The Higher Education Bubble

When will it pop?

He makes a point that doesn’t get made enough — that what kind of degree you get matters, but a lot of these children (and particularly the ones who are shifting back and forth between occupying Wall Street and occupying their parents’ basements) don’t get that. Nor does the student loan program.

In defense of classical studies.

Propellant Depots

Over at Aviation Week, Frank Morring says the NASA studies continue:

Michael Gazarik, NASA’s space technology program director, says that CPST and the Space Launch System (SLS) heavy-lift rocket currently under development are complementary technologies. “To explore deep space we need a heavy-lift vehicle — SLS — and we need this technology. We need to be able to demonstrate how to handle cryogenic fluids in space.”

He has to say that. It’s literally politically incorrect to say anything else, and will be until SLS dies. But the reality is that propellant storage on orbit is essential to spacefaring. Heavy lift is not.

And…the empire strikes back. A piece defending SLS/BMR by Mike Griffin and Scott Pace, over at Space News. Will I have a response? You bet. Stay tuned.

Here is one point (though there are others) that I will really pound on:

The challenge for fuel depots is simply that the marginal specific cost of payload to orbit is generally lower for larger launch vehicles. There may be exceptions, but the trend is clear.

There are at least two avenues of attack. What mine will be is left as an exercise to the students. Oh, and initial link fixed. Sorry.

[Late evening update]

Clark Lindsey has started to rebut, and it’s a good start. But there are a lot more fish in that barrel…

An Open Letter To Greg Mankiw

In which oversized children at Harvard demand that they be mistaught economics. I love the comment from “Karl Marx.”

The Crimson‘s response is brutal:

…the students’ attempt to connect their classroom protestations to the Occupy movement illustrates the disjointed and often unfocused nature of the movement. Indeed, it seems ironic that students in an introductory economics course at Harvard feel that by walking out of their completely optional lecture taught by a famous economist on the theme of income inequality feel that their actions ought to be considered a sign of solidarity with the Occupy movement. Such protests don’t show solidarity, they show ignorance and a lack of self-awareness.

There’s a lot of that going around at #OWS.

More Guns Found In Arizona

And the Pinal County Sheriff isn’t happy:

While Sheriff Babeu and his deputies are doing their best to fight these cartels with limited resources, the Obama Justice Department has been arming the enemy with weapons Babeu’s deputies don’t even have.

“Outrage and betrayal. This has never happened before in the history of our country. We may have given armaments and weapons to our allies who may have later become our enemy, but we’ve never given them directly to our enemy,” Babeu said when asked about his initial reaction to Operation Fast and Furious.

“These are the most violent criminals in North America and we facilitated and gave weapons, weapons that my deputies don’t even have, to these cartels,” he said. “It’s more than insane, it is horrific to think that our own government did this.”

Elections have consequences.
