How long should we give string 'theory' to produce falsifiable predictions before we consign it to the 'interesting but not especially helpful' category of hypotheses?

all those years ago they thought the world was flat, even some great minds , so does it stand to reason that all the new theorys we read about are an absolute mile out and all the self important people out there are so wrong that future civiliations will use there views and ideas as sources of primative world comedy?. what would turn the worlds head towards space and astronomy other than finding et and all that other sci fi stufff?

of 2.95 cm is dropped on its edge onto a horizontal surface. The coin starts out with an initial angular speed of 12.1 rad/s and rolls in a striaght line without slipping.

If the rotation slows with an angular deceleration of magnitude 2.29 rad /s^2, how far does the coin roll before coming to rest (in units of m)?

If an alumnium sheet is held between the poles of a large bar magnet, it requires some force to pull it out of the magnetic field even though Al is not ferromagnetic and does not touch the poles.
Why?

(I was thinking thatmovement of the metal in a magnetic field induces an emf in theopposite direction...Yes? No?)

My question is:

Whenever I start to date someone that I REALLY like, I lose my appetite and become full very quickly from eating. Why does my body do that? What chemical is produced in the body when you are attracted to someone that would change eating habits?? I'm really curious. Please don't say that it is nerves because I don't get nervous around this person. Also, don't say that girls are embarrassed of eating in front of men because that's not true either. I want to know the CHEMICALS that are being produced when you are "in love."
