I'm gonna be the annoying guy who points out the obvious thats being repeated again and again for the last 50 years...
For transport, trains! Trains of different sizes, shapes and designs, solve most of the transport issues. The fact that western countries are behind on this doesnt mean it's too late to start.
For heat, better insulation and heat pumps do wonders!
For feedstock maybe feeding animals is simply bot the way we should move forward.
And I say all this as a person who drives a gas car 70 miles every day, lives in an old house with bad insulation and eat meat several times a week
Not only that, but there are quite a few scientifically sound concepts that escape the tyranny of the rocket equation. Pre-seeded trajectories, particle beam propulsion, sails etc. Breaking the wall of light might not be possible but beating the current rockets by orders of magnitudes is enough for interstellar travel. And that is only an engineering problem.
My personal favorite these days is innumerable 'smart' pellets, bacteria sized, steering themselves using albedo-changing surfaces toward the ship's magnetic sail to transfer their momentum, allowing for constant acceleration.
Also my recommendation:
-Make the card vertical instead of horizontal (phones are held vertically)
-Add a +/- bottom on each end of the slider for fine tuning the ppi by 0.1 increment or lower,
-Allow to manually change the value in the field
A few years ago a popular idea was that our universe existed as an hologram on the surface of a black hole.
Recently I saw also a theory that black hole might not, in fact, exist as we thought, and may be instead something called 'gravastars', where large stars do not collapse in an infinite point but instead the mass reaches a maximum density and hardness and become sorts of empty bubbles.
Now this. It's not exactly a new idea, I remember reading about black hole cosmology 10 years ago.
Sooo... My uneducated, pop-sci fueled imagination now sees the universe as a mathematical function of a fractal looking like a shell with patterns on it, and those patterns interact or 'fold' in a way where the patterns themselves can be thought of as shells with patterns on them, and each shell creates something that, from the inside, looks like a new dimension of space or time, and what we think of as black holes are the next fold. Does that make sense?
There's an interesting implication to this. We assume that evolution happens when random mutations (similar to random bit flips, removal or injection?) occur and when the random result has an advantage, the mutation tends to remain in the gene pool.
Yet at the same time the result of this random code is extremely compressed, to the point we compare it to procedural generative code.
Not sure what we can do with this but it certainly seems like we can once again get inspired by nature on this one.
I think the parent comment exposes the obvious flaw of using plasma to drill:
Drilling with diamond bits uses fluid, which is uncompressible. Drilling with plasma uses gas, which is compressible. No matter how thick the obsidian layer get, there is a critical pressure differential between outside and inside and it will crack and collapse.
You could probably use significantly less coolant if you're using heat pipes. The coolant is mainly gaseous and only a small mass remains liquid during the cycle
I started listening to audiobooks (not this one) about 5 years ago, after a job transfer that meant driving 2 hours a day, in slow traffic, with little attention needed (due to a tunnel repair that will likely take decades).
Keep in mind that I was some time ago an avid reader, capable of devouring an entire book in a single night. But for a decade or so I found myself feeling eye fatigue while reading and I just stopped reading books altogether.
Driving and listening to audiobooks just works for my brain, in a way that radio's unoriginal music or taking hosts or podcast do not. Without listening to audiobooks, driving is boring, frustrating, tiring. When I listen to an audiobook, I become attentive, focused, wide awake, and most importantly it transforms a bad part of my day into a part of the day I genuinely enjoy.
As long as the book is engaging and narrator is good.
Now my first exploration into the format was 'The Expanse' series, then 'The Siege' trilogy, and maybe a dozen more, including non-fiction like 'Longitude'.
English is not my first language and I found that while original french audiobooks can be great (I really enjoyed 'La Bête' trilogy by David Goudreault) I found that translation are generally very bad for audiobooks.
Eventually I had the pleasure of listening The Bobiverse Series, engaged on the subreddit and saw a recommendation for DCC. Then another and another.
The premise seemed so ridiculous. The litrpg 'genre' appeared horrifyingly bad and off-putting. And yet I kept seeing it over and over again, so I tried the first book.
Now it won't be a surprise to any seasoned reader that it's not the genre, the premise or the author that makes a good book. It's a lot more personal, in the genuine connection with the soul the story can generate, through humor and horror, hope and fear, love and hate, curiosity and ehat I like to call 'brain tickling'. And, for me at least, Matt has done this at a level I've never felt before, with a guy in boxers and a talking cat, no less.
It feels less like a word prediction algorithm and more like a world model compression algorithm. Maybe we tried to create one and accidentaly created the other?
Not sure what functionality is not covered by current cables. Both my laptop and phone, which are several years old, use the usb-C connector for power, data, video, audio, and combined with a hub can connect to any usb peripheral out there.
Sure, the weird triple-split usb-c connector that came with my son's cheap walkie-talkies from Amazon doesn't do all that. But I don't expect it to, and it will at least charge my phone if I plug it, and that's the primary usage I want for this cable.
I learned to drive with a manual transmission so I'd feel comfortable driving any car in Europe, where manual transmissions are far more common. The transition was stressful but after a few hours it became easier and after a few days, it became second nature—just as easy as driving an automatic.
Today, my own car has a manual transmission, which I prefer for the added control. It lets me use different levels of engine braking on downhill stretches (very useful depending on where you live) and manage my speed more precisely in heavy traffic.
I like to refer to this kind of article when a kid has trouble understanding why they need to provide sources in their homework. Sometimes it's difficult for them to understand that this kind of assertation, that people use constantly in a conversational context, just sounds like a poorly formulated opinion when it's written down.
I'm curious about the Aldrin Cycler analysis. Isn't the whole point of the "castle" to house travelers and life support system in a larger habitable space during the long travel, independently of the cargo required for mars that's carried on a different, cheaper trajectory?
I don't think this result reflects all antibiotic treatments:
"RESULTS Oral antibiotic treatment disrupts the colonic mucus barrier"
Intraveinous administration may or may not cause the same effect, or a similar effect. Maybe oral antibiotics is generally a bad idea because it disrupts the microbiome, but in other forms it's generally fine.
