Hi there, I have a question about the Teller–Ulam hydrogen bomb design. This will be a long post , but I hope someone can answer it for me. When the first bombs were created, uranium device was simple enough to to figure out. Two sub critical masses of u-235 joined at... I...

Hiroshima "Little Boy" Atomic Bomb Physics Help I just wanted some feedback on a paper I just finished. Did I do everything correctly and does it make sense? It seems my data supports information I found online: "It contained 64 kg (140 lb) of uranium, of which less than a kilogram underwent...

Hi, I am tasked with constructing a scale model of Fat Man that can be broken down. Would anyone happen to know of any particular components, visible structures of the device, and any other necessary details. It is a long term project yet I can find no clear picture.

I know that a teller-ulam device uses lithium deuteride as its nuclear fuel. I know very little about chemistry, but why is a hydrogen bomb called a hydrogen bomb, if its nuclear fuel is lithium deuteride? Is it the hydrogen atom in the lithium deuteride that creates the fusion process?

From 1945 until the US put a ban on aboveground nuclear explosions in the US, there were some 300 nuclear devices exploded aboveground in the US. These explosions lead to an eventual nuclear fallout. Anyone have resources like books or internet sites that detail the medical research and overall...

Homework Statement The energy released by nuclear bombs is measured in kiloton (kt) or megaton (Mt) units. One kiloton is a unit of energy released by 1000 tons of trinitrotoluene (TNT). One kiloton is 4.2×1012 joules. The yield of fission bombs is typically between 10 and 500 kilotons, the...

What is different between a bomb calorimeter and a coffee cup calorimeter that makes one only constant volume and the other only constant pressure? to me, it seems that both of them should have constant volume because they are both closed containers... and why is the pressure in a coffee...

Terror has struck the Norwegian capital today. At 15.26 local time (roughly two hours ago), what appears to have been a car bomb blasted off in the governmental quarters in Oslo. Several have been confirmed dead; although none of our political leasers/ministers seem to be missing/hurt. This a...

Are the following assumptions about this thought experiment correct?... If an interference pattern is detected the bomb is defective because there was never any possibility of a photon being observed and collapsing the wave function. In the case that no interference pattern is detected and...

Could someone please clarify if my understanding of the following is correct or not? When a bullet is fired from a gun or a bomb explodes, I thought I had read somewhere that, in the first few microseconds, the speed of the bullet or bomb blast is slow at first then increases to a maximum...

i need to calculate the volume of total destruction of a nuclear bomb its like here http://en.wikipedia.org/wiki/File:Tsar_Bomba_Paris.png what formula i need to use to calculate area of total destruction zar bomb already has some infos : 50MT tnt = 35km total destruction (detonation...

Hello, Chitose here. First, I don't know which group should I post this but I put it here just in case. ........ As topic says, Can bomb still explode in vacuum area such as space? I heard that fire cannot lit without oxygen. but a lot of sci-fi movie show explosion scene in space...

hey guys just a simple question, I think. How fast does the nuclear fusion/fission reactions n explosion occur? Is it at the speed of light? Will there be any energy release b4 the explosion, Or should only b after the explosion? I always thought the fission/fusion reaction cause it to...

Why can't every country make an 'Atom Bomb' ? Everyone knows that we require a fissionable material and an explosive. What else is required that is to be invented (rather discovered) by other countries? All comments are welcome.

Homework Statement I'm writing a paper on the Manhattan Project, and as part of this paper I am asked to show: "... calculations that can help illustrate the explosive power of an atomic bomb compared to ordinary explosives."Homework Equations Released energy per fission: Q = \Deltam * c2 The...

"Told science" Hi guys! I am going to take part in a literature project, which is called "told science". You have to write a scientific eassy such as a story. For this year I was wondering to write down something about the atomic bomb. My idea was to write the best quotation on atomic bomb in...

I have seen many people both on TV and newspaper articles say that religion has much to do in pushing, motivating someone toward the idea of suicide bombing. I won't go into details to support my thesis but I believe a human doesn't really follow, adhere to any particular religion. They choose...

This was probably asked some time ago. It involves a paradox of relativity and I hope someone can answer it for me: Imagine a solid cylinder (call this the plunger) with a bar welded to one end making a T. The plunger fits just perfectly into a hollowed cylinder of the same length, and the...

What I always thought is that the strong force in each atom, when the nucleus is impacted and is separated, some of the nuclear force is let out. Multiply this by billions, and voila.

I am going to define these things as I understand them. Please correct/refine them as necessary. A bomb calorimeter is a small volume capsule within a tank of water. A reaction is carried out within this small capsule and the heat evolved is transferred to the water and the heat change of the...

Here, tell me if this will work. A chamber made of thick lead is taken and a vacuum is put on it. There are electromagnets between the lead. A ball of unstable uranium and osmium that is plated with iron is put in the chamber and suspended by the magnets. Then protons and neutrons are...

It appears that common ragweed is the major cause of pollen allergy, for instance this study. The Netherlands has taken initiative to eradicate the American intruder in the local plant community. For instance (Dutch) Google translation of the first paragraph: So everybody is urged to...

I design weapons for fun and have just heard of an ion bomb. First off is It even possible to use ions to make a destructive device?

Sorry for silly question but I can't find the answer anywhere. Is any kind of moderator used in nuclear bomb (or the mass of the uranium is so big that neutrons speed need not to be reduced). Thanks.

In bomb calorimeter, when dry ice is added to warm water, the final mass of the inner cup and remaining water is less than the initial mass of the inner cup and water. The calorimeter did not decrease in mass so it means water is lost but not gone it just changes it state. The water was in...

Homework Statement The fireball of a uranium fission bomb consists of a sphere of radius = 15m and temperature 300,000K shortly after detonation. Assuming that the expansion is adiabatic and that the fireball remains spherical, estimate the radius of the ball when the temperature is 3000K...

http://www.cnn.com/2010/CRIME/05/02/times.square.closure/index.html?hpt=T1 Fortunately it started to smoke early, so it was noticed in time to tip off the police, who cleared the area and defused it. No indication yet of who planted it.

had this idea a while back, but its basically like a large penning trap. its just a basic concept so bare with me. you construct a penning trap, but in a spherical shape instead of the classic penning design, which is similar to a magnetron. having each containing magnet positioned in series on...

hi, not that I'm going to make one, I'm asking just out of curiosity Would it be possible to make an antimatter bomb by using regular h-bomb and radioisotopes like those used in pet scanners?

The Electoral College (and the Supreme Court) gave the 2000 US presidential election to GW Bush over Al Gore despite that fact that Mr Gore won the popular vote. It wasn't the first time this happened. In 1876 the Electoral College, based on an electoral margin of one vote (181 to 180), gave the...
