S&S vs. SF in BotNS

This is the message as the crawl holds it, before anything here touched it. What the conversation shows has been through ingest: transfer encodings decoded, attachments dropped, quote markers repaired, and the archiver’s ? resolved into quotation marks and dashes. Those repairs are judgements and some of them are wrong, which is what this page is for. Email addresses are obscured here as they are everywhere else on the site, so it is before our repairs rather than byte for byte.

Do you believe any images that you see on television are truly 
representative? They also require many intermediate steps and 
manipulation via mathematical formulas and electromagnetic physics to 
relate them to the scene observed by those present.

Can you name an instrument that produces a photograph that you agree is 
truly re3presentational?
