I started out studying math, physics and chemistry.  Later I moved into 
biochemistry including the Human Genome Program in the U.S.  The 
controlling factor in all of this was good teachers and mentors.  
Basically I followed the path of fun problems and good people. 

Now I am trying to produce very rapid sensitive instruments, some of 
which detect biological molecules.

For my daughter, who is in seventh grade, and her friends, I try to teach 
science not as a series of dry topics but as intriguing puzzles to be 
figured out.

We have done:
What happens when you leave bread in a glass of water?
How can you make an image of a flying plane and background on a computer 
Why do peppers 'taste' hot?
What is critical in getting a car engine to work efficiently?
When cows were imported to Australia, what was the ecological mistake and
how did dung beetles help?
How smart are ants really?  Can they tell where they are going?
What part of card tricks is trickery and what part is statistics?

With the why do peppers tast hot puzzle, my daughter and her friend 
assumed that taste buds sensed the 'hot taste.'  I asked how they tested 
this hypothesis.  They started doing experiments to see whether you could 
'taste' hot where there were no taste buds.  Rapidly, they found out that 
'hot' is sensed by pain receptors (they even found a study on the WWW in 
which topical pain killers block the hot taste) and not by taste buds.  
You can taste hot on the back of your hand.

In each of these, we concentrate on understanding the problem and then on 
solving it in a clear logical way that will withstand questioning by 
others.  To me this clear understanding of the problem and its solution 
is critical whether the problem is in biology, chemistry, math or 
interpersonal relations.  

Many confusions, especially in rapidly developing fields such as parts of 
biology, have come from an incomplete understanding of the problem or its 
solution on the part of the people who are talking about it.

Basically, we have fun while we figure out how the world works.  Much of 
math and physics shows up in these puzzles not as dry things to learn but 
as shorthand ways to remember what we found out and to predict the 
answers to other puzzles.

I would appreciate any comments on this approach.  Suggestions, 
criticisms, even outright laughter would be fine.

In the mean time, she and I are trying to learn more about what happens 
to eyes as you get older.  We hope that some of the changes are 
reversible.  We are having a good time.
