- This is the connector on a Category 5 Enhanced, better known as Cat 5E, Ethernet patch cable used to connect a computer to a wired network. The cable has eight wires in four twisted pairs although in most cases only two pairs are used for communications. Each pair has a different distance between twists. This alternating distance reduces crosstalk, without affecting the characteristic impedance. The distance per twist is commonly referred to as pitch. Each pair contains between 51.7 and 65.2 twists per meter. How's that for dose of geek talk. Enough techno babel, here's some photo speak - Canon 7D, 1/40 sec @ f/5.6, ISO 800, 100mm macro focused at about 12 inches from the subject. Light is from one LED Litepanel.

Ascent
This is John Safer's sculpture, Ascent located at the entrance of the the Steven F. Udvar-Hazy Center. It honors the human endeavor of flight. I was lucky enough to catch this dragonfly just as it flew by with the 70 foot tall airfoil shaped sculpture in the background. Canon 5D Mark II, 1/1250 sec @ f/11.0, ISO 200.

Night Sleeper
- The leaves of the tree widely known in the U.S.A. as the Mimosa tree but more correct is the name albizia julibrissin or Persian silk flower. Its leaves slowly close during the night and during periods of rain, the leaflets bowing downward: its modern Persian name shabkhosb (شبخسب) means "night sleeper". In Japan its common names are nemunoki, nemurinoki and nenenoki which all mean "sleeping tree". Source Wikipedia. Canon Digital Rebel, 1/320 sec @ f/5.0, ISO 400, 100mm macro.

You Like Tomato and I Like Tomahto
- As Louis Armstrong would sing - "You like tomato and I like tomahto." The tomatoes or tomahtos, take your pick, are in season. Nothing like a fresh vine ripe tomato, or tomahto, for a taste of summer. Canon 7D, 1/40 sec @ f/5.6, ISO 800, 100mm macro.

Missing Tooth
- Robert lost his first tooth this week. It came loose while he was biting into an apple and then he pulled out himself. He's a tough guy. Of course he got a visit from the Tooth Fairy and got $5.00 for his tooth! Canon 7D, 1/30 sec @ f/2.8, ISO 800, 100mm.
