Geometry skills are essential for a student to make progress in other branches of mathematics, such as trigonometry and topology. This makes it important for all students to have an understanding of the basic principles of trigonometry. From architecture to engineering, trigonometry is widely used in several common careers. Gaining an understanding of trigonometry opens a wide range of doors in the field of mathematics for students interested in continuing their study. What to consider when choosing an online geometry course Geometry is an essential branch of mathematics, which makes it important for any student to have a detailed, well-rounded knowledge of trigonometry that covers a variety of topics.

What are the advantages of learning geometry online? In addition, as mathematics continues to be developed, these classification schemes must change as well to account for newly created areas or newly discovered links between different areas. Classification is made more difficult by some subjects, often the most active, which straddle the boundary between different areas.

A traditional division of mathematics is into pure mathematics , mathematics studied for its intrinsic interest, and applied mathematics , mathematics which can be directly applied to real world problems. Broad divisions, such as discrete mathematics and computational mathematics , have emerged more recently. An ideal system of classification permits adding new areas into the organization of previous knowledge, and fitting surprising discoveries and unexpected interactions into the outline.

For example, the Langlands program has found unexpected connections between areas previously thought unconnected, at least Galois groups , Riemann surfaces and number theory. Arithmetic is the study of numbers and the properties of operations between them. The study of structure begins with numbers , first the familiar natural numbers and integers and their arithmetical operations, which are recorded in elementary algebra. The deeper properties of these numbers are studied in number theory.

The investigation of methods to solve equations leads to the field of abstract algebra , which, among other things, studies rings and fields , structures that generalize the properties possessed by everyday numbers. Long standing questions about compass and straightedge construction were finally settled by Galois theory. The physically important concept of vectors , generalized to vector spaces , is studied in linear algebra.

Within the world of mathematics, analysis is the branch that focuses on change: SPC is applied in order to monitor and control a process. Monitoring and controlling the process ensures that it operates at its full potential. At its full potential, the process can make as much conforming product as possible with a minimum if not an elimination of waste rework or scrap. SPC can be applied to any process where the "conforming product" product meeting specifications output can be measured. Key tools used in SPC include control charts; a focus on continuous improvement; and the design of experiments.

An example of a process where SPC is applied is manufacturing lines. Ordination Statistics is a method complementary to data clustering, and used mainly in exploratory data analysis rather than in hypothesis testing. Ordination orders objects that are characterized by values on multiple variables i. Geo-Statistics is a branch of statistics focusing on spatial or spatiotemporal datasets. Developed originally to predict probability distributions of ore grades for mining operations, it is currently applied in diverse disciplines including petroleum geology, hydrogeology, hydrology, meteorology, oceanography, geochemistry, geometallurgy, geography, forestry, environmental control, landscape ecology, soil science, and agriculture esp.

## What is Mathematics?

Geostatistics is applied in varied branches of geography, particularly those involving the spread of diseases epidemiology , the practice of commerce and military planning logistics , and the development of efficient spatial networks. Geostatistical algorithms are incorporated in many places, including geographic information systems GIS and the R statistical environment. Linear Trend Estimation is a statistical technique to aid interpretation of data. When a series of measurements of a process are treated as a time series, trend estimation can be used to make and justify statements about tendencies in the data, by relating the measurements to the times at which they occurred.

This model can then be used to describe the behaviour of the observed data. Google Trends - Google Hot Trends Visualize Patterns - Mind Maps - Comparisons Correlation and Dependence is any statistical relationship, whether causal or not, between two random variables or two sets of data. Correlation is any of a broad class of statistical relationships involving dependence, though in common usage it most often refers to the extent to which two variables have a linear relationship with each other.

Familiar examples of dependent phenomena include the correlation between the physical statures of parents and their offspring, and the correlation between the demand for a product and its price. Predicate in logic is any statistical relationship, whether causal or not, between two random variables or two sets of data.

