PLANT ROOT ARCHVE. “Digitized by the Wageningen University & Research, the extensive archive is the culmination of 40 years of research in Austria that involved cultivating and carefully retrieving developed plant life from the soil for study. It now boasts more than 1,000 renderings of the winding, spindly roots, some of which branch multiple feet wide.” https://lnkd.in/eN8QNYFd View in LinkedIn

PUFFY DM “been shown to be successful in explaining observations across a wide range of mass scales spanning dwarf galaxies of the THINGS sample, low-surface-brightness spiral galaxies and clusters of galaxies including the Bullet Cluster. It remains to be seen if MDM enjoys similar successes but the prospects look promising.” (MDM = Modified Dark Matter). https://www.mdpi.com/1099-4300/21/11/1035/htm View in LinkedIn

LINKING BACK. “On the other hand, we can heuristically argue that MDM may enjoy similar properties as DM that are known to have finite size (and hence, in a way, extended).” (MDM = Modified Dark Matter; DM = Dark Matter). https://www.mdpi.com/1099-4300/21/11/1035/htm View in LinkedIn

NEW TERRITORY. “MDM as Puffy Dark Matter. MDM quanta obey infinite statistics. Hence they are extended and the well-known tools of effective field theory are inadequate. How they interact with ordinary matter and how they self-interact remain to be investigated.” (MDM = Modified Dark Matter). https://www.mdpi.com/1099-4300/21/11/1035/htm View in LinkedIn

THE HOPE. “This may explain why MOND does not work well at the cluster and cosmic scales, whereas MDM works at both the galactic and cluster scales and is expected to be completely compatible with cosmology.” (MOND = Milgrom’s theory of modified Newtonian dynamics; MDM = Modified Dark Matter). https://www.mdpi.com/1099-4300/21/11/1035/htm View in LinkedIn

OLD FAILINGS. “If we naively use MOND at the cluster or cosmic scale, we would be missing the pressure and cosmological constant terms, which could be significant.” (MOND = Milgrom’s theory of modified Newtonian dynamics). https://www.mdpi.com/1099-4300/21/11/1035/htm View in LinkedIn

The first spring violets in Girona, including the uncommonly seen white violet. The longer photoperiod is also engorging the reproductive readiness of the birds, who are entering an uproar of chorus. View in LinkedIn

“NATURE is the most powerful narcotic I've taken, and Purple Emperor should be declared illegal (Class A1).” (British naturalist, Matthew Oates, good friend for 60 years, personal communication). https://lnkd.in/eWESdTsC View in LinkedIn

TOO MUCH NOISE. “But when the proper averaging is carried out (even if there is such a formalism), now it appears (at least to this author) that the fluctuations are perhaps too small to be detectable with the currently available experimental and observational techniques. Nevertheless, let us briefly discuss several of the proposals to detect spacetime foam.” https://www.mdpi.com/1099-4300/21/11/1035/htm View in LinkedIn

MEASURING FOAM. “There have been numerous proposals to detect spacetime foam, involving astronomical high-energy gamma ray observations of distant gamma-ray bursts and distant quasars, gravity-wave interferometers and atom interferometers and so forth.” https://www.mdpi.com/1099-4300/21/11/1035/htm View in LinkedIn
