Hi all, I was reading an article in new scientistabout physicists suggestion the universe may be fractal, this kind of makes sinceto me since they’re rather good at describing leaves, trees coastlines ..basically anything well.. ‘natural / organic’. I know complex structures likesocial networks can exhibit fractal geometry as well; these structures can alsoexhibit complex and chaotic behaviours like weather patterns, neurons and othergraph structures. Navigating suchstructures could be considered NP-Hard (e.g. what order and how to manipulate proteinsin to fold them optimally). This got methinking about whether fractals could be used to turn the complexity of NP-hardproblems around and use it against them to *relatively* easily solve them. I must admit I'm no mathematician and haveno idea really where to start looking at this, so I thought id throw it outthere for you smarter guys to see what you make of it. Furbs

I’ve seen people blowing smoke rings and dolphinsblowing bubble rings I was wondering if it was a physical possibility to do thesame thing but through soil or sand or whether its too dense. What exactly is a vortex ring? Is it ashock wave of force carrying another substance or is it an actual particle flow Furbs

all i want to do is pickup the electromagnetic radiation using a pickup coil, or some other means which i think should have microwave frequency AC

Would it be possible to use a magnetron inplace of a primary in an induction system for wireless power transfer? I’minterested in microwave frequency resonance and i think this may be a good way of starting

Hi, I'm new too... so, about me... i'm a 24 year old just graduated student, looking at PhD's in the field of Artificial Intelligence. i have 2 degrees BSc in Robotics & MSc in AI with special games application. scientific interests include: most of physics chemistry (at least as far as i understand the equations) NP hard problems, Primes vortexes generally bridging the gaps between subject areas e.g. hydrogen fuel cell technology.
