NASA may support SST x-plane

Science and resultant technology may well have made Low Boom supersonic flight practical. A 100 to 150 passenger aircraft could fly NY to LA in something like 2 hours, making one day two way coast to coast trips a practical comfortable reality for premium passengers. This has been impossible because of the glass breaking, cattle disturbing sonic boom, but now aerodynamics and aircraft technology have shown a road forward.

With the ending of NASA’s last ‘five year plan’ on ultra efficient airliners, money will be available to build a scale but largish (fighter sized I’d guess) x-plane to make test flights provingthe boom mitigating design techniques. This sounds like a great idea, the sort of thing that NASA should be doing, has been doing, quietly, since its founding as NACA all those decades ago.

3D printed Camera accessories for cool effects

Here is a simple Tilt-Shift adapter which will attach to any micro four thirds camera body and hold a Nikon Series E 50mm lens. This adapter will creates a tilt-shift effect or miniature effect in your photos (see examples below). This is intended to be a more durable and cheaper solution than both DIY and commercial lens adapters ($2100).

Cheating favors extinction…scientific proof of the obvious

This was the case when the environment was benign. But when those stable populations were suddenly exposed to a harsh environment, all of the pure co-operator populations survived, while just one of six mixed populations adapted to the fast deterioration in conditions, the researchers found.

Proving once more that scum proliferate in the good times and cause catastrophic collapse when the good times end…so it is with yeast so it was with Rome….

Cool Coolidge

From the Liberty Law Site: Silent Cals 6 Simple Rules

1. “Don’t hurry to legislate.”

2. Don’t promise much.

3. Economize.

4. “Don’t expect to build up the weak by pulling down the strong.”

5. The Meaning of Progress.

6. Humility.

Coolidge was not looking to return to the days of “horses and bayonets,” as Obama has joked. “We review the past,” he said, “not in order that we may return to it but that we may find in what direction, straight and clear, it points into the future.” Several of Coolidge’s speeches read like short history lessons, tracing the path of civilization from the Greeks and the Romans, to the Pilgrims and the Puritans, to Washington and Lincoln. To Coolidge, the history of western civilization culminated in the American founding.

Crystalline Time, what a great SiFi title!

It appears to violate conventional physics but does it? Seems like this has some chance of creating a link between ‘classic’ and Quantum physics, maybe?

Galactic Virgin Rockets Away!

Love the Logo-shot! The space ship’s pretty simple really, it’s biggest downside would seem to be no fly around capacity if one misses the runway line up, but 1) how often does that happen theses days? 2) if theirs any juice left in the oxidizer tank a short burn would do the trick. Anyone know the plan: depend on getting it right every time or lighting ‘er up for the go-round?

Duh! … Well intended policies have negative impacts …

Well-intentioned policies to make achieving tenure more family-friendly actually have negative consequences for the salaries of college faculty, says a study co-written by University of Illinois labor and employment relations professor Amit Kramer:
“The norm in academia is that success requires the focused pursuit of academic work at the expense of other responsibilities, including family,” he said. “That suggests that the use of these policies may be detrimental to the career outcomes of tenure-track faculty members. In particular, evaluators may perceive stopping the clock for family reasons as an indicator that the faculty member lacks the commitment to his or her academic role. And that, in turn, may constrain their career prospects.”

This ‘unintended consequence’ should have been predicted (and my bet is that it was) by any rational adult who has worked in even a moderately competitive workplace (and academia in main line universities is anything but just moderately competitive.) This sort of thing is a fact of life among us monkeys, move on, nothing to see here! Trying to add some kind of anti-bias bias, as suggested later in the article, is nuts and will only make things worse.

If you want to provide this sort of benefit, do so knowing there will be ‘unintended consequences’ of this sort and allow your adult, professional staff figure out their own best path. I think providing more personal days per year and allowing them to accrue along with a reasonably strict use policy to offset impacts to the company / coworkers would be more fair and flexible.
