Astrophysics for Poets


A Vast and most Excellent Science

How often at night
When the heavens were bright
with the light of the glittering Star and Moon
have I stood there amazed and asked as I gazed
if their glory exceeds that of ours.

Pengalaman adalah:

Jika Hidup ini seumpama rel kereta api dalam eksperimen relativitas
maka pengalaman demi pengalaman yang mengempur kita dari waktu ke waktu
adalah cahaya yang melesat-lesat di dalam gerebong di atas rel itu.
Relativitasnya berupa seberapa banyak kita dapat mengambil pelajaran dari pengalaman yang melesat-lesat itu,
maka analoginya adalah jika pengalaman yang sama dapat menimpa siapa saja,
namun sejauh mana dan secepat apa pengalaman itu memberi pelajaran pada seseorang,
hasilnya akan berbeda, relatif satu sama lain.
-Andrea H-

Anyone who has never made a mistake has never tried anything new.

E= mc2 and All That

What is matter? - Never mind.
What is mind? - It doesn't matter.

The Birth of Relativity

But in Physics I soon learned to scent out the paths that led to the depths, and to disregard everything else, all the many things that clutter up the mind, and divert it from the essential, the hitch in all this was, of course, the fact that one had to cram all this stuff into one's mind for the examination, whether one liked it or not.

"The Velocity of light is the same for all observers, in all direction, regardless of the motion of either the observer or the light source"

The Wedding of Space and Time

Light laugh:"There's no use trying."
He said:"One cannot believe impossible things."
"I dare say you haven't had much practice" said Moon
"When I was your age, I always did it for 2 hours a day. Why, sometimes I've believed in as many as 8 impossible things before breakfast.

Space-Time: The Fourth Dimension

S2 = L2-(ct)2 = Lo2
Where: L = Distance between two poles way greater than Lo
S = Space-Time separation is equal to Lo
c = Speed of Light
t = Time

-Albert Einstein-

One Last Part for the Machine

With Earth's first clay they did, the last man knead
there of the last Harvest sowed the seed:
And the first Morning of Creation wrote what the last Dawn
of Reckoning shall read.

F=k qQ/r2 (Charles Coulomb law)
where: F= Force of Electricity,
k= a Universal constant,
qQ= are the electric charges to express this in a formula, we define something called"field strength" E,
Coulomb's law become two formulas. E=kQ/r2 & F= qE
-Fitz Gerald, the Rubaiyat of Omar K.-


There is something Fascinating about science. one gets such whole sale returns of conjecture out such trifling investments of fact.

-Mark Twain-

Does the Earth Really Move?

It may be that it does not move, or moves but for some other reason:
Then let it be your boast to prove
(though some may think it out of season and worthily of a fossil Druid )
There is no Electric Fluid.

-James Clerk Maxwell-

Did God Have any Choice?

Within every creature incarnate sleeps the infinite Intelligent unevolved,
hidden, unfelt, unknown-yet destined from all eternities to waken at last,
to rend away the ghostly web of sensuous mind, to break forever it's chrysalises
of flesh, and to pass to the extreme conquest of Space and Time.


"What really interests me is whether God had any choice
in the creation of the world" (H2O)

The Atoms Returns

The telescope at one end of his beat
and at the other end the microscope two
instruments of nearly equal hope

-Robert Frost-

The Universe is not only queerer than
we imagine, it is queerer than we can imagine

-J.B.S. Haldone.-

The Atom and the Quantum

Hail to Max Planck, Einstein, Bohr, Pauli, Broglie, Schrödinger, Feynman,
and Young man in the Future from the worshipful! You are the Master by
whom we are led. Awed by your cryptic and proud affirmations. Each of us,
driven half out of their head, still remains true to you
wouldn't say boo to you, Swallows your theories from Alpha to Zed,
Even if (drink to him, tankards must clink to him!) None of us fathoms
a word you have said

-George G.& H2O-

Particles and Waves

We are trapped by language to such
a degree that every attempt to formulate
insight is a play on words.
(2πrmv = n h)
n = 2πr/λ
n = an integral number
λ = wave length
h = Planck's Constant
2πr = Circle's Constant (Orbit equation)

-Niels Bohr& H2O-

Does God Play Dice?

