Polar Coordinate System
Thank you for your comment below in answer to my previous observation and question.
It's interesting that a dip and a dent initiate the term dimple even as that last term is the most attention-getting and positive of the three descriptions, ...

UAPs, Formerly UFOs, If They Are Real How Can We Explain Their Arrival to Earth?
Yes, we have several smaller objects already known. The problem is looking for something in space. It is vast. Most things are found along the plane of the solar system, but the disturbance this time indicates the possible object is not in ...

Aurora Can Disrupt Electrical Devices And Even the Grid?
The sun ejects high speed charged particles. while electrical induction is the cause of damage to electronics, the particles themselves are dangerous. This is sike radioactive decay emitting high speed particles. and even transpolar flights ...

Multivariable Calculus: Gradient, Divergence, and Curl
Since we are experiencing an occurrence that repeats, but was last observed before recorded history, and even humans, we can only conjecture from what we have determined. The periodic change was discovered by seafloor spreading as plates ...

Polar Coordinate System
A curve curves inward, then back outward. Imagine a projection of an apple cut in half. Trace the outline, and the top shows a dip. The curve seems to be dented.

Thank you for your comment in answer to my previous observation and question.
Your answer alerts us to "visual confirmation" of something planetary as opposed to something Kuyper Belt-like.
Is the current technology sufficiently strong for ...

Multivariable Calculus: Gradient, Divergence, and Curl
Thank you for your comment in answer to my previous observation and question.
Your answer advises us that magnetic-field reversal perhaps arises in "about 1000 years, but recent observations indicate maybe sooner."
Do we know about how much -- ...

TheThousand Year Garden
The next-last sentence in the last subheading, Conclusion, alerts us that "beautiful places are oft threatened by capitalists endeavouring to turn them into car parks."
Are such changes as beautiful garden to car park arising because of the ...
