Temporally Lower...

Preface:

Common Sense, Perception, Reality and Physics had all gone down to the pub for a drink or several. OK, quite a few severals. Afterwards they went for a curry and met up with Theology and Philosophy who had earlier been to see a play starring Space, Time, Light speed, Quantum Mechanics and an old school friend called Relativity. They all got hopelessly drunk and wound up feeding Carlsburg the probability cat a large dollop of "what if" flavoured meaty-chunks.

In this witty and quite possibly intelligent (although probably not) look at the many and beautiful issues which surround time travel, both Richard Branson and G.N.E.R. come in for some serious temporal poundings but the desert trolley of humour is always at hand – along with an aspirin and a glass of water.
This book quite possibly has the ultimate answer to the not-quite-ultimate question "Where can I buy a tuppence-ha'pney time machine, and how much are they at ASDA".

It almost certainly does not have any sort of detailed biography of Albert Einstein (Ol' Albo), Max Planck (Thick-as-two), Erwin Schrödinger (The Crackpot Cat Cracker), H.G.Wells (Ol' Herb), William (Billy Wobbleshaft) Shakespeare, Patrick (The Monocle) Moore, Carl Sagan (The Pudding Guy), Steven (A Brief History Of Sounding Like A Cool Robot) Hawking, or Richard (I'm a pickle, put me in a sandwich) Branson whose names are casually dropped like orange blossom upon frozen water within sight of Mount Kilimanjaro – mainly to impress, partly to inform, but occasionally just to test the spell checker.

It is highly conceivable that, in between the easy presentation of serious physics and even less serious philosophy, seriously serious ideas are put forward.

H.G. Wells's novel "The Time Machine" thrust the concept of time travel into the public's imagination and offered plausible technical discussion within the story.
Steven Hawking's "A Brief History Of Time" brought modern cosmology to the masses and threw in more than a few hints of philosophy.

"The Theory & Practice Of Time Travel" takes that mass and the hints along with the concepts, adds flour, sugar, egg-yolk, curry-powder, then bakes them at gas mark 5 into a delicious temporal-cosmological-philosophy cake that should only be served with a nice cup of tea – and a health warning.

And it makes a damn good door-stop.