Extrapolation is the process of estimating, beyond the original observation range, the value of a variable on the basis of its relationship with another variable. It is similar to interpolation, which produces estimates between known observations, but extrapolation is subject to greater uncertainty and a higher risk of producing meaningless results. Linear Equation is an algebraic equation in which each term is either a constant or the product of a constant and the first power of a single variable however, different Variables may occur in different terms.

A simple example of a linear equation with only one variable, x, may be written in the form: The constants may be numbers, parameters, or even non-linear functions of parameters, and the distinction between variables and parameters may depend on the problem for an example, see linear regression. Another way of saying "discrete uniform distribution" would be "a known, finite number of outcomes equally likely to happen".

Sensitivity and Specificity are statistical measures of the performance of a binary classification test, also known in statistics as classification function. Effect Size number needed to treat Second-Order Logic is an extension of first-order logic, which itself is an extension of propositional logic. Second-order logic is in turn extended by higher-order logic and type theory.

Procedural Generation is a method of creating data algorithmically as opposed to manually. In computer graphics, it is also called random generation and is commonly used to create textures and 3D models. In video games it is used to automatically create large amounts of content in a game. Advantages of procedural generation include smaller file sizes, larger amounts of content, and randomness for less predictable gameplay.

Mode in statistics is the value that appears most often in a set data. The mode of a discrete probability distribution is the value x at which its probability mass function takes its maximum value. In other words, it is the value that is most likely to be sampled. The mode of a continuous probability distribution is the value x at which its probability density function has its maximum value, so the mode is at the peak. Teach Statistics before Calculus video Analytics is the discovery, interpretation, and communication of meaningful patterns in data.

Fads and Trends is any form of collective behavior that develops within a culture, a generation or social group and which impulse is followed enthusiastically by a group of people for a finite period of time. Formulating - Validity Peter Donnelly: Statistical Survey - Scenarios Mediocrity Principle is the philosophical notion that "if an item is drawn at random from one of several sets or categories, it's likelier to come from the most numerous category than from any one of the less numerous categories".

Correspondence Mathematics is a term with several related but distinct meanings. Statistical Syllogism is a non-deductive syllogism. It argues, using inductive reasoning, from a generalization true for the most part to a particular case. Statistical Power of a binary hypothesis test is the probability that the test correctly rejects the null hypothesis H0 when the alternative hypothesis H1 is true. It can be equivalently thought of as the probability of accepting the alternative hypothesis H1 when it is true—that is, the ability of a test to detect an effect, if the effect actually exists.

Information Sources Stats is the collection and interpretation of quantitative data and the use of probability theory to estimate parameters. The quality of being probable; a probable event or the most probable event. Probability is the measure of the likelihood that an event will occur. Possibilities is the capability of existing or happening or being true. May expresses a possibility that something might happen. Relative - Hypothesis - Randomness. Guess is a message expressing an opinion based on incomplete evidence.

An estimate based on little or no information. Educated Guess is a guess based on knowledge, reasoning and experience and factors that you take into account which might affect the outcome. A well-informed guess or estimate based on experience or theoretical knowledge. Estimation is the process of finding an approximation, a value that is usable for some purpose even if input data may be incomplete, uncertain, or unstable.

Estimation Statistics is a data analysis framework that uses a combination of effect sizes, confidence intervals, precision planning and meta-analysis to plan experiments, analyze data and interpret results. Approximation is anything that is similar but not exactly equal to something else. Approximation Error in when some data is the discrepancy between an exact value and some approximation to it. An approximation error can occur because the measurement of the data is not precise due to the instruments.

Order of Approximation refers to formal or informal terms for how precise an approximation is, and to indicate progressively more refined approximations: Informally, it is simply the level of precision used to represent quantities which are not perfectly known. Approximate Number System an adult could distinguish items versus items without counting. Fold Change is a measure describing how much a quantity changes between an original and a subsequent measurement. Fold change is often used when analyzing multiple measurements of a biological system taken at different times as the change described by the ratio between the time points is easier to interpret than the difference.

