How did Conan use his watch quartz watch and the sun to determine direction?

Look at the direction with the watch: If you want to know the direction, you don't have a compass in your hand. In this case, as long as there is a sun, you can use the watch to find the direction.

Hold the matchstick upright on the ground, then place the watch horizontally on the ground, overlapping the shadow of the matchstick and the short hand, so that the direction of the twelve o'clock on the surface and the middle of the scale pointed by the short hand are south, and the opposite side is north.

If you don't have a match, you can also use small twigs to make the shadow as accurate as possible. If you're engaged in challenging survival activities, remember to wear a watch, as a regular watch is more valuable than a digital watch. Because the hour and minute hands on ordinary watches will become an important tool for survival when necessary.

First use the minute to aim at the sun, and when you look at the direction of the hour hand, it is south, which is not very accurate in reality, such as when the sun is at the head.

There are two ways to do this. First, the hour is directed towards the sun. The acute-angled bisector of the minute and hour hands is a guide. Second, the equinox is aimed at the sun, and the hour hand is the guide.

The time is aimed at the sun, and the 12 o'clock scale points to the south.

In the case where the sun can be seen, when using the local place, the judgment is as follows:

If a 12-hour watch is considered to be half of the 24-hour clock (equivalent to half of the 12-hour clock, if the hour hand is 8 o'clock, then half of the hour hand is 4 o'clock) pointing to the sun, then the original watch points to due north at 12 o'clock.

This is determined according to the principle of the Northern Hemisphere and the rotation of the Earth.

It is often used in the military, when we participated in military training, we were taught and disciplined, and later participated in the college orienteering competition, my compass was broken, I drew the direction of the hour hand on the paper according to the time on the mobile phone, and then faced the sun, and was stunned to find the direction back.

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.

At noon, facing the sun, hold your left hand flat in a line, south in front, north in back, left pointing in the direction of west, and right pointing to east.

In the morning, the right hand points to the east, the direction facing the south is the south, the left hand direction points to the west, and the back is the north.

I remember watching Conan before, but I don't remember it.

If you don't have a compass, how can you tell the direction by the sun and your watch?

You know, if you're in the Northern Hemisphere, the watch knows the time, so it's easy to tell when it's sun! Look at your own shadow, the sun's trajectory is southerly in winter and northerly in summer.

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.

Convert time to 24-hour clock.

Divide by 2 (e.g. 18:30 becomes 9:15).

Find the corresponding position of the hour hand (9:15 is a little more than 9 o'clock) and point it with the sun.

At this time, the direction of 12 o'clock on the surface is north.

The hour is aimed at the sun, and the angular bisector of the minute and hour hand angles points in the opposite direction to the north.

1。Flush the surface of the hand parallel to the orbital plane of the sun.

2. Aim the time at the sun.

3。Equinox the hour hand at the angle of 12 o'clock of the watch. The direction in which the bisector line points upwards is south.

Principle: 0 o'clock local time is due north, the sun rotates one week, the watch hour hand turns 2 times, and the watch time is divided by 2, which is the direction of the sun.

Operation: The watch is laid flat, pointing to the sun at half of local time, and north at 12 o'clock.

Example: Take 14 o'clock in the afternoon as an example, 14 2 = 7, and the 7 o'clock position is aligned with the sun, and the 12 o'clock position points to the north.

It was Conan's first time against Kidd the Thief. At that time, Kidd sent a challenge, and after reading it, Conan used the time of his watch to face the direction of the sun, and at this time, the angle formed by the straight line where the hour hand is located and the straight line in the direction of 12 o'clock, the angle bisector of this corner points to the direction of the south, and the direction is determined.

Aim your minute and hour hand at the midline, which is south.

Look for it at the anime merchandise store.

I wonder if you'll find an identical one.

Hey.

It should be the first few episodes of Dr. Asasa who explained it when he gave him the watch.

Aligning half of the time in Beijing at that time to the sun, 12 refers to the east. 6 is west, 3 is south, and 9 is north. In the Southern Hemisphere the opposite.

In the Northern Hemisphere, the hour is aligned in the direction of the Sun, and the midline of the angle between the 12-o'clock scale and the hour hand is due south, and in the Southern Hemisphere, remember the mantra: the hour is half a pair of the Sun, and 12 is the north.

Also remember to be local time.
