This book is concerned with two tightly knit topics - those of mathematics and astronomy. Its focus is primarily concerned with planetary astronomy, and specifically the history of accounting for the spacing of planetary orbits. The story begins with the ancient Greek philosophers and continues to the modern era and the new data being gleaned from the study of exoplanetary systems. Throughout the text, the manner in which mathematical theory has been used to decipher, and impose order upon the solar system, will be examined. Attention and discussion will be directed towards the so-called Titius-Bode rule, a long-standing ordering principle, that in fact it has no physical underpinning or explanation.

 

The story presented will look at how humanity has learned about the workings of the solar system, and it will look at the philosophical problems that arise when mathematical exposition leads observation. Furthermore, the fundamental role of mathematics in the development of physical theory is examined, and it is argued that there are some gaps in our knowledge of the solar system (and the universe) that mathematics and physical theory will never successfully bridge. The text will present material at the informed-amateur scientist, university undergraduate student level.

The best dog ball EVER!!!
Our 3 y.o. Mini Australian shepherd destroys every toy that she can. We can’t have any kind of cloth toys, including the heavy duty, triple stitched, fire hose Kong toys. We can’t have rope toys, even the balls. There are many rubber or silicone toys we also can’t have as she destroys them as well. She has 5 of these balls, some for over a year and they are still in GREAT shape. Left in the sun, rain, etc, they just hold up. They also don’t have a lot of surface area to hold slobber so your hand doesn’t get all wet. Heavy enough to still throw a fair distance, but light enough that the dog was fine the few times I’ve accidentally drilled her in the ass. These are the best.

The best dog ball!
I have bought about 8 of these balls now. Mostly because my dog looses his or I’m buying them for my other dog friends. I put a dog bone in it at dinner time and it keeps my dog occupied while I’m eating my dinner. He loves it and so do I! They also have different sizes. We recently got a bigger dog breed so I got the biggest one. He loves it as well! Worth every penny!

Dog loves them
I have these balls in every size they come in. My dog loves them and they are the only thing that he can’t destroy. I also have put a squeaker from a destroyed toy inside of one (it was a difficult thing to do) and made my own indestructible squeaky ball as well as putting a small sized ball inside a medium sized ball to make something that he plays with on his own for hours. Even if you just use it as a ball without any of the modifications I have done I highly recommend this product. You can play with your dog indoors and not be too concerned about damaging anything. It also is great for playing in the snow since it doesn’t sink as far as other balls.

Great for small dogs
This ball lasted 5 minutes for my bully. That's my fault for not reading that it was small. I'm going to look for the largest size in hopes to get a few more minutes worth of chomps. My dog loved it.
