categories (which is the majority of them, at least in our own galaxy) is as follows: First deduce the likely temperature and size of the star from its dominant colour and the atomic spectra present in its light (temperature is related to colour, and different chemical elements are produced under different conditions of temperature and pressure, which in turn depend on the mass and age of a star). From these we can work out the likely luminosity. From the luminosity we can deduce the stars absolute magnitude [1] (i.e. how bright it would appear at a standard, fixed distance of 10 parsecs from us). Comparing this with the star’s apparent (i.e observed) magnitude, we can then calculate it’s actual distance from us. To me, this method of deducing a star’s distance from us merely by studying its light, and then doing a few calculations based on thermodynamics, nuclear physics, atomic physics and stellar dynamics, represents one of the most beautiful examples of the power of human ingenuity and careful, deductive reasoning in the history of science.

History is all over the place in New Jersey. I can hike 4 miles into the Official Sega Saturn 2023 T Shirt and find the foundations of a 18th or 19th century farmhouse . I can find the vestiges of 18th and even 17th century mining operations and in some places enter the old mine to check out the bats and hundred+ year old drill holes. I can (and do) visit battlefields from the American Revolution and houses where George Washington spent a winter or a night. I can see a play in a small, local playhouse or spend an afternoon in a top notch craft beer brewery or halfway decent winery. I can go to a minor league ball game or cross the river and see the Yannkees or Mets play. I can watch the “NY” Red Bulls soccer team playing in a really nice soccer stadium or the NJ Devils ice hockey team. I somtimes go to places such as the Newton or Wellmont theaters to see major musicians perform.
