Please stop posting messages on my talkpage telling where these are, you will not be the first. It is a JOKE (but not very funny now I've had to explain it), if I really want to know I can just follow the wikilinks in the boxes.

My specialisation on Wikipedia is rapidly becoming 1920s electronic filter designs and designers. I know, this is sadly narrow and it is also not what I had set out to do on Wikipedia. Quite by accident, I discovered that there were virtually no articles in this field and co-incidentally, I happened to know a great deal on the subject. It seems that for every article I write, another three are suggested by the process of writing. Perhaps there will be an end to it one day, but at the moment it looks like it will go on forever. For variety, however, I also write articles on sequential move puzzles (and virtually anything else that takes my fancy).
Spinningspark is an electronics engineer working in the communications field. His interests include;
Especially the Roman and post-Roman periods and the early formation of European nations.
Spinningspark is interested in the hard sciences, especially theoretical physics and the philosophy of science. Spinningspark takes part in the Search for Extra Terrestial Intelligence (SETI@Home) distributed computing project. If you wish to take part in this project you can go to the SETI@Home homepage here . If you would like to see my results from this project then go here .
Spinningspark is interested in all kinds of mathematics. He is currently active in several projects searching for new prime numbers. Amongst these is the search for new Mersenne primes. The Great Internet Mersenne Prime Search (GIMPS) is a distributed computing project which anyone with an internet connection can take part in. If you wish to take part in this project you can go to the GIMPS homepage here .
Games and Puzzles
Spinningspark loves puzzles of a mathematical or logical nature. Spinningspark hates puzzles that rely on a linguistic pun or other kind of "cheat" to make them work. Spinningspark is a speed solver of Rubiks cube and had written computer programs to solve the cube. Never managed to get the computer to solve as efficiently as a human though. Spinningspark has a large collection of Rubiks puzzles of many shapes and geometries.
Spinningspark likes to ice skate (artistic, not hockey) and has skated competitively.
Spinningspark also occasionally contributes to aeronautical articles. He holds a Private Pilots Licence (PPL) but is probably in the top 100 most incompetent pilots in the UK, if not the world. US readers will be delighted to learn that he no longer does any flying in that country.
I will not tread your dusty path and flat,
denoting this and that by this and that,
your world immutable wherein no part,
the little maker has with maker's art.
I bow not yet before the Iron Crown,
nor cast my own small golden sceptre down.
Some editors will put articles on their lists to which they have merely made a small contribution. All the articles and images shown here and on the linked lists have been created by me from scratch, or at most from an insignificant stub.
Zobel invented the m-derived filter and the constant-resistance filter, which remains in use today. With Carson he helped to establish the nature of noise in electric circuits, concluding that—contrary to mainstream belief—it is not even theoretically possible to filter out noise entirely and that noise will always be a limiting factor in what it is possible to transmit. Thus, they anticipated the later work of Claude Shannon, who showed how the theoretical information rate of a channel is related to the noise of the channel.
Analogue filters have played an important part in the development of electronics. Especially in the field of telecommunications, filters have been of crucial importance in a number of technological breakthroughs and have been the source of enormous profits for telecommunications companies. It should come as no surprise, therefore, that the early development of filters was intimately connected with transmission lines. Transmission line theory gave rise to filter theory, which initially took a very similar form, and the main application of filters was for use on telecommunication transmission lines. However, the arrival of network synthesis techniques greatly enhanced the degree of control of the designer.

Zobel networks are a type of filter section based on the image impedance design principle. They are named after Otto Zobel of Bell Labs who published a much referenced paper on image filters in 1923. The distinguishing feature of Zobel networks is that the input impedance is fixed in the design independently of the transfer function. This characteristic is achieved at the expense of a much higher component count compared to other types of filter sections.
Zobel networks were formerly widely used in telecommunications to flatten and widen the frequency response of copper land lines, producing a higher quality line from one originally intended for ordinary telephone use. However, as analogue technology has given way to digital they are now little used.
Minimum orbit intersection distance, abbreviated MOID, is a measure used in astronomy to assess collision risk between astronomical objects. It is defined as the distance between the closest points of the osculating orbits of the two bodies in question. Of greatest interest is the risk of a collision with Earth; the MOID between an object and Earth is called Earth MOID. Earth MOID is often listed on comet and asteroid databases such as the Jet Propulsion Laboratory's Small-body Database. However, MOID can be defined with respect to other bodies as well: Jupiter MOID, Venus MOID and so on.
An object is classified as a Potentially Hazardous Object (PHO) – that is, posing a possible risk to Earth – if, among other conditions, its Earth MOID is less than 0.05 AU.
The components of a mechanical filter are all directly analogous to the various elements of an electrical circuit. It is therefore possible use electrical network analysis and filter design techniques on mechanical filters which is a great convenience for electrical engineers in the design of these circuits. Any of the classic frequency responses can be obtained with the right choice of component values.
A Murphy drip is a rectal infusion apparatus to administer the medical procedure of proctoclysis, also known as rectoclysis. During the procedure, an end of the Murphy drip is inserted into the rectum and large quantities of liquid are infused into the rectum drop-by-drop. Prior to fluids or medicines being given intravenously, the Murphy drip and hypodermoclysis were the prime routes to administer fluids such as for replacement when patients could not be fed by mouth. Wisconsin surgeon John Benjamin Murphy introduced the drip method of saline infusion per rectum in the treatment of peritonitis.
