String Theory Essay Man has always had many questions regarding his surroundings. We are always curious to answer many unknowns and many will remain unanswered‚ but what if there was a theory that would allow us to explain at least all of nature’s forces within a single all encompassing coherent framework. What does this exactly mean? Well‚ explaining the universe in the most intricate and basic detail so one can stand in awe of its beauty and elegance. There is an idea floating around these days

institute. 1. Two particles‚ P and Q‚ of mass 2 kg and 1.5 kg respectively are at rest on a smooth‚ horizontal surface. They are connected by a light‚ inelastic string which is initially slack. Particle P is projected away from Q with a speed of 7 m s-1. (a) (b) Find the common speed of the particles after the string becomes taut. Calculate the impulse in the string when it jerks tight.

What happens when the irresistible force meets the immovable object? One of the more convincing solutions has been proposed by Gary V. Smith of Aston University. He explained it as so: “The initial step to answering the superficially paradoxical question of “What would happen if an unstoppable force met an immovable object?” is establishing what is meant by ’immovable’. In order for something to move‚ its position must be measured relative to something else that is not moving. The universe

a specific charge. Up quarks carry a positive two thirds charge (+2/3). Down quarks carry a negative one third charge (-1/3). Electrons carries a ‘whole’ negative charge (-1). Depending on how these three quarks are arranged‚ you can arrive at a particle with no charge (neutron) or a whole positive charge (proton). Protons are made of two up (+2/3) + (+2/3) =+4/3 and one down (-1/3) quarks. Combining the third charge of the down quark means you take the negative charge from the positive charge

The Nobel Prize in Physics 1968 was awarded to Luis Alvarez "for his decisive contributions to elementary particle physics‚ in particular the discovery of a large number of resonance states‚ made possible through his development of the technique of using hydrogen bubble chamber and data analysis". Alvarez’s colleagues sometimes called him the "prize wild idea man" because of the huge range of his activities. He did all kinds of research into the atomic nucleus‚ light‚ electrons‚ radar‚ and so

Thus the end result of diffusion would be a constant concentration‚ throughout space‚ of each of the components in the environment. The particle theory states that matter is made up of tiny particles that are in constant motion and are held together by very strong electric forces. The state that the matter is in determines how quickly diffusion will take place. Gas particles have the most energy
