A small technical collaboration group looking at some long-standing unresolved physical problems.


Tushino Ltd was originally just a device for keeping earnings from side jobs neatly labelled for the tax man.

It evolved into something a little more complicated when the Avian Navigation Methods Project got under way. Then we started doing technical checking for a particular organisation. Tushino just expanded a little. It is now a group of people around retiring age who like poking about inside difficult looking engineering and science projects.

Tushino is never allowed to get big : Only one or two projects and only a few friends working on each one.


We are still working on a long running project on Avian Navigation Methods (How migrating birds find their way, and how pigeons can home) and we are currently marketing a book describing the new ALFIC system which seems to explain how land based birds find their way. The problem of pelagic birds is still being worked on. Go to Migration Site.

It ocurred to us that many industries have knotty problems that are well known to those in the trade, but which are almost comletely unknown outside. These are the sorts of problem that might very well yield to a fresh eye. We are attempting to to create a list of some of them.

We do not deal with any matters involving quantum theory.


We also maintain an Specialist proofreading service which deals with technical documents and those which were originally written in Russian. For technical documents a lot of attention is paid to the arithmetic and the units.
