Practical implication of anything divided by zero.

Hii,
This post is very special to me as I thought about this in 11th standard while reading my physics book.You will ask how it is related to physics.Well I am going to corelate the above question with physics.We all know that when a number is divided by smaller numbers the result is a big number and it tends to infinity when the denominator comes closer to zero.Okay now how can we relate this to physics.You all have heard about black holes.But do you know how they are formed.When a gigantic star comes to its end it shrinks into the space time fabric with its mass remaining same.As a result it gets penetrated in space time fabric and no one knows what happens henceforth.Similarly anything divided by zero is undifined and while solving it the whole number line will collapse to a point.This is the reason why I believe that black holes also get converged to a point that is the point of singularity.Hence for mathematics anything divided by zero is undefined.
Thanks....

Sci-fi WH

Hey all,  Consider two points A and B separated at a distance of say 5 cm in a piece of paper. If you were to reach point B from A you need to cover 5cm distance. But what if you wrap the paper in such a way that point A and B intersect. Then it becomes a shortcut right. This is exactly the concept behind worm holes. Due to the fabric nature of space-time this can be assumed that we can enter from past to future and vice versa through these holes known as worm holes created due to rupture in space time fabric due to movement of celestial bodies including planets. Time is a man made straight dimension but in our universe time is not moving forward rather everything is happening at the moment. It is like a 3hrs Bollywood movie being watched in a DVD where the time period for movie or event is fixed and we can go backwards and forward. Similarly events occuring in universe are fixed and we can rewind or move ahead using worm holes.  This concept is hypothetical based on journals ...

Resonant frequency

Hello physics lovers, All of you must have heard the word resonance once in high school physics books.If not then today you would know.Well we all know that any object having swinging motion will have a frequency associated with it.Not only swinging object but any sort of vibration or sound will have frequency.This means frequency can be Mechanical,accoustical etc.so frequency is nothing but number of oscillations made in a particular time,si unit Hertz.Now what happens is that when the external frequency applied on an object matches with natural frequency of that object it vibrates with maximum amplitude.It can be catastrophic in practical situations.This is the reason why a troop of army personnel having March on a bridge are said to walk abruptly without matching the March of other members.This is because if the frequency of the army personnel matches with the natural frequency of bridge it would collapse.You would be astonished to know while traveling if your heartbeat matches wi...

What happens when you leave your charger on after your phone is charged completely?

Hey guys, It's very common that we forget to switch off the main supply when our phone is charged.We leave it on.Now the question is whether there is any power consumption.Theoritically if there is no load there should be no power consumption.But still the charger consumes very minimum amount of energy because the primary winding of the transformer consumes electricity and this is the reason why the charger gets heated after some time.So if this thing happens for few times it's ok but if it is kept on for larger period of time then power consumed is considerable.So make it a habit to turn the mains off once your phone or laptop is charged up. Thanks...
