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.

UAPs, Formerly UFOs, If They Are Real How Can We Explain Their Arrival to Earth?
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 ...

Overcoming Difficulties Encountered with Mathematics
Thank you for your comment in answer to my previous observation and question.
The introductory section advises us, in its second paragraph, that "The placement test for algebra was the first one given, and if a student passed it additional ...

Aurora Can Disrupt Electrical Devices And Even the Grid?
Thank you for your comment in answer to my previous observation and question.
Does auroral activity damage or do in the electronic devices in astronaut/cosmonaut suits during space walks or space-station exterior repairs?

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 -- ...

Polar Coordinate System
Thank you for your comment in answer to my previous observation and question.
The fifth subheading, Polar graphs, contains, with its information about limaçons, the statement that "If the magnitude of a is between the magnitude of b and of 2b ...

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 ...

A number oxsaxon aristocrats kept hold of personal wealth and land, for a while, if they did not fight for Harold. But it was a shor5 term measure, eventually they inte4rmar8ed with the saxonxs

Yes, but math skills imply one has developed logic. I do not consider rote learning of math processes as worthwhile. Students should always ask why, and building on understanding.

Aurorae can by electrical induction.

UAPs, Formerly UFOs, If They Are Real How Can We Explain Their Arrival to Earth?
G0 to YouTube and look at Mike Brown of Cal Tech. He has some insights. The world awaits visual confirmation, to prove it is not a cluster of small objects altering orbits of Keiper Belt objects. Best guess is it would be something like ...

Polar Coordinate System
Since there is no need it could run into opposition. Scientific article space is inadequate, so something less significant could find difficulty in being included.
