		<description>&lt;p&gt;There is or never will be a message from god.faith is absolute without tangible proof.if you need proof, your faith is non existent or weak at best.Mother Theresa questioned her own faith at one time.It&#039;s not easy being green.&lt;/p&gt;

		<description>&lt;p&gt;Actually, there is a very good reason to calculate pi beyond 39 places:  Error compounding.  When calculating trajectories for say, simulating stellar bodies, one uses a discrete timestep simulation and the finer the timestep the better the accuracy / easier certain problems become (in general).  However, the finer the timestep the more calculations are involved.  The more calculations are involved, the more error is accrued (since the next calculation uses the previous as the basis) when an imprecise value of constants like pi are used.  (We won&#039;t even get into what happens when floating point is used...)&lt;/p&gt;

		<description>&lt;p&gt;Come on now. Only 4% of the planet uses a date format that puts the month before the day. Most of the rest of the world outside of North America uses day/month/year. Certainly, Albert (a European) would have done and would therefore have considered his birthday as 14.3 - hardly &quot;pi&quot; related at all!&lt;/p&gt;

		<description>&lt;p&gt;You may only need 39 digits to get such accuracy, but error propogation in many numerical algorithms often take 39 digits of accuracy, and output 0 digits of accuracy.&lt;/p&gt;

		<description>&lt;p&gt;Speaking of pie, may I suggest you check out Juliet Mae Spices (online); a truly great source for apple and pumpkin pie spices. You do not need to go 37 spaces to the right of the decimal point to find Juliet Mae spices are a great value.&lt;/p&gt;

		<description>&lt;p&gt;Pi Day is not the 14th of March, it&#039;s the 31st of April. The next great year for Pi is 2015 (31/4/15). Then 2159. Best year so far was 1592. You see the pattern?&lt;br&gt;&lt;br&gt;PS. Americans use a silly date system. Discuss.&lt;/p&gt;

		<description>&lt;p&gt;Well, obviously yo guys know alot... how about this? How many digits of pi would need to calculate the circumference of the known universe to a precision the radius of an atom?&lt;/p&gt;

		<description>&lt;p&gt;Actually there is a heck of a lot less holes in the creation theory than any other theory out there. Another thing is that people like Darwin went out to prove a theory with the preconcieved notion that God does not exist.  By the way, no God does not play dice :)&lt;/p&gt;

		<description>&lt;p&gt;Sure pi has lots of other uses, but the point of the article is that we dont need pi to 100 places in everyday maths. 22/7 is good enough, and easy to remember. As for the universe bit, if you had a circle the size of the universe, then 39 places would be accurate.&lt;/p&gt;
