Lorentz Transformation - A very Brief Derivation

Hi,

Here I give a very brief derivation of Lorentz Transformation.

Lorentz Transformation, Relativity  

 

Today is Pi day and Einstein's birthday, again!

Google's logo is very cute today !  

Today is defined as Pi day, it is also Albert Einstein's birthday. Besides, today is Japaness lover's "white day".

According to Wiki, "In the 1980s the Japanese National Confectionery Industry Association launched a successful campaign to make March 14 a "reply day", where men are expected to return the favour to those who gave them chocolates on Valentine's Day, calling it White Day for the color of the chocolates being offered."

Abstract

Einstein's birthday, the PI day

The day before yesterday, Mar. 14 (3.14), was a great date, because Albert Einstein was born at the same day 130 years ago.

I and my wife enjoyed a very good holiday that day in Taipei. Most interestingly, we found a vivid statue of Einstein made by Ju Ming, stood still in front of the Chen-Ping (eslite) bookstore.

We took several photos around this statue. Here I share one of them with you.

My Eprint papers

 Hi,

These are my Eprint papers. Some have already been published as Journal papers, some have not.

I will discuss some of them here someday.

You can link to  http://arxiv.org/ and search my name Pi-Gang Luan in Physics [arxive: All], and these papers would be shown to you. There is an exception, my YBE paper ([Colored solutions of Yang-Baxter equation from representations of U_{q}gl(2)] ). In that case you should type [Pi-Gang Luan] instead of Pi-Gang Luan to find the paper.

My Chinese blogs and My Photonic Crystal Book

Hello,

If you can read Chinese, you can visit my Chinese Blogs as follows.

Besides, I and my colleague (Prof. chen) published a Photonic Crystal book: "Photonic Crystals -- From butterfly wings to nanophotonics" in 2005.

This is my first 2009 article

Now I come here again.

From now on I want to share with you my research experiences and personal opinion on  time dependent quantum system, photonic/sonic crystals, and metamaterials.  I would also like to write some articles on science teaching stuff.

I come from Taiwan. Usually I speak chinese, and have no many oppernituties to practice my English, so I wish someone can help me to improve my English. Thanks !

  

 

Here is a good place

Hi,

 It's the first time I visit here. I find here a wonderful place.
