How do you prepare for the International Physics Olympiad?
Thanks for the A2A!Prior to three months before the Olympiad:Learn the theory: this includes Mechanics, Electromagnetism, Thermodynamics, Waves & Oscillations and a little bit of Special Relativity and Quantum Mechanics. Furthermore, you will be needing to know basic Calculus — at least, integrating and differentiating basic functions. Here are the books you can prepare with: Mechanics and Special Relativity: An Introduction to Mechanics: Daniel Kleppner, Robert Kolenkow: 9780521198110: Amazon.com: BooksElectromagnetism: Electricity and Magnetism: Edward M. Purcell, David J. Morin: 9781107014022: Amazon.com: BooksThermodynamics: Use the corresponding chapters in “Feynman lectures”.Waves & Oscillations and Quantum Mechanics: Use the internet. Most books I have seen in these topics are much more detailed than you need for IPhO.Solve problems: Here is a secret: without solving problems, you are not going to learn… how to solve problems! Solve as many difficult problems as you can with deeply and thoroughly understanding the concepts. Irodov is as good a book as any.Last three months:Okay, you mastered the concepts behind general physics and solved problems. Now, it is time to work on your time-management and Olympiad-writing experience.Write prior IPhO and APhO papers in test conditions: Sit down. Keep a snack with you. Put a timer in five hours. Be in an environment where there is absolute silence. Start writing for five hours. When you finish, have a rest. Later, take the solutions of the problems and start checking your work. Try to understand your mistakes thoroughly! Go deep to the concepts.Do laboratory experiments: Ask your teachers to provide you with laboratory experiments. Most countries have bought prior IPhO experimental equipment with them. Do as much experiments as you can.Last week:Relax! You did everything you could and working for a week is not going to change anything. Have fun with your friends, socialize, play sports, call your girlfriend!
Help in history!?!?! (World War II and I) Few questions i need answering please...!?
WW1 happened because of the expanding imperialist countries. Major countries like France, Austria-Hungary, and England. They all wanted more land and resources to become even more powerful. The Nazi party is the National Socialist Party. They believed in a strong government and promised to turn Germany back into a world power. Communists believe in a form of government called communism. Communism has the idea of equality for all and ownership for all. While this idea sounds great on paper, it will never work because of people's greed. The French and British created the Treaty of Versailles. It was a harsh treaty that forced the Germans to pay reparations to Great Britain and France. Hope this helps. Good luck.
