Hydraulic fracturing is the propagation of fractures in a rock layer caused by the presence of a pressurized fluid. Some hydraulic fractures form naturally, as in the case of veins or dikes, and are a means by which gas and petroleum from source rocks may migrate to reservoir rocks. Induced hydraulic fracturing or hydrofracking, commonly known as fracking, is a technique used to release petroleum, natural gas (including shale gas, tight gas and coal seam gas), or other substances for extraction. This type of fracturing creates fractures from a wellbore drilled into reservoir rock formations.
Hydraulic fracturing has come under scrutiny internationally owing to concerns over possible chemical contamination of groundwater and air. Some countries have suspended or even banned it. The first use of hydraulic fracturing was in 1947, though the current fracking technique was first used in natural gas shales in the late 1990s in the Barnett Shale in Texas. The energy from the injection of a highly-pressurized fracking fluid creates new channels in the rock which can increase the extraction rates and ultimate recovery of fossil fuels.
William Sanford "Bill" Nye (born November 27, 1955), popularly known as Bill Nye the Science Guy, is an American science educator, comedian, television host, actor, mechanical engineer, and scientist. He is best known as the host of the Disney/PBS children's science show Bill Nye the Science Guy (1993–1998) and for his many subsequent appearances in popular media as a science educator.
William Sanford Nye was born in Washington, D.C., the son of Jacqueline (née Jenkins; c. 1920–2000), a codebreaker during World War II, and Edwin Darby "Ned" Nye (died 1997), also a World War II veteran whose experience in a Japanese prisoner of war camp led him to become a sundial enthusiast. Nye is a fourth-generation Washington, D.C. resident on his father's side of the family. After attending Lafayette Elementary and Alice Deal Junior High in the city, he was accepted to the private Sidwell Friends School on a partial scholarship, graduating in 1973. He studied mechanical engineering at Cornell University, where one of his professors was Carl Sagan, and graduated with a Bachelor of Science in 1977. He was awarded an honorary doctorate by The Johns Hopkins University in May 2008. In May 2011, Nye was awarded an Honorary Doctor of Science degree from Willamette University where he was the keynote speaker for that year's commencement exercises.
Mountains high
The wind blows
And I just follow
The fire's hot
Your eyes have blown
My skin's aflame
And heaven knows
Your hair's like ice
A smile that burns
Your eyes - the truth
See right through me
When you're around
I lose myself
A fire king like nothing else
And I feel alive when you're near me
And I cannot hide my tears
When you hold me
When you love me
It's like fire
And the world's aflame
I can feel it
Deep inside me
You're the fire king
The rain could fall
Alone and cold
The wind could blow
But you're life
Need none
You can face it all
Eyes so bright
A smile that burns
You see the truth
And no one love me
When you're around
I lose myself
A fire king
And no one else
And I feel alive when you're near me
And I cannot my tears
When you hold me
I feel (I feel)
Alive when you're near me
And I cannot hide my tears
When you hold me
When you love me
It's like fire
And the world's a flame
I can feel it
Deep inside me
