Ah....

september 11

On the morning of Sept. 11, 2001, 19 men hijacked four airplanes and flew them into landmark buildings in New York City, Washington, D.C., and a field in Pennsylvania. American Airlines Flight 11 and United Airlines Flight 175 flew into the World Trade Center towers, which caused both skyscrapers to collapse. American Airlines Flight 77 crashed into the western side of the Pentagon, which houses the country's military leaders. The fourth plane, United Airlines Flight 93, crashed near Shanksville, Pa., after some of the passengers attempted to regain control. The four planes crashed between 8:46 and 10:03 a.m. Eastern time. Then-President George W. Bush, at a school in Florida at the time of the attack, told the nation hours later that officials believed the attacks were linked.

Newton's First Law

Hola.. Kevin here. Today we or I... am gonna talk about Newton's first law.... This is a very intresting topic so I hope you enjoy.

Force: A force is a push or a pull.Throwing a ball. Your hand exerts a force on the ball, and the ball accelerates forward until it leaves your hand. Really weird right?! . A soccer ball sits on the ground until you kick it!.

MoTion...

What is Speed and Velocity?

Velocity is Speed with direction,like a plane you are in Brazil and you are goin to Mexico and the Speed is 300mph that  is Velocity.


Speed is different,Speed is only the speed you are goin like 30mph ,but there is a different  type of Speed like: Averege Speed  







My favorite song xD

ah.... back to the school...! vv






 Hola!

 





Hi!?



ah... ah... ah... well... this is a new year (yay?)  I have new goals...! They are play "call of duty black ops" and reach   prestige level 14 :D nah...!  they are study,work more,I think I can do it... I will try  xD

Q.why this picture? A.who knows...





oh... well... so... have  a... good day?

black hole

A black hole is a region of space from which nothing, not even light, can escape. The theory of general relativity predicts that a sufficiently compact mass will deform spacetime to form a black hole. Around a black hole there is an undetectable surface called an event horizon that marks the point of no return. It is called "black" because it absorbs all the light that hits the horizon reflecting nothing just like a perfect black body in thermodynamics.Quantum mechanics predicts that black holes emitradiation like a black body with a finite temperature. This temperature is inversely proportional to the mass of the black hole, making it difficult to observe this radiation for black holes of stellar mass or greater.

Black holes of stellar mass are expected to form when heavy stars collapse in a supernoOOOOoooOOooOOOoooOOoOva * xD* at the end of their life cycle. After a black hole has formed it can continue to grow by absorbing mass from its surroundings. By absorbing other stars and merging with other black holes, supermassive black holes of millions of solar masses may be formed.

Simulation of gravitational lensing by a black hole, which distorts the image of a galaxy in the background 

gravitational lensing refers  to a distribution of matter between a distant source and an observer, that is capable of bending (lensing) the light from the source, as it travels towards the observer. This effect is known as gravitational lensing and is one of the predictions of Albert Einstein's



Only 2 days more of school:(

the people who did something in the past... :(

Francis crick 

Born: 8 Jun1916

Died: 28 Jul 2004
Location of death: San diego california
Cause of death: Cancer -Colon  :( (poor guy) :P

was an english molecular biologist and neuroscientist, and most noted for being one of two co-discoverers of the structure of DNA molecule in 1953 together with James Watson







*Nobel Price The Nobel Prize in Physiology or Medicine*



for their discoveries concerning the molecular structure  of nucleic acids and its significance for information transfer in living material he won the nobel prize *in 1962* with James Watson.... :S                                      

During the remainder of his career, he held the post of J.W. Kieckhefer Distinguished Research Professor at the salk Institute for biological studies in la jolla, california.

James Watson  

James Watson born April 6, 1928 is an American molecular biologist, geneticist, and zoologist, best known as one of the co-discoverers of the structure of DNA with Francis Crick 

In 1956, Watson became a junior member of harvard university's Biological Laboratories, holding this position until 1976, promoting research in molecular biology. Between 1988 and 1992, Watson was associated with the national Institutes of help, helping to establish the Human genome project .Watson has written many science books, including the seminal textbook The Molecular Biology of the Gene *1965* and his bestselling book the double helix*1968* about the DNA structure discovery.



Book : The Double Helix

In 1968, Watson wrote The Double Helix  one of the modern Library's100 best Nonfiction book\- The account is the sometimes painful story of not only the discovery of the structure of DNA but the personalities, conflicts and controversy surrounding their work. Watson's original title was to have been Honest Jim in that the book recounts the discovery of the double helix from his point of view and included many of his private emotional impressions at the time. The book changed the way the public viewed scientists and the way they work

June 16, 1902 and SHE! die September 2, 1992 *ja!*
the 1983 Nobel Laureate in physiology  was an American scientist and one of the world's most distinguished cytogenetics (If you don't know what is cytogenetics ! :P)

She studied Chromosomes and  how they change during reproduction in maize
she developed theories to explain the repression or expression of genetic information from one generation of maize plants to the next....
