Galileo Galilei was the founder of modern physics. To assess such a claim requires that we make a giant leap of the imagination to transport us to a state of ignorance about even the most elementary principles of physics. Today, the simple laws of motion as defined byIsaac Newton, for exam...

The goal of this study was to elicit and juxtapose the account of the concept of weight in history vis a vis physics education. The results reveal the prob
In this study we are using the new technique of extraction where the extraction is performed atraumatically using the physics forceps , by using a single first class lever, creep,stressdistribution,rather than squeezing and pulling the alveolus. Two patients indicated for extraction of their badly ...

If we had all the formulas for all kinds of energy, we could analyze how many processes should work without having to go into the details. Therefore conservation laws are very interesting. The question naturally arises as to what other conservation laws there are in physics. There are two ...
