    It just occurred to me that air pressure depends on two things, altitude AND weather :). Usually during storms the air pressure would drop significantly even on the sea level, and similar could be expected on the mountain. Maybe that time altitude + storm meant lower air pressure than her previous higher altitudes in good weather?

    I climb and study meteorology. You've given me a very nice question to think about :). What you say about edemas is probably very true, but maybe this is an additional reason to take storms extremely seriously?

  3. Re:How Big the Earth, How Thin the Crust on Birth of the Moon: a Runaway Nuclear Reaction? · · Score: 1

    The idea is true, one detail is not. Earth's mantle is mostly solid, so of our small model earth, nearly half of the diameter is solid matter. It's viscous and capable of flow though.

    How do we know this? That's because S-waves (waves vibrating in a direction perpendicular to the propagation of sound) can only happen in solids. Think of the vibration of a tuning fork, for example. S-waves travel very well in the mantle. S-waves, however, don't enter the liquid outer core at all (which is why we know it's liquid ;).

    So, once again, our everyday "wisdom" about what a stone is, is at fault. During very long times, stones deform. Sagging is becoming apparent even in some old marble benches on the surface of the earth. And stones deform much more readily in the huge pressures of the mantle.

  6. Changes in the environment on Geneticist Claims Human Evolution Is Over · · Score: 1

    In the last millennia, we've seen huge changes in the environment. Not surprisingly, evolution is currently very fast.

    For some reason people often forget evolution is not only about survival, it's about procreation. And that's about many many details. One strong driving factor in evolution is who we choose to breed with - today, we have more options than ever in all possible ways. Why are many people so beautiful today? Because of evolution from choosing companions. We choose whom we breed with, and not nearly everyone ever has (or ever has had) kids, no matter if they die young or not.

    More and more, people choose to not have kids. If you trust their capability of not having kids (and the technological means are unforeseen), that's going to drive evolution and rather strongly. I personally think people from happy families are more likely to want families of their own, which keeps evolution going the right way too.

  8. Re:Climate Science on New Study Shows Solar System Is Uncommon · · Score: 1

    For example, if I cough outside facing north, it's NOT going to cause a pressure system to sweep the northern continent. By the same token, if I stand on the coast of southern Africa and sneeze west, it is NOT going to cause a hurricane.

    Suppose you cough outside and accidentally blow out a candle. A young waitress comes to light it again, and a driver of an oil truck gets distracted by the sight and the truck moves a foot to the left, causing a collision with another truck. The oil spills and burns because of the candles, causing a forest burn that spreads over a very large area because it happened to be a dry period. That caused large clouds of smoke that obscured the sun, cooling down the ground, and altering the weather patterns on a large-ish scale (even worldwide, if it was a very large forest fire ;).

    The example is entirely artificial, but similar chains of cause and effect also exist in nature, just maybe not as probable or potent.

    Suppose the butterfly flaps its wings. So the wings are vertical instead of horizontal - more sunlight goes into the pond that warms up more, and so more water was evaporated. The cloud above receives more water vapor, and thus rain starts two seconds earlier than otherwise. Because the cloud was moving, that also means the rain is in a slightly different place than it would have been, so more water fell on the lake on the mountain, raising the water level and causing the natural dam to collapse, resulting in a flash flood. That knocked down forest, dug a river valley deeper by many meters, and covered a large field with mud. That would alter surface albedo and wind patterns in the area, and thus local weather, which is a component in the global weather.

    There are other processes that don't require interaction with solid matter but which are equally valid. Of course neither example above is very likely - most of the time small changes fail to push the events over the limits. Even then, that is possible.

    Most of the time you coughing northwards will only add some very little momentum northward. So the weather system moving east-west will maybe be 1 millimeter more north than it would be, after traveling 1000 km west. Everything depends on everything, so the evolution of weather is changed, and everything else will also be in a different place than otherwise. Very small changes in directions or velocities will become apparent over long distances and time frames.

