Wolfram Tones

I have found this thing from the guy who view and leave comment at this blog. This cool thing name is Wolfram Tones. This is a tool that used to generate the unique style musics. You can generate your own musics at Wolfram Tones' site. This is my own musics ->

Click at the image to play the music.

The wolfram Tones are generated from the Mathematica algorithms. (Follow this link to see how it work) And Mathematica is also my favorite computational tool.

You can generate your own musics and save it to your computer. Is it cool ?
Don't forget to generate your own musics.

Statistical Mechanics Text Book - Free !!!

Today, I have found this cool book available from the author's site.

This is the link -> http://www.physics.cornell.edu/sethna/StatMech/
Let's check it as fast as possible !!! Don't forget to check another resources from this site. Because this site has another cool stuffs such as Java Applet, and Lecture notes.

Flag waving 3D Improved and Source Code

I have improve the equations, and add some features. This is it - >

I use some calculus and linear interpolation knowledge in this applet. This is source code

This is the source file (230.7 kB)

Feel free to use it.

Free Materials on Computational Physics using C++

Today I plan to start reading computational physics. Before I start, I have looked around for the materials. Surely, internet still be my best book store (Free book store). In a short time, I found a lot of cool materails. (I use google search.) And the best that I found is this free book
http://www.physics.ohio-state.edu/~ntg/780/readings/hjorth-jensen_notes2005.pdf
This is a computational physics book (using Fortran and C++). The author is M. Hjorth-Jensen.

If you interest in this field, these link may be (I can say "will be" not "may be") helpful.

My favorite picture from M. Hjorth-Jensen's book

But if you are a newbie, and don't have any programming experience. I would like to introduce you to start with Python, because "Python is a modern object oriented programming language which is freely available. Python has a short learning curve and with the specified modules has powerful facilities for numerical calculation and visualisation." (from http://www.phy.uct.ac.za/courses/phy321f/compphy.htm)
All of these links will be helpful.

And I have one more nice material which I forget it for now. I promise, I will find it and tell you soon.

Funny Science Shows from Steve Spangler

If you want to encourage your students or your children to think that science is fun (not a boring stuff), I would like to introduce this website http://www.stevespanglerscience.com/video/.

Steve have done many interesting show, and you can do some of them at home.

By the way, this may be helpful when you have to do some shows at the party.

This is one of my favorite show.

Have a funny science time!!! +_+

Harmonograph (I have told you, how beautiful physics are.)

Harmonograph is a tool that used to create a beautiful pattern. The principle behide this tool is simple harmonic motion.

In this applet, you can change 8 parameters. By changing these 8 parameters, you can create a lot of beautiful patterns. Don't forget to show me your works.

Click at the image to view the applet.

If your screen is too small to view full size click here -_-
You can see the real harmonograph at this site.

This is not the most beautiful picture. You can see all of my experiments at

If you want source code, I can post for you. Just tell me (as a comment).

Free Vibration of a Linear Triatomic Molecule

Free vibration of a linear triatomic molecule can be easy approximated use mass-spring model.
Each atom is replaced by mass, and chemical bond replaced by spring.

This work tells you that all of vibration style can be explained by linear combination of normal mode.

You can change the amplitude of each normal mode by sliding the sliderbars.
