There were more bombs ready to be dropped on Japan.  The third was packed up and ready to be shipped to Tinian, but was never shipped.  If I remember correctly there were a total of seven or nine in the inventory by the end of 1945.

Also, there were many people involved in actually building the A-bomb. It was called the Manhattan project.  The project leader was Robert Oppenheimer and there were several other Nobel laureate physicists working on the project, including Ernest Lawerence and Edward Teller.  Albert Einstein was NOT one of them, and he had almost nothing to do with the theory and application of nuclear fission.

Einstein gets credit for writing the famous letter to Roosevelt, where he said an atom bomb could be built, so that the US should do it first. Even here, he was coached by Edward Teller, and one other.

I think Roosevelt should really get the credit for building the bomb. In an interview that Teller gave, he said it was Roosevelt's powerful speech one day to a group of scientists that convinced him to leave basic research for weapon's research. Roosevelt said that the future of the free world depended on them.  After WWI, most of the scientific team Oppenheimer had assembled, dispersed, refusing to do any more weapon's research. Teller believed that with the Stalinistic threat, the hydrogen bomb had to be pursued.

There was a team that developed the bomb, Einstein, Oppenheimer, Szaldi(a Hungarian who became Amwerican) and some others, but I am not sure, others here are read up on this.

You guys reccomend any books on this topic.  I'm interested in one called "100 suns" anyone ever read it?  I think it has alott of picutes of the bombs as well.

I would highly recommend "The Making of the Atomic Bomb" by Richard Rhodes.   It won the Pulitzer.

I've never read "100 suns" so I can't comment.  

Good luck, it's fascinating reading, and you'll be surprised how many "urban legends" are floating around that really aren't true.

I'm a few chapters into a 2004 book called "THE BOMB: A LIFE" by Gerard DeGroot. So far so good. The physics goes over my head a bit but the rest is fascinating. Germany's efforts, the Russians about to fight the Japanese, the scientists' euphoria and regrets..
I can recommend it on the first few chapters alone.
There is a photo on the back cover of American children hiding under their desks during a practice drill. Does anyone on this forum remember doing this or can you ask ma and pa. I'd love to hear if  they thought at the time that this was useless or they felt that there was a chance of survival under a 2ft x 3ft pice of Beech?

Wow! I've got three stars now. Either I'm Douglas MacArthur or I work at McDonalds.

My neighbour is in his seventies, is profoundly deaf and is watching a porno. It's emabarrasing listening to the dubbed groans of exctasy (SP?). Or maybe he isn't watching a bluey, he has a young girl round, what's your secret buddy?

2nd gripe of the night, Mrs Corbeille opened my 1999 bottle of Chateau neuf du pape to give to friends while we had other bottles of cheaper vin rouge on the rack.  

At least I got out and did a 53 mile bike ride, half of it into a strong westerley wind (anyone in Florida wanna comment on Frances?)
the most I've ridden this year. Ouch! everything hurts,

The child was in a fallout shelter. Many schools were used for fallout shelters, so this was likely a school drill. I remember them well. Yes, we expected to survive. We were told we would survive, if we followed the drill. Remember that this mostly happened during the fifties, during the short time between the development of the atomic bomb, and the hydrogen bomb. Atomic bombs were small, and largely survivable beyond a mile from ground zero. As the arsenals grew from 100 20 kiloton bombs to 10,000 1 megaton bombs, the drill became largely irrelevant. We were all gonna die.

However, in the Soviet Union, the will to survive was much stronger, and civil defense is still practiced. I'm sure it came in handy after Chernoble nuked a few hundred square miles of Ukraine.

I missed out on the nuke drills in school (tornado drills are about the same though) but after some serious study on nuclear effects, I came to the conclusion that the best place to be during a thermonuclear attack would be ground zero. Forget survival, just vaporize me in the first few microseconds and get it overwith.  That way, I literally wouldn't know what happened, because my neurons and synapses would dissipate faster than they could transmit even one impulse.

Yes, I knew an English guy who was fatalistic about it. He used to say that he would paint a Minuteman silo on his house to fool an RV into coming for him. I pointed out that where we were working was one of two places in the western world where the constant-speed drives used in aircraft could be repaired, so the plant was on the target list. He should just stay at work all the time, and he would get his wish.

