Read the 2nd-to-last paragraph.

"The Earth's rotation is faster at the equator.."

This is why you don't send a fashion reporter to cover science.

Here's another one. Maybe it's a CNN thing:

SoBig.F was first posted to a porn Usenet group," said Jimmy Kuo, research fellow at anti-virus software maker Network Associates Inc. Usenet is a popular forum on the Internet where computer users with similar interests post and read messages.

Humans are inherently stupid. It is my personal belief that all people should have to take a common sense and intelligence test. You need a certain score to fly planes, certain score to drive, and a certain score to so much as leave your home. If you score below a certain number you should have to wear a sign that says "I Am Stupid" just so the rest of us understand their mistake.

I think the surface speed is faster at the equator.

The equatorial radius of the earth is 6378 km and its speed or rotation at the equator is 1670 kilometers/hour with a 24-hour day. At Los Angeles with a latitude of +34 degrees the speed is 1670 x cos(34) = 1384 kilometers/hour.

It would be faster at the equator, it's the same concept as a point on the outside of a record spinning faster than a point near the middle, IMO.

The earth rotates at constant *angular* velocity regardless of location.

However, the *linear* velocity of the ground changes depending on surface location you measure it at.

There are some equations for converting... Yoni probably knows them by heart so pester him for them :P

v = omega * R

v is the linear velocity (meters per second), omega (written in lowercase, looks like a 'w' with round corners) is the angular velocity (radians per second, or Hertz), and R is the radius, i.e. the distance from the center of the Earth (meters, or m).

The Earth's rotation maintains a constant angular velocity (or at least, I think it does...!). The linear velocity depends on the distance from the center of the Earth as the above formula shows - this distance may vary depending on whether you're at the Dead Sea or on Mount Everest.

Physics at high school paid off. I have one more year remaining so I can learn electricity stuff too.

The article said the earth's ROTATION is faster at the equator. Rotation is measured in angular velocity as someone pointed out.