Variables is an alphabetic character representing a number, called the value of the variable , which is either arbitrary or not fully specified or unknown. Probability Distribution is a mathematical description of a random phenomenon in terms of the probabilities of events. Propensity Probability is the tendency of a given type of physical situation to yield an outcome of a certain kind, or to yield a long run relative frequency of such an outcome.

Probability Density Function is a function, whose value at any given sample or point in the sample space the set of possible values taken by the random variable can be interpreted as providing a relative likelihood that the value of the random variable would equal that sample. Bayesian Probability represents a level of certainty relating to a potential outcome or idea.

This is in contrast to a frequentist probability that represents the frequency with which a particular outcome will occur over any number of trials. An event with Bayesian probability of. A frequentist will not assign probability to an idea; either it is true or false and it cannot be true 6 times out of Bayesian is relating to statistical methods based on Bayes' theorem.

Bayes' Theorem describes the probability of an event, based on prior knowledge of conditions that might be related to the event. Decisions Bayesian Inference is a method of statistical inference in which Bayes' theorem is used to update the probability for a hypothesis as more evidence or information becomes available.

Statistical Inference is the process of deducing properties of an underlying probability distribution by analysis of data. Inferential statistics can be contrasted with descriptive statistics. Descriptive statistics is solely concerned with properties of the observed data, and does not assume that the data came from a larger population. If Function Algorithms Bellman Equation is a necessary condition for optimality associated with the mathematical optimization method known as dynamic programming.

It writes the value of a decision problem at a certain point in time in terms of the payoff from some initial choices and the value of the remaining decision problem that results from those initial choices. This breaks a dynamic optimization problem into simpler subproblems, as Bellman's "Principle of Optimality" prescribes.

Reliability in statistics is the consistency that produces similar results under consistent conditions. Ratings - Truth Averages Average is around the middle of a scale. The sum of a list of numbers divided by the number of numbers in the list. In mathematics and statistics, this would be called the arithmetic mean.

In statistics , mean, median, and mode are all known as measures of central tendency. Mean is the sum of a collection of numbers divided by the number of numbers in the collection. The collection is often a set of results of an experiment, or a set of results from a survey. Middle is an area that is approximately central within some larger region. Being neither at the beginning nor at the end in a series. Equally distant from the extremes. Time between the beginning and the end of a temporal period. Percentage is a number or ratio expressed as a fraction of A percentage is a dimensionless number pure number.

Ratio is a relationship between two numbers indicating how many times the first number contains the second. The relative magnitudes of two quantities usually expressed as a quotient or the ratio of two quantities to be divided. For example, if a bowl of fruit contains eight oranges and six lemons, then the ratio of oranges to lemons is eight to six that is, 8: Similarly, the ratio of lemons to oranges is 6: The numbers in a ratio may be quantities of any kind, such as counts of persons or objects, or such as measurements of lengths, weights, time, etc.

The quantity produced by the division of two numbers. Aspect Ratio of an image describes the proportional relationship between its width and its height. It is commonly expressed as two numbers separated by a colon, as in Parameter is any characteristic that can help in defining or classifying a particular system meaning an event, project, object, situation, etc.

Parameter has more specific meanings within various disciplines, including mathematics, computing and computer programming, engineering, statistics, logic and linguistics. Within and across these fields, careful distinction must be maintained of the different usages of the term parameter and of other terms often associated with it, such as argument, property, axiom, variable, function, attribute, etc. Luck - Comparisons Parallel Individuation System is a non-symbolic cognitive system that supports the representation of numerical values from zero to three in infants or four in adults and non-human animals.

It is one of the two cognitive systems responsible for the representation of number, the other one being the approximate number system. Unlike the approximate number system, which is not precise and provides only an estimation of the number, the parallel individuation system is an exact system and encodes the exact numerical identity of the individual items. The parallel individuation system has been attested in human adults, non-human animals, such as fish and human infants, although performance of infants is dependent on their age and task Intraparietal Sulcus is processing symbolic numerical information, visuospatial working memory and interpreting the intent of others.

