'Standing Still' Alfred is still moving. V=c always. Also, with respect to whom is Albert standing still?

Sure you can(if it were possible to accelerate mass to c in one of the spatial dimensions). The 4-vector velocity is c. Changing your speed in one dimension changes it in all the rest.

Or you could just explode it while it's up there. EDIT: Mandatory cavity searches(with an optional prostate massage) for all passengers on international flights?

I guess you have a point there. Where would you place it on the fail spectrum?

Ummm, mainly that it's a fail so epic it's almost a win.

On Christmas, a man attempted an act of terrorism on a flight from Amsterdam to Detroit. His explosive device failed to detonate properly and the assailant succeeded in only harming himself. He was treated for second and third degree burns. http://www.cnn.com/video/?/video/crime/2009/12/26/nr.bergen.interview.cnn

Graphs like that are how we can graphically find velocities, etc(although time is usually the x-axis).

I just got Jesus: Apocalyptic Prophet of the New Millennium by Ehrman, and I'm going to start reading that today.

It's not exactly waste heat if you use it to warm the ship!

Not exactly. The cooling towers(or ocean for ships and submarines) are used as a heat sink in the steam system. The cooling of the reactor is done by generating steam in the secondary system. A nuclear propulsion system for a spacecraft wouldn't need that. The primary system could heat the gasses directly and expel them through a nozzle.

Each of an aircraft carrier's rectors(they all have 2, except for the Enterprise which has several submarine reactors) are indeed quite large. The reactor itself is 3 stories tall, then you have the primary system whose pumps are as big as submarine reactors. Then, you have the steam system(which is quite large-it's the rest of the heat cycle). On a carrier, they take up the space directly under the mess decks. Although, if we were just going to use them for just electrical power(or, in the case of the spacecraft, heating a gas), they could be considerably smaller. Also, submarines aren't terribly large. A submarine reactor is only like 12 feet across(but then you have the rest of the systems).

How so? edit: y=x^2 is infinite. Do you seriously claim that it has no shape?

Was that really necessary?

[21:15] <mooeypoo> it's salad WITH alfalfa [21:16] <Sylar> you didn't burn down the clubhouse, did you?

That's a great example of circular reasoning. Thank you.

Awfully close to force and momentum, though.

Didn't we already do this thread?

Festivus for the rest of us!

I'm still not seeing what that has to do with this thread.

How does that relate to the thread?

The situations aren't analogous since the laws requiring seatbelts/airbags and car insurance are conditional; they only apply if you decide to purchase/operate a motor vehicle. One could walk or ride a bicycle and avoid such things. However, the proposed law has no such opt-out sans suicide.

Linear velocity of which part? It's different at each point along the radius.

Not necessarily. I can have faith that the moon is made of cheese, but that doesn't make it out of bounds for the scientific method to explain whether or not the moon is made of cheese. To which matter of faith are you referring?

I'm not seeing what that really has to do with anything. It's a common claim that seems to be completely false.

They're not forcing you to buy cars or drive.