    By the way, the weather predictions are usually very good in predicting what's going to happen. The inaccuracies lie in when and where things will happen ;). If rain is predicted, maybe it'll be 100 km off and three hours later. That's because directions and velocities used in the prediction were slightly off. And they can be slightly off for very small reasons.

    The evidence that accurate modeling can be done is right there for everybody to see, in most movies..

    But hence, with large modeling, comes large innaccuracies. My main point is that these models are based on a correlation of temperature increase with increased CO2 and yet this doesn't seem to be the case....which makes the models in themselves suspect.

    No, that's not true. These models are based on a correlation of CO2 and absorption of certain wavelengths. What the models show is that if more CO2 means more absorption, then that means warmer atmosphere. Also, that CO2 absorbs some wavelengths can be and has been measured in a lab, we know that for sure.

    Further, what IPCC has done is running lots and lots of different models with both slightly different initial conditions and mechanics.

    I don't think GP was saying anything about his beliefs. He was talking about a claim that faith is dangerous, something which is based on evidence. He even said why. Of course not all faith is equally dangerous, and modern christianity is already quite peaceful. No dogmatic system can be perfect though, and religious thought can not control which religion people end up adopting.

    Physicist and Nobel prizewinner Stephen Weinberg describes religion as an insult to human dignity. 'Without it,' he says, 'you'd have good people doing good things and evil people doing evil things. But for good people to do evil things, it takes religion.'

    In my view, it is fundamentally irresponsible behavior to let anyone else tell you what things are right and what things are wrong. Religion is a method of doing just that, globally and systematically. You will most probably agree with me that this indeed is dangerous.

    I've nothing against religious people trying to convince me their religion is right, as long as they respect the discussion with logical arguments. I always find out religious arguments are very bad, and scientific ones superior. Nor religious nor scientific ideas should be respected just because they are ideas.

    If a being is all knowing, exists outside of time, and has absolute control over all matter, how -- you being limited in knowledge, and physically limited by time and space -- do you propose that you would be able to find any evidence of such a being's meddling? Logically, they could instantaneously cover up any such changes to the fabric of reality.

    By the virtue of looking. We have good knowledge about the physical laws of nature, and can make predictions with them. If reality significantly differs from prediction, that's evidence for meddling. At least if that difference is inconsistent - a consistent deviation from predictions would probably be explained by another law of nature we didn't know before.

    A god is free to convert water into wine, and I am free to remember that wine used to be water and thus know that a miraculous thing happened. That's pretty much the point - if a miracle happened, people could tell that it's a miracle. Such miracles don't happen.

    Yeah, a god could cover up any changes he makes, but that would necessarily include meddling with the brains of all living beings and all stored information, texts, audio and video. Because if only the scientists oddly forgot things when researching for something, other people would notice.

    If a god would regularly meddle with world affairs and in doing so would fix everybody's memories and all other stored data, I'd very much choose to not worship such a sod!

    Anyway, I don't specifically believe in god, but I don't specifically disbelieve in god, either, and there's a lot more to religion for most people than simply "god said there was no dinosaurs". It gives them comfort in times of grief, it gives them hope for the future, it gives them faith that other people can be good people.

    You're making a fair and important point here and I mostly agree. Not all religious views though, and not only religious views, have that property. Atheists I know don't seem to be any worse off than religious people I know. That's partly explained by the fact that hardship makes people more vulnerable to religion, so it's difficult to calculate the net benefit..

    In any case, religion is dangerous. It necessarily involves the belief that one is right and righteous and others are less so. I find religious politicians are often the bad ones.

    If you're actually interested in things that give comfort and hope, I heartily recommend "Ancient Wisdom, Modern World" by Dalai Lama. In it he deliberately avoids religion and uses common human experience in building a wonderful basis for a good life =).

Such a god MUST leave behind evidence. If he does something that has a significant effect, that effect must be measurable. Because science is simply careful looking at the evidence and science does not see such an effect, it's outrageous to claim such effects still exist.
