And, also it shows release of electromagnetic wave while electron jump from outer orbit (n=3) to inner orbit (n=2). And it shows the relation between the energy difference and the frequency of the emitted wave as δE=hv.

h - plank's constant
v- frequency of the released wave.

Niels Henrik David Bohr was born on October 7, 1885, in Denmark as the son of Christian Bohr, Professor of Physiology at Copenhagen University, and Ellen, née Adler.

Niels Bohr received the Nobel Prize in Physics in 1922 for his foundational contributions to understanding atomic structure and quantum mechanics.

Bohr–Einstein debates

The Bohr–Einstein debates were a series of public disputes about quantum mechanics between Albert Einstein and Niels Bohr, who were two of its founders.

Their debates are remembered because of their importance to the philosophy of science.

Niels Bohr had written about these debates in an article titled "Discussions with Einstein on Epistemological Problems in Atomic Physics".

Despite their differences of opinion regarding quantum mechanics, Bohr and Einstein had a mutual admiration that was to last the rest of their lives.

Niels Bohr Quotes

Prediction is very difficult, especially about the future.

Stop telling God what to do with his dice.

If quantum mechanics hasn't profoundly shocked you, you haven't understood it yet.


Never express yourself more clearly than you are able to think.

The opposite of a fact is falsehood, but the opposite of one profound truth may very well be another profound truth.

The best weapon of a dictatorship is secrecy, but the best weapon of a democracy should be the weapon of openness.

There are some things so serious you have to laugh at them

Google Doodle for 374th birth Day of Nicolas Steno

Today (January 11th, 2012) Google shows special Doodle  for marking the 374th birth Day of Nicolas Steno, the Danish anatomist widely regarded as the father of geology.

The doodle illustrates the each letter in the Word "Google"  in a geological style, with fossils in various bottom layers, with a green surface on top.

  Nicolas Steno was a Danish Catholic cleric and scientist who was a pioneer in both anatomy and geology. Pope John Paul II beatified Steno in 1987. (Beatification is the third of the four steps in the canonization process. A person who is beatified is given the title "Blessed".)

As a young man, Steno set out to study medicine, leaving his native Copenhagen in his early 20s for the University of Leiden in the Netherlands. He then studied anatomy in Italy, where his research on shark teeth led him to question, among other things, how one solid object could be found inside another — such as with fossils. His ideas on “solid bodies within bodies” were published in 1669 in his seminal Prodromus dissertation.
Steno, however, would soon leave science behind. Born into a Lutheran family, he converted to Catholicism and was ordained as a priest in 1675 and became a titular bishop two years later.

 Below Doodle is getting displayed on Home page of Google Today (December 23rd 2011).

On clicking this Doodle, Google shows search results for the search Term "Happy Holidays".

A new survey finds Americans by a wide margin prefer the traditional “Merry Christmas” greeting to the non-specific “Happy Holidays.”

According this Survey done by "Knights of Columbus-Marist Pol" nearly two-thirds of adults (64%) think people should say, “Merry Christmas,” while less than one-third (31%) believe the appropriate greeting is “Happy Holidays.”

Ok. Which one you prefer to say? Happy Holidays or Merry Christmas? You can  share your thoughts thro' the comments.




We wish you all Happy Holidays and Merry Christmas.

Google Doodle Celebrates 84th Birthday of Intel's Co-Founder Robert Noyce

Today Google shows below Doodle in its Homepage to celebrate 84th Birthday of Robert Noyce who founded Intel. The Doodle is showing the drawing of a Integrated Chip.

Robert Noyce has the nickname "Mayor of Silicon Valley."

A noted visionary and natural leader, Robert Noyce helped to create a new industry when he developed the technology that would eventually become the microchip.

Robert Norton Noyce was born on December 12, 1927, in Burlington, Iowa, Unites States.




