PI PI MATHEMATICAL PI!!!

Hi everyone! It's been long since I last posted!! Sorry for neglecting the blog for a couple of months!!!

Well, I was browsing through some information about Pi Day (Yes, we might be celebrating it... I HOPE!!!) when I stumbled upon an interesting song called the "Pi Pi Mathematical Pi" song... It's rather catchy... Hahax! It's kind of cute, funny but at the same time rather meaningful...

Hope you enjoy listening and singing it! Hahax! Here are the lyrics!

PI PI MATHEMATICAL PI
by Antoni Chan and Ken Ferrier

A long, long time ago,Long before the Super Bowl and things like lemonade,
The Hellenic Republic was full of smarts,
And a question resting on the Grecian hearts was;
What is the circumference of a circle?",
But they were set on rational numbers,
And it ranks among their biggest blunders,
They worked on it for years,
And confirmed one of their biggest fears,
I can't be certain if they cried when irrationality was realised,
But something deep within them died,
The day, they discovered, Pi.



They were thinking;
Pi, pi, mathematical pi,
3.14 15 92,
65 35 89 7,
932384 62,
6433832 7 (not rounded).



Well this kind of Pi is different than most,
It hasn't got berries,
ain't spread on toast,
And that's how it's always been,
We keep extending its decimal places,
Pushing our computers through their paces,
But we'll never reach the end,S
o why the fascination with,
A number whose end is just a myth?Whence the adulation,
For mental masturbation,
It might have something to do with the stars,
To calculate distances from afar,
But that's just a guess 'bout the way things are,
Regarding the precision of Pi,



I am pondering;
Pi, pi, mathematical pi
3.14 15 92
65 35 89 7
932384 62
6433832 7



Now I feel that I should mention,
Pi is applicable in any dimension,
At least as far as I know,
If there were no Pi we'd be missing things,
Like marbles and mugs and balls of string,
And sports, such as soccer and curling,
The orbs in their celestial paths,
Navigate along elliptical graphs,
Ellipses have pi in them too,
Just one side of them has grew,
You can see pi in most everything,
It's in Cornell's Electron Storage Ring,
And also in slinkies and other springs,
And that's why it's important to know pi,



You should memorize,
Pi, pi, mathematical pi,
3.14 15 92,
65 35 89 7,
932384 62,
6433832 7,



Once one night I had a dream,
That pi was gone and I had to scream,
Cause all pi things had disappeared.
Can you imagine a world like that?
Circles aren't round and spheres are flat,
It's the culmination of everything we've feared,
'Twas a nightmare of epic proportions,
One that gave me brain contortions,
Oh wait! I mean contusions,
They put me in some institutions,
But then I escaped and now I'm free!
To sing of the virtue of pi,



Pi, pi, mathematical pi,
3.14 15 92,
65 35 89 7,
932384 62,
6433832 7.

Enjoy!!!

A Warm Thank You

A warm thank you to the Form 5 and Form 4 Mathematics and Science Society 2009members who participated in this year's activities and discussion as well as those who lend a hand in bringing the club to greater heights and as well as contributing the wonderful thougths and ideas which was brought up during our meetings .Our farewell party 2009 will be held most probably after the SPM (Sijil Pelajaran Malaysia )2009 trials Examination.Wishing all the Form 5 members good luck and all the best in their examination as well as in their future challenges in life . In addition , we always hope and try our best to bringing the Mathematics and Science Society to even greater heights .

Mathematics 13 facts

1) 1 googol = 10100;
1 googolplex = 10googol = 1010100 .

2) 1089 multiplied by 9 gives an exact reverse: 9801.

3) From 0 to 1,000, the letter "A" only appears in 1,000 ("one thousand").
2 is called the "oddest" Even Prime-number. 2 is a unique Even Prime because all Even-numbers are divisible by 2. But any number apart from 2 that is divisible by 2, is not a Prime. Sciensational.com


4) 1 × 9 + 2 = 11
12 × 9 + 3 = 111
123 × 9 + 4 = 1111
... and so on.

5)40 when written "forty" is the only number with letters in alphabetical order, while "one" is the only one with letters in reverse order.

