The Evocative Power Of Language
Most philosophical studies of how language functions have focused on semantics - how language conveys meaning. In ordinary speech, language is not confined to the transmission of information. It can be used to evoke strong emotions.

The trick is that the green spiral and the blue spiral are actually the same color of green. You can see this in several ways using PhotoShop. One way is to replace the blue color with black and see that the green stripes go to black too.
The Bookworm And The Encyclopedias - The Solution
Last Monday I posed a simple math puzzle:
A set of 10 encyclopedias is sitting on a bookshelf in left-to-right numerical order.
Each single volume contains 1,000 pages.
A bookworm eats its way directly and linearly through them in a straight line.
It starts on page 1 of volume 1.
It ends on page 1,000 of volume 10.
Question: Not counting any covers, flysheets, etc., how many pages does the bookworm eat ?

No one disturbs his fellow men with a new view unpunished.

Electrical arcs stabbed through the violet dusk. Heated solutions groaned toward their boiling points. Bubbles rose helically through luminous green liquids. Miniature explosions occurred in distant corners of the facility, sending up showers of glass as nearby workers cowered beneath seaside umbrellas set up for just such protection. Gauge needles oscillated feverishly. Sensitive flames sang at different pitches.
First UIUC now NIU and SIU are under investigation for clout, and political influence in admissions.
First the University of Illinois at Urbana Champagne is found to have had a list of students who would get admission as a political favor. Now Northern Illinois University, and Southern Illinois University, are in on the shenanigans as well.
Here in Chicago we have a anecdote that sums up so much of the way the government in the city of Chicago, County of C(r)ook and state of Illinois work. Abner Mikva
