The Earth rotates around an axis.. any attempt to make "direct video" means you will get blurry video with stars looking like this: To prevent this, when the object you want to record is in close range (i.e. in parsecs), the "recording device" must rotate/move accordingly with the Earth's rotation. The farther away you want to record an object, the longer you have to collect photons from it.

Finland is a country where homelessness is a one-year problem. After winter, there are no more homeless people. The U.S. is pathological in thousands of areas.. They wanted to demolish buildings built before the 2009 crisis, from which people were evicted due to their inability to pay loans and rent.. Instead, the banks got the money, not the people they evicted.. In fact, the whole world is pathological in thousands of areas.. The only smart solution is to demolish the whole world and build a new one.. V.P.'s Russia on the other hand, sent them into Ukraine in the first lane of battle.. "No man, no problem" - proclaims an old Russian adage.

Are they homeless because they were addicted to drugs? or Are they addicted to drugs because they are homeless? or Are they addicted to drugs because in North America opioids are prescribed for "everything" ? https://www.google.com/search?q=opioids+epidemic+in+america What is the sense of existence of private owned pharmaceutics companies? Unlike the public goodness, their existence, their income relies on how many people are ill (the longer they are ill, chronic deseases, the better for them).. What is the sense of existence of private owned arm industry? Unlike the public goodness, their existence, their income depends on how many people fight and die in wars.. The more causalities, the more wars, the better for them.. or Are they homeless because some white collar decided to push credit on them to get a bonus for it, knowing that they won't be able to pay back.. ?

"No one calls conflicts as they happen".. BTW, Russians (etc.) do not call World War II, World War II, but "The Great Patriotic War".. and according to them it didn't start 1st September 1939, but 22 June 1941. https://en.wikipedia.org/wiki/Great_Patriotic_War_(term) History lessons in each country are completely different.. But you don't have a clue about that..

Why do you think so.. ? We are already in the middle.. No one calls conflicts as they happen.. "The Hundred Years' War" was called in its early days? I already said in another thread what is happening: V.P. is waiting for the current Western democratic leaders terms to end.. To replace them with ready-made sockpuppets, walking among you. If someone is not a complete idiot, knows who are they.. They do not even hide in the darkest corner of the room.. https://www.politico.com/news/2022/02/23/trump-putin-ukraine-invasion-00010923 They openly share their affection for ass-licking.. Just an example. If Anonymous were smart, they would annihilate his all assets, and the all similar to him, minions, instead of all these idiotic actions in Russia..

I meant sociopaths and psychopaths don't care about the casualties of their actions..

@J.C.MacSwellWhat else could they say? Sociopaths and psychopaths don't care about such things..

General advice: have you tried using a debugger? There are even Python online debuggers such as: https://www.onlinegdb.com/online_python_debugger

What is the difference among 90%, 99%, and 100% chocolate?
Sensei replied to kenny1999's topic in Amateur Science
I see that the Lindt no sugar version has a higher price i.e. the sugar is replaced by something else. They are usually more expensive than fructose, glucose or sucrose. -
Why is (x = y) == x is not the same as x == (x = y) ?
Sensei replied to Bunty12's topic in Computer Science
In C# it is the same: using System; class Test { static void Main( string [] args ) { int x = 1; int y = 3; Console.WriteLine("pre x={0} y={1}", x, y ); Console.WriteLine(x == (x = y)); // false Console.WriteLine("post x={0} y={1}", x, y ); x = 1; // reset Console.WriteLine("pre x={0} y={1}", x, y ); Console.WriteLine((x = y) == x); // true Console.WriteLine("post x={0} y={1}", x, y ); } } In languages that allow overloading of operators, you can try to create your own class with overloaded assignment and comparison operators and do logging there. -
Did you see a UFO? No, it was a balloon. Did you see a balloon? No, it was a UFO. A balloon? A UFO? Unsure...

What is the simplest way to set up a Donation Page?
Sensei replied to PeterBushMan's topic in Computer Help
You can use crowdfunding platforms. https://www.google.com/search?q=crowdfunding+platforms Doubtful it will be enough attractive and effective to anybody participate in it. -
..are such programs needed.. ? You thaw the meat and bake or fry it.. and you eat it..

Different planets have different surface areas facing the Sun. You need to calculate the surface area of the planet and use it in calculating what total Watts per planet they get, not just leave it at Watts/m^2. Then multiply these Watts by the albedo of the planet. Do this in different columns in Excel. Include the raw data too, i.e. distance, radius, albedo, area, for readers and your convenience in calculations (use the column as a data source in the equation).
-
See my post - you also need to take into account the radius/diameter of the planet (therefor, the area facing the Sun) and albedo. Read both Wikipedia articles carefully.
-
The Earth's surface receives 1370 W/m^2 per surface area facing the Sun. Some of it is reflected, some is absorbed by the atmosphere, and some is absorbed by the land and sea. Knowing the distance of the Sun from the Earth, the total power generated by the Sun can be calculated. Then you can do similar calculations (check the inverse-square law) for any other space object on your list and find out what Watts/m^2 they receive. https://en.wikipedia.org/wiki/Inverse-square_law https://en.wikipedia.org/wiki/Albedo

You can press "print screen" and attach image instead.

@Saber Did you have trigonometry in school? Use Pythagoras' triangle to find out how curvature changes with distance: What you see here, 6 degrees, would be equivalent of ~ 670 km.

I created flat ground plane with 1km x 1km size. Basically, you can't see the difference. The edge (the blue-gray transition, 1-2 pixels in the image) is 500m from the camera.

I added 100m x 100m x 100m box. Its center is 0.01 degrees away from us. 2*PI*6370000m / 360 / 100 = 1111.8m - 50m = 1061.8 m. Approximately 1km from the camera. Another view, but 0.1 degrees away from us.2*PI*6370000m / 360 / 10 = 11117.7m - 50m = 11067.7 m. Approximately 11km from the camera.

Don't you see that it is not needed? From a human point of view, the Earth is not curved enough to make any difference to the human eye..
