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!!

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.

The Other Art of Number

Please check and think about the numbers below. There is some *arts* to make the mathematics are beautiful. The limits of quarter whit exponential 1 and etc, will reach 1/3. 1/3 will reach 1/2, 1/2 will reach 1/1. So, Please note it whit th

  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

The Error Number

Now, I will share to you about something that will happened in Mathematics. Please see and think about it:

x = 0,9999999
10x = 9,999999
10x – x = 9,999999 – 0,9999999
9x = 9
x = 9/9
x = 1

Now, We will know.. That the after point decimals are DANGEROUS to neglect it.. So, please rethink about your DECIMALS Approach to make some match result!!

The melting of the World

I have a magic.. Yes, when you see this picture below, I will be the magician. You can see that I will make all of the world will melting. So, follow our instruction:



  • Please See the Running circle below

  • Please deep in see, concentrate with the middle point of circle

  • Please, feel the deep.. deep, and you will fly..Still in focus to the middle of circle 20 second, 30 second, and

  • Please, wake up, and see all of the surface near you.. It will be melting.. MELTING
