Hi everyone
Well here is the thing,

whenever I turn the tap water on at a little water flow, the water flow degrades slowly by time, after about 1-2 minutes it is dripping and about another 1-2 minutes after it stops completely. (sometimes it takes even less than a minute)

This happens at the taps of both my baths (there are two baths) and at both cold and warm water.

WHY is this happening?


ps.Also I am at the first floor of the building, the taps are working great in other aspects, the cold water comes directly from the water network and the warm water comes from the "water warmer" tank. And there is not any other water flow in the house at the time this happens.

ps2. It is not annoying, neither a problem, there is no reason for me to change this but I am just curious WHY MECHANICALLY is it happening.

I cant seem to find the solution Im looking for.

Its intuitively obvious to me that the solution (one of them) can and should be +3. After all, (−2)³ = −8.

But every route I take, mathematically, either on paper or via calculator, gives me the exact same solution. Its a weird complex value.

Testing it verifies that it is -a- correct solution, as raising −2 to the solution I keep arriving at does yield −8.

How many solutions does log_{−2} (−8) have? Because I cant seem to reach an answer of 3

log_{−2} (−8) =
ln (−8) / ln (−2) =
[ ln (−1) + ln (8) ] / [ ln (−1) + ln (2) ] =
[ π⋅i + ln (8) ] / [ π⋅i + ln (2) ]... this is the solution I keep getting

Or, in polar form
√[ ( ln² 8 + π² ) / ( ln² 2 + π² ) ] ⋅ cis [ arctan (π/ln 8) - arctan (π/ln 2) ]

The absolute value of the above solution is slightly greater than 1, but less than 2. Should not the absolute value be 3 if +3 is also a valid solution?

Why people thought that the earth was squared? if ancient civilizations like Egyptians, Mayans, Aztecs and others knew a tremendous amount of information about the the composition of the universe that even in our era will be hard to investigate, they knew about planets, stars even asteroids and black holes... so if they knew it thousands of years ago, why the medieval civilizations thought that their own planet was rectangular/squared ?

Halfway there you run into a hurricane, break your main mask, your boat sinks and you drift for days on a board. You then land on a deserted island with only the shirt on your back but there's lots of fresh water, coconuts and lots of fruits. The days and nights are heavily overcasted. How do you know if you're above or below the equator with what you have?

The magnitude of the Earth's magnetic field at either pole is approximately 7.99*10^-5 T. Suppose the field fades away, before its next reversal. Scouts, sailors, and conservative politicians around the world join together in a program to replace the field. One plan is to use a current loop around the equator, without relying on magnetization of any materials inside the Earth. Determine the current that would generate such a field if this plan were carried out. Tak the radius of the Earth as R_e = 6.37*10^6 m.
