Memory
To experience
Living in the limited time between your birth and your death you will experience quite a lot.
Most of your experiences you discover(ed) by sensory perceptions and emotions.
Sensory perceptions
You see movements, shapes, contrasts and colors.
You hear sounds in different pitches, tones and strengths.
You smell a fart, the sewer, flowers, perfume or food.
You taste sweet, salty, bitter, sour or umami - the fifth taste - for example seaweed soup.
You feel the (changes of) pressure or temperature on your skin.
If it gets too bad you feel it as pain.
You feel hungry or that you ate enough.
Feelings
The experience of love, safety, beauty and desire are examples of emotions.
To think
One of the tasks of your brains is thinking. The largest part of your thinking is dominated by your
memory. It is hard to imagine how you can think without memory, because what would you be thinking?
Thinking many people use their native language or (fragments of) sentences. Others think in images
as if they were viewing a television. There are also thinkers in sounds and especially in some
animal species the thoughts are experienced as odors.
The memory
The memory is a part of the brains. In them recollections are stored even unconsciously you saw,
heard, smelled, felt or tasted. Basically you remember almost all the ideas that you've ever observed
and their feelings.
Ready knowledge
If your interlocutor asks you for a fact and you can answer than you had at that moment ready knowledge.
Often ready knowledge is not enough present. Sometimes it helps to think hard. You should refresh your
memory. This is a special technique.
External memory
Being sure in advance you cannot know the requested fact, you can search in an external memory.
Consider for example a dictionary, an encyclopedia, a directory, a suitable textbook, a database or
any internet search engine.
Photografic memory
Some things you remember saying. You do not have any trouble to do. There are people who remember
everything they see. They have a photographic memory. They remember all the words example of a page
of a book including the formatting. They know the text literally.
It does not says anything about the understanding of the text. That is another story.
Absolute pitch
Someone with 'absolute pitch' can specify the name of a tone (without any help):
an A, B-sharp, G-flat, high C, ..., do, re, mi, ..., any tone.
To learn
Learning in school, during work, at home, in hobby time or during holidays,
it does not the matter, then you use your memory.
