Following of our actions in our daily life are parts of physics study. 1) When we walk or run‚ our motion is part of laws of mechanics and thrmodynamics. 2) We eat food which undergoes chemical reactions producing heat energy which is converted into mechanical energy 3) Use of refrigerator‚ pressure cookers‚ washing machines‚ television‚ music system‚ computers‚ etc. are all designed on the principles of physics. 4) When we speak‚ we produce sound properties of which like pitch and

simple‚ elegant‚ revolutionary‚ and wrong. Well‚ "wrong" isn’t exactly accurate—incomplete or preliminary are better terms. The Bohr model was an essential step toward an accurate theory of atomic structure‚ which required the development of quantum mechanics in the 1920s. Even in its preliminary state‚ the model is good enough for many calculations in astronomy‚ chemistry‚ and other fields‚ saving the trouble of performing often-complex calculations with the Schrödinger equation. This conceptual and

As physical objects have wave-like properties (at the atomic level)‚ diffraction also occurs with matter and can be studied according to the principles of quantum mechanics. Italian scientist Francesco Maria Grimaldi coined the word "diffraction" and was the first to record accurate observations of the phenomenon in 1665. Richard Feynman wrote: [N]o-one has ever been able to define the difference between interference

Newton’s first law of motion which laid entire foundation for classical mechanics was named after English physicist Isaac Newton who introduced this great theory in 1687. As we all know‚ prior to Newton there were some other predecessors of note who contributed to inquiring the relationship between a body and the forces acting

Stephen Hawking was born on 8 January 1942 to Dr. Frank Hawking‚ a research biologist‚ and Isobel Hawking. He had two younger sisters‚ Philippa and Mary‚ and an adopted brother‚ Edward.[11] Though Hawking’s parents were living in North London‚ they moved to Oxford while his mother was pregnant with Stephen‚ desiring a safer location for the birth of their first child. (London was under attack at the time by the Luftwaffe.)[12] According to Hawking‚ a German V-2 missile struck only a few streets away

stories that are called “Popular Mechanics” by Raymond Carver and “Lamb to the Slaughter” by Roald Dahi. These stories aren’t just ordinary stories that we read everyday no these two stories have a big twisted into it. Instead of having a happily ever after you get a shocking and horrifying ending. What connects these two stories is that their both short stories and the author in both stories want the readers to guess what happens in the story. For “Popular Mechanics” is by Raymond Carver‚ who made

the universe has a force that attracts each other. Something else the world would have never found would be my laws of motion. The laws of motion gave people a better understanding regarding movement which helps people today in space travel and mechanics. The world would be a better place without John Locke for many reasons. One good reason would be that if he didn’t exist there wouldn’t be a lot of abortion issues around the world and especially in the United States. The reason why there are a
