@cristo: Nice link!

Zee may be being poetic, but what about the quote: "Quantum field theory arose out of our need to describe the ephemeral nature of life; which I feel more and more as I get older." If indeed the quote is stated in the same sense as George Jones' explanation, why would the creation and...

In one of Anthony Zee's ASTI lectures (http://www.asti.ac.za/avi/14-Zee-QuantumFieldTheory-2.avi), he comments on this quote. After reciting the quote (3.30 min.), he says: "Which I feel more and more as I get older." Then he recites a Chinese phrase which "describes the nature of life"...

So, "the ephemeral nature of life", here, refers to the observed fact that particles 'are not forever' in some abstract sense. What confuses me about his quote is the possibility that he may be referring to biological "life" in some way.

I'm not sure if this post belongs in this forum; feel free to move it. In his book, 'Quantum field theory in a nutshell', Anthony Zee writes: "Quantum field theory arose out of our need to describe the ephemeral nature of life." What does he mean by this?

If you are familiar with PHP, this tutorial explains how objects are instantiated from a class; it gives a good feel about what role objects play. The tutorial is light-hearted. http://devzone.zend.com/node/view/id/638

Thank you.

What is the total file size for the complete MiKTeX system? The website (http://www.miktex.org/Setup.aspx ) doesn't seem to give this information.

I found a solution to my problem: http://www.techonthenet.com/access/queries/update2_2007.php Thank you.

Nope, not homework. I am new to Access and databases, so I do not understand how to implement SQL code. Are you referring to this: http://www.sqlcommands.net/sql+update/ What is the "update wizard"? Excel allows a "by hand" method for this. By typing a, for example, "Price" in block...

I have two tables that I would like to link in a specific way. Both tables have a field name labelled, for example, "Price". Both also have a field name labelled, for example, "Item type". In the first table, each of my stock items are listed in the "Item type" field, with the corresponding...

On page 36 of "A Course in Modern Mathematical Physics" by Peter Szekeres, the matrix multiplication rule is given, and then an exercise follows immediately after the rule stating: "Prove this formula". Please see...

Homework Statement Prove the formula. Homework Equations Matrix multiplication: (\text{AB})_{i \,j}=\sum _{k=1}^n a_{i \,k}b_{k \,j} The Attempt at a Solution I do not know how to "prove" the formula for arbitrary values of k and n.

If you would like to learn and understand representation theory, linear algebra/matrix theory is essential.

Correction: In post #1, after the first three words, "I would like...", please add, "...to know...".
