Oscillation is the repetitive variation, typically in time, of some measure about a central value (often a point of equilibrium) or between two or more different states. Familiar examples include a swinging pendulum and AC power. The term vibration is sometimes used more narrowly to mean a mechanical oscillation but sometimes is used to be synonymous with "oscillation". Oscillations occur not only in physical systems but also in biological systems and in human society.
The simplest mechanical oscillating system is a mass attached to a linear spring subject to no other forces. Such a system may be approximated on an air table or ice surface. The system is in an equilibrium state when the spring is static. If the system is displaced from the equilibrium, there is a net restoring force on the mass, tending to bring it back to equilibrium. However, in moving the mass back to the equilibrium position, it has acquired momentum which keeps it moving beyond that position, establishing a new restoring force in the opposite sense. If a constant force such as gravity is added to the system, the point of equilibrium is shifted. The time taken for an oscillation to occur is often referred to as the oscillatory period.
Everything, it's so quiet here
Seasons last, more than thousand years
Suddenly my vision is clear,
consciousness into clarity
I can hear echoes from the sea
overwhelmed by tranquility
Radiance unfolds gradually,
every wound now begins to heal
Take on my burden, shake of my head
Chained by what I understand, won't let me grow
New found sight opens up for each
step into similarity
Void is all coming into reach,
mistakable familiarity
Take on my burden, shake of my head
Chained by what I understand, won't let me grow
Lay down my burden, take all my years away
Release me within emptiness and make me whole
There is a desire, there's a need of finding faith,
I decide by painting it all in grey
Inner transformation turns a weakness to a strength,
through the times the spirit will remain
Tethered by restrictions of the way to be aware,
all is gone the hindrance will fade away
Fundamentals separate transcending into where
time that flows is neither night nor day
Every piece that we retrieve from covering our eyes,
dawns on us we cannot leave with everything inside
I will reach my hand and try to open up the sky,
Do you know how it feels to be standing
Alone, with the weight of the world
Pressing down on you hard.
On chance to choke the pain gained,
By the things that you say, by
The games that you play.
From this moment I stand amazed, the
Question still remains. How you choose
To behave, what you make of your lifetime.
Let those feelings leave, I know that life's
Been tough. Be aware of what you've got.
Stay, stay with me, take me home
Don't let me go. Stay, stay here with
Me, where our souls will be free.
Lay down your principles and pray to your
God of emptiness, like a last stroke of
Consciousness, an attempt to be brave
And to reach expectations.
Your time has come, cherish all your loved
Ones in this bleak hour. Cause I know
They'll be leaving you one by one.
When the darkest clouds gone by