But you tell me of an invisible planetary system
where electrons gravitate around a nucleus. You explain
this to me with an image, I realize then that you have been
reduced to poetry:
" I shall never know. I have the time to become indignant?
you have changed theories. so that the sciences that was
to teach me everything ends up in a hypothesis,
that lucidity founders in metaphor, that uncertainty
is resolved in a work of art

-A.Camus, The Myth of Sisyphus.-

Schrödinger's Cat

The law of chaos is the law
of ideas, of improvisations
and seasons of belief

The Dreams stuff is made of

Like a gleam in the darkness, we have appeared
for an instant from the black nothingness of the
ever-unconscious matter, in order to make good
the demands of reason and create a life worthy
of ourselves and of the Goal we only dimly perceive
-Andrei Sakharov-

Quantum field Theories
"The nature of a field is completely determined by
the properties of the particle that transmit it,
while the nature of a particle depends solely on
the ways in, which it couples to fields.

QED = Quantum Electrodynamic
α = e2/ħc
QCD = Quantum Color Dynamic (Quantum Foam)
rp = Second root of Għ/c3 = 1,6 x 10-35(power) it is Planck's Length

-Richard Feynman,Julian Schwinger, Murray Gell-mann and George zweig

The whole Shebang

I am astounded by people who want
to "know" the universe when it's hard
enough to find your way around the world

"I HAVE A DREAM" (1963)

"I Have A Dream" is the popular name given to the historic public speech by Martin Luther King, Jr., when he spoke of his desire for a future where blacks and whites among others would coexist harmoniously as equals. King's delivery of the speech on August 28, 1963,

from the steps of the Lincoln Memorial during the March on Washington for Jobs and Freedom, was a defining moment of the American Civil Rights Movement. Delivered to over two hundred and fifty thousand civil rights supporters, the speech is often considered to be one of the greatest and most notable speeches in history and was ranked the top American speech of the 20th century by a 1999 poll of scholars of public address.[1] According to U.S. Congressman John Lewis, who also spoke that day as the President of the Student Non-Violent Coordinating Committee, "Dr. King had the power, the ability and the capacity to transform those steps on the Lincoln Memorial into a modern day pulpit. By speaking the way he did, he educated, he inspired, he informed not just the people there, but people throughout America and unborn generations."[2]
At the end of the speech, King departed from his prepared text for a partly improvised peroration on the theme of "I have a dream", possibly prompted by Mahalia Jackson's cry "Tell them about the dream, Martin!".[3] He had delivered a speech incorporating some of the same sections in Detroit in June 1963, when he marched on Woodward Avenue with Walter Reuther and the Rev. C.L. Franklin, and had rehearsed other parts.[4]

