistematico,
in simmetria perfetta appare al matematico;
inoltre egli sa scindere le ramificazioni
frattali, che di felce hanno figurazioni.
Così, con equazioni davvero eccezionali,
vengono realizzati fantastici frattali.
La grafica-computer aiuta i matematici
nello studiare sodo i sistemi dinamici,
quelli che son complessi all’infinito
e fan toccare il cielo con un dito:
bellissimi disegni ha fatto veder loro,
quindi questa ricerca è diventata “d’oro”.
Ringraziamo di cuore chi oggi ne fa parte,
poiché la sua ricerca ha trasformato in arte.

Le altre carte al disotto non vagliono
Con carte a si fanno b monticelli di egual numero c di punti, e la prima carta di ciascun monticello in prospetto vale dieci, s’è figura, undici s’è un asso, dodici s’è un due, e così di seguito. Le altre carte al disotto non vagliono, che un punto ciascuna. Fatti i monticelli, e rese le carte, che sopravanzano, se ve ne sono, chiedesi la formola generale esprimente la somma de’ punti, che fanno le carte in prospetto.
E’ il Problema VI presente in Problemi d’Algebra e di Geometria Analitica sciolti da Cesare Rovida, Professore di Matematica e Direttore del Collegio Imperiale di Milano. Nel testo troviamo il raziocinio per l’equazione, l’equazione del problema, la soluzione, la conclusione, l’applicazione e la verificazione. Fonte Google Libri.
Pi and friends
There once was a number named pi
Who frequently liked to get high.
All he did every day
Was sit in his room and play
With his imaginary friend named i.
There once was a number named e
Who took way too much LSD.
She thought she was great.
But that fact we must debate;
We know she wasn’t greater than 3.
There once was a log named Ln
Whose life was devoted to sin.
She came from a tree
Whose base was shaped like an e.
She’s the most natural log I’ve seen.
