“As someone with a background in physics, I was delighted to find out that the amount of caffeine in a person follows a half-life curve. Briefly, if you drink 300mg of caffeine, five hours later there will be 150mg left in your body. Five more hours later there will be 75mg, five more hours 37.5mg and so on.” (greysblog)
02. Pitchfork Interviews: Louis C.K.
“Because of Twitter and YouTube, you can have a fan base that stays there waiting for you, and they don’t necessarily have to be advertised to, which costs a lot. But again, it’s all very precarious because all of these people could grow up to another part of their life and just decide that they don’t like my comedy anymore.”
03. Jim Denevan etches impermanent geometric drawings into California beaches (above)
“Jim Denevan is a surfer, a sand artist, and a self-taught chef, the man behind the traveling outdoor dining experience Outstanding in the Field (previously). His geometric sand sculptures are made with little more than rakes and sticks and can span miles of North California beaches. The pieces take many hours to create but can often disappear much quicker as the incoming tide gently erases them from earth.” (colossal)
04. Lytro: A Camera That Couldn’t Care Less About Focus
“The basic premise of Lytro’s technology is pretty simple: The camera captures all the information it possibly can about the field of light in front of it. You then get a digital photo that is adjustable in an almost infinite number of ways. You can focus anywhere in the picture, change the light levels — and presuming you’re using a device with a 3-D ready screen — even create a picture you can tilt and shift in three dimensions. (I got a demonstration of the camera’s 3-D photos on a laptop and was blown away.)” (mashable)
