The nuclear age and the cold war

Module 13

The nucleur and space race

Activity 1:

To historically research the cold war by the use of cause and effect, continuity and change, comparisons and conclusions: the nuclear and space race

[lo 1.1, 1.2, 1.3, 2.4, 3.2, 3.3]

SOURCE A:

Interview with Harold Agnew, circa 1949, American nuclear physicist

After the destruction of the Second World War, nobody expected the Soviet Union to have the infrastructure to produce a nuclear bomb. They certainly did.They had to possess information on the Manhattan Project.

SOURCE B:

Commentary of Robert Oppenheimer, American Nuclear expert

If another world war breaks out, mankind will be destroyed. We should ask ourselves whether mankind is doing enough to prevent it.

SOURCE C:

Interview with the Soviet military strategist, Valentin Laryonov, 1950

Malkenkov warned the whole nation and world population that an atomic war would destroy the entire world and that such a war should be avoided at all costs.

SOURCE D:

Comment of Galina Mishina, baker in Moscow, circa 1989

In the fifties we did not realise that the Americans were afraid of a Russian attack. We were under the impression that they knew that we pursued peace and that we wanted to live in peace. We wanted to develop our country, it is written nowhere that we wanted to invade any country.

SOURCE E:

Comment of Jean Asam, American student during the fifties

We wanted to protect ourselves against bombs and run no risks. Therefore we built bunkers and shelters in our backyards. It happened quite commonly in American suburbs.

SOURCE F:

An eyewitness account by Harold Agnew, American Nuclear physicist on the experimental nuclear explosion in the Pacific Ocean in 1954

We were not prepared for such a powerful explosion and large fall-out area. A Japanese fishing vessel, “ The Happy Dragon” was contaminated through the nuclear fall out. The vessel was quite a distance from the test site. Before we realised what had happened, the fishermen were radio-actively contaminated. The fishermen were 120 km away from the explosion. One out of 24 crewmen survived. A mistake was made. The wind carried the radio-active fall-out farther than expected. It is regrettable that people were contaminated…

SOURCE G:

Comment by Oleg Troyanovski, Kruschev’s adviser on satellites

In Kruschev’s opinion, warships and bombers have become obsolete and that in future missiles will take their place. For that reason technicians from all over the Soviet Union got together in the desert at Baikonur in Kazakstan to work on satellite development. On 4 October 1957 we launched the first space satellite, Sputnik (means travelling companion of the Earth). The Americans always pretended that they were the richest and technologically the most advanced country in the world. With Sputnik that travels around the earth, this perception changed.

The Spacecraft

Russian Soyuz TM-34 capsule.

Length: 7,5 metres.

Weight: Just over 7 tonnes.

Reaches space in approximately 8 minutes powered by a Soyuz rocket.

can someone help me with some logarithmic and exponential equations.
Jeffrey Reply
sure. what is your question?
ninjadapaul
20/(×-6^2)
Salomon
okay, so you have 6 raised to the power of 2. what is that part of your answer
ninjadapaul
I don't understand what the A with approx sign and the boxed x mean
ninjadapaul
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
Salomon
I'm not sure why it wrote it the other way
Salomon
I got X =-6
Salomon
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
ninjadapaul
oops. ignore that.
ninjadapaul
so you not have an equal sign anywhere in the original equation?
ninjadapaul
hmm
Abhi
is it a question of log
Abhi

or infinite solutions?
Kim
The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

what is the application of nanotechnology?
Stotaw
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
Azam
anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
Prasenjit
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
Damian
silver nanoparticles could handle the job?
Damian
not now but maybe in future only AgNP maybe any other nanomaterials

this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
Prasenjit
can nanotechnology change the direction of the face of the world
Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.
Ali Reply
the Beer law works very well for dilute solutions but fails for very high concentrations. why?
