A tsunami is formed when there is an earthquake, volcanic eruption or, more rarely, a landslide underwater. Typically, neither the earthquake, eruption or landslide are felt because they are so deep under water. However, the actions that have taken place are the first steps that lead to a massive tsunami that can cause tremendous damage to coastal regions. It should be noted that a tsunami and a tidal wave are different because they are not caused by the same thing. A tsunami, as mentioned above, is caused by earth quakes, Read More

Disabling Onstar is not a task that is as simple as pushing a button. Onstar is a device that permits the vehicle to be tracked and, if something happens to the vehicle, allows an operator to conact the vehicle. For some people, there is discomfort with Onstar having the ability to track the vehicle. To disable Onstar, it requires the device to be completely disconnected from the vehicle. Disabling Onstar Open the trunk and lift the liner that is over the spare tire. Place this to the side and remove Read More

Covalent bonds are bonds that occur during the chemical bonding of atoms of separate elements. Pairs of electrons share their energy in a way that helps to stabilize the atoms. This helps to attract and repulse atoms to one another and is a major factor in chemical reactions. Atoms share valence electrons with each other to form chemical bonds with other atoms. This allows atoms to bond together without having to be the same element. That is, the atoms only have to be within compatible electro-negativity. When these atoms have Read More

A Karnaugh map is a graphical method or shortcut that can be used to solve Boolean algebra problems. Boolean algebra is used to conduct computations and create expressions from two values. This type of math creates the basis behind much of computer science and modern circuit card design today. Maurice Karnaugh created the current version of the Karnaugh map in the early 1950s to solve logic problems without having to use long computations. What do Karnaugh Maps Do? Karnaugh maps solve problems through pattern recognition, not computation. They shift the Read More

A nuclear heart scan is an excellent method to evaluate the health of your heart. Nuclear heart scans are safe and extremely effective for diagnosing specific kinds of heart conditions. The process of having a nuclear scan is relatively simple and in most cases is painless. During a nuclear heart scan, a radioactive tracer (which is safe) is injected into a vein in your arm. This tracer circulates throughout the bloodstream and travels to the heart. As the tracer element circulates through the heart, special cameras scan the heart and Read More

A robot is a mechanical or virtual artificial agent that software, hardware, or firmware programming controls/guides. Most robots today are programmed to complete tasks on their own or via human direction. No longer a product of science fiction, there are a number of industries today that use of various types of robots. These include the medical, military, transportation, manufacturing, and space exploration fields. What Are Robots Used for Today? Robots are used for a variety of purposes in today’s society. Industrial robots have played critical roles in manufacturing plants since Read More

It used to be believed that light was simple energy and that there were no particles in it. However, with the study of the quantum, scientists were able to deduce that light was actually make up of small particles known as photons.Quantum optics is the study of light and its interactions with matter. More specifically, quantum optics is a field of study where scientists observe the nature and effects of light on photons that are being quantified. Understanding Quantum Optics Quantum optics is confusing to individuals for the simple fact Read More

A piezoelectric display is a display – such as on a mobile display – that can harden protectively when the device is turned off and soften into a touchscreen that, when pressed, can be depressed. In other words, it is a display that can change shape or texture based on whether it is on or off. While it has only been researched in previous years, it is suggested that this technology will make it to the forefront of mobile devices in the next year as well as future years. How Read More

What was once only a dream has now become a reality as space travel is a regular activity in our society. With thousands of satellites in orbit, the Hubble Space Telescope that can see other galaxies, regular shuttle launches, and prototypes for vehicles that can fly in and out of the atmosphere, it makes sense that we have a permanent space station in orbit. To fully understand the concept of a space station, however, it is important that people learn how a space station works. In this article, we will Read More

Cell phone radiation refers to the electromagnetic waves that cell phones produce and the user’s body, particularly the head, absorbs. Cell phone companies, research agencies, and other groups have known about cell phone radiation for some time. However, they have not yet found any conclusive evidence to show whether cell phone radiation does, in fact, cause harm to the human body. While conclusive evidence has not been found, there does seem to be some correlation between cell phone use and brain tumors, some forms of cancer, and blood flow problems. Read More
