How could the Greek (Pythagoras et al.) measure the frequencies – as they didn’t have a mobile app?



Asked by: Marco Chase

measure the frequencies – as they didn’t have a mobile app? They didn’t have a tuning fork or any other standardized measure. But even without standards they were able to find out the ratios: by measuring strings or weigh pieces of iron.

How did the Greek measure?





The Greeks used as their basic measure of length the breadth of a finger (about 19. 3 mm), with 16 fingers in a foot, and 24 fingers in a Greek cubit. These units of length, as were the Greek units of weight and volume, were derived from the Egyptian and Babylonian units.

What was Greece study involving distance and measurement?

Greeks used different systems of measuring distances and weights, partly taken by Egyptian such as in the Hellenistic age where Greek and Egypt cultures mixed. The same word could mean different lengths such as the stadion length depending when and where it is used.

How did ancient Greeks calculate time?

Sundials. The sun continued to be the primary source of time measurement throughout the Classical Period. Indeed, sunrise and sunset determined the sessions of both the ancient Assembly of Athens and the Roman Senate, and in the latter, decrees decided after sunset were not deemed valid.

How were things measured and weighed in ancient times?

Units of mass



The early unit was a grain of wheat or barleycorn used to weigh the precious metals silver and gold. Larger units preserved in stone standards were developed that were used as both units of mass and of monetary currency. The pound was derived from the mina (unit) used by ancient civilizations.

How do you measure in ancient times?





In ancient times, the body ruled when it came to measuring. The length of a foot, the width of a finger, and the distance of a step were all accepted measurements. Inch: At first an inch was the width of a man’s thumb.

What are the different scales used for measuring length in olden days?

Cubit

  • This scale originated in ancient Egypt.
  • The distance from the fingertips to the elbow was taken as one cubit.


How did ancient scales work?

They consisted of two plates attached to an overhead beam which was fixed on a central pole. Measurements were taken by placing the measured object on one plate and weight stones on the other, until an equilibrium was reached. Archaeologists have discovered these uniform, polished stone cubes in early settlements.

How do bathroom scales work?

The scale works by using pressurised air to balance out the weight of the object, and the amount of air required is therefore used to determine how heavy the object is. The pressure gauge then converts the reading into an electrical signal.



How do scales work?

But how does a scale actually work almost all scales rely on devices called load cells to physically measure how much in object weighs.

How do digital scales work?

A digital scale works best on a flat surface. When an object is placed on a digital scale, its weight causes its internal strain gauge to deform. The scale converts that amount of deformation to an electrical signal, runs the signal through a digital converter, and shows the weight on the scale’s display.

How do you use the Omron digital body weight scale?

Hold your arms out in front of you at a ninety degree angle. When the measurement is complete your weight is displayed. Again you can now scroll through each of the seven Fitness.



Do glass scales work?

Excellent Accuracy



The encoder strip used inside the scales is made of high quality glass that has very low coefficient of thermal expansion; so, the scales have excellent thermal stability. Combined with the mature process of precision photo etching, glass scales are inherently very accurate.
