The Types of Robots

Robots on Earth

They lift heavy objects, paint, handle chemicals, and perform assembly work. They perform the same job hour after hour, day after day with precision. They don't get tired and they don't make errors associated with fatigue and so are ideally suited to performing repetitive tasks. The major categories of industrial robots by mechanical structure are:

Religious Affiliation of History's 100 Most Influential People by Michael H. Hart

This list of names and their ranks are solely the work of Michael H. Hart. The columns "Religious Affiliation" and "Influence" are the work of Adherents.com. We will readily modify notes if there are any inaccuracies.
Note that many influential philosophies (such as Marxist Communism or Confucianism) are not always

what is meteorite?

This article is about debris from space that survives impact with the ground. For other uses of "Meteor" and "Meteors", see Meteor (disambiguation). For popular applications, see Falling star. For the fictional superhero in the Marvel Comics universe, see Meteorite (comics).

More generally, a meteorite on the surface of any celestial body is a natural object that has come from elsewhere in space. Meteorites have been found on the Moon and Mars.A meteorite is a natural object originating in outer space that survives impact with the Earth's surface. Meteorites can be big or small. Most meteorites derive from small astronomical objects called meteoroids, but they are also sometimes produced by impacts of asteroids. When a meteoroid enters the atmosphere, ram pressure (not friction) causes the body to heat up and emit light

lunar eclipse

A lunar eclipse occurs when the Earth's shadow falls on the Moon, and a solar eclipse occurs when the Moon's shadow falls on the Earth. A look at the geometry ofMoon phases would make it appear that a lunar eclipse should happen at every full moon and a solar eclipse at every new moon. This does not occur because the plane of the Moon's orbit is tilted 5.2° with respect to the plane of the Earth's orbit around the Sun (the ecliptic plane). The conditions for eclipses occur only at the points at which the Moon's orbit passes through the ecliptic plane.
These illustrations are not to scale and of course greatly exaggerate the 5.2° angle of the Moon's orbit with the ecliptic, but conceptually they show the conditions for eclipses. They were inspired by illustrations in Chaisson and McMillan.
This view of the Moon's orbit helps to explain why you don't get a lunar eclipse every full moon, but only about every six months when the Earth, Moon and Sun line up on the line of nodes.

the conditions of solar eclipse happen

Solar Eclipse

A solar eclipse occurs when the Moon's shadow falls on the Earth, and a lunar eclipse occurs when the Earth's shadow falls on the Moon.
The image below is a modified version of a GOES weather satellite picture taken on July 11, 1991. A solar eclipse was occurring near the Baja Peninsula of Mexico.

The image was lightly colorized to emphasize the location of the shadow, but it gives a perspective of the size of the Moon's shadow on the Earth.

A look at the geometry of Moon phases would make it appear that a solar eclipse should happen at every new moon. This does not occur because the plane of the Moon's orbit is tilted 5.2° with respect to the plane of the Earth's orbit around the Sun (the ecliptic plane). The conditions for eclipses occur only at the points at which the Moon's orbit passes through the ecliptic plane.The illustration below is not to scale and of course greatly exaggerates the 5.2° angle of the Moon's orbit with the ecliptic, but conceptually it shows the conditions for eclipses.

Do You Know Cyber Crime ?

The internet in India is growing rapidly. It has given rise to new opportunities in every field we can think of – be it entertainment, business, sports or education. There are two sides to a coin. Internet also has its own disadvantages. One of the major disadvantages is Cybercrime – illegal activitiy committed on the internet. The internet, along with its advantages, has also exposed us to security risks that come with connecting to a large network. Computers today are being misused for illegal activities like e-mail espionage

7 Negative Effects of Facebook

In the level of 1 to 10, how much do you like Facebook? If you put yourself in the scale of 7 or even more, such as 10, you better think twice. Why do you have to think twice? It is because Facebook has negative effects, apart from the positive sides. Maybe you will ask, “What are the negative sides of Facebook??!” We will give you the answers inside this article.

So many Facebook users, especially teenagers do not realize the negative effects of Facebook. Is it because they are already addicted to Facebook? If they are, as we already know, addiction may lead into negative things if we cannot control it.
