How did Conan use his watch to determine his bearings in Detective Conan?

It's as simple as dividing the time you're in by 2, finding the corresponding position of the quotient on the dial, and pointing that number at the sun, where the "12" dot on the dial points to north. For example, at 10 a.m., divide by 2 and the quotient is 5. Align the "5" on the dial with the sun, and the "12" will be north.

Once the north is determined, the other directions are clear at a glance. Keep in mind, however, that if it's in the afternoon, it should be calculated according to the 24-hour chronology. If it is 4 p.m., it will be counted as 16 o'clock.

Finding directions in this way is no less accurate than a compass. The direction finding of the watch "the hour folds half to the sun, 12 refers to the north", generally between 9 a.m. and 4 p.m., you can quickly identify the direction, with half of the time pointing to the sun, 12 hours is the north, such as the time of 14:40 in the afternoon, half of which is 7:

20, the hour is directed to the sun, then 12 refers to the north, or the watch is flat, the hour hand points to the sun, and the reverse extension of the hour hand and the 12-hour bisector is the north; Or put a watch, put a small stick vertically on the watch** and turn the watch, so that the shadow of the small stick coincides with the hour hand, and the bisector between the hour hand and the 12 hours is the north. It must be noted that: (1) when determining the direction, the watch should be flat; (2) It should not be used around noon in areas between 20°30 north and south latitudes, that is, the meridian of standard time shall prevail, add 1 hour for every 15° to the east, and subtract 1 hour from 15° to the west.

Beijing time should be converted to local time. Based on 120° east longitude, for every 15° east longitude, add 1 hour to Beijing time, and subtract 1 hour from Beijing time for every 15° west, which is the local time. If the geographical coordinates of Urumqi are east longitude, then (120, roughly 2 hours.

Subtract 2 hours from Beijing time, which is the local time of Urumqi, and so on. Note: In summer, the above methods are not applicable in Chiayi, Taiwan Province, Nanao Island northeast of Shantou, Guangdong Province, Wuzhou, Guangxi Zhuang Autonomous Region, and Yunnan Province.

How to do it: Lay the watch flat, fold the count of the hour hand on the watch (calculated by 24 hours) in half when observing, and use this folded half to align with the position of the sun at that time. At this time, the reading "12" on the dial of the watch points in the direction of the north.

In this way, other directions can be identified. So as to determine the bearing. In case of rainy days, the position of the sun can be roughly estimated according to the usual observation experience, and then the direction can be determined according to the above method.

For example, if it's 2 p.m. (i.e., 14 p.m.), you align the position of the sun with a "7" half of the "14", and the direction of the dial "12" is north.

Normally, the sun is in the east at 6 a.m., south at 12 noon, and west at 18 p.m. In the field, as long as there is a watch and there is the sun during the day, you can take the watch off and put it on the palm of your hand, and align the scale of the watch with the sun after the time is halved, and dial 12 refers to the north. For example:

It was 14 o'clock and you had to look for directions, and the time was halved to 7 o'clock. This should be pointed to the sun on the dial with the scale 7 on the dial, and 12 on the dial refers to the north. To be more precise, you can use a thin, straight needle or twig to stand on the point where the hour is halved and slowly turn the clock so that the shadow of the needle passes through the center of the dial.

At this time, the center of the dial and the 12-scale extension direction is north.

I read it in a book before.,Upstairs said it right.,But when I read it.,I think Conan did it so fast ==.

Upstairs it was very clear......If you study high school geography in the future, the teacher will talk about it as a supplement.

Detective Conan's watch can fire an anesthetic needle. The Conan watch has many functions, including a button to adjust the time, a lid that can be erected, and an anesthetic needle that instantly anesthetizes a person by pressing the button, but be cautious when using the anesthetic needle, in case you miss, you will be in trouble.

The anesthetic needle function of Conan's watch can be used in almost every episode.,Mainly used to deal with Maori Kogoro.,In addition to this function,The watch also has an intercom function.,You can communicate with other friends.,But Conan only uses it in an emergency.。

In addition, the watch has a flashlight function, which is very important in the time of adventure, and can be of great help to Conan. Of course, there is also the aiming function, which is used at the same time as firing the anesthetic needle, which can accurately launch the anesthetic needle into the correct position, such as the back of Mori Kogoro's neck.

The most basic function of Conan's watch is to see the time, which is a function that every watch has, so Conan will carry the watch with him.

Method 1: The sun rises in the east and sets in the west, so you can find the east-west direction according to it. With just one watch, you can find the north-south direction (depending on which hemisphere you are in).

