I believe it is you who is confused. Let's say your goal is to quadruple the damage done by your projectile by doubling its velocity. By conservation of momentum, this will double the velocity of the recoil. Which quadruples the kinetic velocity of the recoiling weapon, which directly equates to the damage done to your shoulder. Amazing how it all works out, isn't it?
What you remember from your first-year physics is more like a feeling of almost having understood what work is, without actually understanding it.
The technical argument for combining flash and spinning media in a single package is weak to nonexistent. It is far better to have the devices at different levels in the storage hierarchy separate and fully under control of the OS and applications, and have both devices be cheaper. The use case for spinning media in portable devices is vanishing fast and increasingly you will only see spinning media in online archive setups and huge databases. There is no advantage whatsoever to combining flash and spinning media in those setups, and only disadvantages like mismatched media lifetime.
We don't know the mass of the ammo (needles?), it's velocity or how much the boat moved, so it works in the book.
Maybe it worked for you. Those depleted uranium needs went right through a patrol boat and sunk it. Doesn't work for me without an explanation of what happened to all the equal and opposite. Left me with a big oh yeah right, magic is real.
How much dwarf-tossing is strictly necessary. I think LOTR had one.
Wrong, two: once in the escape from Moria and again in the defence of Helm's Deep. And now that you remind me, the tipping rock sequence was just plain stupid and needless to say none of this came from the books. The right amount of dwarf tossing is: zero. Tolkien didn't write it and it is offensive (full disclosure: I am not a dwarf).
How big should giant elephant-like beasts be.
Big, but not the size of hot air balloons. Come on, it's hard enough to suspend disbelief as it is. Bigger does not necessary equate to better.
In nearly all the cases where the screenwriters departed radically from the story, the departure was unnecessary and not as good as the original. This is a weakness that screenwriters and directors tend to have: they feel compelled to add their own changes whether or not they detract from the original work just to show they are not a mere servant of the author. But this is just plain bad attitude.
Not to say LoTR is anything less than monumental, but it is not without flaws, far from it.
Kinetic energy is 1/2*Mass*Velocity^2 . Momentum (which is the cause of recoil) is simply Mass*Velocity. So, if the projectiles have very low mass, but are travelling very fast (consistent with the description of Reason), the recoil would not be heavy even though the delivered kinetic energy is high.
Oh nice, you just refuted Newton's third law. Now I await with breathless anticipation the announcement of your star drive.
What lack of recoil? The gun moved the boat. That's recoil.
See, you perfectly demonstrated why they need an actual physicist. Not enough recoil for the energy that was transfered to the depleted uranium fleshettes. Why bother with the nod to the believable depleted uranium idea if the rest of the physics is just a mockery? I'm willing to suspend my disbelief on the question of packing a nuclear power plant into a suitcase without shielding, but not simple Newtonian mechanics.
Wow, so what movies do you think didn't suck at all?
Lord or the rings? Except for a few stupid lapses like ridiculously oversized elephants, unecessary dwarf tossing and excessive reliance on the ghost army to win the day at Minas Tirith.
I just watched Lawrence of Arabia and was incredibly impressed. Nobody can afford to make movies like that any more, it would cost billions.
Silicon graphics had little influence one way or the other on the progress of Linux
Wrong on three counts. 1) OpenGL has a huge influence on Linux and 2) A number of Irix design elements were incorporated into Linux and 3) SGI engineers were (and still are) huge contributors to Linux, providing much of the memory scaling infrastructure for one thing, and the respectable if now somewhat dated XFS filesytem.
It's really too bad that the company currently known as SGI has only the name in common with the SGI of yore.
Not actually true. The company formerly known as Rackable Systems also has many of the former SGI engineers in common, and the Altix technololgy. What's gone is the original corporate, the flashy headquarters (now inhabited, hermit crab-like, by Google) and the graphics business, which is now owned by we, the people.
No offense, but Linux and hardware acceleration? NOT the best of friends, in fact the only one I've seen do it consistently is Nvidia and that is only with proprietary drivers which rumor has it guts a lot of the graphics subsystem and replaces it with their own.
You're basically talking out of your ass. AMD's proprietary catalyst driver turns in roughly the same performance as NVidia's driver, and the open source Radeon driver is perfectly usable, impressive even, provided you stick to core OpenGL, which you should anyway. I don't bother running Catalyst any more for that reason. And for your information it is normal for an OpenGL hardware driver to reimplement as much of the "graphics subsystem" as possible within itself. But like any other OpenGL driver on Linux, NVidia relies on GLX for DMA to the card, which works perfectly well.

I'm getting 75 million phong shaded triangles per second at 1920x1200 using the open source Radeon driver on a fanless 6450. If that isn't hardware acceleration, what is? The Intel driver is also turning in a respectable performance lately, not in that class but respectable.
Let's hope it isn't anything like the second and third matrix movies. And not very much like the original Matrix either, which actually kind of sucked in many respects but got a pass for its stylish moments and of course gave us some nice scren savers.
Then the nice man from the DoJ says "yeah then why do you sell this chip for $1 while selling that chip for $100 when they cost the same to make?" Busted.
Right, that's pretty extreme isn't? But there's a floating point divide. I don't know about you, but my code has precious few integer divides in the hot path. Still, even a multi-cycle divide implemented in microcode would be better than a subroutine.
Slashdot Mirror
They have talent in Microsoft, they have money, they have a market to leverage, yet time and time again he fails to marshal them.
Yes, don't you think this is excellent? Why interrupt him when he is busy doing such good for the human race?
The technical argument is as good (and the same) as the one supporting caching raid controllers.
And what makes you think there is a technical argument in support of caching raid controllers? Just asking.
It will double the momentum of the recoil, not the velocity.
You can't be serious.
p = mv
Tatoo it on your ass.

how many frames per second does it get in Crysis?
Only 60 FPS, but the screen resolution is 10,000,000 x 10,000,000 projected on the inside of a sphere
SGI hired a Microsoft exec much as Nokia did.

Intel will have to compete without its traditional legacy compatibility advantage?
Also without help from Microsoft which is still way too busy doing its duck with a broken wing act in the phone market to be of any use to Intel.
AMD had their chance but they always managed to screw things up
Or is it more like, AMD had their chance but Intel forstalled that in large part through illegal trustmaking activies.
people are pushing the ever loving crap out of these devices and IPC has been Intel's ball park for quite the long time
But do you really want a 450 watt power supply in your phone?

I hope they actually consult a physicist when they do that gun, the lack of recoil needs an explanation.

2. Avoid hiring any ex-Microsoft exec -
You will never know what are their intentions
Elop is one fine example
Strangely enough, Paul Maritz is a counterexample.
