This is an actual experiment that has been going on for 3 days. It's a whole raw egg with it's shell dissolved in white vinegar. The only thing holding the egg together is the thin but tough membrane. We take the egg out of the vinegar each day and measure it's circumference. The egg has been swelling daily as the vinegar passes into the membrane to balance the acidity of the vinegar. This is supposed to teach the osmosis action of cells. It is my older daughter's experiment and she has yet to touch the egg as she finds it quite disgusting. I found the whole thing fascinating and Rosie is looking forward to popping it tomorrow.
View Large on black to see how disgusting it really is.

Some experiments with the Hasselblad H3D II 39 (very fun)
Self Portrait of Adam Flikkema the scientist.
I picked up a 3-drawer McCobb chest and base recently, and started playing around with the short 2' base - I put a cabinet on it, and then put it in this spot, where a small pedestal with a studio ceramic piece sat before. Now the chest of drawers is sitting on the floor in the bedroom, and I wonder if this combo works here? Kind of interrupts the entry to the living room... but kinda cool, too. (we're having a reception next weekend, prompting all this re-arranging)
Watercolor sketch quickly done on a small scrap of paper. I was attempting to render the glow from a candle. I was painting mostly wet into wet and kind of like the way the water and pigments flowed to create this image.

This is my "Experiment in LEGO". This was done in Lego Digital Designer (LDD) in the LDD Extended mode. Each of the colors is from the color chart in the sequence presented in the LDD program. The LXF file is included if you are interested. The render was done with POV-Ray. The back screen is made of 8x16 tiles in Metalized Silver. What is missing from the colors is the Metalized Gold, it seems C3PO took off with it! Also missing is the last 4 Legacy colors, I was lazy, wanted to keep it just to four rows.

A compact experiment aimed at enhancing cybersecurity for future space missions is operational in Europe’s Columbus module of the International Space Station, running in part on a Raspberry Pi Zero computer costing just a few euros.
“Our CryptIC experiment is testing technological solutions to make encryption-based secure communication feasible for even the smallest of space missions,” explains ESA software product assurance engineer Emmanuel Lesser. “This is commonplace on Earth, using for example symmetric encryption where both sides of the communication link share the same encryption key.
“In orbit the problem has been that space radiation effects can compromise the key within computer memory causing ‘bit-flips’. This disrupts the communication, as the key on ground and the one in space no longer match. Up to now this had been a problem that requires dedicated – and expensive – rad-hardened devices to overcome.”
Satellites in Earth orbit might be physically remote, but still potentially vulnerable to hacking. Up until recently most satellite signals went unencrypted, and this remains true for many of the smallest, cheapest mission types, such as miniature CubeSats
But as services delivered by satellites of all sizes form an increasing element of everyday life, interest in assured satellite cybersecurity is growing, and a focus of ESA’s new Technology Strategy for this November’s Space19+ Ministerial Council
.
CryptIC, or Cryptography ICE Cube, - the beige box towards the top of the image, has been a low-cost development, developed in-house by ESA’s Software Product Assurance section and flown on the ISS as part of the International Commercial Experiments service – ICE Cubes for short. ICE Cubes offer fast, simple and affordable access for research and technology experiments in microgravity using compact cubes. CryptIC measures just 10x10x10 cm.
“A major part of the experiment relies on a standard Raspberry Pi Zero computer,” adds Emmanuel. “This cheap hardware is more or less flying exactly as we bought it; the only difference is it has had to be covered with a plastic ‘conformal’ coating, to fulfil standard ISS safety requirements.”
The orbital experiment is operated simply via a laptop at ESA’s ESTEC
technical centre in the Netherlands, routed via the ICE Cubes operator, Space Applications Services in Brussels.
“We’re testing two related approaches to the encryption problem for non rad-hardened systems,” explains ESA Young Graduate Trainee Lukas Armborst. “The first is a method of re-exchanging the encryption key if it gets corrupted. This needs to be done in a secure and reliable way, to restore the secure link very quickly. This relies on a secondary fall-back base key, which is wired into the hardware so it cannot be compromised. However, this hardware solution can only be done for a limited number of keys, reducing flexibility.
“The second is an experimental hardware reconfiguration approach which can recover rapidly if the encryption key is compromised by radiation-triggered memory ‘bit flips’. A number of microprocessor cores are inside CryptIC as customisable, field-programmable gate arrays (FPGAs), rather than fixed computer chips. These cores are redundant copies of the same functionality. Accordingly, if one core fails then another can step in, while the faulty core reloads its configuration, thereby repairing itself.”
In addition the payload carries a compact ‘floating gate’ dosimeter to measure radiation levels co-developed by CERN, the European Organisation for Nuclear Research, as part of a broader cooperation agreement
.
And as a guest payload, a number of computer flash memories are being evaluated for their orbital performance, a follow-on version of ESA’s ‘Chimera’ experiment which flew on last year’s GomX-4B CubeSat
.
The experiment had its ISS-mandated electromagnetic compatibility testing carried out in ESTEC’s EMC Laboratory
.
“CryptIC has now completed commissioning and is already returning radiation data, being shared with our CERN colleagues,” adds Emmanuel. “Our encryption testing is set to begin in a few weeks, once we’ve automated the operating process, and is expected to run continuously for at least a year.”