6)Multiplication and succession: 142857 is a cyclic number, i.e., its digits are rotated around when multiplied by any number from 1 to 6. Like this:

7)142857 × 1 = 142857
142857 × 5 = 7 14285
142857 × 4 = 57 1428
142857 × 6 = 857 142
142857 × 2 = 2857 14
142857 × 3 = 42857 1


8) 1 × 8 + 1 = 9
12 × 8 + 2 = 98
123 × 8 + 3 = 987
and so on.

9)The opposite sides of a dice cube always add up to seven.

10)If you add up the numbers 1-100 consecutively (1+2+3+4+5...) the total is 5050.
The billionth digit of Pi is 9.
1 and 2 are the only numbers where they are the values of the numbers of factors they have.
11)2 and 5 are the only primes that end in 2 or 5.
12)The largest prime number is 9,808,358 digits long; more than the number of atoms in the universe. Sciensational.com

13)The digits to the right of the Pi's (3.141...) decimal point can keep going forever, and there is no pattern to these digits at all.

Invention

Our society conducted an activty called ' Inventors of the day '. Members was explained to the rules and themes provided . Each member was given an A4 size paper . The members was asked to draw and describe their invention based on the following themes :

a) Create an organism and describe it's features .
b) Create an invention which could help lessen mankind's burden .
c) Create the ultimate 'fruit'.
d) Create an new organ in the human body .
e) Create a new mathematical game .

The members were very participative and all in all put a good spirit of the ideas .

Plastic Milk Experiment

Our club did an experiment called the ' Plastic Milk ' . This experiment was particpated by the society members according to a procedure on the experiment . The experiment was held in the Biology Lab in our school and referring to the procedures as below :

PLASTIC MILK

One cup of milk
4 teaspoons of white vinegar
A bowl
A strainer
Adult help

Ask your friendly adult to heat up the milk until it is hot, but not boiling
Now ask the adult to carefully pour the milk into the bowl
Add the vinegar to the milk and stir it up with a spoon for about a minute
Now the fun part, pour the milk through the strainer into the sink - careful it may be hot!
Left behind in the strainer is a mass of lumpy blobs.
When it is cool enough, you can rinse the blobs off in water while you press them together .
Now just mold it into a shape and it will harden in a few days. - Cool!

Plastic? In milk? Well, sort of. You made a substance called CASIN. It's from the latin word meaning "cheese." Casin occurs when the protien in the milk meets the acid in the vinegar. The casin in milk does not mix with the acid and so it forms blobs. True plastics, called poymers, are a little different. If you want to make a true plastic and learn more about polymers, try the Homemade Slime experiment. Have fun!

THE WORLD’S EASIEST LAVA LAMP!

MATERIALS & APPARATUS

• ~A clean 1 liter clear soda bottle
  ~3/4 cup of water
  ~Vegetable Oil
  ~Fizzing tablets (such as Alka Seltzer)
  ~Food colouring

PROCEDURE
1. Pour the water into the bottle.

2. Use a measuring cup or funnel to slowly pour the vegetable oil into the bottle until it's almost full. You may have to wait a few minutes for the oil and water separate.

3. Add 10 drops of food coloring to the bottle (we like red, but any color will look great.) The drops will pass through the oil and then mix with the water below.

4. Break a seltzer tablet in half and drop the half tablet into the bottle. Watch it sink to the bottom and let the blobby greatness begin!

5. To keep the effect going, just add another tablet piece. For a true lava lamp effect, shine a flashlight through the bottom of the bottle.

HOW DOES IT WORK?
To begin, the oil stays above the water because the oil is lighter than the water or, more specifically, less dense than water. The oil and water do not mix because of something called "intermolecular polarity." That term is fun to bring up in dinner conversation. When you added the tablet piece, it sank to the bottom and started dissolving and creating a gas. As the gas bubbles rose, they took some of the colored water with them. When the blob of water reached the top, the gas escaped and down went the water. Cool, huh? By the way, you can store your "Blobs In A Bottle" with the cap on, and then anytime you want to bring it back to life, just add another tablet piece.

