Kerry hits bottom in popularity poll
By JOHN CHRISTOFFERSEN , Associated Press Writer NEW HAVEN, Conn. — Massachusetts Sen. John Kerry ranked last in a poll released yesterday that scores the popularity of national leaders.
Americans have the warmest feelings about former New York City Mayor Rudy Giuliani, Republican Sen. John McCain and Democratic Sen. Barack Obama, the poll by Quinnipiac University showed.
The university's "thermometer reading," taken the week after the Nov. 7 election, asked voters to rate their feelings for 20 leaders on a scale of 0 to 100.
Kerry, the 2004 Democratic nominee who was roundly criticized before the election for suggesting that students who don't study could end up stuck in Iraq, came in last at 39.6. Kerry later apologized for what he said was a botched joke.
Giuliani, a Republican weighing a presidential bid in 2008, scored the highest at 64.2. Obama and McCain, who are also considering a 2008 campaign, finished next at 58.8 and 57.7.
Massachusetts Gov. Mitt Romney, who has been laying a foundation for his own presidential run, ranked No. 13, with a rating of 45.9.
President Bush was 15th out of 20 while his secretary of state, Condoleezza Rice, was fourth and former President Clinton fifth.
Connecticut Sen. Joseph Lieberman, who lost the Democratic primary before winning re-election as an independent, ranked sixth with a score of 52.7. New York Sen. Hillary Rodham Clinton scored ninth of the 20 leaders with a score of 49.
Democratic Rep. Nancy Pelosi, in line to become the next House Speaker, improved her standing, moving from last to 12th in a few weeks. The next Senate Majority leader, Democrat Harry Reid, was 19th.
"As we enter the presidential campaign of 2008, Giuliani and McCain are in enviable positions," said Peter Brown, assistant poll director. "They are well-regarded and most Americans are quite familiar with them. Obama's showing is impressive, but four in 10 Americans still don't know enough about him to have an opinion."
The telephone poll was conducted from Nov. 13-19. Quinnipiac surveyed 1,623 registered voters nationwide and the poll has a sampling error margin of plus or minus 2.4 percentage points.

Mobius Strip?




According to Physlink.com - very roughly a surface is orientable if it has two sides so that, for example, is it possible to paint it with two different colours. A sheet of paper or the surface of a sphere are examples of orientable surfaces. A Mobius strip is a non-orientable surface: you can build one with a strip of paper (twist the strip and glue end together to form a ring) and verify that it has only one side: it is not possible to paint it with two colours.


In short a Mobius strip only has one side and one edge.





Ants would be able to walk on the Mobius strip on a single surface indefinitely since there is no edge in the direction of their movement. Just like what M.C. Escher depicted in his famous picture (shown on the right.) Mobius strip was named after the astronomer and mathematician August Ferdinand Möbius (1790-1868). He came up with his 'strip' in September 1858. Independently, German mathematician Johann Benedict Listing (1808-1882) devised the same object in July 1858. Perhaps we should be talking about the Listing strip instead of the Mobius strip.
