-The first law, the law of inertia is that if there is not an external force, the object maintains its original state of motion. And it broke Aristotlian view, all moving objects naturally slow down. The second law, the law of acceleration presents the quantitative explanation how the force affects the motion of object. Physics could expect the motion of object by this law. The third law, the law of action-reaction is that there is an equal and opposite reaction in every action. This principle can explain the recoil of a gun and a rocket.

Maria Montessori, an Italian physician and educator, is remembered worldwide for creating a child-centered method of education that transformed the way children learn and grow.
First of all, she introduced classrooms that emphasized discovery and hands-on learning. For example, children used real objects like blocks and beads to learn by touching and exploring. This approach allowed students to develop problem-solving skills and a deeper understanding of the world around them.
Next, she encouraged children’s independence, individuality, and creativity. In her schools, students could choose their own activities and work at their own pace, which helped them build confidence and responsibility for their own learning. Montessori believed that when children are free to follow their interests, they become more motivated and engaged in their studies.
Finally, her Montessori method spread globally and continues to shape modern education. Today, Montessori schools can be found in many countries, and teachers still follow her ideas to guide students through self-directed and experiential learning.

Therefore, Maria Montessori’s innovative ideas not only transformed education in her time but also continue to inspire the way children learn and teachers teach around the world today.

First of all, he created Hangul for people who could not express their own opinions. In the early days, most of the writings were written in Chinese characters, so commoners had difficulty learning knowledge. They had no choice but to endure injustice even if it was unfair. King Sejong didn’t turn a blind eye to these people’s suffering, but created Hangul reflecting the shape of phonetic system and philosophical principles of heaven, earth, and people. This innovation in language led people to read and understand the government’s laws and moral texts, such as Samgang Haensil Do. Furthermore, as they became able to personally write petitions appealing injustice, their voices eventually began to be heard by society.

 Second, Sejong invented Cheugugi to measure rainfall and the Clepsydra, a water clock. Using a standardized iron container, people could quantitatively measure the rainfall. Accurate measurement of rainfall contributed to predicting river water level and risks of flood. Earlier water clocks required manual drumming which caused errors due to people’s mistakes. Meanwhile, Clepsydra automatically rang a bell at a set time powered by flow of water. This helped people to systematically plan their lives and ensured efficient management.

To sum up, Sejong’s reforms in language and science left a lasting positive impact on the common people’s lives. Hangul, Cheugugi, and Clepsydra were not just scientific achievements, but the love spirit for people.

First of all, Facebook influenced the social networking era by changing the way people communicate. In the early 2000s, we used to contact friends and family by phone, email or letter. However, the emergence of Facebook changed all that, making communication much simpler. People started to communicate with others and express their emotions more easily online. For example, Facebook's 'Like' feature, the first of its kind, simplified the way people express emotions. Many other social networking services then adopted similar features, such as hearts and reaction buttons, to allow users to express their emotions more easily.

Moreover, Facebook has also had an amazing impact on the business and advertising industries by innovatively connecting with users. Facebook made precise targeting possible by using user data such as gender, age, interests, behaviour and location. This enables advertisers to display their ads to specific groups and increase their advertising efficiency. Consequently, several companies use Meta's services, such as Facebook, to advertise themselves. According to a report, the Chinese shopping app Temu spent around 2 billion dollars on ads for Facebook and other Meta services in a single year, which is a considerable proportion of Meta's profit.

In conclusion, these examples demonstrate how Mark Zuckerberg’s ideas have given rise to new lifestyles and eras.

To sum up, Edison’s inventions and research labs revolutionized modern life and laid the foundation for today’s technological progress.

First of all, he ended the unfair system that separated Black and White people, known as apartheid. Mandela fought for freedom and equality because he believed that all people deserved the same rights and opportunities. As a result of his fight against injustice, he was sent to prison for twenty-seven years. However, even though he suffered for many years, he never gave up his dream of a free and equal nation. After his release, Mandela continued to work for peace and became South Africa’s first Black president in 1994. During his presidency, he promoted forgiveness, unity, and democracy, encouraging people of all races to live together in harmony. His courage, patience, and kindness inspired not only South Africans but also people all over the world.

In conclusion, Nelson Mandela will always be remembered as a true hero who turned pain into power and led his country from division to freedom.

Although Jobs was known for being strict and sometimes difficult to work with, his passion and vision made Apple one of the most successful companies in the world. He proved that even with personal struggles, a person can change the world through innovation and determination.

During the 18th century, chemistry was filled with confusion and speculation, dominated by the outdated phlogiston theory, which claimed that all materials released a mysterious substance during burning. Lavoisier boldly challenged this idea through careful measurement and experimentation. He demonstrated that combustion and respiration both require oxygen, fundamentally transforming our understanding of chemical reactions and life processes. His insistence on quantitative methods—measuring substances before and after reactions—led him to establish the Law of Conservation of Mass, which states that matter is neither created nor destroyed in a chemical reaction.

Beyond his laboratory achievements, Lavoisier also played a key role in organizing and clarifying chemical language. He helped develop a systematic nomenclature for naming elements and compounds, making scientific communication clearer and more universal. His book, Traité Élémentaire de Chimie (Elements of Chemistry), became a landmark text that laid the foundation for modern chemistry.

Despite his immense contributions, Lavoisier’s life met a tragic end. As a government official responsible for collecting taxes, he became a target during the French Revolution and was executed in 1794. However, his legacy endured—his methods, principles, and discoveries continue to influence scientists centuries later. Antoine Lavoisier did not just experiment with substances; he transformed chemistry into a true science built on evidence, precision, and reason.

In conclusion, Max Planck’s development of quantum theory not only transformed traditional physics but also paved the way for future scientific and technological progress. His lifelong dedication to research continues to inspire scientists around the world today.

First of all, he revolutionized personal computing by making computers accessible and user-friendly such as Apple I and Apple II. In 1976, he created Apple 1, which was a basic circuit board sold to hobbyists and then, in 1977, he introduced Apple 2, which was a major breakthrough about personal computer with features like color graphics and design.
