The photon saga. 2

5. Photon is a zero mass particle (not a zero rest mass particle) and its deflection in gravitational field, called gravitational lensing is due to two reasons; i. single photon effective mass is due to the definite energy and momentum of the same. ii. multiple photons have non-zero invariant mass, hence they behave like any ordinary particle with mass, bends under gravity therefore, in both cases.

6. talk about inertial or non-inertial frames hardly does complicacy (unless its a particle with mass, hence further degrees of trade-off in phase space) especially if you are dealing in terms of energy and not force etc. Which is why Physics is formulated on higher parameters like energy and action, from where these concepts do not make difference. Energy is already integrated and having an acceleration on every instant has already been taken into consideration.

I THINK THATS ENOUGH FOR YOU TO REMEMBER ABOUT PHOTONS FOR NOW. IF I STUMBLE ACROSS ANY MORE CONFUSION WE WILL DISCUSS MORE. More…

Status of my websites. Reply

I do not have any more websites except perhaps tumblr which I haven’t visited for months its a free site and mapped from other websites. Social media is a dependent on our free labor and makes us work hard for it, but has been somewhat useful for publicity of my websites. If you have liked reading stuff say yay.

The principle of equivalence as Einstein knows it was also how Galileo would have !! Reply

The principle of equivalence as Einstein knows it was also how Galileo would have known!!

In a recent (although not quite quite recent) I wrote an article of how the concept of “Principle of Equivalence” is fairly misunderstood and misrepresented. In that or a related article the proof that the PoE (of GR as is usually said) follows from Principle of Least and/or Stationary Action (PoSA) was performed by me. (like a bolt from sky, I thought it, proceeded to prove it and it happened, which is why I am often a fan of making outrageous comments in Physics and most times they turn out true as far as I know, but sometimes grave silly mistakes might occur which obviously I own up but do not stick by, in other words would correct as soon as I would spot them or as soon as I can review and fix them) I also stated that PoE is directly related to Energy Conservation Principle (perhaps for the reason of PoSA, as PoSA is the central formalism of all of Physics, including QMech) That later is also obvious from the fact that PoE is actually a statement that KE and PE are but the equivalent forms of energy. The amount are not equal but equivalence means some part of one (A) is equal to another (B) in that scale, for all parts of one (A) or the other (B). More…

What to do if you have diabetes !! Reply

So I walked, regularly, ate healthy and making sure not jumping 800 calorie except exceptionally and slept well and in time and in 2 weeks my fasting level saw a drop of 130, back to the level of normal. I planned to check it sooner but haven’t been able to, although its less than 4 weeks since I last tested normal. So I will soon do that. If you have diabetes or someone who you know does you can explain him this or pass this if he is capable of reading this.

Thanks. More…

Intelligence and IQ Reply

Intelligence is our response to a given situation where the outcome is to be apprehended and measured against our preconceived notions. Its widely subjective even when there would be consensus about the outcomes. eg falling on a floor due to slipping is not too intelligent and dancing properly isn’t achieved by all. But there is consensus that one has to stand stable and thats intelligent. What if the situation is different and dynamic one may and a big fraction may fall. Its that spur of the moment response and success thats a measure of our intelligence among other variables such as physical dexterity. SO mental intelligence as opposed to physical intelligence (eg Hawking has to be intelligent but only mentally intelligent but an acrobat could be both physically and mentally intelligent to varying degrees) More…

Concept of contra-variance and co-variance tensor !! Reply

Co-variance: variance/change in direct-accordance with the change in x-coordinate. For a vector transformation its always the vector index which is summed up with the x-coordinate index. hence when x-coordinate change is direct with the vector-transformation the x has to be in the numerator. This is co-with-x. Or direct proportionality. Also since x and vector index is summed over the resultant vector index is the z or y coordinate’s index. That means that remaining index shows up on the resulting vector. That index occurs on z/y etc which is in the denominator. That means a co-variant vector and tensor (tensor is more than one vector multiplied) has its index on the subscript of the vector or tensor. And this index is of y/z etc. More…
