Love is something that brings us on these type of questions....bcoz most of us are in confusion...but according to me--love is about caring anyone we want..if anything happens to those we love seems that happend to us...it may be happiness,joy,sad....etc...connection of feelings iz not only love..as an example -if a man may be a leader does something good for his peoples or country then it's not his feelings connected with people's but that's also love..love for humanity.....samething is with others...someone loves his/her family;frnds;lifepartner;sometime it starts with attraction(boyfriend,girlfriend),nation, thing .........so we should love everything that's good for good people Love iz great....it is that thing that always spread happiness...it's a passion to keep and be happy and satisfied with life......so as someone blessed by god for a good life... .....Love is great.....and people who follow love are more great..so try loving......start loving..and get love get life..bcoz love iz life
In ancient China , values for π included (around 1 AD), √ 10 (100 AD, approximately ), and 142 / 45 (3rd century, approximately ).  Around 265 AD, the Wei Kingdom mathematician Liu Hui created a polygon-based iterative algorithm and used it with a 3,072-sided polygon to obtain a value of π of .   Liu later invented a faster method of calculating π and obtained a value of with a 96-sided polygon, by taking advantage of the fact that the differences in area of successive polygons form a geometric series with a factor of 4.  The Chinese mathematician Zu Chongzhi , around 480 AD, calculated that π ≈ 355 / 113 (a fraction that goes by the name Milü in Chinese), using Liu Hui's algorithm applied to a 12,288-sided polygon. With a correct value for its seven first decimal digits, this value of ... remained the most accurate approximation of π available for the next 800 years.
