Chicken Parmesan is what happens when you take Italian people and put them in America. You take Italians, with the cooking methods they know, their tastes, and set them down in 19th century New York, they make Chicken Parm. This is a well-tested hypothesis.
What’s your point?
You mean to tell me you were confused by a place named “Ontario, CA”? How?
Might it have anything to do with the fact nobody knows what the hell givesendgo is?
The United States is a federation.
Each state has a code of laws, and the federal government has one. You break a state law, you’re going to state court. You break a federal law, you’re going to federal court. You break a state law and a federal law, you’re going to state and federal court.
Nah. We’re diversified. We’re always trying out new and exciting forms of crime. And we’d better, because there’s some Japanese gangs out there that’s gonna do it faster and cheaper.
Rarely. And I’m a ham.
Humans have flown a total of ten manned missions that involved a Hohmann transfer: Apollo 8, Apollo 10-17, and Artemis 2. All ten flew to the Moon. On a typical Apollo mission, the outward bound coast leg is about 72 hours, between TLI and LOI, during which time they had to do the release-turn around-dock-extract maneuver with the lunar module and do at least one course correction.
We’ve been wasting tax payer dollars for more than half a century now designing and redesigning manned Mars missions that aren’t ever going to fly. Some of the various “artist’s conceptions” over the decades have included various centrifugal gravity solutions, be it the wagon wheel type or the bolas type or whatever. I don’t believe any actual hardware has even begun construction. Before you start worrying about that, you’ve got to 1. have a society healthy enough to fly manned deep space missions, and 2. figure out how to shield the crew from radiation first. Neither of which we have figured out at the moment.
Because the constant rotation complicates things a lot.
Specifically talking about the International Space Station, its main mission is a microgravity laboratory. We put it up there so we can learn about microgravity. Why go through all the expense of putting it up there and then spinning it to make gravity when we get it for free down here on the surface?
As for other craft? We have yet to develop manned spacecraft that can do the duration where it would be worth doing. Even the longer Apollo missions were in space for a whopping two weeks and 2/3 of the crew still landed, got out and stretched their legs. It hasn’t been worth the engineering hassle to do it.
And it is an engineering hassle, because…
The ship has to be designed to handle it. It’s under additional stresses, so it’s got to be built tougher to handle it. That’s added weight, and just typing that sentence made at least three rocket scientists cringe to death.
Humans actually aren’t great at living in a spin gravity environment. The smaller the radius of the spin, the worse it gets. For one thing, in a centrifuge, there’s a pretty steep gradient in centrifugal/centripetal/pedantic force, the farther toward the rim you are the greater the gravity. For very small distances that can be significant enough to cause problems on its own. But also, spinning humans isn’t good for their vestibular systems. Each of your inner ears has three semi-circular canals filled with fluid, and little hairs that can detect the movement of that fluid. This allows you to sense rotation around three axes, kind of like a gyroscope sensor. This evolved in an environment that rotates a 1 rotation per day, functionally stationary. Spin a human at several RPM and that constant rotation is enough to start throwing off balance, causing nausea etc. So the bigger the radius of the spin, and the slower, the better. That takes more weight, and there go three more rocket scientists.
It makes the spacecraft a pain to handle. You need to be able to orient spacecraft in space to point engines, windows, instruments, docking adapters etc. in various stable directions. A constant roll complicates that. “point in this direction and fire the engines” becomes a pain because, say you’re constantly rolling, and you need to change the direction your long axis points. What thrusters do you fire in what combination to steer the ship? Or do you stop the roll, maneuver/use your telescope/dock/whatever, then start rolling again? So now you’ve got to deal with gravity starting and stopping variously throughout the journey. Or, do you design the ship to have sections that do roll and sections that don’t? First, look up “gyroscopic precession” on Wikipedia. Second, wiring, plumbing etc. is a pain in the ass to handle via slip ring, let alone crew access. Third, that adds weight, which…I should probably stop saying that, rocket scientists aren’t cheap to train and that’s nine we’ve killed just in this list.
In conclusion, look what you made me do.
Could the same thing be said about the Apollo program in the 60’s?
Huh, sure enough. Isn’t that amazing.
That’s not what “lame duck” means.
A lame duck is a politician who is currently in office but is not eligible for re-election due to term limits. A second-term president is the classic example. Being in power and yet guaranteed to soon not be alters the power dynamic and priorities of said politician.
Donald Trump is a lame duck; in his second of two terms.
Pilot here. I’m afraid of running rotors and propellers because they can fucking mince you. I worked on Rotax 912-powered aircraft for awhile, they have twin carburetors that have to be balanced, ie the throttle valves have to open the same amount or one side of the engine is trying to run harder than the other. This has to be done with the engine running. If I had to get from one side of the engine compartment to the other, I’d walk around the tail.
