A friendship beyond QM
'...arguments on matters concerning physics never came in the way of friendship between Bohr and Einstein. They were both truly great, rising above differences in their scientific viewpoints. Bohr came to India around 1960, and i vividly recall a lecture he gave to a crowded audience in the TIFR, Bombay. Bohr was then over seventy, and he spoke about his longstanding debate with Einstein. He presented slide after slide of experimental apparatus visualized by Einstein and also himself in their various gedanken experiments. Bohr then went on to patiently explain how Einstein was in error. The sound system wasn't good and Bohr's accent wasn't easy to follow. Frankly, i did not understand one word of what Bohr said! And yet i sat there spellbound because Bohr had lectured as if the audience did not exist and as if there was Einstein sitting in front of him. In fact, when Bohr came to the end ,he did not exult in joy (since his arguments upheld quantum mechanics). Instead, he was in tears, unhappy perhaps about having won an argument against his dearest friend.'
Another one, by Abraham Pais:
'I began to grasp not only the thread of Bohr's arguments but also their purpose. Just as in many sports a player goes through warming up exercises before entering the arena, so Bohr would relive the struggles which it took before the content of quantum mechanics was understood and accepted. I can say that in Bohr's mind this struggle started all over every single day...Einstein appeared forever his leading spiritual partner- even after the latter's death he would argue with him as if Einstein were still alive.'

jokes jokes jokes!
Simple,he cut the guardian's knot!
2) A topologist wanted to buy a doughnut, but since it was not available, he brought a coffee cup!
3) What did Cantor order when he visited Saravana Bhavan?
Set dosai!
4) This is more of poetry than a joke:
The conjugate pair commute to another dimension, and in a field, exchange rings! The simple groups watch the operator perform the complex analysis, as the pair causally kiss and kill... of course,all this is a lie!!

Senti-mental me!
"When we both were young, Daniel Gallin and I collaborated on a number of mathematical projects. We rented a sunny studio in San Francisco and talked away the golden afternoons. It was those conversations that revealed to me not what mathematics was-that i thought i knew-but how it should be done. I will always treasure the memory of the days we spent together, when we thought that time would never end."
These beautiful lines reminded me of the days i spent with my friends' circle in hostel,"talking away the golden afternoons", and golden evenings too, gobbling down cups of coffee at chota canteen, or chips from ambani's shop! This post is dedicated to all those friends of mine!:)

The guilt of the chaotic butterfly!
The popular butterfly effect says that flapping of a butterfly's wings causes a hurricane on the far side of the globe!so is it that the butterfly is guilty of taking so many lives?i also thought of another question-what about its "karma" (i felt it would be fun to view this concept of karma i keep hearing every now and then in terms of this)?i shall address the first question briefly,but the second one i prefer leaving open for more comments!:D
Of course,it would be a mistake to conclude that the butterfly is solely responsible for the hurricane. It might take many many butterflies to flap their wings at certain conditions to obtain the essential statistical features to trigger the hurricane. These tiny disturbances is what is manifested as a hurricane. Its something like a contraption,if you would like to call it that way!
This is associated with the well known but widely misunderstood chaos theory. The butterfly effect is closely related to what are called strange attractors, the most famous of them being the lorentz attractor. They give an insight into the fact that chaotic systems can be predicted over a short span of time (of course,short here is relative, im not addresing that question since it depends on what we choose to be our system) but not in the long term. That is because our accuracy to predict the system's behavior gets lower and lower; however, the system remains on the same attractor.
Now to the second question- however small it is, the butterfly is still guilty of contributing to a hurricane. what consequence does it have on its karma? does doing an act "unkowingly" add to it? or is it that its contribution to a hurricane is a pre-programmed part of the pattern(im opening the option of a fatalistic approach since this is another topic that i have heard a lot about), and hence it is destined to do so?
Since my second question deviates from science, i thought i could also discuss another crazy thought that crossed my mind with respect to chaos. I came across the fact that moon's tides stabilize the earth against influences that would otherwise lead to chaotic motion,causing rapid shifts of climate in "Taming the Infinite" by Ian Stewart(an excellent book). That lead me to wonder how guilty Piccolo would have felt after destroying the moon with a single blast to stop Gohan from causing any destruction in his monster form in dragonball Z. Of course,the creators of the series did not allow anything to happen to the planet in spite of the missing moon!:D

FIDE world chess championship 2010
The world chess championship match (http://en.wikipedia.org/wiki/World_Chess_Championship) is on between Vaselin Topalov (http://en.wikipedia.org/wiki/Veselin_Topalov) and Vishy Anand (http://en.wikipedia.org/wiki/Viswanathan_Anand)...they have played five games now (as on 30th april 2010), and Vishy leads 3-2.
The first game was a shocker as Vishy,playing black, lost without much resistance to Topalov in Grunfeld defence.People attributed this to the delay in Vishy's arrival to Sofia (where the match is being held) because of the Eyjafjallajökull volcano.Also,there was this theory that he was 5 years older to Topalov,and that the age factor gave the latter an advantage.I do not disagree that age is an important factor,but modern chess has come a long way with players focussing on overall physical fitness.
Vishy bounced back strongly in the second with a convincing victory in Catalan,playing white.He had a strong passer on b7 by 41st move, and Topalov resigned in the 43rd.
The third was a draw in Slav,and the fourth was simply brilliant as Vishy sacrificed a knight to launch a strong kingside attack to seal a win.The fourth game was again Catalan,where Topalov tried hanging on to an extra pawn on his queenside and soon found himself in a bit of trouble when anand rang the warning bells with Ng4!
The fifth was Slav again,and the players repeated the 3rd game till the fifteenth move,where anand was the first to deviate with h5 instead of h6,which he played earlier.Certainly not a game for newbies thanks to its positional nature,this game reached a draw.
