A quick puzzle

Two students independently come to the library every day after dinner between 7pm and 9pm. Each stays for exactly one hour and then leaves. At any night, what is the probability that they met? (meaning that both were in the library at the same time even if for a very short while)

It came down today

To test out what is happening after the sky high heart rate yesterday, I tried something different today. Put in a warm up mile first. And then put in a faster than normal for me 5K run. After that, another one mile to cool down. The 5K was in 26 mins 40 seconds (at my normal pace, it would take closer to 30 minutes). It was nice and cool 63 degrees.

The heart rate readings today was closer to what I would expect. Highest was 183. It is still higher than what I would think (170 is what I was thinking it would be). But I was also monitoring my lungs. At no point did I feel I was struggling to take in enough oxygen. I will have to monitor a few more days to see if the heart rate is unreasonably high.

Deep thoughts

Last night, I was listening to Ataullah Khan’s rendition of “Idhar Zindagi Ka Janaza Uthega”. It is a beautiful poem written from the point of view of the man who realizes that the lady he loves is getting married to somebody else that night.

And I realized that most of the ghazals and qawwalis (or a large fraction of them at least) are about unrequited love.

In the Western world, it happens differently:
Man loves woman.
Woman does not return the love.
Man moves on to next woman.

But from the subcontinent I come from, it is like:
Man loves woman.
Woman does not return the love.
Man sits down to write a poem!!

Basketball throws: a rather intriguing puzzle

I had run into this problem long time back. I ran into it again last week. Thought will post it. See if you can solve it without using Google to find the answer. If not, then Google it – pretty interesting, huh? (I will post the answer later).

A basketball player keeps track of his throws for a full calendar year. He, of course, misses a few shots and succeeds with a few more. He missed the very first shot of the year. But he ended the year with 83% successful shots. You have to prove that there had to be a point where is success rate was exactly 75%.

Hint: this is not necessarily true for any number – e.g. 60%. But it is always true for 75%.

In fact, can you guess what are the other % (other than 75%) for which this is also true?
