I'm a mathematician working in algebra. I've been using TeX since 1987, but couldn't write my Ph.D. thesis with it. Sob!

I teach LaTeX at my university, besides the mathematics courses. I'm the author of some LaTeX packages and even of one Plain TeX package. At my site it's possible to download my book on LaTeX programming (in Italian, sorry).

Here's my motto for TeX.SX:

Pronto prontissimo son come il fulmine: sono il factotum della città. (From "Il barbiere di Siviglia", music by Gioachino Rossini, libretto by Cesare Sterbini.)

@entne I am very sorry for your thesis. :( You can always typeset a different version for your enjoyment using a real class. ;-)

comment How to switch between horizontal and vertical modes?
Sorry, but without seeing the code it's impossible to say more. But \vadjust is for adding vertical material when we're in horizontal mode, so I can't understand why you need to use it in the first place. However, the way to ensure being in horizontal mode (which starts a paragraph, if issued in vertical mode) is \leavevmode.

comment How to switch between horizontal and vertical modes?
You don't want to switch to horizontal mode in order to use \vadjust; just say \ifvmode<...>\else\vadjust{<...>}\fi.

comment Using end-of-line delimiter in plain Tex macro
LaTeX uses a different model than Plain TeX which is more “liberal”. While delimited arguments are useful, using them in documents forces to use a very rigid typing style (you can check the source of the TeXbook to see what I mean). Delimiting by end-of-line should be reserved to special situations such as verbatim modes.

comment Using end-of-line delimiter in plain Tex macro
Welcome to TeX.SX! I would recommend against doing this. It requires changing the category code of ^^M and this opens more problems than it can solve.

comment abstract appears in mactex but not in texlive for achemso package
This question appears to be off-topic because it is about a problem due to an outdated TeX distribution

comment Is there a \bigcdot symbol in LaTeX
I don't think \cdot is a good symbol, because it's normally used for multiplication and so it can be ambiguous. There is \odot which has also \bigodot.

I suspect that the machine where the thing doesn't work has an outdated TeX distribution; probably a TeX Live/Debian 2009. The only way out is to upgrade it.

@ManuelSelva No, there's no automatic way. I feel that good indentation helps in reading the code, so I took the liberty to fix some of the spacings

Welcome to TeX.SX! You can add images; use the interface and remove the ! in front of the link. A user with suitable privileges will reinsert it.

comment Correctly typesetting a relation
Adding \; would still leave < considered as a binary relation symbol; if it comes first in a formula, no problem, but if it's not the first object …

comment Correctly typesetting a relation
The normal definition of \mathalpha is \relax; it's actually simply a place holder. Your code works because of the braces around <.

comment Correctly typesetting a relation
@rainer This one is the correct answer; Jagath's one has better explanations of what's going on, though. No space is inserted between consecutive relation symbols, which are treated like a single one.

comment Correctly typesetting a relation
The diagnosis is correct, but the cure is wrong: \mathalpha is not the correct command, which is \mathord (or just a pair of braces around <).
