This is a quiet space.

elkement is thinking about well-known theoretical physics. Relearning and reviving the basics again and again. Inspired by the aesthetics of vintage patent drawings and Sir Roger Penrose’s handcrafted sketches, I am searching for the nexus of science and art. I am experimenting with math software SageMath and descriptive geometry / freehand drawings. Snippets of science articles – incl. my own – serve as raw material for my Found Poetry.

elkement is an amalgam of my first name, Elke, and my long-term nickname Subversive Element. (Legal notice and contact for this blog)

I know, it’s confusing. It’s likely you came here, following a link to an article on our ice-tank-powered heat pump system or on hacking Windows Public Key Infrastructure. You can find these in the Cyber or the Energy category.

I am a self-employed engineer (cybersecurity/energy). Education: MSc/PhD in applied physics, MSc in renewable energy engineering, self-studied computer geek.

The tagline of the blog refers to this quote by Richard Feynman (see this article for more context).

“It does not do harm to the mystery to know a little about it. For far more marvelous is the truth than any artists of the past imagined! Why do the poets of the present not speak of it? What men are poets who can speak of Jupiter if he were like a man, but if he is an immense spinning sphere of methane and ammonia must be silent?” –Richard Feynman

Physics. I am thinking out loud about well-known mathematical physics. Re-learning an re-viving the basics again and again. Inspired by series of textbooks, written by a single person who aspired at covering all of physics, like Roger Penrose, Landau&Lifshitz, David Tong.

Art. I create Found Poetry of my own science articles and of internet search terms. Inspired by the magic of the math underlying theoretical physics, I craft digital art and drawings.

Cyber. I built it, I protected it, and I hacked it. I have been implementing and supporting Windows Public Key Infrastructures. Finally I turned to the red side.

Energy. I used this blog to publish research about the heat pump system we’ve developed. The heat source is a combination of an underground water/ice tank and a ribbed pipe solar/air collector. I was in charge of simulations and data analysis.

History of Science and Engineering. I am standing on the shoulders of giants.

Web. Meta: How this website has evolved. On internet culture.

Life, the Universe, and Everything. Thoughts about Life, Work, Science, Technology, Business, and all their intersections – in spirit of the original name and tagline of this blog:

Theory and Practice of Trying to Combine Just Anything
Physics versus engineering
off-the-wall geek humor versus existential questions
IT versus the real thing
corporate world’s strangeness versus small business entrepreneur’s microcosmos,
knowledge worker’s connectedness versus striving for independence

  1. Hello, I have just found your website because I have a Stiebel heat pump and a Raspberry Pi.

    I want to know If you are still using the tools descibed in your messages.

  2. Hello i have lost my pfx for efs files. My ssd is burned, and i have only one copy in a pen, but pfx is lost. I have some password for wallet crypto, Can you help me? I can give you some btc of this wallet . thanks

    1. I am very sorry, but if your user profile is lost (which was on the system drive) and there is no PFX backup, then there is no way to recover your private key.

  3. Trump’s election pushed me back to my blog (probably temporarily). It looks like you’re the one surviving member of the blogs I followed when I was here regularly. Nice to see. Take care. -WBD

  4. Hi there! I just wanted to say that you have an incredible blog, and that I find your writing to be insightful, refreshing, and apt.

      1. Some years ago, after coming to live in Puerto Rico, I builts a solar water heater from pvc water pipes, sheets of glass and a too cheap plastic 40 gallon tank. Very economical until the tank burst under the 100psi (metric ????) water pressure in the mains. I had to buy a pump and make a feed tank, reducing the financial benefits somewhat ! They call it “La Perla”, a former slum quarter of Old San Juan, due to the use of corrugated iron sheets. Your things are so much more professional.

        1. 100psi is nearly 7 bar – yes, that’s a lot! :-)
          Of course a simple solar system utilizing only gravity has the advantage of being independent of the power grid. I have seen such systems on the Canary Islands for example – and I think they work quite well given a proper tank.
          Our system is optimized for harvesting energy in winter, via convection of air – so these are different requirements anyway.

  5. Hi Elke, I had promised to send you an article on living off grid in Canada. Unfortunately I could not find the one that related to some of the elements of your system; I don’t think I have a copy of the magazine on hand any more (looked every where). The magazine is no longer in publication, and I couldn’t find any archives to it on line. Here is the only article I could find… it might be of interest.

    1. Thanks a lot, Michelle, for sharing this! Yes – this is impressive! What I find most intriguing is that these home owners believe in simplicity, there are no allusions to “smart home” etc. I like the simple “air conditioning” and the living roof in particular.

      1. It is really interesting, and I think more common than we know. Most of Ontario is covered in bedrock so the cost of building and trenching in utilities is quite high. Going simple helps!

    1. (disregard one of these comments–I’m having some internet connection problems today and thought I lost this as it was posting–couldn’t remember what I wrote exactly while recreating the comment!)

  6. Hello Elke.
    Thanks for the like on my calculus without limits post no. 5
    I am following your blog now.
    Did you read the calculus no. 4 one on trig? I am still not sure if there are holes in the argument.
    I shall have another read of your spinning top post. I never felt at the time that the maths shed any real light on the phenomenon.

