“Measurement Is a Process of Obtaining of Valuable Information,” Says Professor Hristo Radev from Bulgaria


The Second International Science-to-Practice Conference “Measurement: Status and Prospects of Development” has been held at South Ural State University. The most prominent scientists in the field of metrology from Great Britain, Bulgaria, Kazakhstan, Belarus, Russia and other countries took part in it.

SUSU has many years of experience in successfully training specialists in metrology, as well as in developments, manufacturing and application of measurement instruments. That is why for the second time our University acted as an organizer of this big-scale event.

The Chairman of the Bulgarian Union of Metrologists, Professor Hristo Radev delivered his speech for the conference participants. In his presentation the Professor paid special attention to the issue of selection and application of the associated feature when evaluating the form and location of surfaces and axes of workpieces in mechanisms.

Hristo Radev noted that the SUSU international forum is very important for development of various fields of science.

− The conference is dedicated to discussing of the current achievements in the field of development, manufacturing and application of measurement instruments. Why is this issue topical today?

− Lord Kelvin once said that “…when you can measure what you are speaking about,..you know something about it…” You cannot do much without measurements since everything in this world gets measured and compared. This is a process of obtaining of valuable information. All the results that we receive have but one purpose – what we take these measurements for? This may be a solution at a utility level, or at a rocket control level, and so on. Information is the most valuable asset at the market right now.

− Do you think the issues raised by the conference presentations are topical?

− The conference agenda is very wide, it covers various topics related to metrology, measurement in social and humanities field: measuring human emotions and behavior and things like that. These are the topics that impressed me much. Every year I organize a big international symposium on measurement equipment, and we have a section on “Measurement in Humanities”. Namely this issue is being discussed today, and I am very happy about it.

− What was your way to science? Why did you choose metrology?

− I graduated from Moscow Machine Tool Institute. My first job was at a plant where I was dealing with development and implementation of measurement equipment. Then I came to a university to lecture on measurement, first on mechanical and then on geometric measurement. After that I established a laboratory where I took on developing measurement instruments, mostly for the defense industry. I was fascinated by this issue, and I still keep working on it.

− What are your current studies dedicated to?

− My colleagues and I are working on the form of positioning of big-size objects, for instance of turbine shafts and rotor shafts. These weigh 80 tons and are 7 meters long, and they also require geometry in the range of several micrometers. If a human hair’s diameter is 50 micrometers, then you can imagine what such a requirement means! 

− What do you think of your collaboration with SUSU?

− I got to know about SUSU when I was invited to the first conference back in 2013. Then our fruitful relationships with the managers and colleagues working in the field of measurement started, and we signed a collaboration agreement. We also carry out joint research. I have recently delivered a lecture for the SUSU students regarding steelworks support for machine-building production. I hope that our collaboration will go deeper in the future. SUSU is striving to achieve ambitious goals – to be listed in Top 100 of the world universities, and the fact that it is located at the intersection of Europe and Asia gives it a big advantage in it. The University makes an impression not just by its scale and equipment, but most important by people who work here. I believe that SUSU is one of the most progressive universities in the Russian Federation.
