When is an Asteroid Not an Asteroid?

When is an asteroid not an asteroid?

The layered structure of Vesta (core, mantle and crust) is the key trait that makes Vesta more like planets such as Earth, Venus and Mars than the other asteroids, McCord said. Like the planets, Vesta had sufficient radioactive material inside when it coalesced, releasing heat that melted rock and enabled lighter layers to float to the outside. Scientists call this process differentiation.

This question immediately demonstrates once again the terrible mess the International Astronautical Union made when it decided several years ago to define what makes a planet, and came up with a definition that simply doesn’t work. For if Vesta should be considered a planet, why not Pluto?

University Protects Student Who Issued Jihadist Death Threats Against Conservatives and Jews

More craziness: McGill University has decided to protect the student who issued jihadist death threats against conservatives and Jews.

Some examples of the student’s threats: “I want to shoot everyone in this room,” followed by “I should have brought an M16.”

Here is McGill’s interpretation: “We have come to the conclusion that the messages don’t constitute a threat to the community.”

“Worldwide-temperature increase has not produced acceleration of global sea level over the past 100 years”

From Watts Up With That: New sea level data shows that there has been “no acceleration of global sea level over the past 100 years,” despite the increase in temperatures. Key quote from the paper:

It is essential that investigations continue to address why this worldwide-temperature increase has not produced acceleration of global sea level over the past 100 years, and indeed why global sea level has possibly decelerated for at least the last 80 years.

The incremental approach is working

He has a point: Fred Barnes argues that the Republican incremental approach to cutting the budget makes sense politically. Key quote:

The end zone is far away, however, and impatience won’t get Republicans there. Impatience is not a strategy. It may lead to a government shutdown with unknown results. To enact the sweeping cuts they desire, Republicans must hold the House and capture the Senate and White House in the 2012 election. Then they’ll control Washington. Now they don’t.
