Examples of Technology Developed After Understanding Natural Laws


1. Airplanes

The development of airplanes is a prime example of how technology can be developed after understanding natural laws. The Wright brothers, who are credited with inventing the first successful airplane, studied bird flight extensively before designing their aircraft. They observed that birds had the ability to change the angle of their wings to control their flight and maintain balance. The brothers used this knowledge to design the wing shape and control mechanism of their airplane, which allowed it to fly through the air with stability and control. Today, airplanes continue to be designed and improved upon using the principles of aerodynamics and fluid mechanics, which are natural laws that govern the behavior of air and other fluids.


2. Solar Panels

Solar panels are another example of technology that was developed after understanding natural laws. Solar panels work by converting sunlight into electricity through a process called the photovoltaic effect. This effect was first observed by French physicist Edmond Becquerel in 1839, who noticed that certain materials produced a small electric current when exposed to light. This phenomenon was later explained by the laws of quantum mechanics, which govern the behavior of particles at the atomic and subatomic level. Today, solar panels are used to generate clean and renewable energy, and their efficiency and cost-effectiveness continue to improve as we gain a better understanding of the natural laws that govern their operation.


3. MRI Machines

MRI (magnetic resonance imaging) machines are a medical technology that uses natural laws to create detailed images of the human body. MRI machines work by using a strong magnetic field and radio waves to detect the behavior of hydrogen atoms in the body's tissues. This technique was first discovered by physicist Felix Bloch and Edward Purcell in the 1940s, who observed that the behavior of hydrogen atoms changed in the presence of a magnetic field. Today, MRI machines are used to diagnose a wide range of medical conditions, from cancer to neurological disorders. The technology continues to be refined and improved upon as we gain a better understanding of the natural laws that govern the behavior of atoms and molecules in the human body.

Similar Class 12 Doubts

Read the following text and answer the following questions on the basis of the same: Capacitor Colour Code: Capacitor values as written on small capacitors are sometimes misleading. Letters like p (pico) or n (nano) are used in place of the decimal point to identify its position and the value of the capacitor. For example, a capacitor labelled as n33 = 0.33nF, 8n2 = 8.2nF, 22n = 47nF and so on. Sometimes capacitors are marked with the capital letter K to signify a value of Kilo pico-Farads. As for example, a capacitor with the markings of 100K would be 1000 × 100 pF = 100 Kpf = 100 nF. Sometimes, a three letter code consists of the two value digits and a multiplier. For example, the digits 471 = 47 × 10 = 470 pF, 332 = 33 × 100 = 3300 pf. To reduce these confusions an International colour coding scheme was developed almost the same as that of resistance colour code.The value obtained from colour code is in pf.68k is written on a capacitor. What is its value?

There is a controversy raging over the entry of giants such as Tesco and Wal-Mart into India after the government last week permitted foreign direct investment (FDI) in multi-brand retail. Most economic analysts look at it in terms of capital coming into India to oust local shopkeepers or in terms of capital coming in to offer better prices to farmers or set up distribution chains and storage facilities to help consumers. These arguments seem a little old. There is a technological dimension to this that may reveal that it is India that is behind the competitive edge of big retail chains.In 2009, Wal-Mart picked Bangalore-based Infosys Technologies and India-centric Cognizant among three information technology service vendors for a $600 million multi-year contract. Finance is now easily available for retail companies from banks and equity markets. What sets the real smart retail giants apart is their ability to leverage software and IT to keep their competitive edge.Supply chain software can help lower costs by managing inventories. Data analytics and customer relations software can help them identify the more lucrative customers or choose discount strategies. Partners, employees and vendors of retail giants are now connected by software. Indian talent figures in all this.Infosys was an early adapter of Wal-Mart’s move to go in for radio-frequency identification (RFID) tags that helps the retail chain track inventories at low cost. Last year, Wal-Mart also acquired Kosmix, a cutting-edge search engine, founded by Indian-born Venky Harinarayan and Anand Rajaraman (who earlier co-founded Junglee.com that Amazon acquire d). Now Kosmix is a part of WalMart Labs. Its technology filters and aggregates information by topic from Twitter messages and the larger Web in real time. This is a new way to interact with shoppers.Tesco now owes its edge to its Bangalore IT facility called the “Hindustan Service Centre”. The British retail chain says 6,000-employee-strong HSC’s strategic initiatives cover the “IT, business, financial, commercial and property aspects.” In Bangalore, Indian techies develop tools like mobile applications for Tesco.Q. Which of the following options best explains the purpose of the last four paragraphs?
