    Information in black hole is proportional to total number of microstates N in black hole. Other words, it is proportional to total energy of black hole divided by smallest possible energy which can exist in black hole:

    S ≈ k Etotal/Esmallest

    Let's explain it more detail.

    Most important step for understanding the information of black is to find smallest piece of energy which can be in black hole. The simple way present energy is presents it as photon ...

    A corrector will not keep its pristine appearance if used and we have to live with that fact.

    There are several different methods that are suggested on searches such as Windex, ASO etc, but I find that the method below does a good job.

    Before any cleaning takes place, make sure that the surface of the corrector has been blown off with an air bulb, not compressed air that may leave contaminates. Then carefully lift off other debris using a soft lens brush from a camera ...