    1. Thanks for your comment and the follow – and for pointing me to your post. For other readers, here is the link: http://howardat58.wordpress.com/2014/09/15/calculus-without-limits-4-trignometric-functions-cosine-and-sine

      I like your derivation, and I left a version of mine (that I consider similar) in a comment … I hope it is not too off-topic or I don’t consider too many things as given and a pre-requisite that you wanted to avoid in your derivations. But as a physicist (or probably just impacted by the way I learned to deal with circular motion and which I found really useful) I can never resist replacing sine and cosine by an exponential function.

  7. Food for thought, food for thought when that is all that life has left to me when I have lived it almost to termination. I thank you.

    1. I duplicate the reply I left on your blog now – just to set expectations for other award bestowing bloggers :-)
      Thanks – I am honored to be in *your* Top Ten list!! I appreciate the award but be warned that I usually subvert the acceptance process and I don’t play by the rules ;-) as if anybody did we had a major issue with an exponential inflation of nominations!

  8. applied physicist, Star Trek geek, The Force, quantum field…hmmm….in that case…we have something in common then…and i thought i was the only one who stays awake sometimes thinking of those things! great posts, elke…long may it continue!
    PS im an electronics engineer by trade, and yes, physics was also a part of my studies, too..albeit in a very much watered down version of what you studied!

    1. Thanks a lot for visiting and commenting! I have always been amazed by the large number of people with similar interests and even careers I have stumbled upon … on the internet but even as colleages in projects. Actually I feel that the “geeky physicist working in IT, with a penchant for sci-fi and philosophy and still waxing nostagic when reading about physics” is nearly a cliché :-D

  9. Hey,
    Just happened to run into your blog. You have got a beautiful space running here. Loved your work. Its very subtle. I guess I will be hanging around here a lot. :) Great work

  10. Hej Elke, nice new photo! After summer recess I have a post scheduled for September. Keep in touch – always appreciate your comments. Venlig hilsen fra CarnotCycle.

  11. Glad you dropped by at my blog (and followed!) – via David Yerle – as it allowed we to find your blog. It looks wonderful. It will be a pleasure to follow. Thanks!

    1. Thanks a lot – I am honored! I have seen your thoughtful comments on David’s, Steve’s and livelyskeptics’ blog – your blog meets the expectations raised by these comments :-)

    1. You’re welcome! Fortunately there is Google Translate!
      To other readers: Despite the cryptic nature of this comment ;-) it is not spam. Check out digitalhegemon’s blog!

    1. Thanks – I feel honored to be nominated by somebody who can write so well!

      However, the conditions for participation are really tough. First I need to reveal the darkest secrets my soul holds by answering questions like “What is your favorite animal?” and second (and worst) this propels me into the acceleration-of-exponential-growth business. If every blogger nominates 5 other blogs and the delay time is about a week, then in about 15 weeks everybody on this planet will have been nominated.
      But I am only standing on the shoulders of giants here:
      http://millenniumconjectures.com/2012/10/15/the-blahs-2-millard-fillmores-bathtub/ .

      However, I think I have found the clue for beating exponential growth ,-) Stay tuned, I am going to reply with a full post in due time.

  12. the elkement is talking about energy and consulting, have you not always been working in the energy business – and in consulting? anyway, i read about Prof. Z.’s “Quantum Entanglement of High Angular Momenta” on the web and i think what happened to the red website? – and see its still there! nice. and fun. and even updated, whatever website resurrection means, since it wasnt offline. but who am i to split elkemental hair? This must be one of the three remaining websites in the world where you can leave a comment without having to register a user account and providing half of your life in the profiling process or surrender your facebook details. free unprofiled commenting and communication should be set down as a human right. happy resurrection! and thanks for all the fish

    1. Hi Fuzzi :-) Yes, and the red website (I cannot resist to add the URL: http://subversiv.at) is one of the few remaining sites in the universe that does not allow for commenting at all, and there is no feed to subscribe to. So I need to compensate for that and keep this blog open.
      Actually the site was nearly offline: I have removed a lot of the links from the main menu though the pages were still there. Some of the pages have not been resurrected yet, I am working on this (I really call it “work” – how un-subversive) while I am writing this blog.
      Re energy and consulting business: Consulting – yes, energy – no (just started). Might depend of the definition of energy maybe – subversive energy or energy as in thermodynamics? ;-)

  13. Hi curtain raiser, thanks for stepping by! I have just scrolled through your awesom blog! Are you probably going to blog on your views on science / why you “left” biology? I would be really interested. Are you still interested in chemistry or biology and do you hope to find something science-related behind your curtain? I have sort of reconnected to my roots now – I am in the startup-phase of working as a consultant in renewable energies. But I will require much more navel-gazing (and related blog posts) in order to rethink and reprocess what has happenend on the way ;-) And this time I have promised to myself not to rush through this phase of change – as I always did when I made a career change in the past.

  14. Hi Elkement, thanks for the follow on my blog. I’m also at the navel-gazing stage but took a slightly different path than you to get to this point. Whilst my ultimate career path had nothing to do with science, I too started off as a science major having earned an honours degree in microbiology after discovering my love for chemistry theory did not translate well into the lab. Nice to meet you!
