National Geographic has a terrific device known as the Crittercam. The penguin on the left is wearing one. He’s not the only animal that has. It’s been worn by a variety of animals, including humpback whales and a bear cub. The idea for the Crittercam came to marine biologist and filmmaker Greg Marshall in 1986. […]
So which is better? To be a Yankees fan or a Mets fan? As a lifelong Yankees fan, there’s no doubt in my mind which is best. NJIT Professor Bruce Bukiet is a lifelong Mets fan. Here’s Baseball’s Chief Geek’s hilarious explanation of why it’s healthier and more productive to be a Mets fan. “I tell people […]
How does NJIT Professor Bruce Bukiet’s baseball projection model work? Baseball’s Chief Geek and I discussed what it takes – in terms of logic and computing time – to model a baseball game. We also discussed the difficulty of modeling baseball compared to sports like basketball or football. It’s to Bukiet’s credit, and talent in […]
It’s Opening Day! The start of the baseball season. What could be more? For the rest of the week, I’ll be posting excerpts from an interview I had with NJIT Associate Professor of Mathematical Sciences, Bruce Bukiet, aka Baseball’s Chief Geek. He’s a mathematician with a bias toward math with a purpose. His annual projections […]
“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 […]
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 ruin your night. It actually tastes pretty good, too.
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.
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 […]
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 […]
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 […]
