“Manhattan Project: Detonate of the first Atomic Bomb”
The time was 5:29 a.m., July 16, 1945 and out in the middle of the Jornada del Muerto desert which was about 35 miles away from the nearest town, Socorro, New Mexico, the United States ---for the first the human history --- unleashed the power of nuclear weapons. The detonation of the “Trinity” bomb release around 84 TJ which is equivalent to around 20 kilotons of TNT that created a massive crater at the ground zero bomb test. Those who had observed the detonation described as a “ball of fire” as if the “sun was coming up in the south”.
At that time, the code name for first nuclear test was Trinity. With the goal of beating the Germans to the development of nuclear weapons, the US recruited Julius Robert Oppenheimer, the director of the Los Alamos Laboratory, to spearhead efforts to develop the first nuclear weapon arsenal to

Earlier on, dating back to the Romans, glass was used to magnify objects for easy viewing and by the 13th century the first glass eyepiece was invented by the Italian inventor Salvino D'Armate. Through the years, methods were developed to created magnifications up to 3x-5x. These primitive lens were frequently used during examination of tiny insects such as ants or fleas.
It was then during the 1950’s that Zacharias Jansen and his father, Han Jansen, created the first high-powered compound light microscope. Images could be magnified up to 9x which was a novel feat at that time. Zacharias and his father created the device after experimenting with glasses and discovered that by placing multiple lens in a tube they could increase magnification. Unfortunately, the microscope lacked the high resolution we have come to expect in modern-day light microscopes. The images produced by the Hans’ primitive microscope was extremely blurry and had limited
The illuminating parts of a microscope enable us to see the detail of the subject placed under the microscope. The three main parts that enable us to do this are: the condenser which illuminates the object that is placed under the microscope, the objectives which forms the magnified image, and the eyepiece which enables us to see the magnified
Concept 6.1 Biologists use microscopes and the tools of biochemistry to study cells 1. The study of cells has been limited by their small size, and so they were not seen and described until 1665, when Robert Hooke first looked at dead cells from an oak tree. His contemporary, Anton van Leeuwenhoek, crafted lenses and with the improvements in optical aids, a new world was opened. Magnification and resolving power limit what can be seen. Explain the difference. Magnification is the ratio of an object’s image size to its real size. Resolution is a measure of the clarity of the image; it is the minimum distance two points can be separated and still be distinguished
After six months of the United States attacking Japanese cities using bombs with the United Kingdom, and China, and the Japanese go as far as to use suicide bombers to change the events of the war, the United States called for japan to surrender. But the Japanese government was too honorable to surrender in time of war and ignored the Potsdam Declaration. Created by brilliant scientists, the bomb which was Original’s purpose was to be used against Nazi Germany was to be used to end the war. The bomb which could wipe a city off the surface of the map and cause long time damage was first atomic test was in New Mexico which Exploded with the force of 67 million sticks of dynamite. The flash from the explosion could be seen from over 10 miles away
An article written by Khan academy lays out the events leading up to the detonation of the atomic bombs. The article gives information on the Manhattan Project, which was the codename for the US government. Khan academy also writes about how the atomic bomb was built as well as how the atomic bombs ended WWII.
With the new working bomb, during World War II American B-29 bomber dropped the world’s first atomic bomb called the little boy weighing 9,000 pounds on Hiroshima, Japan instantly killing eighty-thousand people then killing over tens of thousands of people after due to radiation exposure. Three days later another bomb
When thinking about the magnifying properties of lenses, I had never known what properties the glass must have to magnify something. And when I thought about how the science of it came about, I imagined some great mathematician performing calculus to evaluate the curve of the lens. Instead, van Leeuwenhoek heated glass rods and pulled them apart, each time finding new properties that explained the magnification levels of the lens. He created lenses so strong that he could examine microorganisms taken from the teeth of another person (pg. 86). Because I had initially assumed there was a great process to making a lens, I have become ever-curious to know what made him think simply pulling glass apart would affect its magnification properties. Additionally, did he know the extent to which he revolutionized science? I’m also now curious to know how we create lenses
“We believe that . . . an early unannounced attack against Japan inadvisable. If the United States were to be the first to release this new means of indiscriminate destruction upon mankind, she would sacrifice public support throughout the world, precipitate the race for armaments, and prejudice the possibility of reaching an international agreement on the future control of such weapons. Much more favorable conditions could be created if nuclear bombs were first revealed to the world by a demonstration in an appropriately selected uninhabited area.” The initial test for the atomic bomb was dropped in Alamogordo, Mexico with experts observing more than 20 miles away. The explosion was estimated to be a blast of about 10,000 tons of TNT. The Atomic bomb’s intense and destructive power frightened many scientists who were working on the Manhattan Project (Knebel 78). Including the father of the atomic bomb, J. Robert Oppenheimer. Oppenheimer felt as if he had created something that would bring forth destruction to the world, instead of using his brilliant scientific mind to improve and usher the world into an era of peace like he intended to. In fact, many scientists within the Manhattan Project were shocked and against using such a powerful weapon as the atomic bomb against other humans, so much that a group of scientists and
The United States dropped their first atomic bomb over the Japanese city of Hiroshima on August 6th, 1945. The explosion was tragic, “90 percent of the city was wiped out and immediately killed 80,000 people; tens and thousand more would later die to radiation exposure” (Lemay and Paul). Innocent children and citizens would die.
