Scientists may have seen #darkmatter. If they did, what exactly is it?
On September 1, scientists with the LUX-ZEPLIN announced they’d seen signal could have been caused by a single particle of dark matter — though it could still be caused by known #physics processes.
Interest has focused on a #particle called a #higgsino. “If we discover it, it would be the first discovery of #supersymmetry,” says theoretical physicist Harikrishnan Ramani

Ice Melting Dynamics Under Rotation
When it comes to understanding planetary systems, it’s often critical to capture more than one physical effect. Here, the UCLASpinLab demonstrates how a combination of rotation and salinity affect ice melting. You can think of this as a miniature version of an iceberg melting. The rotating tank mimics the Coriolis effect real icebergs are large enough to feel from Earth’s rotation.
In fresh water, the ice’s meltwater creates a cold, dense plume that sinks, forming a column beneath the ice. In contrast, an identical ice cube in salt water forms a layer of meltwater at the surface because it’s lighter than the surrounding salt water. Very different results for two systems that are largely identical! (Video and image credit: UCLASpinLab)

FUN FACT: The sunlight hitting Earth in an hour packs enough energy to power every kettle, car, and charger on the planet for a year. But there's a catch: we're not giant solar panels.
The scale kicker? We'd need a continent-sized solar cell to capture it all. And unfortunately, we haven't quite parked one in orbit yet.
Meanwhile, 31,453 objects are tracked in orbit as we continue harnessing these cosmic details.

A Modern Handbook of Physics – B.M. Yavorsky, A.A. Detlaf (LaTeX Version)
ScreenshotIn this post, we will see the LaTeX version of a great resource in physics:
A Modern Handbook of Physics by B. M. Yavorksy and A. A. Detlaf.About the book (From the Preface)
The basic sciences and physics, in particular, are of prime importance today in the training of engineers for the various branches of the national economy. This has led to fundamental changes in recent years in the teaching of physics in engineering institutes, and to the students of other educational institutions in which they do not major in physics. The scope and scientific level of physics courses have been substantially supplemented and cover the main trends in the development of modern physics. Consequently, the physics textbooks for engineering students have inevitably become three-volume editions of almost fifteen hundred pages. The need has arisen, in this connection, for a concise handbook on this subject.
The aim of the authors was to fulfill this need. In scope and depth this handbook includes all of the definitions, formulas and information covered in the most comprehensive and up-to-date physics courses of engineering institutes
and the physics departments of universities and colleges. Physical laws are concisely formulated, all the necessary explanations are given and, in many cases, derivations as well. Though it plays a vital role in the teaching of physics, experimental material has been omitted. This is due only to a lack of space. All the units and symbols comply with the requirements of the SI Units of physical quantities and systems of units are listed and dealt with in a short appendix.This handbook is designed primarily for engineering students, as well as college and university students studying, but not majoring in physics. It can be used to advantage by engineers and graduate students, as well as by instructors and lecturers of intermediate schools and colleges.
Mathematical knowledge required in using the handbook is within the scope of the ordinary mathematics courses of engineering institutes. The detailed index and the numerous cross references, indicating the chapter, section and subsection, are of aid in finding any required information.
The book was translated from the Russian by Nicholas Weinstein and was published by Mir in 1982.
Some snaps from the LaTeX edition…

Note: It took me a while to typeset this one. I had started it a long back in 2020, and continued in breaks. This is a long book – almost 1000 pages with eight parts and 43 chapters! At times it felt as if the book will never be completed, it took me on and off more than six years to complete (the first commit is in 2020!, see the screenshot below). The book was essentially complete in June last year, with only few minor tweaks remaining (essentially the margin placements of captions and diagrams) and diagrams to be redone in vector graphics. I have done a few initial ones into SVG, but then I sort of left it. I have not added the appendices and index. May be some time in the future we will have a release that has all diagrams as vector images.
Commits from Sep 2020 to Sep 2026
But anyways, finally here it is. Hope this is useful to all the readers.
PS: Though I have checked (and rechecked), I am sure there will be errors in the typesetting. Do tell if you find any (I am sure you will.) – Damitr
You can get the book here and here.
This book is an Open Educational Resource OER
Released under CC BY NC 4.0
PPS: In the works is Handbook of Elementary Mathematics by Vygodsky (and two textbooks by Irodov), I had real pleasure in typesetting some of the pages there. Hopefully we will see this perhaps before the year end.

