Pure mathematics is no longer a game for the young and restless only. Thanks to Chinese American Dr. Zhang Yitang's daring effort at raising the bar for 'bounded gap of prime numbers' from two to 70 millions, hence start the race towards solving 'Twin Prime Conjecture'
I am so pleased to watch this most recent coverage for Chinese audience from reporter of Voice of America. I've met most of Chinese folks in that interview.
I have been writing about inspirations Dr Zhang has inadverdently generated by his publication at Annuals of Mathematics. I read many coverage about this great excitement in pure mathematics world. I am particularly like this reader's comment quoted below. It goes back to my own thinking 'What is mathematics, really'. Once a maths lover, always a maths lover. Once a warrior, always a warrior. Life is beauty and terror. Mathematicians must have terrifying moments, that what millions see as self evident, need no proof, he has to take on the challenge to provide a mathematical proof without any funding from world government but private institution like Princeton Advanced Study.
"When there are possibly a million approaches towards solving a problem, and the feasibility of each approach is verifiable in polynomial time, this problem is called NP-HARD. When a prophet tells you that one particular approach is doable, then everybody can solve this problem in polynomial time.
When there are a million conjectures, and the provability of each conjecture requires indefinite time to know, this family of conjectures is called UNDECIDABLE. When a prophet tells you that one particular conjecture (e.g. bounded gaps between primes) is doable with contemporary techniques (modification of GPY), then a lot mathematicians, Tao for instance, would stop their current work and prove the conjecture “within months of each other”. I think you shouldn’t call this “a complete coincidence”.
What I do at my workplace is no pure mathematics nor rocket science. But I appreciate my own work, even when others have no need or no desire to pay attention to those details I spent majority of my time re-work out many inherited 'lousy' programming procedures. Here is an example, re-worded for this forum's liberal-minded readers:
A basic SQL problem:
if i have a result set, say:
CREATE OR REPLACE PROCEDURE DEL_OFOFFLINE_OLDMSG AS
V_max ofHolyPresence.Offlinedate%type := NULL
delete from ofoffHolyline
where creationdate older than ( select max(AdamIsBorn) from ofoffHolyline ) - ChristResurrect;
DISCLAIMER: THIS IS NOT A GENOCIDE PROCEDURE BUT PURIFYING FOR THE SAKE OF THIS PLANET TREES.
Since there can easily be many millions of records in my result set, current implementation is VERY inefficient at dealing with 'batch' deletion as it attempts to go through an INNER loop and joining two tables and sort messages that belong to one user. I have no control over chained blocks which might cause condition at any unspecific time when one out of thousands users might NOT be able to get messages delivered to him in real time when the job is in the run, how can I declare a curse/pointer to delete, let's say, 100 records at a time, regardless of what religious holy book it belongs to?
