low frequency communication needs long antenna. fractals solve a packing problem of fitting the longest shape in the smallest space.
but mostly, bc they look cool.

the internship isn’t “free” you are paying for it with your time
no cost to the company for wasting your time, no serious incentive to invest in your success
if a they don’t have the funds to pay an intern well, that strongly signals of the current state of the company

Why are all the CNC controllers I see made by only a couple companies? What’s so complicated about them?
India consumed $3 billion worth of CNC machines in 2023, which includes 65% imported and 35% domestic products. This CNC machine consumption is expected to grow by 20% over the next 5–7 years.

extremely bullish on free-space optical communication becoming the principal connecting mode for QI.
negligible polarization scrambling in free-space will mean far higher bit rates.

quick review

-water stayed cold literally from 7:45am to 5pm
-1.2L feels like nothing when you’re sipping away through the day
-design and customisation were great

the shape plays a role to the extent that there isn't excessive capacitative/inductive interference between bends, distorting the resonant behavior of the antenna.