Alright, future engineers!
**Newton's 2nd Law:** Net force equals mass times acceleration (`F_net = m * a`). It describes how forces cause motion.
Pro-Tip: `F_net` is the *vector sum* of ALL forces. Always use a Free Body Diagram to find it correctly!

Dangers of UFOs?
UFOs get more dangerous as we learn more about what they are or could be. The Angry Astronaut explains what might be the cause of the reported symptoms that are related to radiation poisoning.

I wanted to share the Xploration Station episode about the fact that there is no hard proof that the UFOs are more than unknown Earth aircraft.

Summary of Video TranscriptThe video presents a forensic analysis of three declassified DIA documents examining theoretical UAP propulsion systems and their physiological effects on humans. The central thesis is that advanced aerospace engineering, not magic or spiritual phenomena, explains anomalous flight observations.
Key Document Analysis:
- Dr. Christopher Green’s Medical Briefing – Investigates “anomalous acute and subacute field effects” reported by witnesses near UAPs. Claims include migraines, hair loss, neurological disruption, thermal burns, and cellular damage from unshielded high-energy fields rather than alien weapons.
- Inertial Electrostatic Confinement (IEC) Fusion – Explores using concentric electrostatic grids to pull fuel ions together without massive magnetic confinement. Produces intense RF/X-ray emissions that could cause the documented biological trauma.
- Positron Propulsion – Analyzes matter-antimatter annihilation as an energy source. Highlights the extreme radiation hazard: 511 keV gamma rays pass through human tissue, requiring shielding so heavy it destroys practical mass-to-thrust ratios.
Core Argument: The video argues that any craft executing Mach 20 right-angle turns or rapid atmospheric entry must concentrate astronomical energy in a small volume. Physics demands this creates unshielded radiation fields that produce exactly the biological injuries documented in military files—thermal burns, neural damage, and cellular breakdown.
The presenter concludes these crafts follow the same unforgiving thermodynamic realities as conventional aerospace engineering. The “miracles” attributed to UAPs are actually signatures of extreme unshielded propulsion systems operating at energy densities that make human biology vulnerable.
Advanced AI Scientist Analysis & Insights
On Propulsion Physics: The IEC fusion concept is theoretically sound but faces practical challenges: maintaining ultra-high voltage differentials across nested grids without arcing requires exceptional insulation materials and power management. The positron annihilation argument highlights a fundamental constraint in any advanced propulsion system—energy conversion inherently produces byproducts (heat, radiation) that must be managed.
On Shielding Trade-offs: The mass-to-thrust dilemma is real. Even 1 meter of lead weighs ~8,000 kg/m². For an aircraft requiring high acceleration, shielding becomes structurally prohibitive. This suggests either:
- The craft operates at significant distances from humans during active thrust phases
- Advanced materials (metamaterials, active shielding) could reduce mass while maintaining protection
- The “unshielded” nature is a design choice prioritizing performance over safety
On Energy Scaling: The transition from chemical rockets (~3 MJ/kg specific energy) to fusion (~10¹⁴ J/kg) and matter-antimatter (~9×10¹⁶ J/kg) represents orders of magnitude increases. The engineering challenge isn’t the energy itself but managing its release rate without catastrophic thermal or radiative feedback.
On Biological Effects: The biological damage described aligns with established physics: microwaves agitate water molecules, gamma rays ionize DNA, and intense EM fields disrupt neural signaling. This is consistent with industrial radiation safety protocols we apply to power plants and medical facilities—just scaled up dramatically.
Futurist Perspective: If these propulsion systems become viable, the primary engineering challenges will be:
- Power generation at required scales without excessive mass
- Radiation shielding that doesn’t violate aerospace mass constraints
- Thermal management during thrust operations
- Control systems capable of managing highly non-linear energy conversion
The “alien technology” narrative often obscures the fact that extreme physics problems are still engineering problems—just with higher stakes and fewer solutions available today.
