I am imaging the gap between the floating point numbers represented in computer. Let’s compare an int and a float in 32 bits. The largest positive int is 2^16-1, and it is quite obvious that we cannot have that number, say, x and x-1 both represented in float. Furthermore, considering all the fractions we want to represent in the same 32 bits, the gap between two consecutive floating point numbers must be really large around x. It should be even bigger for larger numbers.

Sentiments
It is not the strength, but the duration of great sentiments that makes great men.

Oppenheimer
I watched a PBS show about Oppenheimer last night. Everybody who still has some faith in their government should watch it. (J. Robert Oppenheimer, just to be clear)

but each of us can do something better than others – it may be very few and very little, but we have it. That is our value.
