And an equation is the same whether it's written in red or green ink

The earth is but one country and mankind its citizens

I love speculating about solutions to problems in mathematics. I have no interest whatever in sudoku. But I do look at chess and bridge problems in newspapers. I find that relaxing.

All over India, all over the world, as the sun or the shadow of darkness moves from east to west, the call to prayer moves with it, and people kneel down in a wave to pray to God. Five waves each day - one for each namaaz - ripple across the globe from longitude to longitude. The component elements change direction, like iron filings near a magnet - towards the house of God in Mecca.

How rarely these few years, as work keeps up aloof,
Or fares, or one thing or another,
How we had days to spend under our parents' roof;
Myself, my sister, and my brother.

All five of us will die; to reckon from the past
This flesh and blood is unforgiving.
What's hard is that just one of us will be the last
To bear it all and go on living.

Even if a unity of faith is not possible, a unity of love is.
