  2. Re:Islands have high gravity? on Researchers Develop the Most Detailed Map of Gravitational Variations Ever · · Score: 1

    Also, looking at the world map, it is a map of Bougeur anomalies (or using some other correction), which are gravitational anomalies corrected for the elevation they are taken at and the mass of the topography. That is why a good portion of mountainous areas are shown in red.

    The map of Australia is just straight-up gravity (and is different from Australia in the global anomaly map).

  3. Re:Islands have high gravity? on Researchers Develop the Most Detailed Map of Gravitational Variations Ever · · Score: 1

    From Newton, the gravitational potential from a point source is mass*G/distance. With topography, there are two things acting. Because mountains are high, they are further away from the Earth's center of mass (typically, the Earth's gravitational potential map is modeled as a multipole expansion of Legendre polynomials centered at point source at the center of the earth).

    However, there is also the gravity of the mountain(s) itself pulling you down. In most mountain ranges, there is lower gravity because of isostasy. The crust is floating on the mantle. Contintental crust is less dense than oceanic crust, and thicker. That is why it is higher than the floor of the ocean. It floats up more like a piece of styrofoam on water. Mountain ranges like the himalaya usually have thicker crust which displaces more of the upper mantle around it than thinner crust in places like Missouri. The crust in the Himalaya/Tibet is around 70 km thick, whereas normal continental crust is more like 30. Assuming close to isostatic equilibrium, from buoyancy the 70 km thick crust (averaging 5 km in elevation so 65 km below sea level) has roughly the same weight as 30 kilometer thick non-montane crust + 35 km of mantle.

    However, in the mountains, you are further away from the center of the earth, so there is less gravity.

    Seamounts are a different story. They are small, so instead of being in isostatic equilibrium the crust supports them like an elastic beam. They are also made out of heavy oceanic crust. That means they have high gravity because their mass isn't compensated. However, they do sink eventually. That is why if you look at the Hawaii/Emporer seamount chain, the Big Island is the newest and highest, while they get lower and eventually are no longer above sea level as you get older.

  5. I'm thinking more about intra-military rape, which is actually frar more common. If you've been paying attention the last few years, the military has a history of covering up rape instead of prosecuting. For example, a few years ago a female soldier in Iraq named Laveena Johnson was found dead with a broken nose, black eye, loose teeth, a gunshot wound, and chemical burns to the genitals. It was ruled a suicide.

    H1Bs are effectively the same thing as outsourcing. Temporary cheap labor, and then they go back to where they came from.

    Real permanent immigrants (especially skilled ones) are a net benefit as they tend to be entreprenurial and create jobs. H1Bs can't start a business. They are cheap labor benefiting corporations like MS at the expense of American workers. That's it.

  12. Re:Water, or liquid. on Ancient Mars Ocean Found? · · Score: 1

    Like the other poster said, not at the pressures you see on Mars, and not at normal temperatures. Ice can't even exist on the surface of Mars without sublimating away. If it occured in the past when atmospheric pressure was higher, then the temperature would have been higher from the greenhouse effect, meaning that it wouldn't be cold enough anyway.

    Also, Mars has an oxidizing atmosphere, hence the red color. That isn't compatible with free hydrocarbons on the surface. That and you'd need a lot of hydrocarbons for an ocean. You only see that in the outer solar system where things are much colder.

    Considering that Mars currently has loads of permafrost and current rock glaciers, as well as evidence of nearer-past glaciation, liquid water is a much more parsimonius answer.

  15. Re:When you ride at night, on Lead Developer of Yum Killed In Hit-and-run · · Score: 1

    Actually riding on the sidewalk is much more dangerous. Cars do not expect fast moving vehicles on the sidewalk, and it is comon to be hit in driveways/crosswalks. Cyclists do best as part of traffic. Even bike lanes are more risky than a shared lane, because drivers aren't accustomed to looking to the side, making for tons of left or right hook crashes. Of course, widely available bike lanes increase bike commuting by quite a lot, and there as a huge safety benefit from numbers (because drivers come to expect cyclists).

      Despite how dangerous people think it is, cycling is actually slightly less dangerous per mile than walking. It's only three times as dangerous in terms of fatalities/mile as driving. That is of course outweighed by the health benefits many times over. And you are more likely to get laid.

    Yeah, I don't trust heavily patched packages for security. It's better to let the people who actually write the software do updates.

    I could point out that some research on both sides are utterly crap. funding the study of beetles migration habits? yeah I dont think we need to waste money on that one

    This really, really fucking irks me.

    I often hear laypeople dismissing research they don't understand as "being pointless." Just like Bobby Jindal's dismissal of the USGS spending money on "something called volcano monitoring."

    People don't do research that is pointless. Research is hard and you don't get paid well. You just don't understand the purpose of particular work without understanding the context. It's easy to dismiss something out of hand without understanding the context. Look at other responder's posts about where beetles are very fucking relevant.
