“Blessed be you, mighty matter”*…

The existence of anyons was inferred from quantum topology — the novel properties of shapes made by quantum systems

 

Every particle in the universe — from a cosmic ray to a quark — is either a fermion or a boson. These categories divide the building blocks of nature into two distinct kingdoms… or so we thought.  Now researchers have discovered the first examples of a third particle kingdom…

Anyons, as they’re known, don’t behave like either fermions or bosons; instead, their behavior is somewhere in the middle. In a recent paper published in Science, physicists have found the first experimental evidence that these particles don’t fit into either kingdom. “We had bosons and fermions, and now we’ve got this third kingdom,” said Frank Wilczek, a Nobel prize–winning physicist at the Massachusetts Institute of Technology. “It’s absolutely a milestone.”…

As we examine existence, we might spare a thought for Roger Bacon; he died on this date in 1292.  A philosopher and Franciscan friar, Bacon was one of the first to propose mathematics and experimentation as appropriate methods of science.  Working in mathematics, astronomy, physics, alchemy, and languages, he was particularly impactful in optics: he elucidated the principles of refraction, reflection, and spherical aberration, and described spectacles, which soon thereafter came into use.  He developed many mathematical results concerning lenses, proposed mechanically propelled ships, carriages, and flying machines, and used a camera obscura to observe eclipses of the Sun.  And he was the first European give a detailed description of the process of making gunpowder.

He began his career at Oxford, then lectured for a time at Paris, where his skills as a pedagogue earned him the title Doctor Mirabilis, or “wonderful teacher.”  He stopped teaching when he became a Franciscan.  But his scientific work continued, despite his Order’s restrictions on activity and publication, as Bacon enjoyed the protection and patronage of Pope Clement…  until, on Clement’s death, he was placed under house arrest in Oxford, where he continued his studies, but was unable to publish and communicate with fellow investigators.

400,000 years ago, humans and Neanderthals discovered fire. This ignited a relationship between people and photons that changed the course of mankind—and continues to evolve to this day…

“It’s fine to celebrate success, but it is more important to heed the lessons of failure”*…

 

If you ever wanted a glimpse into what dooms startups, look no further than autopsy.io, a website that lists the reasons why many newborn tech firms imploded. The website offers entrepreneurs the ability to self-explain why their startup didn’t quite make it; in a bid to separate real-life stories from entertaining fictions, the application form asks for a link to a blog post or medium article “that tells the story of the failure,” along with the founder(s) Twitter handle and Crunchbase or Angel.co profile. Some of the reasons listed for failure are maddeningly opaque, such as UniSport’s “for a number of reasons” or PlayCafe’s “we didn’t reach enough users.” Others are bleakly hilarious; as the founders of Zillionears, self-billed as a “creative pre-sale platform for musicians,” confessed: “People really didn’t really LIKE anything about our product.” If you’re thinking of launching your own company, or you work for a wet-behind-the-ears startup, it’s worth scanning the list to see if any of these potential crises are brewing in your setup.
