Deskripsi video : Do you know who invented the phone? How did the phone change the way we communicate? What other technological innovations were inspired by the great work of Alexander Graham Bell? If you want to know the answer, watch this video! This video will explain the life and achievements of Alexander Graham Bell, a scientist and teacher for the deaf who invented the phone in 1876. You will see how Bell was interested in sound technology because his wife and mother were deaf. You will also learn about other inventions and research that Bell did, such as phonograph, metal detector, and heavier-than-air flight. This video will give you insight into the development of phones from time to time, from wired phones that use analog system, to wireless phones that use digital system, to smart phones that can send messages, photos, videos, and other data. You will also see how phones affect business, family, and government. #phone #invention #alexandergrahambell #soundtechnology #phonograph #metaldetector #heavierthanairflight #phonehistory #phoneevolution #smartphone #business #family #government #History #aihistory #teknologiai

In this video, we will see how Antony van Leeuwenhoek, a Dutch scientist known as the father of microbiology, made his tiny lens and discovered a whole new world of microbes invisible to the naked eye. #Leeuwenhoek #Microscope #Microbiology Leeuwenhoek made a simple microscope consisting of a single high-quality lens with a very short focal distance. He was the first person to observe bacteria, protozoa, and sperm cells using his microscope. His research refuted the doctrine of spontaneous generation and laid the foundations of bacteriology and protozoology. Leeuwenhoek made his lenses by sharpening glass until it was thin and perforating it with a needle. Other lenses he made by melting glass and using small, very hot droplets that he shaped into almost spherical balls as they cooled. This method was described in 1678 by the influential English microscopist Robert Hooke, who inspired other scientists to do the same. Leeuwenhoek observed a wide variety of small objects with his microscope, such as the structure of eye lenses, muscles, insect mouthparts, and the fine structure of plants. He also discovered parthenogenesis in aphids. However, his greatest discovery was the microbes he isolated from various sources, such as rainwater, pond and well water, and human mouths and intestines. He also measured their size. Leeuwenhoek reported his discoveries to the Royal Society of London, a prestigious scientific organization that published the journal Philosophical Transactions. Although Leeuwenhoek had no academic background and did not speak Latin, the scientific language of the time, the Royal Society recognized his contributions and made him a member in 1680. Leeuwenhoek died in 1723, at the age of 90. He left behind more than 500 lenses and about 200 microscopes, most of which were made of silver or brass. He also left detailed notes about his research, which became a valuable resource for scientists of the time. Leeuwenhoek is considered one of the pioneers of microscopy and microbiology, and his legacy lives on today.

Do you know who invented the battery for the first time? A battery is a device that consists of one or more electrochemical cells that have external connections to provide electric power. Batteries can be used to power various electrical devices, such as remote controls, clocks, cell phones, and cars. However, batteries did not just appear out of nowhere. There is a long history behind the invention of batteries. In this video, we will discuss Alessandro Volta, an Italian scientist and inventor who created a battery with a simple method called the Volta stack. He was inspired by Luigi Galvani's research, who discovered that a cut frog leg could twitch when touched by different metals. Volta proved that the movement of the frog leg was caused by the electric current generated by the contact between two different metals, not by the animal electricity claimed by Galvani. Volta also found that the electric current could be increased by stacking metal discs separated by paper or cloth moistened with an acid or salt solution. He connected the ends of the metal stack with wires and produced a high enough electric voltage. Electric voltage is the potential difference between two points in an electric circuit. The unit of electric voltage is named volt to honor Volta's service. The invention of the battery by Volta was a great breakthrough in the field of science and technology. The Volta battery enabled scientists to conduct experiments with stable and measurable electric current. The Volta battery also became the basis for the development of subsequent batteries, such as the Daniell battery, the Leclanche battery, and the dry battery.

Who was Alfred Nobel? What made him famous? How did he create the prestigious Nobel prize? This video will answer these questions by revealing the life story, inventions, and motivations behind this remarkable figure. Alfred Nobel was a Swedish chemist, engineer and entrepreneur who invented dynamite and other more powerful explosives. He also founded the Nobel Prize, which is awarded annually to individuals or organizations meritorious in the fields of peace, literature, physics, chemistry, physiology or medicine, and economics. Alfred Nobel was born in Stockholm, Sweden, in 1833, to a family descended from Olof Rudbeck, a Swedish technical genius of the 17th century. He was fluent in English, French, German and Russian, in addition to Swedish. He also wrote poetry and plays, and was interested in social issues and peace. Alfred Nobel spent most of his youth in St. Petersburg, Russia, where his father owned a military equipment factory. He studied chemistry and technology in Paris and the United States, and worked under John Ericsson, a Monitor warship builder. After returning to St. Petersburg, he worked at his father's factory, which went bankrupt after the Crimean War ended. Alfred Nobel then moved to Sweden and began experimenting with nitroglycerin, a highly dangerous explosive. He managed to stabilize nitroglycerin by mixing it with clay, and created dynamite in 1867. He also invented detonators, gelignite and ballistite, all of which increased the power and safety of explosives. Alfred Nobel set up companies in various countries to produce and sell his explosives, which were used for both civilian and military purposes. He became very rich and famous, but was also criticized for contributing to the destruction and death of war. He felt guilty and wanted to leave a better legacy for the world. In 1895, he wrote his will, which set aside most of his wealth to establish the Nobel prize. He died in 1896 in San Remo, Italy, and the first Nobel prize was awarded in 1901. This video will give you a more in-depth look at Alfred Nobel's life, discoveries and motivations, as well as his impact on the world. You will also see some of the most famous Nobel prize recipients and their achievements.
