s you might know, I am on an extended maternity leave this week.
I am working on the class, though.

I completed the material for the discussion and placed the questions so you guys can work on it.

About Photoshop: You have to scale the image down, and cop it if you want to.
I place this assignment so you guys find a personal way of dealing with images in preparation for your Mid-term.
You will need to use images in both your mid-term and your final project and it would be good that you could scale them down.

If you cannot scale images down you might end with gigantic file sizes in your Powerpoints.

You can go to the lab and work this simple task in Photoshop there. You can also find images over the internet with those exact dimensions. Finally you can miss this assignment. It is not the end of the world.

WORKING MATERIAL.
Those are links to pages in your help-site about Marshall McLuhan.

To familiarize yourself with McLuhan aphorisms:

Presentation on Mc Luhan's terminology. The ideas are related to each other in a very "playful" style, typical of the author.
Think of a puzzle and trying to build families of words. Don't expect it to "make sense" in a traditional way.

Usually an aphorism is a concise statement containing a personal truth or observation cleverly and pithily written.

Aphorism is a brief saying embodying a moral, a concise statement of a principle or precept given in pointed words.

Example:
Hippocrates: Life is short, art is long, opportunity fleeting, experimenting dangerous, reasoning difficult.
Pope: Some praise at morning what they blame at night.
Emerson: Imitation is suicide
Franklin: Lost Time is never Found again.
