Dear @Vladimir, there are many symbols in science and technology. The following article entitled: "Design and Realization of Symbol Database Based on Multi-interface Symbol Display Technology" by SHI Fulan, ZHANG Shuliang, and  TAO Tao offers Design  of Symbols Based on Multi-interface Symbol Display Technology. Abstract: This puts forword the ideology of share symbol information span different GIS platform. That is multi-interface symbol display technology(MSDT), Realizes the symbol editor which can be visited by different GIS platform directly,MSDT supplies different interfaces for almost all GIS software, internal and overseas, and all these interfaces are validated by series of product of Map Object and Arc GIS of corp. ESRI, also are validated by MapX of corp. MapInfo and also are validated by Supermap ,internal GIS software. See the paper at the link:

Dear @Vladimir, according to Merriam Webster, scientific symbols are "standardized signs that have been adopted by convention to simplify the writing of numbers, formulas and equations used in science and technology."

In my area of industrial automation and control engineering I do use GRAFCET and GRAFCHART symbols, FBD, LADDER, Logic Symbols..... Many of them are available through different editors and tools.

Thanks to Prof. Vladimir D. Ilyin for It’s really an interesting question and same time thanks to Prof. Abedallah M Rababah for very interesting answer. It is very useful to me for got a new idea please.

Dear @Abedalahh and @Ljubomir, thank you for your answers that relate to visual symbols.

How do you explain the growing popularity of computer devices with touch screens? 

How do you assess the prospects for the development of gestural interface?

Chemistry & chemical technology use symbols very often for various purposes. For example, each element has a symbol  which is universally accepted. When one sees "Na" symbol this indicates sodium metal, 1 atom of sodium, and 1 mole of sodium (i.e. ~ 6 X 10 23 atoms which are equal to ~ 23 grams of  this metal). When there is a compound, the symbols are combined in correct proportions to give a formula. Example: CH4 stands for the methane gas, denotes 1 molecule of methane, and indicates 1 mole of methane (i.e. ~ 6 X 10 23 molecules which are equal ~ 16 g of this gas). Add to it, CH4 may be considered as 1 volume of the gas which equals 22.4 liters at STP (another symbol which refers to satandard temperature& pressure; the first is 0 oCelsuis & the second is 1 atmosphere or 760 mm Hg "mercury" ).

This science relies a lot on symbols so as these are called " the language of chemistry". When 2 chemists talk with each other about this subject, a third person nearby may need a translator! even though all 3 may be British. 

Dear Dr. Nizar Matar, 

Thank you for your example of the use of visual symbols in chemistry.

Dear Vladimir,

Thanks for the nice topic, I have two points to share -
