I have been attempting to get a very concise and simple 2 page paper on the Fourier transform uploaded to the arxiv. First, I established electronically that I appeared to have posting rights only to the physics arxiv. Since I thought that hep-th might be more appropriate, I requested an endorsement from 2 people last week. One has yet to reply but the other, a highly respected professional theoretical physicist from the northern hemisphere, replied very promptly and sent an email to the arxiv that same day confirming his wish to act as my endorser.

Alas, the arxiv rules now require that endorsers be active users of hep-th, so my potential endorser was sent an email explaining that he wasn’t qualified to endorse for hep-th. If anyone who is qualified to endorse for hep-th would like to take up this case, it would be greatly appreciated. Anyway, people brilliant enough to spell my name correctly may obtain a copy of the paper here.

Do you still have submission privileges in math.QA and gr-qc?

Nope, a search for either of your names doesn’t turn up a paper by you (I spelled them correctly).

What did I do wrong?

I have noticed that electrical engineers tend to deal with Fourier Transform Pairs [FTP]:

The Scientist and Engineer’s Guide to Digital Signal Processing

By Steven W Smith, PhD

Chapter 11: Fourier Transform Pairs

“For every time domain waveform there is a corresponding frequency domain waveform, and vice versa. For example, a rectangular pulse in the time domain coincides with a sinc function [i.e., sin(x)/x] in the frequency domain. Duality provides that the reverse is also true; a rectangular pulse in the frequency domain matches a sinc function in the time domain. Waveforms that correspond to each other in this manner are called Fourier transform pairs. Several common pairs are presented in this chapter.”

ch11.htm

Both theoretical mathematicians and many physicists appear to ignore these FTP pairs.

Yet there are both 1) Time Dependent and 2) Time Independent versions of the Schrodinger Equation that appear to be consistent with Fourier Transform Pairs?

To those who can’t find the paper – you have to use the sciprint search engine, not the search box on the front page.

That was quite mind-expanding. I hadn’t read Carl’s stuff before. So he has this algebra in which the particle masses show up as quantum numbers, and you want to apply the inverse of Kapranov’s map to it, and recover the whole Standard Model – is that a fair summary?

As we have unfortunately seen, arxiv is no longer the free repository it was intended to be. There is no good reason why Kea should not be able to post. Mediocrity can be good for careers, and the place is crowded with papers on strings, branes and “dark energy.”

Proponents of these speculations claim to be secular, but follow their strings, branes etc. with religious fervour. I hope to see your paper soon, perhaps we will do one together sometime.

It’s good to hear from everyone. Thanks.

…and recover the whole Standard Model – is that a fair summary?Just the standard model? No, no. The standard model cannot explain the particle masses. We want to do Quantum Gravity.

The more the Cornell arXiv succeeds in guarding its content from outsider contamination,

the more its insiders isolate themselves from the new ideas that will lead to understanding how physics really works,

so,

the Princes of the ArXiv are sealing their own doom to that most terrible fate: being irrelevant.

Back in the 1950s the comic strip Pogo (set in Georgia’s Okefenokee Swamp) was popular. Here is a modified version of a Pogo poem originally entitled “The Prince of Pompadoodle’:

The Princes of the ArXiv

The Princes of the ArXiv

lived behind a castle wall,

behind a moat, behind a guard

of twenty soldiers tall.

The Princes of the ArXiv

were the safest men they say …

They sat alone, safe, locked alive,

to count another day.

The Princes of the ArXiv

may hoard each empty hour,

but so what ? No predictions come from

the silent stony tower.

Tony Smith

PS – As to doug’s comment about “Fourier Transform Pairs”,

it seems to me that the duality is pretty much the position space / momentum space duality,

which has a nice interpretation in Clifford Algebra physics, as shown by Dennis Marks has shown in 2003 paper “A Binary Index Notation for Clifford Algebras” where he said:

“… Complementarity between space-time and momentum-energy is achieved by bit inversion, which interconverts between position representation and momentum representation. Treating momentum as a Clifford covector has the virtue of automatically enforcing the Heisenberg commutation relation as a consequence of the commutation and anti-commutation propeerties of the Clifford elements. …”.

Tony, that’s an interesting comment on covectors and the Fourier transform and I will think about it more. My interests have been in internal symmetries and I have largely avoided learning about Clifford algebra and Fourier transforms.

I look forward to you starting a blog of your own.

And Kea, is there some rule that says that you can’t give us a link to your paper? Making people suffer through searching on sciprint seems to me a way of reducing readership.

## Kea said,

November 5, 2007 @ 9:27 pm

Carl, I don’t have anywhere else to put the paper. One day I will buy myself a cute domain name, but at present I’m still on a tight budget. Besides, I’m sure we’re all smart enough to figure out how sciprint works – eventually.

Kneemo, of course I can. But it can be uploaded here to blogger as well as anywhere else. Nope, Blogger won’t let you upload things like that…

However, at WordPress, you can. Let me see. (sound of typing, manly grunts) Sure enough this is it!

I should also mention that WordPress allows you to import content from another blog, if you’re thinking of switching over. So moving over there is pretty painless. PDF files can be uploaded because they are a form of image file.

Of course things might not be as simple as I guess. It could be that you can only upload pdf files if you pay for the extra thingy that lets me put my hardhat picture up. But I suspect that a free account at WordPress can host pdf files.

And by the way, the next time you release it, please put it in pdf form so I don’t have to. PostScript is somewhat painful to deal with for me, and the TeX programs I’ve worked with put out acrobat just as easily as postscript. And I won’t have to go through this horrible anti spam kluge.

## Kea said,

I don’t want to use postscript, but my latex editor has problems generating pdf and I don’t have the ps-pdf converter. There is a free trial at Adobe, but only for 5 files and I now only have 1 free conversion left, which I’m keeping for my thesis. Thanks for the upload, Carl! This is a good motivation for setting up a WordPress blog.

There’s a free PDF converter program downloadable at http://www.cutepdf.com which I use as a print engine. It seems to work fairly well overall although it does sometimes miss out certain types of image files.
