 Japanese people are known for their intelligence, strong health, politeness, and wellness. But why is this nation so unique and different from the rest of the world? We at Bright Side seem to have found the answer: they have an incredibly cool education system! Manners before knowledge . In Japanese schools, the students don’t take any exams until they reach grade four (the age of 10). They just take small tests. It is believed that the goal for the first 3 years of school is not to judge the child’s knowledge or learning, but to establish good manners and to develop their character. Children are taught to respect other people and to be gentle to animals and nature. They also learn how to be generous, compassionate, and empathetic. Besides this, the kids are taught qualities like grit, self-control, and justice. The students clean their school themselves. In Japanese schools, students have to clean the classrooms, cafeterias, and even toilets all by themselves. When cleaning, stud...

 The heart is one of the most important organs of human body. It is a muscular organ responsible for pumping blood through the blood vessels by repeated, rhythmic contractions. The term cardiac (as in cardiology) means "related to the heart" and comes from the Greek word kardia , for "heart". The heart pumps the blood, which carries all the vital materials that help in various body functions. For example, the brain requires oxygen and glucose, which, if not received continously, will cause it to loose consciousness. Muscles need oxygen, glucose and amino acids, as well as the proper ratio of sodium, calcium and potassium salts in order to contract normally. The glands need sufficient supply of raw materials from which they manufacture the specific secretions. If the heart ever ceases to pump blood, the body begins to shut down and after a very short period of time, death occurs. All vertebrates including humans have a single heart. Location of heart-: In the human b...

  In most organs and tissues of a mature animal, a balance is maintained between cell renewal and cell death. The various types of mature cells in the body have a given life span; as these cells die, new cells are generated by the proliferation and differentiation of various types of stem cells. Under normal circumstances, the production of new cells is regulated so that the number of any particular type of cell remains constant. Occasionally, cells arise that no longer respond to normal growth control mechanism. These cells give rise to clones of cells that can expand to a considerable size, producing tumour which ultimately leads to cancer. Cancer is a dreadful disease and is one of the chief killers today. It commonly originates in the tissues in which the cells are regularly replaced by mitosis. Cancer or malignant neoplasm is a disease of uncontrolled proliferation of cells without any differentiation. The cancer cells invade and destroy the surrounding tissues. Normal cells s...

 T he speed of light is one of the most fundamental constants in physics. Here are some interesting facts about the speed of light: The speed of light is approximately 299,792,458 meters per second, or about 186,282 miles per second. This means that light can travel around the Earth’s equator about 7.5 times in one second. The speed of light is the maximum speed at which energy, matter, and information can travel in the universe. Nothing can travel faster than the speed of light. The speed of light is constant in a vacuum, meaning that it does not change regardless of the observer’s motion or the direction of the light beam. This principle is known as the theory of relativity. The speed of light was first measured accurately by Danish astronomer Ole Rømer in the 17th century using observations of the moons of Jupiter. The speed of light is used as a fundamental constant in many scientific calculations, such as the calculation of distances in space and the determination of the masse...

  The first human space adventure was an extraordinary event that marked a significant milestone in human history. It was a feat of human ingenuity and determination that pushed the limits of what was considered possible. In this blog, we will explore the history and significance of the first human space adventure. The Space Race The Space Race began in the late 1950s, during the height of the Cold War, between the Soviet Union and the United States. The Soviet Union was the first to launch a satellite, Sputnik 1, into orbit on October 4, 1957, which sent shockwaves through the United States. The Soviet Union continued to make advances in space exploration, launching the first animal, the first man-made object, and the first woman into space. The First Human Space Adventure On April 12, 1961, Soviet cosmonaut Yuri Gagarin became the first human to journey into space. Gagarin's Vostok 1 spacecraft was launched from the Baikonur Cosmodrome in Kazakhstan, and it orbited Earth once bef...
