I'm a math and physics tutor in the Summit, NJ area. I've put a lot of useful information (strategies, formula guides, quizzes, and more) for SAT and ACT study on my tutor page.

What are the colors of the Empire State Building tonight? Where can you go to get a suntan on a grassy field that seems to be floating in the Hudson River as cruise ships pass by? In Hoboken, NJ, you can see the New York City skyline and get that suntan. Check out the view from the Hoboken Pier Cam.

A few years ago, I made an extremely tiny contribution to science. But the journey was an experience of a lifetime and gave me opportunities I never could have imagined. My Ph.D. thesis is available for anyone interested enough to look here.

When is the next full moon? From the earth, we only see one side of the moon...what does the other side look like? Check out the Moon Page for the answers and other interesting information about our nearest celestial neighbor.

Long ago, a web page displaying a tomato with a shadow that you could click on was quite an achievement. If you enjoy making bread at home, however, the recipes I made (found here) still work pretty well. You may also be interested in some helpful information about flour weights.

At some point, I thought I might scan every ski map I have (and I have quite a few) and put them up here. I made it to two maps. But, at least they are interesting ones. You can seen them in my tiny collection of old ski maps.

It is nice to have an at-a-glance view of current weather conditions on a web page with no advertisements. Take a look at my (northeast U.S. oriented) Quick Weather Page. At least serveral links likely are broken, because providing internet weather usually requires ad revenue, but hopefully something interesting will still be there.

I used to work in one of the buildings next to the World Trade Center in 2001. Some pictures of "ground zero" taken from the World Financial Center nine days after 9/11/2001 are here.

Play Mathle, a mathy version of the game Wordle! I replaced some of the Wordle words with words commonly found in math textbooks in order to give my students something to do which is fun and math-related. Purely for educational purposes. Note: there are only so many five-letter math-related words, so the word list repeats every four months or so.
