I'm familiar with the usage of 'lemma' and 'corollary'; the first is a theorem used for the proof of a typically broader, more important result; the second is a consequence (usually immediate) of a previously proven result. These are both theorems, but it is more useful to call them by these terms.

However, I don't quite understand the special usage of 'proposition'. Why call something a proposition instead of a theorem?

This curve takes into account war, disease, natural disasters, etc. If you have taken statistics, you should be familiar with the bell curve. Heck, if you are or were ever a student you should be familiar with curves.

In a certain region of the country it is known from past experience that the probability of selecting an adult over 40 years of age with cancer is 0.05. If the probability of a doctor correctly diagnosing a person with cancer as having the disease is 0.78 and the probability of incorretly diagnosing a person without cancer as having the disease if 0.06. what is the probability that a person is diagnosed as having cancer?

my version :

the nature of god...
the god or gods are around all the time...
( with your mind)
if your reach out a god will reach out to touch you.
most of the time a god wouldent touch you if you dident reach out. ( with your mind) and soul
it can be one is open like this ...
but true belief makes you stronger.
if you did you would find most days the god in question is like the wind , The answers provided where progressions of happening ...
if you actualy ask a question the answer can be in words sometimes your own , you will suddenly reflect on something you already know .. this is the answer say thanks

A positively charged meteorite Zapyu (no such thing, but this is a thought experiment) is falling towards Earth. After it has reached a certain speed (say, v), God decides to show who's boss --- He switches off Zapyu's gravitational field (as God only can). Whap ! Zapyu's gravitational mass also goes to zero. Since Earth now exerts no pull on Zapyu, it continues to fall, but with uniform speed v. God smiles smugly at all who watch. .
Wait, though ! Along comes the Devil, who decides to show some muscle, just to keep his vote-bank intact. Whing ! He switches on a strong upward electric field to slow down/stop Zapyu's fall.

Now speak, O wise ones. Will the Devil succeed or won't he ? If he does, it means Zapyu still has inertial mass (since the external force retards its motion) although no gravitational mass, and the equivalence principle goes for a six. If he doesn't, Zapyu's i-mass has also vanished, the e-principle holds and both God and Einstein sigh in relief.
Well ?

We know that sound and visuals can be stored using audio/video recorders. Do we have any instruments using which odours/taste of substances can be stored/recorded?

do we have any mechanism by which we can say 1000 years down the line how todays "KFC chicken smelled like" or how "coke tasted like in 2006"?
