WE HAVE FREE will. You decide who to talk to, what to say and where to buy lunch. It’s obvious, right? Yet certain studies suggest our brains make some decisions before we’re even aware we’ve made them. So are we really in control? Turn to p32 to find out.
It’s hard to make a decision if you think you’re being misled. But if you want to get someone to tell you the truth, what’s the best way to go about it? On p53, Jo Carlowe asks a former CIA operative for some practical tips to use in everyday life. The CIA must surely be grateful for the invention of Kevlar. The fibre, best known for its ability to stop bullets, was developed 50 years ago by Stephanie Kwolek at DuPont. Turn to p42 for the science of body armour and the new technologies that could save lives in future.
Nothing would save you from certain death if you were ever sucked into a black hole. But I’ve often wondered why scientists are so sure they exist when we can’t see them. Top science writer Brian Clegg rounds up the evidence on p86 and reveals the mystery that hasn’t entirely gone away.
And there’s much else besides, including a look at what’s beneath your feet – as featured in an upcoming BBC programme. Enjoy the issue!
