Time Preference Rate. “The Marshmallow Tale” by Joachim de Posada and Ellen Singer describes the “Marshmallow Experiment” at Stanford University. The experimenter left the child alone in the room and gave the child a marshmallow, instructing the child to eat it immediately. However, if the child did not eat it within 15 minutes, the experimenter would give the child another marshmallow. Some children waited the full 15 minutes, while others stopped waiting early. These two groups were followed for 14 years, and as a result, the more patient children showed better social and mental abilities. Those who cannot tolerate waiting are said to have a high time preference rate, while those who are patient are described as having a low time preference rate. In investment, high and low time preference ratios are not necessarily good or bad because many investments depend on luck. The key is to find and stick to methods and principles that match one’s own tendencies. - Joseph’s “just my thoughts”
The reason pencils can be writing instruments is due to pencil lead. The material used for pencil lead is graphite. The graphite element is carbon (C), and four carbon atoms are combined. One carbon atom can have four bonds and can combine with another element. Diamond is similar to graphite, with four carbon atoms. However, diamonds have four carbon bonds that create a strong covalent bond with other carbon atoms, while graphite has only one weak bond. We can write or draw with a pencil because of this loose combination. When you apply pressure to the pencil with your finger, this weak bond in graphite breaks, leaving some of the crystals damaged. Don’t view it merely as a pencil; it’s a diamond’s cousin. The degree of consanguinity is very, very close. - Joseph’s “just my thoughts”
