Nature is Full of Sticky Problems

Anyone who’s washed dishes knows that eggs stick to pans.  Egg white is mainly made up of water, and a water soluble protein called albumin.  As the egg is heated, a familiar popping sound occurs, as water comes off rapidly as steam. When albumin loses water, it coagulates and works into the many minute crevices…

Let It Snow!

Snow provides more than winter fun.  It supplies a measured supply of water to underground water reserves as it slowly melts and percolates down to the water table.  In contrast, rain water is often carried away quickly as surface runoff along with an accompanying soil erosion. Falling snow also purifies the air.  Every snow flake…

As a parent I always told my kids that loud rock music would damage their hearing.  But as a scientist I was on flimsy ground. I ignored experiments that compared hearing loss in people who regularly attended rock concerts with control groups who didn’t listen to this kind of loud music.  An insignificant hearing loss…

Edible Explosives

Before my life-transforming heart by-pass operation, I controlled angina pain by taking tablets containing nitroglycerine. Since this is a highly explosive substance, one of my friends speculated that I might be banned from flying if I got too close to the sniffer dogs at the airport! Nitroglycerine is so easy to detonate that it wasn’t…

PRESUPPOSITIONS OF SCIENCE

Many well known scientists believe that the realm of the physical universe is all that exists. This universe consists of matter (the “material stuff’ that we can know by our senses) and forces (such as gravity and electrical forces). In essence, they believe in nature alone. They seek to know how forces act upon matter….

Hard Bread And Soft Cookies

One evening we neglected to do the usual kitchen clean-up.  I discovered in the morning that although a bread stick had become so hard I could use it as a hammer, our cookies had become soft and unappetizing. Cookies and bread differ in both composition and texture.  Cookies are denser, and contain much more sugar…

Water, The Miracle Molecule

In the intensive search for extra-terrestrial life scientists always look for water because of its crucial role in supporting life. They recognize that without liquid water, physical life is impossible because water has a number of unusual properties that are crucial to maintaining life. There is no evidence that any other simple molecule exists that…
