Unfortunately, they will probably look horrible in older browsers, like Netscape 4.x and IE 4.x. Moreover, many posts use MathML, which is, currently only supported in Mozilla. My best suggestion (and you will thank me when surfing an ever-increasing number of sites on the web which have been crafted to use the new standards) is to upgrade to the latest version of your browser. If that's not possible, consider moving to the Standards-compliant and open-source Mozilla browser.

Erdős Number

It transpires that Bill Tozier (Erdős #4) is auctioning on eBay the opportunity co-author a paper with him, and thereby secure the successful bidder an Erdős number of 5. John Quiggin quickly jumped in to offer willing co-authors a free Erdős number of 4.

This got me to thinking. What’s my Erdős number? Can I profit from the opportunities currently flying about the 'net?

After checking the Erdős Number Project, I now know that I have an Erdős number of 4, thanks to three co-authors (Greene, Hubsch and Vafa) I have in common with Shing-Tung Yau (Erdős #2).

No help to be had from Tozier and Quiggin. If I am to improve my Erdős number, I’ll have to do it the old-fashioned way.

Re: Erdös Number

Math Reviews now has a fun facility, “MR Collaboration Distance”, that confirms that your Erdős number is at most 4. The path that it found for you is one that you know,

Distler -> Vafa -> Yau -> Chung -> Erdős.

(Note also that if you are really perfectionist about your markup, “Erdös” is a misspelling of “Erdős”. At least I think that the Hungarian umlaut is the right one.)

Re: Erdös Number

Indeed, you are correct, Greg. Hungarian has a double acute accent, not an umlaut. So it’s ő (ő), not ö (ö).

Live and learn.

And thanks for the tip about the MathSciNet Collaboration Distance tool. Hours of amusement …
