Comment mouse central vision != primate central vision (Score 1) 105

While this finding is interesting it's not the first time neuroscientists have found complicated functions being performed in the retina of non-primates; the extrapolation in the summary to implications on human vision is a bit of stretch. Mice have poor high-frequency vision, but they can sort of make up for it with vision that's sensitive to motion. Many others mammal have this feature as well (rabbits, cats, etc).

Data show that having children decreases happiness.

Since when were scientists ever concerned about happiness. If they were, they wouldn't be in such an often-unrewarded (financially, emotionally, etc.) profession. Scientists are happiest when they can bring some sort of meaning and structure to what appears to be chaos. Arguably, children are the ultimate form of chaos!

They also eat a lot of your time (which could be better spent doing science)

No doubt. I'd wager that the majority of the most successful scientists (in terms of publications, innovations, peer respect, etc) are that way because they devote the vast majority of their time to science and nothing else.

and they're extremely expensive (scientists don't get paid that much).

Children can cost plenty but our memory is selective; we often ignore the constant "cons" for a few blissful, and unfortunately infrequent, "pros". In the end, you're probably right that logically, people that make science their raison d'être shouldn't have children. Fortunately for society, these people do as they often encourage the next batch of new scientists...

It's one thing to monitor traffic for things like accidents and traffic jams, but NYC traffic is its own beast. While there are certain times of the day (morning/evening rush periods, midday lunch, etc) when there is heavy congestion that lasts for an hour at a time, a lot of times you get these little jams due to someone double parking, etc that lasts for 25-30 minutes tops. And they're more or less randomly distributed around the residential areas of Manhattan. Constantly rerouting to avoid these situations in NYC sounds like a nightmare. For instance, you could avoid all the congestion but take a circuitous route (25-30 minutes local - downtown to uptown), or you could sit through 10 minutes of congestion to get onto the FDR or West Side Highway + 15 minutes of driving. In the end, you're better off just listening to the cabbie for advice. While it's possible he might want to rip you off, more often than not, he wants to get you to your location fast for A) a better tip and B) so he can get more cab hires a day.

Comment Re:simulate 3d for those with only one eye? (Score 1) 261

There are numerous monocular depth cues available, but you won't "see" in 3D; you'll just know you're viewing a 3D world. The answer to you question depends on what exactly you're referring to by "simulate 3d."

If it's just depth perception, then.. you can use motion parallax, occlusion, kinetic depth perception (when objects change size, while your viewpoint remains fixed), perspective lines, spatial frequency/texture gradients, etc..
