How did you find PF?

DuckDuckGo search.

New member introduction.

My name is Graeme Mace.
I was born and live in Berkshire England.
Born in 1960, I qualified as a Vehicle Mechanic in 1979 from Reading Technical College, and have stayed in the Motor Trade ever since.

I have always been interested in Engineering, Physics and Astro physics, reading books by Stephen Hawking and Prof Brian Cox etc.

My latest book ` Relativity The Special and the General Theory` by Albert Einstein, has re-lit the fire in my head on subjects I was taught in school, but some how managed to store in the wrong retrievable memory bank in my brain.

I found you guys by wanting to confirm my understanding of the Parabolic curve of a falling stone dropped from a moving train, something I was shown 50 years ago !

My brain will never stop keeping me awake at night ?

I hope I am typing this in the wright place as a new member.

Kind regards

Graeme Mace

Welcome to PF, Graeme. It's good to have you here.

In addition to the main PF forums, be sure to click into the "Insights Blog" link at the top of the page. There are many helpful articles there written by knowledgeable PF members, including many on Relativity.

Enjoy PF!

One man's (or woman's) parabola is another man's plumbline!

One man's (or woman's) parabola

Haha. I was going to say ACKtually it's a highly eccentric ellipse that happens to intersect the Earth's surface.
