Lots of different ways.  There just needs to be an established convention.  And you need to make sure that no confusion can arise.\n\nYou can write it in a YYYYMMDD format, so today would be 20061107.\n\nYou can also express it in number of days since a certain date.  For example, you could make January 1, year 1 A.D. equal Day 1 and count from there.

No.\nYou have to find cos(100) and then multiply it by 24\ncos(100) = -.1736

try "The Great War For Civilisation" by Robert Fisk.  You will need to go back further than 20 years too as the current problems are rooted in the decisions made after the first and second world wars.  This book covers other countries in the Middle East too.

Because 0-100 was the first century\n100-200 was the second century\nTherefore 1900 -2000 was the 20th century\n\nand 2000-2100 in the 21st century.

M + W + K = 100\n10M + 2.5W + .1K = 100\n\nYou need a third equation to be able to solve it.  Who your family members are doesn't change depending on what you need them to be.

American History Timeline:\n\nTimeline of the Twentieth Century\n\nLinks to History Timelnes\n\nYou haven't said what kind of timeline you are looking for. If these are not helpful, I suggest you use the phrase "20th Century" instead of 1900-2000 followed by the topic and lastly the word timeline. You are more likely to get a result that way.
