INTRODUCTION TO MY BLOG

Hello everyone and welcome to "Measurement & else"!

I am excited to establish this blog, because it is the second blog that I write about mathematics and I enjoyed writing the last one. This blog will be focused on : measurement. Sometimes, mathematics can be boring, but it will not my purpose. Mesurement has got interesting facts, curiosities that some of us do not know and the most important: we can measure almost everything that sorround us and thanks to that, we can interpret the reality in order to deal with issues that we can find in our society and environment.

The main objective of this blog is to present the measurement from a interesting point of view and also, from a didactic one. There will be several analysis of articles and resources than can be used in Primary Education classes. The mathematics and measurement are fun and it will be reflected in this blog so I invite you to share your opinion in it!

I hope you enjoy reading my entries!

THE EFFECT OF MEASUREMENT IN MUSIC

Does it exist any connection between mathematics and music?, and if so, how does it affect us? As surreal as it turns out, the relationship exists. To understand it, we have to go back to ancient Greece, specifically Pythagoras. He was who discovered the importance of numbers in music and the relationship between this discipline and mathematics. The word mathematics comes from the Greek word μάθημα, which means "knowledge". Pythagoras and his followers divided this science into four areas: arithmetic, geometry, astronomy and MUSIC . For this reason, we could affirm that the Pythagorean philosophers were the ones who laid the foundations of our current music. Nowadays, mathematics has to do even more with acoustics than with composition and the use of mathematics in composition is historically limited to the simplest operations of measuring and counting. As a result of that, we could affirm that we feel emotions and feelings through songs because of...

DRAWING CONCLUSIONS

As it was explained in the previous entry, "CURIOUS NBA STATISTICS", statistics is "a branch of mathematics dealing with the collection, analysis, interpretation, and presentation of masses of numerical data". The application of statistical procedures dates back to the year 3050 before Christ , when a register of population and wealth was carried out in Egypt in order to prepare the construction of the pyramids. Later, Egyptians, Greeks and Romans also carried out some censuses with tributary, social and military purposes, and much later, in the sixteenth century, statistical inventories were published in Germany, Italy and France. Although initially the statistics arises from the elaboration of censuses, its application is currently extended to numerous fields, such as agriculture, biology, politics, psychology, education and so on. However, there are many people who for lack of critical sense of a statistical nature are very easily impressed by surpris...

COUNTRIES´ SIZE

We have spent our entire lives looking at the wrong map: the Mercator projection ,which is the most frequently one used on the world maps. It enormously distorts the size of the countries or territories closest to the poles (essentially, those that are in the northern hemisphere) and, in comparison with it, it minimizes those that are closed to Ecuador, especially, South America and Africa. That explains why we have been mistakenly thinking that Greenland is similar in size to Africa, when in fact it is fifteen times smaller! [ Mercator projection of the world ] Moreover, a new projection to measure the countries was used at the beginning of the eighties in order to solve Mercator projection´s problematic: Gall–Peters projection . However, it was a terrible idea because it incurred a series of topographical errors. [ The Gall–Peters projection of the world map ] This distorting effect is inevitable due to the Earth is a sphere and not a...
