the most distinguished and celebrated American authors of the 20th and
21st century. He was an essayist, poet, novelist, playwright, short
story writer and screenwriter, renowned for his writings in genres like
horror, fantasy, mystery fiction and science fiction. Though he received
recognition as a bold writer with a vision for his science fiction,
‘The Martian Chronicles’, he shot to fame with his masterpiece,
‘Fahrenheit 451’, a dystopian novel considered to be his best work. His
other notable works include ‘The Illustrated Man’, ‘There Will Come Soft
Rains’, ‘The October Country’ and ‘Quicker Than the Eye’. His body of
works include around six hundred short stories, thirty books, several
plays, poems and essays. Four ‘Best American Short Story’ anthologies
include his works. His creative visions were not only limited to his
writings. He hosted the ‘Ray Bradbury Theater’, created the interior
metaphors at ‘Epcot's’ ‘Spaceship Earth’ in the ‘Disney World’ and
served ‘United States Pavilion’ as creative consultant during ‘New York
World's Fair’. His animated film ‘Icarus Montgolfier Wright’ earned him a
nomination for the ‘Academy Awards’ while his 1993 teleplay ‘The
Halloween Tree’ (adapted from his 1972 novel) earned him an ‘Emmy Award’
in 1994.
Childhood & Early Life
He
was born on August 22, 1920, in Waukegan, Illinois, to Leonard
Spaulding Bradbury and Ester Moberg Bradbury. His father was a lineman
for telephone and power utilities.

World Photography Day & World Humanitarian Day
World Photography Day is an international photography event on August 19th that celebrates the passion for photography in our communities.
In a world where millions of pictures are uploaded every minute, World
Photo Day is inspiring thousands of photographers across the planet to
share a single photo with a simple purpose: to share their world with the world.
From everyday life to incredible landscapes, our global gallery is an
evolving mosaic of images captured by photographers of all skills levels
living in a diverse range of countries and cultures.
No matter who you are, where you are or what equipment and skills you
have, World Photo Day can help open your eyes to the possibilities of
photography, and enable you show us the world as you see it.
August
19 is observed as World Photography Day, which aims to inspire
photographers across the planet to share a single photo with a simple
purpose: to share their world with the world. Here is a look at
photography over the years.
World Photo Day originates from the invention of the Daguerreotype, a photographic process developed by Frenchmen Louis Daguerre and Joseph Nicephore Niepce in 1837.
On January 9, 1839, the French Academy of Sciences announced the Daguerreoty ..

World Humanitarian Day
The
United Nations’ (UN) World Humanitarian Day is held on August 19 each
year. The day honors all humanitarians who have worked in the promotion
of the humanitarian cause, and those who have lost their lives in the
cause of duty. It aims to increase public awareness about humanitarian
assistance activities worldwide and the importance of international
cooperation.
What Do People Do?
World Humanitarian Day is a day dedicated to humanitarians worldwide,
as well as to increase public understanding of humanitarian assistance
activities. The day aims to honor humanitarian workers who have lost
their lives or injured themselves in the course of their work, and to
acknowledge the ongoing work of humanitarian staff around the world.
Many communities and organizations try to increase the importance of
humanitarians by distributing publicity and information material.
Additionally, some try to speak to the press to help spread these key
messages of World Humanitarian Day, while other groups organize public
events worldwide that feature humanitarian work.
For the year 2010 and beyond, it is anticipated that World
Humanitarian Day will focus on particular humanitarian themes to help
increase public awareness.
Background
Humanitarians provide life-saving assistance to millions of people
worldwide. They place their own lives at risk to help others in conflict
zones and areas of natural hazards. More than 700 humanitarian workers
have died or experienced the most dangerous situations while trying to
help those in need. Humanitarians provide support for different world
challenges such as hunger, gender-based violence, refugees and displaced
people, help for children, as well as clean water and access to
sanitation.
World Humanitarian Day was established by the General Assembly of the
UN in December 2008 and was first observed in August 2009. The date of
August 19 is the anniversary date of the 2003 Canal Hotel bombing in
Baghdad where twenty-two people lost their lives including, the UN’s
High Commissioner for Human Rights and the Special Representative of the
Secretary-General to Iraq, Sergio Vieira de Mello.
The total number of people affected by natural disasters has risen
over the past decade, and about 211 million people are directly affected
each year. Women and children are especially affected because of their
ongoing struggles with poverty, insecurity, hunger, poor health and
environmental decline. There are new and difficult challenges that arise
each year that will require more flexible funding and adaptable
humanitarian work. The increasing economic crisis and global challenges
such as poverty, global health problems, increase prices and the rising
number of people on the move, increases the need for humanitarians each
year.

