Once again we are at the crossroads of technology and its limits. In the future, you will talk to someone from a Moon base, but wait! … There will be a 3 second delay. The speed of light (or internet, telephony, messaging, video) is a huge barrier in space communications. Mars is 3 light minutes… Read more »

‘Scientific Paradoxes’ in the SARS-COV2 Pandemic
A 1994 paper by the geographer-physicist duo, Gould & Wallace (https://www.tandfonline.com/doi/abs/10.1080/04353684.1994.11879669 ) showed the mistakes of traditional epidemiologists in understanding the spread of AIDS due to their focus on the continuous time series differential equations and not on the spatial heterodoxy of quantized spatial jumps in AIDS diffusion. A quarter century later, with enormous progress… Read more »
Explosive Quarantine: A novel approach to spatial quarantine
Explosive percolation (https://science.sciencemag.org/content/323/5920/1453) is a recent concept where random networks R0 (basic reproductive number) is reached abruptly. When R0 crosses 1.0 there is complete connectivity (a network of nodes and links are completely connected; #nodes = #links makes R0 =1 because R0 = #nodes/#links). This 1912 paper https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3320609/ shows the first evidence of mathematical modeling… Read more »
SPDEs & Point processes
It would be useful to provide an update on the latest in spatial point pattern analysis. For national grants etc. the ball has moved for spatial point analysis from geary-g stats etc to SPDEs (Stochastic Partial Differential Equations) implemented through INLAs (Integrated Nested Laplace Transformations). It all sounds very math-y but it’s quite easily… Read more »
A Trillion DOS
Tell us about your idea: “1 Trillion Drone Trips!” I presented this idea at the ‘Internet of Things Symposium’ held at Indiana University in April 2019. Imagine: your friend 3 miles away made an amazing cocktail and sends you a sample for your opinion? Or, in 2050, a grandma wants an elephant shaped… Read more »
