Today I learned that the “banana equivalent dose” is a way of comparing the relative level of radiation exposure of different activities. For example, a dental x-ray is the equivalent of eating 50 bananas. A transatlantic flight is like eating 800 bananas.
A lethal dose of radiation is equivalent to 35 million bananas. Which is funny, because it only takes consuming about 200 bananas to die of potassium poisoning.
The video is enjoyable, and (spoiler) it also happens to be a performance of 4’33”, so you get a two-for-one. You’re welcome.
This excerpt from a commencement speech by David Foster Wallace always stops me cold and forces me to reconsider my perspective. He discusses the mundanity of adult life and the ways in which our conscious choices about how we perceive the world around us shape how we find meaning. See also: Tim Urban on empathy.
This is a gobsmackingly incredible visual exploration of deaths related to World War II and other conflicts. You’ll start watching and it just keeps getting more insane, and you can’t stop until the end. Well worth the 18 minute run time. I thought I understood the scale of the conflict — to the extent anyone can — but I had no idea.
The departing commander of the ISS provides this awesome comprehensive tour of the station. Its interesting to see how every inch of space in all three dimensions is utilized, as well as just how big the station is.

But the potential augmented future portrayed in this short film is a frightening exploration of what AR might bring. The simple act of brewing a cup of tea becomes an exercise in sensory overload.
