Mission of the course

3

Enables the students to learn the techniques and standard practices inmetrology

At the end of the lectures, one would be able to:

Have clear idea of challenges in metrology due increasing trend towardsminiaturization

Understand many different metrological devices and principles andapplicability of those devices

Understand the process and provide metrological solution for thebetterment of part or process

The Lab

6

• In order to understand some basic principles and measurement methods available in metrology, a 2 hour lab demonstration will be held during the term.

• Students should get the relevant details and this will be required for doing a project which may have some experiments.

• Note: Safety is of utmost importance. So group of students must work together and will be helped by researchers in the lab.

What is Metrology?

8

Metrology is the science of measurement, embracing both experimental and theoretical determinations at any level of uncertainty in any field of science and technology.

Why is it important

9

• When you can measure what you are speaking about, and express it in numbers, you know something about it;

• But when you cannot express it in numbers, your knowledge is of a meager and unsatisfactory kind.

• It may be the beginning of knowledge, but you have scarcely, in your thoughts, advanced to the stage of science.

The "Royal Egyptian Cubit" was decreed to be equalto the length of the forearm from the bent elbow tothe tip of the extended middle finger of the hand ofthe Pharaoh or King ruling at that time.

Although standardization has been a goal of social andeconomic advancement since very early times, only in18th century that there was a unified measurementsystem.

The earliest systems of weights and measures werebased on human morphology. Consequently, theseunits of measurement were not fixed; they varied fromone town to another, from one occupation to another,and on the type of object to be measured.

This lack of a standardized system of measurementswas a source of error and fraud in commercial andsocial transactions, putting a brake on internationalcommerce and prevented the development of scienceas an international endeavor.
