Why Stop Signs Have Eight Sides

An interesting read with some quite reaching statements. For example the idea that the more sides a sign has, the more important it is. That's a stretch.

Do Not Enter signs are typically circles -- infinite sides

Erhm... no. One side. A circle has one side.

But they're typically not included in this hierarchy for some reason

yeah, that's because the hierarchy is completely made up.

It also depends on the geography. For example, the general rules in most European countries are (note that these are infinitely more consistently used than in US/Canada):

  • Red circle: Mandatory rule, e.g. "do not enter", "no parking", etc.

  • Blue circle: Mandatory rule, specifically used for direction of travel, e.g. "traffic must turn right"

  • Red triangle (point up): Warning, e.g. "hidden entrance", "gravel road ahead", etc.

  • Red triangle (point down): Yield. Note that this shape is chosen for the same reason as the stop sign: Cars from other sides can see that the others are to yield.

  • Red octagonal: STAAAAP!

  • Red or blue square: Informational, e.g. outlining the lane rules at an intersection, distances to nearby cities, or hospital/airport/seaport, etc.

In short, I'd take paragraphs 2&3 as pure speculation and not quite facts...

The Coffee Brand That is a Total Lie


...contains one of the funniest accidental turns of phrase I've seen Dan write in awhile:

" Business was good — until the Great Depression kicked in. Nuts, "....

Okay, I'm a juvenile. I can live with that! :-)

No RSS feed anymore?

Mr. Lewis, u/MrDNL, was it intentional, or is there just an issue? http://nowiknow.com/archives/feed/

Great site, but I just can't keep up with everything without RSS.

Just learned how to blow my nose... I am 32, what other “easy” things should we know that are never really explained.

Have had a cold for a couple of days, my wife just told me to blow my nose, so I did. Got some tissue and blew my nose like 3 times, no change. Then she told me to close one nostril while blowing into the tissue... magic. I always thought that it was just something that didn’t work for me, vs me doing it wrong my whole life. What other things are we doing wrong and don’t know?

caveat paper user

These should be good warnings in latin caveat charta usor (Caveat paper user) adnuntiaveris user chartam (warning paper user) usum exponere chartis vestris (paper use at your own risk) periculum incidere chartae (risk of paper cut) Conscidisti charta mortis (paper cut of death) per cartam vulneratus (mortally wounded by paper)

Looking for the "Hershey's" story.

I think I remember reading about Hershey's chocolate in a [NIK] article. However I can't find it, maybe I lost it. Can anyone help me, or am I dreamembering? TIA
