This article is about two galaxies which we are seeing as they appeared 300-400 million years after the big bang (over 13 billion years ago). Those galaxies are magnified to the point where they are visible by another, much closer galaxy cl

Same here - the games just randomly end, sometimes my clock gets set to 0 out of nowhere, sometimes the opponent's. Fun game though!

I met Ellsberg when I attended a live recording of the podcast Philosophy Talk in 2019. It was called "The Doomsday Doctrine", it was about the policy of mutually assured distruction. I remember he talked about the difference betw

My bet continues to be optical phenomena - that's why the orbs and other phenomena resemble simple geometric forms, rather than anything with complex structure, service irregularities, etc. Happy to be proven wrong, as this is the most

By the way, the word is "beeline", not "b-line". It originally was a reference to bees traveling back to their hive. Sorry to be pedantic.

Real qubits have flaws, and you could experiment to see under what conditions they work better or worse, like by applying magnetic fields. Simulated qubits are presumably flawless, and so you can't experiment with them.

They seem to be marketed for educational purposes. You could simulate them in software easily. They could be useful for research, but they're not directly useful for computing, except as a novelty.

That pattern looks periodic, but it's super cool! I think the periodic unit is a flower shape consisting of 8 tiles: 2 in the middle making a hexagon, and then 6 more around the hexagon, like the petals of a flower.

Your reaction should be "astronomy fun fact, that will have no direct effects on anyone's life." This black hole is so dim and distant that it required a super powerful telescope to even notice it exists. It will have no effe

They mention that "The water ice was first chilled in liquid nitrogen to minus 320 degrees Fahrenheit" (77K). The paper mentions that the new phase of ice reverts to something less interesting when heated to 140K (-207F).

Given that "The water ice was first chilled in liquid nitrogen to minus 320 degrees Fahrenheit" (77K), I think it would taste like frostbite. The paper mentions that the new phase of ice reverts to something less interesting at 14

These videos just look like optical artifacts of the lenses of the cameras, as discussed here: https://youtu.be/jHDlfIaBEqw Is there any evidence that there's more to these videos than that?

This definition fails because Q-bar needs to be a subset of Q, but in Q-bar, the graphs T1, S2, and T2 are specified to be the single-edge graphs e1, e2, e3. But single-edge graphs are not in Q.

While an M/M/n is a good starting point, there are several extra important features to capture. First, many of these applications have a load-balancing step, where arriving jobs are dispatched to queues at each of the machines. Th

The only thing we use processing time for in the Nudge paper is to classify jobs as "Large", "Small" or "Other". If instead of exact processing times, we had estimates, the result would still work as long as a

Thanks for the question! For thinking about bursty arrivals, a good rule of thumb is to look at the variance of the inter-arrival times. The key number is the variance of interarrival times divided by the mean interarrival time squared. The

This article describes pretty much exactly why I turned to Rust for my scientific computing - high speed, far easier to use than C or C++, less bug prone.

There is something to that - there's a concept called "Quantum Nonlocality", which says that an accurate description of an entangled quantum system must be nonlocal - to predict what will happen, we need to look at the whole
