Just an old guy (60+) who found he has forgotten more than a lot of people ever learnd, and wants to try to get some of it back.

I've been helping my granddaughter with geometry (High School) and had no problem getting up to speed, but I realized I don't remember a great deal of what I learned in college.

I bought a copy of Network Analysis by Valkenberg to try to refresh my skills.

It looks like there are many helpful people here, and lots of resource material.

welcome to the forum!!!

Here lies the reader who will never open this book. He is forever dead.

Taking a new step, uttering a new word, is what people fear most. ― Fyodor Dostoyevsky, Crime and Punishment

The knowledge of some things as a function of age is a delta function.

Yes, I do. The brain does not age as the body does. It can suffer illness but it does not wear out.

Hi TheGimp,

It is no good to try to stop knowledge from going forward. Ignorance is never better than knowledge - Enrico Fermi.

Nothing is better than reading and gaining more and more knowledge - Stephen William Hawking.
