Speed
For a more productive life, daydream
Time 2
Many remarkable achievements started from idle time.
Neuroscience is finding that when we are idle, our brains are more active. It’s called the brain’s default mode network.
Time 3
How it works.
It’s not saying to be completely idle, but to have an oscillation between deep study with focused attention and daydreaming.
Why every face you draw looks a little Neandertal
Time 4
People tend to draw eyes above the center of the head, but eyes are actually on the center.
This is a really common mistake.
In an experiment, people only did a little better by copying.
Even professionals failed.
Time 5
Three hypothesis why it happens:
1. hair-as-hat hypothesis
2. head-as-box hypothesis
3. face-from-below hypothesis
The results seem to favor the second hypothesis.
Head too short compared with the models on which they were based.
To figure out if it happens to people while perceiving round objects
Birds have clever solution for a cuckoo conundrum
Time 6
Well cuckoos tend to leave eggs in other birds’ nest.
Wrens have a good solution that they sing to their own eggs, so when kids are hatched, they will learn the incubation song but cuckoos babies are gonna fail to do so.
Mom wrens sing more incubation songs to their eggs when hearing cuckoo sounds.
Obstacle
