Math Subjects Taught For Students At School

We are trained to fix statistical issues in a variety of different ways. The pad and document methods are the most popular way we show kids to fix applied mathematics issues. Learners are also requested to understand how to use psychological statistical to quickly fix mathematical issues without the use of document and pad. Finally, students are requested to implement the commercial calculator and Solceller to finish the majority of their calculations issues. The commercial calculator is the method that has triggered a lot of conversation. This question is always asked: At what age should we use this tool to show our kids to fix mathematical problems?

Some people believe that the Solceller enables the kids to focus more on the mathematical knowing and ideas instead of a bit of your efforts on training calculations abilities. This machine can help kids finish complicated statistical functions. The instructor can take a longer interval training mathematical principles, thus more arithmetic can be trained each category interval. Instructors are always under pressure to show a certain variety of principles each category interval, and if students have to invest lots of your efforts finishing easy calculations, how can they show new concepts?

Furthermore, some students become disappointed because they don’t have enough chance to finish their mathematical issues. This is in part due to the fact that they don’t have a good knowing of statistical calculations abilities. This may cause students to be troublesome or less focused in college. Some of these students have been permitted to implement the Solceller calculator in college because the instructor doesn’t want to invest longer training to students on the basic abilities that they skipped in their earlier attribute. So, the calculator is used to allow the instructor to continue training the class. Research has also said that kids can use the calculator at any quality stage, provided that they are utilized properly. The analysis says that the calculator should be used as a supplement to learning and not as an alternative. In addition, the instructor must be knowledgeable as to how to utilize the calculator in the educational setting training. Research also declares that most teachers are not trained in the use or neglect of hand calculators in educational setting training.

This information is important, but let us not ignore, if students start using a calculator to fix easy mathematical calculations at a young age, they will becoming reliant on them in the future? When will they understand their time tables? In Asia, where kid’s statistical ratings are very great, kids are prohibited to use hand calculators until they reach the junior great university stage. Even then, students use the calculator occasionally. I suppose they use them at the secondary university stage in the higher-level sessions, like calculus. Students who become reliant upon using hand calculators are losing their psychological calculations abilities. This can hurt them in the lengthy run when more psychological calculations may be needed. The old saying, “if you don’t use it, you lose it”, is true. Learners who quit utilizing their mind to do mathematical calculations will ignore easy statistical projects, thus mathematics will become tougher for them.

The Fermi Paradox

The detection of life somewhere in the Universe other than the Earth would probably be the greatest discovery in history.  When pondering this thought a physics/maths teacher called Enrico Fermi wondered why considering the age and sheer size of the Universe that no other species had got in contact with us so far.  Think of it there are billions of stars, billions of planets which have all existed for billions of years – you would think that SETI would have picked up more than just white noise.

At the heart of this idea is a paradox – the Fermi Paradox.  It was in 1961 that Frank Drake perhaps moved towards an answer to this paradox when he developed an equation for the probability of a contactable alien society living somewhere else in the Milky Way.  The Drake equation tells us that there is a chance but it’s still quite uncertain.

Here’s the basis of the Drake Equation

N=N*x FpxNexFixFjxFcxFl

Where

N is the number of civilizations in the Milky Way detectable by electromagnetic emissions

N* is the number of stars in the Galaxy

Fp is the fraction of stars which have planetary systems

Ne is the number of planets per solar system with an environment suitable for life

Fi is the fraction of suitable planets which have actually shown some life

Fl is the fraction of life bearing planets which have spawned intelligent life

Fc is the fraction of civilisations capable of communicating their existence into space

Fl is the fraction of the civilisations lifetime that detectable signals have been released (e.g for Earth it’s pretty small!)

Obviously some of these variables are quite difficult to calculate but all our research suggests that we should have been contacted somehow by something.  So Fermis Paradox still is true.  If you’re interested more about this subject it’s covered by two maths series on British Television one on BBC and the other Channel 4.  If you have trouble connecting with UK TV because of your location – this website shows you how to watch the BBC  abroad.  It’s a simple technique involved in just routing through a UK located proxy server which allows video streaming.

