The Pilgrims arrive in New England

6:01 pm

An evening pause: Three hundred and ninety one years ago on this day the Pilgrims first sighted the shore of New England. Knowing that they soon would disembark and attempt to create a new society in this New World, they gathered and signed what we today call the Mayflower Compact, what might be called the first ever consciously written social contract in human history.

Having undertaken, for the glory of God, and advancement of the Christian faith, and honor of our King and Country, a voyage to plant the first colony in the northern parts of Virginia, do by these presents solemnly and mutually, in the presence of God, and one of another, covenant and combine our selves together into a civil body politic, for our better ordering and preservation and furtherance of the ends aforesaid; and by virtue hereof to enact, constitute, and frame such just and equal laws, ordinances, acts, constitutions and offices, from time to time, as shall be thought most meet and convenient for the general good of the Colony, unto which we promise all due submission and obedience.

This idea, that society is formed from the consent of its members, still forms the bedrock idea of America. And woe to us if we ever forget it.

The case against SpaceX

9:38 am

The case against SpaceX. From one of the company’s biggest supporters.

Trent Waddington raises many good points, all of which must be considered to have a clear, educated sense of where the future stands for American manned spaceflight. Two quotes:

The goal of SpaceX is human spaceflight, and the greatest repository of knowledge about human spaceflight is NASA. As such, it would appear obvious that getting NASA to help you to fly humans safely is a good idea. The way to do that is with Space Act Agreements. This is what SpaceX did under the COTS program, and later under the CCDev program.. and they got paid for the privilege. As a result, the Dragon spacecraft will soon be fully qualified as safe for human habitation on orbit as it will be berthed to the ISS and have astronauts inside it.

The problem is that NASA is a precocious customer. They know what they want, they think they know even better than you do how to make it, and they feel no guilt about changing their mind halfway through the project. As such, Space Act Agreements just totally grind NASA’s gears. They don’t have enough control. [emphasis in original]

NASA money is like heroin.. once they start taking it, most people find it very hard to stop. There’s a dependence that has grown between NASA and SpaceX, and although it is obviously a love-hate relationship, it’s going to be very hard for SpaceX to let go.. but, inevitably, they must. The current needs of NASA are very different to the long term goals of SpaceX.

And this:

Fundamentally, SpaceX has a shoddy business case which is best described as a house of cards.. that they’re still trying to play poker with.. and there’s dogs at the table, and they’re smoking cigars! Yeah, metaphor.

Read the whole thing. It’s quite good.

Uncertainty rules the day

2:53 pm

The press reports have been unanimous:

Unfortunately, if you read the actual IPCC panel summary report, you find that, though the majority of the press stories accurately describe the report’s worst scenarios and predictions, all of them downplay the most important point of the report, that the uncertainties are gigantic and that the influence of human activity on the increase or decrease of extreme weather for the next few decades will be inconsequential. To quote the report:

Some historical context in discussing the federal debt

8:41 am

Some historical context in discussing the federal debt.

When Bill Clinton was president, the national debt rose by an annual average of $193 billion; when the profligate George W. Bush was in the White House, the yearly debt increases averaged $612 billion. On Obama’s watch, by contrast, the federal debt has been skyrocketing by more than $1.5 trillion per year. It took 40 presidents and nearly two centuries, from George Washington to Ronald Reagan , for the US government to accumulate $1.5 trillion in indebtedness. The 44th president – aided and abetted by Congress – enlarges the federal debt by that amount every 12 months.

light posting

10:58 pm

Please forgive the light posting these past few days. I was down in Atlantic City, New Jersey, giving a speech to a joint meeting of the local AIAA/IEEE chapters (see the appearances list in the column to the right), then was off to Chicago to visit family for the Thanksgiving holidays. Posting will resume in more detail over the next few days.

The CERN experiment that appeared to see faster-than-light neutrinos has repeated its results, except that not everyone on the team agrees

9:37 pm

The uncertainty of science: The CERN experiment that appeared to see faster-than-light neutrinos has repeated its results, except that not everyone on the team agrees.

The new tests, completed 6 November, did away with the statistical analysis by splitting each pulse into bunches just 1- to 2-nanoseconds long, allowing each neutrino detected at Gran Sasso to be tied to a particular bunch produced at CERN. These tests were carried out over 10 days and provided 20 events. The researchers confirmed that the neutrinos arrived 60 nanoseconds early, with an uncertainty of about 10 nanoseconds, comparable to that of the initial result. The collaboration has also checked its original statistical analysis, but today’s decision to submit the results to a journal was not unanimous. “About four people” among the group of around 15 who did not sign the preprint have signed the journal submission, according to a source within the collaboration, while “four new people” have decided not to sign. That leaves the number of dissenters at about 15, compared with about 180 who did sign the journal submission.

Obamacare threatens to cripple the American medical device industry

1:26 am

Repeal it! Obamacare is forcing the American medical device industry out of business.

The 2010 law imposed a crippling 10-year, $20 billion tax on revenues — not on profits — earned by companies that make medical devices, such as catheters, artery-clearing stents, scalpels and pacemakers. The tax is prompting American companies to shed jobs, move factories overseas and reconsider niche-market research projects, said Paulson, whose district include medical device companies.
