This experiment demonstrates the shift in color from yellow-green to blue-green of minerals containing the uranyl ion in conjunction with carbonates.
Uranyl nitrate was combined with NaCl and recrystallized on the glass rod. Behind it is a specimen of meta-autunite from the Daybreak Mine in Spokane WA, USA. Meta-autunite is a uranyl phosphate mineral.
Uranyl nitrate solution (0.25M) was combined with a sodium carbonate solution (1.25M) and was used to rehydrate some DAP Plaster of Paris mix which was set in a square mold.
Initially (when still wet), there was no fluorescence but after the calcium sulfate re-hydrated (and the mix produced CO2? bubbles), the resulting plaster fluoresced a bright blue-green, typical of carbonate based uranyl minerals. Behind the plaster square is a specimen with a coating of andersonite from Yellow Cat Mesa in Grant County UT, USA. Andersonite is a hydrated sodium calcium uranyl carbonate.

Much appreciation to Gordon Czop for the uranyl nitrate.

I have been experimenting with my D7K in Commander mode.
D7K with 50mm F1.8D. SB900 off to the left at 45 degrees and fired bare at 1/2 power. Built in flash turned off but used to trigger SB900.
Evening sun from right. Under exposed background. The star shape highlight on the bridge of the bass is a kick back from the bare flash.
EXIF supplied.
Straight from camera, just a crop.

Jackobluelite2 phosphor experiment with different concentrations of copper carbonate. Melted on aluminum trays on a steel plate.
Suspected Jackolite2 reaction:
S + Na2CO3 + CaCl2 -> CaS + 2NaCl + CO2 + 0.5O2
This sample was doped with about 0.02ml of Cu2+ from malachite.
Suspected phosphor: CaS:Cu in NaCl
Contains:
CaS:Cu (FL+PHOS! Pink/Blue, Blue >UVa,bc)
Shown under UVc light.

this is the first macro experiment
it is difficult to wrestle with the razor thin depth of focus of this lens

Packet blocking in a tennis-net experiment.
North-South traffic tangles with East-West traffic to form impenetrable traffic jams. When a packet hits a boundary it reverses and tries to go back to the opposite boundary. There is an avoidance protocol. Reference at www.ee.surrey.ac.uk/Personal/D.Jefferies/ps/
The different colours signify differing packet ages.
For a typical chaotic time series of the average packet age see

This is a snapshot of a dynamical process which displays intermittent blocking or "traffic jams". There is no random element in the simulation; it is entirely deterministic.
-Added to theCream of the Crop pool as most interesting.
Here are a few shots from an experiment my friend and I did about a year ago. The idea was to drop the dice from about 1.5 feet and get them in focus as they bounced. I think we did ok.
For me, fashion is a form of art. I wanted to take the time and experiment with some styles and colors to se what works and what doesn’t. Feel free to comment on what styles you think work best 😃

I haven’t done a Red Hat Society Experiment since November 2013. I’d sort of forgotten about my mania for pairing red and purple.
