What a coincidence; The New York Times of today (the Magazine section,
page 32) has description of the term factoid. Here is what they write:
.... The oid suffix, rooted in the Greek for "shape", creates a noun or
adjective meaning "similar but not the same; having the characteristics
of." A factoid, coined in 1973 by Norman Mailer, is an imagined or
simulated fact.
I am sorry of confusing the term "factoid" with the "experimental fact".
Tycho Brahe was a collector of experimental facts, not factoids. But I
think that a more profound confusion is possible when one is saying that
an "imagined fact" = "a simulated fact". A scientific simulation is not
the same thing as an artistic imagination (animation, etc.).

Physical reality does not have to agree with our ideas. But in physics
our ideas must agree with that reality. Otherwise it is not physics.
