Lunchtime

@not__vee I don't know man ... There are some countries in Europe right now where drafting lots of white men and giving them training and a weapon could be a political suicide by the government.

The funny thing is that modern people believe "You'd have a choice". The entire military aparatus is designed by EXPECTING people do not want to fight or that they will rebel. The mass psychology tricks employed are made to break, and indoctrinate young men into killers. For a paralel example the English used to even have the concept of "Press Gangs" back in the day specificaly made to force people into service.

@SharklettVT You told someone to get a job? You don't even feel self conscious about it, do you?

i told somebody to shut up and get a job in an assetto corsa server. in responce they claimed to be a business woman (CEO) while exploding in the chat at me. the person has 36 hours in assetto corsa- what is wrong with some people they are deranged

@andy_not_today @OregonTerritory @Object_Zero_ It is not used in thermite reactions as far as I know, the big downside, remember? I think there are other downsides beside that too. In fact I don't think thermite reactions are used at all really except very few specialized cases like railway welding and those all use FeO + Al

@Rolnicek @OregonTerritory @Object_Zero_ Is it used in other thermite reactions?

The Kroll Process… (again) Titanium (Ti) Humans could use a lot more titanium if we had it… we actually DO have it. The ore is super abundant, it’s just humans are bad at Titanium processing, super bad at it. Ti has two great properties first it’s fully corrosion resistant and secondly it has high strength to density ratio. It’s so corrosion resistant, it’s the preferred material for surgical implants. It’s an extremely biocompatible material to the point where your bones can be replaced with titanium bones (surprised we don’t see more body modification like this). On strength to density, titanium has the highest strength to density of any metallic element. Pure titanium is as strong as steel but is only 57% the weight. The only reason we don’t have a lot more titanium is the economics. Titanium ore costs about 20% the cost of aluminium ore, but titanium requires vastly more energy than aluminium to process. So much so that a titanium ingot is about 5x the price of an aluminium ingot. Titanium is also a lot harder to machine and join, so finishing titanium parts can be 100x the price of finished aluminium parts, even though the titanium ore is much cheaper than aluminium. So even though titanium is a technically superior material to aluminium and steel, we’re not very good at it, so it remains frustratingly expensive. The majority of our manufacturing processes were developed for steel. Titanium is still locked behind the Kroll process which converts titanium ore into sponge, the process is 10x more energy intensive than processing aluminium ore and 50x more energy intensive than processing iron ore. It’s batch based, energy intensive and dirty. If someone could only figure out something better than the Kroll process, we would move closer to the biocompatible super structural material that we need. Steel is made from iron and iron is very reactive with oxygen, it’s why our blood is iron, but we don’t want reactive structures. We don’t want bridges and railways that rust. We really want chemically inert structures. We really want titanium structures. There are still many cases whee steel is always best, and my favourite material is steel because that’s what we have mastered. Steel is currently our baseline economic material, but we should be working much harder to find an economic way to move to structures dominated by titanium alloys. Titanium buildings could last for 1,000 years without corroding or falling into disrepair. We need to find a way to get past the expensive Kroll process. The Kroll process is holding us back. Someone needs to find a better way.

@andy_not_today @OregonTerritory @Object_Zero_ Sodium is extremely reactive which makes it great for thermite because it's very eager to pull off oxygen from whatever metal oxide you give it. The big downside though is ... Sodium is extremely reactive.

@Rolnicek @OregonTerritory @Object_Zero_ This is the first time I’ve heard about sodium thermite. Interesting idea.

@andy_not_today @OregonTerritory @Object_Zero_ That's the gist of it. When you do it in your backyard, you're getting massive impurities and incomplete reaction, Aluminium and TiO mixed in with the final product (I believe). That's another reason why I'd try Sodium for the industrial thermite process.

@OregonTerritory @Rolnicek @Object_Zero_ If I remember well, the thermite path is used by some amateurs to make titanium for pyrotechnic purposes. I suppose the titanium made this way is too impure to be used for other applications.

@planefag They can't put him to this work. As a sex offender he won't be allowed to do any outside work where he might come into contact with civillians. Only indoor labor for sex offenders.

BRUH

@OregonTerritory @Object_Zero_ Same way it makes any other metal. You get Titanium Oxide and a pure metal that likes oxygen even more than Titanium (usually it's aluminium but I'd use Sodium) and then you kick off the reaction with a lot of initial energy and then the metals exothermically exchange oxygen.

@Rolnicek @Object_Zero_ How would a thermite reaction make titanium?

@rosseatsrocks Apparently the answer to that is "maybe in the future": x.com/TheDrMAWZ/stat…

does anyone know how to make this happen. has anyone looked into this

@peterrhague @A_J_Higgins Well peer review may be very recent, only getting introduced at about the same time that scientific progress was slashed to instead produce mostly junk papers (surely for unrelated reasons) but ... where was I going with this?

@A_J_Higgins Is it really though? The foundational work in modern physics was never peer reviewed.

Not wrong…but peer review is still the best system we’ve come up with.

@SalmanGreen Link?

3D Printed OTF Toy.

Man, computer hardware is going to get MUCH faster, isn't it? Only though use of modern AI will programmers be able to undo all of this progress to somehow make games run even worse like they've been doing so far.

@SharklettVT Already? When I buy new shoes it's hell for at least a few weeks before they become close to as comfortable as the old ones.

i finally went to buy new shoes today... my old shoes i've had for 12 years. walking now is effortless, this is great why did i hold off for so long

@digitalbin1 @ToupeeCostanza @found_it_funny On Earth it is feasible (and within reasonable budget) to build a mass driver that shoots you straight into a Mars transfer trajectory. No need to correct that trajectory into orbit since it was never ballistic. At some volume of travel it becomes cheaper than Starship fuel alone

@ToupeeCostanza @Rolnicek @found_it_funny But the thing @Rolnicek said is relevant. Mass drivers would still work (at least longer) since they don't make the rocket heavier. Then it is just structural stresses on the rocket/projectile and the bit of fuel you need to get from a ballistic trajectory into orbit.

@ToupeeCostanza @found_it_funny (fake numbers) let's say 1kg of fuel on Earth can take itself plus 1 gram into orbit so that's 1001 grams. That means 1 ton of fuel can take 1kg of payload into orbit. On a worse planet lets say 1kg of fuel can take 900 grams into orbit. That means not quite even its own weight.

@Rolnicek @found_it_funny i don't understand why it wouldn't be possible for everything to just scale up in size?

@Rod__Mason Yea good luck. You can keep voting them out every time (and you should) but don't expect them to stop doing what they're doing just because you voted them out every time they did it (which was every time)

@Rolnicek I said ‘the government,’ not government. I’m suggesting we vote this government out; I’m not advocating for anarchy, with no government at all in place.

Farmers: please don’t blockade the nation; you’d only be making things even worse for ordinary people. If you must protest, do so against the government directly instead - and vote against them on 7th May.

@Rod__Mason And how is that going to remove government exactly? I've voted a few times already, tried various options. Sadly government still exists.

@Rolnicek You just vote for any party except Labour - and especially the party you think most likely to beat Labour in your location.

Turns out bioterrorism is almost legal. That explains the Citrus Greening Disease that took out all the oranges in Florida and similar attempts. Why not try it if there's no consequence?
