The Noble, Objective Scientist

…exists primarily in mythology:

There is deeply ingrained in American culture — particularly nowadays on the Left — the stereotype of the scientist as pure in intent and action, caring only for the Truth, let the chips fall where they may. The scientist works readily with other scientists (except when s/he is working alone, late into the night, thinking deep thoughts), accepts — nay, encourages — challenges to her/his theories and findings, welcomes new information and hypotheses, and is always willing to change his/her mind based on better data, models, and/or reasoning.

It is, to quote the late Douglas Adams, a load of dingos’ kidneys. A very large, steaming, rotting load of dingos’ kidneys.

Particularly when it comes to a politicized field like climate “science.”

StratoLaunch

Here’s an article at the WaPo about it. This isn’t correct, though:

It is always desirable to launch to the east to capi­tal­ize on the direction of the Earth’s spin. The Earth travels about 1,000 mph west to east at the equator; you need to reach a speed of 17,000 mph to get to low-Earth orbit, so there’s no point in penalizing yourself 1,000 mph by heading in the wrong direction.

No, not “always.” Only for low-inclination orbits. For very high inclination, or retrograde, it’s actually preferable to launch from a high latitude (ideally, for a retrograde orbit, you’d like to launch from a pole, to eliminate any earth rotation, because it’s rotating in the wrong direction).

McDonalds Math

This sort of thing is why we don’t want economic illiterates in charge of the economy. Hey, morons. Don’t you think that if McDonalds could just raise their prices (and hence revenues) by 17% (actually 26%), they’d have already done that?

[Update a while later]

Another question:

Let’s say McDonald’s decided to double all its salaries, so that the entry-level wage became $16 an hour instead of $8 an hour. Why would McDonald’s continue to employ their $8 an hour workers when instead they could hire “better” workers who are worth more? (And those of you who think that the skills, linguistic abilities, experience, intelligence, etc. of fast-food workers makes no difference in service don’t eat in McDonald’s much.)

Again, this is why you don’t want people making policy who don’t understand how business works. And this administration (and sadly, Congress, of both parties, but much more so among the Democrats) is full of such people.