Operationally Impossible is considered to be 1 in 10 to the 70th Power Power of 10 is any of the integer powers of the number ten; in other words, ten multiplied by itself a certain number of times when the power is a positive integer. By definition, the number one is a power the zeroth power of ten.

Size Margin of Error is a statistic expressing the amount of random sampling error in a survey's results. It asserts a likelihood not a certainty that the result from a sample is close to the number one would get if the whole population had been queried. The larger the margin of error, the less confidence one should have that the poll's reported results are close to the true figures; that is, the figures for the whole population. Margin of error applies whenever a population is incompletely sampled.

Precision is a description of random errors , a measure of statistical variability. Accuracy has two definitions: More commonly, it is a description of systematic errors, a measure of statistical bias ; as these cause a difference between a result and a " true " value, ISO calls this trueness. Alternatively, ISO defines accuracy as describing a combination of both types of observational error above random and systematic , so high accuracy requires both high precision and high trueness. In simplest terms, given a set of data points from a series of measurements , the set can be said to be precise if the values are close to the average value of the quantity being measured, while the set can be said to be accurate if the values are close to the true value of the quantity being measured.

The two concepts are independent of each other, so a particular set of data can be said to be either accurate, or precise, or both, or neither. Precision in statistics is when the precision is the reciprocal of the variance, and the precision matrix , also known as concentration matrix, is the matrix inverse of the covariance matrix. Some particular statistical models define the term precision differently. Markov Chain is a process satisfies the Markov property if one can make predictions for the future of the process based solely on its present state just as well as one could knowing the process's full history.

Markov Property refers to the memoryless property of a stochastic process. Memorylessness is a property of certain probability distributions: Stochastic Process is a probability model used to describe phenomena that evolve over time or space. More specifically, in probability theory, a stochastic process is a time sequence representing the evolution of some system represented by a variable whose change is subject to a random variation.

Time Management - Virtual Reality Relative Change and Difference are used to compare two quantities while taking into account the "sizes" of the things being compared. The comparison is expressed as a ratio and is a unitless number. By multiplying these ratios by they can be expressed as percentages so the terms percentage change, percent age difference, or relative percentage difference are also commonly used. The distinction between "change" and "difference" depends on whether or not one of the quantities being compared is considered a standard or reference or starting value.

When this occurs, the term relative change with respect to the reference value is used and otherwise the term relative difference is preferred. Relative difference is often used as a quantitative indicator of quality assurance and quality control for repeated measurements where the outcomes are expected to be the same.

A special case of percent change relative change expressed as a percentage called percent error occurs in measuring situations where the reference value is the accepted or actual value perhaps theoretically determined and the value being compared to it is experimentally determined by measurement.

Observation Errors - Error's Analytics is the discovery, interpretation, and communication of meaningful patterns in data. Especially valuable in areas rich with recorded information, analytics relies on the simultaneous application of statistics, computer programming and operations research to quantify performance. Google Analytics - Watson Analytics Piwik Analytics Software Web Analytics Software List wiki Saplumira Research science - Mind Maps Calibrate Calibration is the process of finding a relationship between two quantities that are unknown when the measurable quantities are not given a particular value for the amount considered or found a standard for the quantity.

When one of quantity is known, which is made or set with one device, another measurement is made as similar way as possible with the first device using a second device. The measurable quantities may differ in two devices which are equivalent. The device with the known or assigned correctness is called the standard. The second device is the unit under test, test instrument , or any of several other names for the device being calibrated. There may also be bias in the research or even mistakes made, so always check for accuracy before making a decision on what action to take or when determining how to use data.

You should also use calculations that students will need to preform in order to solve a problem that they will most likely face in the immediate future or far future. The main reason why you use real life situations or scenarios when learning math is the associations. When you associate knowledge with other knowledge that is used often, you remember it more often, so the knowledge stays with you longer.

