Yes, but in the case of the Baltic, there is a natural bias towards a no-oxygen situation.
In the baltic we have a higher salt concentration in the bottom parts than nearer the surface (due to water runoff through all the rivers which empty out i the baltic). At the same time, the mouth of the baltic (e.g. the Danish straits) are shallow, usually only alloowing te surface water to freely exchange with the North sea (and hence the Atlantic). In most cases there is a weak outgowing current in the danish straits and only in special weather situations do salt and oxygen containing water enter the baltic. The weather situations which may pump salt and oxygen into the baltic is large storms from the right direction and i recal readig that it is only about once every 2-3 years that that happens that significant amounts of salt water enters the deep parts of the baltic.
This phenomena (heavy salt rich water at the bottom, salt poor water at the surface) is also the same which makes the danish fjords vulnarable to hypoxia or anoxia (and incidently makes them nearly ideal for small submarines to operate in as a surface ship has no chance of hearing them through the thermo/hyalocline before they are close enough to launch torpedoes, which was the reason why the soviets took the danish navy serious durring the cold war).
There is alos other places where the geometry of the water basin results in natural anoxia (the black sea is i believe the largest). Similarly, in the geologic past, large costal water basins have been anoxic (as there is now oil there), so anoxic conditions is not by themselves some man made phenomena. It may be man made in the case in Oregon and in the case of the baltic, it surely does not help dumping all the polution from the rivers..
Not to mention the great hungers in Russia in the 1920's and 30's (managed by Stalin in order to satisfy his power base in the big cities and at the same time eliminate the oposition in the cuntryside due to forced colectivisation and starvation)

They also managed to kill some Al Caida chief in Yemen a few years back by using an armed drone (predator drone) after they pinpointed him in a car in the desert. I think they tracked in on his cell phone as he used it and used the attack drone to drop an anti-tank rocket (Hellfire missile?) on his car (as far as i recall not much was left of the car).
Santa doesn't live at the magnetic North Pole, silly.
Exactly, as the magnetic north pole is somewhere in Antarctica (or close to, cant remember). The north pole on the compass points north due to the magnetic south pole there (somewhere between Canada or Siberia depending on time).
Well it would still create havoc on costal cities like Los Angeles etc. (not to mention some thousand small south pacific atolls which is ony a few meters above sea level). Granted it would not eradicate Los Angles, but likely smash some seafront buildings (still a mess).
Well this idea is hardly a new one. Buzz Aldrin (Yes the one who went to the Moon) came up with it in his novel 'Encounter with Tiber' (which is rather interesting btw.).
And who knows, it may help funding future space projects. I know for sure that i would buy a $1 chance if it was offered, no matter how little the chance was for actually going into orbit.:-)
But also no inventions within the field of manufacturing/production were made in the south as opposed to the north which had the industrialisation progressing with some inventions beeing made.
The rich southerners spent too much time enjoying their fortunes and too little time improoving the effectiveness of their slaves (better working environment, more technical farm implements etc..) as they themselves had hardly any experince with the actual production and the slaves had no incentive to be inventive as they themselves would get nothing out of it.
Yep, but as ohters have said, the greeks used slave labour for their construction/manufacturing and therefore had little incitement to invent other things than warmachines (greek fire, imagine a giant roman candle) and toys (as in this example with 'agitated air' as he called it as far as i remember).
First of all, if you actually RTFA, these microchips generate no heat, which also suggests that they are very low power.
Well if I recall correctly, the all permanetly magnetic materials do posess a property called hysteresis which acts like a resistance to change in the magnetic strength and direction of a ferromagnetic material. If you switch the magnetic moment of such a domain in a ferromagnetic material enough times, heat will be generated. It is possible that is is less than for electronic gates, but i would say that the artificial relocation of a magnetic domain wall in a ferromagnetic material would result in somme loss in the material which would manifest itself as heat.
Personally i think that Robo Rally is best with a group ov nerds and a crate of beer, but seriously, I can see that it could actually be used for educational purpose for kids, as there is a degree of exitement in the game (will i get to xxx without getting more shot up so i can repair?).
At the same time educate something about the strict logical rules of programming (that a computer will do *precicely* what you programmed it to do without any consideration about the surroundings or change in the conditions the programmer did not anticipate) in a fun way (as learning it the hard way in front of a real computer can be quite fustrating as we all know...).
Besides you can not really do something to prevent hurricanes as they are 'fueled' by hot ocean water and you really can not do anything about some 50000 square kms of ocean which happens to be above some 28C (AFAIRC) a few months each year..
It's correct that fault moovement and plate tectonics does not require water or other fluids, but in the majority of cases large shear-zones and falut systems show that water or other fluids (CO2, SO2) may have contributed to the ease of moovement. For instance in many thrust fault systems the sole throust is often located in shales which is rich in hyrdous minerals such as biotite, muscovite, chlorite or clay minerals. These minerals often act as the geological equvivalent of grease.
