French mathematician Jean Paul de Gua de Malves discovered this three-dimensional analogue of the Pythagorean theorem in the 18th century.
If a tetrahedron has a right-angled corner (such as the corner of a cube), then the square of the area of the face opposite that corner is the sum of the squares of the areas of the other three faces.

In March 1999, fisherman Steve Gowan was fishing for cod off the coast of Essex when he dredged up a green ginger beer bottle with a screw-on rubber stopper. Inside he found a note:
Sir or madam, youth or maid,
Would you kindly forward the enclosed letter and earn the blessing of a poor British soldier on his way to the front this ninth day of September, 1914.
Signed
Private T. Hughes
Second Durham Light Infantry.
Third Army Corp Expeditionary Force.
The enclosed letter read:
Dear Wife,
I am writing this note on this boat and dropping it into the sea just to see if it will reach you. If it does, sign this envelope on the right hand bottom corner where it says receipt. Put the date and hour of receipt and your name where it says signature and look after it well. Ta ta sweet, for the present.
Your Hubby.
Private Thomas Hughes, 26, of Stockton-on-Tees, had dropped the bottle into the English Channel in 1914 as he left to fight in France. He was killed two days afterward. His wife Elizabeth and daughter moved to New Zealand, where Elizabeth died in 1979. Gowan delivered the letter to the daughter, Emily Crowhurst, in Auckland that May. Two years old when her father had left for the war, she was now 86. She said, “It touches me very deeply to know … that his passage reached a goal. I think he would be very proud it had been delivered. He was a very caring man.”

This is actually the second variation on How to write a comic when you have no ideas, not the third. I think I scrapped another, and that’s why I said this was the third, not the second.
I was out of ideas, so I wrote two comics about not having ideas. Now I’m left sitting here trying to think of what to say about this comic that I didn’t say about the last one.
The irony is not lost on me.
Note from Missy: And yet you managed to come up with ideas for another 9 years after this, which is pretty impressive. Also, I’ve always loved the “Scotty, you have to come up with something!” line.

Trying to imagine the scope of the cosmos is nearly impossible, but musician and artist Pablo Carlos Budassi decided to make a visual attempt by cramming the entire known universe into a single image. Using scores of satellite images and photos snapped from NASA’s rovers, he painstakingly pieced together many of the prominent features of the universe as observed from our solar system in the form of a logarithmic map. Logarithms are useful for understanding large numbers or distances, so in Budassi’s map each consecutive ‘ring’ around the circle represents several orders of magnitude further than the one before it.
Budassi was aided by similar (though less visually stunning) logarithmic maps produced by astronomers at Princeton back in 2005. In this map, our sun and solar system are seen in the middle, followed by the Milky Way Galaxy, another ring of nearby galaxies like Andromeda, all the way out to cosmic radiation and plasma generated by the bing bang on the furthest outskirts of the image.
You can see a much larger version of the map here and read a bit more about it on Tech Insider. (via I F*cking Love Science)
When you're using power tools to complete a big project, battery life is a big problem. You probably don't want to find out you need a battery swap when you're in the middle of drilling. Thankfully, Black and Decker has a way to give you a heads-up:...

Hovertext: I mean, it's a legitimate question in certain contexts.
About drunk dinosaurs, in fact.
Una colección de escarabajos puede causar aprensión en algunas personas, pero la selección que han hecho en el Museo de Historia Natural de Cleveland es especial.
Contiene decenas de ejemplares ordenados por tamaño, como suele ser habitual, pero si miramos atentamente a los especímenes nos encontraremos con un guiño simpático del entomólogo encargado de la sección: Una reproducción del mítico VolksWagen Escarabajo (Beetle en el original), pinchada en una aguja al igual que sus desafortunados compañeros.

Really, any specific threat will be more effective than saying that you’ll “get” someone. “I’ll get you for this!” Even as a kid that seemed way to vague. I know, you’re thinking that the vagueness makes it more threatening, but being clear about your intentions will make the danger seem more real, since they’ll be able to picture the specific act you’re threatening.
Also, making said threat from atop a throne of skulls will help.
Looking at the first and fourth panels of this comic illustrated the fact that a drawing that looks okay tiny can look really jacked up when you zoom in. A less lazy cartoonist would have redrawn it, but we all know I don’t roll that way, when I can be bothered to roll at all.
Note from Missy: I always love when there’s punctuation profanity, so I can play the “what word is that replacing?” game. (Also, did you know that a set of punctuation used to replace profanity is known as a “grawlix”? (Cue The More You Know music.)

OH MAN, so many cool people will be in attendance :)
