My impression is that there are a lot of geeks out there who want the Star Trek holodeck, and they see VR and generative AI as a way to get there. But they ignore all the episodes that explored the ways such a technology could be harmful, s

The "cold copper" accelerator technology is really neat, in my opinion. The way particle accelerators work is that they pump RF through waveguides into cavities, such that the electric field pushes on the electrons right as they e

I don't remember it that way. I took it more more as being about the definition of "fish", and demonstrating that whalers don't think about things the same way that non-whalers do. It's not ignorance; he acknowledge

I don't think it's anything so interesting. The FM band starts at the round number of 88.0 MHz and ends at 108.0 MHz. To divide that evenly into 200 kHz channels without bleeding over the ends of the band, they have to be centered

There's no climate scenario in which Mars is more habitable than Earth. Even if a Texas-sized asteroid crashed into Earth, Earth would still be more habitable than Mars.

> Taking a public asset and reserving it for exclusive use by certain individuals is not right: Thats a fancy way of saying: parks are not campgrounds. These types of policies are plain wrong, and cities should know better by now. How do

I think it's at least plausible that ADHD traits could have been useful in the hunting and gathering environment humans evolved in. Being more inclined to pay attention to new things in your environment might make you more likely to di

I keep a daily log where I scribble down some basics of what I did that day. At the end of the week, I go through that, consolidate it into a few things I did that week, and add it to a git repo. When I need to do performance reviews or som

2016 might be the most clear one. Hamilton and Rosberg were both driving for Mercedes. In 2021, Hamilton nearly won it in his Mercedes despite Red Bull having the better car for most of the season. The thing is, the teams putting in the mon

In Vernor Vinge's A Deepness in the Sky , ships in the far distant future are still counting time from the Unix epoch. The common belief in the novel, though, is that it's measuring time from when humans first became space-faring

The closest thing left is the monthly Electronics Flea Market ( https://www.electronicsfleamarket.com/ ). The next one is this weekend (July 14). It doesn't have the volume or the variety that HSC did, but there's s

On the other hand, there are plenty of people who worked hard and still failed in business due to bad luck. This article is pure fluff.

Also e-ink displays. For most of the ebooks I've read recently, the images end up posterized to the point of near illegibility.

No, the comment you're replying to is confused. These gyroscopes are entirely used for determining Hubble's orientation. Reaction wheels effect the actual rotation, and Hubble's are fine. I think the confusion is a result of

I got one for the winter, and it was fine for getting a little extra exercise. Now that it's summer, I'd rather go outside. I found I could only really use it when I was watching something on the screen. Watching videos was fine,

My assumption has been they do that when the shipment is damaged or lost. And that they haven't implemented any sort of automatic refund or reship because some percentage of people don't notice, and that reduces Amazon's loss

Do you drink alcohol in the evenings? Alcohol has a sedative effect at first, but your body compensates and so you'll tend to wake up when the alcohol wears off, rather than when you're fully rested.

I've walked out of an interview when the employee doing it took a phone call in the middle of it. It was so rude and disrespectful. I once got a whiteboarding problem and proposed a solution, and the interviewer gave me a flat out &quo

My experience has been that "spin off" CEOs are often there only so they can check a "CEO experience" box in the hope that it will help them climb higher in the larger corporation. This leads to all sorts of bad decision

Gravity can be modeled as "things on the earth's surface accelerate downward at about 10 m/s², regardless of their mass". This works very well. Gravity can be modeled as "planets orbit the sun according to Kepler&#x

I used to work in neutrino physics, and I will consider myself lucky if I see a detection of the cosmic neutrino background in my lifetime (roughly the next 50 years).

The more interesting one was the Klapdor-Kleingrothaus claim of observing neutrinoless double beta decay in germanium 76 in the early 2000s. That was a major impetus for the generation of double beta decay experiments like this that ran in

by SaberTail 2y ago
Yeah, they didn't observe the decay, but set lower limits on the half life of the decay, which translates into upper limits on a neutrino mass. Next time will mostly involve getting more germanium 76, but also improving the techniques

That was Starlink. The satellite tracking app I have predicted it pretty much perfectly. There was a launch out of Vandenberg early Wednesday, just after midnight. My guess is that it was so bright because the satellites haven't really

When counting photons, the noise in your signal scales with the square root of the total count. If the satellite is dumping 100 ± 10 photons in every pixel it passes through, you can no longer distinguish objects so faint that they'd o

The difficulty with "clean fusion bombs" is that bomb makers can always increase the yield of a fusion bomb by making it dirty. Fusion releases neutrons, and these neutrons have enough energy to fission the common 238 isotope of u
