Several kilometes of mud would have a fair inertia. Blocking the flow rapidl;y could lead to the same effect as "Water Hammer", with devastating consequences.
And that's why you're a first year, where they teach you perfect "ideal" models.
In the real world it's not a static condition. The well hole will have resistance to flow, as such there will be a gradual pressure drop over it's length. As you plug near the surface the flow is reduced, thus reducing resistance based pressure losses, and the pressure in the rest of the well hole will increase.
Microwaves cause resonance in water molecules, but plenty of other materials will attenuate (absorb) the signal. With a continuous 800W, the energy has to go somewhere!
They wont timeout. If there is no webserver running on localhost, a "Port Unreachable" ICMP message will be returned instantly and the connection will close.
The sniper could quite easily be pointing in a different direction - the muzzle blast is going to be spreading out in all directions whereas his scope is quite limited.
I think you're being a bit pedantic in this case. Everyone understands what it meaans to "kill" a virus, even though a virus may or may not be defined as alive.
The kinetic energy of the recoil will be precisely equal to the kinetic energy of the projectile.
Just being pedantic, but that's not quite right.
1) From Newton, we understand that the force of the recoild is the same as the force applied to the projectile. 2) We also know that momentum must be conserved: the mass * velocity of the shell = mass * velocity of the ship. Since the ship is vastly heavier than the shell, it will have a very small velocity change. 3) When we relate that to energy (1/2 * mass * velocity^2), the kinetic energy imparted to the ship will tiny compared to the projectile due to the squared term.
You can have very strong mangetic fields without them leaking all over the place - you just need to give them a preferential path to flow though. You'd have to assume they've covered that base - after all it would improve their efficiency to be using high permeability cores rather than free air.
Many lithium batteries are already segmented into regular cells - the problem is that one cell dieing can generate the heat to put others over the edge.
Most animals don't have the technology to damage the planet that much. For example - if some seals eat all of the penguins in an area, the local seals then starve and the penguins repopulate. We humans can go beyond that and wipe out something on the whole planet before we even realize it.
Western Australia has exactly the same issue. Until recently (a month ago) we didnt have daylight savings, then the politicians decided to spring a 3 year trial on us.
The Microsoft patch Daylight savings system has no concept of the year, so software now thinks that every year has and always will be daylight savings.
Whilst I whole-heartedly agree, the problem is where do you draw the line? Can you treat earthworms and fish the same way as chickens? What's the test for animal sentience?

The leap of faith required between Aliens and God is an order of magnitude:
Statistically it's likely that other planets out there support life, and some of them might be advanced enough for space travel. It's a significant but not unrealistic improvement on our own position/technology.
"God" in the biblical form requires an immense level of magic to explain.
Alot of industrial or sensitive sites (specifically Airports) dont allow cameras or even camera phones, so I'm not completely suprised there's no pictures.
Where I come from, it's not that hard to get ethically raised free range animals. You just need to stop shopping at the big supermarket chains and see a real butcher.
The problem is, we dont truly know the quality of an animal's meat until it's been slaughtered, and by then it's too late to produce offspring. Even then most male animals sent for slaughter are sterilised when they're young.
Breeding plays a massive part, but choosing a good breeder is a long, expensive process. If we can use cloning we get a short, expensive process, but ultimately more cost effective with better control. Samples can be taken from a freshly killed and graded beast and a new clone made from there.
PS - personally I would rather see cyclists riding slowly on the sidewalk as it's much safer for them and less impact on the traffic avoiding them. That said, you shouldn't have your cake and eat it too - it's either sidewalk or road user, not both!
Every time I see that cyclist going past me, it's because they've ignored a red light and have pretended to be "pedestrians with wheels" for a moment. As soon as the traffic starts flowing they want to be given space and treated like a vehicle again.

Pressure is constant

I guess we could go on playing this shifting game...
Its not modern professional demands in husbands and _wifes_, its the parents.
You're right,
It's not the self centered need for money and "things", it's the modern professional demands in husbands and _wifes_

How many Volkswagon Beetles is that? Is it equivalent to 1 Library of Congress at 0.01mph?

I wish I had mod points for that comment. Most insightful yet.
Making sense or not, temperature is a pretty arbitary unit. The big drivers for using Celsius are:
1) The Celsius and Kelvin scales line up - a change of 1 degC is equivalent to a change of 1 degK. This is very useful for the scientific community.
2) The rest of the world uses Celsius

"i've no doubt that veggies do have much better nutrition than average."
I'm not trying to be unhelpfull, but nearly every vegetarian I've known looks like death warmed over.
The dust does collect, but fortunatley a few lucky dust devils have cleaned things off.
Just to be pedantic, I thought a Steer was a sterilised male, hence it can't breed.
