  • ASI120MM Astronomy Camera
    much astronomy all year Plugged everything in started up the process and made sure I m getting images time to calibrate the autoguider no movement Hmmm check cables poke and prod retry no movement After an hour or so of this in the dark break out the Shoestring Astronomy GPUSB plug it in calibrate mount moves and guides just fine Do I have a dud I don t know yet

  • BSA Astronomy
    for Ten Mile River to try to get the scouts through the astronomy merit badge The operative word here is try because it s not actually possible to do in the time frame allowed by camp but we did work on them getting through the visual observations which is a big deal 10 constellations 4 of which are in the zodiac 8 conspicuous stars 5 of which are first magnitude plus sketches of the Big Dipper over a 2 3 hour period to observe the sky rotation We ll call it a limited success since all of the boys managed that part we practiced every clear night before the 3 hour observing session on Thursday And they all learned to use a planisphere and were required to use it to plan out what things they were going to observe that night I did fire off an email to BSA national about the updated Astronomy merit badge requirements I m not at all happy with the Observe a planet and describe what you saw requirement as it s too vague We did do that one during camp but we used a telescope to observe Saturn so there was a bit more

    Earth The answer is interesting It s the same no matter how far apart the two points are 42 minutes In The gravity tunnel in a non uniform Earth Am J Phys 83 231 237 2015 there is a new take on this using a non uniform model for the Earth based on the actual data the Preliminary Reference Earth Model aka PREM That model says the actual travel time

  • Superball Physics!
    tangential COR make for fascinating behavior like how you can make a superball bounce back and forth by giving it backspin On each bounce it will reverse spin and keep going for quite a while The paper is fun but they also do a lot of careful measurements on how different types of balls slide when they hit a surface To do that they used a very low tech approach
