Where these words come from

Lovelock, J.E. (1965) 'A physical basis for life detection experiments', Nature 207(4997), 568-570.

Read in Unit 0 · Block 2. Every word below is one you meet in that paper. 18 of the 30 sit in the paragraphs that carry the argument, the ones the reading companion walks through step by step; the rest appear elsewhere in the paper.

The translations below were generated by an AI and have NOT been checked by a human. If you speak one of these languages, you know more than the machine does. Found one that is wrong, awkward, or means something different in science than in ordinary use? Tell your teacher: corrections get your name on them, and a wrong translation you catch counts as a documented AI error.

  1. unequivocal adjective

    Unit 0 · Block 2carries the argument

    Having only one possible meaning. An unequivocal result cannot be argued about.

    Lovelock wants a test whose answer nobody can dispute.

  3. geocentric adjective

    Unit 0 · Block 2carries the argument

    Taking Earth as the centre or the standard. A geocentric question assumes other places work like Earth.

    Lovelock uses this as a criticism. Watch how he turns it into a limitation of other people's experiments.

  4. phenomenological adjective

    Unit 0 · Block 2carries the argument

    Describing what you can observe, without claiming to explain the deeper reason why.

    Lovelock calls his own method this. He is being honest about a limit, not apologising.

    Translator warning: this is the PHYSICS sense (describing observations), not the philosophy sense. Machine translators usually pick the philosophy word. Check carefully.

  7. entropy noun

    Unit 0 · Block 2carries the argument

    How spread-out and mixed-up things are. Left alone, everything becomes more mixed up. Life pushes the other way.

    The most important word in the paper. Lovelock's definition of life turns on it.

    Unit 0 · Block 2carries the argument
