The mystery of observation-woodmam

How can one not be wet if there is hair on one's head, according to the norm? So, one must break the rule: imagine that the young man's father had no hair on his head and was bald, and that would be the answer. In fact, this man is really bald. This is how to think out of the box.

  There is a bridge across the river in an east-west direction, and it takes five minutes for a person to cross it. There is a pavilion in the middle of the bridge. There was a watchman in the pavilion who came out every three minutes and when he saw someone crossing, he told him to go back and not to cross. A clever man thought of an ingenious way to get across the bridge. What did this clever man think of to cross the bridge?

  The clever man thought of a way: he crossed the bridge from east to west and after two and a half minutes turned his face to go east. When the watchman came out and saw him, he ordered him to walk backwards so that he could turn around and cross the bridge. If the routine had not been broken, this man would not have been able to cross the bridge in any case.

  I. What is the power of observation

  The world contains infinite mysteries, and is a vast and profound place. Understanding the world is an eternal subject for mankind. Observation and the power of observation have become a rainbow linking human beings to the world. It is through observation and reflection that mankind is able to gradually understand the wonders of the world and transcend itself.

  1. The mystery of observation

  Observation - "the perception of thinking"

  Literally, both "observe" and "observe" are naturally linked to the eye, and both can be interpreted as "seeing". The word "inspect" means "to look closely". But is "look" the same as "observe", or is "not looking" necessarily the same as not "observing"?

  The answer is no.

  In the process of human understanding, the eyes are indeed the most important sensory organ. In the Nei Jing of the Yellow Emperor, it is written that "while the sky has the sun and the moon, man has two eyes" and that the eyes can "see all things, distinguish between black and white, and judge the length". Modern physiological research has also proved that there are more than 4 million nerve fibres in the human body that transmit information to the brain centre, of which the eyes account for half; 80% to 90% of the hundreds of millions of trillions of information that people obtain from the outside world is obtained through the visual channel.

  But the eyes are not the only sense organ. In addition to seeing the colourful external world with their eyes, people can also use their ears to listen to beautiful and moving music, high and low sounds, and also use their nose to smell refreshing smells, or use their tongue to taste sour, sweet, bitter, spicy and salty tastes, or use their hands to touch and feel the different textures, hardness, hot and cold of objects ...... This series of sensory organs, too, should not be ignored.

  However, there are often people who are "blind" to what is in front of them, and others who are "deaf" to the sounds in their ears. This shows that the sensory organs alone are not enough to complete the activity of observation. The information received by the sensory organs is not reflected in the brain due to the lack of involvement of the thinking process. This suggests that active thinking must be involved in activities such as seeing and hearing in order to obtain a true observation. For this reason, psychologists call observation "the perception of thought".

  Since observation is 'thinking perception', the highest form of perceptual development, it is not random or ambiguous. It is based on a combination of visual, auditory, tactile and olfactory, orientation and distance perception, pictorial discrimination, and the ability to recognise time.

  Therefore, we believe that the process by which people rely on their sensory organs (mainly the eyes) to obtain purposeful, planned and active perception is called observation.

  Classification of modes of observation

  We usually classify the ways of observation into two main categories: direct observation and indirect observation.

  (1) Direct observation

  Direct observation generally refers to the process of perceiving an object directly through one's sensory organs.

  Direct observation is often closely related to spontaneous observation, has no intermediate links, is more credible and is conducive to problem identification. However, people have very limited sensitivity and range to perceive things with the naked eye or other sense organs. The human eye can barely distinguish things that are 15 cm away and 0.1 mm away; it is very difficult to distinguish smaller things, much less see prey on land from several kilometres above like an eagle; and the sensitivity of the human ear is unlikely to rival that of bats and dolphins.

  (2) Indirect observation

  Indirect observation refers to the process of perception in which people obtain information about an object indirectly with the help of observation instruments.

  Indirect observation is often linked to conscious observation, and can employ scientific methods such as surveys and experiments, as well as tools such as the Hubble telescope, tunnel-scanning microscopes, ultrasound, nuclear magnetic resonance, etc. The use of different methods and equipment to extend the human sense organs is a very important means of observation and is more conducive to problem solving. However, it is likely to result in incorrect observations, or even no observations at all.

  There are advantages and disadvantages to both direct and indirect observation, one cannot be without the other. Only by choosing different methods according to different situations can we ensure that the observations are correct and scientific.

  In addition, people have classified observation methods from a variety of different perspectives. For example, they are divided into scientific observation, social observation and aesthetic observation according to subject areas; they are divided into revelatory observation, exploratory observation and verification observation according to the purpose of observation; they are divided into continuous observation and discontinuous observation according to time cycles.

  2. What is the power of observation?

  The power of observation: a special form of perceptual ability

  Simply put, a person's ability to observe is the power of observation.

  The power of observation is the ability to accurately, comprehensively and deeply perceive the characteristics of objective things through the sensory organs of the eyes, ears, nose, tongue and body in the process of perceptual activity. As a special form of perceptual ability, observation is an important part of human cognitive ability. The degree and level of human understanding of things is highly related to the strength of this ability.

  People often praise those who have developed their powers of observation as having a "clear mind and bright eyes", where "bright eyes" does not mean how good a person's eyesight is, but rather that they are meticulous and accurate in their observations and quick in their thinking and judgement. In this sense, observation is the ability to coordinate the senses with the mind, and is also a form of intelligence.
