Guard Dog Posted March 14, 2018 Posted March 14, 2018 Think they will work on orbital insertion before space infantry weapons No kidding. There have been 19 attempted landings on Mars, 9 have failed. That's not exactly an inspiring success rate. "While it is true you learn with age, the down side is what you often learn is what a damn fool you were before" Thomas Sowell
Zoraptor Posted March 14, 2018 Posted March 14, 2018 Well, they've developed guns that can fire bullets (and bullets that can be fired) underwater which is effectively the same as firing a gun in an oxygen free environment. In fact, I'm pretty sure both the US and Russia (and others) have developed guns and bullets that can be fired in space (recoil in microgravity nonwithstanding) if someone had to. Any modern gun can fire in space, modern cartridges are sealed so don't interact with the atmosphere anyway; that has a major military advantage as sealed cartridges stay dry and don't age anywhere near as quickly as they used to from oxygen exposure. The side effect is that they will also fire without an atmosphere. It works because the propellants don't require oxygen since they either have an oxidiser added or intrinsically degrade upon triggering. eg, for nitroguanasine since wikipedia has the equation handy: H4N4CO2 (s) -> 2 H2O (g) + 2 N2 (g) + C (s) No oxygen required, just a percussion (or whatever, generally electricity or heat would work as well but guns use percussion, so...). Guns firing underwater are a different problem to do with water's density and incompressibility, a gun may fire underwater due to having sealed cartridges- if it doesn't it's due to water getting into the percussion mechanism and slowing it too much or similar- but you won't get a happy result from it, a blown barrel or breach, whichever is weaker, I'd suspect. If you want a gun to fire underwater you need a way to clear the water from the barrel first and it cannot work over much distance anyway since it will lose its impetus too quickly. Hence underwater 'rockets', torpedoes, being favoured. Consider torpedo warheads, mines or depth charges as well, none require oxygen and they are, in essence, just giant cartridges with no bullet.
Guard Dog Posted March 14, 2018 Posted March 14, 2018 I can tell you for a fact bullet crimps are not air tight. they are not even water tight. Maybe 95-98% but not 100%. Speaking from experience here. If they are submerged for more than a few minutes they are ruined. The US military buys all of it's small arms munitions from a company called Alliant. The stuff they make MAY be water tight at 1 atm. The stuff I buy from Eagle Arms & Winchester surely is not.

smjjames Posted March 14, 2018 Posted March 14, 2018 Given his apparent stance on violent videogames (or at least the gratuitously violent), he probably wouldn't even let his kid play that game, which is ironic because gunz and all that.

The stuff they make MAY be water tight at 1 atm. The stuff I buy from Eagle Arms & Winchester surely is not. The parallel would be to something like Pasteur's swan neck flask- it's a sealed system (remains sterile, minimal atmospheric exchange) but it isn't fully airtight. IIRC they make military ammo watertight using a plasticised lining/ sealant, that's expensive and overkill for civilian rounds where incidental immersion just means you throw the ammo away and maybe don't bag any deer or rabbits that day. Firing a gun underwater was more of a digression about there being fundamental problems with it apart from ammo getting wet, and it's at least passably interesting (to me, at least) as a reason for why you have torpedoes rather than underwater guns and why torpedoes have a severe speed limit unless you're very imaginative (motor at front sheathing the torpedo in air). Could have just left it at mines/ torpedo warheads/ depth charges not needing oxygen, I guess.

Guard Dog Posted March 14, 2018 Posted March 14, 2018 Now I'm curious if you could use a gun to fire a bullet into orbit on Mars. You can theoretically here, of course, but it's very much in theory with our atmosphere/ gravity/ planetary radius. I don't think so. The muzzle velocity of a 5.56 mm round is a around 3300 fps give or take. Escape velocity on earth is a little over 11 km/s. So if Mars has 40% of the G as here 5 km/s would be a good estimate of Mars's escape V. 3300 FPS is 1000 m/s, so 1 km/s (ball park, I'm just doing this in my head not a calculator so don't bet on any of this). So if you were on Mars and fired a bullet in the air I suggest you get out of the way. It's coming back down.

smjjames Posted March 14, 2018 Posted March 14, 2018 Just once I'd like to see a politician accept defeat with grace. Not holding my breath. To be fair, they're both within reason to call a recount. I too thought there'd be an automatic recount as it's within range of one.
Guard Dog Posted March 14, 2018 Posted March 14, 2018 Actually there are enough absentee ballots out to turn the election, if they go 90% one way. Not likely but still something for the Republican to hope on. "While it is true you learn with age, the down side is what you often learn is what a damn fool you were before" Thomas Sowell
smjjames Posted March 14, 2018 Posted March 14, 2018 Even if Saccone wins, he'll have to run again in November and because the districts will be redrawn, it won't exist in it's current shape anymore.
Bartimaeus Posted March 14, 2018 Posted March 14, 2018 It was my understanding that that was true last night, but the bigger of the two counties that had outstanding absentee ballots have now been counted, and there are only around two hundred remaining absentee ballots remaining in the other outstanding county, and even if they were 100% for the Republican, it wouldn't be enough.

Somewhat relevant to this, I can't help but think that the US has learnt completely the wrong lesson from Putin's success. Trump- and a decent proportion of the US in general- confuses respect and fear and wanted a 'decisive' leader to bring back fear rather than respect. Part of being 'strong' in that sense is not having dissent in the ranks, hence Trump wanting yes men in every position (plus his fragile as bone china ego). But the fundamental problem remains the same as with GWB's big projects, it's not actually a lack of decisiveness but a lack of acceptance of reality that is the fundamental problem, and having only yes men exacerbates that rather than ameliorates it. Putin has a lot of fear and respect (and for Russia the fear aspect is an enhancement, as they have very little soft power at all) because his decisions, while autocratic, are also realistic and so have a far better success rate. US decisions are far too often based on what they want to be true, rather than what is true. That leads to massive erosions of trust when things don't work out: if you say that Iraq will be stable for 15 consecutive years and it isn't or that the Taleban is losing badly for 17 (!) consecutive years and they don't then you're only ruining your credibility. Given that Trump's knowledge is not the greatest a 'gut feeling' based US policies with no internal dissent looks terrible, even if the US system overall moderates things a bit. 2
smjjames Posted March 14, 2018 Posted March 14, 2018 I wonder how many countries went through a period like this only to crash and burn or just hit rock bottom and manage to recover? I don't think the US tried to learn any sort of lession from Putin's success, this is part of a pattern that has been slowly growing over decades
