The lessons taught in term 2 are indeed interesting. We learnt the instruments of measurements, the vernier caliper , micrometer screw gauge and the metre rule. We also learnt the SI units and its importance. SI units were created to standardize the measurement. Before this, there was complete chaos. The Egyptians used the length from the elbow to the hand as one cubit. Anyone can spot the loop hole here. When you sell your house, just use a child's arm and you are sure to be a millionaire overnight. Therefore, the king instructed that one cubit would be marked out using his arm. The effects were almost immediate as the Egyptians built the pyramids using this standard unit.
Term 2 has made me realise that many things around me are all science's doing. Sometimes, I imagine, what if there was no SI units, no micrometer screw guage, no vernier calliper, what would the world be like?