Robert Noyce ran two of the companies that had the greatest impact on the silicon industry: Fairchild Semiconductor and Intel. He also invented the integrated chip (IC), one of the stepping stones along the way to the microprocessors in today's computers. Microchip (IC) is a critical element for modern electronic devices including personal computers, smartphones, video games, microwaves, and cars.

He co-founded Fairchild Semiconductor in 1957. Fairchild was the first successful silicon company. Noyce and Gordon E. Moore founded Intel in 1968. Noyce was granted 15 patents for his inventions in Semiconductor devices field.


At both companies Fairchild and Intel, Noyce introduced a very casual working atmosphere, the kind of atmosphere that has become a cultural stereotype of how California companies work.


Noyce died of heart failure in 1990, at the age of 62.

In his last interview, Noyce was asked what he would do if he were "emperor" of the United States. He said that he would, among other things, "make sure we are preparing our next generation to flourish in a high-tech age. And that means education of the lowest and the poorest, as well as at the graduate school level."
Source - WikiPedia

The Noyce Foundation was founded in 1991 by his family. The foundation is dedicated to improving public education in mathematics and science in grades K-12.


Leslie who is the Author of "Robert Noyce - The Man Behind the Microchip" says Robert Noyce is the Thomas alva Edison and Henry Ford of the Silicon Valley. And, She says Bob Noyce was a risk taking person, he used to show the words "No Guts No Glory."





In the below picture we can see Bob Noyce with Steve Jobs.

Google Doodle for honoring Louis Daguerre who invented the daguerreotype process of photography

By showing Special Doodle in its Home Page, Google is honoring Louis Daguerre who was a French artist and physicist, recognized for his invention of the daguerreotype process of photography. He was born on  November 18, 1787 in France. Today is his 224th birthday.


A professional scene painter for the opera with an interest in lighting effects, Daguerre began experimenting with the effects of light upon translucent paintings in the 1820s.

He invented the Daguerreotype along with Nicéphore Niépce. Louis Daguerre introduced the daguerreotype process to the public on August 19, 1839 at a meeting of the French Academy of Sciences in Paris. 

Before the daguerreotype, photography required hours of exposure and Louis Daguerre's invention reduced it to 20-30 minutes

The daguerreotype  was the first commercially successful photographic process. The daguerreotype is a direct-positive process, creating a highly detailed image on a sheet of copper plated with a thin coat of silver without the use of a negative. The process required great care. Although daguerreotypes are unique images, they could be copied by redaguerreotyping the original. Copies were also produced by lithography or engraving. Portraits based upon daguerreotypes appeared in popular periodicals and in books.

Daguerre’s Boulevard du Temple could be the first photograph to include a human being. The photo was taken by Daguerre in 1838 in Paris, and it captured a man standing alongside the road. Louis Daguerre achieve the Boulevard du Temple after exposing a chemically treated metal plate for ten minutes. Surprisingly, the person standing alongside the road was not the only person around that time. Other “human beings” were walking or riding in carriages down but they’re were moving so they didn’t show up.

The solar eclipse of July 28, 1851 is the first correctly exposed photograph of a solar eclipse, using the daguerreotype process

Watch below the YouTube Video showing many daguerreotypes.







Some Reports gives some clue about the reason behind showing this Doodle Today.

Speaking of cameras, Google is selling a new smartphone today in United Kingdom which features a five-megapixel back camera with zero-shutter lag, the Samsung Google Galaxy Nexus which features the newest version of Android’s operating system, the Ice Cream Sandwich. Coincidence? Well, maybe.

What do you think about this Doodle? Just Coincidence or Google's Business Tactics?

Under her direction, the world's first studies were conducted into the treatment of neoplasms, using radioactive isotopes. She founded the Curie Institutes.

Marie Curie

 During World War I, Curie helped set up mobile field hospitals that featured primitive X-ray equipment to help detect shrapnel in soldiers.


Curie helped forever change not only how science thought about radioactivity, but also how the world perceived women in science.
