I would think that this sort of technology would be tried out on commercial vehicles (long-haul trucks, local delivery vehicles, taxis, etc.) first, before letting it loose on amateur drivers. I also think it is high time to replace Chicago's CTA drivers (especially on the 'L') with this technology.

+ - Fish raised on land give clues to how early animals left the seas->

sciencehabit (1205606) writes "When raised on land, a primitive, air-breathing fish walks much better than its water-raised comrades, according to a new study. The landlubbers even undergo skeletal changes that improve their locomotion. The work may provide clues to how the first swimmers adapted to terrestrial life. The study suggests that the ability of a developing organism to adjust to new conditions—its so-called developmental plasticity—may have played a role in the transition from sea to land."

You think your argument is strong with Sun containing 98% of the Solar system's total mass? It is actually something like 99.8%!!

Yep. Here's a good source for the relative masses of the solar system object: http://en.wikipedia.org/wiki/List_of_Solar_System_objects_by_size#List. It does not include the Oort Cloud, which is though to contain about 5 Earth masses of material.

Might it be one of the most expensive movies ever?

Asks an ignorant troll...

Considering it was made with 25 year old footage, it was probably one of the cheapest movies ever made.

The U.S. spends $324 billion dollars a year on entertainment*. tThe cost of the Voyager II program ($865 million dollars*) over 40 years is equal to about 22 millon dollars per year. A drop in the bucket. The Pioneer and Voyager missions have spawned an entire cottage industry of "science-based edutainment shows" on TV like "Through the Wormhole" and "Cosmos". That program has paid for itself many, many times over.

How do we determine how much to spend on stuff with little or no payback?

I have no idea. But the Voyager mission has certainly paid for itself many times over.

1 1 was a race-horse, 2 2 was 1 2. When 1 1 1 1 race, 2 2 1 1 2.