If the weather is cloudy, it is judged by the brightest place in the sky (the sun). If you don't have a watch, as long as you know the time at that time, draw a watch on paper with the position of the hour hand in line with the time at that time, and use the above method to determine the direction.

Northern Hemisphere: Point the hour hand in the direction of the Sun and imagine a line at one-half of its angle to 12 o'clock, which is the direction it points to the south.

Southern Hemisphere: Point the sun at 12 o'clock, and point north at half the angle between the hour hand and 12 o'clock.

Method 2: Divide the time you are in by 2 and align the resulting quotient with the sun, and the direction indicated by 12 on the dial is north.

Between 9 a.m. and 4 p.m., you can quickly discern the approximate direction by following the following phrase: "The hour is half a pair of the sun, and '12' refers to the north." If it is 9 a.m., it should be directed towards the Sun at 4:30 a.m.; For example, at 2:40 p.m. (i.e. 2:40 p.m.), the sun should be directed at 7:20 p.m., and the direction of the "12" is north.

It is important to note that:

1 "Hours" refers to 24 hours in a day, e.g. 1 p.m. at 1 p.m.

2 When determining direction, the watch should be flat (face up).

3 This method should not be used around noon in areas between 2o°30' north and south latitudes.

4 Be aware of jet lag. That is, "based on the meridian of standard time, add 1 hour for every 15° to the east, and subtract 1 hour for every 15° to the west." of the method to convert standard time to local time.

The time is directed in the direction of the Sun, and the bisector at the angle of 12 is south. Without the sun, you can't use it.

I set my watch to 3 o'clock, and the short hand was aimed at the sun, and then at 3 o'clock and 12 o'clock in the middle was the south, which I saw in a Conan magazine.

I think Conan's watch should have a compass, and if you look at it from angles, there must be symmetry, for example, if you face the sun in the morning, the upper hand is east, and the lower hand is west. If there is no symmetry, it is not true.

It should be half of the angle between 12 and 6、、、 but if it's 6 o'clock in the winter, can you still see the sun、、、

Please note! Since our place is too far from the latitude and longitude of Tokyo, we are not suitable for this method!

He used it many times, and I couldn't see the sun, so it didn't hold true for me.

The cow man made the "watch" of Detective Conan, and there is only one truth.

The watch can fire an anesthetic needle.

In this way, it is convenient for Conan to solve the mystery through the mouth of Maori Kogoro.

Determine the orientation of the viewing time and launch the anesthetic needle.

Is it real or TV, please?

Here's how to use a watch to argue for direction::

The earth rotates 360 degrees in 24 hours and 15 degrees in an hour, and the hour hand of a watch always rotates twice as fast as the sun. At 6 o'clock in the morning, the sun is in the east, and the shadow points to the west, at this time, the hour hand on the watch points to the sun, and the "12" on the dial points to the west, if the dial rotates 90 degrees, it is half folded at 6 o'clock, so that the "3" on the dial is facing the sun, and the "12" is pointing to the north; At 12 noon, the sun is in the south, and the 12 is halved so that the "6" on the dial is facing the sun, and the "12" still refers to the north (fig. 6).

According to this method, the direction is determined, taking into account the local time difference. Beijing time should be converted to local time. Based on the 120th parallel of east longitude, Beijing time is added by one hour for every 15 degrees of longitude to the east, and Beijing time is subtracted by one hour for every 15 degrees to the west.

For example, if the geographical coordinates of Urumqi are 87 degrees 40 minutes east longitude, then (120° 87°) 15° 2 hours and 9 minutes, and Beijing time minus 2 hours and 9 minutes, is the local time of Urumqi.

The above two methods cannot be used in the area south of the Tropic of Cancer (23 degrees 27 minutes north latitude) in Chiayi, Taiwan, Nanao Island, northeast of Shantou, Guangdong, Wuzhou City, Guangxi, and Gejiu City in Yunnan.

By the way, we know that the Earth and the Sun move 15° relative to each other during the rotation of the Earth, and we can roughly determine the direction with a watch and the Sun. Conversely, we can also determine the approximate time with a compass and the sun. To do this, use a compass to orient the sun north, and divide the reading of the sun's bearing by 15.

In China, Beijing time is the standard, Beijing is on the east longitude 120 ° line, and other regions should be corrected according to the longitude difference, that is, the correct solar time.

It's a principle that uses mathematics, and it's too cumbersome to remember.
