A new phone app that measures how much you time travel

Time Warper is a new app for iPhones and Androids that takes your GPS signal and calculates how much your time has slowed down, both due to Earth's gravity and due to your motion, according to Einstein's theories of relativity, compared with a hypothetical clock floating far from earth in space. You can use it to see how quickly or slowly you are ageing relative to other people using the app.  If I get the time I might write a blog on the physics that goes into it.

I helped develop it with University of Surrey computing students and Matt Casey at Pervasive Intelligence Ltd.

It has been developed for a new feature length documentary I am filming for BBC4 on gravity, which will air in the New Year. The more people download and use the app, the better and more accurately will be able to create a gravity map of the UK.

Aliens: Science Asks Is Anyone Out There?  

It's the biggest question we've ever faced, one that has fascinated generations of humans: do aliens exist? If they did, what would they look like? How would they think? And what would it mean for us if we found them?  Here, Professor Jim Al-Khalili blasts off in search of answers.

Featuring twenty pieces by top scientists and experts in the field including Martin Rees, Paul Davies, Monica Grady, Seth Shostak, Ian Stewart and Adam Rutherford, Aliens covers every aspect of the subject

Available in paperback and on Kindle

The Life Scientific

Current series resumes on 15 November with Professor Lynne Boddy

Each week, Professor Jim Al-Khalili invites a leading scientist to tell us about their life and work. He’ll talk to Nobel laureates as well as the next generation of beautiful minds to find out what inspires and motivates them and what their discoveries might do for us.

Jim Al Khalili's Ted Talk

(1.3m views so far)

How does a robin know to fly south? The answer might be weirder than you think: Quantum physics may be involved. Jim Al-Khalili describes the new and extremely strange world of quantum biology, where something Einstein once called “spooky action at a distance” helps birds navigate, and quantum effects might explain the origin of life itself.
