To evaluate the mass of the internet, analysts multiplied the mass of ONE electron (9,1 x 10 to the power of 31) plus the common weight which powers this electron WITH the number of electrons required to post and keep web data in the our planet. They wound up with the total weight of 50 grammes. This might be a surprisingly trivial number given the ubiquitousness of internet in our everyday life.
But, if electrons have weight then by what means do they change the weight of our everyday equipment (notebooks, iPod’s, iPad’s etc.)? Indeed, the weight of the devices bit by bit increases with the increase in the amount of data. To be more precise, this increase of weight is due to the increase of weight of the particular electrons which need more energy to store data. Having said that, this rise of weight is evidently small and unquestionably impossible to dicern by the user.
Hopefully, this article helped you to look at the internet and data in a whole new perspective.

Research laboratory balances, depending on the efficiency of the measure can be divided into: industrial precision balances, semi-microanalysis weights and analytical balances. These and the other may be a common or professional. The latter have the top specs and are very ergonomic. Usually also feature a touch screen and a printer, which is used to print the measurement part of the reports.
The most accurate
Precision balances with the top accuracy of d = 0.01 mg is the weight semi-microanalysis. They are exercised in analytical laboratories during a very precise measurement of the samples. The highest measurement efficiency is due to a built-reported weight filters to withhold noise from the outside, vibration and air blowers. While the owner of the laboratory decides to buy a semi-microanalysis weight, he/she must also invest in a certain anti-vibration table. It is also cardinal to control a stable temperature in the room.
The world’s most powerful
Those are less precise analytical balances with the sharpness of reading equal to d = 0.1, and so it is ten times smaller than in the semi-microanalytic weight. Analytical balances are also highly resistant to mechanical destruction. Analytical balances can have a weight of conventional systems. Precision balances, the preciseness of which is 0.01 g 1mg group are the most popular instruments used in laboratories. You may even find that in any modern laboratory find at least one of such importance.
In the course of the centuries the most recognizable category of weights used were ‘traditional’ beam balances. The introduction of electricity reformed the weighing industry. Since the 19th century many new types of weights (based on electricity) have come into view. Some of the examples of electricity-powered balances used nowadays are:
As the name suggests, they are most frequently encountered in numerous industries (transport, trade and agriculture, warehouses etc.) where they are used to weight objects up to several hundred tones. Resistance to decay, extreme temperatures, humidity and acid makes them the most damage proof scales in the world.
Recent technological inventions have enabled us to measure not only the weight of a person but also their BMI (Body Mass Index) as well as the percent of the body fat. Maximum load found in most personal balances ranges around 150 KG.
Usually settled on the ground, they are used to weigh the front axle load. The driver steers the car which runs on the scale.
Most frequently used in medical and jewelry businesses, they are used to assess the weight of extremely small, sometimes microscopic-like, objects with accuracy up to 1 nanogram. Only electronic weights can reach that level of precision.
Those who like to cook and follow different recipes use kitchen scales to measure the weight of e.g. flour or grits.
The earliest evidence of the use of balances can be traced to 2400-1800 B.C. There are also many convincing traces which suggest that weighing system was broadly used by the Egyptian civilization. The first recorded form of a weighing device other than the balance occurred in 400 B.C. and was known as the Bismar.
Its construction included a rod of wood with a large weight fixed at one end. The Romans invented the steelyard in 200 B.C.Originally known as the statera, the English word steelyard comes from the German Stalhof, the name of the London base of the Hanseatic merchants of the Middle Ages, who used the instrument extensively in their businesses. A historical figure who designed the first self-indicating scale was Leonardo Da Vinci.
The next step in the evolution of the balance was the focus on the knife-edge as a pivot of the scale.Illes Personne de Roberval. Roberval discovered the Static Enigma, which was to defy explanation for the next hundred years. Machines to weigh large loads began to develop during the eighteenth century towards the end of the 19th century, the technology of weighing machines began to develop into the type of machines we would recognize today.
In 19th century inventors began to consider and implement the types of scales which would be programmed to estimate the value of goods. In the late 1940s mechanical weighing began to combine with electronics.
Digital and precision scales belong to the inventions of the digital age. A digital scale is a weighing device in which the weight or mass of a material is displayed in digital numbers. Today, precision balances most commonly can be found in the pharmaceutical industry and chemical companies.
Having said that, there are also other places where precision balances are used, e.g. educational facilities. Technology found in the recent weights enables automatic calibration on any surface. This gives exact results every single time. In the older types of scales the user had to calibrate the scale every time before using it, which affected the comfort of use. With the implementation of auto calibration that problem has been done away with. The scales now calibrate on their own, making sure you get the best reading every time.
The history of analytical lab balance dates back to 1945 when Mettler Toledo company founder Erhard Mettler introduced the first Single-pan analytical balance. Large-scale production of Toledo weights began in 1946. Nearly three decades later, in 1971, the first nanogram balance was introduced.
The first fully electronic precision balance, PT1200 scale, appeared on the market in 1973. A new force restoration technology was introduced in 1989. It eliminated many hand assembly steps, assured manufacturing quality control and, ultimately, reduced cost. Soon after, in 1993, the new Mettler Toledo electronic microbalance with a 51 million point resolution was introduced.
The first ultra-microbalance with a weighing capacity appeared in 1996 and the first monolithic weigh cell technology was introduced in 1997. Himadzu Windows Direct communication function introduced many new useful mechanisms in lab scales such as: record weight or computed values generated by the balances. The latest innovations include: adding a color touch screen, Bluetooth connectivity in 2005, 61 million digit resolution in 2009 by Mettler Toledo XP6U.
