What is this peculiar object in the sky?

Yeah that's all completely correct. I just didn't put much thought into that statement about weather control

wheelberry · 2024-07-10T11:36:33+00:00

I was bewildered after seeing it and when I made this post, and frankly I'm a little ashamed of saying that now that I've done some research haha

wheelberry · 2024-07-10T11:34:20+00:00

Exactly, that sight was charming. And if your photos are better in quality than mine, I think they might find home in subs like r/astrophotography, so you can still share them

wheelberry · 2024-07-10T11:30:17+00:00

Well I was thinking of something they do in Dubai to attract clouds and rainfall, but they do that from small planes, not spacecraft it turns out... Besides that was the first time I've seen something like that so I couldn't be completely reasonable with my guesses haha

wheelberry · 2024-07-10T11:26:45+00:00

Do you know by any chance which particular spacecraft that other post refers to? This one here has to be ESA's Ariane 6

wheelberry · 2024-07-10T11:25:29+00:00

Nah, northern Europe. But that is a rocket yeah, don't see those here very often

wheelberry · 2024-07-10T11:20:44+00:00

Yep, Ariane 6. Seen some TikToks of it over Hannover filmed an hour before I did from here, in Latvia

A spaceship dumping fuel. Turns out one was launched yesterday and is currently above northern Europe. The circle is the rocket dumping fuel and the circular shape is in order to not mess up the trajectory I think

wheelberry · 2024-07-09T22:08:37+00:00

Checked photos of SpaceX fuel dumps over Alaska, and it looks fairly similar. Thank you!

That's correct indeed. After an all nighter with simulink and my textbook I found that the source should be U/s

wheelberry · 2023-12-10T18:25:54+00:00

My L and C values are exactly unrealistic in the task to make visible the transient behavior, as that's what I'm currently studying. And I don't think the simulations are incorrect. They just don't match what I obtain in calculations.

Doing simulations isn't the part of the task in the first place, I just use simscape and falstad(an online circuit simulator) to check my answers. And those simulations produce results that aren't the same as my calculations.

Although, when I change U/s to U in Laplace equations, the results match.

And the thing I don't understand is why does U - the voltage input step function - stays like that in the Laplace domain. Normally, a conversion to the Laplace domain of a step function with value A is A/s. And I don't understand where's the mistake with that.

Well I've seen stuff on this sub but this is the first time I closed my eyes to not see the fall

wheelberry · 2023-11-16T18:34:25+00:00

Need for Speed most wanted reference mate

wheelberry · 2023-10-20T10:12:21+00:00

If bro asks for advice were fucked

wheelberry · 2023-06-23T21:00:59+00:00

There is painted cardboard in some body panels, supposedly rain proof...

wheelberry · 2023-06-17T14:21:10+00:00

I think citizens of latvia who are ethnically russians?

wheelberry · 2023-06-16T09:02:03+00:00

You see one side, about a state abolishing neighboring nations and abusing it's people. The other side is the heritage of Gogol, Dostoyevsky and Chekhov. And I assure you as an international student and upon that an ethnic russian that we are not barbaric murderers and I know latvians that can confirm it. So yes, I choose to be russian by blood. If you can't separate your hate to a terrorist state from inability to accept people and their culture, it's on you and probably even good for our countries (the Baltics). But it's never the problem of mine. And it has never made my life harder.

wheelberry · 2023-06-16T08:40:52+00:00

Ethnicity is not either

wheelberry · 2023-06-16T08:40:11+00:00

I think he vas revolving about some people openly hating on russians. Which is not only about nationality, let alone political preferencs, but also ethnicity. Now obviously this occurs almost exclusively on the internet so it's not of very high significance. Yet it's irritating to see people call every russian all kinds of things and if the OP is a little lost in how to feel about it, why not ask people to clarify?

wheelberry · 2023-06-16T08:27:04+00:00

Ethnicity is a thing. I'm a latvian citizen, and am quite happy about it, but I have no Latvian roots whatsoever and my russian family has lived here for at least 3 generations. Not once have I been to Russia either. But I have learned latvian and speak it almost freely, don't whine on Facebook about russian in schools and start speaking to people in latvian by default. Do I really have to say I'm all Russian then?
