Physics Explorer on Instagram: "Chameleons change their color through special cells in their skin called chromatophores and iridophores. Chromatophores contain different pigments like red, yellow, and brown, while iridophores have tiny crystals that reflect light. By expanding or contracting these cells, chameleons can mix pigments and control how light is reflected, which creates a wide range of colors. This ability is not just for camouflage; chameleons also use color changes to communicate em

Anatomy of Motion on Instagram: "Our body has a great triple stage landing amortization mechanism. At the lowest level, foot and ankle absorb energy by going into pronation in order to smooth the peak of force which will be transferred higher. At the second stage, the knee is drawn into flexion which allows quads to work as energy buffers. This knee movement also entails ankle dorsiflexion, which activates calf muscles as secondary buffers. All those actions help to spread the impact force as a