Useful Formulas in Working Out IT Costs

If you’re in charge of a network you can spend an infinite amount of money and resources in defending that network.  This is simply because there are such a huge amount of threats and numerous ways of defending them.  However clearly not many organisations are going to be able to write a blank cheque to defend their network and data however valuable it may be to them.  There is a whole branch of specialised calculations that have been developed to assess these risks in order to try and defend against them.

An interesting calculation is the Annualised Loss Expectancy (ALE) which occurs when a threat pairing can be expected to happen more than once in a specified year.  ALE is not just used as an assessment in network defense it is equally valid in models which involve shoplifting, bad debt risks and hundreds of different areas.  The decision that any firm must make is “How many ALE events can we withstand as a company?”.   For instance say you own a web based mail order business – downtime on your website has direct cost implications.  If we consider DoS attacks (a favorite against commercial web sites) – imagine each one takes down your site for an average of two hours and you can expect this to happen three times a month?  How much should you spend to defend aganst this.

Protecting against DoS is a very good example simply because there is no real limit on  the amount you can spend.  Here’s the formula for calculating ALE –

SLE x Annulized Rate Occurence = Annual Loss Expectancy

It’s quite simple when you look through it, simply the the SLE multiplied by the number of expected events.  The total and cost obviously depend largely on  the calculation of SLE.  How about applying it to a different scenario – perhaps the amount of wasted time by employees surfing the web in a given day.  Lets imagine 500 employees and they spend 25% of their time messing around on the web on sites like Facebook and Twitter.

$50/hr x 125 = $6250

To calculate ALE from this figure we need to determine that they waste this money every single week except when they’re on holiday (lets give them only two weeks off the slackers!)

$6250 x $50 = $312,500

Which is a serious amount of money wasted.  You could spend a small proportion of this amount in tightening up your internet gateway, make sure you put in restrictions and web filtering to block against the basic ninja surfing techniques and basically you’d be clawing back money lost pretty quickly.  

Maths Learning resources

There’s one thing for certain, if you have any inclination or need to improve your maths then the internet has the answers.  The web is literally stuffed full of maths courses, tutorials, explanations and puzzles.  Whatever your level there is no doubt that something will be available for you somewhere.

For this article I’d just like to briefly explain the maths resources that are available on the BBC web site.  The BBC is truly one of the most outstanding sites on the internet, it’s my favourite without doubt simply because of the breadth of information available.  The vast majority of it is is free, however due to certain copyright problems you might have trouble accessing the BBC Iplayer site if you’re outside the UK.  If you do have this problem – check this post out which shows you how to circumvent the BBC geotargeting efforts – http://www.anonymous-proxies.org/2009/02/using-iplayer-abroad-viewing-bbc-via.html.

So what is exactly on the BBC web site?

Well perhaps the most impressive information is on the basic level which is stored on something called ’Bitesize’.  This is primarily a schools educational resources teaching basic maths like addition, subtraction  and multiplication etc.  There’s a wonderful show on the World Service including one called Figure it Out. If you’re an adult who needs to learn maths for a very specific employment related purpose then check out Learn Direct – which has 42 free online maths courses specifically to improve basic numeracy.

For everyday finances, there’s the BBC Raw Website which deals with everyday maths problems like evaluating loans, mortgages and stuff like that.

 

Individuals Life Involving Mathematical Aspects

Math is use in our everyday life constantly. Mathematical computation is something which we cannot live without. In the real life mathematics has great benefits for us like we can calculate easily and if we don’t know about maths we can not calculate easily. It plays a vital role in everyone’s daily life since the life of people dealt much on counting matters. Just Think about how can a certain person would possibly count the days, months, and years. For budgeting our expenses and organizing our financial assets daily is connected with math. But many can’t seem to realise that even in our daily business math does affect us more that just counting the coins at the grocery shop or calculating how big a carpet you want. Advanced mathematics are used in advanced softare tools such as business intelligence and analytics tools like the ones found at Analytics Tools which can help improve an entire business just by calculating various factores.

Certainly it is very important for life since it helps us to quantify all the visible and invisible things with which we are dealing in daily life. There are many uses of mathematics in real life most likely in jobs like accounting, banking , store manager or just working at a simple fast food store. It naturally helps us to have an objective views of different things around us which ewe dealt with. It helps our engineers, construction workers and even the carpenters making calculations about the things which are not physically developed like for buildings before construction or using analytics tools to see which part of a business is healthy enough to expand.

