2. Second law of thermodynamics - Wikipedia

   en.wikipedia.org/wiki/Second_law_of_thermodynamics

   The second law of thermodynamics is a physical law based on universal empirical observation concerning heat and energy interconversions. A simple statement of the law is that heat always flows spontaneously from hotter to colder regions of matter (or 'downhill' in terms of the temperature gradient).

3. Science - Wikipedia

   en.wikipedia.org/wiki/Science

   Science is a systematic discipline that builds and organises knowledge in the form of testable hypotheses and predictions about the universe. [1] [2] Modern science is typically divided into two or three major branches: [3] the natural sciences (e.g., physics, chemistry, and biology), which study the physical world; and the behavioural sciences (e.g., economics, psychology, and sociology ...

   The second shell similarly contains a 2s orbital, and it also contains three dumbbell-shaped 2p orbitals, and can thus fill up to eight electrons (2×1 + 2×3 = 8). The third shell contains one 3s orbital, three 3p orbitals, and five 3d orbitals, and thus has a capacity of 2×1 + 2×3 + 2×5 = 18.

8. Second messenger system - Wikipedia

   en.wikipedia.org/wiki/Second_messenger_system

   The activated α subunit activates phospholipase C, which hydrolyzes membrane bound phosphatidylinositol 4,5-bisphosphate (PIP 2), resulting in the formation of secondary messengers diacylglycerol (DAG) and inositol-1,4,5-triphosphate (IP 3). [10] IP 3 binds to calcium pumps on ER, transporting Ca 2+, another second messenger, into the cytoplasm.
