Quote:teliotI get it, the 355-th day out of 365 days in the calendar year. Nice.

Nice yourself. I didn't get the reference myself, but was afraid I would look stupid if I asked about it.

Quote:teliotThat was my research area as well when I was a professor. Not many of us. At any rate, check out 355/113.

One of the things he noted was that he reviews papers (for journals) from only about 4-5 other academics that he knows personally, and only they are asked to review his papers, because that's pretty much the number of people in that particular sub-subfield.

I like the new fraction.

One time I submitted a paper and the referee called me and said he had been working on the same thing and had proved the same main theorem and was writing it up. I invited him to be a co-author. I then called the editor of the journal and informed him that the reviewer called me so he wouldn't be surprised that the person was added to the paper. What can you do?Quote:harvson3One of the things he noted was that he reviews papers (for journals) from only about 4-5 other academics that he knows personally, and only they are asked to review his papers, because that's pretty much the number of people in that particular sub-subfield.

I like the new fraction.

The fractions 22/7 and 355/113 come from the convergents in the continued fraction expansion of pi. The next best fraction after 355/113 is 103993/33102. When I was teaching programming at UCSB, I used to give a programming homework assignment to figure out these convergents by brute force.

I first saw 355/113 as an approximation of pi as part of a sample problem in the instruction manual for an HP35 calculator I bought back in 1973. The sample problems were for practice in using the RPN data entry system.Quote:harvson3I like the new fraction.

The problem suggested an easy way to remember this fraction if it is written as a long division problem (hope the notation looks right to everyone). They said to just write the first three odd digits twice each and separate them with the division symbol, like:

113√355

Quote:teliotThe next best fraction after 355/113 is 103993/33102.

355/113 wins, in my opinion, since it's 7 figures of accuracy in only 6 digits, is easy to remember, and fast to key.

103993/33102 is 10 figures accuracy in 11 digits - you do better to punch in 3.1415926535.

Quote:andysifQuote:rudeboyoiQuote:AcesAndEightsThis is my issue with calling this the "Pi day of the century." US date formatting is just plain wrong. There is an international standard, ISO 8601, that describes an unambiguous date format that is preferable to use. So yesterday was 2015-03-14.

Both 2015-3-14 and 14-3-2015 make more sense than the way we do it. From largest to smallest or smallest to largest.

anyone know the actual rationale behind this MM-DD-YY format? Even when you are saying it verbally, it should have been "1st" of "MAY", "2015"

Verbally you may also say "May 1st, 2015"

May your day be full of the joy and beauty of math!
