“The time has come,” the Walrus said, “To talk of many things: Of shoes–and ships–and sealing-wax– Of cabbages–and kings– And why the sea is boiling hot– And whether pigs have wings.” My aspirations are not nearly so noble. I just want to talk about HYDROPONIC GARDENING. I have tried to grow lettuce for years. Each time […]
Are you ready for a challenge? How about growing some tomatoes without soil? I’m going to give it a try, but I have to admit I’m going to have help in the form of a Baby Bloomer. Hmm… Doesn’t seem fair. To even things up a bit, I’ll also grow some tomatoes with all of […]
The collapse of the Tacoma Narrows Bridge, aka Galloping Gertie, in November of 1940 was pretty spectacular. So spectacular in fact, that people are still talking about it. Here’s your chance to see why.
I’m nearly done with a book on Quantum Mechanics for a series at Rosen Publishing. Once it’s off to my editor, I’ll be back to blog. In the meantime, here’s an excellent explanation of the Higgs Boson from no less than Peter Higgs himself. Enjoy!

I don’t know about you, but there are times when I want something to eat that isn’t going to knock my glucose out of whack. This is especially difficult since I am often on prednisone–which knocks my glucose to the moon as it is. Here is my version of an easy-to-make, good-tasting, snack that won’t […]
Innovators amaze me. The people who look at a take-out coffee cup and visualize a way to standardize the openings and lids. The people who realize a bit of sticky substance on a slip of paper can solve an everyday problem. The people who take a zipper and make it more!
Who doesn’t love a bridge? They span a space and bring people safely from one side to the other. They work in all types of weather. They are forms of art and function rolled into one. New York is getting a new Hudson River crossing. This could get interesting.
Murmuration. Tintinabulation. Some words just can’t help but pique your interest. Check out this video of a murmuration of starlings. It’s a fluid flow of birds!
Does the average citizen of Beijing have the ability to take significant action or join in a process of creating better air quality? It’s an important question because their air quality affects us all.
Coming soon – an interview with Brad Gemmell – a researcher who discovered the secret to the propulsive power of jellyfish!
This video does an outstanding job of making the Reynolds Number meaningful. More about the use of the Reynolds Number in scale model testing in future posts!
This is the first post in a series on jellyfish. It explores the way jellyfish move through deep water. Sometimes it appears that jellyfish simply float and move with the water in the waves. Other times it seems that the wind blowing across the surface of the water is pushing the jellyfish along the surface.
This experiment has been referred to as the central mystery of quantum mechanics. Here it is explained by Professor Jim Al-Khalili.
This simple video demonstrates the effect of tension and compression on a beam bridge. More Types of Bridges: Beam
Cantilever bridges are subject to the two basic forces that are in effect for all bridges. These forces are compression and tension. In a cantilever bridge, with the space between the cantilevered portion spanned by a suspended deck, the compression and tension are straightforward. As you can see in this diagram above, from Merriam-Webster, a […]
When you see this image, you’ll know the post is about something related to Air Quality. The post may include an interview, a news item, a TED Talk, or a report on the latest research. Whichever it is, it will be worth your time. It will also include a link that you can use to […]
In this BBC presentation, Physicist Dr Helen Czerski takes us on an amazing journey into the science of bubbles. Bubbles may seem to be just fun toys, but they are also powerful tools that push back the boundaries of science. From the way animals behave to the way drinks taste, Dr Czerski shows how bubbles […]
This video, courtesy of PBS, does an outstanding job of explaining the forces of tension and compression at work in a cantilever bridge.
My mission as a science writer is to make the complex simple. It frustrates me when I encounter well-educated people who insist there is no simple way to explain x, y, or z. Having written an entire book about applied fluid dynamics for laypeople, I also frankly find this hard to believe. SO – one ongoing project of […]
There are four main types of bridges. The cantilever bridge is one type. It gets its name because it is built using cantilevers – horizontal structures that are supported on only one end. (Think diving board.) With a cantilever bridge, there is a structure that supports one end of the deck. This deck structure can […]
