But is it art?

[avgas]

I do enjoy a good mass debate

[Swoop]

Can't believe how poor MVs efforts to tart it up again this year were.

They are still recovering from the harley davidson ownership...
It'll probably take them years to get all the tassles and saddlebags out of the factory.

For example matter is destroyed to release the energy of a nuclear explosion. Also, when a body accelerates it's mass increases. At the speed of light it's mass becomes infinite. This is why the speed of light is an absolute limit for anythint that has mass.

The article you sited also has some factual errors. i.e:


A massless particle cannot add mass to the system.

Remember Newton's physics are incorrect when you take into consideration that something is traveling at speed of light, that's where Einstein came in.

I think you're confusing mass with momentum here... Acceleration causes your momentum to increase, not mass. You need an infinite amount of energy to move something at speed of light, mass doesn't change at all.

Rest mass doesn't change, but it is common in relativity to consider mass as having increased due to velocity.

(However, it's a little "out of fashion" to think of it this way).

Einstein does describe what happens at high speeds near the speed of light (nothing can travel at the speed of light). However, relativistic effects do occurr at low speeds but they can be discounted in most calculations. Also, quantum effects describe the destruction of matter due to radioactive decay. Anything that contains carbon will suffer from this. This is how carbon dating works (the ratio between C12 and C14).

No confusion. I have it on the authority of a qualified Nuclear and Particle Physicist (my wife) that mass does indeed increase as speed increases. This can be shown by E=mc2. This can be rewritten as m=E/C2. Therefore, as energy increases, so does mass.

Yes, you do need an infinite amount of energy to move something at speed of light. This is because of the increase in mass. If you plot mass vs speed you will find that it assymptotes towards infinity the closer you get to the speed of light. This is better explained thus:

Mass-Energy Equivalence

Another prediction of Special Relativity is that:

E = m c2

Since we now know that the speed of light is just a conversion factor for units, we can "read" this equation to say that mass and energy are equivalent.

We call the mass of an object when it is at rest relative to us its rest mass. If the object is moving relative to us its mass will be greater than its rest mass.

The relation between the mass m and the speed v of an object is shown below.

(nothing can travel at the speed of light).

What about light?

[swbarnett]

Now for the graph instead of just a link.

Indeed, you are correct. Although photons would be more accurate as visible light is only a small part of the electro-magnetic spectrum (all of whch is photons of varying wavelengths). This is the only exception.

Yeah I remember these in my early varsity days, given what attention I did pay. But what's not commonly known is that the E=mc2 doesn't use rest mass, it uses relative mass "m(rel)".

m(rel) is momentum to velocity. ie m(rel)=m(rest)/(1-v2/c2)

Hence for whatever mass as your velocity increases such that it's at speed of light then you have m(rest)/0=infinity.

Ask your wife to check if I'm right

One mans art is another mans junk.

That's brilliant, should do the same with my 250cc bike instead of selling it.

[gatch]

Back to the question asked..

I don't think it's art. With the big honda logo on the window. I think the man intends it to be art, but he is a cock and should stay away from functioning motorbikes.

What kind of a fuck wit takes a fully functioning bike and pulls it apart ? Why not take one with a fucked motor or that has 150,000km on it ?

And that other tosser with the 916 on his wall should be shot in the street, those things are art in motion, now it hangs motionless on his fuckin wall. I'd punch him right in the neck if I met him. Then stand on his cock for good measure.

Sorry, rant over..

Thanks. I probably should have posted something rather than just posting a link, and wiki link at that. As a first year eng student everything you've posted has been very helpful.

From the discussions I've had with her around this I believe what you say is correct.

So if I was traveling at speed of light my rest mass would remain at 80kgs however my relative mass (i.e. momentum) would be infinity kgs/m/s?
