Physics At The T-Shirt

In Jogjakarta, Indonesia, there are five member of Physics Olympics in Croatia. One of them is Ataka Awalur Rizki, that at the moment he still be the student of SMAN 3 (State High School) Yogyakarta. He get the predicate as runner up (Silver Medals) at this Olympics. But at the other story, Ataka is the young Enterpreneur of Jogjakarta. Now, he is study ini Electrical Engineering Of Gadjah Mada University and have a big bussines: "Smart T-Shirt". We can see it in http://kauspintar.com. Ataka and the parents have spirit to make Physics is Simple to everyone. The simple formulas of Physics are wrote at the T-Shirts. So the discover such as Newton, Edison, Galileo, Archimedes story were wrote at the T-Shirt.

At the site http://kauspintar.com, we also can order it via online. With his online staff, Ataka and his business can develop the Physics World.. So make it simple the Physics with T-Shirt!!

Anti Color Blind Test

Our eyes have color filter. In the normal filter we can say:"Normal Blind" or "No Color Blind". But if the filter eyes are different with the majority, they are called "Color Blind". To check your level color blindness, you can use the test below:

Fig 1

If you see all of the number in the test specimen, you have no color blindness. If you can see one or all of the pics, you have a normal filter, so the other man can say that you are : Color Blind human. The simulation of how color blindness human see, can look below:











The test image can interpret by color blindman as:




So, You can continue with this picture:









Can you see that the picture is : LETTER 6? If you can, you have a color blindness. The answer of the picture, like that :





So, at the moment, we don't say that color blindmen are BLIND. But they are just have minority different filter.

Left Or Right Handled Are You

I'm get a test from http://www.lefthandersday.com/tour3.html. The content of the page are the test of Left Handled. Please look this picture (Fig 1):

Fig 1.

Please answer the question: Which Hand Side at the pictures are use? Right or Left?


If you can answer all pictures under 20 second, you have a potential to use LEFT handled. The Left Handled human have a brainskill to determine, which is hand use. Please continue with second Fig

Fig 2.

Which Triangle you see at the picture? One triangle is BLACK Line, and other Triangle are white. If you see the dominant white triangle, you have Right Brain or LEFT Handled.


So, you can try the exercises below that I get from http://www.lefthandersday.com/tour3.html.

We all, of course, know in which hand we hold a pen, but how far does this bias extend throughout your body? Are you left-eared? Left eyed? Here is a simple test you can apply to yourself.

1. Imagine the centre of your back is itching. Which hand do you scratch it with?
2. Interlock your fingers. Which thumb is uppermost?
3. Imagine you are applauding. Start clapping your hands. Which hand is uppermost?
4. Wink at an imaginary friend straight in front of you. Which eye does the winking?
5. Put your hands behind your back, one holding the other. Which hand is doing the holding?
6. Someone in front of you is shouting but you cannot hear the words. Cup your ear to hear better. Which ear do you cup?
7. Count to three on your fingers, using the forefinger of the other hand. Which forefinger do you use?
8. Tilt your head over on to one shoulder. Which shoulder does it touch?
9. Fixate a small distant object with your eyes and point directly at it with your forefinger. Now close one eye. Now change eyes. Which eye was open when the fingertip remained in line with the small object? (When the other eye, the non-dominant one, is open and the dominant eye is closed, the finger will appear to move to one side of the object.)
10. Fold your arms. Which forearm is uppermost?

If you have always considered yourself to be right or left-handed you will probably now have discovered that your body is less than total in its devotion to its favoured side. If you are right-handed the chances are that you were not able to be 'right' 10 times.

Decimals to Binary with natural Calculator

If you have many problems to count the equivalent of Decimal and Binary number, you can use the binary and hexadecimals calculator. But, if you don't have it, you can use this way. The pictures are get from http://www.arvindguptatoys.com/toys/fingervalue.html.

The art of decimals

If you remember with my other post about the number. We can look at the formula like this:

1. (1/4)¹ + (1/4)² + (1/4)³ + (1/4)⁴ + (1/4)⁵ + . . . . = (1/4)+(1/16)+(1/64)+(1/256)+… ≈ 1/3

   

2. (1/3)¹ + (1/3)² + (1/3)³ + (1/3)⁴ + (1/3)⁵ + . . . . = (1/3)+(1/9)+(1/27)+(1/81)+… ≈ 1/2
   
3. (1/2)¹ + (1/2)² + (1/2)³ + (1/2)⁴ + (1/2)⁵ + . . . . = (1/2)+(1/4)+(1/8)+(1/16)+… ≈ 1/1 ≈ 1
   

So, how about the Art of Math? So Beautiful?? enjoy your day

This Math Exercises, please don't try this at home

Do you ever see the number operation like that? You will see that the result are TRUE with the Wrong way.. Oh shit, don't try this to the other number. OK? hahhahaaa




Please call your teacher to solving the problems!! So, this is some guarantee that your teacher will come to HEADACHE

The circle and the rectangular

Please see at the two pics above. This picture are courtesy from http://bimosaurus.wordpress.com/2010/04/29/lingkaran-dan-persegi-panjang/ . At the first picture show that the circle will be cut as eight pieces congruency. And the part of pieces A and B will assembled as the picture. So we can see that the assembled side will looked like RHOMBUS.

At the Pict 2 we will cut the circle many pieces, nd will assembled as the picture. We can see that the space will look like rectangular space. So, we can determine the formula of rectangular from the circle formula. If the large of circle is (22/7).(r^2), so we can count the wide of "rectangular". Wide = large/r.
