Still a bit salty Croatia didn't win the Eurovision.

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.

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.

Wouldn't a simple mirror be more efficient?

Not saying that this is ever going to achieve that much, but the record is Mach 8,5 for rocket sled. https://www.af.mil/News/Article-Display/Article/139307/test-sets-world-land-speed-record/

0,6M I presume is 0,6 Mach, but I'd expect m/s to be the expected unit, which gives us 24,75, so we're at least in the ballpark. Also, he just might have borked the math.

Ahh... the dreaded seven engine approach.

Air breathing engines have vastly superior ISP than rocket engines, so why not use some of that? Turbofan/jet to get up to speed, then ram/scramjet to punch upwards out of the atmo, then your vacuum engine.

To be fair, tape is still number one choice for data archiving. That being said, archiving != usage. That tape is being constantly used. It is amazing that it didn't fall apart from purely mechanical manipulation.

Are the accuracy and precision in stationary situation good enough to consistently hit the target? Can you consider the time of flight negligible? If the projectile takes a fraction of a second to cover the distance and you robot is not moving all that quickly, just ignore the movement, point the shooter in the general direction of your target, spray and pray. Or are you lobbing your projectiles in high and slow arcs?

Just do whatever this book tells you not to. https://www.amazon.com/Avoid-Huge-Ships-John-Trimmer/dp/0870334336

Given the ability, you would opt to squirt high speed jets of hypergolics at your face rather than carry a lighter in your pocket?
