Simple to state but very difficult to prove and it has taken more than 60 years to get close to a solution. Paul Erdos said "Mathematics is not yet ready for such problems" — so is it now?

Flames are ionised (i.e. charged) particles. If you have a strong enough electric field (which is really not the same as 'shooting electricity' as per the article) when the charged particles move through the electric field there will be a force on them perpendicular to their motion and to the field i.e. the flame will curve over into spiral.
That's for a magnetic field. Charged particles move along the direction of electric fields.
As a Peace Corps volunteer in 1999 the internet (very slow shared connection) was 2 days away and cost 1$/hour. Now it's a couple of hours away from where I lived, half the price and 10x faster. That needs to keep expanding. I tried explaining what the internet was to a rural friend. He had *seen* a phone once 10 years ago. Now he has one. The internet needs to go that way. People deserve access to information. Hey, maybe they'll start to figure out some of the solutions to their problems themselves instead of relying on people to tell them what to do.

Incredibly low? TFA quoted the median salary for a teacher in their mid 30s as $74,000 a year. I'm sure many people would be happy to trade their "incredibly low" salary for that incredibly low salary.
I don't know what article you're reading but the one linked in the summary says nothing about the median salary of a teacher. The number $74,000/yr, which I assume you pulled out of your ass, is about $30,000/yr inflated over the actual value. Sure, after 30 years of teaching I'd be making that much, but not in my mid-30s.
Yeah, I realize 20 years makes the memory a little hazy.
