  2. Spontaneous process - Wikipedia

    en.wikipedia.org/wiki/Spontaneous_process

    In thermodynamics, a spontaneous process is a process which occurs without any external input to the system. A more technical definition is the time-evolution of a system in which it releases free energy and it moves to a lower, more thermodynamically stable energy state (closer to thermodynamic equilibrium ).

    Spontaneous generation, the first naturalistic theory of abiogenesis, goes back to Aristotle and ancient Greek philosophy, and continued to have support in Western scholarship until the 19th century. [15] The theory held that "lower" animals are generated by decaying organic substances.

  4. Spontaneous recovery - Wikipedia

    en.wikipedia.org/wiki/Spontaneous_recovery

    For spontaneous recovery to occur, the conditioning of the memory that is recalled later needs to be stored in long-term memory. It is a process where the semantics and associations of the certain memory are so ingrained that they can become habitual or automatic to the person. For example, all the procedures needed to ride a bicycle are not ...

  5. Protein folding - Wikipedia

    en.wikipedia.org/wiki/Protein_folding

    Protein folding must be thermodynamically favorable within a cell in order for it to be a spontaneous reaction. Since it is known that protein folding is a spontaneous reaction, then it must assume a negative Gibbs free energy value. Gibbs free energy in protein folding is directly related to enthalpy and entropy. [12]

  6. Abiogenesis - Wikipedia

    en.wikipedia.org/wiki/Abiogenesis

    The spontaneous formation of complex polymers from abiotically generated monomers under the conditions posited by the "soup" theory is not straightforward. Besides the necessary basic organic monomers, compounds that would have prohibited the formation of polymers were also formed in high concentration during the Miller–Urey experiment and ...

    The process of osmosis over a semipermeable membrane.The blue dots represent particles driving the osmotic gradient. Osmosis (/ ɒ z ˈ m oʊ s ɪ s /, US also / ɒ s-/) [1] is the spontaneous net movement or diffusion of solvent molecules through a selectively-permeable membrane from a region of high water potential (region of lower solute concentration) to a region of low water potential ...

    The first flight carrying "high-threat" migrants to Guantanamo Bay arrived Tuesday evening, part of the Trump administration's crackdown on illegal immigration. The C-17 plane took off from El ...

  9. Particle decay - Wikipedia

    en.wikipedia.org/wiki/Particle_decay

    In particle physics, particle decay is the spontaneous process of one unstable subatomic particle transforming into multiple other particles. The particles created in this process (the final state) must each be less massive than the original, although the total mass of the system must be conserved.
