I don’t like how this suggests that the worth of a woman is based on her looks. Women have much more worth than that.
A typical DSL line runs by normal insulated copper cables, the data is transfered as electricity pulses, the cable then connects to your wireless router, and is transmitted to a receiver on your computer, giving you the internet.
A Fiber-optics cable has extremely thin strings of glass (each about the size of a human hair) inside the cable, and a laser that blinks millions of times a second is used to transfer the data. As the glass in the cable bends, the light is also bent. At each end there is a device that receives the data converts it to the traditional electrical pulses and then that is sent to the router the same as above.
Now to be honest the speeds you can get through satellite are not the speeds that you can get with DSL, Cable, nor the newer Fiber Optics.
In context of Binoculars, Telescopes and Microscopes the lens where you put your eyes to see an object is knowns as Eye Piece and The lens which is towards the object is known as Objective lens. Generally in Diameter of Objective Lens is greater than Eye Piece in order to gather more light in Binoculars and Telescopes and it's focal length is also more than eye piece.

hey bro – do you know if these Joe M. clips from a series that i could check out? i like the guard offense and pass counters.
“awesome! if you follow the path from the road to stonegenge, the scene changes (clouds and lighting change) the guard might have stopped them at first, then let them proceed (or they just did multiple passes to compose the final streetview) watch the ground for the shadows and youll see that they used some kind of push cart with a camera mounted on it. and this is just amazing:

Here's a short thing about what it is, from the University of Arizona
Bull Acad Natl Med. 2009 Apr; 193(4): 849-50 Tavitian B We quantified and compared six parameters (resolution, depth, sensitivity, portability, quantification and cost) of four molecular imaging techniques (MRI, optics, ultrasound and TEP), with the three types of electromagnetic radiation used in vivo (Frequencies (10(6) to 10(22) Hz), Photonic Energy (10(-4) to 10(9) eV) and Wavelengths (10(-2) to 10(-15) m). This form of molecular imaging demands the most sensitive technique available (Pl. 26-2 to 26-4). Four examples of experimental in vivo approaches on small animals are shown: molecular passage through the blood-brain barrier (endothelial cells, astrocytes and occludin, pharmacokinetics, studied with PET) (Pl. 2-5. to 2-11); imaging of receptors and ligands, especially peripheral benzodiazepine receptors (PBR) by PET and MRI in the rat (Pl. 2-12 to Pl. 2-15); neuropathology of neurodegenerative and inflammatory diseases and stroke by PET and MRI in the rat (Pl. 2-16 to 2-17);…

ok, you could have asked this in the astronomy & space forum too – but it's ok in Physics…
The magnification of a telescope is given by
M = -Focal_length_of_scope / Focal_length_of_eyepiece. So we can rearrange this to be
-M*5mm = Focal_length_of_scope = 225*5 mm = 1125mm
To work out the total length of the scope remember that the focal lengths of the eyepiece and scope are added together – so you could expect it to be about 1130mm long.

It does to me. The high power comes from more sharply curved lenses, and to curve them sharply they must be small.
