comment Do I need to create my images at twice the pixel dimensions on a retina display?
If the question is "does having a retina display on a system imply that Photoshop tells me my image is 20x20 when it is really 40x40", I think the answer is "no."

comment What exactly is a “Pixel”?
I think my link confirms what you say except it seems your definition of "average" is what they call "superior"

comment What exactly is a “Pixel”?
I was curious about the visual acuity statement. At 50cm (about 20inches), the smallest black line/white line pattern a person with "superior vision" can distinguish is approximately 100 micrometers (the width of a human hair). 300dpi has an approximate dot spacing of 85 micrometers.

two monitors, both 1080p (1920px by 1080px native) resolution. One is 13 inches (diagonal), one is 40 inches. How can either one be 72ppi? 100ppi?

I didn't downvote, but I suspect it is because the full content of you answer is in a link to another website. If you can summarize you'd have a good answer.

@AmeliaBR: I think it is important information, the OP is asking from a position of naive ignorance and there are so many facets to the issue, especially when trying to pick up the information informally.

"try drawing the MonaLisa with only 9 blocks of one solid colors" we did this in art school with casein.

comment What's the best way to reproduce a Captcha distortion?
In addition to the answers provided, captcha/recaptcha are libraries for server software. You could easily install a local web server package ("WAMP"/"LAMP") and generate your own using the actual captcha software.

What about the "default" all-white locked background layer? Hide/delete it?

comment What does 8 bit alpha (PNG) mean?
@terri: It is important to check the pixel specs in the link in Scott's answer. "72ppi" does not make sense as a specification and it does not appear anywhere on that specification page. Ignore "ppi" and "dpi" and focus on actual pixel dimensions.

comment Is there a series of key principles to design a simple interface for a complex application?
There are some things which are rarely done but when they are, they are done 1000 times (mass data entry etc). Consider this when burying functionality.

comment How do I achieve the equivalent of using small caps in Arabic?
@einpoklum: Eskimos are famous for having lots of words for snow. Unfortunately that is a myth. It is unclear how fluent you are with Arabic, but the question itself implies you may not be highly proficient else an "Arabic Smallcaps" analog would be obvious to you. You should heed the warnings here. The best advice in light of all this is that you should adjust the visual weight of the English text so that it best matches the visual weight of the Hebrew and Arabic. This is, after all, the purpose of Smallcaps in English texts: to get the uppercase to fit within the surrounding context.

comment I wonder if I can get >116 simple linear shapes to use them as a Alphabet?
There are 26 letters in the English alphabet along with the numerals 0-9. If you flip each of these on the vertical and/or horizontal axis, you have a base set of 144. Some of them are symmetrical on one or both axes and some will resemble others, but just on this basis alone, I would say your simple answer is "yes."

comment What is the name of hobby grade equipment to create photos where the background can be easily removed?
I have been in pro studios. Paper, cardboard, and lots of tape are professional grade tools

comment I wonder if I can get >116 simple linear shapes to use them as a Alphabet?
Not sure the math community can help further. You pretty much covered it: 116 shapes does not require a lot of components. However, the key feature of writing is data extraction, not ease of writing so the real challenge (before getting into how one gets a new system adopted) is error correction and recognition/discrimination.

comment How can I create an action that hides or shows layers by a specific name in Photoshop?
activeDocument.artLayers[i].visible = true; you can reference by ("name") or index (1). For the OP's use, one needs to iterate through the whole list (for (i=0;i < docRef.artLayers.length ;i++)) and search for the string inside the layer .name
