### Working on ERP is challenging

Working on ERP is challenging Why it is challenging? you will know by my following decription. This time I am working in Mumbai . That company have lot of project and technical persons for development works are very less. I am already alloted for...

### How an inductor works?

How an inductor works? The inductor is behaving the way it does? Assume that we are applying a DC voltage across its terminals, no current passes through it initially, then after some time it starts building up. In case of inductor the produced...

### Mass of our body

Mass of our body Mass is the amount of matter present in our body rite and mass doesn’t change with place, it’s constant. The thing which we actually measure in the weighing machine at home, dispensaries etc is our mass actually than how the...

### Matter waves

Matter waves. The formula for wavelength of matter wave is. w=h/p. Where 'w' is wavelength 'h' is Planck's constant & 'p' is momentum of a particle. if my particle under observation is at rest with respect to me , (i.e. 'p'=0. 'w' is infinite)...

### Bermuda Triangle.

Bermuda Triangle. There are many theories some are below. 1. Due to extra magnetic field. Since it is located at center of the earth it can attract any material above it even an aero plane! Even a compass can be destroyed if we get anywhere near...

### Concept of universe

Concept of universe Just as an egg has a development phase, similarly our universe also has a development phase. Like the different body parts which are developed in the egg of the chicken, similarly different solar systems are being developed in...

### The size of our Earth

The size of our Earth The radius of Earth is 6371 km and the radius of Earth Venus is 6051 km. Venus is the only planet that rotates Westwards and Earth and rest of the planets rotate West to East Venus also rotates eastward. But its rotation...

### Can nuclear fusion ever be possible?

Can nuclear fusion ever be possible? The world faces a grave energy crisis. Nuclear energy is the ultimate key. Can scientists bring together a solution to this problem? Conducting a nuclear fusion reaction is possible, but there is a problem in...

### Does really time travel exists?

Does really time travel exists? Is it true we can reverse the time? I have heard about different theories on time travel- parallel universe, the theory that revolves around speed, etc. It is actually possible due to the introduction of Worm Holes...

### What is time?

What is time? Actually there are two theories related to born of the universe. First is well known big bang which tells that universe was a sphere at start and after big bang it started expanding and will keep expanding till its end. And another...

### Why the friction is nil in rolling friction?

Why the friction is nil in rolling friction? Friction is nil in pure rolling motion on a horizontal surface. Suppose friction were acting on a sphere in pure roll on a horizontal surface. If it's direction is such that it increase velocity of mass...

### Big Bang Experiment

Big Bang Experiment Objective of the experiment, it has no a single objective. All the mass and the energy present in the universe was supposed to be present as small point. During the earlier seconds of the big bang it busted and the universe...

### Super conductors

According to london's first equation,electrons continously accelerate,when electric field is applied across a conductor,this way electrons can acheive speed greater than that of light,but a particle can't acheive speed greater than light. In free...

### Potential of earth

What are the arguments that support assumption of potential of earth to be zero. According to the definition of potential of earth work done to bring a particle from infinity to a place. Considering earth work to bring particle from earth to a...

### Chemistry Jokes

Chemistry Jokes Just graduated Chemist after his graduation bought a big bottle of alcohol to celebrate his graduation with the friends in his home-village. On the way he had to go to the bathroom and did not know where to live the alcohol; after...

### Gravity and anti gravitation

Gravity and anti gravitation Gravitation is nothing but a force commonly known as "gravitational force". A body attracts another body if they are having a potential difference; potential difference is also a form of energy. If both the potential...

### Collision

Collision What happen when two electron collide with each other with the velocity of light? Electrons will not travel with the velocity of light. Only light travels at that speed but it not required dat electrons travelling with velocity =c....

Hawking radiation As we know, a particle-antiparticle pair is sometimes created near the event horizon of a black hole. Why is it that the antiparticle falls into the black hole and the particle moves away from it? What is the determining factor...

### Definition of Force.

Definition of Force. Force is some natural phenomenon that changes the state of the motion of the body that is it accelerates the body. Now let us define a unit of Force arbitrarily (e.g. a standard spring being stretched 1 cm under elastic limit...

### What is randomness?

What is randomness? I want a good physical understanding of randomness. Is there something really random? Classically when we say the event is random. We usually do so because we don't know the exact information. Are we known that there was a...
