1. Why the stars will flash flash it?
Because we can see stars sparkle, this is not because of the stars change their brightness, but with the atmosphere, blocking the.
Across the atmosphere between us and the stars, when the starlight through the atmosphere, they will receive the impact of atmospheric density and thickness. The atmosphere is not absolutely transparent, its transparency will be different according to the density difference. Therefore, we look at the stars on the ground through it, you'll see the stars as if flashing the same again.
2. Plug tips
Why are electric fans, washing machines, refrigerators and other household appliances are mostly three-wire plug to use? Three-phase three-wire plug and plug What is the difference? Three-phase electrical means three different firing line, they are each of the voltage between the two lines is 380 volts, are generally used for power system, prevalent in the industrial use of electricity. The household appliances generally use the single-phase power supply, the three lines are FireWire, zero line (neutral line) and ground, FireWire, and the zero-line voltage between 220 volts, so this is not a three-phase electricity, it plugs and sockets are not three-phase three-phase plug and socket is the ground for safety.
3. On one occasion, Newton concentrate in the laboratory experiments, even a meal time forgot. He then took an assistant several eggs, and sent to a laboratory to go to the Newton said: "There are a few eggs, you cook to eat." Newton said: "Well, thank you, would you please put all their eggs where the bar. "finished, he buried experiment. After a very long time, Newton's hungry, and he come not to eat lunch. So he readily took a pot, put eggs in pot to the stove for a while, they began to start experiments. After a half an hour, Newton finished the experiment. Then he remembered the pot of eggs. He opened the lid a look inside there are no eggs, only a pocket watch. Newton was shocked, looked up, eggs are still on the table, but the table pocket watch had disappeared. Newton too much to concentrate on the original experiment, the results of the pocket watch as eggs to cook.