It helps us to have an idea that how much earning or spending has been done and would it be beneficial to do a certain activity or not. In today’s world mathematics is being applied everywhere like in the economy of a country, construction of buildings, marking and evaluation of persons. It would be appropriate to say that mathematics has helped a lot in achieving the fast speed life with all its comforts and delights. Maths is all around us. It is present in different forms; it is undeniably important that we take note of it like we do with modern business intelligence tools such as Business Intelligence Tools which can actually aid many large companies increase their economy just by using advanced math in order to show the proper data.

Things are measured or accurate due to maths. Mathematics has a prominent role to play in our daily life. We even didn’t realize that maths is involves in every sort of activities. Whenever we pick up the phone, manage the money, travel to some other place, unintentionally in all these things maths is involved. This is how mathematical factors affects the daily life of a certain human. We cannot deny that life will run smoothly without the presence of mathematics. Math is within humans life.

It is said that mathematics is said to be the mother of all sciences. It is absolutely mean that sciences that are evolved have a sound foundation in mathematics if we go further in debate it would be justified to say that the blessings of all these modern sciences and technologies are only possible with mathematics. There are many uses of mathematics in real life most likely in jobs like accounting, banking , store manager or just working at a simple fast food store. It is not all about formulas and calculations. Its a subject that has life in it. Mathematics is simple, interesting and delightful and also useful for you as a private person needing to find the size of your house, or the modern business owner wanting facts about his company using analytic tools or business intelligence. Solving life problems is certainly related to math. In fact mathematics is involved directly or indirectly wherever we go and every thing that we may use.

The Latent Variable

In 1904 Charles Spearman published a research paper that set the foundation of latent variable modelling. Introducing the concept of general intelligence or ‘g’ Spearman statistical contribution showed how to measure a latent variable which could not be observed.

Latent variables refer to a small number of hidden variables that impact and are the cause of variables that can be observed and recorded. Human behaviour is extremely complex and governed by more than one latent variable. For example, job performance can be linked to g, but a latent variable of social avoidance can lead to social anxiety.

Latent variable models rescale the variables enabling them to be interpreted in regards to correlations between what is observed and what can’t be observed. However care needs to be taken when interpreting the relations between individual observed variables and what psychological meaning can be attributed to those factors.

In statistical analysis of Latent Variables, there are a number of methods for estimating the (alpha) values, the most suitable is called maximum likelihood, but other methods have their purposes and produce similar results. However, most computer methods of statistical analysis, such as SPSS load the output of values in tables or loading matrix.

The main reasons that people conduct latent variable analysis is firstly to understand the relationship between different observed variable and the other is in regards to statistical procedures to calculate factor scores, for example using the regression method.

In organisational life cognitive ability is measured using pen and paper tests (or online equivalents) because of the importance of g in many areas of everyday functioning. For example, the ability to achieve academically, the likelihood of divorce and of involvement in criminal behaviour have all been linked to cognitive ability. In many circles it is believed that in measuring future job performance cognitive ability is the best predictor of job performance. However, g measures the maximum potential that a person may have and there is no agreed definition for intelligence.

However, in recent years, research has disputed this fact, and there has been an increase in the use of aptitude testing which seek out latent variables which could point to as yet unrecognised or untapped potential within an individual. In additional personality tests, which measure typical behaviour offer a glimpse in to behavioural traits, which have more relevance in regards to cultural fit, motivation, attitude and the ability to adapt and flex which are essential in todays market place.

Many Personality and Aptitude test specifically measure latent variables that are necessary in order for someone to be able to perform a job well. Research and statistical evidence which you can read online and on UK TV with a VPN  has produced a number of tests that are able to recognise a latent variable for being able to learn languages proficiently; even in people who have had no language training. Other tests measure whether someone is a super responder, that is they have the ability to recognise faces, a skill which was used to great affect in identifying the often hoodie wearing perpetrators of the London riots in 2011.

