Slow Down!

2008-06-12T05:24:00.000-07:00

This is a poem written by a teenager with cancer.

She wants to see how many people get her poem.

It is quite the poem. Please pass it on.

This poem was written by a terminally ill young girl in a New York Hospital .

It was sent by a medical doctor -

Make sure to read what is in the closing statement
AFTER THE POEM.

SLOW DANCE

Have you ever watched kids

On a merry-go-round?

Or listened to the rain

Slapping on the ground?

Ever followed a butterfly's erratic flight?

Or gazed at the sun into the fading night?

You better slow down.

Don't dance so fast.

Time is short.

The music won't last.

Do you run through each day

On the fly?

When you ask How are you?

Do you hear the reply?

When the day is done

Do you lie in your bed

With the next hundred chores

Running through your head?

You'd better slow down

Don't dance so fast.

Time is short.

The music won't last.

Ever told your child,

We'll do it tomorrow?

And in your haste,

Not see his sorrow?

Ever lost touch,

Let a good friendship die

Cause you never had time

To call and say,'Hi'

You'd better slow down.

Don't dance so fast.

Time is short.

The music won't last.

When you run so fast to get somewhere

You miss half the fun of getting there.

When you worry and hurry through your day,

It is like an unopened gift....

Thrown away.

Life is not a race.

Do take it slower

Hear the music

Before the song is over.

Do you like scary movies?

2008-05-10T04:08:00.000-07:00

Hey are you a scary movie lover. Well me too. I watch those sci-fi mixed scary movies. What about you. There is a new really cool scary movie released.

In my opinion frontiers will define what is horror movies. I mean you should watch the trailer and then you will understand.

This Horror Movie Horror Movie is said to be too horrific for main stream theaters. Cool is not it. Now i'm so excited to to see this. Hope it will keep up to my expectations.

It is going to be released on some selected theaters on 9th MAY. And it will be available on unrated DVD versions from may 13th. Now you can understand why it is unrated. I mean if it is to be rated in known guild lines, then half of the film will be cut off. So i think it's better not to rate it, so the value of the film will be remained.

You can see a trailer of the film at www.frontiersunrated.com

Even though it seems a great movie. You have to watch it to realize what it really is. I mean some movie trailers can be misleading some times. It's true with some movies. But i don't say that this will be such a situation.

Ohh forgot something, through their website, now you can order cool, i mean really horrific posters of this new movie.

ARPANET I

2008-05-10T04:02:00.000-07:00

The ARPANET was designed in the 1960s for the US Defense Department, so as to develop new bombproof, distributed packet-switching network technology. It got its name from the provider of the

funds, the Advanced Research Projects Agency(ARPA).

In the autumn of 1969 the first ARPANET computer was connected to the ARPANET's IMP node at the University of California at Los Angeles (UCLA). Doug Engelbart's hypertext-project computer at Stanford Research Institute (SRI) wasthe next. By the end of the year, the network also included the computers at the University of California, Santa Barbara (UCSB) and the University of Utah, i.e. four in all. All the

computers used different operating systems and they were able to talk to each other across the network with equal status. Some years later,

RFC1000 tells the story of these days of the birth of the Internet, in which enthusiastic students played an important part. During the 1970s, the ARPANET grew to connect research institutes and laboratories supported by the Department of Defense in various parts of the USA. Many of these were university laboratories studying data processing and computer networks, which developed the TCP/IP network and its applications for the internet.

Following of civilization

2008-04-26T09:26:00.000-07:00

Landforms and water ways also affected the political relationships of the world’s ancient peoples. For example the rugged landscape of city-states instead of uniting them in to a single nation.. Further more closeness to the sea caused true and sense of civic pride to other parts of the Mediterranean world.

Geography’s impact on world history

2008-04-26T09:03:00.000-07:00

Geographic factors have shaped the out come of the historical events. Landforms, water ways, climate, and natural resources all have helped or hindered human activities. In many cases, people have learned either to adept to their environment or to transform it to meet their needs.

Throughout the units of your text, you will discover how geography has shaped the course of events in world history. Here are some examples of the role that geographic factors have played in the story of humanity.

Cool Technology and new science

2008-04-25T06:03:00.000-07:00

this is a message i received from mr. Hasanuddin. it's interesting, so i thought i will share with you.

Dear Pulasthi,

I liked your "cool" blog. Although your expertise appears to be technical, I would like to tell you of a breaking new item in a different realm of science. The implications of this new model could have profound reaching effects that impact all of technology, and humanity as well.

I am the author of a new cosmological model. The fact that it deductively shows purpose and connectedness between previously considered anomalous phenomena (solar wind, galaxy formation, supermassive galactic central black-holes, nebulae, and how the next Big Bang will occur) it not really of direct concern to either you or technology. There is one very ominous implication that is of concern: the prediction that mini black-holes are stable. This is troubling, because one of the predicted possible achievements of the newly completed world's-largest-machine, LHC, is to produce man's first (and last) synthetic black-hole material. If the model is correct, and LHC achieves this goal, then an unstoppable horrific chain of events could follow. This is actually a technology issue as much as it is a theoretic, particle physics, and moral issue.

