How do you slow down from 2% c and not overshoot your destination?
-
I'd rather see scientists in such positions.

Tail probably helps, but it's not necessary, according to more cats being thrown, this time in the vomit comet.

White total angular momentum can't be changed, it is entirely possible to arbitrarily change orientation. Here's a video demonstration. No rotation at the beginning, spin up then spin down and finally no rotation in a completely opposite orientation.
-
Expectation maybe not, but certainly hope.
The ladies said that the landing angle was changed from the flight 4 to try and make it gentler and that they were hoping to recover as much data as possible from cameras and heat shield. After explosion they said they would not be collecting any more data.

Landed, but RUD.
In any case, Superheavy catch from a different angle shows there was actually quite a bit of clearance between the engines and the tower. This is about the moment it comes closest.
-
Going back to an earlier discussion, the guy just said they are aiming for "tens of meters" accuracy for landing.
-
Starship deorbit should be starting in a few minutes.
-
For a moment it looked like the engines were going to hit the tower sideways, but holy crap that was smooth.
Incredible. 300 tons of flaming steel coming in supersonic, and they catch it mid air.

Not science, but bad stuff in fiction anyway.
In A Quiet Place: Day One (2024), just like the previous two movies (but it's more pronounced in this one), the aliens hunt by sound and are drawn by even the smallest of sounds humans make, yet they completely ignoring all the racket made by their fellow aliens.
Also, this is a still from the same movie. It is one of two almost still frames in the middle of the movie, placed there just to set the atmosphere It lasts for about five seconds and absolutely nothing happens in this shot. It has nothing to do with the plot, it was completely unnecessary. Chess has nothing to do with the movie. It could have been cut out of the movie and absolutely no one would miss it, yet somebody decided this abomination was needed. What is going on here? It a mix of at least four different chess sets, white pieces come in two distinctly different colors, black pawns are not all the same size, queens come from a smaller set, kings and queens are on wrong squares, black bishop is hanging two different ways, black rook is hanging and what's with all that debris on the board? It would have been abandoned for only a few hours, maybe a day (it's not entirely clear since the main character loses conscience at one point) but certainly nowhere near long enough to account for this amount of leaves / flowers. Is it really so hard to find a chess set and look up a realistic position?

Maggie Smith died, age 89.
You may know her as Professor Minerva McGonagall from Harry Potter movies, or Countess of Grantham in Downton Abbey, but her career spans a lifetime.

These guys want to put mirrors in sun-synchronous orbit to shine some extra light at dawn and dusk so solar farms can generate electricity for about two hours more per day. The proposal is a constellation of 60-ish sats with 10 m mirrors, and they count on 175 000 $ revenue per sat per year, considering the spot of light would be about 5 km wide.
They fail to realize that a 10 m mirror can reflect a maximum of about 100 kW, which when spread over a 5 km wide circle gives about 5 milliwatt per square meter, not the usual 1 kW per square meter we get from direct sunlight on a clear summer day.
I can not accept that they missed this fundamental calculation, and since they are fundraising. I call this an outright scam. They can't be this mistaken, it has to be deliberate fraud.

maybe dont prioritize inclusion over merit where human lives are at stake. can you imagine a forest gump apollo 13 crossover? thats what i figure boeing is like right now. il leave the hypothetical movie quotes to somone more funny than i.
Boeing: I've been in orbit for 2 months and 20 days.
Everybody: Quiet, quiet! He's gonna say something!
Boeing: I'm pretty tired... I think I'll go home now.

Boeing grounds its 777x test fleet after finding a severed thrust link (part of the engine mount) following a 5 hour test flight. Inspection of the other two test aircrafts finds cracks in both aircraft. There are two such links for each engine (for redundancy). It's not clear if cracks appear on both links.
According to https://aviationweek.com/air-transport/aircraft-propulsion/boeing-halts-777-9-certification-tests-engine-mount-checks it's a Boeing designed part, not General Electric.

Now my magnetic on orbit attitude mechanism invention has promise.
Magnetorquers are an off the shelf part for cubesats, and even available for much bigger birds.
Unfortunately, the work only around bodies with decent magnetic field.

The only way a totally objective being could exist is if they were all knowing.
I'd imagine that omniscience would be very challenging to write. An omniscient being or culture would encounter no challenges, no surprises, no twists, nothing new to discover or experience. How do you write a story with such a culture without boring your reader to tears?

When I was buying my first ebook readed back in 2010 I made a conscious decision to avoid Kindle.
Last year when I was buying my most recent one, I made the same decision.
My reasoning? Well I figured I wouldn't have control over anything I put on Kindle, taking into account that Amazon demonstrated the ability and willingness to remotely deleted peoples ebooks. To make things worse in the most ironic way possible, it the deleted book was Orwell's 1984.

Something like antimatter?
Also, hydrogen is about then times more energy dense than uranium.

"Yeah, it's time for all this to go."
I moved thirteen years ago and yesterday I threw out some stuff that was still in the moving boxes, unopened all this time.

I introduced a friend to Factorio. At first he was hesitant, but I managed to convince him to give it a go. So I set up a multiplayer game to give him a crash course and we start with "See that big rock over there? Go punch it some. Got some rocks and coal? Cool. We'll need some more. See this blue stuff? That iron. Hold your mouse button on it until you collect some. Got some? Yeah, me too. Let's not do much more of that and make a machine do it for us. Open the inventory and put this thing here. That's a mine. Put some coal in the little box and see... it's doing its thing. Place another one on that black patch, we'll need coal."
So, he's fumbling with that while I collect a bit more of the resources and start placing about three or four more mines on the iron patch when he asks me why am I placing so many iron mines when we already have like two.
Dude now has like 3000 hours in the game.

The worst example of the countdown I've seen must be in the Absolute Zero movie (both name and rating). It's counting down to Earth's magnetic pole flip, which will lead to global temperatures plummeting to, as the name would imply, 0 K.

the nitrogen cycle is necessary for life as we know it
You’d probably want lower concentrations of CO2 as well, because high CO2 negatively affects the uptake of Nitrogen and other minerals
I would presume, if not IRL, certainly if Sci Fi, evolution would have taken care of that. Whatever lifeform evolved in the environment would be well equipped to deal with that environment.

Come on, give that imagination some wings. I'm sure you could think of at least another 5 reasons to dissasemble it that have absolutely nothing to do with reliability of Raptors.
Your needle is so stuck in that groove that it will cut that vinyl all the way through.
