Mathematicians have decided to task on the oars

Mathematicians have found another solution funny, that is: how to arrange the oars on board the boat, so that while sailing in it do not raise cross-point, ie, the boat went smoothly and did not hesitate. Article scientists have not yet accepted for publication, but its preprint available at arxiv.org.

As part of scientists interested in the issue of athletes in the seating of eight - a boat in rowing, which sit eight oar and steering. Each rower in one oar that is that it can accommodate the left or right side. This eight to go much better if the rowing (it is believed that oar exercise movements simultaneously) is not exploring movement perpendicular oscillations (in this case say that the transversality time zero).

This natural seating (ie the first oar left in the second case, and so on) that alternates be used up to 50 years of shloho century turns bad - transversal moment is not equal to zero. For chetvirok in 1956, the Italians invented the following solution: the first and fourth paddles on the left, and two others - the right. "Skleyivshy" two fours, you can get seating for the team of eight people.

Math managed to find seating, similar to the Quartet, which so far has not been known in professional sports. This is the seating arranged quite simply - the Italian version of each oar must be replaced by two. That is, in first, second, seventh and eighth left the oars, and in the past - right.

In addition to the work managed to show that in addition seating, two glued together with Italian chetvirok and another one (the so-called German), no other possible locations of the eight athletes in the boat can not be.
