Answer 1

In the last two centuries scientific and industrial advancements have taken place making the life comfortable for example agricultural reforms(pesticides and herbicides),nuclear waste ,reasonable housing and better communication etc. the advances in science and medicine have extended life spans from 30 to 60 or even 80 years and improved quality of life as now many diseases and injuries have been healed and epidemics and plague have generally been controlled.

Life would be miserable regarding lack of proper medication,better housing and other technological advancements (internet,telephone etc.) meant for human betterment

Answer 2

Over the past two centuries, many people have used their knowledge, skills, and experience in order to create a host of inventions that have made

Financial Services

Banknote (Paper Currency): Tang Dynasty of China - 7th Century

China is not only credited with having invented paper, but it is also generally recognized to have been the first country in the world to use paper money. The paper money system helped improve economies worldwide as it moved them away from being a barter economy of trade.

Healthcare

Vaccinations: Edward Jenner - 1796

Edward Jenner's work is widely regarded as the foundation of immunology. Jenner is well renowned throughout the world for his innovative contribution to immunization and the ultimate eradication of smallpox.

Local Anesthesia: William Morton - 1846

William Morton was the first to show how ether could be used to allay the pain of operations. His use of anesthesia was displayed at a public demonstration to the surgeons of the Massachusetts General Hospital in Boston on Oct. 16, 1846, where John Collins Warren excised a tumor from a patient's neck. William Morton was neither the inventor nor the discoverer of anesthetics, and for 20 years, acrimony, vituperation, and litigation surrounded the credit for the development of anesthesia.

Antibiotics: Alexander Fleming - 1928

Alexander Fleming discovered the active substance that he termed "penicillin" while working on the influenza virus. Fleming made this discovery by observing that mold had developed accidentally on a staphylococcus culture plate and that the mold had created a bacteria-free circle around itself. He was inspired to further experiment and he found that a mold culture prevented the growth of staphylococci, which verified his discovery. To this day, penicillin is used to treat a host of bacterial infections.

Food and Drink

Pasteurization: Louis Pasteur - 1862

Louis Pasteur developed the process now known as "pasteurization," which is a process of heating food to a specific temperature for a definite length of time and then cooling it immediately in order to reduce the number of viable pathogens that may cause disease. Dairy products, canned foods, juices, syrups, water, and wines are the primary products that are pasteurized today.

Transportation

Modern Automobile: Karl Benz - 1886

Karl Benz patented all of the processes that made the internal combustion engine feasible for use in cars. Karl Benz and his wife, Bertha Ringer Benz, were the founders of the Mercedes Benz automobile manufacturing company.

Energy

Modern Alternating Current Electrical Supply System: Nikola Tesla - 1891

Nikola Tesla filed for seven U.S. patents in the field of polyphase alternating current motors and power transmission. Tesla's patents comprised a complete system of generators, transformers, transmission lines, motors, and lighting. Tesla is also credited with the invention of the radio, although a patent dispute with the Marconi Company that was ultimately decided by the U.S. Supreme Court brings into question if he should receive the sole credit for the radio invention.

Technology

Electronic Digital Computer: John Atanasoff and Clifford Berry - 1937

John Atanasoff and Clifford Berry constructed the first electronic computer with vacuum tubes while working for Iowa State College. The Atanasoff-Berry computer was the first digital computer. It introduced the concepts of binary arithmetic, regenerative memory, and logic circuits. The Atanasoff-Berry machine never reached the production stage and remained a prototype.

Patent Rights

While this list consists of well-known and distinguished inventors, it is important to note that their works were built upon the ideas and labor of many people in order to create the final product or service that we enjoy and use today. Often, many of the contributors to a key invention or innovation may go unremembered and uncompensated, and hopefully, governments throughout the world will strive to resolve this problem by putting in place a more equitable patent system.

The most recent significant step toward accomplishing this goal in patent law was the passage of the America Invents Act on Sept. 16, 2011. The passage of this Act moved the U.S. patent system from a "first to invent" to a "first to file" system, which means that all parties know upfront that if they have a good idea for an invention, they need to be the first to file a patent application with the United States Patent and Trademark Office in order to protect their intellectual property rights. Passage of this Act also eliminated delays previously experienced through interference proceedings and allowed a patented product to come to market in an expedited manner.
