Description: This scanning electron micrograph shows the internal structure of liver tissue from an adult mouse. The sinusoids (vascular channels lined with endothelial cells) can be seen as pink structures running through the tissue. These contain red blood cells and Kupffer cells (specialized macrophages of the liver). Hepatocytes, shown in brown, are arranged in plates surrounding the sinusoids. Bile is secreted into the canaliculi, shown as green channels. These are dilated intercellular spaces between adjacent hepatocytes and bile flows through them en route to the small intestine.

it's been a part of me since i can remember

and i'm so tired of it

all i wish for

is to be common and simple

as others are

but i'm afraid that the only way to do it

is to never feel again

your skin

my bed

your touch

my warmth

your heartbeat

Our math teacher almost exclusively writes in this green marker.

Green is the opposite (complimentary color) of red.

She draws sinusoid graphs with them.

Sinusoid graphs look like water/waves.

Red or green water.

Recap: The following are important

Red

Green

Water (as we already knew from the arcs and Too Close for Comfort, etc.)

So let’s start putting all this stuff together. We’re given the circuit above and told that the frequency is 50 Hz. We’re then asked to find the current.

If you’re dealing with a complex network, you can combine impedances in series and parallel just as you can with resistance, capacitance and inductance. Impedances combine like resistances: for series combinations, they add, and for parallel combinations, the inverse of the total impedance is the sum of the inverses of the component impedances.

You can also use a more general version of Ohm’s Law to deal with impedances. Instead of just resistance, we can now relate voltage, current, and impedance.
