    Airplanes & Mobile Phones – Real World Examples Of Quadratic Equation

    There are various equations we learn and understand in elementary or high school. Some of those equations are easy, some are complex, and some are plain boring. Whether math is easy for you or difficult, one thing is true – there is no other equation to rival the majestic quadratic equation. We have entered in the era of modern technology specific calculators have been designed to solve specific problems just like Quadratic formula calculators. Now you don’t need to search the formula for Quadratic equation formula for Quadratic equation in the books, just put the values in the quadratic formula calculator and find the accurate result. I am not just talking about the equation itself but also about the practical implications of the quadratic equation. Let’s be truthful, how many times have you thought about why you are learning this stuff and where it will be useful in the practical world? The answer is almost everywhere the quadratic equation solver calculator has solved the problem.

    From mobile phones to airplanes, engineers and mathematicians are still using the quadratic equation solver calculator to solve complex problems. Amazing fact is that it is not necessary that you learn the Quadratic equation formula or to find out the formula for Quadratic equation the quadratic formula calculator automatically solves the problem by entering the values.

    To solve quadratic equations other methods are also used like graph method, factor method etc. The factor method is a famous one and there is a need to understand the factorization principles. But the factoring quadratics calculator has made this task simple and easy. By the factoring quadratics calculator, we can solve the quadratic equations in minutes.

    The story of the quadratic equation started a long time ago when the Babylonians introduced the tax system to the farmer. Understandably, the farmers were not happy about the tax so they had to calculate the land needed to be cultivated to make up for the loss in taxes. They came up with the quadratic equation to make up for their loss and estimated the land on which they had to grow crops in order to make the ends meet. As ‘necessity is the mother of invention’, the solution to a simple farming problem is still being used to solve greater problems.

    There are hundreds of uses of quadratic equations which we observe in daily life and anyone may find the quadratic function calculator to resolve the problems. What we lack is the understanding that this equation can help us estimate the results or simply understand the phenomena. Today, I have compiled a list of practical uses of quadratic equation so the next time you are solving it – you know where it can be used.

    Quadratic Chaos – When Math Meets Biology

    Don’t be surprised if any medical student finds the quadratic function calculator because the quadratic formula calculator also helps in solving biological problems. The concept of quadratic chaos is defined by the quadratic equation with the focus on biology. The population of a specific species can be estimated accurately with the help of quadratic equations. There is no pattern to the growth of species hence it is considered as chaos. In this case x is the population while ‘n’ is the years so xn+1 is considered to be the sub function of xn. If axn was bred successfully while bxn2 dies due to overcrowding – the equation will be,


    The focus of the equation is not just estimating the growth – it is more about understanding and evaluating if the prediction is accurate or hopeless.

    Mobile Phone and Complex Quadratic Equation

    The imaginary numbers were first discovered trying to find an answer to the cubic equation actually. When the imaginary numbers were used to solve the cubic equation, mathematicians were actually able to find the actual results. It was important to justify this mathematical fix otherwise we would have kept on introducing new letters ultimately running out of letters. Thus, complex numbers were introduced which are the combination of numbers and alphabets. The incorporation of cubic equations with complex numbers ultimately led to solving quadratic equations that helped in predicting electron motion. It also assisted in designing the integrated circuit that can perform complex tasks. These circuits are still being used in almost every technological invention including DVDs, computer, cars, and mobile phones. Phone signals convert the speech into high frequency radio waves and this behaviour was understood by the quadratic equation. You can say that without the simple quadratic equation ‘x2 = -1’, we would not have invented mobile phones!

    Whether we think about simple machines or the more advanced one – one thing is very clear; it wouldn’t have been possible without calculation. We owe almost all of our invention to mathematics. From growing food as per the need of the population to trying to predict natural phenomena from observing the movement of galaxies to stepping foot on moon, from calling our loved ones thousand mile away to predict the spread of infection – everything became possible for us when we dived into the realm of mathematics and its branches. One thing is very clear here – if we want to progress further, we need to reintroduce this subject to our students. Making the student understand the concept and logic behind the mathematical equation is the only way forward and we need to focus on it immediately. Maybe we will get lucky and find the next Einstein or Newton!

    Mathematical Equations That Remarkably Impacted The World

    Calculation, equation, and, math is continuously revolutionizing our world. From the time mankind wanted to calculate the field area for growing crops – there was a thirst to know and understanding the secrets of the world.

    6- Normal Distribution

    Normal probability also known as normal distribution forms a bell curve and it is signifint in statistics. It is used in social sciences, physics, and biology to define the behavior of large groups of independent processes. Normal distribution is followed in the measurement of errors, heinght, IQ score, and blood pressure.

