whats the story with the links with all the % in it
and do really need all these obvious copy and paste posts by Fermer05 admins?

It is just what happens when you paste a URL link that has special characters. The original URL did not have these % symbols. The original URL had Russian letters. These letters can not be displayed in the text editor of the forum so when you paste the link it converts the Russian characters into URL encoding or also called Percent encoding.

Basically it is limitation of not being able to display the original character set and how it then gets handled.

The trouble is that some of those percent encoded URLs have spaces introduced which I don't know you can't really click on them because they are incomplete. I suppose you could highlight and copy, then paste into browser address bar and then delete extra spaces before activating the link.

It is common to sometimes see percent encoding with a URL even if the character set is not different. This often occurs when the URL is part of a server path that include real spaces. Since a URL can't have spaces then the space is converted into its percent encoding equivalent and that is why you often see %20. A space is ascii character number 32 decimal which corresponds to 20 in hexadecimal, which explains why a space is %20.

Therefore the way it works is that in a URL when a % symbol is seen by the browser it then knows that what follows is a hexadecimal number corresponding to the character for the next place in the URL.

Criticism of the lunar theory of the tides.

According to the Static theory of tides, the lunar tidal wave moves from east to west after the moon, at a speed of 1600 km / h, circling the Earth in 24 hours, filling only the eastern coast of the continents. But through the centuries it was discovered.
1. What does the lunar tidal wave flood both the western, southern and northern shores of the continents?
2. That the tidal wave speed of 1600 km / h is detrimental to both continents and marine fauna?
3. What at the same time, not two tidal humps are functioning all over the globe, but more than a hundred, regardless of the location of the moon?
4. That for some reason abnormally high tides are formed in half-closed bays, where there is no direct access to the tidal wave. And in the bays open to the tidal wave, are there no tides at all, or are they small?

Later, a dynamic theory of tides was proposed, which was supposed to answer all the questions posed.
According to the Dynamic Tidal Theory, a lunar tidal wave travels at a speed of 1600 km / h. Crashing into continents, islands and shoals, a tidal wave slows down and breaks up into numerous secondary tidal waves.
Then, under the influence of interference and the Coriolis force, secondary tidal waves begin to rotate, due to which ebbs and flows are formed.
Amphidromic point
Dynamic Theory
The movement pattern of the secondary tidal wave, from the North Atlantic to the White Sea.

But the dynamic theory of tides does not answer all the questions posed.
1. The assertion that due to interference tidal waves begin to rotate around islands and shallows is doubtful.
2. The claim that “secondary tidal waves” move against the movement of the moon from west to east is also questionable.
Coriolis force is too weak to deploy tidal waves and tsunamis.
3. According to the dynamic theory of tides, tides are formed only around islands and shoals, and not in the seas and bays.
4. In the atmosphere, the dynamic theory of the tides should work wonders, because the atmosphere is much easier to move than water.
In places where tidal waves collide, something unimaginable must happen.
5. While the tidal wave makes one revolution around the Earth, the Moon makes two turns, how is the gravitational connection between the Moon and the tidal hump?
6. In order for the lunar tidal hump to exist, the inhomogeneity of the gravitational field is necessary, and for this, the moon must always be above the hump, otherwise the hump will fall apart?
7. In the Dynamic theory of tides, the concept of an applied hour is introduced, from 0 to 12 - the time the tidal wave lags behind the moon, due to friction against the bottom of the ocean.
9. If the applied hour is zero, this means that there is no tidal wave friction on the ocean floor, and the wave speed is 1600 km / h, and if the applied hour is 12, this means that the friction reduced the tidal wave speed to 800 km / h.
Why is there a tidal wave friction on the bottom of the ocean in one area and not in another?

No, there is no tide moving faster than the speed of sound.  Friction with the ocean floor limits the speed of a wave, and since a tide is a very long wave, there is no place on the planet where a long wave moves that fast.  It's one reason the actual tides are amphidromic systems, because physics.
