A vague lyrics

Come up to meet you, tell you I'm sorry
You don't know how lovely you are

I had to find you
Tell you I need you
Tell you I set you apart

Tell me your secrets
And ask me your questions
Oh, let's go back to the start

Running in circles
Coming up tails
Heads on a science apart 

Nobody said it was easy
It's such a shame for us to part
Nobody said it was easy
No one ever said it would be this hard

Oh, take me back to the start

I was just guessing
At numbers and figures
Pulling the puzzles apart



What does "Heads on a science apart " mean? (ArtistColdplay)

(The overall message is that the speaker loves someone, but things aren't going well. He is running in circles, not achieving his aim of winning her heart. He bet on tails to get her, but the coin came up heads. He wishes he could turn back time and start over.)
