Amazing science quiz -Part 1

What is nanotechnology?

Nanotechnology, a new science field, aims at understanding matter at scales of 1 to 100 nanometers. Nano materials can be created or found in nature. Nano particles and nano tubes are just a few examples of different nanomaterials. All dimensions of nano particles are nanosized. Nanotubes, which are long cylindrical strings made up of molecules with a nanosized diameter, are these things. Nanofilms are thin, but may have other dimensions.

Researchers are working to find ways to use nanotechnology in a variety of areas, such as transportation and electronics, medicine, and sports. Nanotechnology fabrics have added insulation and no bulk.

Some fabrics have coatings that make them stain-proof. To treat and diagnose health issues, nanorobots can be used in medicine. Nanotechnology is being used in electronics to shrink the size of many electronic devices. Food industry researchers are exploring the possibility of using nanotechnology to improve the taste of food. They are also looking for ways to incorporate antibacteri1]ial nanostructures in food packaging. What is a nanometer?

One-billionth the length of a meter is a nanometer. A sheet of paper measures approximately 100,000 nanometers thick. A single-walled carbon nanotube measuring 1 nanometer in diameter is 100,000 times smaller that a single strand human hair measuring 100 micrometers in size.

What is a patent?

Patents grant the inventor the right to use and own the invention. A patent prohibits others from using, making, or selling an invention in the United States after it is issued. The U.S. Patent and Trademark Office issues three types patents: Anyone who discovers or invents a new and useful machine, process, article, composition of matter, or other useful improvement in any one of these areas is eligible for a utility patent. 2. Anyone who invents an original and unique design for an article to manufacture is eligible for a design patent. 3. Anyone who discovers, creates, and asexually replicates a distinct and new plant variety is eligible for a patent. What year was the first US patent issued? Samuel Hopkins (1743-1818), a Philadelphian, was granted the first U.S. Patent on July 31, 1790 for “pot ash and pear ash”, a cleaning solution called potash. It was essential for making glass, dyeing fabrics and making soap.

What is Occam’s Razor?

Occam’s Razor, a scientific doctrine, states that “entities should not be multiplied beyond the necessary”. It proposes that a problem be described in its most basic terms. It states that the simple theory that best fits the facts of the problem should be chosen. William Occam (c.1248-c. 1348), an English philosopher, theologian. This concept is also known by the principle of parsimony, or the economy principle.

Which book is the most important and influential in science?

Isaac Newton’s 1687 book Philosophiae Naturalis Principia Mathematica (also known as the abbreviated Principia). Principia was Newton’s summary of his work. It covers almost all aspects of modern science and took Newton 18 months to write.

Newton defined gravity as a universal force and explained that the motion of a planet reacts to gravitational forces in an inverse proportion to its mass. Newton was able explain tides and the motions of comets, planets, and moons using gravity. He also demonstrated that the poles are where spinning bodies like earth, such as, flatten at the poles. Principia was printed in 500 copies at the first printing. The Royal Society had spent all its budget on a fish history, so it published the first printing at his expense (1656-1742).

What is the most frequently cited scientific journal article?

The most frequently cited scientific article is “Protein Measurement with the Folin Phenol Reagent” by Oliver Howe Lowry (1910–1996) and coworkers, published in 1951 in the Journal of Biological Chemistry, Volume 193, issue 1, pages 265–275. As of 2010, this article had been cited 292,968 times since it first appeared.
