As for this note, we'll talk about the basics of memory neuroscientifically.
Remebering from our basic biology lessons, we know that the brain contains *neurons that store information*.
These information can be connected together with *synapses that represents a web of thoughts*.

The memory can be compared to the muscles as it strengthens the more you use and decays the more you neglect.
In order for this to work, however, you need to set some time for the neural structure to harden first.
This is why cramming doesn't work and [[id:063dfd73-dbf5-437b-b6f1-d7aeca196f31][Spaced repetition]] is often considered a better method.

Knowing [[id:25fb4ebf-2cc4-40fe-93ad-37a79aedfb41][The basics of memory]], our neurons represent more like a web of thoughts.
Innovation often comes from combining aspects from a network of ideas.
Our brain is good at relating each topic with something else.
To exemplify the point further, try to start at a single word and make a word map around it.
This is subtly present in daily life mostly filled with links from one thing to another.

Memory palaces are one of the more known technique from memory sports.
Notice how most of them tend to make a lot of effort grouping items together and weaving them with familiar concepts such as their house.
Another interesting thing with this technique is the test of creativity.
Going back to the memory sports scene, they usually employ this technique by creating a narrative leaning on crazier side of things.
This makes it more memorable and easier to write more things on top of the wacky antics.

# TODO: Improve note
- human tendency to chunk or group items together
- this is similar to we form memories
- the neuroscientific process of learning is also similar: starts from learning bits of information and eventually combining them, condensing information into chunks
- applicable on outside of the learning process: speedtyping, memorizing, problem solving, finishing a project, etc.
- [[id:05a39f96-fb1c-4d71-9be1-fc4c2e251e8f][Start small and improve later]]
The behavior of chunking is present in a lot of ways.
- When we hear the word "popsicle", you may have already envisioned an image of the popsicle.
- Memorizing a phone number, dividing the number into groups — e.g., 39281841938 into 392-818-419-38.
- When learning about speedtyping, you may have heard of the advice to learn typing by syllables instead of individual letters.
- In formal education, most higher-level topics are essentially combining previous topics — e.g., learning mathematics in formal education tends to be: learning the numbers, to counting, then arithmetics, and finally branching out to algebra, geometry, statistics, and calculus.
- Problem solving tends to be divided into subtasks.
Neuroscientifically, a chunk is a group of neurons learned to sing in tune whenever we react in a certain way.
Chunking makes it easier to hold more information with fewer mental resources.
We learn bits of information, combining them into chunks, condensing the information.
This condensed information can then be combined with other information thereby creating a web of information (or scientifically, neural structures).

The learning process is not perfect and just like everything else in life, there are some traps that you could step in.
This could cost you either time or forming bad habits that require unlearning later.
The following is an exhaustive list of things to look out for.
- the presence of the material itself can fool the student thinking they already know the material
+ solution: close the material and practice self-testing
- overlearning: tackling the material for complete mastery for the nth time
+ solution: simply move on once you already know the basics of the concept
+ Remember [[roam:Most of the work is done from some effort]]
- being invested in an idea that you cannot see other solutions
+ solution: do some occasional workshopping with related concepts or tools
+ this is the reason why most of the discoveries are made either by young people or those who haven't formally trained or studied for the original field
- working with solutions can be a trap if you focus solely on the steps
+ solution: give time to focus on the bigger picture
+ inversely, understanding without the memorization is still bad, [[id:c0e4fb0e-68f2-4db4-8c3e-f5a7845738c3][Understanding comes first from memory]]
