Invisibility

Invisibility is the state of an object that cannot be seen. An object in this state is said to be invisible (literally, "not visible"). The term is often used in fantasy/science fiction, where objects cannot be seen by magical or technological means; however, its effects can also be demonstrated in the real world, particularly in physics and perceptual psychology classes.

Since objects can be seen by light in the visible spectrum from a source reflecting off their surfaces and hitting the viewer's eye, the most natural form of invisibility (whether real or fictional) is an object that neither reflects nor absorbs light (that is, it allows light to pass through it). This is known as transparency, and is seen in many naturally occurring materials (although no naturally occurring material is 100% transparent).

Invisibility perception depends on several optical and visual factors. For example, invisibility depends on the eyes of the observer and/or the instruments used. Thus an object can be classified as "invisible to" a person, animal, instrument, etc. In research on sensorial perception it has been shown that invisibility is perceived in cycles.

Track listings and formats

Invisible (Skylar Grey song)

"Invisible" is the debut single by American recording artist Skylar Grey. It was officially first released on iTunes on August 9, 2011. She performed the track along with various other songs on her upcoming studio album at The Glass House on July 31, 2011, and the song earned placement in the official trailer for the Madonna-directed film W./E..

Composition

Grey comments on her writing process for "Invisible" by saying "Before I started writing this album, I felt like I had lost control of my life and didn't know who I was anymore. I needed to ground myself so I decided to spend some time in solitude, and in the process discovered my inner super hero. The album tells that story starting with 'Invisible', which is how I used to feel."

Critical reception

Popcrush rated the song a four out of five stars and commented positively on the song's emotion and feel by saying "her song is an ode to feeling alone in a crowded room and feeling like no one can see the real you. The song addresses the notion of image, and the battle between the real you vs. the you that people see. It’s weighty subject matter encased in a pop song, with the lyrics surrounded by beats are light and airy."Billboard positively received the track and called it a "gorgeous, vulnerable opening statement that stretches her talent for crafting quick melodies over a fully formed pop track. "Invisible" sheds light on Skylar's own compelling persona."
