sunsets and other wonders

I've been watching sunsets in my room almost everyday since I got here. And I noticed that the sun has been setting at different positions. It seems that it was moving towards the right as time has gone by.
And then I stumbled upon a documentary on BBC iPlayer,hosted by Professor Brian Cox, where he talks about time, and how it shapes the universe.
What I learnt -



This is a temple in Chankillo, Peru.
Each tower represents one month, you're looking at the oldest solar calender here!
This works for sunrises as well.

It's amazing how humans of different eras measure time. Positioning of shadows, flowing sand, gears etc etc.

So why can time be quantified? because it's one of the dimensions in this universe? What makes a dimension, a dimension?

According to wiki,

"In mathematics and physics, the dimension of a space or object is informally defined as the minimum number of coordinates needed to specify each point within it"

Following the song in Rent, Seasons of Love -

How do you measure love?

How to measure emotion? Why is it so difficult?

Everybody has their own different dimensions of emotions?

This is driving me crazy. As if my work hasn't been doing enough damage.
