39 minutes. It may not seem like a lot, and obviously compared to the computer you’re reading this on, working for 39 minutes sounds kinda lousy. But in terms of quantum computing, it’s a big, big, big deal. That’s how long scientists were able to hold a qubit’s memory state for, which is way longer than anyone had previously been able to accomplish.
Despite Albert Einstein being a pretty damn big deal in his day, there are few recordings of him actually speaking. Lots of photos of him being a genius doof, but not much audio recordings of him talking trade. But in the fall of 1941, Albert Einstein gave this extraordinary reading of his essay “The Common Language of Science” to the British Association for the Advancement of Science.
In 1848, by then a nationally celebrated poet, Edgar Allan Poe published ”Eureka,” a 150-page prose poem on the nature and origin of the universe. The work, an overheated grab bag of metaphysics and cosmology, was a flop. A reviewer for Literary World likened it to ”arrant fudge.” A hundred years later T. S. Eliot summed up the critical consensus. ”Eureka,” he wrote, ”makes no deep impression … because we are aware of Poe’s lack of qualification in philosophy, theology or natural science.”
For all the fuss Hollywood likes to make about fusion reactions and “cold fusion”, as of yet, no one has been able to cause a fusion reaction that doesn’t cost way more than it produces, making it really impractical. But at the National Ignition Facility here in the great ol US of A, scientists did finally manage to yield a net positive fusion reaction with a whole fuckload of lasers.
As one test to look at the current technical feasibility of a future technology like teleportation, physics students at the University of Leicester have calculated that as far as we know, with current science and possible technology, you could teleport your entire being somewhere maybe, but that on the receiving end, it could take somewhere around about a quadrillion years to download all of your data.
However, that’s with what we currently know, and damn if science doesn’t keep surprising me every day with learning more about how the universe works. So hopefully one day, we might figure out some law of physics that would allow near instantaneous transfer of a person from one place to another.
For decades, Star Wars fans have speculated on how exactly one would make a lightsaber, and most ideas based on current scientific knowledge center on some sort of energy or plasma field. However, that was before scientists at Harvard and MIT changed everything. By enticing photons magically to cling together like molecules, they created a new form of matter. one that could be the basis of some kind of future lightsaber technology. Even though they acknowledge this could one day be used to create lightsabers, the scientists say their first priority is quantum computing. It’s always fucking quantum computing.
Every good attempt to try and reign in the weird world of quantum physics has so far met with mixed results, but the discovery of a multifaceted, multidimensional geometric shape at the heart of quantum physics may make things a little more predictable. And it would even make the ancient Greeks get a boner in their togas, considering how big they were on beautiful geometry being the basis for everything.
There’s a lot to summarize, but the above shape is called an amplituhedron and in its geometry are all the probabilities of particle interaction.

Richard Feynman will be forever famous not just for his direct contribution to the sciences, but for his amazing lectures, which made physics engaging and accessible to a wide audience. CalTech recently released volume one of his physics lectures for free online with more to come in the future.
There are some accepted theories for where all the energy came from that powered the Big Bang, but there’s a lot of room for speculation. One theory that’s been making the rounds is that our universe is a three dimensional shart out of the anus of a four dimensional black hole. Or something to that effect.
Physicist Art Hobson has offered a solution, within the framework of standard quantum physics, to the long-running debate about the nature of quantum measurement.
In an article published August 8 by Physical Review A, a journal of the American Physical Society, Hobson argues that the phenomenon known as “nonlocality” is key to understanding the measurement problem illustrated by “Schrodinger’s cat.”
