…or at least as much as we think we do. Does the gravity model need to be adjusted?
In the one probe the researchers did not confirm a noticeable anomaly with, MESSENGER, the spacecraft approached the Earth at about latitude 31 degrees north and receded from the Earth at about latitude 32 degrees south. “This near-perfect symmetry about the equator seemed to result in a very small velocity change, in contrast to the five other flybys,” Anderson explained — so small no anomaly could be confirmed.
The five other flybys involved flights whose incoming and outgoing trajectories were asymmetrical with each other in terms of their orientation with Earth’s equator.
For instance, the NEAR mission approached Earth at about latitude 20 south and receded from the planet at about latitude 72 south. The spacecraft then seemed to fly 13 millimeters per second faster than expected. While this is just one-millionth of that probe’s total velocity, the precision of the velocity measurements was 0.1 millimeters per second, carried out as they were using radio waves bounced off the craft. This suggests the anomaly seen is real — and one needing an explanation.
Well, gravity just like evolution, is (in the words of anti-evolutionists) only a theory. It’s not reality–it’s simply an attempt to model it. And for most purposes, it does a pretty good job. But one of the reasons to do space, I think, is that it gives us new laboratories to make new discoveries about basic physics, the potential of which is unforeseeable.

In the 60 pages of words, there’s hardly a major new idea or an idea that departs significantly from the Democratic Party’s agenda since the New Deal. It’s all here: the activist government, the ambitious programs without reference to costs, the appeal to some people’s sense of victimization. There is also one striking omission–a list of anything that Senator Obama has actually done in the course of his brief career to advance any of these goals.
The point is that there is nothing here to back up a candidacy that is based on bringing the nation together to effect change. It’s a rehash of the same policies and programs that the Democratic Left has been pushing–largely without success–for the last 40 years. For some people, as least, the era of big government is not over.
I continue to be amazed at the willful self delusion on the part of the Democrats that either of their candidates are electable.

This isn’t new, but I’d never seen it before, and figured that many of my readers hadn’t either. The world’s only rotating canal lock. There’s more info at the usual source, of course. It’s a pretty clever design.
Over at Reason, the sad tale of a free-loader wannabe:
The group was now “out of food, hadn’t slept in days and were really cold,” and decided, in a grubby version of Dunkirk, to abandon the mission and head back to England. Boyles is disappointed-but not deterred. He is, the BBC reports, planning “to walk around the coast of Britain instead, learning French as he goes, so he can try again next year.” At which point the cycle begins anew, when, upon reaching Baden-Baden, the poor lad will realize that he should have also studied German.
As Wilde said in another context, one would have to have a heart of stone to read this and not laugh out loud.
