Anton Petrov - Mindblowing Video of Plants Talking to Each Other In Real Time and Other Complex Life Forms

1:30 Volatile compounds released by plants.

See Green leaf volatile sensory calcium transduction in Arabidopsis by Yuri Aratani, Takuya Uemura, Takuma Hagihara, Kenji Matsui & Masatsugu Toyota and Insect Herbivory Selects for Volatile-Mediated Plant-Plant Communication by Aino Kalske, Kaori Shiojiri, Akane Uesugi, Yuzu Sakata, Kimberly Morrell and André Kessler.

Plant volatile organic compounds (VOCs) are major vehicles of information transfer between organisms and mediate many ecological interactions . Altering VOC emission in response to herbivore damage has been hypothesized to be adaptive, as it can deter subsequent herbivores, attract natural enemies of herbivores, or transmit information about attacks between distant parts of the same plant. Neighboring plants may also respond to these VOC cues by priming their own defenses against oncoming herbivory, thereby reducing future damage ...

Plants from populations that experienced selection by insect herbivory induced resistance in all neighboring conspecifics by airborne cues, whereas those from populations experiencing herbivore exclusion induced resistance only in neighbors of the same genotype. Furthermore, the information-sharing plants converged on a common, airborne VOC signal upon damage. We demonstrate that herbivory can drive the evolution of plant-plant communication via induction of airborne cues and suggest plants as a model system for understanding information sharing and communication among organisms in general.

See Microphones capture ultrasonic crackles from plants that are water-deprived or injured by Emma Marris.

I've heard some really amazing sounds in a forest! Maybe they were the plants arranging themselves into a phased array and talking to the animals: see Sound from ultrasound, Parametric array and Phased array ultrasonics.

A parametric array, in the field of acoustics, is a nonlinear transduction mechanism that generates narrow, nearly side lobe-free beams of low frequency sound, through the mixing and interaction of high frequency sound waves, effectively overcoming the diffraction limit (a kind of spatial 'uncertainty principle') associated with linear acoustics. The main side lobe-free beam of low frequency sound is created as a result of nonlinear mixing of two high frequency sound beams at their difference frequency. Parametric arrays can be formed in water, air, and earth materials/rock.

See Horizontal gene transfer.

Horizontal gene transfer is the primary mechanism for the spread of antibiotic resistance in bacteria and plays an important role in the evolution of bacteria that can degrade novel compounds such as human-created pesticides and in the evolution, maintenance, and transmission of virulence.

David Hestenes - Tutorial on Geometric Calculus

This is a very high-level overview, and not too technical, for the first fifteen minutes at least. It's about the relationship between mathematics and physics and development of scientific ideas. At 40:11 he shows how Structure and Interpretation of Classical Mechanics should have been written!

David Turner Obituary by Sarah Nicholas Fri 24 Nov 2023

This was in The Guardian: David Turner obituary , only eight days after I posted  David Turner Talking About Sixty Years of Functional Programming History : This talk was given in London in 2017: See  Turner, D. A. "Some History of Functional Programming Languages" also  John Hughes - Why Functional Programming Matters  and David MacQueen's talk at ICFP 2015 in  Numberphile - Sophie Maclean on the Catalan Numbers . At 10:30 This whole discussion abut combinator reduction is especially interesting. I didn't know Arthur Norman had tried building hardware for combinator machines. I'll look that up: maybe start here A.C. Norman  Faster combinator reduction using stock hardware  in LFP '88: Proceedings of the 1988 ACM conference on LISP and functional programming. At 26:25 on the ISWIM virtual machine implemented in the PAL compacting garbage collector?! This work Reynolds and others did was at MIT in Masecheusetts and Argonne National Laboratory Illinois. Did

See also  Laplace Transform : Algebraic construction The Laplace transform can be alternatively defined in a purely algebraic manner by applying a field of fractions construction to the convolution ring of functions on the positive half-line. The resulting space of abstract operators is exactly equivalent to Laplace space, but in this construction the forward and reverse transforms never need to be explicitly defined (avoiding the related difficulties with proving convergence).  Mikusiński
