Dramatic Meteorologist

Scott Hetsko uses his whole body to report the weather like he's presenting an exhibit. It's different and... well... funny. :)

Here I captured a shot of him merely talking to the other anchors on the show.

But where he's really expressive is in front of the blue screen. I'll have to capture one of those tomorrow night.

Where was the Internet when I was in 7th grade?

That would've been 1989-1990... I'm guessing it existed as a bunch of unorganized networks for government research and stuff, but that's not the point...

I came across this puzzle in a bunch of old forwarded e-mails and just had to solve it:

Diophantus passed 1/6th of his life in childhood, 1/12th in youth and 1/7th as a bachelor. 5 years after his marriage, there was born a son who died 4 years before his father, at half his father's final age.

How old was Diophantus when he died?

Ok, so this is one of those word problem things. I worked it out by drawing timelines of the father and son and labelling each section with values provided in the problem - either in years, or as fractions of f (the father's age of death) or s (the son's age at death).

This gave me an equation with f on one side (which I wanted to solve for) but a sum of fractions with f in the numerator and uncommon denominators on the right side.

That's pretty much where I got stuck. I couldn't remember what sort of tools I could use to simplify the equations... I tried dividing both sides by f, but I'm not sure if I did it right. Then I tried subtracting a fraction from both sides but again I'm not sure I did it right. I ended up with something that looked like it was going to come out with a negative value so I knew I messed up somewhere.

So I went online looking for an equation solver. Boy oh boy, look what I found!

DiscoverySchool.com's Linear Equation Solver not only solved the equation - it showed me HOW to solve it!

Here is the solution.

That's so cool. :)