TRY IT YOURSELF!
The project above is a DEMONSTRATION. To make it a true experiment, you can try to answer these questions:

1. Does the temperature of the water affect the reaction?

2. Does the size of the bottle affect how many blobs are produced?

3. Does the effect still work if the cap is put on the bottle?

4. Does the size of the tablet pieces affect the number of blobs created?

* Hey Math & Science members! Wanna try doing this experiment?! I believe we'll have loads of fun doing it together!!

COOL ILLUSIONS!

Illusions are images that use your EYES to confuse your BRAIN

Take a look at this grid:
Did you notice the small grayish dots between the black boxes. They are not part of the drawing - they were put there by your brain! Scientists call this "visual vibration." Basically it means that when you see patterns of black and white, your eye sometimes confuses the two and blends them into patterns of gray that you see here. You are seeing something that is not really there!

This elephant is missing a leg...or is it? The artist confuses his viewer by changing they way our brain is used to seeing things. It seems the more you look at the elephant, the more confusing it gets.

Want to see the gears move? Look at the dot and then move your head towards the screen and away from it.

This uses visual vibrations to create a cool effect. Try moving your head close to, and then away from the screen. The fuzzy dots appear to move.

This simple line drawing is titled, "Mother, Father, and daughter" (Fisher, 1968)because it contains the faces of all three people in the title.How many faces can you find?

Look at the dots in the center. Which one is bigger?Like many similar illusions, the dots are the same size...really!It can be hard to tell because your eye uses the other dots to make a comparison.

Check out the spiral...except it is not a spiral, just circles.Don't believe me? Use your finger to follow the fake spiral.The tilt of the boxes fools your brain into believing it is a spiral.

Hey, this is weird. It looks as though it's moving, but it's not. The shapes confuse the eye (really the brain) into believing that they are moving.

MATH N SCIENCE ROCKS!!!!!

YAY!!!
This is our very first achievement of the year!
This is the first time our club managed to secure a rather "sought-after" title of the year!


Best Notice Board of the Year goes to Math & Science Club!

All thanks to our very own, Notice Board commitee, comprising of Wen Lin, Sok Cheng, Rebecca and I and of course all the members of the club~!

We love this board! It made us really proud! We'd carved a name for ourselves!

Our faces glow with ultimate pride when we see our schoolmates stop by and read the articles on the board!

We promise to bring more pride to our club by securing another similar title for the second-half of the year!

Coca - Mentos Experiment (7th April 2009)

We had loads of fun getting together, conducting fun and easy experiments and at the same time learning some interesting scientific facts!!

This is a brief scientific report on the experiment:

Aim

To investigate the reaction between Diet Coke and Mentos candies

Hypothesis

The reaction between the Diet Coke and the Mentos candies results in an eruption.

Materials

A handful of Mentos and two liter of Diet Coke

Procedure

8 Mentos candies were dropped into a bottle of Diet Coke.

Observation

An eruption occured.

Inference/Explanation

This reaction was thought to occur because of rapidly expanding carbon dioxide bubbles inside once the Mentos were introduced to the carbonation.

Caffeine, potassium benzoate, aspartame and carbon dioxide gas contained in the Diet Coke and the gelatin and gum Arabic ingredients of te Mentos all contributed to the geyser effect.

When Mentos candies were dropped into the Diet Coke, the gelatin and gum Arabic of the candy dissolved and broke the surface tension. This disturbed the water mesh, so that less work were needed to expand and form new bubbles. Each mentos candy has thousands of tiny pores all over its surface. These tiny pores function as nucleation sites, perfect places for carbon dixide bubbles to form. As soon as the Mentos entered the coke, bubbles were formed all over their surface. They quickly sinked to the bottom, causing carbon dioxide to be released by the carbonated liquid with which they came into contact along the way. The sudden increase in pressure pushed all of the liquid up and out of the bottle.

Discussion

1) Why do we use Diet Coke instead of the regular Coke?

The reason that people use diet coke is because they do not contain sugar like regular coke. Non-diet coke contains a large percentage of sugar molecules, which help hold onto the carbon dioxide a lot better, thus preventing nucleation from occuring as quickly, resulting in a weaker reaction.

The absence of sugar in the diet coke residue after the geyser effect caused the resulting mess to be non-sticky and this makes clenup much easier.

Conclusion

The reaction between the Diet Coke and the Mentos candies results in an eruption. Therefore, the hypothesis is accepted.
