1. William Shakespeare
Not from the stars do I my judgement pluck,
And yet methinks I have astronomy—
But not to tell of good or evil luck,
Of plagues, of dearths, or seasons' quality;
Nor can I fortune to brief minutes tell,
'Pointing to each his thunder, rain, and wind,
Or say with princes if it shall go well
By oft predict that I in heaven find.
But from thine eyes my knowledge I derive,
And, constant stars, in them I read such art
As truth and beauty shall together thrive
If from thy self to store thou wouldst convert;
Or else of thee this I prognosticate:
Thy end is truth's and beauty's doom and date.

2. William Wordsworth
NUNS fret not at their convent’s narrow room;
And hermits are contented with their cells;
And students with their pensive citadels;
Maids at the wheel, the weaver at his loom,
Sit blithe and happy; bees that soar for bloom, 5
High as the highest peak of Furness-fells,
Will murmur by the hour in foxglove bells:
In truth the prison, unto which we doom
Ourselves, no prison is: and hence for me,
In sundry moods, ’twas pastime to be bound 10
Within the Sonnet’s scanty plot of ground;
Pleased if some souls (for such there needs must be)
Who have felt the weight of too much liberty,
Should find brief solace there, as I have found.

3. Abraham Lincoln i/ˈ eɪbrəhæm ˈ lɪŋkən/ (February 12, 1809 – April 15, 1865) was the 16th
President of the United States, serving from March 1861 until his assassination in April 1865. He
successfully led his country through its greatest constitutional, military and moral crisis – the
American Civil War – preserving the Union while ending slavery, and promoting economic and
financial modernization. Reared in a poor family on the western frontier, Lincoln was mostly
self-educated. He became a country lawyer, a Whig Party leader, Illinois state legislator in the
1830s, and a one-term member of the United States House of Representatives in the 1840s.
After a series of debates in 1858 that gave national visibility to his opposition to the expansion
of slavery, Lincoln lost a Senate race to his arch-rival Stephen A. Douglas. Lincoln, a moderate
from a swing state, secured the Republican Party nomination. With almost no support in the
South he swept the North and was elected president in 1860. His election was the signal for
seven southern slave states to declare their secession from the Union and form the
Confederate States of America. The departure of the Southerners gave Lincoln's party firm
control of Congress, but no formula for compromise or reconciliation was found. And the war
came.
Early life
Main article: Early life and career of Abraham Lincoln
Abraham Lincoln was born February 12, 1809, the second child of Thomas Lincoln and Nancy
Lincoln (née Hanks), in a one-room log cabin on the Sinking Spring Farm in Hardin County,
Kentucky,[6] (now LaRue County). Lincoln's paternal grandfather and namesake, Abraham, had
moved his family from Virginia to Jefferson County, Kentucky,[7][8] where he was ambushed
and killed in an Indian raid in 1786, with his children, including Lincoln's father Thomas, looking
on.[8] Thomas was left to make his own way on the frontier.[9] Lincoln's mother, Nancy, was
the daughter of Lucy Hanks, and was born in what is now Mineral County, West Virginia, then
part of Virginia. Lucy moved with Nancy to Kentucky. Nancy Hanks married Thomas, who
became a respected citizen. He bought and sold several farms, including Knob Creek Farm. The
family attended a Separate Baptists church, which had high moral standards and opposed
alcohol, dancing, and slavery.[10] Thomas enjoyed considerable status in Kentucky—where he
sat on juries, appraised estates, served on country slave patrols, and guarded prisoners. By the
time his son Abraham was born, Thomas owned two 600-acre (240 ha) farms, several town lots,
livestock, and horses. He was among the richest men in the county.[7][11] However, in 1816,
Thomas lost all of his land in court cases because of faulty property titles.[12]

4. Eyepiece Lens: the lens at the top that you look through. They are usually 10X or 15X power.
Objective Lenses: Usually you will find 3 or 4 objective lenses on a microscope. They almost
always consist of 4X, 10X, 40X and 100X powers. When coupled with a 10X (most common) eyepiece
lens, we get total magnifications of 40X (4X times 10X), 100X , 400X and 1000X. To have good resolution
at 1000X, you will need a relatively sophisticated microscope with an Abbe condenser. The shortest lens
is the lowest power, the longest one is the lens with the greatest power. Lenses are color coded and if
built to DIN standards are interchangeable between microscopes. The high power objective lenses are
retractable (i.e. 40XR). This means that if they hit a slide, the end of the lens will push in (spring loaded)
thereby protecting the lens and the slide. All quality microscopes have achromatic, parcentered,
parfocal lenses.