I think you’re wrong

History

Samuel F. Morse's invention of the telegraph in 1837
-----------------------------------------------
In 1867 a Scottish mathematician, James Clerk Maxwell, conceived of the electromagnetic theory of light.  This theory that light, electric waves and magnetic waves, of varying frequencys, are traveling through the atmosphere.
-----------------------------------------------------------------.
In 1887, a physicist named Heinrich Hertz began experimenting with radio waves in his laboratory in Germany.
--------------------------------------------------------------------------------

Sir Robert Alexander Watson-Watt (1892--1973) was the Scottish physicist who developed the radar.    BRITISH
---------------------------------------------------------------------------------------------
The US Supreme Court said nikola tesla invented the radio before Marconi
A Supreme Court case in 1943 ruled that Tesla was the father of the Radio.
Marconi's first patent was issued in 1900 and Tesla's in 1898.

Typical of the Americans give them an inch and they’ll take 16,070,400,000 miles  
(All measurements are approximate)
 
Ok so your Canadian  (almost the same thing)

Who knows what the above millage actually represents?

The distance light travels in one day.

There are things that survive ground-zero, btw. Freshly sprouted wild bamboo shoots were reported within a week or so after Hiroshima. Gardener's nightmare, that stuff.

Remember a medium warhead will only dent a glacier, for instance (melt a hole less than 100 meters deep, like).

Largest warheads ever made were done by the Russians. They eventually used one to echo the depth of the Urals, which is supposedly the thickest part of the Earths' crust.

Anyone spare a thought for all of the innocent people that died when the bombs were dropped? Its a good job the british soldiers were protected by their uniforms when they tested the first bombs. And how did they know the chain reaction was finate when they clicked the switch? Lucky guess?

Having said that, The invention of the atomic bomb has probably prevented several wars since its demonstration in Japan and possibly saved many more lives than it destroyed. So far so good.

It is not perfect world, but there are several reasons the bomb may have actually saved lives and grief. Asside from the sparing of GI's killed on trying to take Japan mainland there are these thoughts:

1. The backup plan was to starve the Japanese into submission and the Allies were working on destroying crops and transportation between the islands. When the war did end there was some starvation that winter because so much infrastructure had been destoyed, and the allies could not get enough foodstuffs to Japan that winter. Likewise there were food shortages in Germany after the war, not due to a lack of food, but due to the lack of transportation and infrastructure to distribute it.
2. The USSR was gearing up for a Novermber 1945 invasion of Japan. Just think of Japan being a partitioned nation like Germany was. Japan would not have been the nation it is today had the Russins taken half of the country.
3. As far as the innocent victums, I don't know that I accept that. The Japanese were all too happy to enjoy the riches that came from their military conquests and the subjection of China and Korea. They caused a lot of suffering, and I am not aware of any anti-military movements in Japan. The bombs were a necessary wakeup call that changed the course of history for Japan and the world. I respect the Japan of today as a civilized country. I can't say that for the opressive Japan of the 1940's.
I had to do a calculation on the energy of the Hiroshima bomb for science class. It was many years ago, but I believe the answer was 1.2 grams of matter transformed into energy.

Civil defence is not any longer practised in the Soviet Union, because there is no SU any longer.

Chernobyl  did not nuke a few hundred square miles.  There was no major explosion in Chernobyl.  There was a major fire that sent huge amounts of radiation into the environment (some of it even reaching Great Britain), but no explosion.  Chernobyl in in the Ukraine (it was then part of the SU, but since the dissolution of the SU, it is an independent country in its own right).

1. I thought the Allies were actually talking about an invasion, and would not have waited to starve the Japanese out.

Nonetheless, even that would have cost a lot more Japanese lives, let alone Allied lives.

The whole point about the bomb (apart from the fact that it was substantially bluff – what the Japanese did not know was that the Allies only had built the two bombs they used and did not have a stockpile of bombs) was that the bomb should have a massive shock effect.  The point of the shock was that the psychological effect would be disproportionate to the actual casualties caused.

2. The USSR did invade a few Islands that belonged to Japan, and to this day those Islands are a contentious issue between Japan and Russia.

3. No nation is homogeneous.  It is not human nature that 60 million people would agree about anything.  There were many political views within Japan, just as there were in Germany, and America, and Britain, with regard to the war.  In the build up to war, certain political factions became dominant, it does not mean everyone else agreed with that faction, only that they lost those who disagreed lost the ability to influence events (and in some cases, lost the right even to express their views, but that doesn't mean the views were not held in private).

Japan of the 1930's and 1940's was oppressive, but that does not mean that everyone within Japan would have agreed with that policy, it just means that those who could influence Japanese policy at the time were implementing a policy of oppression and aggression, and were painting those who disagreed with them as unpatriotic, and thus making it difficult for open public opposition to their views.
