Venus Transit 06 June 2012

To my horror when i got up at 04:49 the sky was completely clouded, and thought that this once in a lifetime opportunity had passed. Fortunately an hour later it was good enough to see the transit. And then final contact at around 06:51. The transit of venus, from sunrise, around 04:34 to last contact…

Solar Panel angle

As we have added solar power to our cabin, i got interested in what would be the optimum angle of the solar panels to the sun. Right now they are mounted facing south at 90 degrees to the horizon. Not very good for summer weather. After a bit of searching i found a couple of…

Bold theta in latex

I had issues trying to get theta to be a bold symbol in latex, niether \bf or \mathbf seemed to work. Searching the internet gave no real solutions but after asking a cooluge he proposed i use: From=To

Moon Size on Film

Moon size with different leses The following images are 100% crops of the moon, taken with a Nikon D70s at different focal lengths. The Nikon has a 1.5 crop factor, so to get a similar image in 35mm film, you need to multiply by 1.5. Focal lengths marked TC are taken with a 2x teleconverter,…

Electric Field Nematic Alignment Of Fluorohectorite Clay Particles In Oligomeric Matrices

Electric field nematic alignment of fluorohectorite clay particles in oligomeric matrices Zbigniew Rozynek, René C. Castberg, Alexander Mikkelsen and Jon Otto Fossum Abstract We study the behavior of fluorohectorite synthetic clay particles dispersed in paraffin wax. We report wide-angle x-ray scattering related to electric-field-induced alignment of the embedded clay particles. The development of anisotropic arrangement of…

Active Structuring Of Colloidal Armour On Liquid Drops

Active Structuring Of Colloidal Armour On Liquid Drops [Link to article] Adsorption and assembly of colloidal particles at the surface of liquid droplets are at the base of particle-stabilized emulsions and templating. Here we report that electrohydrodynamic and electro-rheological effects in leaky-dielectric liquid drops can be used to structure and dynamically control colloidal particle assemblies…

Auora Borialis

You would think that living in Norway i would see this the whole time, but in honesty i have only seen it properly once, that was in October 2008, in Rondane. I was actually out looking for the meteor strom that was mean to be happening but ended up photographing this instead. This is a…

Star photography

I have attempted star photography a couple of times but so far this is the most successful attempt, this is a stack of photos (about 20) each photographed for 30s at 18mm/3.5 with a nikon D7000.
