I'll turn the Disneyland pics to Zz now! I spent the night at a place called Yamzi Ranch, it is a working cattle ranch. Using sound grazing methodology and with a lot of work they have also restored to nearly pristine condition a 20mi stretch of the Williamson river and wetland to create one...

By popular demand, here are the member photos only in alphabetical order. Continue to post pictures and comments in the member photo thread, and the pictures will be moved here. I want to say thank you to tribdog for getting this started. Hypnagogue has spent the last few days gathering all...

Are there any other geology/palaentology enthusiasts that like to do a spot of fossil collecting when they get a chance? Or maybe you don't like geology, but just think ammonites are cool? What were your best finds? Where are your favorite fossil hunting spots? Photos would be nice. I...

in some photos, mixed among the red white and blue stars, are green stars. Any idea what causes this?

Looking for advice? Willing to share your expertise with other PF members? Brave enough to share & discuss your own astrophotos? Then this is the thread for you. Enjoy! In all our cosmological discussions, let's not forget to actually go stargazing once in a while! :biggrin: Thanks...

Does anyone know where to find some high quality bubble chamber photos? Any information would be appreciated.

I'm pretty much okay with pair production but in the eqt we have that a photo gives an electron and a positron. If we do it the other way round we have an electron and a positron giving 2 photos in order to conserve momentum. Why do we not have 2 photos of energy for pair production ir order...