Librarians Day in India
12th August is Celebrated as National Librarian’s Day in India
Dr. S R Ranganathan (1892-1972)
Ranganathan, born on 9 August 1892, came from a moderate background in British-ruled India. He was born in the small town of Shiyali (now known as Sirkazhi), in the state of Tamil Nadu in southern India.
Ranganathan began his professional life as a mathematician; he earned B.A. and M.A. degrees in mathematics from Madras Christian College in his home province, and then went on to earn a teaching license. His lifelong goal was to teach mathematics, and he was successively a member of the mathematics faculties at universities in Mangalore, Coimbatore and Madras (all within the span of five years). As a mathematics professor, he published a handful of papers, mostly on the history of mathematics. His career as an educator was somewhat hindered by a handicap of stammering (a difficulty Ranganathan gradually overcame in his professional life). The Government of India awarded Padmashri to Dr. S.R. Ranganathan for valuable contributions to Library Science.
Five Laws of Library Science:
• Books are for use
• Every reader his/her book
• Every book, its reader
• Save the time of the reader
• A library is a growing organism
August 12th is being celebrated as National Librarian’s Day in India, in remembrance of national professor of library science, Dr S R Ranganathan (1892-1972), who had spearheaded library development in India.

Son and Daughter Day
August 11 is Son and Daughter Day, a day for parents to show their love and appreciation for their children.
While the origins of this unofficial holiday are a mystery, it is
clear that the anonymous creators Son and Daughter Day wanted parents to
acknowledge the joy their children bring into their lives.
The bond between parents and their sons and daughters is a very
special one. It endures age and distance. No matter how old a person
gets, their parents still see him or her as a child - someone to protect
and shower love on. So, take this day to tell your sons and daughters
how much they mean to you and that you respect them and love them.
How to Celebrate?
- If you have young kids, take them out for a fun outing to let them know that you care about them.
- Give your kids a big hug in the morning and tell them how much you love them.
- Make them a special meal and let them eat treats reserved for special days.
- Don’t have kids? Shower your affection on your nieces or nephews if you have any. If you don’t, what about making it a special day for your pet? After all, they are like your kids, no?
Did You Know...
...that the concept of childhood as a phase in life where children
need the protection and nurturing of their parents and other adults came
about in the 16th century? Before this, children were seen as miniature
and incomplete version of adults.

International Day of World’s Indigenous People, Quit India Day, Nagasaki Peace Day & National Book Lovers Day
Book Lover's Day is observed on August 09, 2016.
It's a day for those who love to read. Just take a great book and relax
by reading it. Bibliophilia or bibliophilism is the love of books.
Accordingly a bibliophile is an individual who loves books. A bookworm
is someone who loves books for their content, or who otherwise loves
reading. A bibliophile may be, but is not necessarily, a book collector.
This text has been taken from
The United Nations’ (UN) International Day of the World's Indigenous
People is observed on August 9 each year to promote and protect the
rights of the world’s indigenous population. This event also recognizes
the achievements and contributions that indigenous people make to
improve world issues such as environmental protection.
Quit India Movement was one of the significant movements towards
achieving freedom. The history of Quit India Day is written in golden
letters in India's freedom struggle. It is one of the crucial movements
in India's freedom struggle. The movement was the brainchild of Mahatma
Gandhi. He urged the whole country to raise their voice against the
suppressing British Raj. This led to the Quit India Movement.
On this day in 1945, a second atom bomb is dropped on Japan by the
United States, at Nagasaki, resulting finally in Japan’s unconditional
surrender.
The devastation wrought at Hiroshima was not sufficient to convince
the Japanese War Council to accept the Potsdam Conference’s demand for
unconditional surrender. The United States had already planned to drop
their second atom bomb, nicknamed “Fat Man,” on August 11 in the event
of such recalcitrance, but bad weather expected for that day pushed the
date up to August 9th. So at 1:56 a.m., a specially adapted B-29 bomber,
called “Bock’s Car,” after its usual commander, Frederick Bock, took
off from Tinian Island under the command of Maj. Charles W. Sweeney.
Nagasaki was a shipbuilding center, the very industry intended for
destruction. The bomb was dropped at 11:02 a.m., 1,650 feet above the
city. The explosion unleashed the equivalent force of 22,000 tons of
TNT. The hills that surrounded the city did a better job of containing
the destructive force, but the number killed is estimated at anywhere
between 60,000 and 80,000 (exact figures are impossible, the blast
having obliterated bodies and disintegrated records).

