Weather modification refers to willful manipulation of the climate or local weather. Research done in this field goes back to as far as the early 1940s when the US military experimented with cloud seeding to stimulate rain. Today, private corporations have joined the weather modification research effort to protect people, cities and assets from the …
Eddy currents are also referred to as Foucault currents and are created when conductors are exposed to a changing magnetic field because of a field source’s relative motion. Their applications include induction heating and non-destructive testing. Eddy currents are continually researched in order to develop new applications. How do Eddy Currents Work? Eddy currents are …
Room Temperature Vulcanizing (RTV) silicone is a rubber polymer used to create molds, prototypes, and sealant. It is extremely flexible and quite tear resistant. It is made up of two separate components: a base and a curative. RTV silicone can be poured, sprayed, brushed, or pumped onto a surface. Either moisture or heat dries it, …
Magnets are mainly characterized for having poles: if you put together poles of the same charge they repel and if you put together charges of different pole, they attract. A body will be under Magnetic Levitation when it floats due to that special repelling quality of the magnets, i.e. when the force generated by the …
The Parts of an X-Ray Machine There are three main parts of an x-ray machine. The first is the x-ray tube. This is responsible for the creation of x-rays. Therefore, without this functioning properly, there would be little chance for the x-ray to work in the right way. It generates enough x-rays so that when …
Sound is characterised as a series of waves that move through a particular medium. A medium is some sort of a subtance–whether it be water, plasma, air, a solid, or anything else–that these waves move through. The waves cause the particles in this substance to vibrate which is how the sound is potentially heard. A …
Potassium is an essential mineral that the body uses to perform various functions. The body naturally regulates the amount of potassium in the body to keep it in working order. This is done by the kidneys, the bowels and even natural processes such as sweating. Eating a diet which incorporates the recommended amount of potassium supplementation is best …
The Seebeck Effect was first discovered in 1821. It describes the thermoelectric phenomenon that results when the temperature differences between dissimilar metals in a circuit are converted into electric current. This is one of three similar processes that relate to conductivity, temperature, and thermoelectricity that was discovered in the 1800s. The Thomson Effect was first …
A nuclear bomb uses a nuclear reaction to generate energy (heat and radiated particles). The energy released is millions or in some cases billions of time stronger than TNT; the whole process is carried out in a very short time, providing huge destructive power. There are two types of nuclear reactions, fission and fusion. During …
The neuron is the cell responsible for the transfer of information and electrical impulses around the body. Neurons work by transferring electrical charges from neuron to neuron to get from one point to another. All data, therefore, is transferred in this electrical fashion which is why computer science has become such an important tool in …
