UNDER MILK WOOD. “It is spring, moonless night in the small town, starless" "and bible-black, the cobblestreets silent and the hunched," "courters'-and-rabbits' wood limping invisible down to the" "sloeblack, slow, black, crowblack, fishingboatbobbing sea.” https://lnkd.in/d_SJ2Qe View in LinkedIn

FRAGMENT FROM NATURE carries on from last weekend and concludes this weekend on the probability argument for the sample space searched in our exploration of outer space, specifically for signs of life biosignals, and the variety they could assume. Instead of simply taking a flat-footed binary position, this paper presents a thoughtful discussion on the topic. We can all use a refresher in logical thought. View in LinkedIn

SOLAR NEUTRINO SEARCH. “Any experiment such as this, which does not have the requisite sensitivity, really has no bearing on the question of the existence of neutrinos. To illustrate my point, one would not write a scientific paper describing an experiment in which an experimenter stood on a mountain and reached for the moon, and concluded that the moon was more than eight feet from the top of the mountain.” https://lnkd.in/dKzsrBv View in LinkedIn

FALSE PREMISE. “But the reviewer is incorrect. It is not at all hard to imagine that prehistoric humans around the world performed just such an experiment, told others about it, and in so doing significantly advanced their understanding of the cosmos.” https://lnkd.in/dKzsrBv View in LinkedIn

FALSE UPPER LIMIT. “Similarly, in SETI, the first upper limits will necessarily rule out only extremely obvious manifestations of alien technology, and may seem at first to "have no bearing on the question of the existence of" alien life.” https://lnkd.in/dKzsrBv View in LinkedIn

WEAK UPPER LIMIT. “For instance, Griffith et al. (2015) put weak upper limits on the total waste heat across entire galaxies, concluding that out of 100,000 galaxies, none had a galaxy-spanning species harnessing more than 85% of the galaxy's starlight. This result might hardly be surprising given that this upper limit is near the extreme limit of what galaxy-spanning technology could accomplish.” https://lnkd.in/dKzsrBv View in LinkedIn