    7- Quadratic Equation

    There are various functions that are modeled by quadratic equation including shooting a cannon, hitting golf ball, and diving. You can calculate the expected profit you are going to get if you are using the quadratic equation. It can prevent unwanted surprises and provide you with the accurate numbers and what to expect in the future. Even in the business where you are simply selling bottled water, it can help you estimate how many bottles you have to sell to generate the profit you want.

    8- Relativity

    Relativity opened the door to understanding – be it our understanding of the outer space or the speed of light. It provided us with the idea that light speed is universal but the time factor is different for the speed of people or objects. Relativity helped us understand the fate, structure, and the origin of the universe.

    9- Schrodinger’s Equation

    The behavior of atomic and subatomic particle is defined by Schrodinger’s Equation. It enhance the understanding of quantum physics hence played a huge role in the development of computing devices. Computational chemistry is the direct application of Schrödinger equation and it is currently being used in medication and engineered food.

    10- Second Law of Thermodynamics

    According to the second law of thermodynamics, heat flow from hot to cold environment due to the change in temperature. This is the concept used in the working of internal combustion engines used in airplane, ship, car, and motorcycles. The law is applicable to all engine cycles and led to the progress of modern vehicles.

    11- The Pythagorean Theorem

We were not only able to understand the concept behind natural phenomenon ut also manipulate them for the modern advancement. These were just the few examples, stay tuned to know more!

    Mathematicians Who Changed The World

    9 Mathematicians Who Changed The World

    Mathematicians are the true hero but you don’t really know about them. I can recall two or three mathematician and that’s too because they were famous physicist. Yes, I am talking about Newton and Einstein! If you ask me to list 5 mathematician, I will fail and not the normal fail where you get one name wrong – I will get all the names wrong apart from these famous too. If mathematicians are heroes then why don’t we hear about them? Well the answer to this question is pretty simple – because most of us hate math or just not bother with it! It is a sad reality especially when you look around yourself and get to know that almost everything in your room include some kind of math or any calculation. You are bored and browsing on the internet – math. You want to get the accurate dimension of the room for a new carpet – math. The circuit, the bulb, the plug, and even the spider web on you wall have some kind of mathematical pattern or logic behind it.

    We appreciate the glam of movie star but forgets to appreciate the inventors of camera. We love animated movies but forget to acknowledge the efforts of those who made is possible. This articles is an effort to appreciate our mathematician so if someone ask you to name a few with their invention – you know the answer!

    1- Albert Einstein

    He doesn’t need any introduction – he is probably the most known mathematician. Even though his contributions in the field of physics are notable and famous, his mathematical achievement are often not discussed. He contributed multiple equations to geometry and calculus, 10 of which are known as the ‘Einstein Field Equations’ published in 1915. He provide that how stress-energy can impact the curvature of space-time.

    2- Carl Gauss

    Carl Gauss was born in 1777 in Germany. Even though he was born in a poor family, he soon started to show the signs of a brilliant mind. He started elementary school at the age of 7 and his teacher was amazed when he summed the integers from 1 to 100 just by spotting that there were 50 pairs each summing 101. He was the discovered of Bode’s law, arithmetic – geometric mean, prime number theorem, binomial theorem, and law of quadratic reciprocity – all that while he was in college! He published his work title as ‘Disquisitiones Arithmeticae’ which provided the construction of a regular 17-gon nu ruler and compasses.

    His second book was ‘Theoria motus corporum coelestium in sectionibus conicis Solem ambientium’ which was published in 1809. It provided the accurate description of the motion and movement of the celestial bodies. He also discussed conic sections, differential equations, and elliptic orbitals in the first part of his book. The second part was focused on the refinement of estimating planet’s orbitals.

    3- John von Neumann

    John von Neumann was born in Budapest in early years of 20th century and you can call it our luck as her designed the architecture served as the base for the development of computer. His work was so accurate that even today the same architecture has been used with minor alterations or improvements. Even the most advanced computers of this days are cycling through a series of basic steps over and over again. This is the processing behind playing video or doing literally anything on the computer and it was first proposed by John von Neumann.

    He hold two Ph.D. one in mathematics and second in chemical engineering just because his father wanted it. He worked with Albert Einstein at Princeton University and made discoveries in quantum mechanics, computer science, set theory, game theory, and geometry.

    4- Alan Turing

    Alan Turing is known as the father of computer science and he was a British mathematician. He is well known for breaking Nazi crypto code during World War II. The code was protected by Enigma machine and breaking it gave the Allies advantage over Nazis. Some even say that it is one the main reason the Allies were able to defeat the Nazis.