Because that kit would cost around what a new Civic would cost, and you’re going to get a 16 year old car made worse.
EV components don’t really swap into the spots that ICE components do. An engine is relatively large, a motor is relatively small. A gas tank is relatively small, a battery is relatively large. Most ICEs designed from the ground up use a “skateboard”-like chassis with the battery taking up basically all the volume below the floor. The motor can be tucked away somewhere, and then the body built on top. You don’t need the volume in the nose for the engine so you get a frunk. a 15 year old ICE car didn’t portion out the room for the batteries, so you’ve got some of the area under the trunk occupied by the gas tank. That’s about the volume that the batteries in a golf cart take up.
Anyone who’s capable of designing and manufacturing that kit might as well go into production of new cars.
Saturation divers. Something I didn’t realize, they haul the pressure vessel to the surface at the end of every shift, they don’t live at the bottom, but they’re under pressure.
The closest to that I can think of is the Tesla Roadster. Which IIRC was basically an electric Lotus Elise, rather than a Mazda Miata. I wonder how popular electric Miatas would actually be, without a manual transmission.
The most “normal car that happens to be electric” I can think of is the Slate. With the exception of the powertrain and complete lack of a radio, the controls and mechanisms look like they’re from 20 years ago. The more I look at it though the more I think that car is DOA.
I think there’s also a problem with the kinds of EVs everyone tried to sell.
Tesla has seen legitimate success in making EVs a desirable luxury item. The Prius became something of a fashion statement among kale chip eating Californians in the 2000s because of its alleged economy, but it was still an economy car. It wasn’t that nice or luxurious. Tesla made cars people wanted to drive and be seen driving, with an all-electric powertrain.
Pretty much everyone tried to copy that business model, making excessively fast luxury sport sedanover blobs with price tags that make car shoppers start muttering the word “depreciation.”
Meanwhile, EVs tend to be the breeding ground for shit features everybody hates, like touch screen HVAC controls. Nobody wants to make a normal car that happens to be electric, which is what a lot of the buying public wants, but can’t find.
I ripped my DVD collection a couple years ago, and I watched that change over time happen.
The earlier DVDs in my collection came in bespoke packaging designed specifically for the film, they had properly interactive menus complete with easter eggs, commentary tracks, alternate angles, remember when DVD player remotes had an “Angle” button? DVD was a prestige format, it was actually as cool as LaserDisc was supposed to be.
There was the early mass market phase when older movies, or lower budget current releases were put out on double sided discs that had widescreen on one side and “fullscreen” 4:3 on the other, in those half plastic half cardboard cases, remember those? Higher end stuff would be released in what I think of as the standard plastic DVD case. How much plastic was wasted selling them in packaging other than CD jewel cases?
Later on, you got the cases that had the recycling logo cut out of them, the discs got cheaper, features started disappearing, because it was now the budget option. “It’s just on DVD.” DVDs were cheap to make, everybody had a player for them, Blu-Ray now had the prestige releases. The Direct To Bargain Bin releases weren’t exactly the high point of the format but there’s still fun to be had there.
DVD still staggers on, they’re not dead the way VHS is, but it didn’t make it as long. DVDs could do things VHS couldn’t, like TV shows. The advent of binge watching happened on DVD; complete TV series on VHS wasn’t feasible but it works great on DVD. On the other hand, because VHS was the only widely adopted vdieo format for most of its run, you can find weird stuff on VHS that never got pressed onto DVD.
I could argue that VHS was a superior format to both Beta and Laserdisc because it offered a better blend of features.
Laserdisc offered cinemaphile farkles like perfect pause and frame by frame, additional audio tracks etc. but a movie required at least three sides of a disc, and thus two discs with at least two changes. Laserdisc was read-only and thus useless for timeshifting and camcorders. The tape-based formats were slightly worse in quality but could hold an entire movie in one go.
VHS was superior for timeshift and camcorder use than Beta because of the longer run time. There was a mini cassette for miniature VHS camcorders which could be played back on a standard deck with an adapter, Beta never got there AFAIK and insetad Sony went to Hi 8, which never really took off as a home video format the way it frankly should have. VHS was better than Beta at movie distribution because a longer film could fit on an SP VHS cassette, often with room to spare for some commercials at the beginning which helped subsidize the cost.
VHS was at least capable of everything.
DVD didn’t fully kill VHS; It unceremoniously killed LaserDisc and shouldered VHS aside a little. Through most of the 2000s VHS was still going strong, DVD-RAM is surprisingly old but wasn’t adopted that widely. Hard drive based DVRs and smart phone based video recording finally did VHS in.
