Why doesn't it go dark when we blink?

We are able to see an object when light from those objects enter our eyes and hit the retina of our eye.But when we blink, our retina doesn't receive any light.

THEN WHY DOESN'T IT APPEAR DARK?😕😕😕

Because our brain suppresses this information from retina,ignoring the darkness.Thus,we don't consciously realize that it has gone dark.

Also,expert say,a part of our brain called Medial Prefrontal Cortex, stores the last image we see before blinking and uses it to fill in the darkness.Thus, we feel that we are watching a continuous picture,without interpretation.

In addition to this,if we blink while watching a moving object,our brain gauges the difference in positions of the moving object,before and after the blink.Accordingly,it adjust our eye muscle,helping them to maintain focus on the moving object,even after the blink.

How Energy conversion from coal is done?

Single generator sets of over 600 MW are now used in the UK, though there are many smaller generators in use. A 600 MW generator can supplythe average needs of over 1 million UK households. Three or four such generators are typically installed in a single large coal-fired station which isoften sited close to a coal mine, away from the city dwellers who consume the electricity. Such generators are usually driven by a compound arrangement of highpressure, intermediate-pressure and low-pressure turbines, increasing in size as the pressure decreases. Modern turbines rotate in a speed range from 1500 to 3500 r.p.m., usually 3000 r.p.m. for the UK’s 50 Hz system. For large coal-fired plant the steam pressure could be 25 megapascals (MPa) with steam temperatures of 500–600 °C to improve the thermodynamic efficiency. In nuclear reactors, which operate under less demanding conditions, the steam is superheated to about 5 MPa and 300 °C. Modern water tube boilers are complex and have ...

5 TOP FACTS LIGHTHOUSES

1 The builder of the Lighthouse of Alexandria, Sostratus – disobeying orders from the pharaoh Ptolemy – engraved his name and a dedication to the sea gods on the tower base. Fame 2 The technical term for the study of lighthouses is ‘pharology’, a word derived from Pharos, the island upon which the great Lighthouse of Alexandria once stood. Academia 3 George Meade built many notable lighthouses in the US during the classical lighthouse period. He is remembered in history as the winning general in the Battle of Gettysburg. War 4 The tallest lighthouse in the world is the Yokohama Marine Tower in Yokohama, Japan. The structure ﬂ ashes alternately green and red every 20 seconds. Tallest 5 Originally lighthouses were lit merely with open ﬁ res, only later progressing through candles, lanterns and electric lights. Lanterns tended to use whale oil as fuel.
