What have you learnt today?

[SwordsMaster]

I'm curious, what is the threshold concentration for allergies to fire?

[Hooahguy]

So its measured by a pollen count, which is a measurement of how many pollen grains are in a cubic meter of the air. The pollen count for where I live got up to almost 6,000 grains per cubic meter two days ago. That should tell you how bad it gets. A low number is in the double digits.

More on it here.

You are back in the ATL I see. Pray for rain, I remember those springs...

[Hooahguy]

Its supposed to pour all week, its overcast now and was drizzling this morning. Heres to a week of non-stop rain!

Wow, that's pretty spectacular. As drone says I hope it rains. Hang in there.

I've learned that if you ask random Americans on the street, a lot of them will not be able to tell you who Edward Snowden is or what he did. I also repeated some spanish but I'm not sure whether I learnt anything as I only have BDocs flying around in my head right now, back to work it is...
Oh, I also learnt that pollen can imitate smog if it comes in high density.

You got me reading. Apparently, pollen will explode if: concentrations equal 60g per cubic meter or more, a high heat source/flame is present, and the cloud is contained in some manner (in a building; surrounded on three sides by tall buildings, some form of tent). I think ALL of us would be allergic to pollen in the form of a fuel air explosion.

[Hooahguy]

Thankfully it poured last night, so the pollen washed away. It will be back though, it always does.

And Seamus Fermanagh that is mildly terrifying.

I assume that those who survive the oxidation of the pollen will have fewer problems with allergies however.

As for what I have learnt so far today, how to ask someone out in Spanish, that Schiller died young and that Goethe had a penchant for beauty and thought that prisms violate light because they tear it apart. I also learnt that when one is on a university with two campi in neighboring cities, one should be careful about signing up for Spanish courses because one might sign up for a course in the other city and then the uni plays inflexible and refuses to switch courses even though there is a course with fewer signups in one's own city that hasn't even started yet. I also learnt that the university shuttle bus that connects the two campi takes only 20 minutes. And the day isn't even over yet.

This one is misplaced. You should put it in the thread "What others learnt from you".

I didn't ask random Americans because I can't afford to fly there, I merely watched John Oliver report on it.

Again misplaced. This one should go to "What others learnt from John Oliver" thread.
