The Man, the Myth ...
Dacoda Bizmark Nelson is a 0 year old graduate of The College of New Jersey in Ewing, NJ. His B.Sc. was awarded for the study of physics and he will soon (read: eventually) attend graduate school in order to obtain a PhD in high-energy physics unless he finds that a career outside of academia suits him. Dacoda edits Wikipedia in his somewhat tenuous free time because it's something fun to do and it's a great way to give back to a project that has been such an indispensable source of information over the years.

His favorite equation is:
 * $$R_{\mu \nu} - {1 \over 2}g_{\mu \nu}\,R + g_{\mu \nu} \Lambda = {8 \pi G \over c^4} T_{\mu \nu}$$

because not only is it æsthetically pleasing, but it's also pretty useful. Aside from describing a four-dimensional 'fluid' analogizing the motion of the universe on a grand scale, it reduces in the weak-field limit to a simple expression of the Newtonian gravitational potential and is -- more importantly -- a pretty good description of the flow of traffic on a highway populated with bad drivers.

His second favorite equation is a series of equations called Maxwell's Equations. Of course, they're actually 4 other people's equations with minor adjustments, but Nelson finds it interesting that the connections hadn't been clear to begin with. It seems that sometimes the hardest discoveries are the ones that seem stupidly obvious afterwards which is kind of an amusing fact.

Dacoda is still getting used to what it is to edit Wikipedia, having his first created page disappear in the course of several hours. This was, however, not an oversight but in fact a justifiable deletion: the page was tripe. After a bit of homework Dacoda rewrote the page and submitted it a second time. Dacoda edits Wikipedia simply because it feels a lot like working for the Hitchhiker's Guide.

Dacoda is highly interested in the mathematical side of physics as well as terrestrial applications for astrophysics. His hobbies include data analysis, robotics, and programming. Dacoda also has a burgeoning interest in the English language and dabbles occasionally in philosophy. Mostly though, he just loves mathematics and computers so anything that combines the two is right up his metaphorical alley.

A Thing Which Absolutely Nobody Asked For
You're probably curious as to what those final equations look like so here they are, in differential and integral form, so please enjoy yourself; Nelson knows he always does.

PGP Key
In the event that one ever wishes to whisper lovingly into my ear via port 25 (that sentence is mostly borrowed from a certain famous computer scientist) you'll probably want to know this. More specifically, if you're a huge nerd or computer scientist you'll appreciate this section - if you're not then c'est la vie.

Online Presence
Nelson maintains a somewhat copious online presence as a result of sitting in front of a computer for long hours at a time trying to figure out how the hell to get Mathematica to solve the massive problem he's been assigned so that he can double-check it against the solution he came to over several more hours without a computer ignoring his friends and scribbling. In all reality it's not actually a difficult assignment, Nelson just isn't entirely fluent in the language of the machines yet. Also he likes to quadruple-check his solutions; first without assistance, then with a TI-89 Titanium, then again without assistance, and finally with a probably over-elaborate and highly inelegant Mathematica notebook.

Nevertheless, there are several sites that may or may not be of interest - none owned but all maintained (at unusual intervals) by Dacoda Nelson himself, which would do well in explaining their lack of polish and relevant information.

Personal Web Search Engine
Recent Edit: After moving back to the West Coast (against his will), Nelson has gotten a lot of new networking hardware and a new ISP which likes to make opening ports to public addresses really difficult, so the server is down. He apologizes to those one or two people who connected over the last year but he hopes to get it back up when he has the time.

Nelson, being slightly odd and having a knowledge of computer technology and open-source projects that toes the line between idiosyncratic and downright insane, stumbled across an application called YaCy and got moderately excited. He immediately installed the wonderful application and has since been indexing the web and sharing that index with thousands of other users doing the same thing across the world.

If you're interested, you can click the following linkor go to (websearch.twilightparadox.com). You'll be routed through to his home network briefly to load the search portal's webpage where you can put in a search for anything - just like you'd do with Google, Bing, Yahoo, Ask, or any other search engine. His computer will then go ahead and search its knowledge of the internet for your request and ask that other computers running YaCy do the same. Once it's built up a reasonable number of responses (usually less than 1 second) you'll get back a list of webpages that his computer (and the YaCy collective) think are relevant to your search terms.

He's probably more excited about running the application and the small web server than he really ought to be but c'est la vie. Not to mention the fact that his ISP is doing just about everything in its power to make hosting the server in a reliable manner virtually impossible.

Acknowledgements
Thank you so very much to the wonderful people who allowed me to use their equations as well as the people who authored the articles for Wikipedia I've linked to here. Although, in all honesty, the former are all regrettably dead and the latter are very probably at least a little narcissistic.
