Making matter from light – ultra energies and unification of forces

E = mc² The Holy Grail of modern physics is a so-called theory of everything, a unified field theory, a theory which unifies all known “forces.” That is, unifies all the fundamental interactions of nature. The three “quantum” interactions (electromagnetism, weak, strong) and gravitation. A conventional sequence of theories depicts final unification as occurring at… Continue reading Making matter from light – ultra energies and unification of forces

Sightseeing near the speed of light – realistic simulation

Paraphrasing: Just a note before you go,A vision to be learnedTraveling near the speed of lightIt’s easy to get … Imagining how things would look when traveling near the speed of light is an interesting exercise. Using a freeware video game developed by MIT Game Lab (2012), this visualization (below) by The Action Lab is… Continue reading Sightseeing near the speed of light – realistic simulation

Quantum mechanics math basics – tasting the notation

[Communicating science series] All hail vector spaces! Imagine walking into an elementary school classroom and finding kids talking about quantum states. Depicting quantum interactions using diagrams and bra-ket manipulatives, for wave functions. Someday, eh. While we may never achieve Ernest Rutherford‘s notion of a quantum theory so simple that we can explain it to an… Continue reading Quantum mechanics math basics – tasting the notation

DUNE – digging for neutrinos, not spice

[Big Science, quantum foundations] While already following this Big Science project [1], with construction underway (for the next 3 years), I felt that a specific post was appropriate. The Deep Underground Neutrino Experiment (DUNE) is a massive worldwide collaboration between countries, organizations, and over a 1000 scientists. All hail neutrinos! [2] I spent some time… Continue reading DUNE – digging for neutrinos, not spice

Quest for room temperature superconductivity

[Placeholder] [Draft] This is a topic which I’ve followed for decades. A holy grail of physics: room temperature superconductivity. The physics of Cooper pairs: what makes two electrons pair up when their charge actually makes them repel each other? SciTechDaily > “Breakthrough in Understanding the Physics of High-Temperature Superconductivity” by Helmholtz-Zentrum Dresden-Rossendorf (May 12, 2020).… Continue reading Quest for room temperature superconductivity

Black hole systems – communicating the cosmos

[Communicating science series] Today my post celebrates another science communicator, Fraser Cain, and his YouTube channel by the same name. This week, I noticed his video “Two Supermassive Black Holes Orbiting Each Other. Stephen Hawking Was Right!” (May 11, 2020). Well-done visualization. His channel description says: Space and astronomy news from Fraser Cain, publisher of… Continue reading Black hole systems – communicating the cosmos

A shelf life for the universe?

While Sean Carroll’s latest chat-from-home presentations on his YouTube channel address the “biggest ideas” in the universe, other theoretical physicists explore whether our mind-boggling big universe has sort of a shelf life. A final reservation date, so to speak, at a fantastically socially-distanced restaurant at the end of the universe. Reference: Forbes > “What Will… Continue reading A shelf life for the universe?
