  • This Algorithm Just Solved One of Physics’ Most Infamous Problems
    Using an advanced Monte Carlo method, Caltech researchers found a way to tame the infinite complexity of Feynman diagrams and solve the long-standing polaron problem, unlocking deeper understanding of electron flow in tricky materials.
  • A simple twist unlocks never-before-seen quantum behavior
    Scientists have discovered a revolutionary new method for creating quantum states by twisting materials at the M-point, revealing exotic phenomena previously out of reach. This new direction dramatically expands the moiré toolkit and may soon lead to the experimental realization of long-sought quantum spin liquids.
  • Scientists just recreated a 1938 experiment that could rewrite fusion history
    A groundbreaking collaboration between Los Alamos scientists and Duke University has resurrected a nearly forgotten 1938 experiment that may have quietly sparked the age of fusion energy. Arthur Ruhlig, a little-known physicist, first observed signs of deuterium-tritium (DT) fusion nearly a decade before its significance became clear in nuclear science. The modern team not only […]
  • This breakthrough turns old tech into pure gold — No mercury, no cyanide, just light and salt
    At Flinders University, scientists have cracked a cleaner and greener way to extract gold—not just from ore, but also from our mounting piles of e-waste. By using a compound normally found in pool disinfectants and a novel polymer that can be reused, the method avoids toxic chemicals like mercury and cyanide. It even works on […]
  • Self-lighting chip uses quantum tunneling to spot a trillionth of a gram
    Imagine detecting a single trillionth of a gram of a molecule—like an amino acid—using just electricity and a chip smaller than your fingernail. That’s the power of a new quantum-enabled biosensor developed at EPFL. Ditching bulky lasers, it taps into the strange world of quantum tunneling, where electrons sneak through barriers and release light in […]
  • Scientists freeze quantum motion using ultrafast laser trick
    Harvard and PSI scientists have managed to freeze normally fleeting quantum states in time, creating a pathway to control them using pure electronic tricks and laser precision.

Sorting Vallejo Paints with Machine Learning

This article explores how to visually sort color collections using both statistics and machine learning. After experimenting with PCA for dimensionality reduction and simple color ordering, I shifted to XGBRanker, a machine learning method that learns personalized color preferences. By comparing these approaches, I aimed to find a method that ...

Semiconductor Packaging Technology

Wire bonding and flip-chip packaging represent two fundamental approaches to chip interconnection. While wire bonding offers simplicity and cost benefits, flip-chip allows higher density and faster signals. Adhesive and solder-based methods help balance thermal expansion and reduce stress. The industry continues shifting toward compact, high-performance packaging formats.

Electron Paramagnetic Resonance spectroscopy

Electron paramagnetic resonance (EPR) spectroscopy, also called electron spin resonance (ESR), is a technique for studying materials with unpaired electrons, such as organic and inorganic radicals, and transition metal complexes. It functions by detecting magnetic properties of electrons. This post covers the science of EPR, its key components, real-world applications, ...

Einstein, Politics and Science

The first world war (WWI) started in august 2014, and the German army proceeded very fast through Belgium. This rapid progression created a problem in the cities that were already captured, as the main army moved on to other locations. Harsh measures were taken to avoid any kind of resistance. ...

History of Physics (1895 – 1945)

Physics has always been an interesting topic, but it was during a span of only 50 years that physics completely changed the world. The movie "Oppenheimer" showed in great detail the history of what happened and how they got to the atomic bomb. But this is only part of the ...
