Physics --------------- ### The Trouble with Physics * rating: 1 I read this a few years ago and it is not bad. It asks some hard questions about where physics is going. ### The God Particle * rating: 1 I read this a long time ago. It's about the hunt for the Higgs particle. The viewpoint of an experimental (rather than theoretical) physicist is refreshing. ### thermodynamics - The Sun is giving us a low entropy, not energy - Physics Stack Exchange * rating: 1 . ### thermodynamics - Why does sunlight have low entropy? - Physics Stack Exchange * rating: 1 . ### Hans Grassmann - Contributions to physics * rating: 1 . ### mp.mathematical physics - Water at the scale of a cell should feel more like tar? - MathOverflow * rating: 1 . ### quantum mechanics - Have researchers managed to \"reverse time\"? If so, what does that mean for physics? - Physics Stack Exchange * rating: 1 . ### quantum mechanics - Can elementary particles be explained adequately by a wave-only model? - Physics Stack Exchange * rating: 1 . ### astrophysics - What is happening when magnetic field lines snap or break? - Physics Stack Exchange * rating: 1 . ### astrophysics - How do scientists know that distant parts of the universe obey the physical laws exactly as we observe around us? - Astronomy Stack Exchange * rating: 1 . ### audio - Why can so little digital information be stored on a cassette tape? - Signal Processing Stack Exchange * rating: 1 . ### thermodynamics - Placed in equivalent freezers, would a liter of water or a liter of lava turn from liquid to solid first? (question from a 6 year old) - Chemistry Stack Exchange * rating: 1 . ### fuel - Why do jet engines use kerosene rather than gasoline? - Aviation Stack Exchange * rating: 1 . ### Why do helicopters have skids? - Aviation Stack Exchange * rating: 1 . ### LHC machine challenges leading theory of physics - BBC News * rating: 1 . ### optics - What wavelengths of light does a banana reflect? - Physics Stack Exchange * rating: 1 . ### quantum mechanics - When will a wave function collapse if the observer was only a camera and the video was watched later in time? - Physics Stack Exchange * rating: 3 . ### power - If we increased the frequency of HV-AC lines, could we get atmospheric air to excite and illuminate? - Electrical Engineering Stack Exchange * rating: 1 .
