used in reference to a substance (often a particle) that has rest mass. Matter is also used loosely as a general term for the substance that makes up all observable physical objects.[1][2] All objects we see with the naked eye are composed of atoms. This atomic matter is in turn made up of interacting subatomic particles—usually a nucleus of protons and neutrons‚ and a cloud of orbiting electrons.[3][4] Typically‚ science considers these composite particles matter because they have both rest mass

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

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

CHAPTER I The PROBLEM AND ITS SCOPE INTRODUCTION Rationale of the Study Job satisfaction is simply how people feel about their jobs and different aspects of their jobs. It is the extent to which people like (satisfaction) or dislike (dissatisfaction) their jobs. As it is generally assessed‚ job satisfaction is an attitudinal variable. In the past‚ job satisfaction was approached by some researchers from the perspective of need fulfilment – that is‚ whether or not the job met the employee’s

Karla Alvarez Chemistry Period One Subatomic Particle The electron is extremely small compared to all the other parts of the atom. It is negatively charged. The negative charge balances out the positive charge of the protons in the atom. Electrons are found in the electron cloud that surrounds the nucleus of an atom. The clouds are generally organized into shells. Electrons move at a quick pace‚ so you never really know where they are specifically. But after years of doing experiments‚ scientists

“There are only two ways in which humankind can produce knowledge‚: through passive observations or through active experiment.” To what extent do you agree with this statement? Word count: 1255 Candidate name: Alexander Shum Candidate number: 0049330018 I fully agree the statement in the question. In my opinion‚ I believe that the production of knowledge requires both passive observation and active experiment. Both of them are heavily linked together‚ and are part of a larger process

Magnetic particle inspection (MPI) - Is a non-destructive testing (NDT) process for detecting surface and slightly subsurface discontinuities in ferroelectric materials such as iron‚ nickel‚ cobalt‚ and some of their alloys. The process puts a magnetic field into the part. The piece can be magnetized by direct or indirect magnetization. Direct magnetization occurs when the electric current is passed through the test object and a magnetic field is formed in the material. Indirect magnetization occurs
