unknown x
a friend of mine sent me this sms the other day biggest mystery of maths... 1000s of yrs hav passed ... millions of theorems derived... crores of formulas derived.... but still...."X" is unknown!! i thought i should give him a suitable reply when i thought for a while i realised that i also need to send a xmas greeting to this friend and connected both the needs my reply sms was this i thought 2k yrs ago X was shown by God to be his son Jesus. merry x mas. the connect was X being used to replace christ in christmas. how's that!!! a friend of mine Mr.Kak gave me the reference of wikipedia to the origin of use of X for christmas. from wikipedia i understand that X stands for chi the greek letter starting in christmas. i think i was over enthusiastic in blowing my own trumpet.
