| ;The reason is obvious and simple - every single edit of mine has been reverted because they are failures. There is just no point in me editing - as I always have and always will inevitably create work for other knowledgeable and good-faith editors clearing up my mistakes, and explaining on the talk page. This will NOT improve wikipedia - will it? I only reduce its quality. If WP is still around, maybe I'll come back in a few years when I know far more maths and physics and can contribute correctly, but definitley not for now... | |||

| On 25/05/2012 - I effectivley finished the 2nd year of a theoretical physics and applied maths degree programme ("sophomore" - they say in the USA), and about to proceed to the 3rd year. The only tranquillity I have is in the thought of physics and mathematics, and in particular: equations. In all other activities, I think/feel of nothing: zero emotion, just do the task so that soon I can return my head to the thought of physics + maths. I am not normal: though perhaps pseudo-autistic (I possess all characteristics, except for ''any'' intelligence). | |||

Revision as of 00:39, 15 August 2012
I did not name this account after the place Maschen in Germany, Harburg: it was sheer coincidence to combine "Machine" into a "name-like" term.

Background/introduction
Undergraduate in physics, 2nd/3rd year.
- I started on WP on 15 July 2010, then left WP temporarily from 25 May 2012 to 14 August 2012; with the intension to not return for a few years until after I gain a master’s degree in physics, due to my many previously useless contributions...
I couldn't resist:
- there are still things to improve on WP, even without overhaul-rewrites or just those intelligent tweaks for clarity.
- I would like to redeem my pathetic history and become (slowly but surely) a driving force (at least slightly) for improving maths and physics (maybe chemistry) articles; either directly if context is within my knowledge scope or indirectly by questioning the scope and content of the articles, or whatever. Yes there are plenty of people who do this already - would one more hurt?...
- Furthermore, with plentiful appreciation, due to these points of good-faith encouragement independent of my abilities...
- For those that once knew me
- I am not the same backwards-numpty-hyperactive-knuckleheaded-(18/19 year old) teenager anymore... (nor an expert either)...
Likes/dislikes
I like
- logic, symmetry, duality, and self-similarity underlying fundamental principles of any form of knowledge,
- maths, physics, chemistry, engineering and technology,
- emo/heavy metal/J-rock music (the very unfortunately late legend Micheal Jackson is my only exception to "pop" music),
- chess, card games, juggling, jigsaw puzzles/3d (or multidimensional! ) puzzles,
- and in plenty: drawing.
- Slightly prefer the city to the country.
Drawing and diagramming everything; so that information and meaning is actually transferred to a reader as directly and simply as possible, happens to be my obsession. Ironically I'm not very good at it, usually due to my sore misunderstanding of the concept to draw/diagram...
Drawing for recreation (for instance mathematical patterns, technical drawings, people in Japanese manga style, building architecture, and when a kid: almost every form of European train, and so on...) is also very fun, although I can do technical graphics I'm not good at artistic at all! (much of these creations end up in the bin or deleted instead of storage for later leisure!!)...
IMO There is nothing like drawing: simply a pencil on paper allows one to literally release imagination pictorially in no other precise (or vague/mysterious) way, and can be viewed later any number of times to think and rethink the concept of the image endlessly. Of course there is immense diversity of drawing tools and materials mechanically and electronically for any purpose required, to amplify the power of the pencil and paper...
I do not like:
- meat, religon, jewelry, nudity, sex-obsessive behaviour, death-torture,
- the practices/ideology of Nazis, totalitarianism, Saw (film) and its worse sequels... Seven (film), and A Clockwork Orange (film).
IMO it's all horrible, and the mentioned films (of those types) are very negative, disturbing, and encourage disastrously wrong behaviour and ideas for people to copy...
I'm not an animal person: they not are for our entertainment.

Gravitomagnetism - Gravitomagnetic field due to angular momentum. (L = angular momentum and H = gravitomagnetic field strength).
Electromagnetism - Magnetic field due to a dipole moment...
...or equivalently current, same field profile, and field generation due to rotation. (B = magnetic induction field, I = current, m = magnetic dipole moment).
Fluid mechanics - Rotational fluid drag of a solid sphere immersed in fluid, analogous directions and senses of rotation as magnetism, analogous interaction to frame dragging for the gravitomagnetic interaction.Physical analogues of fields
Wave-particle with a measurable wavelength λ has momentum p, wave-vector k and energy E. The uncertainty in momentum Δp or energy ΔE is small. The uncertainty in position Δx or time Δt are both large.
Reverse of the previous situation—if λ is unknown, so are p, k, and E, but ψ is clearer in x and t. So this time Δx or Δt is smaller than Δp or ΔE.Wavefunctions corresponding to quantum particles. The colour opacity (%) of the particles corresponds to the probability density of finding the particle at the points on the x-axis.
Top: frame F' moves at velocity v along the x-axis of frame F.
Bottom: frame F moves at velocity −v along the x'-axis of frame F'.
