umm actually their physics were against it at the time . because as you may know .. lift didnt exist to their knowlage at the time hence why 1000's of people died jumping off cliffs with feathers on their

Not only did they not have any principles saying that it was impossible, they also had evidence that it was possible. Unless you thought that birds only came into existance recently.

there is no acceleration for one instant at the very bottom.

Net acceleration anyway.

It is equal to 1/(infinity) seconds.

Quite true if you want to talk about the orbit as a simple harmonic motion!

yes...in the negative direction

Only if you define the positive direction as being 'Away from the sun', which seems silly. The earth's speed, ignoring tidal effects, friction and other such minor interactions, will remain fairly consistent throughout the year, or at least have a consistent cycle.

so you could have one radioactive or unstable nucleus (the element has a half life of 2 day or 24 hours) but yet you have no clue when it will really decay or emit radiation?

Indeed. Like when rolling a die, you may never get to 6.

I think not - well, not exactly. It is the act of opening the box and observing the contents which collapse the associated waveforms. I'm with ed84c on this, however, the cat can collapse its own waveform through self observation. I've discussed this with my own cat and she assures me she would notice if she were dead!

The cat can do what it likes, the superposition still exists from our point of view.

Remember, folks, that observing is any method of discovering whether the cat is living or dead. Find the center of mass of the box, shake it a bit, call in a psychic. These all count as 'observing' just as much as opening the box.

It has a horizontal velocity not a horizontal acceleration.

I. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.

It's stationary when it begins.

Therefore only vertical acceleration.

We were talking about it on the slope. You said that it didn't have a horizontal component of acceleration on the slope.

There's no horizontal accleration.

I think you mean the acceleration parallel to the incline and the acceleration at right angles to the incline

Resolve parallel to the ground, please. (The angle is there because I've just pasted it from another thread)

Impossible I hear you say!

Similarly, I hear you say that's impossible for the earth to orbit the sun, or for there to be indivisible particles. Put words into my mouth all you like, I have an exemplary understanding of basic mechanics.

and the eath is pulled back towards the sun again for yet another year gone by

That's an acceleration, is it not?

There's no horizontal accleration.

If there's no horizontal acceleration, how does it move down the slope?

surely it'd be because the ball is gaining acceleration from the force of gravity as it goes down the slope, once it stops going down it stops having the acceleration from gravity (and the hill) and therefore its not accelerating as fast so will stop in a shorter distance.

What?

Can you clarify the question?

I suspect it's because of the inelastic collision with the ground, but can't be sure that's the answer.

This means that the constructs of Einstein's Relativity theory don't include randomness and therefore are at odds with those of QM.

This doesn't matter in the slightest for Special Relativity. It matters for General Relativity, but that's not what you're talking about.

(a) Schroedinger was trying to point out the absurdity of applying QM to the world in which cats live

Or, stated more generally, the absurdity of applying QM to macroscopic events.

Isn't it possible to view everything in the universe as relative to the earth? Like the sun going around the earth? I'm pretty sure there is a fatal flaw to my idea, but I just can't find it...

The earth is accelerating. The sun is not (in this little system anyway).

None and never.

OK OK OK Wate a minut here . Im going to be the first persion to invent the machine of doom . and mine works at 128% . and for all you tards out there 64%, 50 % being balanced .

I really have no idea what this means.

no they are not related;

 

magnetic fields (from magnets)' date='

electrical currents (from batteries) &

electromagnetic spectrum (EM spec. like light etc)

 

are not really related...[/quote']

 

Except that magnetic and electrical fields use photons as the exchange particle.

 

Can you, for example, convert radio waves to visible light? Or could you possibly piggyback these things, like by (ignore practical uses, just can this be done) putting light waves on with the radio waves in order to make the waves visible?

 

Changing the wavelength can be done (doppler shift, for example). And you can't really piggyback radio and visable light, because visable light doesn't have the properties of the radio wave that let it be transmitted for the distances it is.

Whatever it is, it doesn't connect with Quantum Mechanical Theory.

It doesn't need to. It works perfectly alongside it.

So it's a pretty incomplete theory or description.

Only in that it doesn't describe everything, but then it's not supposed to. Is Quantum Mechanics any less useful because it doesn't describe how creatures evolve?

The ruler represents the rest frame of y.

whilst pc2700 still runs fine, it is slowly be over taken by the superior pc3200, if you were buying a new PC i'd greatly recommend a pc3200 as the 2700 will soon become out of date.

I think you mean that it is 'being replaced as the acceptable minimum', rather than 'being over taken'. I would definitely recommend 3200, but 2700 will cause fewer problems than cutting corners on CPU/MB.

i've got the GeForce 4 MX 420... that was about £30 (UK) about 2 years ago, and it still plays halo1 on max graphics smoothly!!!!

The Halo 1 problems depended on the card; for example, whilst the Radeon 9700 Pro is many times more powerful than (say) the Geforce 4400, the latter runs Halo 1 much better than the former. It's Gearbox's fault, they made a terrible conversion.

(that includes; halo1, need for speed underground 2, jedi academy, freelancer, GTA: vice city & toca race driver, those are recent ones i've played)

You do realise that, by and large, those are either running on 5 year old engines or are conversions of games running on 5 year old consoles? (Give or take a bit for sentence symmetry).

and i doubt ur gf fx 5500 will let u play HL2, Halo 2, or doom3 with bearable frame rates

Half Life 2 and Doom 3 run perfectly happily on my laptop, which has a lesser graphics card. The 5500 is actually a reasonably good card, it just wasn't cost effective compared to the radeon 9800 pro.

And if Halo 1 is anything to go by, not even SLI'd 6800's would do the job.

For the upgrades, you're not going to find them particularly cheaply. The best way to go, at the moment, is propably a Sempron 3100+, Socket 754 Motherboard and a stick of DDR2700/3200.

How could anyone have a losing position about their opinion[/u'].

You appear to be confused. If people say 'I believe in god', I don't say 'lol ure stupid, god doesn't exist', only if they make empirically refutable or logically incorrect statements do I argue.
