Fibonacci sequence..

Seeds are in Fibonacci spirals

I came across this sequence twice and both were in novels,the famous novel "Da vinci code". and "The Last Theorem" by Sir Arthur C. Clark. They used this sequence to unlock a safe in Da vindi code. As a person of science I wanted to know more and the discovery amazed me. From rabbit breeding to sunflower seeds,to hurricane and galaxies... all are about Fibonacci sequence. So let's get to know what is this magical sequence..
First let me introduce the one who found this sequence..it's Fibonacci,an Italian mathematician and also called the most talented western mathematician in middle ages. He also helped to spread Hindu Arab numerical system in Europe. In 19th century a statue of Fibonacci was built in Pisa. There's a Fibonacci day also..That's 23rd of November.It's a part of the sequence.. (1 1 2 3)

Fibonacci sequence

0  1  1  2  3  5  8  13  21  34  55 89  144  233  377  610  987  1597....

I think you already guessed the pattern correctly..All you have to do is to add two numbers. Next number can be obtained by adding the two numbers before it. Let me  show an example.

0  +  1  = 1                                 0  1  1
1  +  1  = 2                                 0  1   1  2
1  +  2  = 3                                 0  1   1  2  3

Like that it continues..

What's more amazing is when we make squares using the numbers as widths, we get a perfect spiral. Let me show you..

Also any two successive fibonacci numbers have a ratio close to the golden ratio. (Golden ratio is 1/phi and it was used by ancient greeks.) Fibonacci first explained rabbit breeding using the sequence,but with time fibonacci sequence has influenced many of the discoveries in human history.Architecture, Finance, Music,Cinema, Literature and it even appears in some TV dramas. Fibonacci terrace in the science center of Singapore is one of the examples. (For more examples you can visit this site.click HERE) 

Until I meet you with a new story tomorrow,have a nice day friends..!!

Good books for students studying for GCE A/L examination...

As we all know A/Ls is a very tough exam and you will not be able to finish it successfully by just studying.It needs practice,timing and all.So the best way to do it is do exercises and improve knowledge,i did A/Ls in physical science stream and in sinhala medium,so based on my experience i will recommend anyone to use following books.There may be books better than following list,but books below were used by me. Chemistry almost every book by hemachandra basnayaka Akabanika rasayanaya by Aruna Bandara (there are two books for inorganic chemistry,these books will help you in for the doubts you will have in doing mcqs) Akabanika rasayana pilibanda gunathmaka ha pramanathmaka wishleshanaya by Ranga gunarathna(this also will help you in mcqs) Organic chemistry by jayathilaka(this book is very good and it will help you to understand concepts in organic chemistry better) Physics Prof D.D.N balo dayas' books yanthra vidyawa by lakshaman dissanayaka(questionsin this book  are

How to survive A/Ls in 3 months...

Today is the first of May and there are exactly three months until GCE A/L exams begin. I intend to help people who has realized this and started panicking and feeling lost, but not only A/L students but also any student with any upcoming exam can use these tips to ace your exam. I will first explain why most of us usually wait until the day before deadline to do stuff. It's explained by Parkinson's law which states that " Work expands so as to fill the time available for its completion". What it means is, if we are given a week to finish a task we will finish it within the week and if we are given an year to finish the same task we will spend the whole year doing it. Well that's how usually us, lazy humans work. Now that you know what happened there is no time to regret about how we procrastinated on unnecessary things etc. Now it's time to damage control. I will not gurantee you will get 3As by following these. (It's possible depending on

How to get 90+ for GCE A/L Chemistry paper..

Well  for most of the people doing A/Ls in science stream, chemistry is a nightmare, especially for physical science students. So today I'm going to tell you how to write to a chemistry paper in a much different way than you always do. Well it worked for me,and you should test this way with a model paper or in a term test before you go to exam.This saves time and also you can easily score 90+.