Scientist of the day - William Rowan Hamilton
(04 August 1805 - 02 September 1865)
One of the most significant Irish scientists, William Rowan Hamilton
made noteworthy contributions in the field of classical mechanics,
algebra and optics. What is interesting to note is that Hamilton, from
the tender age of five, showed signs of making it big in the world. His
immense talent was appropriately nutured right from the very beginning,
which further enhanced his capabilities. While Hamilton is known to have
contributed in various fields, it is his work in the reformulation of
Newtonian mechanics, now called Hamiltonian mechanics, that tops the
list. This work proves to be the foundation of the modern study of
classical field theories such as electromagnetism, and to the
development of quantum mechanics. To know more about this inventor of
quaternions, read through these following lines
Early Life
Fourth of the nine children of Sarah Hutton and
Archibald Hamilton, young William Hamilton was born in Dublin, Ireland.
His father, a solicitor by profession, was mostly touring England
practising legal business. As such, he had little or no time to teach
young Hamilton. It was due to this reason that William Hamilton, at the
age of three, was sent to live with his uncle James Hamilton. A graduate
from the Trinity College, his uncle ran a school in Talbots Castle.
Young Hamilton displayed signs of being a fast learner right from the
very childhood. By the age of five, he had learned three languages
including, Latin, Greek and Hebrew and before 12, he broadened his
knowledge in various other languages, such as Arabic, Sanskrit, Persian,
Syriac, French, and Italian. While until then, languages seemed to be
the only love of Hamilton, it was a meeting with Zerah Colburn that
altered the passion. Colburn, who was a master at mental arithmetic,
competed with Hamilton and emerged as the winner. Not used to being
beaten in any contest of intellect, this defeat sparked in Hamilton an
interest in mathematics and rest as they is history.
Introduction To Mathematics
Hamilton’s formal introduction to mathematics
came the following year, in 1818, when he studied Clairaut’s Algebra.
His mastery over French made it somewhat easier for him to understand
the concept. By the age of fifteen, he started studying the works of
Newton and Laplace. During this time, Hamilton was also involved in
preparations for entrance at the Trinity College, Dublin. At the age of
18, Hamilton found himself a seat at the Trinity College and in his very
first year, acquired ‘optime’ in Classics, a distinction awarded only
once in twenty years. Hamilton submitted his first paper to the Royal
Irish Academy in the year 1824, entitled, On Caustics. His progress
somewhat declined the following year, with him earning grade ‘bene’
instead of the usual ‘value bene’. However, Hamilton soon bucked up and
in 1826, again amazed everyone by bagging an 'optime' in both science
and Classics, a feat unheard of. In the final year as an undergraduate,
Hamilton presented a memoir, Theory of Systems of Rays, to the Royal
Irish Academy. It was in this paper that Hamilton introduced the
characteristic function for optics.
His Trysts
During this time, the post of Andrews
Professorship of Astronomy was vacant in the University of Dublin. Under
the persuasion of Boyton, Hamilton’s finals examiner, the latter
applied for the position, in spite of knowing that already six
applicants had applied for the vacancy. In 1827, a little prior to his
graduation, Hamilton was offered the position of Professor of Astronomy.
This appointment not only meant Hamilton having the honorary title,
Royal Astronomer of Ireland, but also allowing him the benefit of
staying at the Dunsink Observatory. However, this selection invited a
great deal of criticism and controversy, since Hamilton did not have
much experience in the field.
Hamilton’s predecessor, Dr. Brinkley, pointed
out the fact that Hamilton’s decision was incorrect and that he should
have waited for a fellowship. Hamilton’s newest acquisition of the chair
of professorship, however, did not upgrade his level of intellect much.
This was due to the fact that although Hamilton had insightful
knowledge of theoretical astronomy, he had little or no knowledge of the
regular work of the practical astronomers. Also, Hamilton had a belief
that he could do wonders in the field of research than being engaged in
observation. The authorities of the university, however, thought
otherwise. If Hamilton dedicated himself thoroughly to practical
astronomy, they assured to provide him with the best and the most
advanced of instruments and adequate staff members.
His Contributions in Optics & Mechanics
The same year, i.e. in 1827, Hamilton presented a
theory of a single function, now known as Hamilton's principal
function. The theory brought together mechanics, optics and mathematics,
thus helping establish the wave theory of light. The Royal Irish
Academy paper was entitled Theory of Systems of Rays, with the first
part being printed in 1828 in the Transactions of the Royal Irish
Academy. The second and the third part were printed in three voluminous
supplements, which were published in Transactions as well as in the two
papers On a General Method in Dynamics, which appeared in the
Philosophical Transactions in 1834 and 1835. it was in these editions
that Hamilton’s formulation of the concept of “Varying Action” was
mentioned. According to this theory, a single ray of light entering a
biaxial crystal at a certain angle emerged as a hollow cone of rays.