Very little is understood about what latent aptitude variables are necessary to perform specific job tasks within the organisation. Organisations build talent management programmes on ‘leadership’ talent often employing personality and cognitive ability tests to identify high potential individuals in their organisation. But these programmes very often miss 80% – 90% of the employee population.

Does this mean that these people lack talent? The challenge, and future research on talent needs to explore latent variables in order to understand what aptitudes led to favourable job performance. The need is for organisations to find an efficient way to identify the latent talent that exists in their entire employee population rather than restricting ‘talent’ to those whose talent can be measured by the current raft of tests and statistical validity today.

Is Math too Abstract?

One of the things that puts young people off studying maths is that it is too abstract. Maths is hard to grasp for many because it appears too theoretical. Math appears to inhabit a parallel universe to the everyday world, and this puts many people off.

For others this is the attraction of mathematics – it is a world that has its own immutable laws and its own internally coherent logic. Math seems neater and more precise than the real world.

However, this characterization as math being distinct, separate and autonomous from nature is a very much mistaken one. Math obviously originated as a means of dealing with amounts. This is the common way to present math problems to kids – you have 10 apples and 5 people  – how many apples can each person eat? From this example it can be seen that math allows us to symbolize amounts of actual things in numbers and make calculations. The next step is to substitute unknown amounts for letters (algebra) and to use math equations to work out the unknown quantity.

Math is fundamental to the world we live in. Math is the foundation behind scientific equations. These equations allow engineers to turn science into technology that can benefit our lives. The same is true for medicine. We wouldn’t have any of the life saving drugs we do have without maths and chemistry.

From science to sport there is no area that mathematics doesn’t touch.  Look for instance at a computer game like FiFa 18, they don’t just copy  the movements from match of the day online – maths is at the heart of all the movement algorithms.

Man’s greatest achievement has been to make models of the world and through understanding these models to manipulate reality. These models whether computer simulations, scientific theories or chemical equations are based on maths and cannot exist without math. It is not wrong to describe math as abstract, but it is very wrong to consider math as separate and irrelevant to reality. Indeed for anyone living in a city what they see out of their window in the product of math and applied math.

Math and Wine

I don’t think many of us draw the connection between what amounts to our favorite alcohol and math.  It’s there if you take the time to look though.

To start, think about your favorite bottle of wine.  Or more simply, think about any of the 90 point wine clubs which exist only to find those exact bottles.

The real question is how winemakers are able to craft wine which is of that high quality. There is, without a doubt more science involved than you might think.  Most of us believe that a winemaker walks through a vineyard throughout October and tastes grapes.  When the grapes taste just right they are picked and then left alone to ferment and create the wine we drink on a nightly basis.

While that certainly happens in some places-at most wineries these days winemaking is more science than art.  Wineries employ full time chemists (they call them enologists, but they’re nothing more than chemists) who test the sugar levels of grapes before the winemaker becomes involved at all.

I think we all know that math is incredibly important, but did you know how much math really went into that bottle of wine you’re enjoying with dinner?

Do Your Maths, Make A Decision And Save A Fortune

When was the last time you sat down to really look at your monthly expenditure? More specifically when was the last time you worked out the math on your non essential monthly expenditure? This starts to get very interesting for those of us that happen to be smokers. If you smoke a pack a day, going off an average price of $7 per pack, you will be spending on average $213 per month.

This is a fair amount but seeing this figure doesn’t always have an impact for many people. Well, how about doing the math on that figure over a 5 year period? $12,780. Now we have your attention! If you have been a long time smoker just think what you could do with this amount of money or even just half of it. A luxury family holiday maybe? Down-payment on a house? There is a lot you could do!

This might seem to over simply the fact that there is still the small issue of giving up the smokes. There are many options but one of the latest alternatives to tobacco that has given many people positive results is the e cig. Thousands of people have made the switch and a large percentage of them have managed to kick their nicotine habit altogether. Look out for an honest e cigarette review and you won’t go far wrong, it can be a little daunting at first due to the large number of brands out there but stick with it. Their are different price ranges and an initial outlay for the equipment but once you have this all you need to do is buy the cartridges that contain the nicotine.

Take a step back, think about the money you could save and what you could invest that money in.
