An interesting CIE Math Guest lecture!!!

Guest Profile:  The guest Debashish Banerjee, has 8 years of experience and Specialized in Analytics, Predictive Modelling, Data Mining, Insurance. He is a Practice Leader for Actuarial, Risk and Analytics at Deloitte Consulting Hyderabad .He graduated from Indian Statistical Institute. 

On Monday, 30 September, 2013, Mr. Debashish Banerjee came to Oakridge to share his views to 10^th graders (IGCSE) on using statistics on everyday life. We all gather in 9^th H and were waiting eagerly for him to come and give us information on statistics. Mr. Debashish started with  the first invented number, zero (0).We got to know, when zero was invented ,by whom and some principals such as sum of zero and a positive number is always a positive number, zero multiplied with a number is always zero etc. Later on, he scatted some interesting facts about statistics. According to me there are two facts that were absorbed by my brain: The pigeon principal and The teapot kettle. Mr Debashish talked about an interesting number “1729”. The interesting fact about this is that when you add all these numbers and multiply the answer with the reversed answer you will end up with the same number! There are only three numbers which follow this principal: 1729, 81 and 1.  He also touched about the surveys and how to deal with them if they are sensitive. We all were tangled with the birthday problem which was given before the teapot kettle. On the whole, the talk was very informative and interactive. 

Conclusion:  Finally, at the end of the lecture everyone was thankful to know about the Fascinating point on statistics.

We, the students thanked him for this interactive session by giving a gift behalf of the school.

On September 31st, 2013 the students of Grade 10, IGCSE were given a guest lecture by Mr. Debashish Banarjee, in relation to their ongoing statistics unit. Mr. Banerjee majored in statistics and now works with a consulting company.

 First Mr. Banerjee told us a few interesting math stories, some of which really astounded us. First, he started off by talking about the invention of ‘0’ and other number systems such as the binary and hexadecimal system. He then moved onto some extremely simple and seemingly obvious principle, such as the Pigeonhole Principle and the Teapot Principle, and their astounding consequences. He also told us about the significance of the number ‘1729’. Next, Mr. Banerjee spoke about surveys and the trouble they often have when faced with sensitive questions. He also told us how the overcome this problem using randomization.

Overall, this lecture was extremely interesting and enlightening experience and gave statistics a new light.
