Orbit Change Of Artificial Satellite
Orbit change of artificial satellite
In order to raise the altitude of an artificial satellite, it is necessary to accelerate it. When the orbital speed increases, the centrifugal force generated by the rotation of the satellite becomes stronger than the gravity of the earth applied to it, then the altitude rises. At this time, a certain amount of energy is returned from the satellite to the vacuum space to reduce the energy debt. Hence the orbital speed decreases and finally drops below the initial speed. The sum of the reduced amount of the momentum energy and the energy required for the acceleration is returned to the vacuum space.
In order to lower the altitude of an artificial satellite, it is necessary to decelerate it. When the orbital speed decreases, the centrifugal force becomes weaker than the gravity, then the altitude drops. At this time, the satellite is given a certain amount of energy from the vacuum space. Hence the orbital speed increases and finally rises above the initial speed. The sum of the increased amount of the momentum energy and the energy released by the deceleration is borrowed from the vacuum space.

This is the Maiden of Llullaillaco, an Incredibly Well-Preserved Child Sacrifice from the Incan Empire around 500 years ago.
The Maiden of Llullaillaco, sacrificed at around the age of 15, was discovered with the other “Children of Llullaillaco” which includes a 6 year old girl and a 7 year old boy.
These mummies are so well preserved due to their position within a tomb atop a mountain within the extremely dry Atacama Desert. They are so well preserved, that their internal organs are intact, individual hairs on the arms can be seen and even one of the heart’s still contains frozen blood.
The deaths of the three children occurred by drugging the children with alcohol and coca, then placing them in the tomb where they eventually died in their sleep. This appears to have been a very well prepared process, as hair samples dictated that the children had extremely rich diets leading up to their deaths. The tombs were also adorned with elaborate dress and trinkets.
The boy however, faced a different death that could’ve indicated struggle or a different burial process. The boy was very tightly bound, and had dislocated hips and ribs and it appears he died under stress as the clothing contains both vomit and blood. Suffocation is the likely cause of his death due to the way he was bound.

I really want to get into math. What book do you recommend reading!
Great question! Here are some fun ones that are still informative and that really opened up my eyes to what math truly is:
How to Solve It by George Polya. This is a classic and the title speaks for itself: it is about how to reason mathematically.
Hyperspace by Michio Kaku. This one is mathy and sciencey. It is very geometrical and shows how our view of geometry has changed throughout history and how it has influenced science. Kaku is my favorite author.
Proof and Refutations by Imre Lakatos. Another classic. This one has to do with how mathematical proof advances our mathematical knowledge, in other words what professional mathematicians do. It is also surprisingly funny.
Other recommendations?
Does time exists?
What is the actual reality of time?
Why does time follows “arrows”?
