Physics fanatic Cameron McEvoy will inject some “chaos theory” into the pool when Australia tackles the Pan Pacs swimming titles on the Gold Coast.

A member of the now infamous men’s 4x100m freestyle London Olympic squad will inject some “chaos theory” into the Pan Pacific swimming championships on the Gold Coast.

But breathe easy Swimming Australia officials – the only waves London Olympian Cameron McEvoy wants to cause is in the pool at the four-day August meet featuring the mighty US squad.

Physics nerd McEvoy headlines a preliminary 30-strong Pan Pacs squad after taking out the 100m-200m freestyle double at last week’s national titles in Brisbane.

McEvoy said the laws of physics had helped improve his technique in what became a breakout meet for the 19-year-old.

Gone was the quietly spoken junior member of the 4x100m relay team paraded in front of the media to face the music over their controversial pre-London Games bonding session.

Instead the public saw a confident, self assured youngster ready to take on the world again after falling in love with physics 18 months ago and using it to his benefit in the pool.

“Because the systems involved with the water and the body are so complex it goes more into the chaos theory field,” McEvoy said.

“I can get a general idea of what would be better in terms of resistance in the water.

“I can use the theory to play around with and get an approximation of what I need to do and work within that range and tinker with my stroke at training until I find the ultimate – if that makes sense.”

Sort of. And in the gym?

“That is all about classic Newtonion physics,” McEvoy said.

“Swimming is all about power-to-weight ratio and building on that.”

The whippet-like McEvoy must be doing something right.

He won his maiden national title in the 200m then overpowered world champion James Magnussen in the 100m final despite giving away 24kg and 13cm.

And both in times that would have claimed 2013 world titles medals.

But McEvoy reckons he will “never over-think” his swimming.

Then again McEvoy’s idea of having fun is building an alpha particle cloud chamber in his bedroom.

The rest of the Pan Pacs squad will be unveiled after the Glasgow Commonwealth Games.

Anyone who sets an A-qualifying time for their event in Scotland will be picked to take on the US, Canada and Japan at the Pan Pacs from August 21-24.
