The energy of the sun is one that holds the responsibility of the air movement. Moving air is known as the wind and it has the kinetic energy. 250 years ago, windmills have been invented by the Persians and they are gaining much of popularity. The modern windmills convert the wind energy into their mechanical […]

A model that shows molecular structure of DNA was proposed by Watson and Crick in 1953. Two polynucleotide chains operated in antiparallel direnctions in a DNA molecule. They form a spiral helical structure by twisting around each other. A phosphor-diaster bond links a nucleotide to another. Two adjacent nucleotides are separated in a distance of […]

Do you know what a solar cell is? Well, it is a device converting the solar energy straight into the electrical energy. Previously, it has been observed that, when the solar rays fall of into the thin wafer of the selenium, the electricity will then be generated. On the other hand, a solar cell being […]

Solar cooker is a type of home appliance that uses the heat of the sun in order to cook food. Being shown into the figure, this appliance consists of a container box in which its body is made up of a non-conducting plastic of the fibrous material and then insulated from the outside to avoid […]

Magnetic resonance imaging which is also called MRI is a diagnostic imaging technique which produces 3D images of internal body parts. Human body contains 70% water inside it and these water molecules have H+ atoms inside them. The Hydrogen (H+) atoms contain nuclear magnetic resonance (NMR) signal inside their nucleus. Therefore MRI is used to […]
