Time dilation: Energy slows down clocks … (Newtonian time dilation) 1

All energy slows down clocks …, not just gravitational energy and there is nothing Einsteinian about it. Gravity just slows down in a particular way than any other forms of energy and Einstein gave its exact form. I will derive time dilation of gravity from Non-Einsteinian case. More…

Gravity warps space-time !! 1

Since flat space-time can be thought of in Newtonian mechanics as an absence of force or potential of gravity, the presence of such forces is ipso-facto a curvature of space and time, therefore space-time. Thats just another two lines to prove what I claimed, ideally and intuitively. More…

Since flat space-time can be thought of in Newtonian mechanics as an absence of force or potential of gravity, the presence of such forces is ipso-facto a curvature of space and time, therefore space-time. Thats just another two lines to prove what I claimed, ideally and intuitively.

” eg when earth occupies the space-time around it, its effect, interaction or force is larger at a distance which is closer to the surface and smaller at a distance which is farther away, the force decreases radially-linearly, not linearly as such. So there are equipotential surfaces of gravity which are merely concentric spherical enclosures, one at each value of r=distance. This is tricky because its a potential energy where the reference can be chosen arbitrarily in a given situation. In other words, potential energy being negative, its the absolute or modulus of the energy we are talking about. In essence this is to say, the force without the direction specified.

Its interesting to note, thats so because force is a vector and associated with direction and energy being an integral of force, energy has to go on decreasing if energy continues to produce a force. This is again similar to a situation where like a bank account, the more time you spend in a pub the more you have to spend. ” More…

My vision for India’s education. Reply

This failure is primarily because of a paradigm shift that India hasn’t yet fully realized. The achievement of international standard needs to be a national effort to lead towards international standing, NOT a branding phenomena. The “Nobel” efforts such as that of Rabindranath Tagore and CV Raman are respectable, but they could NOT meet the demands of an international dream that India has discovered for itself in the last decade.

Future is therefore “gleam” unless truly national effort of international nature (read international effectiveness) is realized in the next 5 to 10 years. The IITs and BITs and IISc are reputed organizations, but haven’t kept up with a national dream, so they can not run into the international miles. The new names such as Nalanda and Vedanta University are either in their metamorphosis or strangulated in sightless paranoia. More…

Opinions on exorbitant cost of educative materials. 1

I can’t understand why the books are made so much expensive. Sometimes, I wonder whether they really want profit, or they just want that no one reads these books. They claim that the Author has put so much work and he should be paid for this. But I think if the price of the book is reasonable many people will buy and this way the profit will increase more and also they can satisfy their soul that they are spreading knowledge. In fiction, I can agree that the author put many imagination.

But in Science, most of the books [almost all in this era] are not the work of just one person but of many people and if we think logically, it is the research done on Millions of Dollars of [$] tax money by the society. So, the science doesn’t belong to a few persons but to the society as a whole and books are a way to return back value to them. I agree that authors need to be paid but if the books price is so high then who will buy them. More…

a simple calculation for earth spin projected onto sun-earth orbit plane. Reply

Here is the earth-around-sun and earth-spin situation:

Earth rotates around sun in a tilt of 23.5 degrees and earth rotates around itself with spin S. SO S is 84% along sun’s vertical and 16% along sun’s horizontal; More…
