I love (loved?) 8tracks, but recently I have been annoyed at the poor choices on some songs. I listen to a lot of classic rock playlists, and lately a lot of tracks come from awful bootleg recordings of concerts, radio recordings with announcer’s voices, or some horrible fan remixes. This is even happening on…

Most men are pretty touchy about their hard-ons...

I played around with the simulation a bit (I am a secondary school science teacher). Some of the very early sections, which deal with physical traits, might be suitable for your daughter. But it soon starts dealing with DNA sequences, even at a simple level - so I am recommending this for middle schoolers, with some…

It reminds of the strange cult that formed after the famous “Time” strip in xkcd. It’s been more than two years, and they’re still going strong... http://forums.xkcd.com/viewtopic.php?…

Also (sorry, I had stopped reading at that point), your explanation after that is wrong:

You got a typo in the equation: you have swapped the superscript and the subscript on the left hand side: it should be : v_f^2, if my notation makes sense (I don’t know how to make them in Kinja!)

Late to the party, but I also really like the word “person”. In Greek, “persona” was the mask that actors wore when performing in a play. Some of the similar meaning has remained in our use of the word “persona”, but I find it fascinating that it just came to mean “a human being”.

And yet, in modern Spanish we have a word for avocado, “aguacate”, that sounds pretty much like the original.

I checked the map, and I came to say exactly that - glad that someone else had pointed that out. If anything, both Spanish and Catalan (and French, Italian, etc.) are dialects of Latin.

I always heard it as “Consider a spherical cow...”

That metaphor in the final paragraph is, just by itself, worth the price of admission.

Just use this for everything: https://xkcd.com/1406/

And another favourite (I found this thread late, but I am catching up): Numberphile. Great for your inner mathematics nerd. Here is one of my favourites: Graham explains Graham's Number

One that I haven't seen mentioned in the comments: Piled Higher and Deeper. Apart from a fun webcomic about academia, they publish great animations of research work explained by the scientists themselves, such as this:

I am sure Windlasher is glad that you are not touching his wife. ;)

I need to ask, because I am not seeing the credit anywhere... who drew this illustration? It is just magnificent!

Am I the only one who got a bit saturated by all the flourish, pop-culture references and multiple-clause sentences in that interview and thought, "Dude, you're trying too hard"?

There are a few things Google could add to make this even better(...)

Fair enough, no offence meant - I do help my kid out with his homework too, and I know what you mean by a "learning experience". I just latched on to the turn of phrase you used, which peeved me a little. But then again, I teach Secondary school, so I hope that by then kids do their own homework... Thanks for the…
