Hi! I am writing a short novel where the manipulation of Boltzmann constant is the key idea of the plot. I suppose this constant is not constant under especial conditions. A quantum computer use the increasing of available microstates in order to resemble a kind of "Maxwell's Demon" to reduce the entropy. What do you think about this? In science fiction, I have only read "The Practice Effect" by David Brin that is related also to decreasing entropy. But in this novel is not clear the mechanism and I want to give a more scientific point of view to my novel. I have written a half part of my novel and I want to publish online like ebook. I appreciate your opinions.

Well, I didn't yet try to use an electromagnet with this ferrofluid. I have an idea about to dismount an speaker to bring closer the ferrofluid and to use a periodical acoustical signal, e.g. using Audacity. It is not possible to open the bottle for safety reasons. When I have a ferrofluid that I can measure I will try to measure its conductivity. I mean to buy only the ferrofluid, not the complete kit that I have with magnets and bottle with ferrofluid and the other transparent liquid.

We can see here how the ferrofluid changes its patterns due to the influence of one or two magnets:

I try this with many glass at home and I didn't observe any fluorescence... but with virgin olive oil you can observe this phenomenon, also. I show this in the next photograph:

The lasers of 532 nm and 405 nm have 30 mW and 5 mW, respectively.

Thanks! Thanks for the explanation! I have this prism and I didn't know which was the reason of this fluorescence.

Hello, I made a fluorescence beam in a glass prism with two lasers of different wavelength. Did anybody try this before? With a 532 nm laser I saw a red beam inside and using another of 405 nm I obtained a yellow ray. You can see this experiment in this video: http://www.youtube.com/watch?v=8uOtIWizpZw Thank you!
