Hiroshima and Nagasaki bombing

A five-ton atomic bomb was dropped over Hiroshima, Japan, by an American B-29. An estimated 70,000 individuals were instantly killed by the bomb’s blast. The exact number of people who ultimately perished as a result of radiation sickness and bomb-related injuries is still up for debate, although it is safe to assume that the total number of fatalities exceeded 100,000 and possibly even 200,000.

Despite the enormous damage that the American military did on Nagasaki and Hiroshima on August 9, 1945, Japan and its wartime foe soon became friendly and productive partners. This connection has persisted to this day. Japan’s citizens consider America to be their country’s finest economic and military friend today.

Rebuilding friendship during the Cold War

The foundations of the strong friendship were laid during the immediate post-war years. The majority of the Japanese people, who were tired from the prolonged years of suffering during the war, applauded the decision to keep the imperial house and reject punitive compensations. However, American leadership actively worked to promote a positive impression of the country and turn Japan into a reliable democratic partner as the Cold War loomed.

Because of its enormous post-war wealth, America was able to lavishly donate money to reconstruct Japan; as a result, the Rockefeller Foundation, American Cultural Centers, and other organizations significantly donated to cultural and educational institutions like major universities and the media. This improved Japanese people’s perceptions of the United States.

In return USA was able to make Japan as a reliable ally to resist Russia during cold war time. So, United States could use its facilities in Japan to assist military operations elsewhere in Asia, import any weapons it desired into Japan, including H-bombs, and even deploy its forces to help the Japanese government quell internal unrest.

That’s how the USA succeeded to rebuild its relationship with Japan.

The reality is pink was not a girly colour until 1953. A particular event was the starting point for this paradigm shift in the fashion world.

‘ Dwight Eisenhower’s presidential inauguration (USA)’ in 1953.

Mamie Eisenhower, the new first lady entered the inaugural ball in a pink attire, which was her favourite colour. Powerful people make history, and the same happened here. All media and fashion designers then started to showcase pink as the colour of women.

That’s the story of the pink colour.

Aeroplane works based on Newton’s 3rd law of motion, but in the case of Gliders, there is no engine at all. Then how does it flies? the answer is an engineering & aerodynamic design.

We all know that even if an aeroplane engine fails, it can fly/glide for a few more distances. That is made possible by taking the advantage of the altitude it already attained. We call it to glide ratio.

The glide ratio of Boeing 747-200 is 15:1 i.e. at 1km height it can glide up to 15kms.

Glider designers took the advantage of this ratio, so they designed gliders with minimum drag & weight so they can attain a glide ratio of 70:1 i.e. gliders can travel up to 70kms from an altitude of 1kms.

But to attain that height gliders need the help of another aeroplane or it needs to be launched from a hilltop.

Gliders are designed in the best aerodynamic way to attain maximum efficiency.

The first thing to keep in our mind is that the magnetic force because of the magnetic field is present around the bar magnet. These field lines are directed from N to S pole direction.

Now refer to the image, Here you can see the magnetic field lines from the N poles of the two magnets are colliding head to head with each other. So these field lines are hitting each other way before the magnets physically touch each other.

Same for the opposite poles, they attract each other before they hit. Hope it helped.