    Besides doing this huge favor to the world, Turing set the basis for the development of modern computer. Till this day computer operate similarly to the ‘Turing machine’ designed by Alan Turing. Turing test is used to evaluate how well an Artificial Intelligence (AI) programs works. Any program that can pass the Turing test can have a conversation (chat) with a human fooling him to think that he is chatting with a human.

    His name is still a prestigious one in the field of computer science as Tuning Award is named after him – which is equivalent to Nobel Prize in Chemistry.

    5- Benoit Mandelbrot

    Benoit Mandelbrot discovered fractal geometry based on the complex shape built on simple formula. They are the basis of computer animation and graphics so you can think why Benoit’s name is included in this list. Without fractal much wouldn’t have been possible as they are also used to design computer chips and cellphone antenna.

    These are just the few name who made it big in the field of mathematics. There are hundreds of other mathematicians who are neglected and their work is still being used in different sector. It is important that we know our ancestors and the effort they put into making this word an advanced place!

    From Father of Math to Father of Algebra

    Mathematics is a bit dry for me. I start to solve an equation and suddenly the lizard on the wall looks interesting as compared to the equation I am supposed to solve. My lack of focus is the only thing that made me research the importance of the subject more. The more I got bored, the more I tried to understand the reason behind it. The question I asked myself was why I am solving this equation followed by who came up with this subject, and are there any mathematicians who got famous doing math? Well, as you have guessed – one question lead to another and soon I was searching for famous mathematicians. Turned out there is not one but hundreds of famous people who are mathematician. This article is a tribute to those who (unlike me) were brilliant at math. They not found the value of their ‘x’ but help millions to find it too. So let’s dive into the realms of mathematics and recognize the efforts of notable mathematicians who shaped the world as we know it today!

    1- The Pythagoreans

    Perhaps the first known mathematician and his students known as the Pythagoreans and let me make this clear – they were obsessed with number. Pythagoras presented a theorem about right angled triangles ad still considered to be the Father of Geometry for this feat. Number was not only a subject for the Pythagoreans – it was the spiritual qualities of numbers that made it the focus of effort.

    2- Euclid

    Euclid was a Greek mathematician and wrote a book titled ‘Elements’. It was the primary textbook till 19th century. He was the brain behind Euclidean Geometry which provide the basis for modern geometry. He was also the first person to formalize mathematical proofs as the method of exposition.

    3- Archimedes

    Even though the achievements of Archimedes are not limited to the field of mathematics he thought that it is the only field worth pursuing. He is known as one of the greatest mathematicians as he perfected the integration methods helping him find the surface area, volume, and center of mass of the geometrical figures. He also gave us the accurate approximation to pi and help us find the mass of object immersed in liquid.

    4- Muhammad ibn Musa al-Khwarizmi

    He is often known as the grad father of computer as he proposed the concept of algorithm which was later used in the development of first computer. We owe our understanding of algebra to Musa al- Khwarizmi. He also worked on solving quadratic equations, surveying plot of land, and dividing up inheritance.

    5- John Napier

    John Napier is known for the invention of logarithms which are still being used in different mathematical calculations. He was the first mathematician who worked towards bringing the decimal point into common usage. His logarithms helped with trigonometric calculations in astronomy and navigation.

    6- Johannes Kepler

    With German roots, Johannes Kepler was the first mathematician and astronomer who provided the idea that earth and other planets revolve around the sun in elliptical orbitals. He was also the first mathematician to provide the mathematical treatment of the close packing of equal spheres that explained the shape of honeycomb cells. He also provided a method to find the volume of solids and contributed to calculus.

    7- Rene Descartes

    The credit of using alphabets in math goes to Rene Descartes. He is known as the ‘Father of Analytical Geometry’ because of the discovery of plotting two- dimensional points on a mathematical plane. Descartes also developed four rules for deductive reasoning which are not only applied to math but to other fields of study as well.

    8- Blaise Pascal

    He is famous for Pascal’s triangle and the number used in this triangle are binomial, each number is the sum of number above. After coming out with Pascal’s triangle, he presented the probability theory. Pascal was also the first mathematical to experiment with the atmospheric pressure and came up with the statement that vacuums exit in the real world too.

    9- Isaac Newton

    Apart from his outstanding research in the field of physics, he is known as the ‘Founder of Calculus’. Newton not only gave us three laws of motions but also discovered colored spectrum along with the discovery and calculation of gravity ultimately helping us to calculate the mass of an object.

    10- Gottfried Wilhelm Leibniz

    The credit of discovering binary numeral system or the base-2 system goes to Gottfried Wilhelm Leibniz. The binary system is still used in computers and related devices ascertaining that Gottfried’s work was value in the development of compute – the most widely used device nowadays. Gottfried Leibniz discovered infinitesimal calculus which is focused on differentiation, integration, and limits of function.

