James Griffiths - Shockwave of an exploding star seen for the first time

By Dilip -
It lasted only 20 minutes and took place 1.2 billion light years away, but NASA managed to catch it on camera: a star exploding. The brilliant flash of an exploding star's shockwave -- or "shock breakout" -- has been captured for the first time in visible light by the Kepler space telescope. An international team of researchers analyzed some 50 trillion stars photographed by Kepler over a three-year period, searching for supernovae.

A supernova occurs at the end of a massive star's life, as a colossal, catastrophic explosion erupts, causing the star to burn brighter than some galaxies for around two weeks before fading to black.

The team analyzing the Kepler data found exactly what they were looking for: a red supergiant 500 times the size of our sun and around 1.2 billion light years away exploded while in the telescope's view. Lead researcher Peter Garnavich, an astrophysics professor at the University of Notre Dame, said in a statement that the star is so colossal that "Earth's orbit around the sun would fit comfortably within (it)."

Third degree torture used on Maruti workers: Rights body

By Dilip -
The People’s Union for Democratic Rights on Tuesday alleged that third degree torture methods were used by the Gurgaon Criminal Investigation Agency while interrogating workers of Maruti Suzuki India Limited’s Manesar plant who are accused of involvement in the killing of an HR manager and the violent attack at the plant on July 18. The PUDR alleged that the Gurgaon CIA investigation “did not seem” to be directed at solving the crime or probing the involvement of the arrested workers in the incidents and crimes recorded in the FIR but instead was based on their involvement in trade union activities. Grave doubts  “The use of third degree torture in police custody, and the securing of arrestees’ signatures on blank papers by the police, gives rise to grave doubts regarding the ability of such an investigation in effectively identifying or arresting those guilty. The police and the State seem keener to reassure Maruti Suzuki Ltd. and ensure that production continues,” the PUDR stat

Haruki Murakami: On seeing the 100% perfect girl one beautiful April morning

By Dilip -
According to Murakami, “1Q84” is just an amplification of one of his most popular short stories,   which (in its English version) is five pages long. “Basically, it’s the same,” he told me. “A boy meets a girl. They have separated and are looking for each other. It’s a simple story. I just made it long.” One beautiful April morning, on a narrow side street in Tokyo's fashionable Harujuku neighborhood, I walked past the 100% perfect girl. Tell you the truth, she's not that good-looking. She doesn't stand out in any way. Her clothes are nothing special. The back of her hair is still bent out of shape from sleep. She isn't young, either - must be near thirty, not even close to a "girl," properly speaking. But still, I know from fifty yards away: She's the 100% perfect girl for me. The moment I see her, there's a rumbling in my chest, and my mouth is as dry as a desert..." read the story: http://www.youmightfindyourself.com/post/22131227

The Almond Trees by Albert Camus (1940)

'Do you know', Napoleon once said to Fontanes, 'what astounds me most about the world?  The impotence of force to establish anything.  There are only two powers in the world: the sword and the mind.  In the end, the sword is always conquered by the mind' Conquerors, you see, are sometimes melancholy.  They have to pay some price for so much vainglory. But what a hundred years ago was true of the sword is no longer true today of the tank. Conquerors have made progress, and the dismal silence of places without intelligence has been established for years at a time in a lacerated Europe. At the time of the hideous wars of Flanders, Dutch painters could still perhaps paint the cockerels in their farmyards. The Hundred Years War has likewise been forgotten, and yet the prayers of Silesian mystics still linger in some hearts. But today, things have changed; the painter and the monk have been drafted - we are one with the world.  The mind has lost that regal certainty which a c

Albert Camus's lecture 'The Human Crisis', New York, March 1946. 'No cause justifies the murder of innocents'

By Dilip -
The morning after a great historical crisis, you feel as sad and sick as after a heavy night. But there is no aspirin for historical hangovers .. The world is no longer divided into the just or unjust, but into masters and slaves. He who is right is he who enslaves.  Albert Camus     La crise de l'homme : THE HUMAN CRISIS   (Text read by Viggo Mortensen on March 28 2016)   Ladies and Gentlemen: when I was invited to give a series of lectures in the United States of America, I felt some doubt and hesitation. I am really not old enough to give lectures, and I am more at ease with the process of thinking than I am making categorical statements... since I don't feel I have any claim on what is generally called the truth. I shared this reservation and was very politely told that my personal opinion didn't matter. What mattered was that I'd be able to offer some facts about France so that my listeners could form their own opinions. It was then suggested that I might

After the Truth Shower

By Dilip -
Dear Readers Thank you for reading my blog for the past eleven years. (This is a link to the new one) During this time it has had nearly 1.7 million hits; and I have posted over 9500 posts covering a variety of themes. From July 11 to 19, 2022, my blog was withdrawn by the Blogger administration on account of what its machinery suspected to be 'Impersonation'. It took over a week and the efforts of several well-wishers to get it back online I thank them all for their kindness and goodwill  My blog has always been - and remains - non-commercial. I have used it for academic purposes; and to foster a culture of debate and informed commentary in civil society. Because it contains a large amount of material gathered and collated for over a decade, I cannot afford to lose its contents. I hope it will remain undisturbed now and function as an archive. However, I have decided to use a new blog on WordPress as a platform for my newest comments and posts The new blog is titled After the

Rudyard Kipling: critical essay by George Orwell (1942)

By Dilip -
Mother of Cities to me, For I was born in her gate, Between the palms and the sea, Where the world-end steamers wait  Rudyard Kipling , To the City of Bombay "Few people who have criticized England from the inside have said bitterer things about her than this gutter patriot" : George Orwell IT WAS a pity that Mr. Eliot should be so much on the defensive in the long essay with which he prefaces this selection of Kipling's poetry, but it was not to be avoided, because before one can even speak about Kipling one has to clear away a legend that has been created by two sets of people who have not read his works. Kipling is in the peculiar position of having been a byword for fifty years. During five literary generations every enlightened person has despised him, and at the end of that time nine-tenths of those enlightened persons are forgotten and Kipling is in some sense still there. Mr. Eliot never satisfactorily explains this fact, because in answering the shal
