EASIER THAN YOU THINK...

Measurement

A loosely rolled up measuring tapeGoodness me!  What is it that we don’t measure?

We measure almost everything. Any time that we want to know how much, how big, how heavy, how strong, how clever … or to compare things, we seem to have created a scale for measuring them.

We measure (or attempt to measure) the strength of earthquakes, the pressure in our tyres, our bra/waist/shoe sizes, temperature, humidity, television and mobile phone signal strength, the brightness of stars, the mass of subatomic particles, the strength of magnets, human intelligence, the length of iron sheeting for roofing, the length of nails and pitch of screws, the amount of electricity and water that we use, the pitch of musical instruments, the skill level of gymnasts and divers … and the list goes on and on and on!

This is a wonderful adventure … learning how people throughout history have invented their own ways of measuring the things they value and the things that they want to control or manage.

Basically, measuring is the art of counting applied to quantities/things that are continuous.  In every case, we must invent a scale and have a unit (or standard) against which we compare other things.  I hope you enjoy learning about the history of measurement, the units that we use, about limits to our accuracy … and about money, angles, areas, speeds … and so many other things!

I would describe Graeme as one of the best tutors I ever had. During my school years I spent some time attending one of the major tutoring organizations in town and I found it was difficult for the tutors to spend the time needed to assist me with problem solving due to the class size. My mother rang a private tutor in the phone book who gave her Graeme’s phone number as he specialized in tutoring high school students and was a teacher who used to work at my school. He offered a tutoring service at convenient times which suited our busy life style. The one-on-one service that Graeme provides was what I needed and I saw improvements straight away with my exam results. This made my parents very happy and I found a new confidence in approaching exams. I have since left school but have stayed in contact with Graeme and he has provided me with terrific practical suggestions in preparing for interviews. I would not hesitate in recommending Graeme as a great teacher.
