This piece explores three key concepts in nature and science: photosynthesis, the importance of symmetry in shapes, and the principles of stopping distances. It discusses how leaves absorb sunlight and carbon dioxide to produce energy, the significance of symmetrical patterns in various forms, and the calculations involved in determining safe stopping distances for vehicles. Each topic highlights critical interactions within the environment and the mathematics underlying physical processes, promoting a deeper understanding of our world.
E N D
4. The leaves take energy from the sun, and take carbon dioxide from the air.
6. Some shapes have lines of symmetry
11. Stopping Distances
