That's a misunderstanding of the bernoulli effect. It does not say moving fluid has lower pressure as some universal law. It applies to when fluid is moving through the same exact route, as in, inside a pipe or around an object. It does not have anything to do with pressure inside the car vs outside., as it's a massive, chaotic ball of turbulence where you get both inbound and outbound airflow at the same window or can do tricks to make one window inbound (rear windows) and one window outbound (front). If it were that simple, it'd still be hard to breathe on a motorcycle because your torso is somewhat shielded by the aerodynamics of the headlight/gauge area on a naked. Sport bikes often shield your torso as well, throwing air all at your head, which would cause the same "pressure differential" as the car example. But it doesn't, because that's not how it works.

The classic example of this misunderstanding is things like pump pressure/flow rate charts. Flow rate goes up, pressure goes down in the chart. Nothing to do with this principle, everything to do with the pump being a fixed-power device putting out a certain amount of work. It's more of a power vs torque thing than a fluid principle.

And no, air does not move around a wing/airfoil, speed up on the longer side, and reunute its former molecular siblings at the tail of the airfoil. That's a mythunderstanding, too. Nothing makes them meet up again.

That's a great point. You and I didn't just see how little they had, we saw how much they did with so little. Similar situation for me back home, parents were struggling working class. It re-lensed how little we did (do) with so much. So much more space, so much more money, so many more comforts, so much more entertainment, so much more healthcare, so many more protective regulations.

For what? What do we have to show for it?

It knocked me a tick towards nihilism or something for some time. It made me wonder how I can be so miserable when my life should be verifiably better than what I saw there. But I came back from that eventually, because having better baseline conditions doesn't mean life isn't a struggle. It scales to where you sit in the wealth rankings of your local society. The bottom is the bottom, no matter how you compare to other societies. But I've done better at appreciating what I have and maximizing what I do. I have the option to travel, to be entertained, to build, to create, to care, to relax, to be comfortable, to experience, to observe, to theorize. And that's what I'll continue doing because it's a privilege wasted otherwise.

For a couple years, the ChatBOT reliance was isolated to people I didn't trust for answers in the first place. But now I see it creeping into the circles I thought would never trust it. I just hope they're vetting anything beyond trivial information (but I mean, why blindly trust trivial information from a chatbot in the first place? You wanted the correct answer, didn't you?)

It's not like trusting Wikipedia. It's not like trusting an encyclopedia. It's not like trusting a textbook. All of those take a plethora of sources to write their articles, cite their sources, then publish a single, public article that anyone can review. ChatBOTs take unspecified sources, summarizes them, and provides you a private response that undergoes no review. The only way to confirm accuracy is to already know the facts. If you did, you probably wouldn't be asking.

That's maybe a weird way to go about it, but I don't see an issue with fact-checking in real time. I'm aware many other people don't like it, but I don't give a shit. If it's wrong, it's wrong. However, the source musslt be trustworthy and ChatBOT is not.

The article in your library/wikipedia/forum takes 10 contributors and publishes a single, public article for which all can see it. Chatbots take 10 contributions and summarizes them into a single, private article that undergoes no review whatsoever. If you don't already know the answer, you have no inclination as to what's true. It's nowhere near the same.

I've wondered if the Ultras in the Revelation Space novel series were ever regretful of their modifications. They generally modified themselves to extremes to be better than any normal human, something of note in a universe where most humans have biological repairs to extend their lives hundreds of years as it is. I can't remember if they tended to be all-white or if I'm just picturing their usual ships, the lighthuggers (near-lightspeed ships). I do remember they often have dreadlocks and grow a new lock for each reefer sleep (interstellar cryostasis), so that fuels my mental image that half of them look like The Twins of the Matrix

It's a cool series. It sets you up with a ton of universe expo. It does not exactly pull it all together.

I've been fleshing out some naturalist motif of a skull on a pike wrapped in ivy growths. Or on a staff. Maybe with a snake, in homage to the Rod of Asclepius. Figure it's a good forearm piece.

Or a bird. It always comes back to birds. There's just a bird for every feeling. A peregrine in a dive, a phoenix taking its throne, a blackbird living life, a raven brooding, an owl observing, a hawk soaring, a seagull eating French fries, a vulture scavenging, a hummingbird hovering, a parrot shouldered, so many options.

Depends on how you define $250,000 in cash. Way more than the average American has on hand, not exactly a crazy amount to have if you don't spend it on a bigger house and expensive car as soon as you can and save your kid's college fund. It's a hefty sum, but people comment like she's a forgotten Rockefeller.

People whose only exposure to her music is the radio hits and people who were never a teenage girl are the ones complaining about her music. If you don't get it, that's fine. Its not for you. It's not for me.

Lady Gaga has done the same thing yet gets a fraction of the hate. Radio bangers fund the real artist.

Biden derangement syndrome? He's complaining a past president didn't do anything for a current event

Well shit, I missed that update 7 months ago.

It's certainly a topic of interest to me, but I'd like to avoid the "spaceship pyramid" levels of conspiracy and the meatless text-to-speech summaries that will inevitably appear in my suggested feed(s). I thought I'd find it by now, given my feed has plenty of planes. I know it's a distraction, but I may as well be entertained while I continue waiting for the yanks to release the real files we're asking for.

I'm afraid AI has surpassed me, as I still can't draw hands. Seriously though, I miss doodling all through school. I don't know where that free creativity has gone, but I'm working to bring it back. Some early jobs left me in a dark rut, but I've settled into a decent job, a career even, and feel a certain mental calm and freedom trickling in.

I was aiming for something resembling a pose often struck by St Michael in depictions of him defeating demons. I don't have a goal for the actual identity of the figure, nor what they're doing. Ultimately, I want it to be triumphing over something. The end goal is to explore ideas for a tattoo. It already worked beautifully once, where I took a crude drawing to an artist with a style I liked, then watched them bring it to life with more talent and their own flair. I picked the elements, laid the composure, and outsourced the details to an amazing artist. What better meaning to a tattoo than "I basically made this"? With any luck, lightning will strike twice... Or more.
