Science to record way of thinking about 1001 (12)
I believe the answer is:
epidemiology
'science' is the definition.
(epidemiology is a kind of science)
'record way of thinking about 1001' is the wordplay.
'record' becomes 'EP' (abbreviation for extended play record).
'way of thinking' becomes 'ideology' (I can't explain this - if you can you should believe this answer much more).
'about' indicates putting letters inside.
'i00i' becomes 'mi' (I've seen this in other clues).
'ideology' going around 'mi' is 'idemiology'.
'ep'+'idemiology'='EPIDEMIOLOGY'
'to' acts as a link.
Can you help me to learn more?
(Another definition for epidemiology that I've seen is " Study of the incidence and distribution of diseases".)
