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

Totally agree with you!

Yeah, aluminium foil as cover does sparking wonders in that regard!

Also, the closer you are to the trailer, the safer you are! Because the speed difference is much smaller, when you touch the trailer!

It’s “ich_iel” on feddit.de
That’s exactly why testing is needed. You can calculate a ton of things but you only know through testing, when and where things fail. Then you iterate and test again.

Second motorola moto G. Imo they just work, not a lot of bloatware and a somewhat decent camera. I just dont get their model numbering anymore…
$ 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.
Am i stupid or is there an example of an ascii image somewhere?
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:
-
use info on own risk
-
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.
-
With speeds at around 10% of c, I should use the formula considering the relativistic doppler effect… However, i wont. Thanks.)

How manure.
