[P0] neutral; [P1] classic theory; [P2] favouring the inductive approach; [P3] inductive approach.


The generation of the tides.

The tides would be generated thanks to a decrease in the density of the water, following a change in the configuration of the molecule, induced by the movement with respect to the Moon and the Sun (force d), at critical discontinuous values of angular velocity, provided that there are also heat exchanges, consistent with the trend of movement.

This hypothesis - akin to that applied to the fatty acids in seeds, supported by observations and experiments - prompted an analysis on the arguments in support of the current theory on the tides.

To support the hypothesis there are the video recorded at the “natural observatory for the study of the tides”, at Lusenzo, not far from Venice, shown in the previous itinerary 2.3.

In this itinerary, I will compare these conclusions with what is stated in the current theory on the subject of tides.

The first confrontation on the tides.

The first confrontation (in the next page) is between two different tide descriptions, different even if given by two groups, both in favour of the current theory on the tides.

Theory of the first group (P1).

Those in the first group start assuming a supposed cause, the attraction exerted on the water of the oceans. Then, they outline how the tides should work, on the basis of that assumption, without much attention to how they behave in reality.

Their explanation comes to be at odds with several facts, four of them of crucial importance. Eventually they either put forth some propositions ad hoc, or are forced to make an appeal to our indulgence, given the objective complexity of the matter.

Attitude of the second group (P2).

Those in the second group limit themselves to the data on the behaviour of the tides, leaving the theory on the background, so avoiding to lay bare some of its discrepancies.

Among the second group, I want to mention the NASA\ PO.DAAC., which have helped me a lot in my research, with their video on the tides, as seen from above of their basins.

I want to mention also the sailors, practical people, who have always had the need to establish the times of easy access to a specific port.

Once the current theory of the tides has emerged, the sailors limited themselves to take note, almost in silence, of the differences between practice and theory, as far as the times of high tides, and the times of the passage of the Moon on the meridian.

Without much fuss, they established the “lunitidal intervals”, so implicitly denyng the theory of the sublunar points, and the whole theoretical framework as well.

Following an inductive approach (P3).

The second group has become the best ally in this analysis, developed for the most part on an inductive approach, and presented as an hypothesis during the itinerary 2.3. Without their data, this study would have been much more difficult.

The data, supplied by the second group, the data gatherers, are compatible with the mechanism of the tides proposed in the itinerary 2.6.

The rest of the itinerary 2.4.

On pages 3 and 4: the formula valid in the case of the tides, different from that of gravity, and the ratio of the forces.

On pages 5 and 6: the number of the tidal waves, and the space units of the tides.

On pages 7 and 8: two peculiarities of the tides, not compatible with the current theory of the tides.
