A Tribute to Einstein

Sunday, October 16th, 2005 -- By ET

I’m always fascinated by Einstein’s life.  I have created a random quote function for this blog on the sidebar with 99.9% of the quotes from Einstein.  Last Tuesday, PBS’ NOVA premiered a program called "Einstein’s Big Idea".  Although having a presentation last Wednesday, I nonetheless sat for two hours to watch that program talking about the elements of Einstein’s famouse quation: E = mc2.  Accompanying that program, PBS has dedicated a site to Einstein

The one quote I like about Einstein is that "I just don’t understant why there is no one understands me, but it seems everyone likes me." 

In 1905, Einstein was a patent officer.  He did not get an academic job because he did not do well in courses other than Math and Physics, and could not get good recommendation letters.  But this is a miracle year:

  • In 1905, Einstein is 26, working on physics on his own. After hours, he creates the special theory of relativity, in which he demonstrates that measurements of time and distance vary systematically as anything moves relative to anything else. Which means that Newton was wrong. Space and time are not absolute, and the relativistic universe we inhabit is not the one Newton "discovered."

That’s pretty good, but one idea, however spectacular, does not make a demigod. But now add the rest of what Einstein did in 1905:

  • In March, Einstein creates the quantum theory of light, the idea that light exists as tiny packets, or particles, that we now call photons. Alongside Max Planck’s work on quanta of heat, and Niels Bohr’s later work on quanta of matter, Einstein’s work anchors the most shocking idea in 20th-century physics: we live in a quantum universe, one built out of tiny, discrete chunks of energy and matter.

  • Next, in April and May, Einstein publishes two papers. In one he invents a new method of counting and determining the size of the atoms or molecules in a given space, and in the other he explains the phenomenon of Brownian motion. The net result is a proof that atoms actually exist—still an issue at that time—and the end to a millennia-old debate on the fundamental nature of the chemical elements.

  • And then, in June, Einstein completes special relativity, which adds a twist to the story: Einstein’s March paper treated light as particles, but special relativity sees light as a continuous field of waves. Alice’s Red Queen can accept many impossible things before breakfast, but it takes a supremely confident mind to do so. Einstein, age 26, sees light as wave and particle, picking the attribute he needs to confront each problem in turn. Now that’s tough.

  • And, of course, Einstein isn’t finished. Later in 1905 comes an extension of special relativity in which Einstein proves that energy and matter are linked in the most famous relationship in physics: E = mc2. (The energy content of a body is equal to the mass of the body times the speed of light squared.) At first, even Einstein does not grasp the full implications of his formula, but even then he suggests that the heat produced by radium could mark the conversion of tiny amounts of the mass of the radium salts into energy.

 I found the following Webring sites quite interesting:

 KryssTal : It’s Relative
A brief introductory account of the Theory of Relativity. This essay uses very little mathematics.

 Muse Astronomy Hobby Page
We have a few Hubble pictures and some astronomy related links you might can use.

 Russell_Einstein Bookstore

 Measuring time and other spatio-temporal quantities
Einstein could not, but with a space-time odometer in addition to a light-clock we can now measure time and spatial distance in the common sense.

 The Dummies’ Guide to Special Relativity
An elementary presentation of Special Relativity for anyone who has successfully completed the 6th grade.

some new functions in this blog

Sunday, October 16th, 2005 -- By ET

It is extremely easy to add plugins to my blog engine: WordPress.

I feel guilty if don’t do it once in a while.  Recently, I added a few new functions.

1. Subscribe to my blog 

After you sign up, each time I post a new entry in this blog, you will be notified by email. 

2. Subscribe to the comments 

In the comment interface, you can select to subscribe to the comment thread, so each time someone adds a comment to this entry, you will be notified.

3. Weather in Cambridge on the side bar

4. Quote du jour

Each time you reload the blog page, you will get a new random quote on the sidebar.  If you come to my blog frequently, you will find that almost exclusively, the quotes are from Albert Einstein. :-)

 

 

 

 

art work on computer chip

Sunday, October 16th, 2005 -- By ET

From CNET :
More than 10 years ago, Michael Davidson went looking to capture the beauty of microchip circuitry in photographs. In among the transistors and wire traces, he found something unexpected: Waldo.

What he found was that in many chips, you can find cartoon characters or hidden texts with a microscope.

I found it quite interesting to browse through  these pictures.  It’s like the famous painters who leave a cursory signature at some corner of their master pieces, only in this case, they did it with special circuit design.  I’ll hide some text in my next paper then.  Look at the first characters of some paragraph, you might find some interesting. :-)

Next time when I write a paper
