Letters to the Editor

Letter: How are you feeling?

To the Editor:

Are the news stories of the day causing illness and fatigue in your life? Are you sick and tired of the wall, wall, wall, national emergency, a fictional hate crime reported on ad nauseum, etc.?

How about some good news from a potentially tragic hit-and-run accident which sent a 7-year-old girl flying and tumbling about 8 feet in the air and landing about 30 feet away between two parked vehicles shown on the national TV news programs Feb. 18.

She gets up, has the presence of mind to pick up something she dropped and runs to the safety of the sidewalk. The good news is that, other than some bruises, she was uninjured, and the driver was later arrested.

The others in the room watching the news with me exclaimed, “How could she be uninjured? That could have killed a grown-up!”  

I replied, “She has a higher strength-to-weight ratio compared to an adult.”

I could see the question marks hanging over their heads, “Whaa…? Huh?”  

So, for your educational enrichment, which will not enhance your income:  A person’s weight is proportional to their volume, and volume varies as the linear dimensions cubed (height, width, thickness).  

A person’s strength is proportional linear dimensions squared. If the grown-up has twice the linear dimensions of the 7-year-old girl, that person will have eight times the weight (two cubed) and only four times the strength (two squared). The adult will have the strength-to-weight ratio of the little girl, or conversely, the little girl has twice the strength-to-weight ratio of the grown-up.

Remember when you were an infant and rolled out of the bassinet onto the floor? You cried, but you weren’t injured. Or a toddler falling four stories out the window of a high-rise and surviving.

If Godzilla is scaled up from human size 10 times, his weight would increase 1,000 times, but his strength increases only 100 times and he would be crushed under his own weight.

Now you know.
