The content of Corollary Theorems website is entirely
educational, therefore it is suitable for all categories of visitors
without any age restrictions. Our intention is to help building a better
future for all the people on our Planet, and we believe this may be achieved
only with deep, profound knowledge. Truth is, there is nothing more
important, or more valuable, than true good knowledge is.
All non-fiction books we carry are educational!
Consequently, were the law allows it, their purchasing costs can be deducted form income. [We can certify that your purchase
falls within the "continuing (advanced) personal education" income-tax category to any governmental agency.]
This aspect appears to be a major problem:
Corollary Theorems site is permanently upgraded [and it
never looks quite finished—sorry about this]. Consequently,
you need to use the "Refresh" button of your
[or press (Ctrl+) F5 on your keyboard] on each page, to actually see the current
version of that page. Otherwise, your Browser may display the old
version stored on your PC in "temp" files [and you cannot navigate our site properly, nor can you buy our books—just
some examples; this situation is valid for all websites on the Internet].
Our site is best viewed in
Vivaldi etc. Unfortunately, MS Internet Explorer
6/7/8/9/10 (+Edge) are the "worst offenders" in
correct, standard, HTML protocols. Note that the older versions of MS browsers [and particularly IE Edge/11/9/8/7/6/5/4/3/2] cannot display our decorative
CSS animations/transitions—but this is not a tragedy.
Again, you need to use the "Refresh" button of your Browser program frequently, on each page of ours, in order to see the actual /(most recent) page.
Use Ctrl + mouse wheel to zoom up/down on our pages.
In case our (fairly advanced) decorative CSS animations/transitions are not displayed
properly/correctly on your PC screen, we can help. Please read
