Back On Track

Its been a long time since my last post. Was working on a project. Took me a month to figure out what exactly I wanted to do. Then working on that idea and creating just the basic framework ate away two more precious weeks. And finally when I was upto something...........I see myself getting absurd solutions. What a vaccation it has been! But I guess it is always exciting to work upon original ideas.

More interestingly, there shall be a mathematical project and modelling competition(not the one in which they show off their clothings or the absence there of) coming up for Classes 8th & 9th in the month of August. I was thinking it would be great if we could get some nice projects(more preferably working models) from this event for display and presentation on the day one of Mathematical Crusade.

If anyone is interested in attending lecture by Dr. Tripathi then please do leave some comment- that would at least give me an idea. I need to first convince Jonkai Ma'm, of course, but for that I need some good statistics - response from your side.

Another thing is that I have got two nice graph plotters with me(now please don't expect them to be even anywhere close to Mathematica and stuff- but they have some utility value i guess- it allows you to play around with functions, derivatives, slopes, 3D graphs, and so on). I was thinking if we could get them on this blog. Rasagy is there any scope for this??? Please do let me know.

I am sorry for not being able to upload the questions & solutions of the two events that have been organised till now. I shall try to do it as soon as I finish off with my exams in July.
The certificates for the teams that won in the Sudoku & mathematical Puzzle Solving Contest shall be given out in July as well. The final round of quiz for Class 10th is also scheduled for next month.

(MIT has started an OpenCourseWare programme - that is just a way of saying it has uploaded video lectures, notes & few books on various courses in Mathematics offered at the institute- you would really get to know the reason why MIT is a brand that's a class apart & why it has so many Nobel Laureates in its faculty- the way of teaching is so much fun and beautiful out there- no doubt they produce the best in pure and applied sciences).

Best of luck to the Mathematical Society for the packed heavy schedule next month.

Beauty of Maths!

1 x 8 + 1 = 9
12 x 8 + 2 = 98
123 x 8 + 3 = 987
1234 x 8 + 4 = 9876
12345 x 8 + 5 = 98765
123456 x 8 + 6 = 987654
1234567 x 8 + 7 = 9876543
12345678 x 8 + 8 = 98765432
123456789 x 8 + 9 = 987654321

1 x 9 + 2 = 11
12 x 9 + 3 = 111
123 x 9 + 4 = 1111
1234 x 9 + 5 = 11111
12345 x 9 + 6 = 111111
123456 x 9 + 7 = 1111111
1234567 x 9 + 8 = 11111111
12345678 x 9 + 9 = 111111111
123456789 x 9 +10= 1111111111

9 x 9 + 7 = 88
98 x 9 + 6 = 888
987 x 9 + 5 = 8888
9876 x 9 + 4 = 88888
98765 x 9 + 3 = 888888
987654 x 9 + 2 = 8888888
9876543 x 9 + 1 = 88888888
98765432 x 9 + 0 = 888888888

Brilliant, isn't it?

And finally, take a look at this symmetry:

1 x 1 = 1
11 x 11 = 121
111 x 111 = 12321
1111 x 1111 = 1234321
11111 x 11111 = 123454321
111111 x 111111 = 12345654321
1111111 x 1111111 = 1234567654321
11111111 x 11111111 = 123456787654321
111111111 x 111111111=12345678987654321
