Our friends at LiveScience love Garth's stuff so much (*) they threw out the idea for a nifty widget that will give you a little drop-down tool and let you see lots of his equations.

So if you are unsure whether or not to bluff in Texas Hold 'Em, simply stop the game, pull out your iPhone, and plug in the numbers.

Likewise if you are standing in line at Starbucks and unsure how many cups of coffee you should have, this widget can tell you.

Basically, you can completely abdicate responsibility for your own decisions. Leave it to Garth. He knows what he's doing.

(*) We love them too!
