[Akhier the Dragon hearted]

We're operating on the "THIS. IS. DWARF FORTRESS!" Model of flight.  Specifically, the this is an alpha model.

Also known as the "Shit keeps flying until it stops" model of flight.

And the shit only stops when its hitting your face.

[CobaltKobold]

which is, in fact, the impetus model of flight. Things fly until they run out of impetus, then fall.

And no, things will fly variable distances when hit at angles that don't support the "until it hits something"

"The energy per unit mass (9×1016 J/kg) is about 10 orders of magnitude greater than chemical energy (compared to TNT at 4.2×106 J/kg, and formation of water at 1.56×107 J/kg), about 4 orders of magnitude greater than nuclear energy that can be liberated today using nuclear fission (about 40 MeV per 238U nucleus transmuted to Lead, or 1.5×1013 J/kg), and about 2 orders of magnitude greater than the best possible from fusion (about 6.3×1014 J/kg for the proton-proton chain). The reaction of 1 kg of antimatter with 1 kg of matter would produce 1.8×1017 J (180 petajoules) of energy (by the mass-energy equivalence formula E = mc˛), or the rough equivalent of 47 megatons of TNT. For comparison, Tsar Bomba, the largest nuclear weapon ever detonated, reacted an estimated yield of 50 Megatons, which required the use of hundreds of kilograms of fissile material (Uranium/Plutonium)."

The Tsar Bomba was actually designed as a 100 megaton device but the Soviets removed some of the fissile material before the test because they were afraid that testing a 100 megaton device would produce enough fallout to make large areas of their country uninhabitable...

However, that little tidbit still does nothing to detract from the point that Alway made about antimatter, which is correct.

Well, it was tested far away, on the northernmost point of an island in the Arctic so it wouldn't contaminate any settlements. The payload was also halved in order for the plane that dropped it to be able to get out of range (it did). Also, way too much stuff to waste on a test, was big enough already.

Regarding the matter of real importance - don't bring your fancy physics into Dwarf Fortress. Here we live by the law of Armok and ale, and we know no Newton or any other elvish-sounding names.

[Darvi]

*checks date* Eh, whatever.

[Lagslayer]

N-N-N-NECRO!

[Bohandas]

yeah, sorry about that. I found this thread while running a search for another thread, and didn't see how old it was until I had already written half of my response, and wasn't about to decide not to post after having already figured out exactly what I was going to say...

xD  Nice...

[Dreggon]

Dwarven constructions are powered by the force of physicists spinning in their graves.

[Demicus]

What made me laugh, is I had to do a school homework over the physics in a video game. I chose Dwarf Frtress. Then I found this thread. XD

[Hans Lemurson]

If you describe in detail exactly WHY each of the various physics-breaking things in DF do in fact violate physics, then you'll get an A.

Here's a good question to ponder: Which part of a water-reactor is the violator of physics?

the entire bit?  flaw one:  friction unaccounted for.  flaw two:  generating more energy from falling water than the water has.  conservation of energy is broken by DWRs

[Hans Lemurson]

Friction IS accounted for.  Every piece of machinery has a "power cost" associated with it.

I personally think that the fault lies in the pump ITSELF.  It's power-requirements are far too low given the amount of water it can move.  A pump's flow-rate is limited ONLY by how quickly its intake is replenished.  For 10 power, that's a bargain!  Gear mechanisms use 5, for comparison.

[hostergaard]

Conservation of matter.

I have created several tons of food yet there is no change in the fields.

My dwarfs have eaten vast amounts of food and consumed enough alcohol to fill a river yet they never expel any of that matter.
