Sadao Adachi rest on the upper surface of leaves, and can easily be found from above. However, hangingflies usually hang themselves on the edge of leaves or twigs, and catching them usually requires a lower observing point of view. Some species prefer to be active among the deep shadowed twigs and leaves (Wang

Alexey Khokhlov,Rustem Valiullin the use of infinitesimals as valuable tools that are once again respectable in mathematics. Infinitesimals have been around for over 2 000 years and generally had a bad press. Their use has at times been free and viewed as a blessing (throughout the eighteenth century, for example), and at others v

Leigh Canhamimal geometry. Some of the results confirm what one intuitively might expect to hold when elements are allowed to be infinitesimal. In what follows, the formalization of various notions found in Newton’s prose is examined. Important theorems about motion along arcs, circular paths and elliptical orb

Brahim Bessaïs Feynman integration is very hard so quantum field theorists have become very skilled at extracting every bit of information they can from the structure of the graphs as well as having many more analytic tricks.
