What we should learn from the history of the US education; and how the future education should be doneJuly 28th, 2016

The US government had to be aware of the significance of science and engineering education especially after World War II. In 1957, the former Russia, Soviet Union, launched the first satellite, Sputnik, as their national project. The nation pride of US was damaged and the national security was also considered at risk then.
This situation forced people to think of improving science education. Thus, the US Department of Education was founded as an independent agency.
With tremendous amount of funding and a number of the projects, the consistent efforts on education resulted in the fact that human landed the moon in 1969 through 1972.
However, in 1980’s, there was a report of overall decline in the quality of science education. In addition, due to the Cold War, it was again considered as nation at risk for US national security.
The numerous projects were launched and they improved the higher education in the US into the world top level. However, the current state becomes much more complicated.
Due to globalization of finance, industries, and work forces, a lot of resources are transferable among countries. In addition, energy and environmental issues give us completely different frameworks to consider a new management of countries and communities.
It may be time to establish a different type of quality education based on science for the next generation which provides another chapter of security for human being and the world. Quality of education will not only enhance nation’s security, but will improve human’s mindset.

How do you explain the nature of light from physics point of view? Why do the Sun and the Moon appear to be the same in size to us when you look at them from the Earth? Is it just an accident?
When you see it in a large scale, light is an electromagnetic wave, it travels through space as a transverse wave. So called white light looks white to naked human eyes because it contains all wavelengths of seven colors of a rainbow. We can only perceive colors in spite of the fact that there are various electromagnetic waves in the world. In fact, we are surrounded by invisible light that technology has made us able to use in everyday life. For example, remote-control, radio wave, mobile phone, etc. In a smaller scale, light acts as gathered particles. There is a machine with attached feathers that was designed to turn when light shines the feather. The machine is called the radiometer. In a much smaller scale, it has been known in physics to determine the energy of light, which is not based on the intensity of light; rather, it is determined by its wavelength.
Also, the way the Sun and the Moon appear to be the same in size to us. Scientifically, we can only say that it is an accident; however, we can not exclude some unknown reason behind it. It is interesting to see that the Earth is the only planet within our solar system that has a satellite as big as the Moon. And if you'd notice, the Moon turns once in its axis while it revolves around the Earth in a month so that showing only the same surface towards the Earth at all time making other side hidden to see from the Earth.
If the distance between the Sun and the Earth had been slightly different, neither of human life nor any form of life on Earth could not have happened.
