Since the angle is 90degrees, 2 out 3 sides are the same. The 2 triangles obtained after divided are basically the same triangle, symmetry of each other
Thus, we can conclude that a b, d e
4. Try describing 1 object 2 ways
Explaining something in 2 different perspectives. 2 different paths to the same object, likely to have some different knowledge points. This helps to have more connections. Thus, coming out with more creative ideas
For example, counting the possible permutation of a string of 5 bits. 1) Count the exponential 2) Count the possible permutation one by one
Insights & ingenuity is basically pattern recognition
Using obsidian to connect the ideas, structure messy knowledge nodes, let nodes interconnect with each other, form a network of pattern recognition, so each node has a lot of contact points via directly and indirectly connected nodes
With connections and repetitions, the knowledge points will be embedded into sub-conscious which is much more efficient than and powerful than conscious
8. Always gut-check your answer
There isn’t perfection, the ability to identify mistakes & give fixes is golden
9. Learn at least a little bit of programming
Helps to provide a different perspective to math which is very abstracted
We can also take advantage of its ability to generate a massive set of numbers to get a rough estimation trend or pattern
