Such is history; such is the history of civilization for thousands of years. To interpret history from this viewpoint is historical materialism; standing in opposition to this viewpoint is historical idealism.

The Lounge Nov 27, Dregster However, the relative position Kamaru Usman the two images will remain steady, and as long as the user can determine when the celestial object touches the horizon, the accuracy of the measurement will remain high compared to Pluspunkt Freiburg magnitude of the movement. Latest Threads. The estimation of this angle, the altitude, is known as sighting or shooting the object, Political Sextant taking a sight. This time's Brick Teig Also, I expected nothing less than your Superenalotto agree being less than fifty percent somehow. For the astronomer's sextant, see Sextant astronomical. Since 1 minute of error is about a nautical milethe best 777.Com accuracy of celestial navigation is about 0.
Since 1 minute of error is about a nautical mile , the best possible accuracy of celestial navigation is about 0. At sea, results within several nautical miles, well within visual range, are acceptable.
A highly skilled and experienced navigator can determine position to an accuracy of about 0. A change in temperature can warp the arc, creating inaccuracies.
Many navigators purchase weatherproof cases so that their sextant can be placed outside the cabin to come to equilibrium with outside temperatures.
The standard frame designs see illustration are supposed to equalise differential angular error from temperature changes.
The handle is separated from the arc and frame so that body heat does not warp the frame. Sextants for tropical use are often painted white to reflect sunlight and remain relatively cool.
High-precision sextants have an invar a special low-expansion steel frame and arc. Some scientific sextants have been constructed of quartz or ceramics with even lower expansions.
Many commercial sextants use low-expansion brass or aluminium. Brass is lower-expansion than aluminium, but aluminium sextants are lighter and less tiring to use.
Some say they are more accurate because one's hand trembles less. Solid brass frame sextants are less susceptible to wobbling in high winds or when the vessel is working in heavy seas, but as noted are substantially heavier.
Sextants with aluminum frames and brass arcs have also been manufactured. Essentially, a sextant is intensely personal to each navigator, and they will choose whichever model has the features which suit them best.
Aircraft sextants are now out of production, but had special features. Most had artificial horizons to permit taking a sight through a flush overhead window.
Some also had mechanical averagers to make hundreds of measurements per sight for compensation of random accelerations in the artificial horizon's fluid.
Older aircraft sextants had two visual paths, one standard and the other designed for use in open-cockpit aircraft that let one view from directly over the sextant in one's lap.
More modern aircraft sextants were periscopic with only a small projection above the fuselage. With these, the navigator pre-computed their sight and then noted the difference in observed versus predicted height of the body to determine their position.
A sight or measure of the angle between the sun , a star , or a planet , and the horizon is done with the 'star telescope ' fitted to the sextant using a visible horizon.
On a vessel at sea even on misty days a sight may be done from a low height above the water to give a more definite, better horizon.
Navigators hold the sextant by its handle in the right hand, avoiding touching the arc with the fingers.
For a sun sight, a filter is used to overcome the glare such as "shades" covering both index mirror and the horizon mirror designed to prevent eye damage.
By setting the index bar to zero, the sun can be viewed through the telescope. Releasing the index bar either by releasing a clamping screw, or on modern instruments, using the quick-release button , the image of the sun can be brought down to about the level of the horizon.
It is necessary to flip back the horizon mirror shade to be able to see the horizon, and then the fine adjustment screw on the end of the index bar is turned until the bottom curve the lower limb of the sun just touches the horizon.
The angle of the sight is then read from the scale on the arc, making use of the micrometer or vernier scale provided.
The exact time of the sight must also be noted simultaneously, and the height of the eye above sea-level recorded.
An alternative method is to estimate the current altitude angle of the sun from navigation tables, then set the index bar to that angle on the arc, apply suitable shades only to the index mirror, and point the instrument directly at the horizon, sweeping it from side to side until a flash of the sun's rays are seen in the telescope.
Fine adjustments are then made as above. Joined Mar 18, Posts 3, Reaction score 0 Online 5m. You must log in or register to reply here.

But anyways here's my results. I am not as Marxist, and especially not as anarchist, as these results seem to belie.
I am certainly far more socialist in overall beliefs than capitalist, sure, but not like this. Oct 25, 11, Oct 25, 12, Highest - Social Democracy Lowest - Strasserism.

Got the exact same results. This lines up with my views pretty well. Last edited: Jul 10, Princess Viola Member. Oct 29, 1, Florida.
Exellus Member. Oct 30, 1, Exellus said:. The device consists of an arc of a circle, marked off in degrees, and a movable radial arm pivoted at the centre of the circle.
A telescope, mounted rigidly to the framework, is lined up with the horizon. The radial arm, on which a mirror is mounted, is moved until the star is reflected into a half-silvered mirror in line with the telescope and appears, through the telescope, to coincide with the horizon.
The angular distance of the star above the horizon is then read from the graduated arc of the sextant. From this angle and the exact time of day as registered by a chronometer, the latitude can be determined within a few hundred metres by means of published tables.
Sextants were first developed with wider arcs for calculating longitude from lunar observations, and they replaced octants by the second half of the 18th century.
