# People With Too Much Free Time

## Puzzle 3

Christopher Oliver got this one as well as the first two. His method for the first one gave me a headache... What the heck is congruency mod 4?

Several other people have gotten this, including Adrian, Nikki, Jen, Barb, Christine and Tom Roland of the Tuesday Lab Group of Cell Biology, University of Notre Dame. What I want to know is what the heck are they doing solving puzzles in Lab? Update: They claim they have to do something "while running a gel". I don't even want to know...

Mark Solis had a nice methodical, step-by-step solution to this one.

## Puzzle 2

Mike Petrucelli was the first to get this one!

Several other people have gotten this, including Adrian, Nikki, Jen, Barb, and Christine of the Tuesday Lab Group of Cell Biology, University of Notre Dame. See above...

Mark Solis got this one by using, and I quote:

```SOLIS'S SECOND LAW FOR
SOLVING BRAIN TEASERS:

Work right-to-left, NOT left-to-right.
```

## Puzzle 1

Congratulations to Chris Darrow! He has a real job, though, so has lots of time to waste on this kind of thing. We students have more important things to do. Like bike, ski, roller-blade, etc...

My mom and dad finally got it...

```

Some people from the UK got it...

Kevin,

Yes, please do add us to the list of People With Too Much Free
Time.  But don't mention how much free time we actually used.
We're supposed to be working here.  :)
