### Hello

Hello everyone,

I've got an ambitious long term project: I'd like to be able to understand the maths of GR. Currently, I'm studying limits via the Kahn Academy and various textbooks.

Nice to meet you..

Hi RobinM

Welcome to the forum!

What does GR stand for?

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.

Hi RobinM;

Welcome to the forum.

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
A number by itself is useful, but it is far more useful to know how accurate or certain that number is.
