Such a shame Edmonton City Centre was closed and everything had to go to loving Leduc City Centre. I'd always heard jokes about how far it was away and then I went there and... holy gently caress.

From the Wikipedia article about the Dean Drive: quote:In the 1950s Jerry Pournelle, working for an aerospace company, contacted Dean to investigate purchasing the device. Dean refused to demonstrate the device without pre-payment and promise of a Nobel prize. Pournelle's company were unwilling to pay for the right to examine the device and never saw the purported model. 3M sent representatives about the same time, and obtained similar results. Pournelle eventually was convinced that Dean's device never worked.[12] Normal bit of negotiation there, require a Nobel prize.

mllaneza posted:2. Vacuum is not cold. You need extensive radiator arrays to get rid of heat in a vacuum. This is a rare error on Nyrath's part. My understanding was less that it's not "cold" than there isn't much of anything to be cold or warmed up. Meaning you have to straight up radiate out the energy into the void vs the usually much faster and efficient method of dumping that energy into a transitionary material like water or air or so on to let the energy spread out there before entropy takes hold. It was one of the more interesting little points of the Mass Effect games. Your "ammo" is infinite, but you have thermal clips of some sci fi material that sucks up the waste heat/energy of your weapons that needs replacing once it hits capacity. Functionally it's the same thing from gameplay functionality but it's a neat in universe way of covering their asses.

Any gun can shoot forever if you do it at a reasonable rate, but if you need to fire fast and continuously, you can eject the radiator and swap in a new one from a limited supply of spares. Like changing the barrel on a heavy machine gun. It would be lore-accurate and I'm sure it could be balanced for gameplay too.

Meaning you have to straight up radiate out the energy into the void vs the usually much faster and efficient method of dumping that energy into a transitionary material like water or air or so on to let the energy spread out there before entropy takes hold. Space is cold. Space is very cold. If you're in deep space and you don't have any big bright warm lights shining on you the ambient temperature is about 3 kelvin. The requirement for cooling comes from exactly what you state: since you can't remove heat with convection or conduction, the only thing left is to radiate. If you've got something with a light source shining on it, it's going to heat up until it reaches a temperature where it's radiating as much as it's absorbing. If you've got something with an internal heat source (like a person), same thing: it's going to heat up until the power emitted equals the power produced. So unless your system is capable of operating at those temperatures, you need to remove heat from it and shunt that heat over to a system that can.

The best (worst) example of this is that there’s a gun that’s supposed to be a historic relic, but instead of special-casing it to not use disposable heat sinks in ME2, the devs gave it a codex entry that says that it was modified to use disposable heat sinks.

ME2 had so much terrible trash and were really the beginning of the end for bioware. Absolute dumbest gun/physics were this thing though, and I still remember it 14 years later M-920 Cain posted:Normandy's scientists have prototyped a modified version of traditional high-explosive rounds that is applied to a 25-gram slug. When accelerated to 5 km/s, the round is devastating. Though a technically inaccurate label, this prototype weapon is nicknamed the "Nuke Launcher," and its high-explosive matrix generates an archetypical mushroom cloud on impact. 25 grams of high explosive, baby. No concept of why mushroom clouds happen. And best of all, the mach 15 round goes as slow as a softball, you really have to lead your target.

The interplanetary medium is actually quite hot but the density is so low it’s really pretty meaningless. Similarly the “speed of sound” is an important property of space but sound doesn’t propagate in a way we’d be familiar with. In the interstellar medium “warm” is 6000-10000 K but the density is on the order of 0.5/cm3. “Hot” is 106K and “cold” is 50K Along similar lines, did you know that the moon has an atmosphere?