That is why you can easily remember things when you associate them with other things, which is one of the key techniques in having a good memory. When you have nothing to associate something with, you forget it, to a point where you will not even remember why you even learned this knowledge in the first place. This is what education is today, fragmented and incoherent. Kids have to learn how to use math in their everyday life, if they don't, they will eventually forget it and never use it effectively or efficiently.

Knowing how to count doesn't matter if you don't count the things that matter. Real life Preparation has to be the goal in all educational courses. Example Choice when students see a connection between physics and the real world, they learn easier because the subject is more interesting and relevant to their daily life. Public Sphere Pedagogy represents an approach to educational engagement that connects classroom activities with real world civic engagement.

The focus of PSP programs is to connect class assignments, content, and readings with contemporary public issues. Students are then asked to participate with members of the community in various forms of public sphere discourse and democratic participation such as town hall meetings and public debate events. Through these events, students are challenged to practice civic engagement and civil discourse. Demonstration Teaching involves showing by reason or proof, explaining or making clear by use of examples or experiments.

Demonstration is a show or display and the act of presenting something to sight or view. Proof by a process of argument or a series of proposition proving an asserted conclusion. Don't force students to figure something out if they can't use that knowledge in real life. Because they will just forget it, which is why school testing is a failure and a disservice. It's been well documented that students forget almost everything they saw on a test, so what's the point? If you want to use a math formula or use a problem solving technique using numbers, then give a clear example of how those numbers can be used to symbolize real things in their life, things that they should know because they are part of a valuable skill set.

The action learning process includes: Authentic Learning is an instructional approach that allows students to explore, discuss, and meaningfully construct concepts and relationships in contexts that involve real-world problems and projects that are relevant to the learner. The basic idea is that students are more likely to be interested in what they are learning, more motivated to learn new concepts and skills, and better prepared to succeed in college, careers, and adulthood if what they are learning mirrors real-life contexts, equips them with practical and useful skills , and addresses topics that are relevant and applicable to their lives outside of school.

An example is a factory that increases output by learning how to use equipment better without adding workers or investing significant amounts of capital. Learning refers to understanding through thinking ahead and solving backward, one of the main problem solving strategies. Learning Methods Count the things that Matter Read to Learn Real Life Examples If someone is going to show you how to use a hammer, then they should also show you how to build a house using a hammer.

Learning how to use a hammer is not interesting or fun, but when you learn what a hammer can do, then it becomes an incredible tool. Like math, learning how to do math is boring, but once you learn what math can do, then you can use math to build your own house, or maybe even use math to build a spacecraft and fly to the moon. When learning does not have that bigger goal in mind, then learning becomes pointless and boring, and then people don't learn enough or keep progressing. Where ever students are, use that students needs in the present moment as a teaching format.

What ever a person is struggling with, use that particular struggle to teach them how to over come their struggle using reading, writing, math, science, biology, or any other useful subject or skill. This way you increase their understanding of important subjects and also help solve their problems that they are experiencing now, or may experience in the future. Help them with life, and help prepare them for the future. As you are walking towards a goal, teach them along the way, and most important, show them the power of learning, and make every student understand that they need to be able to learn on their own , because that is the most important skill that they will ever have in life.

And if they never learn to learn, or never learn how important it is to be able to learn on their own, then they will struggle with life, and they will most likely never acquire true success or true happiness. A lesson should have a beginning, a middle and an end. It should explain the procedure used, if one was used.

### Knowledge Base

It should explain why particular problem solving skills where used? It should explain the things to be aware of and why? It should explain the learning path that was chosen and that it was not a blind mindless reaction.

As history has taught us, just because something was done in a particular way for a long period of time, it does not mean that it can't be improved. This video is one example, but it needs to be even more reality based. Real World Math Examples This video did not go far enough to teach all the variables.

And you could have showed more examples of how to estimate the altitude , like holding the drone over a yard stick, if the drone can see the entire yardstick at 2 feet off the ground, then you could estimate the altitude needed in order to see yards if the drone was in the middle straight up from the 50 yard line. In the video they said the altitude needed was So the lens of the camera definitely influences field of view like with a wide angle camera lens.

