(1) El coneixement científic

"We are a way for the Cosmos to know itself."
Carl Sagan
 
La ciència és una forma de coneixement d'una realitat que de tant complexa desafia l'intel·lecte humà (sobretot si volem comprendre la vida, o pitjor encara, la ment). 
Tant l'art com la ciència representen l'esforç humà per ajudar a "fer visible allò invisible", tal com deia Paul Klee.

Science is real
From the Big Bang to DNA
Science is real
From evolution to the Milky Way
I like the stories
About angels, unicorns and elves
Now I like those stories
As much as anybody else
But when I'm seeking knowledge
Either simple or abstract
The facts are with science
The facts are with science

Science is real
Science is real
Science is real

Science is real
From anatomy to geology
Science is real
From astrophysics to biology
A scientific theory
Isn't just a hunch or guess
It's more like a question
That's been put through a lot of tests
And when a theory emerges
Consistent with the facts
The proof is with science
The truth is with science

Science is real
Science is real
Science is real
