Real change happens so quickly that we often don’t notice when it occurs. The changing of seasons is a good example. Clearly, winter and spring are very different. It’s hot during the day and cold at night, but when we see spring flowers blooming along the roadside, we realize spring has arrived. We tend to think that big changes will feel different, but sometimes small signs reveal the change. For instance, when our foreheads sweat even with little movement, we recognize that the temperature is getting warmer. What changes might you not notice or recognize? Perhaps your weight? - 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”