Platystemon posted:The metal bird race I do I know not your JK Rowling references, but I can tell you that you missed a few races: The Grizzly Bear-like dudes, who were contacted but because certain basic social situations trigger extreme violence in them it didn't go anywhere The Geth, the flashlight heads that are a machine sorta group intelligence The Quarians, the people who didn't handle the geth becoming actually intelligent so well The Rachni, the biological insect hive mind intelligence The Space Kraken that built the Reapers, which had been hiding all this time despite having vastly extended knowledge (oh and the ability to almost telepathically control life) The Reapers, the first demonstration that just because something existed like 200 million years doesn't mean it's not gonna be real dumb The Awakened Collectors, who despite being nightmarish biological robots get separated from their hive intelligence EDI and co, who are weaponized hot women, the AI That one remaining Prothean, who as it turns out were insect-like As I played the ME3 multiplayer quite a bit, let me tell you the Drell and Lizard-like, and have a "bonus damage / extra squishy" template. The Batarians are four eyed slug people who's extensive space rome (if space rome had enough technology to gently caress up whole planet biospheres) is entirely mulched by the start of ME3. The ME3 multiplater Batarians were all expats who were fighting because they basically had nothing else to do. The Vorcha were, in essence space rats. They got damage buffs as they killed things quickly and could regenerate health, and got a especially moble set of special moves. The awakened collectors and EDI-esque Hookerbot come from there. The awakened collectors were very power space magicians. The Hookerbots were inverse infiltrators, they got damage bonuses to shotguns and could resurrect themselves. If you want to be angry at mass effect writers, read the "Heechee Trilogy" by Frederick Pohl. Actually if you like scifi, read it anyway, it's kinda great! A lot of Mass Effect's overarching plot was cribbed from there.

I was only listing races who were vaguely acknowledged as people by the Council, not all sentient beings. I thought that Cactus Ghost was talking about the Quarians, but I see now that it was the Asari. They are both represented exclusively by women in catsuits in the first game. Men in catsuits appear in the second game. The JKR thing is that she, too, loves to add things to the books by Twitter decree. https://twitter.com/jk_rowling/status/544946669448867841

YOU NERDS anyway https://www.youtube.com/watch?v=l0e_xZFSSRw&t=232s I came across this, a video that was shot from the cockpit of a Tu-160 Blackjack. The cockpit is slightly odd. So you have your two pilots and your two other crew in normal* positions, then there is a narrow hallway that leads back to the ingress hatch that opens into the forward landing gear bay, and above that, the toilet.  That's not so odd; what is a bit odd is that the pilot's seats move from a ingress-egress position, up to the actual flight position, and I mean they move up, like the cabin isn't on the right level for a sitting pilot to have a proper view out. Also (and this is sort of terrifying) I don't know how the seats move, but they almost crush the video narrator

I wonder if that is a deliberate design choice to protect the crew from nuclear flash? On the British V-bombers every window in the cockpit could be covered by retractable screens, and when flying combat exercises (and in any hypothetical Cold War-gone-Hot scenario) they would be put up shortly after takeoff and lowered just before landing. The vast majority of the mission was flown entirely on instruments with navigation, targetting, weapons release and self-defence being done by radio, radar and inertial navigation. I suspect the Tu-160 is similar - the pilots fly most of the time with the seats in the lower position, better-protected from flash by the fuselage and panels, lifting the seats up for the brief bits of visual and hand flying. I'm pretty sure the Tu-160 also had not only an onboard kitchenette for heating ration packs but seats with pneumatic 'massage' function to reduce crew fatigue on long missions.

More a sceptism of how effective or comfortable the massage function on a Soviet bomber designed in the 1970s with ejector seats that would kill the crew when used with the seat in certain positions (read: a position set for any pilot over about 5' 8") because they were originally designed for fighters would actually be.

But oh the plot holes. the "bomb" on this airliner apparently has an altimeter trigger, but to throw it out they need to depressurise the aircraft. ATC displays look weirdly like the PFD and MFD on a 747, and the Hero Plane was a narrow body with two engines on takeoff but has morphed into a 747 in the aerial combat scenes (yes aerial combat involving a 747). Edit: holy poo poo, they just threw the bomb out of the cargo door in flight and it landed on the mig 29 that was attacking them from 090 (straight ahead, apparently). And now the stewardess has to land the plane..... Edit 2: butter straight on the centre line, cheering, etc. what a ride kalleth fucked around with this message at 20:07 on Feb 1, 2024 |