This breakthrough is still known by its original name, "conical
refraction".
One thing that was common in all Hamilton’s
research was that they were, somehow or the other, based on the
principle of “Varying Action”. While the principle is based on the
calculus of variation, it, however, revealed a detailed mathematical
structure than that had been previously understood. Though Hamilton’s
take on classical mechanics is based on the same physical principles of
Newton and Lagrange, it provides a powerful new technique for working
with the equations of motion. Both Lagrangian and Hamiltonian approaches
were initially developed to describe the motion of discrete systems and
have proven to be critical in the study of continuous classical systems
in physics, and even quantum mechanical systems. As such, the
techniques are still in use in electromagnetism, quantum mechanics,
quantum relativity theory, and quantum field theory.
His Contributions in Quaternions
Hamilton’s another greatest contribution in the
field of mathematical science was his discovery of quaternions in 1843.
In this, Hamilton was looking for ways to extend complex numbers to
higher spatial dimensions. While he failed to successfully find a
three-dimensional system, he effectively created the four-dimensional
system, wherein which he created quaternions. Interestingly, Hamilton’s
formulation of the equation came when he was walking with his wife along
the Royal canal. Fearing that he might forget the equation by the time
he got back home, he carved the same into the side of the nearby Broom
Bridge, using his penknife. This marked the discovery of the quaternion
group.
Hamilton described a quaternion as an ordered
four-element multiple of real numbers, and described the first element
as the 'scalar' part, and the remaining three as the 'vector' part. As a
method of analysis, Hamilton introduced both quaternions and
biquaternions, as the extension to eight dimensions by establishment of
complex number coefficients. Hamilton had declared that the quaternions
would play a pivotal role as an instrument of research. During his end
days, Hamilton was working on a definitive statement of quaternion
science. Posthumously, his son published Elements of Quaternions, a
hefty volume of 762 pages, in 1866. Today, the quaternions are used in
computer graphics, control theory, signal processing, and orbital
mechanics, mainly for representing rotations/orientations.
Personal Life
The journey to Summerhill in 1824 along with
uncle James was an important one in the personal life of Hamilton, for
it was there that Hamilton first met Catherine, daughter of the Disney
family, which the two were visiting. Hamilton was instantly struck with
the cupid’s arrow and fell head over heels in love with the lady.
However, since he was too young to propose marriage, he returned without
saying anything. Year 1825’s month of February wasn’t a very favorable
one for Hamilton as it was then that Catherine’s mother broke the news
of Catherine’s marriage to a clergyman. Hamilton was deeply hurt. The
turmoil in his personal life affected his career as well. What’s more,
Hamilton even had suicidal thoughts occurring to him. It was during this
period that Hamilton turned to poetry as a means of letting out his
anguish. Hamilton was so much in love with Catherine that for him, it
did not later matter whom he married. As a result, he tied the nuptial
knot with Helen Maria Bayly who lived just across the fields from the
observatory. The couple had a son named, William Edward Hamilton.
Death & Legacy
A severe attack of gouttook the life of Sir
William Rowan Hamilton on September 2, 1865. This attack was the result
of his excessive drinking and overeating. Hamilton was interred at the
Mount Jerome Cemetery in Dublin. Recognized one amongst Ireland’s
leading scientists, Hamilton is being increasingly celebrated year after
year for his groundbreaking discoveries. For the same, he has been
honored in a number of ways. An applied mathematics research institute,
in the name Hamilton Institute, was formulated at NUI Maynooth in the
year 2001. Ireland’s Royal Irish Academy also holds an annual public
lecture by the name Hamilton lecture at which celebrated scientists from
around the world take part in. The RCSI Hamilton Society was founded in
the year 2004.
Year 2005 marked the 200th anniversary of Sir William
Rowan Hamilton. As such, it was celebrated with great pomp and show.
While the Irish government designated the year as Hamilton Year,
celebrating Irish science, Trinity College Dublin commemorated the
contribution made by this prolific scientist by launching the Hamilton
Mathematics Institute TCD. In the same year, the Central Bank of Ireland
issued a commemorative coin. Numerous concepts and objects in mechanics
have been given the name of Hamilton. The term Hamiltonian stands for
both, a function and an operator in physics. The algebra of quaternions
is mostly denoted by the letter H, to honor the contributions made by
Hamilton.
