Instruments and processes that use physical methods, or were created or discovered in physics labs, have wide uses outside them such as the range of imaging techniques that have revolutionized medical practice. Physical theories can also provide tools or conceptual frameworks that support other sciences or technology: quantum theory is necessary for applications of light and lasers and for nanotechnology; the complex theory that describes the motion of liquids and gases underpins meteorological forecasting and climate modelling; and quantum computation has implications for national security.","PeriodicalId":301418,"journal":{"name":"Physics: A Very Short Introduction","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115692131","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It discusses how through processes of observation, recording, experimentation, and analysis over millennia in different nations and cultures, modern physics has evolved, and highlights some of the key stages of that evolution.","PeriodicalId":301418,"journal":{"name":"Physics: A Very Short Introduction","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133983356","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is concise and seemingly clear, but physics is a sprawling and dynamic science and this basic definition needs to be amplified to truly reflect what physics is all about. ‘What physics covers and what it doesn’t’ considers the different meanings of matter and energy; and also explains how physics can be defined and described by scale, and how it deals with different aspects of the universe by their size. From quarks to atoms to galaxies, the components of the universe span many orders of magnitude in size. The different sub-divisions of physics are also considered.","PeriodicalId":301418,"journal":{"name":"Physics: A Very Short Introduction","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115277830","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
