ITT: ppl who take jokes too serious.

If only Russia left Ukraine, everything would be much easier…

Bubble sort. It’s the only one I really understand and know how to implement.

/s to be sure

Shared gold means no silver medal. (2 gold, 0 silver, 1 bronze)

Shared silver means no bronze medal. (1 gold, 2 silver, 0 bronze)

Shared bronze means shared bronze. Also some disciplines give out 2 bronze medals by default, which is the reason for the high number of bronze medals. (1 gold, 1 silver, 2 bronze)

Is there an updated version of this image? There happened a lot in the last 2 years!

Not only if some one complains… Just mentioning the OS which must not be named summons all this guys.

I use arch btw.

Russia could deescalate quite easily…

To add further more: often also 810 or 820 numbers exist, where a phone call might have a toll up to 10 or 20 cents per minute respectively. With 900 numbers you usually dont know, how expensive they are, when only looking at the number.

Ctrl-A + Enter once got me an extra work at school, because the shitty PC froze for 20 mins…

And he waddled awayyyy, waddle waddle waddle

Fuck snow! Need more warming! /s

They get eliminated at first sight!

$ 50

Do you call this fifty dollars, or dollar fifty?

Lots of stuff is written differently, than it is spoken. In case of the date it is weird, not to go from biggest to smallest or vice versa. I guess you are used to it now, but for me it would be the same as putting seconds before minutes or inches before feet.

Also you are totally not spez!

Are you sure about that? From m/s to km/h you multiply by 3600 (for the time) and divide by 1000 (for the distance) which leads to a factor of 3.6.

Personally i always remember 25 m/s = 90 km/h = 56 mph because of the somewhat round numbers.

Sooooo, wavelengths (λ) become longer when something moves away (redshift) and become shorter when something moves towards you (blueshift).

For a red flag (λ0=610nm) to become a green flag (λ1=549nm), it has to move towards you quite fast. But how fast is ‘quite fast’?

Using the formula

flag_velocity / speed of light © = difference in wavelengths / starting wavelength

we get

flag_velocity = (610-549) / 610 * c = 61 / 610 * c = 1/10 * c

This means: the flag has to move with about c/10 = 30 000 000 m/s = 108 000 000 km/h = 67 108 100 mph. Yeah, that’s quite fast.

(Disclaimer:

1. use info on own risk

2. values for λ were chosen in a way to make calculations easy. There is no info on what shade of red or green the flag is. The final result will be about the same.

3. With speeds at around 10% of c, I should use the formula considering the relativistic doppler effect… However, i wont. Thanks.)

How are you in november already?!?!? ^/s

Doesn’t matter what Ukraine is doing - Russia should just fuck off and go home.

Unfortunately your explanation is wrong: the reason why satellites in low earth orbit fall back to earth is, that in those heights (about 500km above earths surface) the thin remaining atmosphere creates drag and slow the satellites down.

About gravity: gravity is the reason, why satellites even stay in orbit and keep circling the earth. Without gravity, all the satellites would just fly away.
