I have a non prof. interest in non linear dynamics, plasma, the very massive and not massive at all.
Also interested in number theory and set theory.
Just looking for folk to chat to, you're an interesting bunch... |

I prefer a banana sandwich to be fair. |

I think…. No… I’m definitely a little turned on… |

That's awesome, what did you find out?
I did ecology and stumbled into nonlinear dynamics looking at regime shifts, attractor basins and catastrophe theory. Suddenly physics was way more interesting. Burning my mind on point gravity atm |

"My field is metallurgy but always been fascinated by cosmology and astronomy etc. "
It's all pretty interesting tbh.
Along with point gravity, which seems erroneous. I'm trying to get my head round fluid electrodynamics. Fusion basically |

I've just been looking at that. Interesting phenomena. What do you think is going on. A recent study determined the 3mitred photons had a non poisson distribution. Quantum basically. |

I honestly haven't thought about it for years.. it was 20+ years since I graduated.
At the time I was bloody amazed I managed to trap the bubble in the degassing water using a standing wave . That blew my mind enough (considering the equipment we had(.  |

Awesome. Is there an established theoey of why isotopes and some elements decay. Hiw big does a nova have to be to produce uranium? |

Possibly
The overall result qt the time was a faint green glow in the bubble. I was in a total dark room.
I think at the time I did manage it.. but as the time passes I doubt whether I did or whether it was hope rather than reality. I did promise to buy the equipment needed and arrange a set up at home.. maybe once the kids are self sufficient I will.
It was also based on energy spikes, set frequencies.. boosting the power of the system with a potential divider.
I do recall being happy producing degassed water - which is much easier than you think. Such simple things made me happy back then.

If you had a glow it was coming from somewhere! I'd say you did it.
Since I became a full time carer I've started building valve amps, for fun. I play guitar and bass so it's a natural progression really. It's keeps my mind occupied and brings me pleasure.
It seems my ideas hold water at least are you familiar with cherenkov radiation? |

"I can solve exponential equations. Will that do?
Maybe how are you with einstein field equations and navier Stokes?
On first names with Claude-Louis and George Gabriel "
They're all over Lorenz attractors
I'm struggling with point gravity as used by einstein in his field equations. It seems that every massive particle would have an attraction for every other interacting particle. I need help arriving at a formulation of navier Stokes and nash's game theory to replace point gravity which describes the motion of perturbed fluids on the basis of their gravitational attraction only. I'm dyslexic I can't do the algebra but I can see the picture. |

What was your fave topic? You're gonna be pretty good at algegra I expect.
Lovely profile btw"
Haha yeah I guess so but I think I found the quantum stuff the most interesting as that's often where the crazy shit happens. Photonics is pretty fun too. Especially when you get to play with lasers  |

uranium and all the other heavy elements are now thought to be formed in a kilonova , two neutron stars colliding . It was previously though they were formed in supernova explosions but that theory has been mostly disregarded in the last few years . |

Some time ago now but I studied a load of stuff*. Then since then I have read a load of stuff. And spent nearly 40 years making computers and computer based systems do things that they weren't really designed to do.

I find the quantum stuff really interesting precisely because of that crazy stuff. I understand some of it, like quantum tunneling. The double slit experiment and entanglement are a real challenge, sometimes I think I have it bit I really don't. I'm trying to get to grips with the standard model atm.
Gravity waves are pretty interesting at the moment I think. I find the concept pretty amazing.
What did you do in photonics?

"I'm learning coding online..just got myself a 3d printer "
That's so cool. I've always been amazed at the virtual environments programmers create and the speed and precision cnc fabrication. Being able to print objects directly is incredible. I'm old enough to remember type writers and did a little print setting and lathe operation. |

I did read an article a while ago about superfluids in neutron stars and how heavier elements could crystallise out of them. I'm not sure how that corresponds with the gravity wave data. Certainly mass is lost in neutron star collisions, I thought the prevailing view was that it was converted to energy. I'll look up kilonovas. Thanks |

Literally so much to learn. From just an interest in astronomy in turn leads to dozens of other fields which are equally as mind blowing. Unfortunately with only basic secondary school mathematics at my disposal I doubt I'll fully understand alot of it. |

I'll watch it!
I read chaos and the selfish gene as a kid. In my experience the concepts come before the arithmetic, which in fairness even einstein struggled with. I wonder how many insights have been assisted by pharmacology over the years  |

If it's physical the maths is just a description, a tool. The understanding and concept comes before the maths. |

Correct. I have a decent grasp of the concepts which gives people in my position the title of Quantum Storyteller. A basic understanding of the principles but not from a mathematical point of view. Concept understanding will only get me so far. And if the forefathers of quantum mechanics say it's a mess what chance have I got |

It's a tricky one. Einstein founded quantum physics. His teachers at University thought he was a twit. His family had to assist him in finding a job. He wrote his first paper as a patent clerk which was generally overlooked. He clearly struggled with the maths and conducted thought experiments of the principles which he would later formalise into general relativity using Riemann tensor matrices. QM none really understands at the moment but the maths seems to work OK up to a point! Most are familiar with to shrodinger's cat, hiwever Heisenberg's uncertainty principle is far more revealing imo.
An area I'm particularly interested in is non linear dynamics. Chaos basically. To mathematically describe and predict chaos or nonlinear transitions between alternate states is impossible at the moment. However we can all recognise fractal patterns. Emergent phenomena are familiar beautiful and commonplace. The basic concept underpinning evolution is disarmingly simple and yet it evaded detection until Darwin and Wallace glanced in that direction. |

I literally put James Gleicks book back on the shelf in a second hand book store the other day and bought something else.
I'm facinated with entanglement, weak and strong nuclear force, Bells inequality and Aspects experiments. Heisenberg uncertainty and Pauli's exclusion principle are just a few of the things that it's hard to believe humans have evolved to a point that we can actually understand these things. |

Fascinated by all this.
Did you know, all the gold on earth was formed in a split second during the formation of the earth, at billions of degree's C.
No new gold has ever or will ever, be formed again.
The gold on your fingers is 6.4 billion years old. |

I have a bit more reading to do Things have moved on a lot in the last few years. Chaos is a dramatic telling of the story. To get to grips with the principles, and indeed detail, wiki is better imo. |

Not quite. The earth took quite a while to acrete from the remains of some massive astronomical event; gold is formed frequently during these events. I've just been reading about about a neutron star collision in 2017 which is believed to have formed between 3 and 20 earth masses of gold.
Gold has also been produced on earth quite a few times by nuclear physicists. It's extremely unlikely any of that will be found on your finger though. |
