Skin to skin messaging
please let it always end this way:
staying up late,
both of us soft and warm,
writing words on each other’s backs
with our fingers
like a lazy southern drawl.
and me with puckered brow,
trying hard to concentrate
and failing miserably each time,
because you with small grin
obliterate everything else
with each tiny delicate stroke.
The sky is blue because the incident light interacts with the gas molecules in the air in such as fashion that more of the light in the blue part of the spectrum is scattered, reaching our eyes on the surface of the planet. All the frequencies of the incident light can be scattered this way, but the high-frequency (short wavelength) blue is scattered more than the lower frequencies in a process known as Rayleigh scattering, described in the 1870′s. John William Strutt, Lord Rayleigh, who also won the Nobel Prize in physics in 1904 for the discovery of argon, demonstrated that, when the wavelength of the light is on the same order as the size of the gas molecules, the intensity of scattered light varies inversely with the fourth power of its wavelength. Shorter wavelengths like blue (and violet) are scattered more than longer ones. It’s as if all the molecules in the air preferentially glow blue, which is what we then see everywhere around us.
Yet, the sky should appear violet since violet light is scattered even more than blue light. But the sky does not appear violet to us because of the final, biological part of the puzzle, which is the way our eyes are designed: they are more sensitive to blue than violet light.
The explanation for why the sky is blue involves so much of the natural sciences: the colors within the visual spectrum, the wave nature of light, the angle at which sunlight hits the atmosphere, the mathematics of scattering, the size of nitrogen and oxygen molecules, and even the way human eyes perceive color. It’s most of science in a question that a young child can ask.
stunned by the news of his death, one by one they peeled off their jerseys and put them on wire hangers. that night, they hung those hangers in the branches of the tree in his front yard.
ok. i designed, i photographed, i wrote, i uploaded, i pinned, tweeted, booked, and tumbled. then i looked at french lingerie, read some pretty funny words from a man who actually writes for the Dallas cowboys, fulfilled and mailed an order, took on a design task, and decided to practice writing fewer than 200 words every day. not bad for a day that began with tears.
what did you do today?