In the case of thrust faluts / shear-zones in sand stones or quarzites, it is also believed that small amount of H2O molecules within the quarz structure may facilitate crystal deformation by breaking Si-O-Si bonds close to the dislocations in the crystal structure.
Yep, The evolution of the 'cyano bacteria' (which can 'run' in both reducing and oxidizing environments, that with and without free oxygen) caused the biggest and most far reaching ecologic sdsiaster this planet has ever witnesed. Now only some deap sea hot springs (black smokers etc) and other special areas on earth exsists where the bacteria who evolved before said cyanos can still thrive (and those places can be the place for some realy bizare life forms.
While it is correct that the corona/tail of a comet makes it easy to identify within Jupiter's orbit, the speed (60+ km/s) of the long time comets (the ones form the Kuiper belt) would only leave less than one year from discovery to impact. The first 2 month's would likely go to determining the exact trajectory of said comet, and that leaves us with only 8 to 10 months to come up with a plan AND implementing said plan.
In order to do something against a comet/asteroid you also have to give it a 'gentle nudge' far before impact (several months) in order to change the trajectroy suficiently to awoid impact (remember that the 'crosssection of impact on earth' is larger than the earth's diameter due to earth's gravity.
The 'gentle nudge' mentioned above would likely have to be one or more thermonuclear devices with yield in the MT range... (perhaps some of the types of fusion deices developed for the Orion Project in the late 50'es early 60'es.
The above observations makes it extremely dificult to do something against a comet and although they are only 'dirty smowballs' they still pack a punsh when one considers the kinetic energy of an object with a diameter of 1 mile, an aveage density half of that of water and a speed of 60 km/s (Kinetic Kill anyone??).
Actually basaltic magma/lava is generally richer in magnesium than iron except in highly differentiatied magmas/lavas.
For a pristine lava tha ratio between magnesium and iron i likely 3-1 whereas (in extreme cases 10-1 for precambrian ultramafic lavas) in evolved (differentiated) lavas the ratio may be as low as 0.01-1.
In the case of Oregon the magma is andesittic to rhyolitic and whereas rhyolite may be poor in iron it is definitely poorer in magnesium.
If the magma is andesittic, then the iron - magnesium ratio is likely approx 1-1.
An other explanation of a fast star leaving the galaxy is a 'slingshot' trajectory close to some other star. One of the stars would loose energy (and fall towards the galactic center) and the other would gain energy and possibly achieve escape velocity.
The slingshot principle has been used for a number of spacecrafts and there is a number of trajectories which could transfer momentum between two objects traveling in a common gravity well (e.g. galaxy or solar system).
Not to mention the soviet FOBS-system (or here) (Fractional orbital bombardment system) which vould put a 1 to 3 megaton nuclear warhead in low orbit and have it ready to de-obit and detonate at a specified time over any country.
If you try this, the universe would have to do something drastic to prevent the rest of the universe knowledge of what happened.
This would either be by creating an event horizon arround the cat + toast or by preventing the cat from ever falling (which seems to violate the principle of determinism in the universe or at least something about time travel).
The creation of a event horizon would on the other hand solve the problem form the point of view of the universe, as no information abot what happened would ever escape.
The bad part about this (from our point of view) would be that anything crossing the event horizon arround the cat+toast would stay inside (in effect creating a black hole) which would eventually eat the whole earth.
Come to think of it. Astronomers always wants to study the curvature of spacetime arround a spinning black hole. If they did this experiemnt (somewhere safe like on the moon) and instead of just dropping the cat sent it spinning towards the floor, the conservation of momentum vould create a spinning black hole once the cat+toast almost hit the ground. If done properly, the moon would be transformed to a spinning black hole which could be investigated safley and cheaply by normal astronomy, thus awouding the use of hugely expensive space based telescopes.
At the same time, a spinning black hole conviniently close to the earth could also possibly be used for FTL spaceflight by use of wormholes created close to the event horizon.
Note do not say this to greenpeace etc, they'll likely crucify me for suggesting this..:-)
1000 lbs, that's like 500 kg or half a ton, I think both the US and Russia has fusion warheads that small.
Think about the MIRW technology for the ICBM's, The sattelite versions of the missiles can loft a 5 ton sattelite into orbit, but at the same time can loft a MIRV (with multiple warheads) half way across the world.
After approx 1 min of googling i found this link to the W88 warhead with an approx weight of less than 800 lbs and a yield of approx 450 kton (a fusion device to be sure).
Yep normal small marine radars can detect rain (atleast in the case of bad squalls or thunderstorms). My dad has a boat with such a unit and countless times we have been able to see where there was heavy rain (within a 10 mile radius).
Not to mention the Vorlon super-beam on their planetkillers in season 4. They had the same destructive power as the dreaded death star beam in StarWars although they had a much more sinister firing sequence where you could see that the entire Vorlon ship was basically just one big gun as the ship started gathering energy at the back and then energy proceeded along the perimeter of the ship untill it reached the front with the actual gun-mount.