It would been even more accurate if you added an Ariel photographers expertise to explain important factors of Ariel photography, and also teach safe Drone Operation. Education improves decision-making ability and economic rationality, study finds. Using a randomized controlled trial of education support and laboratory experiments that mimic real-life examples , we established causal evidence that an education intervention increases not only educational outcomes but also economic rationality in terms of measuring how consistently people make decisions to seek their economic goals.

Knowing the math behind a problem , or knowing the math behind a solution or goal, helps to clarify its true significance and also helps explain what decisions and choices are available. This is when math reveals its true power. Math is not the only factor when solving a problem, or the only factor that clarifies true meaning. There are also other factors that could help solve a problem, or reach an understanding.

Some people can understand math a lot sooner than other people can. Some people can understand math at the age of 12 and some people at the age of The only difference is the options that a person will have at that particular time in their life. Once you reach a certain level of knowledge, you have more possibilities to choose from and more options concerning a particular educational direction, like being a doctor, a lawyer, a farmer, a leader, or a representative of the people.

The 20 year old will still have the same potential, but only at a later time, but only if they keep learning. The Fields Medal is sometimes viewed as the highest honor a mathematician can receive. The Fields Medal differs from the Abel in view of the age restriction mentioned above. Nobel Prize is a set of annual international awards bestowed in a number of categories by Swedish and Norwegian institutions in recognition of academic, cultural, or scientific advances. Math Trick Choose a number 1 through Lets say that you choose the number 8.

Now double that number, which would now be Now add 6 to 16, which is now Now dived 22 by 2, which is now Now minus the original number, which is 8 from Your answer is 3. The three steps are: In the concrete step, students engage in hands-on learning experiences using concrete objects such as chips, dice, or paper clips. This is followed by drawing pictorial representations of mathematical concepts. Students then solve mathematical problems in an abstract way by using numbers and symbols. Metric System is a decimal system of weights and measures based on the meter and the kilogram and the second, multipliers that have positive powers of ten.

International System of Units or SI is the modern form of the metric system, and is the most widely used system of measurement. It comprises a coherent system of units of measurement built on seven base units. The system also establishes a set of twenty prefixes to the unit names and unit symbols that may be used when specifying multiples and fractions of the units.

Cubit is an ancient unit based on the forearm length from the middle finger tip to the elbow bottom. Roman Numerals is a system represented by combinations of letters from the Latin alphabet. Roman numerals, as used today, are based on seven symbols: A mathematical treatise consisting of 13 books attributed to the ancient Greek mathematician Euclid in Alexandria, Ptolemaic Egypt c. Some of the things that Math can Do Calculations or Computations is problem solving that involves numbers or quantities. Planning something carefully and intentionally.

The procedure of calculating; determining something by mathematical or logical methods. Calculations - Time Management. Procedure is a particular course of action intended to achieve a result. A process or series of acts especially of a practical or mechanical nature involved in a particular form of work.

Process is to perform mathematical and logical operations on data according to programmed instructions in order to obtain the required information. A particular course of action intended to achieve a result. Shape, form, or improve a material. Subject to a process or treatment, with the aim of readying for some purpose, improving, or remedying a condition.

Operations is a process or series of acts especially of a practical or mechanical nature involved in a particular form of work. Operation is a calculation from zero or more input values called operands to an output value. Function is a mathematical relation such that each element of a given set the domain of the function is associated with an element of another set the range of the function. The actions and activities assigned to or required or expected of a person or group. A relation such that one thing is dependent on another.

What something is used for. Perform as expected when applied. Function in mathematics wiki. Measure is the assignment of a number or values to a characteristic of an object or event, which can be compared with other objects or events. To determine the measurements of something or somebody, take measurements of. Express as a number or measure or quantity. Evaluate or estimate the nature, quality, ability, extent, or significance of. Any maneuver made as part of progress toward a goal.

