Unlock the science behind the secrets of the universe

If you’ve ever stared up at the night sky, wondering how it all works, you are among millions across mankind’s history who have been inspired to learn more. But many are put off because they assume the science that makes the stars move across the heavens and powers the rockets we send out beyond the Earth is too complex for them ever to understand.

It doesn’t have to be that way.

Writer and space enthusiast JD Palmer is on a mission to demystify the secrets of space science. He believes that astronautics, Special Relativity and other theories that explain the universe are built on core ideas that anyone can understand with a bit of dedication – and the help of someone to lead them through the basic maths in easy steps.

His first book, Light Needs Time, explains how Einstein’s Special Theory of Relativity affects the very fabric of the universe we live in. His new title, The Soft Landing Challenge, is the second of a series of three that will demonstrate the mathematics behind space flight.

Packed with charts, diagrams and examples, these books make the complex understandable and take Special Relativity and rocket science out of the lecture theatre and into your home.

Excellent book - highly recommended

A really excellent book on a fascinating topic. This book takes the reader through an easy to understand, but very enjoyable journey into Einstein’s Special Theory of Relativity. There are some brilliant diagrams and illustrations that help the reader to make sense of what could otherwise be a confusing subject. Highly recommended for anyone who would like to understand more about Relativity.

The Soft Landing Challenge

Modelling a Rocket’s soft landing from orbit in a spreadsheet

ISBN: 1075401240 - Buy on Amazon

You may be interested in Rocket Science but…

…can you guide a Rocket to a soft landing from orbit?

Using only Newton’s laws of motion, his law of gravity and some basic mathematics this book demonstrates that the flight of a Rocket from orbit down to a landing on the surface of a planet can be realistically modelled in a simple spreadsheet.

You may be interested in Rocket Science but…

…can you guide a Rocket into orbit?

Fortunately, Sir Isaac Newton prepared the way for us hundreds of years ago in his laws of motion and law of gravity.

Using only Newton’s four laws and some basic mathematics this book demonstrates that the flight of a Rocket to orbit can be realistically modelled in a simple spreadsheet.

Light Needs Time

Making sense of Einstein’s Special Theory of Relativity

JD Palmer

ISBN: 1977932622 - Buy on Amazon

If you want to build up a sound understanding of Einstein’s Special Theory of Relativity by teaching yourself from first principles…

…this is the book for you!

The theory gives us a much richer and deeper perspective on reality than the one our senses provide us with – but don’t let yourself be put off by its daunting reputation. You really don’t need to be a genius like Albert Einstein to understand and marvel at the symmetry and beauty of his work.

Packed with more than 100 diagrams and charts, Light Needs Time guides you step-by-step through a detailed investigation into Einstein’s Special Theory of Relativity.

'Stop-motion' simulation

A basic simulation of an object moving in space can be created from a set of PowerPoint slides. The simulations are enhanced considerably by the addition of a suitable soundtrack.
