       Thinking (to think over; to ponder on; to reflect on; to deliberate) sī kǎo means for a one or more objects for analysis, comprehensive, reasoning, the activities of the judgement thinking.

Think about how quickly?
It depends what you say “ thinking what ” refers to.

You probably refers to the imagination.I imagine myself is at the Earth, after one second, i imagined myself to the Mars or Centaur's alpha star, or in a distant quasars nearby.If that is the thinking within the meaning of “ ”, then you will argue that thinking have any kind of speed, until an infinite speed.

However, you didn't really walk past the distance, right? i can imagine myself in the Earth's formation, here, but that doesn't mean, i experienced this in the course of this time.I can imagine my own Department in the center of the Sun, but that doesn't mean, i really can exist in such a condition.

In order to bring this issue has the meaning of the sciences, you must be in such a way to define thinking ” “, that is, it may have, in fact available physical methods to measure the speed.

For example, you can think about the only reason entirely because there is a fly from nerve cells to neurons and gushing nerve impulse, any actions that depend on the nervous system depends on these nerve impulses.If you touch a hot stuff, you will handle flinch.However, only when the heat from your hand to your central nervous system, and then another nerve impulses from your central nervous system to your muscles, you can do so.

This kind of unconscious thinking ” “ “ (something i think is hot, i'd better get my hands, otherwise it would harm not ”), may be less than nerve impulse hands and round trip between the central nervous system to fast.Therefore, we must understand, thinking about speed ” “ is the speed of “ ” nerve impulse, otherwise not possible to answer this question.

1846, Germany, a physiologist Mahler hold cognizance pessimistic mood, he cannot detect the speed of nerve impulses.Six years later, in 1852, his former students Helmholtz devoted to measuring the speed of nerve impulses.He is still connected to conduct a study of neural muscles.He is in a different point of measurement of stimulating nerve and muscle contraction caused by the required time.When he stimulate outlying muscle more distant nerves, muscle contraction retardation.According to the delay time.He traces of a nerve impulse experience this segment of the extra distance to the desired time.

The speed of nerve impulses depends on the nerves in thickness.Neural thicker, nerve impulse passes, the faster.The speed of nerve impulses also depends on whether a nerve fat substances sheath isolation.A root affected by the isolation of the nerve conduction velocity ratio nerve impulse is not an isolated neural fast.

Mammalian nerve is the finest in animals.But the best nerve impulse of mammalian neural carriage with the speed of about 100 meters per second, or say, 360 kilometers per hour.

This speed it seems less disappointing.Thinking about speed is not greater than the speed of the old propeller aircraft.But you can imagine, nerve impulse to the human body at any point passed to any other aspect and return to, you only need to use less than 1/25 seconds (not included in the central nervous system for the delay in processing).The longest mammal nerve is in the 30-metre-long blue whale, even here, nerve impulse just half a second more done in the round trip journey Shales, this is a fast.
