WHY DOES USA USE A DIFFERENT METRIC SYSTEM?

How many times have we listened to words such as "inches" or "miles", which we are not accustomed to use. Where are these measurement units used? and, why are there different measurement systems? But lets go one step at a time.

The United States is one of the few countries in the world that does not use the metric system, because it uses the so-called Anglo-Saxon system of units where the kilogram, liter and kilometer are replaced by other measures that the less we understand. There are different ways of measuring weight, volume, distance and temperature, among other things, and they tend to be grouped within different systems. In almost all the world we use the metric system, but the United States is one of the few countries that does not use it. And this has a historical reason.

[Wood engraving, which is from 1800, that shows

the new decimals units that were legal

in France since November 4 1800.]

The metric system was born in the French Revolution as a way to standardize the patterns in which the units were measured and it was spread to almost all the rest of Europe and also, to the countries that were colonies of that European countries.

That attempt to unify the units of measures never progressed in England and great part of the Anglo-Saxon countries, those that they were already independent, did not want to adapt, being the United States one of them.

The so-called Anglo-Saxon system of units is used in the United States, which varies slightly from the English imperial system. The main units of measurement of it are: inches, feet, yards, miles, ounces, gallons and, in the case of temperature, the Fahrenheit degrees. In order to make clearer the conversions between units of measurements, I would like to share following tables:

EVOLUTION OF THE ELECTORAL STATISTICS IN SPAIN

We are facing an electoral panorama very uncertain and, in turn, numerous since there are several elections around the corner. To help voters get an idea about what the Spanish population thinks, surveys are carried out and graphic representations are formed from that. In order words, statistics are essential in the electoral process . For instance, this is the last survey that collect the voting intenention and what political party will be voted by Spanish citizens. Statistics has been always present in the election period and to illustrate this reality, I would like to expose some significant data collected from the election results from the last decades. The average participation has been 73.79% since 1977, while the year 1982 was the year with the highest participation ( 79.97% ) and on the contrary it was the year 2016 when fewer Spanish people went to vote at the the polls on election day ( 66.48% ) Moreover, the PSOE was the political party with more seats...

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...
