Polymers as An Example of Chemistry Applications in Our Lives
Last Updated on June 20, 2022 by Mostafa Chemistry is a natural science that has existed since ancient times. Chemistry applications in ancient civilizations have been linked to mining, dying, medicine, and glassmaking. civilizations, including the ancient Egyptian, Babylonian and Indian, succeeded in using chemistry in practical ways in those fields, but they did not develop theoretical knowledge that could be considered a science. The seventeenth century witnessed the beginning of modern chemistry, when Boyle conducted his research on the elements, Joseph Priestly recognized oxygen gas, Henry Cavendish discovered the composition of water, and John Dalton developed the modern atomic theory. Chemistry is the science of matter and the study of the properties, structure, composition, behavior, interactions, and variables of matter. Chemistry is related to different branches of science, including physics, astronomy, geology, and biology. In the present era, there are many chemistry applications in life.

The Importance of Virtual Labs and Simulation Systems for Educational Institutions
Last Updated on June 7, 2022 by Mostafa The virtual labs use a teaching method called simulation. The simulation, as defined by Dr. Ali Abdul Samia Quora, is an educational method that the teacher usually uses to bring students closer to the real world. The simulation method is believed to be closer to what is happening in areas that do not accept the lowest percentage of error, such as nuclear industries and some military industries. Simulation is one of the most important methods of education and training that trainers rely on to rationalize financial costs and also to rationalize time and effort. The simulation serves many educational objectives such as “goal of acquiring skills” in an environment similar to reality, and also serves the “cognitive goal” as it helps the learner to gain a lot of knowledge about the real work environment and its requirements. Simulation in Education After the spread of computers in the mid-nineties of the twentieth century, interest in simulation as an appropriate and effective in the process of education has increased. Simulation has become more effective and exciting in teaching. Simulation languages have varied and the material losses reduced adding flavor of fun to the …

Virtual Reality: It’s Past, Present and Future
Last Updated on February 21, 2022 by Mostafa Virtual Reality (VR) is defined as a 3D interactive environment designed by computer programs and it is linked to virtual reality glasses. The VR surrounds the user and transports him into a virtual world that seems real. VR may be a fantasy or an embodiment of the real world, and we can deal with this VR through the interactions between the virtual environment and the user’s senses and responses. The technique of VR is divided into two different forms: The first is through the use of self-operated glasses without using the smartphone, and the other form is the glasses that need a smartphone to work, which is the most widespread form today. The emergence of virtual reality: In 1936, Gernsback designed, TV goggles, or Tele iGlass, a pocket-sized portable battery-operated TV with a separate screen for each eye; much like the 3D virtual reality glasses now. At that time, the device presented an experiment described by ‘Life’ Magazine as “one of the new Mars experiments.” Those glasses, weighing just 140 grams (less than a third of a pound), contained small tubes of cathode rays and a pair of antennas (such as those …