Experiment time again. An old photo I took in August 2008 in Gamlingay, Cambridgeshire. This secene features the Church of St Mary the Virgin, and the Wheatsheaf public house. I have tried to make it look more old fashioned by adding some crease effects, any feedback welcome.
I didn't have a clear layout in my head when I started so I threw so black Lego shapes in abstract arrangements (bottom row; sometimes doing test shots like these hits upon a cool image that I can develop and refine but other times it just doesn't catch). I wasn't feeling those Lego ones so I tried pot plants (middle) then lastly old tree stumps I have outside (top).
One of many men helping us switch out flooring, move into the house, out of the Alaska house. Some expressed their dissatisfaction with my camera with awkward gestures. This chap did not.
But he did not pose. I just kept clicking. Moving is such fun.

Thanks for looking as I experiment. Hid this during a bit of anxiety; thanks again for the encouraging comments.
film. inspired by this guy's work, he is just wonderful. I just wanted to try this out and see what would happen.
n. *Experiment
1. the act of conducting a controlled test or investigation

My resolution in SL has been rather weird lately... I must have messed with some settings somehow... But i've been playing with SL lights a lil and just figuring things out.
I'm so used to operating on low settings that it's a whole new world doing lights and stuff :3 fun though!

I took this shot when doing some experiment with Vimal. I gave him an apple and asked him to make some weird expressions while eating apple and he did wonderful Job. This is just an experiment; I gonna give him PIPE or CIGAR next time.
Thanks for appreciating my pictures, looking forward for your advices and comments on this picture as well...
Bouquet and thorns are equally welcome
This is a solarized version of another photo.
Sorry I have not been around a lot. After the accident it was hard to go out and shoot anything as I could not walk very far and I was too cranky to get a good perspective. Also we are getting ready for our first craft fair next Sunday and I have been matting photos and hand making cards and bookmarks....wish us luck.
I've been up all night trying to get some work done, and thought I'd take a break by playing around with some photos in GIMP. Due to lack of sleep, my judgement is a little impaired and I thought I'd try two things I told myself I'd never do.
This is number 2: add text (let alone poetry) to an image. I remembered this poem when I was looking at my contact sheet and just couldn't resist. You can tell I wasn't really committed to the idea because the text is so small, you probably won't be able to read it unless you view it large. Do you think this works, or is it just lame?
btw the poem is:
春雨や傘さして見る絵草紙屋
正岡子規
which translates roughly to:
spring rain,
browsing under an umbrella

Since last month i own a new set of GND e ND Hitech filters...I'm still practicing with them and this is one of my first pictures..
As in the title, this is an experiment and i don't know if i like it or not...
What do you think?

Profession gardien de Zoo à mi-temps, il faut assurer le repas bi-hebdomadaire des tardigrades de l’expérience Cell Science 4 🔬. Les chercheurs étudient les effets de l’impesanteur et de l’environnement spatial sur ces créatures microscopiques qu’on surnomme parfois oursons d'eau. L’espèce la plus grande peut mesurer jusqu’à 1 mm de long, mais en général ils sont microscopiques… Ces créatures sont incroyablement résistantes, capables de survivre à des environnements extrêmes sur Terre comme dans l’espace : certains sont revenus de plusieurs jours à l’extérieur, dans le vide, avec des températures de +100 à -100 degrés, sans un dommage... Dans le cas de Cell Science 4, les scientifiques essayent d’identifier les gènes qui leur permettent de survivre durant des séjours plus ou moins longs dans l’espace, et d’évaluer comment l’utilisation de ces gènes change au cours des générations dans le but d’exploiter pour les humains les secrets de leur incroyable résilience !
Feeding the tardigrades! 🌱 Researchers are investigating the effects of microgravity on these microscopic creatures, also known as water bears, through an experiment called Cell Science 4🔬 #DYK the largest tardigrade species is just over 1mm in length and they're incredibly hardy – surviving extreme environments in space and on Earth. In this case, researchers want to characterise the genes that allow tardigrades to survive during short and long periods in space, then assess how the use of these genes changes across generations Maybe we can harness their secrets!
