    Thank you for the shoutout Dylan, and thanks for your help! So a number of us (Andrew, Ian, Hiroki, Jeremy, Peter, Dylan and myself) managed to do the experiment and we were able to get to with 1-2% of the moons true distance with the larger baselines. Not bad for backyard measurements!

    Great upload mate ☺real science and my kinda party. It's kind of difficult to get precise measurement of the Moon because of its unusual orbit. Each orbit and distance differs from the previous one hence why they depend on the laser sensing experiment. I use magnitude in comparison to stars along with powers of 10 mathematical form ☺

    Your formula needs changing slightly to take account of the angle between your baseline and the direction of the moon. If the baseline is at a perfect 90 degree angle to the direction of the moon, then your calculation will be accurate. If not, then it will be an underestimate.

      @@DylanODonnell Khan academy math is really good. I did a TPP (tertiary preparation program) with USQ back in 2017 with the aim of doing a Bsc majoring in Astronomy and had a horrid time with the maths (maths all online only, no lecturer, head lecturer at the Ipswich campus taught 3 classes each at both Ipswich and Springfield lakes campuses; so was really hard to get a hold of). And, even worse, no tutor available (only for the beginning and intermediate maths subjects). I can learn the material, but not in a compressed period of time like they expect (i'm older, nearly 50, and my learning ability in the past few years has really slowed down).
      It was a very unpleasant experience to say the least.

    • @DylanODonnell
      @DylanODonnell  5 лет назад +1

      mrtheoden you are right on both counts, Khan academy is a fantastic resource especially those original maths tutes that go right back to primary school level - which I happily admit I refer back to! And maths isn’t hard, just a bit of a plod and as you say it’s hard to get support in an online course. The Swinburne course is very maths light - so it can’t be transferred to other unis if you choose to move institutions. I’m only doing a post grad cert though, it’s unlikely I’ll go on to masters where the math gets more intense.

    • @davepastern
      @davepastern 5 лет назад +1

      @@DylanODonnell have you got a link to the course in question? How do you define math light? USQ's program wasn't super heavy on maths I believe, certainly not the same level as a similar degree at UQ or ANU. I'm more curious than anything - I've admitted to myself that I am simply too old to be considering doing a degree.

    • @DylanODonnell
      @DylanODonnell  5 лет назад +2

      I’m at the pub so forgive me but google Swinburne online astronomy for the course options. I’m doing the grad cert so I only have to knock over 4 subjects to get the equivalent of a bachelor degree. Re maths light .. you could get zero points on all the maths questions and still pass. No exams. Take home tests and a heavily weighted essay. It’s geared up for science communication really. I should get a commission for these referrals .. quite a few subscribers have enrolled :)

    @Chrisjones-uh1xm 4 года назад +1

    I thought modern astronomers used a laser to measure the distance by bouncing a laser off of the moon with mirrors left from the moon missions. Truly mind blowing we have lasers that shoot 230,000 miles away off of mirrors and not hitting a single satellite or having trouble with the rotation or orbiting

    • @Gkc57Ii
      @Gkc57Ii 9 месяцев назад

      Yes, that’s a much more accurate way professional astronomers measure the distance to the moon. This video is about an amateur DIY method. Your other comments make no sense. Satellites would be too small to interfere with the laser.
