Photos to scan

Some pictures I've taken that I intend to add as soon as I can use a friend's scanner:

• Cranes:
  • International Crane Foundation, http://www.savingcranes.org/
  • Black-crowned Crane
  • Blue Crane
  • Common Crane (aka Eurasian Crane)
  • Red-crowned Crane
  • Whooping Crane
• Panavia Tornado (The pictures are rather low quality, but do include views with wings extended and retracted.)
• F-117 Nighthawk
• Aerial refueling
• Stonehenge (already has a few pictures, I might just skip it.)
• Bath, England
• Oxford, England / J. R. R. Tolkien
• Yak if it doesn't already have one
  • Oh bloody, I'm going to have to write the article too, aren't I? Unfortunately, I don't know Yak....
• Image:H-R diagram.png Not an actual photo to scan, but a diagram that could use some tweaking

WikiProject Astronomical objects

• Perhaps to add to the astronomical body infoboxes in "Observational data" or something like that:
  • Surface brightness
  • Range of apparent magnitude (for Solar System bodies)
  • Range of angular size and/or angular area (for Solar System bodies)
  • Maximum elongation (for bodies with orbits entirely within Earth's)
  • Possibly move from other sections: albedo, absolute magnitude (planetary meaning, for Solar System bodies)

Pages I just like

• Orders of magnitude
  • Orders of magnitude/template
• Various physics and math topics:
  • Barycenter
  • Derivative
    • Table of derivatives
    • Table of integrals
  • Escape velocity
  • Gravitational constant
  • Orbit
  • Orbital elements
  • Orbital speed
  • Synodic period
• Wikipedia:Rouse History of Mathematics
• List of Latin phrases

Possible future pet projects

• Babylon 5 & related
• $\delta v=v_{exhaust}\cdot ln\left(\frac{m_0}{m_0-m_F}\right)$
  • $m_0$ is total original mass, $m_F$ is mass of fuel consumed
  • What's the appropriate article for this one?
