INTERNET WEIGHT

weightTo 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.

ANALYTICAL BALANCES

Laboratory BalanceResearch 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.

WHAT IS A PRECISION BALANCE

Precision BalanceDigital 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 ANALYTICAL BALANCE

Analytical BalanceThe 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.
