Welcome to c/science_memes @ Mander.xyz!
A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.
Rules
- Don't throw mud. Behave like an intellectual and remember the human.
- Keep it rooted (on topic).
- No spam.
- Infographics welcome, get schooled.
This is a science community. We use the Dawkins definition of meme.

Please be careful with two different things. Complex numbers have two components. Distances don't. They are scalars. The length of the vector
(0,1)
is also1
. Just asa+bi
will have the lengthsqrt(a^2 + b^2)
. You can also use polar coordinates for complex numbers. This way, you can see thati
has length1
, which is the distance from0
.The triangle in the example above adds a vector and a scalar value. You can only add two vectors:
(1,0) + (0,1)
which results in(1,1)
with the proper length. Or you can calculate the length/distance (absolute values) of the complex numbers directly.