"I am happy to join with you today in what will go down in history as the greatest demonstration for freedom in the history of our nation.
Five score years ago, a great American, in whose symbolic shadow we stand today, signed the Emancipation Proclamation. This momentous decree came as a great beacon light of hope to millions of Negro slaves who had been seared in the flames of withering injustice. It came as a joyous daybreak to end the long night of their captivity.
But 100 years later, the Negro still is not free. One hundred years later, the life of the Negro is still sadly crippled by the manacles of segregation and the chains of discrimination. One hundred years later, the Negro lives on a lonely island of poverty in the midst of a vast ocean of material prosperity. One hundred years later, the Negro is still languished in the corners of American society and finds himself an exile in his own land. And so we've come here today to dramatize a shameful condition.
In a sense we've come to our nation's capital to cash a check. When the architects of our republic wrote the magnificent words of the Constitution and the Declaration of Independence, they were signing a promissory note to which every American was to fall heir. This note was a promise that all men - yes, black men as well as white men - would be guaranteed the unalienable rights of life, liberty, and the pursuit of happiness.
It is obvious today that America has defaulted on this promissory note insofar as her citizens of color are concerned. Instead of honoring this sacred obligation, America has given the Negro people a bad check, a check that has come back marked "insufficient funds."
But we refuse to believe that the bank of justice is bankrupt. We refuse to believe that there are insufficient funds in the great vaults of opportunity of this nation. And so we've come to cash this check, a check that will give us upon demand the riches of freedom and security of justice. We have also come to his hallowed spot to remind America of the fierce urgency of now. This is no time to engage in the luxury of cooling off or to take the tranquilizing drug of gradualism. Now is the time to make real the promises of democracy. Now is the time to rise from the dark and desolate valley of segregation to the sunlit path of racial justice. Now is the time to lift our nation from the quicksands of racial injustice to the solid rock of brotherhood. Now is the time to make justice a reality for all of God's children.
It would be fatal for the nation to overlook the urgency of the moment. This sweltering summer of the Negro's legitimate discontent will not pass until there is an invigorating autumn of freedom and equality. Nineteen sixty-three is not an end but a beginning. Those who hoped that the Negro needed to blow off steam and will now be content will have a rude awakening if the nation returns to business as usual. There will be neither rest nor tranquility in America until the Negro is granted his citizenship rights. The whirlwinds of revolt will continue to shake the foundations of our nation until the bright day of justice emerges.
But there is something that I must say to my people who stand on the warm threshold which leads into the palace of justice. In the process of gaining our rightful place we must not be guilty of wrongful deeds. Let us not seek to satisfy our thirst for freedom by drinking from the cup of bitterness and hatred. We must forever conduct our struggle on the high plane of dignity and discipline. We must not allow our creative protest to degenerate into physical violence. Again and again we must rise to the majestic heights of meeting physical force with soul force. The marvelous new militancy which has engulfed the Negro community must not lead us to a distrust of all white people, for many of our white brothers, as evidenced by their presence here today, have come to realize that their destiny is tied up with our destiny. And they have come to realize that their freedom is inextricably bound to our freedom. We cannot walk alone.
And as we walk, we must make the pledge that we shall always march ahead. We cannot turn back. There are those who are asking the devotees of civil rights, "When will you be satisfied?" We can never be satisfied as long as the Negro is the victim of the unspeakable horrors of police brutality. We can never be satisfied as long as our bodies, heavy with the fatigue of travel, cannot gain lodging in the motels of the highways and the hotels of the cities. We cannot be satisfied as long as the Negro's basic mobility is from a smaller ghetto to a larger one. We can never be satisfied as long as our children are stripped of their self hood and robbed of their dignity by signs stating "for whites only." We cannot be satisfied as long as a Negro in Mississippi cannot vote and a Negro in New York believes he has nothing for which to vote. No, no we are not satisfied and we will not be satisfied until justice rolls down like waters and righteousness like a mighty stream.
I am not unmindful that some of you have come here out of great trials and tribulations. Some of you have come fresh from narrow jail cells. Some of you have come from areas where your quest for freedom left you battered by storms of persecution and staggered by the winds of police brutality. You have been the veterans of creative suffering. Continue to work with the faith that unearned suffering is redemptive.
Go back to Mississippi, go back to Alabama, go back to South Carolina, go back to Georgia, go back to Louisiana, go back to the slums and ghettos of our northern cities, knowing that somehow this situation can and will be changed.
Let us not wallow in the valley of despair. I say to you today my friends - so even though we face the difficulties of today and tomorrow, I still have a dream. It is a dream deeply rooted in the American dream.
I have a dream that one day this nation will rise up and live out the true meaning of its creed: "We hold these truths to be self-evident, that all men are created equal."
I have a dream that one day on the red hills of Georgia the sons of former slaves and the sons of former slave owners will be able to sit down together at the table of brotherhood.
I have a dream that one day even the state of Mississippi, a state sweltering with the heat of injustice, sweltering with the heat of oppression, will be transformed into an oasis of freedom and justice.
I have a dream that my four little children will one day live in a nation where they will not be judged by the color of their skin but by the content of their character.
I have a dream today.
I have a dream that one day down in Alabama, with its vicious racists, with its governor having his lips dripping with the words of interposition and nullification - one day right there in Alabama little black boys and black girls will be able to join hands with little white boys and white girls as sisters and brothers.
I have a dream today.
I have a dream that one day every valley shall be exalted, and every hill and mountain shall be made low, the rough places will be made plain, and the crooked places will be made straight, and the glory of the Lord shall be revealed and all flesh shall see it together.
This is our hope. This is the faith that I go back to the South with. With this faith we will be able to hew out of the mountain of despair a stone of hope. With this faith we will be able to transform the jangling discords of our nation into a beautiful symphony of brotherhood. With this faith we will be able to work together, to pray together, to struggle together, to go to jail together, to stand up for freedom together, knowing that we will be free one day.
This will be the day, this will be the day when all of God's children will be able to sing with new meaning "My country 'tis of thee, sweet land of liberty, of thee I sing. Land where my father's died, land of the Pilgrim's pride, from every mountainside, let freedom ring!"
And if America is to be a great nation, this must become true. And so let freedom ring from the prodigious hilltops of New Hampshire. Let freedom ring from the mighty mountains of New York. Let freedom ring from the heightening Alleghenies of Pennsylvania.
Let freedom ring from the snow-capped Rockies of Colorado. Let freedom ring from the curvaceous slopes of California.
But not only that; let freedom ring from Stone Mountain of Georgia.
Let freedom ring from Lookout Mountain of Tennessee.
Let freedom ring from every hill and molehill of Mississippi - from every mountainside.
Let freedom ring. And when this happens, and when we allow freedom ring - when we let it ring from every village and every hamlet, from every state and every city, we will be able to speed up that day when all of God's children - black men and white men, Jews and Gentiles, Protestants and Catholics - will be able to join hands and sing in the words of the old Negro spiritual: "Free at last! Free at last! Thank God Almighty, we are free at last!"