“We have to protect our Earth, so our children and grandchildren will never suffer like that,’ she said. And she looked ahead. ‘Maybe nuclear weapons won’t be abolished while I’m alive,’ she said. ‘But I will never give up.” (Hanley, NBC News). August 6, 1945 at 8:16 in the morning, the United States dropped the world's first atomic bomb on thousands of unsuspecting people in Hiroshima, Japan. Not only did this catastrophic event kill thousands of civilians, but it also resulted in other nations obtaining and learning how to create these deadly weapons, weapons that we still have today. In the book Hiroshima by John Hersey he gives readers a new look at that day, through the eyes of six victims who survived the horrific attack on Hiroshima, he shows how the entire city of Hiroshima suffered, and were left alone to fend for themselves.The book Hiroshima by John Hersey, sheds light on the immense dangers of nuclear warfare, and the government's responsibility for its people, affected by a war they aren’t fighting in.
Finally, the bombing of Hiroshima and Nagasaki was unjustified because of the lack of testing. Although the project to design the first atomic bomb, codenamed the Manhattan Project, began in 1941, the first bomb was not ready to be tested until the month before it would be used in 1945. When it was tested at Trinity Site in New Mexico, the detonation caused unexpected results (“The Manhattan Project”). It caused “A blinding flash visible for 200 miles lit up the morning sky. A mushroom cloud reached 40,000 feet, blowing out windows of civilian homes up to 100 miles away. When the cloud returned to earth it created a half-mile wide crater metamorphosing sand into glass” (“The
The bomb exploded with the power of 22,000 tons of TNT and 70,000 people died in 1945 from the bomb.
On July 16, 1945, the Nuclear Bomb had went off; changing the world forever. Although the explosion lasted less than a minute, the process to get there was tedious and left a taint mark in Los Alamos, New Mexico.
The first test of a fission bomb was done on Monday, July 16, 1945, in the Jornada del Muerto desert in New Mexico, at 5:29:45 A.M., Mountain War Time. This was the test of a plutonium bomb that was given the code name Trinity. The need to avoid sending more ground troops further into Japan was a priority because it was becoming clear that the Japanese forces were fighting more fiercely the closer American forces got to the home islands. Invading and seizing Japanese territories was not easily accomplished because of the 1941 Code of the Japanese Soldier that required victory or death. Hence, the public became aware of the true story about what the bright light and tremor of shock waves that encompassed a 160-mile radius of the Trinity test site truly was when President Harry S. Truman ordered the drop of its second nuclear bomb that detonated over Hiroshima, Japan on August 6, 1945. The second nuclear bomb was the second design that the LAL, under the direction of Oppenheimer, had been working on. The
The citizens of Hiroshima, Japan awoke on August 6, 1945 to a seemingly normal, bustling day within the city. However, sirens blasted throughout the streets at seven in the morning, provoking citizens to take shelter within their safe spots. The world was at war and the threat of the enemy could have closed in at any minute. A wave of relief washed over their souls when the all-clear signal rang over the intercoms. However, they knew little about what was in store for their futures. An hour and fifteen minutes later, a tremendous flash of lightning covered the city and instantaneously blinded people. The flame of light shone brighter than the sun, leaving the city covered in white ash with shadows of figures painting the grounds. The United States had just attacked the city of Hiroshima with the deadliest weapon known in warfare and one that had never been used in combat throughout all of history: the atomic bomb. The use of the atomic bomb not only changed warfare for the rest of time, but also changed the lives of both Japanese and American citizens for decades to come.
Most microscopes, including those in schools and laboratories today, are optical microscopes. They use glass lenses to enlarge, or magnify, an image. An optical microscope cannot produce an image of an object smaller than the length of the light wave in use. To see anything smaller than 2,000 angstroms (about 1/250,000 of an inch) a wave of shorter length would
