Field Guide Issue #011 The next major geopolitical crisis may not begin with a missile strike, but with a silent keystroke that shuts down a municipal power grid. By Santhosh Vishwamitra Definition Cyber warfare against critical infrastructure is the use of digital attacks to disrupt, degrade, or destroy the physical systems that keep a modern society functioning. Unlike traditional cyber espionage, which primarily seeks information or access, cyber operations against critical infrastructure can aim to disrupt physical processes, degrade essential services, or create wider societal and economic effects. The goal is not always to read a secret document. Sometimes the goal is to turn off the lights, stop the trains, or contaminate the water supply. Classification of Targeted Sectors Nations do not target infrastructure randomly. They focus on sectors where disruption causes immediate economic paralysis or public panic. Five major target categories illustrate whe...

Student Explainer Issue #012 Nations fight over the electromagnetic spectrum with the same strategic intensity as they once fought over oil fields, yet it has no weight, no physical location, and cannot be seized, destroyed, or physically occupied. By Santhosh Vishwamitra What This Explains The electromagnetic spectrum is the complete range of electromagnetic radiation, from extremely low-frequency radio waves to high-energy gamma rays. It is also one of the most strategically contested resources in modern geopolitics. This explainer covers the foundational physics, the band-by-band breakdown, the military uses, and the international governance battles that make spectrum control a matter of national power. In This Article The Geopolitical Paradox What Is the Electromagnetic Spectrum? Frequency, Wavelength, and Energy The Spectrum Band by Band Real-World Applications Electronic Warfare and the Spectrum as Battlefield ...

Vishwamitra Brief Issue #004  |  August 30, 2026 A glacier collapse on August 26 triggered catastrophic flooding across Nepal and Tibet. By August 30, hundreds were confirmed dead and nearly 3,000 people were reported missing.

Mystery Files Issue #011 A 72-second radio burst detected in 1977 matched many of the characteristics researchers have long considered promising in a candidate interstellar transmission, has never been detected again, and has never been adequately explained. By Santhosh Vishwamitra The peculiar thing about the WOW! Signal is that it becomes more anomalous with each passing year of silence, not less. Most scientific anomalies grow less surprising over time as new instruments, new data, or revised theory gradually dissolves the mystery. The WOW! Signal has done the opposite: nearly five decades of searching by some of the world's best radio telescopes have produced nothing resembling the original event, while newer research has introduced possible natural explanations without definitively closing the case. The Discovery The Big Ear radio telescope at Ohio State University was conducting a routine SETI survey on August 15, 1977. Because the telescope was auto...
