A Geiger Counter is a device that is used to detect radiation. The device needs careful handling as it is a sensitive instrument. In addition anybody dealing with radiation must take precautions so that he or she does not come in contact with radiation or its source. The basic aim of the Geiger Counter is detect radiation by the ionizing effects radiation creates.

In the study of motion, there are two quantities we should understand, these are the scalar and vector quantities. A scalar quantity is described by its magnitude only while a vector quantity has both magnitude and direction. Force, velocity, acceleration, displacement, and electric field are vector quantities. Speed, distance, mass, volume, time, density are some examples of scalar quantities. The objective of the experiment is to determine the direction of the resultant force of a simple force...

The earliest sources of magnetism were magnets such as the famous loadstone of Magnesia. Many scientists began investigating the properties of magnetism associated with electric currents when they discovered that a compass needle is deflected by an electric current. One of the objective of this experiment is to differentiate magnetic induction from magnetism. Continue reading to know more.

Modern airliners have complex avionic systems. These need to be monitored for proper efficacy. This is done by Numerik Control systems called open and closed loops. These are important because of the power electronic on board. The open and closed loops systems help compare the operating parameters of the aircraft

This article will teach you some basic knowledge about quantum physics. Many different complex mathematical and scientific terms are used in this article. The article will teach you about Steven W. Hawking's research and ultimate goal in life. You will learn how the magnitude of his disease has limited him to a wheel chair.

Almost everything around you can be measured. The clothes you wear, the food you eat, the distance between two planets or even the width of a bacteria can be measured. Physics as a science involves measurement. By measurement, we mean comparison with a standard. One of the objective of this experiment is to measure the length of some objects accurately. And to know the relationship of the metric system to English system of units.

Mathematica has a beautiful implementation of graph plotting which is used worldwide by scientists, students, engineers in various fields of their work. Multiple graph plotting, piecewise graph plotting, manipulation of a plot, parametric graph plotting, graph plotting by importing data from a file etc. can be done very easily in Mathematica.

The existence of Majorana Particles was predicted in 1932. They remain elusive even 70 years after scientists started looking for them. It seems that finally they were discovered in February 2012. If confirmed, these particles might play a substantial part in the development of Quantum computers. This article explains the subject to the layman.

Radiation is a common word that we are all familiar with. What we think radiation is can be different in the science world. Radiation is a mechanism of transfer of energy of different types. We have heat radiation, photon radiation, etc. The object projected by the radiation would absorb the energy and thus explains certain phenomena in our surroundings. There are different concepts under radiation. This science is so vast that it has grown into a field.

Vega completes the three-rocket complement of ESA launch vehicles. Primarily designed for cost effective access to space, Vega is designed to launch those satellites ranging from 300 to 2000 kg. Its primary purpose is to reduce the cost of space missions by creating a light-weight medium payload rocket, as well as, keeping the high-tech space program within the European economy.

Have you ever wondered why you are safest in a car when out in a thunderstorm? You may have thought that it is the rubber tires that protect you, and that might be partly true. Tires are a fairly good insulator. However, the reason that you are safe in a car is due to the law of Faraday’s Cage.
