what is speed of light |
March 18, 2013 |
| Author: namit |
|
|
i have heard that speed of light is a constant in a medium (ie when n remains constant) is this true ? and theoretically what we get as the speed limit is v<1/sqrt(mu * epsilon)now how do we know that c is the maximum limit ? CS: The expression you give is never larger than the speed of light in vacuum c. Just read volume 3, on electrodynamics! |

Iam a 61yo women who never got the chance to learn science of any description and with a deep desire to learn without the finances to back it up. I have just found your site and I feel like a young schoolgirl in love for the first time,so excited and yearning for more. Thank you from the bottom of my heart. CS: Enjoy it! |

Strand or String theory |
October 9, 2012 |
| Author: Rahul Kr Sharma |
|

I found these volumes recently on web and would take some time to go through them in detail. But a synoptic look at these books has given me an impression that these are going to be classics of our times. I have a question: in the final volume, strand theory is discussed. I have studied a lot about string theory. Is strand theory different from string theory. And if so, who has propounded the strand model. Thank you. CS: Volume VI tells it all; strands and strings have almost nothing in common. They differ in number of dimensions, in their particle model, in their description of gauge theory, in their approach to unification and in much more. |

Is weight of earth increases over period of time.doubt caught into my mind since population of humans have increased very much over centuries,on calculating average weight of a human as 40 kg,a comparable amount of weight is levied on planet earth.considering remaining being same for example buildings are build using cement,iron whose raw material is taken from earth itself. Is my doubt reasonable ? CS: Other effects on the mass of the Earth are much larger (meteorites, atmosphere loss, etc.) As far as I know, it is not even clear whether the mass of the Earth increases or decreases with time, because despite their size, the effects are still tiny compared to the mass of the Earth. |

I am nearly a senior in high school, and I've only ever taken the basest physics courses, yet you've made the concepts exciting and understandable to me. I believe the greatest turn-off of science to young minds is its predetermined dryness. I also believe that, for those who wish to learn, you have solved this problem. Thank you so much for creating these books for the pure intention of education. CS: All the best to you! |

if a smallest particle of our world like higgs boson fall into black hole, what will be happens with it? CS: It will be part of the black hole :-) |

Black Holes in Strand Model |
April 5, 2012 |
| Author: Umang Mehta |
|
|
Sir, suppose a group of particles, with total mass greater than Planck mass, gets compressed into a Schwarzschild black hole. Since a black hole has no strands in the interior, what happens to the tangle cores? Do they get untangled by any means? If yes, how? CS: A black hole can be seen as a giant tangle core. In detail, the various particle tangles spread over the surface of the black hole. By looking at the various tangles of real particles one can see that this can occur naturally, i.e., through fluctuations only. |

sir,if we are able to make the layer by electromagnetic field where light does not pass through it,then my question is:Will that layer become wormhole in space? because at that layer physics's laws will not valid at all CS: No, all of this is impossible. |

Please tell me the background of this very great project Sir! And why do you use the term motion mountain (it's sound classical while your book cover any frontier in the physics? Is there any possibility that you will translate into Bahasa Indonesia? Thank you very much for your effortless doing this available for anyone! Horas! From Indonesia. CS: See the "About the project" page and the first chapter of the book. The book indeed also covers the frontiers of physics - all of them. And if you organize a sponsor, I'll organize the translation into Bahasa Indonesia. Enjoy! |
