00:04Welcome aboard! Your first job in this station is to guard against meteor attacks.
00:09Those happen fairly often here, so we have some rotating platforms to defend against.
00:14Now you may ask, why not just have force fields?
00:18The answer is, we don't have the budget and we have to use moving platforms instead.
00:23That's life for you.
00:26Anyhow, to describe how it goes.
00:28First we get a report of meteors that are flying towards the station.
00:32We also get information on the available platforms.
00:35The task is to set the initial rotation, aka theta, for each platform.
00:41So that meteors crash into platforms and not into the space station.
00:45Before you can operate the platforms you ought to know how the dashboard works.
00:49Buttons before everything else.
00:51You first want to start with the forecast view.
00:54It contains information about the upcoming meteors, as well as platforms you will need to configure.
01:00You can't defend against what you don't know.
01:03You know.
01:04Moving on, there's config view which opens up the configuration terminal which lets you change the initial rotation.
01:11Now you might ask, how to know which angles to use.
01:14First and foremost, brute force is not the key.
01:17I once tried it.
01:19Had to be responsible for repairing that hole.
01:21I'd much rather watch paint dry.
01:23So it was not worth it.
01:26For that you use a formula and it's such.
01:28This formula required some trigonometric magic and I've added the proof which I've written back in the days when we
01:35first got the rotating platforms.
01:37I'll be honest, while I kind of understand how to get there, I'm not certain I would reach this myself.
01:43Even if I'd be held at gunpoint.
01:45So don't worry if you don't get how.
01:47Just know that it works.
01:49Also, you don't even have to know it because we have Kalydex, the machinery that does the calculations for us.
01:55Just press the calculate button.
01:57And you get the angles and all that's left is to just take them and insert them in the configuration
02:02terminal.
02:03Actually, it's not that easy.
02:05Usually there are two platforms and three meteors.
02:08So that means that at least one platform would need to take care of at least two meteors.
02:13Either one platform takes down three meteors or one platform takes down two and the other one takes down another
02:19meteor.
02:20Keep that in mind while picking the right angles.
02:23When you have done your configuration, it's time to go to the confirm view and finalize your configuration.
02:29Remember, you mess up, you clean up.
02:34Although it would probably be better to show a more concrete example and the thought process behind the job.
02:40Okay, so first of all I take a look at the current situation.
02:44Meteors seem to have quite different velocities and so do platforms.
02:48There's not much to be done here since I'm going to rely on calculated values anyways.
02:53Since I had pressed the calculation button before, the results are already here.
02:58By carefully examining the results I noticed that P2 can deflect both M1 and M3 if we configure it to
03:055.5099.
03:07So that's what I'll do now.
03:09Off to config.
03:10And there we go.
03:11Alright, now we know that M1 and M3 are covered and thus P1 has to handle M2.
03:17I can take any value from M2 P1.
03:200.7023 looks nice.
03:23So I'll take that.
03:250.7023.
03:27Alright, so the configuration is done.
03:29As you can see, the platforms have moved accordingly.
03:33It's time to confirm and see them go.
03:43As easy as that.
03:44Hope you got this until later.
03:46lead me back
04:16finally或許
04:28To be continued...