Once the danger was made evident, I changed gears with regards to my work. Instead of targeting its release in a peer-review journal, I wrote it with the "lay" science-oriented reader in mind…people like yourself. Why? LHC is scheduled to be turned on for its maiden run this June. There simply is no time to wait for the peer review process. If this model is correct, then LHC must be postponed. The only foreseeable way to do that is through public pressure. Hence the "book." You can download a free copy at http://www.sendspace.com/pro/dl/u56srb or you can buy the published version, The Dominium, at most online bookstores.

Highlighting the concern is the fact that the new model has been debated on my Scientific American blogspace for five months http://science-community.sciam.com/forum.jspa?forumID=300005039 This adds to the level of concern because none of its critics have been able to identify a single flaw with either its logic or science foundations. Three would-be detractors actually ended up supplying three new lines favoring the new models validity.

Please, consider reading the new model (which really "begins" on page 12 of the download) and then writing about it. Public awareness is the only way to prove the validity of any theory. It is also the only way to hope to change the course that we are on.

Sincerely,

Hasanuddin

Data organization

2008-04-13T05:10:00.000-07:00

Data is organized in to following groups. Each group is more complex than the one before. Character, field, record, table/file,database.

Data

2008-04-12T05:54:00.000-07:00

Data consist of facts, text, graphics, image, sounds and video segments that have meaning in the user’s environment. Consider the students in your group or books in the university library. If you are asked to prepare a list of them what do you include in the list?

Globes

2008-04-11T18:33:00.000-07:00

Photographs from space show the earth in its true from a grate ball spinning around the sun. The only accurate way to draw the earth is as a global, or a round form. A globe gives a true picture of the earth’s size and the shape of the earth’s landmasses and bodies of water. Globes also show the true distances and true direction between places.

Wave particle duality (Part-2)

2008-04-11T10:04:00.001-07:00

In order to specify a wave its frequency, wavelength, velocity of propagation, amplitude and intensity have to be specified. To specify a particles its mass, velocity, momentum and energy have to be specified. Further a wave occupies a larger area but a particle occupies just a finite position. It is difficult to accept the idea of “spread out” wave is equivalent to a particle.

Wave particle Duality (Part-1)

2008-04-11T09:41:00.000-07:00

To explain the interaction of one photon at a time, phenomena of photoelectric effect and the Compton scattering, we have to consider light as particles having energy and momentum. We used the laws of conservation of energy and momentum to collision between two particles, the electron and the photon, the same way as done with the collision of two billiard balls and successfully explained the characteristic of Compton scattering.

Wave particle duality

2008-04-10T07:07:00.000-07:00

From the experiment on interface, diffraction and polarization we know for certain light and all electromagnetic radiation are waves. From propagation experiments we know that all travels with the same speed. The speed of light, carrying energy and momentum and their properties can be explained in terms of Maxwell’s equations.

The Five themes of Geography

2008-04-10T05:30:00.000-07:00

The study of geography can be organized around five themes. Location, Place, Human/Environment interaction, Movement, and Region. Geographers use these five themes to study and classify all parts of the earth and its variety of human activity

Compton Effect (Part-8)

2008-04-09T06:42:00.000-07:00

Comparison with Experiment

Theoretical predictions and experimental results are in very good agreement with theoretical prediction confirming the correctness of photon concept and the following.

Photon has momentum
Photon mass is zero
Proves principle of special relativity
Proves the particles nature of radiation

Compton Effect (Part-7)

2008-04-09T06:25:00.001-07:00

Although the electrons are assumed to e stationary they are not as a result. . The scattered photon has varying wavelengths centered at the calculated delta lambda value. Unmodified line represents X-rays scattered by carbon nuclei. Since the nuclear mass is much larger than the electron mass, delta lambda is nearly zero.

Compton Effect (Part-6)

2008-04-08T20:21:00.000-07:00

Comparison with experiment

Experiment curve has
A broad band whereas theory predicts just a single value for delta lambda at a given scattering angle.
Unmodified line is present at all scattering angles.

Compton Effect (Part-5)

2008-04-08T19:50:00.000-07:00

Compton observed that the scattered photons had a wavelength than the wavelength of incident radiation. Compton pointed out that, if the scattering process were considered to be a billiard ball type collision between a photon and an electron, the electron would absorb energy from the photon and recoil, and the scattered photon would have less energy and therefore a larger wavelength than the incident photon.

Compton Effect (Part-4)

2008-04-08T06:49:00.000-07:00

According to the classical theory, when an electromagnetic wave of a certain frequency is incident on a material containing electrons, the electrons will oscillate with the same frequency and re radiate electromagnetic waves of the same frequency.

Compton Effect (Part-3)

2008-04-05T21:23:00.000-07:00

In the Compton Effect Compton assumed that

A photon has the very mechanical property of momentum
The collision between the photon and the electron is a billiard ball type collision between two particles.

Compton Effect (Part-2)

2008-04-05T20:46:00.000-07:00

Arthur Holly Compton used X-rays of very short wave lengths and a carbon target. The energy of a x-ray photon of this wavelength is 17.4 Kev. Since this is much larger than the binding energy of the valance electron in carbon. These electrons can be considered essentially free.
