Today was overcast, the sky bleak. I reviewed science from my textbook, focusing on density—a property of matter calculated by dividing mass by volume. Then, a classic question tricked me: Is 1kg of iron heavier than 1kg of cotton? At first, I missed the fact that they were the same weight, differing only in density. Later, I worked a bit on the periodic table. Memorizing it feels like the greatest obstacle ahead; though I’m not required to do that yet, I know I’ll have to eventually. The atomic numbers and names overwhelmed me, deepening my drowsiness. By the end, it truly felt like a day consumed by science.
