Project Euler

Quite recently, I stumbled upon this so called Project Euler, named after famed German Mathematician. It is a collection of challenging mathematical questions.
Here is the description from the website:

Project Euler is a series of challenging mathematical/computer programming problems that will require more than just mathematical insights to solve. Although mathematics will help you arrive at elegant and efficient methods, the use of a computer and programming skills will be required to solve most problems.

The motivation for starting Project Euler, and its continuation, is to provide a platform for the inquiring mind to delve into unfamiliar areas and learn new concepts in a fun and recreational context.

Good luck in trying some of the questions XD

About Relativity

Quite recently I stumbled upon similar rhythmic lines describing Theory of Relativity, mainly from the book Hyperspace and A Briefer History of Time.

There was a lady of Wright.

Who traveled much faster than light.

She departed when the sky is bright.

And returned on the previous night.

Since the source are not identical, I changed it to this, without changing much of the meaning behind it.

Life goes on

Yesterday was a blast, at least not for my wallet. 08S09 peeps were as usual, the only downside is we do not have much topic to talk about. No anime, not much games, no educational debate. Almost the entire thing was dominated by NS, NS and NS. We had sushi for our lunch and unfortunately someone forget to pay me money. Hey people, I still waiting for the cash.

The movie was so so, not as exciting as the title suggest. After the movie, I went to Kinokuniya to buy some books (Broca's Brain written by Carl Sagan and another book on theory of relativity). You guys should had known why I bought those books. XD

Surprising Number Pattern

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

Interesting Pattern

Have you ever noticed this?


11^2 = 121
111^2 = 12321
1111^2 = 1234321
11111^2 = 123454321
...
111111111^2 = 12345678987654321
1111111111^2 = 1234567900987654321
and so on.

How true is this?

When I was bored enough during maths lesson, I jotted down some prime number and find something rather surprising. Prime number that is larger or equal to 7 can be re-represented as the sum of three prime numbers. in short, d = a+b+c where a,b,c and d are prime number and d≥7.

Some example up to prime number that is less than 100 would be :
7=2+2+3
11=2+2+7
13=3+3+7
17=5+5+7
19=7+7+5
23=11+5+7
29=23+3+3
31=23+3+5
37=31+3+3
41=31+5+5
43=31+5+7
47=37+5+5
53=43+5+5
59=53+3+3
61=31+13+17
67=61+3+3
71=61+5+5
73=67+3+3
79=73+3+3
83=73+5+5
89=79+5+5
97=41+37+19

Enough of spamming out of the blue.

I Have a Dream

I have a dream
To know more about the cosmos
Seeking the truth behind its origin
And how it will end

I have a dream
To understand life better
Discovering how it starts
And how it diverge

I have a dream
To educate the world
Teaching them the truth of the universe
Out from the tyranny of religion

I have a dream
To protect the planet
That does not belongs to us
Yet we call it home

I have a dream
I will fight for it
Nothing will stop me
No matter what
