Reflecting Telescopes:

Reflecting Telescopes are used to view sky objects such as planets, the moon, star clusters, galaxies, nebulae, and multiple star systems.

Components:

Hollow Tube – Provides the structure of the telescope

Glass Lens – Allows source light into the tube

Parabolic Concave Mirror – Reflects source light to focal point

Secondary Flat Mirror – Reflects light at focal point to eyepiece

Eyepiece – Light and image is reflected here

Focuser – Adjusts the focus of the image at eyepiece

Refracting Telescopes:

Refracting telescopes are used to view images of the moon, planets, star clusters and general sky gazing. However, they tend to be smaller in aperture than other types so they are not as good for viewing fainter sky objects such as galaxies and nebulae.

Components:

Hollow Tube – Provides the structure of the telescope

Convex Objective Lens – Bends light source into the tube, and then magnifies

and focuses it at one point.

Eyepiece – The light focused then disperses through this lens

The Twin Keck Telescopes

The Twin Keck Telescopes

http://www2.keck.hawaii.edu:3636/realpublic/gen_info/kiosk/#telescopes

Situated upon the dormant volcano Mauna Kea in Hawaii, the twin Keck Telescopes are the largest reflecting telescopes in the world. The telescopes each have a primary mirror 10 meters in diameter and composed of 36 hexagonal segments that work in complete coordination to form a single piece of reflective glass. The telescopes were made possible by over $140 million funded by the W.M. Keck Foundation. These telescopes are reflection telescopes weighing about 270 tons a piece and are encased in massive domes. Each day, the dome must be chilled by massive air conditioners to prevent warping of the infrastructure due to temperature fluctuations. The telescopes in the domes are kept at below freezing temperatures and are used in shifts of 1-4 nights. Scientists use the Keck Telescopes to seek answers to questions such as:

Sayings

Lies and deceit bring only troubles and worries.

A good deed is always returned with ill.

A bit of generosity can change a life and bring happiness.

Shakespear

All the new technological advances we have today aid us in our lives. Imagine a time when nothing we take for granted today existed. Our lives would be more challenging and difficult. In Shakespeares England, during the 16th and 17th centuries, the lifestyle was very different from that of the 21st century. Superstitions, medicine, education, justice, and diet were all very different from what we have today. Because of the culture, science, and technology back then, life was very much more challenging than it is today.


Classicism

Classicism (sometimes referred to as neoclassicism) is the principles and aesthetic attitudes emphasizing form, simplicity, proportion, and emotional restraint based on the culture, art, and literature of ancient Greece and Rome. Classicism in literature is predominately inspired by antiquity and characterized by the faithful adherence to ancient aesthetic ideals rather than individual expression. Furthermore, classical poetry was written with an aura of pride and denotes the imitation of Greek and Latin themes [as well as] the imitation of Greek and Roman literary forms in composing works on any theme (137 Preminger) Either way, classical writers maintained a rationality and universality [in] their themes (139 Preminger). Notable English classical writers are John Dryden (1631-1700), Thomas Rymer (1641-1713), and Alexander Pope (1688-1744) (139 Preminger). Their poems were inherently conservative, prideful of the ancient ideals, and express distrust in innovation and change. In Essay on Criticsm, Alexander Pope describes the philosophy of classical poetry as:

Two levels of character, the Poet, the Host, the Miller, the Reeve

Two levels of character, the Poet, the Host, the Miller, the Reeve.
