  1. HI MR. REID! :) Sidney, Rajee and I totally found your website! We caught you :D
    Extra credit for us? See you tomorrow in 5th period

  2. Mr. Reid,

    While surfing the web for inspiration on modeling consecutive (pseudo) first-order chemical reactions, I stumbled across your paper on decay chains. It was just what I was looking for. The spreadsheet you provided was very helpful in simulating up to five such chemical reactions and it could, of course, be modified to accommodate more.

    I found many other tidbits on your website to be very interesting and I especially love the photo of the Al vs Al confrontation (http://wordpress.mrreid.org/2013/01/28/whipple-shielding/).

    Thanks for the help and inspiration

    Best regards,

  3. Loved it. Greatest teacher ever 9apart from maybe my science teacher)
    Go your website!

  4. Hi Mr. Reid, I’ve coded an activity calculating program that also calculates the amounts/activity where the first isotope in the decay chain is created at a certain rate. It also includes branching factors from one isotope to another and you can set the starting number of atoms for any isotope in the decay chain. https://github.com/BenPalmer1983/activitylite

  5. Thanks for this great work. Enabled me to visualise decay chains a lot better!
