Little Lamb, who made thee?
Dost thou know who made thee?
Gave thee life, and bid thee feed,
By the stream and o'er the mead;
Gave thee clothing of delight,
Softest clothing, woolly, bright;
Gave thee such a tender voice,
Making all the vales rejoice?
Little Lamb, who made thee?
Dost thou know who made thee?
Little Lamb, I'll tell thee,
Little Lamb, I'll tell thee.
He is called by thy name,
For He calls Himself a Lamb.
He is meek, and He is mild;
He became a little child.
I a child, and thou a lamb,
We are called by His name.
Little Lamb, God bless thee!
Little Lamb, God bless thee!
The Tyger
From Wikipedia, the free encyclopedia
"The Tyger" is a poem by the English poet William Blake. It was published as part of his collection Songs of Experience in 1794. It is one of Blake's best known and most analyzed poems. The Cambridge Companion to William Blake (2003) calls it "the most anthologized poem in English."[1]
Most modern anthologies maintain Blake's choice of the archaic spelling "tyger". It was already "slightly archaic"[2] when he wrote the poem, he spelled it as "tiger" elsewhere,[1] and many of his poetic effects "depended on subtle differences of punctuation and of spelling."[3] Thus, his choice of "tyger" has usually been interpreted as being for effect, perhaps to render an "exotic or alien quality of the beast",[4] or because it's not really about a "tiger" at all, but a metaphor.[1]
The Tyger is the sister poem to The Lamb (from Songs of Innocence). The Lamb is a reflection on similar ideas from a different perspective.

In mineralogy, diamond (from the ancient Greek ἀδάμας – adámas "unbreakable") is an allotrope of carbon, where the carbon atoms are arranged in a variation of the face-centered cubic crystal structure called a diamond lattice. Diamond is less stable than graphite, but the conversion rate from diamond to graphite is negligible at ambient conditions. Diamond is renowned as a material with superlative physical qualities, most of which originate from the strong covalent bonding between its atoms. In particular, diamond has the highest hardness and thermal conductivity of any bulk material. Those properties determine the major industrial application of diamond in cutting and polishing tools.
Diamond has remarkable optical characteristics. Because of its extremely rigid lattice, it can be contaminated by very few types of impurities, such as boron and nitrogen. Combined with wide transparency, this results in the clear, colorless appearance of most natural diamonds. Small amounts of defects or impurities (about one per million of lattice atoms) color diamond blue (boron), yellow (nitrogen), brown (lattice defects), green, purple, pink, orange or red. Diamond also has relatively high optical dispersion, that is ability to disperse light of different colors, which results in its characteristic luster. Excellent optical and mechanical properties, combined with efficient marketing, make diamond the most popular gemstone.
Most natural diamonds are formed at high-pressure high-temperature conditions existing at depths of 140 to 190 kilometers (87 to 120 mi) in the Earth mantle. Carbon-containing minerals provide the carbon source, and the growth occurs over periods from 1 billion to 3.3 billion years (25% to 75% of the age of the Earth). Diamonds are brought close to the Earth surface through deep volcanic eruptions by a magma, which cools into igneous rocks known as kimberlites and lamproites. Diamonds can also be produced synthetically in a high-pressure high-temperature process which approximately simulates the conditions in the Earth mantle. An alternative, and completely different growth technique is chemical vapor deposition. Several non-diamond materials, which include cubic zirconia and silicon carbide and are often called diamond simulants, resemble diamond in appearance and many properties. Special gemological techniques have been specially developed to distinguish natural and synthetic diamonds and diamond simulants.
Forever Young - Alphaville
Let's dance in style, let's dance for a while
Heaven can wait, we're only watching the skies
Hoping for the best but expecting the worst
Are you going to drop the bomb or not
Let us die young or let us live forever
We don't have the power but we never say never
Sitting in a sandpit, life is a short trip
The music's for the sad men
Can you imagine when this race is won
Turn our golden faces into the sun
Praising our leaders, we're getting in tune
The music's played by the madmen
CHORUS:
Forever young, I want to be forever young
Do you really want to live forever
Forever -- and ever
Some are like water, some are like the heat
Some are a melody and some are the beat
Sooner or later, they all will be gone
Why don't they stay young?
It's so hard to get old without a cause
I don't want to perish like a fading horse
Youth's like diamonds in the sun
And diamonds are forever
So many adventures couldn't happen today
So many songs we forgot to play
So many dreams swinging out of the blue
We'll let them come true
CHORUS
Forever young...
