"Symmetry" is a song by Australian recording artist Gabriella Cilmi. It was released as the second single from her third studio album The Sting on 11 November 2013 on digital download format.
A music video was released on 17 September, it was directed by Tim Fox, the director of o Saris' 'The Addict' and Zico Chain's 'New Romantic'. The video features Cilmi and a long-haired actor in a space other-worldly atmosphere that reminds us of her Ten lead single On a Mission.
"Symmetry" was co-written by Tom Fuller, with whom she already worked with Sweeter In History. It is an enercig ballad that reminds us of her Defender, with a romantic side, that has been inspired by Cilmi's former relationship.
The website "Planet Music Reviews" described Symmetry as a "pop (song) with elements of rock. I found this to be infectious and it showed that she went back to her original style which featured on début album Lessons To Be Learned. Symmetry was a promising track and it is a definite for album #3 in my books."
In physics, a symmetry of a physical system is a physical or mathematical feature of the system (observed or intrinsic) that is preserved or remains unchanged under some transformation.
A family of particular transformations may be continuous (such as rotation of a circle) or discrete (e.g., reflection of a bilaterally symmetric figure, or rotation of a regular polygon). Continuous and discrete transformations give rise to corresponding types of symmetries. Continuous symmetries can be described by Lie groups while discrete symmetries are described by finite groups (see Symmetry group).
These two concepts, Lie and finite groups, are the foundation for the fundamental theories of modern physics. Symmetries are frequently amenable to mathematical formulations such as group representations and can, in addition, be exploited to simplify many problems.
Arguably the most important example of a symmetry in physics is that the speed of light has the same value in all frames of reference, which is known in mathematical terms as Poincare group, the symmetry group of special relativity. Another important example is the invariance of the form of physical laws under arbitrary differentiable coordinate transformations, which is an important idea in general relativity.
I'm caught in the symmetry of your mind
But I'm not happier than you
Did I really see you or was it a dream
Dreaming that it was seamless
Not a trace of wrong words
That we have spoken
Little did we know
No bigotry no tears shed
Oh if only you'd try to be polite
Thinking you were right
Only to find that you're unkind
But ironically you will always be
Belle of the ball at least to me
I'm caught in the symmetry of your mind
But I'm not happier than you
But my words are frail not audible
They do not even convince me
Perhaps they are untrue
Truly with you the worst is always true
I gave you all the benefits of all the doubts I had
Never hoped to be as benign as me
Funny how you always get through
But ironically you will always be
