We live in a wonderfully complex universe, and we are curious about it by nature.  Time and again we have wondered - why are we here? Where did we and the world come from? What is the world made of?

If the universe started with the Big Bang, what was the 'nothing' that existed before it?  Can you get 'something from nothing'?  Is that what thought is?  Does quantum theory hold the key?  Does your head hurt just thinking about this stuff...?

Even if you can't understand the maths, you can still enjoy the pretty pictures says Phil Becque.

Check out one of the seminal moments in physics, writes Phil Becque

 

There is a paradox at the heart of quantum mechanics; namely, that the observer - in this case very sensitive measuring equipment - can affect the result of an observation, before the photons or electrons have been activated.

Looks like Julia might have a point about the dangers of WiFi, says Phil Becque. 

 

Just when you thought it was safe to become a planet-hopping space cadet, it turns out that electrons (of all things) pose a real danger in the radiation belts that surround planet Earth.   

In case you didn't know, electrons are the subatomic particles, that, when suitably directed, make every modern gizmo work - from iPods & iPhones to washing machines and high-speed trains. If you are a jobbing electronics engineer like me, to be told they might be dangerous is like being told that your well-trained, perfectly behaved pet chihuahua has morphed into gigantic white shark, with the appetite of a killer whale!

The next time you have to raise your umbrella against blustery April showers, spare a thought for folks in the US, who have to deal with the effects of a remote weather phenomenon that many may know by name as El Niño, but whose influence has only recently been understood.

 

Siegfried Schubert and his colleagues at NASA's Goddard Space Flight Center are studying the impact that El Niño-Southern Oscillation (ENSO) events have on the most intense US winter storms.

OK, OK it's possible there are more than 13 things that don't make sense to you and me, says Michael Brooks.

 

But for scientists who believe that there is a rational explanation for pretty much everything, it's more than a little embarrasing to have to own up to this list.  Of course science is really just a collection of theories with some experimental data to back the ideas up so it should come as no great surprise to that there are 13 things that don't have a very good explanation. It would be 13, wouldn't it?
