《Dispute which the last independent country in Africa has.》


Eritrea is a country which Italy succeeded in colonizing in 1890 for the first time.Italy planed to occupy the whole Ethiopia,but failed in it,so occupied an area of the present Eritrea.After that,Italy made Eritrea be independent,according to peaceful agreement.😃


However,in the beginning of the 20th century when uproar of Fascism swept over the whole Europe,Italy burnt its ambition again,attacked and occupied Ethiopia.Both Ethiopia and Eritrea became Italian colonies.☀

However,Italy suffered a crushing defeat in the World WarⅡ.Instead England started to occupy Eritrea then.When withdrawing from Eritrea,England formed a federation with Eritrea in 1952,according to the UN's decision.😃


After that,Ethiopian parliament resolved Eritrea's annexation 併合 to it one-sidely in 1962,and occupied Eritrea.In this way,Eritrea's dispute for liberation started.🆚

Eritrea is one of the poorest country in the world.Its unemployment rate reaches no less than 90%！Most of the people can't get jobs…😥


The people who have never been educated since they were born account for 80% in the country.The whole family have to work for its living expenses 生活費,it's natural for even elementary school children to work.It's said that even three meals a day is hard.😣


Why did they want to be independent?They chose pride as the people of Eritrea rather than the hardship,starvation and so on which they are forced to confront.How hard situations they are in,I'm wondering.😣


It doesn't always mean that I have compassion on them.It's just that I've given my impression on it.😒

The problem is the amount of criticality. If we make pure uranium 235 a lump which exceeds the amount of criticality,even if we leave it alone,it'll become an atomic bomb and blow up automatically.🔥


The problem is the next one. When we try to explode it,how do we make it reach the amount of criticality? Its elementary answer is in an early atomic bomb.Two atomic bombs dropped in Japan in 1945.The one was in Hiroshima,the other in Nagasaki.☝


《Forms of the atomic bomb》


The two atomic bombs were different in regard to the forms and explosives 爆薬 altogether. In a word,we call the type of Hiroshima the one of gun barrel 砲身. Uranium was used for it.

《Fast neutron and slow one.》


A neutron which has just generated from an atomic fission has plenty of energy.It's kinetic energy 運動エネルギー.😃


The neutrons' mass are all the same,whether amount of energy is big or small appears as its speed.In a word,the neutron which has just given off is at the speed of no less than 20 thousand kilometers per second.It's one tenth of the speed of the light.It's so speedy that we call it a fast neutron.☝


On the other hand,as time passes,the neutron collide with other things often,so the neutron loses its energy.It slows down to 2.2 Kilometers per second,but it's still about 30 times as fast as a Shinkansen.We call the neutron 熱中性子.😚
