Spores Get a Lift

Mushrooms have the challenging task of dispersing spores, typically from heights no more than a few centimeters above the ground. At that altitude, viscosity and friction with the ground mean that air barely moves, if it does at all. And mushrooms rely on a wide range of methods, from explosive launches to rain assistance to making their own weather. Every one of these methods gives spores a lift in altitude to reach higher winds and greater dispersal. (Image credit: A. Bejczi/CUPOTY; via Colossal)

By inserting an artificial word with precisely defined frequency and #dispersion, they test how well different measures detect what’s truly #distinctive.

Their findings uncover that a #TF-IDF -based measure is more sensitive to dispersion variations than other dispersion-based measures. #Evaluation

“Dispersion”

In “Dispersion,” particles spread under the influence of an unseen fluid. Like Roman de Giuli’s work, filmmaker Susi Sie creates macro images that look like ice floes, deserts, and river deltas viewed from above. This similarity of patterns at both large and small scales is a specialty of fluid physics. Just as artists use it to mimic larger flows, scientists use it to study planet-scale problems in the lab.

"La lutte sociale, ça nécessite de l’orga. Et, plus que jamais, on a besoin d’outils fiables pour s’organiser. Au choix, entre m’organiser au McCafé ou dans un bar géré par des meufs trans, c’est vite choisi. Insta est aliénant. Swiper n’est pas un geste militant. C’est déprimant et ça nous nique notre capacité de concentration. Ça nous habitue à des intéractions superficielles et constamment avoir le regard potentiel de 500 personnes est hyper anxiogène. La discrétion c’est important pour s’organiser."

In the Way of Inquiry • Objections to Reflexive Inquiry 2
• https://inquiryintoinquiry.com/2023/02/05/in-the-way-of-inquiry-objections-to-reflexive-inquiry-a/

Our agent of inquiry is brought to the threshold of two questions:

• What actions are available to achieve the aims of the present activity?

• What assumptions already accepted are advisable to amend or abandon?

The inquirer is faced in the object of inquiry with an obstinately oppositional state of affairs, a character marked by the Greek word “pragma” for “object”, whose manifold of senses and derivatives includes among its connotations the ideas of purposeful objectives and problematic objections, and not too incidentally both inquiries and expositions.

In the Way of Inquiry • Objections to Reflexive Inquiry 1
• https://inquiryintoinquiry.com/2023/02/05/in-the-way-of-inquiry-objections-to-reflexive-inquiry-a/

Inquiry begins when an automatic routine or normal course of activity is interrupted and agents are thrown into doubt concerning what is best to do next and what is really true of their situation. If this interruptive aspect of inquiry applies at the level of self‑application then occasions for inquiry into inquiry arise when an ongoing inquiry into any subject becomes obstructed and agents are obliged to initiate a new order of inquiry in order to overcome the obstacle.

At such moments agents need the ability to pause and reflect — to accept the interruption of the inquiry in progress, to acknowledge the higher order of uncertainty obstructing the current investigation, and finally to examine accepted conventions and prior convictions regarding the conduct of inquiry in general. The next order of inquiry requires agents to articulate the assumptions embodied in previous inquiries, to consider their practical effects in light of their objective intents, and to reconstruct forms of conduct which formerly proceeded through their paces untroubled by any articulate concern.
