Cropped from the running reel of a motion picture camera, a black and white frame shows a rapidly forming mushroom cloud bellowing tons of gas and debris, milliseconds after the Trinity Gadget was detonated in a secluded location of the present-day White Sands Missile Base on the 16th of July in 1945.
How the Mushroom cloud forms.
One of the most widely recognized stages of an atomic explosion for its propensity to remain visible longer, the mushroom cloud, however, is the last stage of a high-speed sequence.
A sequence that begins when the intense energy of an atomic fireball super heats the air within its sphere and causes it to rise rapidly, and which in turn creates an empty void in the centre that sucks in the surrounding cooler air, along with earth and debris.
This part of the sequence lasts till the atomic energy lasts and builds up into a powerful vortex in which heated air continuously punches upwards at the centre while at the fringes cooler air plummets down.
Upon reaching a certain height, the sucked in earth and derbies from the surroundings are pushed outwards towards the fringes and which along with the cooler air spiral downs to the ground, pulled by the earth’s gravity.
In the process it forms into a frothy cloud of highly radioactive gas, heated air and neurons.
Once this frothy cloud reaches the stratosphere and comes in contact with the ozone layer, heated by solarization and almost equal in temperature. It stops its horizontal ascent and begins to spread out laterally to form the familiar shape of a mushroom cloud.
Though initially reddish-brown in colour, the cloud speedily turns white as rapid condensation occurs and nitrogen oxide is replaced by water droplets. The formation of the cloud largely depends on the distance between the explosion and the ground.
If the explosion takes place high up in the air, there is less chances of a mushroom cloud forming. If on water, the cloud produced takes the shape of a cauliflower, and if detonated underground, it forms a crater.
Robert Oppenheimer’s reaction upon witnessing the first atomic explosion.
On the 16th of July in 1945, as scientists, soldiers and technicians involved in producing the atomic explosion had gazed upon this phenomenal sight for the first time in history, though the moment had been one of celebration and rejoicing, it had, however, produced a mixed reaction from the men and women who had struggled almost three years to bring the atomic project to fruition under tremendous pressure.
To Robert J. Oppenheimer, the man credited to be the father of the atomic age, the sight had reminded him of a phrase from the Bhagwat Gita – an ancient compilation of philosophies produced by Vedic Aryan poets, aeons before the birth of the atomic bomb.
A scholar with a philosophical bent of mind who had preferred to discuss philosophy with his colleagues even while at work, Oppenheimer expressed his sentiments on that day, as quoted below:
I remembered the line from the Hindu scripture, the Bhagwat Gita: Vishnu is trying to persuade the prince (Arjuna) that he should do his duty and to impress him he takes on his multi-armed form and says, “Now I am death, the destroyer of worlds”. I suppose we all thought that one way or another.
Robert J. Oppenheimer , Trinity Test, 1945.
The underlying message in the phrase.
The phrase Oppenheimer made famous in the Western World, comes from a chapter of the Gita, titled the vision of the universal form. Its underlying message is that whatever happens in the universe has already been decreed by God and man simply needs to play the part he was born for.
In the epic poem Mahabharata, of which the Gita is an integral part, this discourse takes place at the beginning of the mythical battle of Kurukshetra, and is presented as a dialogue between the prince Arjuna and Krishna.
The prince Arjuna, who is a protagonist of the epic poem, refuses to fight upon seeing that his opponents are none other than his cousins, friends and elders. Krishna, his friend and charioteer, encourages him to carry out his solemn duties by first revealing his frightening multi-armed cosmic form, radiant and blinding to behold, and then with the following words, that is mentioned below.
I am the terrible time. The destroyer of all beings in all worlds and presently engaged in destroying all beings in this world. Those mighty soldiers that you see before you, even without your participation, none will survive, for I have decreed so.
The phrase is also and popularly quoted as:
If the radiance of a thousand suns were to at once burst upon the sky that would be the radiance of the mighty one…now I am become death, the destroyer of worlds.
The Bhagwat Gita
Robert Oppenheimer’s fascination with eastern philosophy.
Although Oppenheimer was born of German-Jewish parentage and was a physicist, he nonetheless had harboured a deep fascination for eastern philosophy. While still a student at the University of Gottingen in Germany, he had mastered the difficult language of Sanskrit to read and comprehend this ancient philosophy.
As the man responsible for spearheading the atomic project, it is quite possible Oppenheimer at the time was troubled by his conscience. Oppenheimer and all others responsible for inventing the atomic bomb were fully aware of its intended purpose, yet at that precise moment were awestruck with they had just witnessed, perhaps deep down even elated.
Hiroshima and Nagasaki, cities chosen by fate.
Though the atom bombs were eventually released over the cities of Hiroshima and Nagasaki in Japan, they had been essentially developed to be used against Nazi Germany.
Many of the scientists responsible for producing the atomic bomb, like Robert Oppenheimer, were Jewish in faith and against Hitler’s anti-Jewish laws – and which had unleashed a genocidal event in which millions of Jews were systematically murdered.
The mushroom cloud that had formed on this day had towered almost 39,600 feet in height, for the amount of plutonium used and which was equal to 22 kilotons of TNT.
The plutonium was stored inside the experimental container known as the Trinity Gadget.
During the test, this container was dropped from the top of a 100 feet high reinforced steel tower to mimic the conditions that would be produced when the actual bombs were released from the bomb bays of the B-29 bombers assigned for the task.
The nuclear fallout.
The explosion was felt not only in the state of New Mexico but also in three other neighbouring states. While the subsequent nuclear fallout was later discovered to have affected an even wider area.
An Eastman Kodak Factory located some 2,000 miles away at Rochester in New York, had reported of spots mysteriously appearing on its sensitive x-ray films, and which was later learnt to be from radiation.
The name Trinity, in Trinity Test Site.
The name Trinity is believed to have been given by Robert Oppenheimer. With the inspiration sometimes stated to have come from a holy sonnet Oppenheimer was reading during the development of the atomic bombs. Other times, it is said to come from the Vedic concept of the three supreme gods of Brahma, Vishnu and Shiva.
Out of the two speculated sources, the 14th Holy Sonnet by the poet John Donne is more widely accepted to have inspired the code name of the nuclear test site.
This black and white frame was produced by one of the 52 motion picture cameras, photographer cum cinematographer Berlyn Brixner, had strategically placed around the test site to film and document the event.
It is now is archived by theNational Archives and Records Administration.
