There’s currently no vaccine to prevent coronavirus disease (COVID-19).

You can protect yourself and help prevent spreading the virus to others if you:DoWash your hands regularly for 20 seconds, with soap and water or alcohol-based hand rubCover your nose and mouth with a disposable tissue or flexed elbow when you cough or sneezeAvoid close contact (1 meter or 3 feet) with people who are unwellStay home and self-isolate from others in the household if you feel unwellDon’tTouch your eyes, nose, or mouth if your hands are not clean

Upper-case delta (Δ) often means “change” or “the change in” in mathematics. … Given the quadratic ax² + bx + c, for example, the discriminant of that equation will equal b² – 4ac, and will look like this: Δ = b² – 4ac. A discr…

Beginning in the 6th century BC with the Pythagoreans, the Ancient Greeks began a systematic study of mathematics as a subject in its own right with Greek mathematics. Around 300 BC, Euclid introduced the axiomatic method still used in mathematics today, consisting of definition, axiom, theorem, and proof.

ArchimedesGreek mathematician Archimedes is widely considered by many to be the “father of mathematics.” He is regarded as one of the leading scientists in classical antiquity and is credited with designing numerous innovative machines, including the screw pump and siege engines.

Math seems difficult because it takes time and energy. Many people don’t experience sufficient time to “get” math lessons, and they fall behind as the teacher moves on. Many move on to study more complex concepts with a shaky foundation. We often end up with a weak structure that is doomed to collapse at some point.

It almost always means “and,” both in and outside of mathematics. * This symbol is called an asterisk. In mathematics, we sometimes use it to mean multiplication, particularly with computers. For example, 5*3 = 5 times 3 = 15. () The open (or left) and close (or right) parenthesis.

The “mean” is the “average” you’re used to, where you add up all the numbers and then divide by the number of numbers. The “median” is the “middle” value in the list of numbers. … If no number in the list is repeated, then there is no mode for the list.

As a result, he has been hailed as the first true mathematician and the first known individual to whom a mathematical discovery has been attributed. Pythagoras established the Pythagorean School, whose doctrine it was that mathematics ruled the universe and whose motto was “All is number”.

Zero and its operation are first defined by [Hindu astronomer and mathematician] Brahmagupta in 628,” said Gobets. He developed a symbol for zero: a dot underneath numbers.

When you first start up, Google Maps displays a satellite view of North America. You can then zoom in, or pan the camera around to see any location on Earth. You can also type in the address of the location that you want to see. Once you do that, you’ll get a free satellite view of your house.

Artificial satellites are used for all sorts of purposes. Satellites like the Hubble Space Telescope, the International Space Station, and the Russian Mir space station help scientists explore space in new and exciting ways. Communications satellites help us communicate with people all over the world.

Pakistan, which already had five satellites in space, lacks heavy duty launchers and satellite fabrication facilities. Scientists said it would also help Pakistan keep watch on India.

Technology can be most broadly defined as the entities, both material and immaterial, created by the application of mental and physical effort in order to achieve some value. In this usage, technology refers to tools and machines that may be used to solve real-world problems.

Technology is important because it makes you feel more secure with every area in life for both personal and business reasons. With technology advancing more people are able to have access to supplies such as fresh water and food because technology can help deliver those items to people that otherwise couldn’t get it.

6 Types of Technology You Must Know About

• Information Technology.
• Education Technology.
• Medical Technology.
• Communication Technology.
• Business Technology.
• Assistive Technology.

Technology can affect life both positively and negatively. New technology always changes our life very much and takes it to a new level. It is like the new way of thinking or doing the normal things differently, better and much more faster with less hassle and at a much affordable rate.

The so-called “Planet Nine,” as scientists are calling it, is about 10 times the mass of Earth and 5,000 times the mass of Pluto. Here’s the order of the planets, starting nearest the sun and working outward through the solar system: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune — and Planet Nine.

The International Astronomical Union (IAU) downgraded the status of Pluto to that of a dwarf planet because it did not meet the three criteria the IAU uses to define a full-sized planet. Essentially Pluto meets all the criteria except one—it “has not cleared its neighboring region of other objects.”

While most science fiction calls our sun Sol, and our system the Sol System, the International Astronomical Union (IAU), the body authorized internationally to name stellar objects, calls it “the Solar System”, and our sun, “the Sun”.
