SPEAKING SPIDER. “We're beginning to perhaps be able to speak the language of a spider.Scientists at the Massachusetts Institute of Technology have turned spider webs into music -- creating an eerie soundtrack that could help them better understand how the arachnids spin their complex creations and even how they communicate.” https://lnkd.in/dzyYUP5 View in LinkedIn

EXOTIC BEASTS. “We will discuss extremal and near extremal black holes. Extremal magnetic black holes are more stable than their electric counterparts, since unit charge magnetic monopoles are much heavier than electrically charged particles, and are thus harder to pair create. In addition, an electrically charged black hole can be neutralized in conductive medium, while a magnetically charged one cannot be neutralized with ordinary matter.” https://lnkd.in/dX6Fbwx View in LinkedIn

“A MAGNETIC BLACK HOLE is a black hole with a magnetic charge. It is a solution of the Standard Model coupled to gravity. So it can be viewed a type of magnetic monopole that does not require any new physics.” https://lnkd.in/dX6Fbwx View in LinkedIn

THE EDGE OF MATHEMATICS. “We discuss some properties of magnetic black holes in the Standard Model. These are solutions of the laws of physics as we know them, though they do not seem easy to produce.” https://lnkd.in/dX6Fbwx View in LinkedIn

EXTRAORDINARY LEADERSHIP. “New Zealand aims to create smoke-free generation. Proposals include making sale of cigarettes to anyone born after 2004 illegal. The plan will begin the final demise of tobacco products in this country.” I usually do not comment on politics, but this is different. https://lnkd.in/dNJBbAP View in LinkedIn

COSMOLOGY. “In the physical universe, the vector mode dies out fast due to the expanding spacetime. In the analogue gravity/cosmology situation addressed here, even though we are dealing with a contracting spacetime, we are at liberty to ignore the vector mode in the first place without altering the curl-free and non zero trace condition of χij.” https://lnkd.in/dusKMKM View in LinkedIn

A WORLD IN A GRAIN OF SAND. “The two scalar modes Ψ and Φ, relevant for cosmological observations in the physical universe, play an important role in the gravity analogue for granular matter. We fo- cus on the effect of external stress perturbations on the changes in the analogue spatial geometry.” https://lnkd.in/dusKMKM View in LinkedIn

SHEAR STRESS. “Clearly, the shear stress has been applied on an already spontaneously jammed isotropic state, to show that anisotropic structure formation results because of this external stress perturbation. This implies that, in the gravity analogue as per the Rachaudhuri equation, θ(0) < 0, so that we have a convergent geodesic congruence.” https://lnkd.in/dusKMKM View in LinkedIn

GRANULAR SAND. “Granular media are known to exhibit a richer variety of density fluctuations under externally applied stress, especially a shear stress.” https://lnkd.in/dusKMKM View in LinkedIn

RESPONSE TO PAPER. “As for reactions, it's really a mixed bag. We've had very positive reactions from a small number of young aficionados of granular matter, who've thought our proposed analogy as `very, very interesting'. On the other hand, senior experts appear to be much less enthusiastic and even skeptical. This isn't surprising, given that in today's world people are concerned about their own niches, and losing even an inch of their domain to a group of novices isn't welcome. The paper isn't published yet, but the fight with reviewers is on, so lets see. With our best wishes, Partha (Majumdar).” View in LinkedIn
