Both bombs caused widespread death, injury, and destruction, and there is still considerable debate about the need to have used them.
Atomic bombs were subsequently developed by the USSR (1949; now Russia), Great Britain (1952), France (1960), and China (1964). A number of other nations, particularly India, Pakistan, Israel, and North Korea now have atomic bombs or the capability to produce them; South Africa formerly possessed a small arsenal. The three smaller Soviet successor states that inherited nuclear arsenals (Ukraine, Kazakhstan, and Belarus) relinquished all nuclear warheads, which have been removed to Russia.
Atomic bombs have been designed by students, but their actual construction is a complex industrial process. Practical fissionable nuclei for atomic bombs are the isotopes uranium-235 and plutonium-239, which are capable of undergoing chain reaction" class='external' title="http://www.answers.com/topic/chain reaction. If the mass of the fissionable material exceeds the critical mass (a few pounds), the chain reaction multiplies rapidly into an uncontrollable release of energy. An atomic bomb is detonated by bringing together very rapidly (e.g., by means of a chemical explosive) two subcritical masses of fissionable material, the combined mass exceeding the critical mass. An atomic bomb explosion produces, in addition to the shock wave accompanying any explosion, intense neutron and gamma radiation, both of which are very damaging to living tissue. The neighborhood of the explosion becomes contaminated with radioactive fission products. Some radioactive products are borne into the upper atmosphere as dust or gas and may subsequently be deposited partially decayed as radioactive fallout" class='external' title="http://www.answers.com/topic/fallout far from the site of the explosion.

Why was the theory of relativity invented?
It was invented when Albert Einstein realized that Universal Gravitation was incorrect. He realized that he needed to propose a theory which would resolve this problem. When Einstein completed Special Relativity, he formulated that nothing travel faster than the speed of light. However, Newtonian Gravitation stated that Gravity was an instantaneous force, therefore this was problematic. Thus Einstein worked on General Relativity to resolve this query by introducing spacetime distortion which result in the gravitational waves that travel at the speed of light.
Ware did albert Einstein came up with the photoelectric effect?
Albert Einstein developed the theory of the photoelectric effect while working as a patent examiner in Bern, Switzerland in 1905. He proposed that light could be understood as consisting of particles called photons that interact with matter. This theory helped to explain certain behaviors of light that could not be explained by classical physics.
When did Albert Einstein propose the theory of relativity?
Special Relativity 1905
General Relativity completed 1915 published 1916
Was there a girl helping Albert Einstein with atomic Bomb?
Albert Einstein did not make the atomic bomb. Einstein himself did not even play a role in the development of the atomic bomb other than signing the letter to get Roosevelt to approve the making of it. He did help the United States Navy with some unrelated theoretical questions it was working on during the war. And girls wouldn't be smart enough. JK. But not really. Ok really.
What if albert Einstein had died before developing nuclear physics?
If Albert Einstein had died before developing nuclear physics, it may have taken longer for advancements in the field to occur. Other scientists and researchers were also working on nuclear physics during that time, so eventually progress would likely have been made, but perhaps at a slower pace without Einstein's contributions.
How did Albert Einstein come up the theory of relativity?
Albert Einstein developed the theory of relativity by questioning the fundamental assumptions of classical physics and incorporating new insights on the nature of space, time, and gravity. He used thought experiments and mathematical reasoning to derive the principles of special and general relativity, which revolutionized our understanding of the universe.
What did Einstein show about matter and energy?
Einstein's famous equation, E=mc^2, shows that matter and energy are interchangeable and can be transformed into each other. This groundbreaking concept paved the way for understanding nuclear energy and revolutionized our understanding of the relationship between matter and energy in the universe.
Who is the develpoer of the theory of relativity?
Albert Einstein is the developer of the theory of relativity. His groundbreaking work consisted of two theories: the special theory of relativity, published in 1905, and the general theory of relativity, published in 1915.
What were some of Albert Einstein's discoveries?
Albert Einstein discovered the Theory of Relativity, he stated that speed of light in a vacuum is constant and an absolute physical boundary for motion.
General relativity was Einstein's major work, and often considered one of the greatest of all time. It was not a discovery so much as an invention; it built upon the work he and others had already advanced in special relativity.
He also discovered the law of photoelectric effect. Calculating size of molecules for which he got doctrate.
When did elbert Einstein get his Ph.D?
Albert Einstein received his Ph.D. in 1905 from the University of Zurich in Switzerland.
No, Albert Einstein was not deaf. He is known to have had hearing loss later in life, but he was not deaf.
Where did Albert Einstein discover the special theory of relativity?
Albert Einstein discovered the special theory of relativity in Bern, Switzerland while working as a patent clerk in 1905.
What was Albert Einstein scared of?
I don't know if he was SCARED but he was against development of weapons. His fellow scientist developed a poisonious gas to use as a weapon in World War 1. He and 4 other scientiest opped this but there were 93 who were for this work to help their country win the war.
Some people think that his discoveries were useless, and that he was just a phsycho with spiky, white hair. Basically he discovered random theories, like the law of relativity. When he died I read that he was planning on making a time machine. Anyway I'm not sure if that's true. But I guess he was super random. A few people said that it is an offence to call someone Einstein 'cos they thought he was stupid. I don't exactly think so, but I only know of a handful of things that he discovered.

How to be a theoretical physicist?
To become a theoretical physicist, you typically need to earn a Ph.D. in theoretical physics or a related field. This involves rigorous study of physics principles, mathematics, and research in theoretical physics. It's also helpful to gain research experience through internships or assistantships, and to stay updated on advancements in the field.
How did Einstein become Einstein?
Einstein developed his groundbreaking theories by questioning existing beliefs, conducting thought experiments, and rigorously studying physics. His creativity, curiosity, and ability to think outside conventional boundaries led to his scientific achievements and reputation as a genius in his field.
Can you teach a snail quantum physics?
No, snails do not have the cognitive capacity to understand complex concepts like quantum physics. Their brain structure is not equipped for such high-level thinking.
What was Albert Einstein's theory?
Albert Einstein's theory of relativity includes two parts: the special theory of relativity and the general theory of relativity. The special theory explains how time, space, and mass are interlinked, while the general theory extends these ideas to include the force of gravity and how it affects the curvature of space-time.
What does Einstein's theory of relativity tell us about energy?
Einstein's theory of relativity, specifically the famous equation E=mc^2, tells us that mass and energy are interchangeable. This means that energy can be converted into mass and vice versa, highlighting the close relationship between the two fundamental concepts.
What do you call a scientist who studies cells?
Cytologist
Cytologists.
A cytologist.
A person who studies cells is a cellular biologist, studying a few differentiated cells of a larger organism. ANOTHER VIEW In biology, cytology is the study of the structure of all normal and abnormal components of cells and the changes, movements, and transformations of such components. The discipline includes cytogenics, cytochemistry, and microscopic anatomy, which involve investigations employing various microscopes, such as light, phase, interference, and electron microscopes. Cells are studied directly in the living state (phase microscopy) or are killed (fixed) and prepared for viewing (embedded, sectioned, and stained) on light or electron microscopes. The specialist in this field of cytology or cell study is called cytologist