    11- Thomas Bayes

    He was the first mathematician to use probability inductively along with the establishment of mathematical basis for probability inference (calculating the frequency considering the past trials). Bayes’s theorem is also a significant achievement of Bayes as it can find probability of an event in past or future based on the pattern of available data.

    12- Leonhard Euler

    Leonhard Euler worked in different fields including mathematics, physics, astronomy trigonometry, geometry, algebra, and calculus. He introduced the notation for a function f(x). He also popularized the use of the Greek letter π to denote the ratio of a circle’s circumference to its diameter.

    13- William Playfair

    Playfair was one of the most important developer of statistical graphics focusing on the idea that chart and graphs can represent data more effectively. He devised and published pie charts, statistical line graph, and the bar chart. He provided a common language to data representation.

    These were some of the notable mathematicians who changed the society as we know it. Do you know any other – tell us in the comment section so we can learn about them too!

    Asians Are Good At Math – Reality, Myth, Or Plain Racism?

    From mathematic to biology, from chemistry to physics, from theoretical to practical interventions – Asians are making their mark and it’s high time you start thinking how? Ever noticed a pattern in the results of any mathematic contest? Ever wondered why there are so many research papers being submitted by Asian countries? No, well you are not the first one to ignore this. We have been so used to celebrate the inventions of western scientist that we got used to the idea that all inventions are western.

    Most of the time we ignore the fact that we are not making as much progress in the scientific world as our Asian counterparts and this is base of our problem. What could have been a healthy competition has turned into blatant ignorance. In case the achievement of the Asian professionals are highlight – they are mostly tainted with racism. Yes – I final said the word. With the recent stark evidences, we cannot ignore the fact that we still don’t have a cure for racism in our society.

    Let me give you a recent example. The cases of Covid – 19 were first reported in Wuhan, China. It shake the basis of world economy. China was the first country to report the virus and the first to control it. Now as we are dealing with the consequences associated with the spread of Covid – 19 such as loosing job, poverty, deaths and much more – how many of us are thinking about how china was able to control it. Let’s just think about it, with the hub of virus, the largest population of the world was able to defeat a virus they don’t know much about. The answer to this question in strict control as well as intensive research. With the threat came the approach to solve it, from total shut down to multiple therapeutical approaches – China defeated the virus while we are still living under the protection of masks and calling Covid – 19 the Chinese virus.

    When we go through the scores of different countries in math contests – Asians are performing better. They are academically better and have a stronger grasp of the concept. The reason of this outstanding performance if not limited to a single factor rather it is a combination of various factors that work together to make Asians better. The first factor is old and simple hard work – Asian are known to be hard worker. With centuries of oppression and being undervalued, they had to work extra hard to make their make and thus they embrace the quote that ‘hard work pays off’. In most of the international tests, a student have to fill a detailed questionnaire and by detailed I mean around 100 questions, with persistence and hard work Asians attempt those questions while western student gets bored and leave the questions unanswered. This is a clear example of the importance of persistence, concentration, and hard work in action.

    The second factor is the parental involvement in the choice of academic career. Even though there is an ongoing debate about different parenting styles, it seems that Asians are doing something right! They have a significant role in the academic choices of their children. With the efforts of first few years when parent are teaching their children the basis of academics like alphabet and counting, they shape the mind of the child to put extra effort in the academics.

    Another reason of Asians better in math is based on simple logic – they don’t get as much vacations as we do. A Japanese school year us 243 days long, the South Korean is 220, while the average American school years is just 180 days long. With longer school years, there is increased chances of learning something new. Even if the children are not learning anything new, they are revising what they have learned previously and hence they are getting better and better every day & there are more than 50 days of getting better each year!

    Another reason for Asians being good at math is their numbers are easier. Take the example of this sequence, 4, 8, 5, 3, 9, 7, 6. Human have a 2 second span of memorizing the digits. If you speak English you are going to recall this number sequence right 50% of the time – if you are Chinese, you are going to get it right every time.
    yī = one
    èr. = two
    sān. = three
    sì = four
    wǔ = five
    liù = six
    qī = seven
    bā = eight

    As we most easily memorize whatever we can say or read within that two-second span, you can learn the digits easily. Chinese digits are brief so they fit into 2 second memory loop and help you get them right every time! These are the facts that make Asian better in math and other subject. So the next time you want hear someone throwing a racist statement away at Asian – tell them what they are doing wrong and how they can get better too. After all tolerance and information is the only way out of this dire times.
