The blue light (on LED screen in most mobile phone, iPad, LED TV) is bad for eyes. Put a layer of blue-light screen protector (S$30) to protect eyes. In 1973 A-Level Physics we studied “Black Body radiation”, Planck’s Constant … and the famous formula E= ħν but did not...
The analysis of circular motion in terms of these laws yielded a formula of the quantitative measure, in terms of a body’s velocity and mass, of the centripetal force necessary to divert a body from its rectilinear path into a given circle. When Newton substituted this formula into Kepler’...
physics is one of the most interesting subjects which is filled with numerous engaging concepts. the concepts taught in the 10th standard are the fundamentals of the subject. students must learn these concepts in-depth to develop their skills in the subject and build a strong foundation. watch ...

A Shaky Foundation: New studysheds more lighton what caused London's Millennium Bridge to wobble. Pedestrians don't necessarily need to synchronize their gaits to cause shaking. Bonus: the physics of how Death Eaters destroyed the bridge inHarry Potter and the Half-Blood Prince. ...
The temperatures, measured by Raman thermometry under conditions identical to those of the present HHG experiments, range from ~300 K at the top to ~255 K at the bottom of the first sheet, translating to a density variation of close to 5% (Fig. 4b) for ethanol41. Over this range ...
英语翻译You must fix in mind the symbols and formulae,definitions and laws of physics,no matter how complex they may be when you come in contact with them,in order that you may understand the subject better and lay a solid foundation for further
Newton’s Laws of Motion laid the foundation for classical mechanics today. Although subject to minor limitations, these laws of motion are valid everywhere and are therefore used. The laws are given as stated below in a brief description ...
