The OG Paper Form

"A form is a document with spaces (also named fields or placeholders) in which to write or select, for a series of documents with similar contents. [...] Forms have existed for a significant amount of time, with historians of law having discovered preprinted legal forms from the early 19th century that greatly simplified the task of drafting complaints and various other legal pleadings."

Typewriter Conventions

"Most forms ask questions. But to save words and therefore save space, the questions usually aren't written out. Instead of asking. "What is your age?" is is better simply to say "Age". [...] The visibility of captions in the upper corner of boxes permits the typist to read them without rolling the typewriter platen up and down as is required when the captions are below the line."

"At the end of the 1800s Herman Hollerith invented the recording of data on a medium that could then be read by a machine, developing punched card data processing technology for the 1890 U.S. census. [...]  Printing could include having fields named and marked by vertical lines, logos, and more"

[...] The Web will be understood not as screenfuls of text and graphics but as a transport mechanism, the ether through which interactivity happens."

AJAX

Definition

"Ajax (also AJAX /ˈeɪdʒæks/; short for "Asynchronous JavaScript and XML") is a set of web development techniques using many web technologies on the client side to create asynchronous web applications. With Ajax, web applications can send and retrieve data from a server asynchronously (in the background) without interfering with the display and behaviour of the existing page."

Forms that are not Forms

Mozilla Developer Network
A Form is Not Always a Form

"Standard HTML form submission, as described in the previous article, loads the URL where the data was sent, which means the browser window navigates with a full page load. Avoiding a full page load can provide a smoother experience by avoiding network lag, and possible visual issues like flickering. Many modern UIs only use HTML forms to collect input from the user, and not for data submission."

Ship of Theseus

"It is supposed that the famous ship sailed by the hero Theseus in a great battle was kept in a harbor as a museum piece, and as the years went by some of the wooden parts began to rot and were replaced by new ones; then, after a century or so, every part had been replaced. The question then is if the "restored" ship is still the same object as the original."

"And this may work for radio buttons and checkboxes, but what if there were text boxes that could be used to enter a price range? When would users expect the form to submit? Submitting while typing is out of the question. This leaves submitting the form on blur (tabbing or clicking out of the field), which is odd and unintuitive."
