breaking the speed of light article on howstuffworks.com

a photon is defined as massless, but can you say it has volume?
 
i suppose it doesn't literally take up space, but it has a size right?

lol! windpipe particle... I should have known that, it comes from
trachea.

Traveling has one L, not 2. That I'm pretty sure of.

Depends where you come from.

If I was 41, I'd understand calculus, wouldn't I?

E=MC^2-GammaMV is the full equation. Gamma is proportional to how fast
you are going. It effects length contraction, time dilation, and
apparent mass. Basically, by looking at the equations, as you get
closer and closer to the speed of light, you're apparent mass gets
larger and larger with your mass equalling infinity at the speed of
light. Hence it would take an infinite amount of energy for you to get
to the speed of light. Photons get around this by being massless.

Hmmmm... but photons have energy. How so if no mass ?


Isn't the wave / particle debate fun ?

Well, if matter had to have mass to have energy, then what would energy
really be? A photon is not matter, it's pure energy.

I have always wondered, though, what the link is between light as a
particle and light as a wave.
 
For that matter, all waves can be described as particles

It is actually incorrect that we refer to photons as particles, as the
definition of particle in qed is "A subatomic object with a definite
mass and charge."

I think you do. You are wise in ways that take "mellowing time" ;-)

I love to cook with wine. Sometimes I even put it in the food.
 
How does it violate conservation of energy? The energy is still in the
system (the universe) just in another form.
 
My quantum mechanics teacher would probably break down laughing if he
saw that test.

What they really wanted was a circuit that made two pulses that partly
overlapped. They didn't really want to have to provide the "trigger"
input.

Was the other signal called the "latch", by chance?

Actually no.

IIRC it was called gate.

"trigger" controlled the current in a coil and "gate" controled the
sampling of the ADC circuits. Both were mis-named for what they really
did.

Ah, I wuz just wondering if you fell into the "wonders" of LSSD design.

I've heard this story that might make you feel better. Einstein was
once told that he was probably one of three people in the world who
understood his Theory of Special Relativity. His reply, "Really, who's
the third?"
 
No, I am really 14. I'm serious. On my birth certificate, I was born
December 4th 1990. I'm no genius either, I just have an enormously huge
obsession with science.
 
"> Light being pure energy "w/o" mass, it has to be the fastest.

Conclusion: to travel beyond the speed of light, one must be able to
either:
a) warp space

It's already warped.


b) stop time

Reverse time."

That's basically what I said earlier
 
Also, what exactly would be the point in saying I'm 14 if I was 41?
That wouldn't benefit me in any way.
 
I have real player, but the lectures aren't working. Maybe it's because
I'm on the windows 98. I'll try again later on the better computer.
