Science/Math article of the week

Math! Though it may be so boring, it is found everywhere. "Count your sheep while you cannot sleep, and don't keep waking me up," your mom indignantly says, and you surprisingly find yourself asleep the next morning. Counting sheep sounds really simple and easy, but this is also math.

Your dad asks the counter, "What will be the price for the computer along with the 27% discount?" It may seem like the counter person is just dabbing in a few numbers on his computer, but he is actually using math to calculate the discounted price.

So what is my point here? Counting sheep? Finding discounts? Am I in a math class or am I supposed to be viewing a blog?
It takes a whole lot of time to do your math  homework, but once you realize you are doing math all the time, wherever you go, consciously or unconsciously, math may seem totally different to you, as you are viewing things from the perspective of your so-called "boring" math.

Even when a few simple things' roots are math, you may find math in the most unusual things you can think of.
Why does my bicycle's training wheels stand unbalanced? Why do camera men use tripods and not a four legged stand? Why does my mom's cooking pot stand have three legs? Three legs or four legs, who cares? Architects and designers care, for if they don't care, their product will be a flop.
Math, math it is, the reason for all this. The reason for why architects and designers meticulously create their products so not a flaw is present.

There is a geometry postulate stating: A line contains at least two points, a plane contains at least three points not all in one line; space contains at least four points not all in one plane.

Postulates are basic assumptions that aren't proved. For example, 2+1=3 is a basic assumption and it cannot be proved. On the other hand, there are theorems that are already proved using basic assumptions like postulates.
To explain that postulate in layman's terms, it means that a line contains at least two points (it's starting and ending), a plane contains three noncollinear points, (three points not all in one line, triangle, for example), and four points cannot all stand in any surface.
So what can we get out of this? Three points can stand in any surface, rocky, rough, smooth, un-leveled, etc. Four points can only stand in a straight, smooth, surface. So now, with the power of geometry, camera men can take pictures anywhere, your mom can cook everywhere, and... that's why your bicycle with training wheels keeps on falling.

Yes, math is the reason for many things, so the next time you say "he does that for some reason," think about math before you ever try to find out.

Riddle of the Week

What always runs but never walks, often murmurs, never talks, has a bed but never sleeps, has a mouth but never eats?

Please comment to post your answer

Science/Math Article of the week

Running is an important trait almost all creatures need to survive, whether they are running from a predator or having fun.

But there is one question, can those big, harmless creatures that are long surviving, elephants run? While most believe they cannot run, scientists have came up with a new observation. 

It is unbelievable, but these creatures can part run and part walk. They run with their front legs and walk with their back legs.
The way elephants move is by converting their potential energy into motion energy.
When elephants lift their foot from the ground, they convert their potential energy, or stored energy into motion energy, and when they put their foot back on the ground the motion energy is converted back into potential energy.
Elephants move like this, back and forth, converting motion energy into potential energy and potential energy into motion energy.

However, while running, the energy cannot be moving back and forth.
It is amazing what creatures do, and how they manipulate their actions to fit their body's ability.

Unfortunately, no one got the right answer. The answer was criticism.

Science/Math Article of the Week

Phobias

Fears! Frightening moments! Phobias!

Wait.. phobias?

What are phobias

Yes, fears are called phobias, and this is the most common problem amongst us humans these days. Phobias are found in almost every creature, from the squirrel that ran away from you today, and the elephant that screamed when it saw a rat (yes, elephants are afraid of rats), and the girl you saw who screamed her head off when she saw a spider.

Fears run through almost every normal human being. Some common phobias are: arachnophobia (the fear of spiders), ranidaphobia (the fear of frogs), and acrophobia (the fear of heights).

Just like animals and earthquakes have classification systems, phobias also have classification systems. There are three categories of phobias: Specific phobia, Social phobia, and Agoraphobia.

The phobia categories

Agoraphobia = the fear of getting into a situation with no escape.
Example: A person who is prone to getting panic attacks can avoid going out of his/her house so he/she      will not get a panic attack outside, where no one can help immediately.

