The mathematics of the barometer

Spectrum recently received convincing proof of the saying that every problem has a number
solutions. The count itself illustrates what a proper economy is and how
It can be explained scientifically. Because the nature of this section is what it is
Occasionally deals with the economic aspects of science and vice versa, Shim Spectrum

It began, 350 years ago, when an Italian physicist and mathematician named
Evangelista Torricelli, filled with mercury a glass bulb length of
90 centimeter, and invented the barometer. But since the days of Evangelista
A lot of money was poured in and the technology became more and more sophisticated. The barometer
himself, even if he changed his form, became and became one of the main devices
In the study of the atmosphere and weather forecasting. However, a barometer turns out to be a face
It is many and strange, and with the help of an appropriate approach, it is possible to find uses for it
Many and varied.

Like for example, measuring the height of a house, in seven different ways as detailed below:
The first method is the scientific method and there is nothing easy about it. Because pressure
The air is known to vary with distance from the sea, that's all
To do this is simply to measure the air pressure on the ground and on the roof,
and calculate the height of the house.
A second method is what can be called the "bucket way". Like dangling a bucket
Tied to a rope to the mouth of the well, laxatives are drawn from the roof slowly and carefully, a barometer
tied with a string. When the barometer touches the ground, stop. Then measure the
The rope and you get what you are looking for.
The third is the one that also utilizes gravity, albeit in a different way
more dramatic. The surveyor goes up on the roof with a barometer in his hand. And there, at face level
The roof, he releases the barometer and lets it fall in free fall to
the ground. Accurate measurement of the time of the fall, (from the moment of release to the moment
the shattering) along with simple physics, will give the distance.
The trigo-barometry is the fourth method. This utilizes the principles
The engineering, and the sunlight. To do this, gently poke the barometer
abroad. Then measure its length, the length of its shadow and of course the length of its shadow
of the house A simple triple value will give the height of the house.
The fifth method is based on exactly the same principles, except this time
Uses sunlight only indirectly. The measurement is simply done on a moonlit night
full. The calculations are the same.
"Heel on the side of the thumb" is the sixth way and it is the most didactic of all. (close
Of course, even the most annoying of them) it is likely that under certain conditions it is too
Put the gauge to a certain pressure. The principle according to which the method works is
Using the pressure gauge as a benchmark. Measure, heel side thumb, some barometers
You "go in" from the floor to the roof, and double the number of barometers you get,
in the length of the device. There are several other "barometric" methods for measuring the height of
houses (e.g. use multiple barometers), but Spectrum leaves it
to the imagination of the readers. Against the background of the variety of techniques presented here, we will see
Because the simplest and most effective method of all is still the best way
L. Y. T.
According to this method, you knock on the door and ask the owner of the house, how tall he is
? In return, they give him the barometer.
