A person who studies art in the most broad sense is an aesthetician. The study of the principles and definition of art is the field of aesthetics. Sometimes, this word is used to include the study of all sensory experience, as derived from nature as well as art. One can say that an art student is "one who studies art" as well, but I think you mean "someone who studies art professionally". This does not mean that an aesthetician cannot also be an artist or that an artist cannot also be an aesthetician. Ayn Rand is a good example of person who was an artist and also an aesthetician. She wrote fiction literature, but also proposed and analyzed aesthetic theories. This is not to be confused with someone who studies the history of art, which is an Art Historian.
Your question doesn't make sense
Please rephrase your question, which doesn't make sense.

It doesn't make much sense. It means I am of/from thou art.
Yes Art and Technology are equivalent. Why? Well here's why. Think about it. To make technology, you need a sense of creativity (art) to begin planning this technology and making it. And to make art, you need to have technological smarts to know how to create the art piece and master it into something wonderful. So there's your answer! :)

Not isn the true sense of the term. Art is something original you create to make a statement for all time. A biological function hardly qualifies as a higher pursuit.
The quote "A sense of humor is part of the art of life" can be found in the book "The Art of Living" by Epictetus, an ancient Greek philosopher.
I disagree with the popular answer of it meaning "why" in this usage. That meaning doesn't make much sense since it was his surname that was the subject of the passage. The word, "wherefore" can also mean "where". This does make sense as she didn't have to go to an open window to make her statement or soliloquy. Her calling out, "Wherefore art thou" meant that she didn't know he was present and it supports her statement "What man art thou, that, thus be-screen'd in night, So stumblest on my counsel?" as he was obscured in the darkness below.
There is not a definition for the phrase time art. Art however, can be considered timeless in a sense that the older the art is the more valuable it becomes.
Your question makes no sense.