Social phobia = the fear of social events or situation where a group of people are around.
Example: A person who has social phobia can fear going to groups because they might mock him for anything he says.

Specific phobia = the fear of specifics.
Example: A person with arachnophobia is scared of a specific thing, spiders.

The phobia reactions

Physical and mental reactions are possible while getting a phobia.
There are several ways we can react to phobias:

Physical: Hand and leg quivering, shortness of breath, heart pumping, and so on.

Mental: Scared, triggers, and remembrances of bad moments.

What causes phobias

Three ways phobias can form are:

Environmental factors: Our surroundings or past events that trigger our phobias.
Example: If a spider crawled on somebody that must have caused their fear of spiders.

Family factors: Our inheritance, or just "learning" our phobias from our family.
Example: If our parents scream after seeing a cocroach in their house, their children can also learn and become scared of cocroaches.

Biological factors: Chemicals that cause our phobias
Example: If our serotonin level goes low, then we get a phobia.


Source: prior knowledge, did a report on phobias.

Discussion Topic of the Week

This week's topic is:

Is it the world changing around us that makes scientists research more about what is going on, or is it the necessity and need of research that makes scientists research more about this world?

Thanks for the comments on last week's discussion topic!

People had strong choices on whether or not others should point out our mistakes. 

Here are the results:

People should point out our mistakes: 4

People shouldn't point our our mistakes: 4

People who said that people shouldn't point our mistakes and should point out our mistakes' votes got counted on both.

Optical Illusion with Reason of the Week

Today's Illusion is going to be a geometric illusion.

Real life things we see are 3d, as that is how our brain sees it. When we see a 2d image, our brain gets confused, and tries viewing it as a 3d image which can what create an illusion.

An optical illusion is tricks the eyes play to the brain, or tricks the brain play to the eyes. It is usually when our eyes and brain see something in an image that there isn't.

Here is one of the most common illusions:

This is one type of a geometric illusion, where our brain tries to arrange crooked black and white squares into straight lines. This causes us to see the lines in between non parallel, or slanted.

These lines are actually parallel, and are straight.

It is amazing what our brain does to us, and how the tricks make us receive the wrong information.

Quotes of the Week

Clever Sayings!!!

All these quotes are by unknown authors:

A diamond is just a piece of charcoal...
that handles stress exceptionally well.

A little preparation saves a lot of frustration.

All the water in the world cannot sink a ship unless it gets inside of it.
All of the negativity cannot sink a person unless it gets inside of their mind.

                          A rose can live among the thorns and yet never be injured by them.

Current Event of the Week

This may be a favorite post for all those basketball viewers!!

Recently, the Miami Heat won the NBA playoffs, and it was an interesting series. Spurs gave great play, and it went up to game seven!

Each playoffs has a story behind it.. and this year's story is:


In the 2007 NBA playoffs, when Lebron James was in the Caveliers, and the Spurs and Caveliers were playing.
Just then, Lebron James was the most important person in that team, and he was just about the team itself. However, the Spurs beat Lebron and his team 4-0.
This year, in Lebron's new team, he was going to face the Spurs again, and was ready to take revenge.
With a new, and better team he won the 2013
finals, taking the revenge he deserved.

Science/Math article of the week

Scientists just got to know about black holes...

Black holes aren't really holes.. But they are the opposite, just a mass or clump of many things.
As they are invisible, they suck in just about everything that gets near it, including light.
The video above shows a recent discovery how black holes can create beautiful light shows.

Let's talk about the inside of this black hole. As you go inside.. If you go feet down, your feet will be pulled into the center of the black hole, stretching your body like gum. This process is called spaghettification. Eventually, your body becomes a spaghetti noodle and enters the center of the black hole, where everything is kept as a point.

However, black holes aren't just vacuum cleaners in space that take everything that passes by. Only if something gets too close, like a star, the black hole sucks it in.

Recently in Hawaii, people could spot a flare of light from a distance galaxy. This was a black hole sucking in a star that was dying by the black hole. The star was getting shredded into pieces, and because of all the heat the star started glowing, and the black hole started glowing.

Black holes do contain a lot of mysteries, and scientists have a lot to find out!!!
