You have classical physics (before the 1900s) and you have modern physics (after 1900).  Modern physics is when Einstein developed his E = mc^2 theory.  He and several other scientists of the time developed quantum physics to answer questions that classical physics couldn't answer.  When a quantity is quantized it means that it is converted from the classical quantity to the quantum quantity (involves complicated math).  This is a quick version answer to your question.  Hope it helps.\n\nG

There are many undetermined ( not undefined ) mathematical quantities such as :\ninfinity - infinity\ninfinity / infinity\nzero / zero\nzero ^ zero\nzero * infinity\nas an example : (0^2)^0 = 0^0\n                (0^3)^0 = 0^0\nis that mean that 2=3 ?\nSo 0^0 is an undetermined quantity\nregarding that zero can be considered as the smallest +ve quantity we can ever have or the biggest -ve quantity we can ever have

It's a way of expressing something in unitless terms.  Very important for statistics and probability.  Also useful for comparing two numbers of the same unit.

A DERIVED quantity is a quantity related to another quantity set. It can be a child parent relationship or a parallel relationship.

Quantum physics is the study of the behavior of matter and energy at the molecular, atomic, nuclear, and even smaller microscopic levels. In the early 20th century, it was discovered that the laws that govern macroscopic objects do not function the same in such small realms.\n\nWhat Does Quantum Mean?: "Quantum" comes from the Latin meaning "how much." It refers to the discrete units of matter and energy that are predicted by and observed in quantum physics. Even space and time, which appear to be extremely continuous, have smallest possible values.\n\nAs scientists gained the technology to measure with greater precision, strange phenomena was observed. The birth of quantum physics is attributed to Max Planck's 1900 paper on blackbody radiation. Development of the field was done by Max Planck, Albert Einstein, Niels Bohr, Werner Heisenberg, Erwin Schrodinger, and many others. Ironically, Albert Einstein had serious theoretical issues with quantum mechanics and tried for many years to disprove or modify it.

No no in classical model of mathemetics.But in quantum logic one of these problem the factorization problem is solved by the Shor's algorithm..In fact this gave the scientist a new look for the quantum computation.

It means that it is a string holding 1440 characters. You will often find this type of declaration in a structure (also known as a user defined type). Sometimes it is needed when you have created a structure that reads a fixed length text file. \n\nFor instance, if a text file contains a record outlining a particular product, some systems require that the record be exactly X number of characters, with fields that must be padded out as necessary.\n\nIt is not a real waste of resources, you are just defining the length yourself instead of letting the program do it. You would only make such a declaration though when you know the length and it must be a certain length. Otherwise you can let the program dynamically allocate the space.\n\nCheers

Causality itself is a problem in QM. What QM does is give the probability density of these virtual particles and the adjustments to other calculations that must be made to take them into account. It also gives the probabilities of actually measuring certain particles when you do specific experiments. It does not talk about cause or effect for actual observations, though. Just probabilities.

no, minimum size and maximum energy particles can be derived from uncertanity principle, which is finite. nothing is infinite but only uncertain which cretes an illusion of infinity which is only a distribution of probability, as can be explained by quantum mechanics.

0 is the cardinal of the empty set. Thats the mathematic rigurous definition. Before that, zero was defined conceptualy, as "no object", "nothing", "none", in order to define the quantity/measure of "nothing".

What do you mean by the quistion i think it is not understood?

c. The rest are quantitative.\n\nQuantitative: 2. of, relating to, or involving the measurement of quantity or amount\n\nQualitative: 1. of, relating to, or involving quality or kind\n\nA quantitative observation involves a quantity, a number. Here are some examples: humans have 10 fingers, the speed limit is 55 miles per hour, class is 1 hour long, acceleration due to gravity is 9.8 m/s^2. These are all numbers, and usually with units to give them physical significance. These observations are quantities and the units are understood.\n\nQualitative observations are not as precise: I have many fingers, the speed limit is fast, class is long, acceleration due to gravity is large. They are descriptive adjectives, but you have to "qualify" what you mean; for example, class is long compared to (fill in blank). Otherwise, my long and your long are totally different.

We live in a universe of observable/measurable quantities. For example, length, width, height, time, mass, etc.  If different quantities cannot be expressed in terms of the other quantities, they are "orthogonal" to each other - you can think of them as being separate dimensions. For example, on an X-Y graph, the x-dimension is independent of the y-dimension because you cannot express a "y" quantity as a combination of "x" quantities. \n\nSpace has 3 dimensions (length, width, height); time is a fourth dimension that cannot be expressed in terms of the other three.\n\nAn n-dimensional space is just a space that is characterized by "n" orthogonal quantities - quantities that cannot be expressed in terms of each other. To completely define the space/universe, you only need to specify "n" values - any more than that would be superfluous because the other values would be some combination of the other orthogonal quantities.\n\nExample: if we lived in a 4-dimensional space characterized by length, width, height, and time, all you need to do is specify those 4 quantities to uniquely determine any point in that space.  If we add another quantity (such as temperature) that cannot be expressed in terms of the other 4, we now have a 5-dimensional space that requires 5 quantities to be specified.

The meaning of derived quantity is a solution to a problem.\nThe solution of the problem begins by taking known ‘quantities’ (like F=ma) and use them to build a model of the problem using information supplied by the statement of the problem. The solution is then obtained by manipulating the model employing accepted mathematical rules.\n\nThe ability to derive solution increases our ability to solve problems.\n\nI hope it was helpful.