How much there is or how many there are of something that you can quantify. The act or process of assigning numbers to phenomena according to a rule. A basis for comparison ; a reference point against which other things can be Evaluated. Measuring instrument having a sequence of marks at regular intervals; used as a reference in making measurements.

A container of some standard capacity that is used to obtain fixed amounts of a substance. Measuring Instrument is a device for measuring a physical quantity. In the physical sciences, quality assurance , and engineering, measurement is the activity of obtaining and comparing physical quantities of real-world objects and events. Established standard objects and events are used as units, and the process of measurement gives a number relating the item under study and the referenced unit of measurement.

Measuring instruments , and formal test methods which define the instrument's use, are the means by which these relations of numbers are obtained. All measuring instruments are subject to varying degrees of instrument error and measurement uncertainty. System of Measurement is a collection of units of measurement and rules relating them to each other. Systems of measurement have historically been important, regulated and defined for the purposes of science and commerce. Systems of measurement in modern use include the metric system , the imperial system , and United States customary units , which uses the inch , foot , yard , and mile , which are the only four customary length measurements in everyday use.

Units of Measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same quantity. Any other value of that quantity can be expressed as a simple multiple of the unit of measurement. History of Measurement wiki. CGS is a system of measurement based on centimeters and grams and seconds. Level of Measurement is a classification that describes the nature of information within the numbers assigned to variables. Classification with four levels, or scales, of measurement: Metrology is the science of measurement and includes all theoretical and practical aspects of measurement.

The ruler is a straightedge which may also contain calibrated lines to measure distance. Tools for Measuring engineering Slide Rule is a mechanical analog computer. The slide rule is used primarily for multiplication and division, and also for functions such as exponents, roots, logarithms and trigonometry, but is not normally used for addition or subtraction.

## Glossary of Mathematical Terms - The Story of Mathematics

Though similar in name and appearance to a standard ruler, the slide rule is not ordinarily used for measuring length or drawing straight lines. How to Use a Slide Rule: Logarithm is the inverse operation a function that "reverses" another function to exponentiation. Measuring gives us the ability to predict the future. So that means we can literally control our own destiny.

We can even measure ourselves, to measure the measurer. Learn to measure , measure as much as you can, and measure the things that are the most important. If you can't measure something yourself, then find someone who can measure it for you. Measuring encompasses many different skills, but the skills to accurately decipher your measurements will always be the most important.

Why, when, where, who, how, value , priority? Quantification in science is the act of counting and measuring that maps human sense observations and experiences into quantities. Quantification in this sense is fundamental to the scientific method. Quantifier in logic is a construct that specifies the quantity of specimens in the domain of discourse that satisfy an open formula. Quantities is how much there is or how many there are of something that you can quantify.

The concept that something has a magnitude and can be represented in mathematical expressions by a constant or a variable. Quantity is a property that can exist as a magnitude or multitude. Quantities can be compared in terms of "more", "less", or "equal", or by assigning a numerical value in terms of a unit of measurement.

Quantity is among the basic classes of things along with quality, substance, change, and relation. Some quantities are such by their inner nature as number , while others are functioning as states properties, dimensions, attributes of things such as heavy and light, long and short, broad and narrow, small and great, or much and little. A small quantity is sometimes referred to as a quantulum. Physical Quantity is a physical property of a phenomenon, body, or substance, that can be quantified by measurement.

A physical quantity can be expressed as the combination of a magnitude expressed by a number — usually a real number — and a unit: Volume is the amount of 3-dimensional space occupied by an object. The property of something that is great in magnitude. Volume is the quantity of three-dimensional space enclosed by a closed surface, for example, the space that a substance solid, liquid, gas , or plasma or shape occupies or contains. Volume is often quantified numerically using the SI derived unit, the cubic metre. The volume of a container is generally understood to be the capacity of the container, i.

Capacity is the capability to perform or produce. The maximum production possible. The power to learn or retain knowledge; in law, the ability to understand the facts and significance of your behavior. Load is a quantity that can be processed or transported at one time.

The power output of a generator or power plant.
