The secrets of pi

One of my favourite numbers is between 3.2 and 3.1 called pi. I know a lot about it so lets get straight in to the information. The formulae of pi is ' r squared x pi=c' because r means the radius of a circle and c means the circumference of a circle so the radius of the circle times pi=the circumference of a circle. The first fifty digits of pi are '3.1415926535 8979323846 2643383279 5028841971 6939937510  I have already memorised the first 20 digits of pi. Here is the first page of the book 'The Secrets Of Pi' The Secrets Of Pi Chapter 1 Everything you always wanted to know about pi  but were afraid to ask p is the most famous number in the world, the most studied, the most calculated, the most referenced…But nevertheless there is little definite that can be said about p . To begin its decimals start in this way: 3.1415926535 8979323846 2643383279 5028841971 6939937510 and with those fifty magical digits one can navigate aroun...

The 7 Bridges of Konigsberg

Image
Not too long ago I found out about a maths problem called "The 7 Bridges of Konigsberg". Here's the problem, The people of Konigsberg want to try and go across all 7 bridges only once. See if you can cross all 7 bridges without crossing any more than once. Now try taking one bridge away like this: Visit the link to see all the detail. its fun to try different bridges to see if you can complete the challenge.  http://mathforum.org/isaac/problems/bridges1.html

powers of 2

I love the powers of 2 because I found out that they are used in 2 of my favourite things:binary and prime numbers. Here are the powers of 2 up to 83. 0 1 1 2 2 4 3 8 4 16 5 32 6 64 7 128 8 256 9 512 10 1,024 11 2,048 12 4,096 13 8,192 14 16,384 15 32,768 16 65,536 17 131,072 18 262,144 19 524,288 20 1,048,576 21 2,097,152 22 4,194,304 23 8,388,608 24 16,777,216 25 33,554,432 26 67,108,864 27 134,217,728 28 268,435,456 29 536,870,912 30 1,073,741,824 31 2,147,483,648 32 4,294,967,296 33 8,589,934,592 34 17,179,869,184 35 34,359,738,368 36 68,719,476,736 37 137,438,953,472 38 274,877,906,944 39 549,755,813,888 40 1,099,511,627,776 41 2,199,023,255,552 42 4,398,046,511,104 43 8,796,093,022,208 44 17,592,186,044,416 45 35,184,372,088,832 46 70,368,744,177,664 47 140,737,488,355,328 48 281,474,976,710,656 49 562,949,953,421,312 50 1,125,899,906,842,624 51 2,251,799,813,685,248 52 4,503,599,627,370,496 53 9,007,199,254,740,992 54 18,0...

Powers of 3

Another thing I love about maths are the powers of  3. I like it because it's very challenging and helps your calculating improve. here are some of the powers of 3: Powers of three: 2 9 3 27 4 81 5 243 6 729 7 2187 8 6561 9 19683 10 59049 11 177147 12 531441 13 1594323 14 4782969 15 14348907 16 43046721 17 129140163 18 ...

Prime numbers

One of the first things I started loving about maths were prime numbers. A prime number is a number that can only be divided by itself and one. In other words it can not be broken down into any smaller whole numbers, which in this case are called factors. These are a few special facts about a prime number: There are infinite prime numbers 2 to the power of a prime number-1=another larger prime number One of the of the main things that you will need to know about that second fact is that you can not use any prime number to do that some. That's because 2 to the power of 11-1=2,047=23x89 which means it is not prime, but these are all prime numbers: 2 to the power of 13=8,191 2 to the power of 17=131,071 2 to the power of 19=524,087 Which are all prime numbers! I started loving prime numbers when I watched this ted talk about the search for monster primes. I liked this video because it reminds me how if you stay focus on one thing you can achieve anything. This video is p...

Welcome

Hi everyone. I have created my new blog because I want to inspire kids who are gifted or talented with mathematics and feel confident for a challenge and want to take it a step further. You can have fun learning a few little bits and pieces of the whole wide world of mathematics. You can find out about new websites that might interest you and and make you work harder. Here is something that really inspired me about maths and to start working harder. click here
