How many theoretical physicists does it take to change a light bulb?

In theory 11 - one for each dimension.

In practice 3 - One to hold, one to turn, and one to rebuttal the whole time. :-)

One to figure out if the problem is truly there or an anomaly of time and space.

Another to ponder the effects of light and dark on the human potential.

Yet another to calculate how many people it would take to rectify the problem, if it's really there.

Another one to argue and debate the existence of the problem with the last guy.

One more to figure out if the light expanded or imploded in it's last few moments of life.

And one more to make the passing custodian wonder why there are six scientists arguing the relativity of ComEd in the dark and prompt him to change the bulb himself.

It would blissfully take only one to screw the bulb in but a consensus of hundreds would have to be obtained to determine whether that bulb would light or not when the switch is thrown. Sadly that consensus would never be reached. They'll be arguing that outcome until God stops playing dice on St Nevercome's Day.

One. How many of you does it take to understand theoretical physics? Now THAT can't be done.

are they Polish theoretical physicists?..might need a calculator

none. They will need to bring an experimental physicist

11 because that's how many people are on the field when an

american football team is short their opponent for every action is

an equal and opposite reaction

It depends on the point of view of the observer.

3, one to change it, and the other two to debate if it is actually there

none, they wouth either sit in the dark and ponder the question or call the maintenance guy
