FORCES (Gaurav Negi)

  My dear Young and Little Indians, Today is the National Science Day of India.   On this day in the year 1928 (28 Feb 1928), Sir C V Raman had discovered what is now called as The Raman Effect .   Sometimes when you ask elders- Why is sea blue in colour ?  They would answer- आसमान नीला होता है और आसमान की छाया समुद्र पर पड़ती है इसलिए समुद्र नीला दीखता है 😊   Sir C V Raman found an answer to it - when light falls on water, lights splits. Water causes blue colour to scatter more than other colours hence we see the sea as blue.   This principle of scattering of light came to be known as The Raman Effect .  Sir C V Raman was honoured with the Nobel prize in 1930.   I hope you all read about Shaheed Chandrashekhar Azad on the FORCES Blog that I had shared with you yesterday.   In the year 1928 , Simon Commission of the British Govt had come to India.  Lala Lajpat Rai protested.

My dear Young and Little Indians,   I met two boys yesterday…. I asked them-   “How tall are you? What is your height?” One of them said he was 168 cms and the other said he was 5 Feet 6 inches.   Now you tell me……  Who of the two is taller ? Why did they express their height in two different ways ? What is the difference between the two ways of measuring height/ length?   They are approximately equal in height but not exactly equal. Right ?   Under the British Imperial System or Imperial System (IS) ….. Units like Pound, Feet, Inch, Gallon, Mile were used for weight, length, volume etc   ·   T hese were confusing and difficult to remember. ·    The multipliers were not standardized. For example- 1 yard= 3 Feet 1 Foot=12 Inches   ·    To make matters worse, every society and country had its own localized units of measurement. ·    When countries trade amongst each other, different units of measurement used by buyer and seller creates
