2、s/disadvantages of science and technology?In your opinion, what is the greatest technological invention? Why?How will science change the world in the next 100 years?,Science & Technology,Science refers to knowledge about the structure and behavior of the natural and physical world, based on facts th
3、at you can prove, for example by experiments. Technology refers to scientific knowledge used in practical ways in industry, for example in designing new machines.,10 inventions that changed the world,1.ElectricityIt is true that Benjamin Franklin holds the title as the father of electricity, but his
4、 invention and discovery was life threatening because he has demonstrated it through the natural lighting using lightening rod that could had caused his life in order to see the electric flow. Hence, there are others who triggered, and did study who had prepared documents and books in order to catch
5、 the whole process and technicalities of electric power. Everything in the modern world depends on electricity.,2. Light Bulb,Who would ever forget the creation of Thomas Alva Edison of an electric light called bulb in 1879 which has caused one of the biggest changes in the world not just to househo
6、lds, but in running all businesses in the world. It was patented on January 27, 1880, wherein it categorically classified as the first practical light.,3. Refrigeration,William Cullen was the first person who initiated and introduced artificial refrigeration in 1748 which he has demonstrated at the
7、University of Glasglow. Oliver Evans improved it when he invented the first refrigeration machine in 1805, and in 1834, the first practical refrigerator was made by Jacob Perkins, then an improvement was done by John Gorrie which he has based from Oliver Evans fridge.,4. The Wheel,Prior to the devel
8、opment of automobile, wheels had served greatly to the progress of vehicles that we are enjoying these days. It started in a primitive axle that served as rollers until the evolution of the functional wheels. In fact, it can be traced back around 3500 B.C. from the Ancient Mesopotamia where oldest w
9、heel can be seen. Hence, the first sets of wheels were used for potters to transport pots, and food which was called as potters wheels. An improvement was done during Sumerians era where they called it as wheeled chariots. Later on gears were added at Middle Age, until Industrial Revolution came whe
10、re steam engines, railroads, and factories were found.,5. Automobile,Based on the history, Karl Benz was the first modern inventor of automobile in 1886. Nonetheless, in 1672, the first steam-powered vehicle was designed and introduced by Ferdinand Verbiest while in 1769, the self-propelled mechanic
11、al vehicle was invented by Nicolas Joseph Cugnot, then in 1807 the first internal combustion engine(内燃机) was made by Nicephore Niepce. In 1881, a 3-wheeled vehicle came into the picture through Gustave Trouve and lastly, Karl Benz from Germany developed his very own four-stroke cycle gasoline engine
12、. In 1893, the first gas-powered car was invented by Charles Edgar Duyea along with his brother, Frank.,6. Printing Press,Johannes Guttenberg was the known creator or inventor of printing press. He was a known businessman and goldsmith in Germany. Everything began when he borrowed specific sum of mo

Although, various improvements were made, but definitely, his creation has triggered to wha
14、t the technology has to offer in the society today.,7. Radio,There were people who had made studies, and research with regards to radio transmission. They are James Clerk Maxwell, Heinrich Hertz, Guglielmo Marconi and this became possible through wireless telegraphy. Nonetheless, majority of the dev
15、elopments and discoveries were done by Guglielmo Marconi who had concocted the wireless transmission, and Mr. J. Vincent Waine who designed the transmitting & receiving equipment.,8. Flight and Aviation,It began with kites and gliders to check for calculation of the length of the tunnel, then later
16、on, the discovery of hydrogen that pave the way to the creation of balloons. There were series of attempts prior to serious study of Leonardo da Vinci in 1485 about flight wherein he represented it through drawings. Later on hot air balloons were created by Joseph Michael and Jackson Montgolfier. By
17、 1799 to 1850s, gliders were invented by the father of aerodynamics, George Cayley. The Wright Brothers: Wilbur and Orville Wright. They called their first plane the flying machine.,9. Telephone & Telegraph,Because of the ingenious mind of a 29-year old man in 1876, the first telephone was invented
18、by none other than, Alexander Graham Bell and with the assistance of Elisha Gray who had made the design of transmission of communication done through an electronic device.,10. Computer,In fact, it started with a simple abacus which served as an aid for computation. Indeed, from the world itself, co
19、mputer comes from the root word compute.By 1822, Charles Babbage steam driven calculating machine which was also known as Difference engine where two important components called as store and mill composed of an Analytical engine which are known today as CPU and memory unit. Harvard Mark I in 1944, t
