    Question 12 says "Since June 2018, the US Patent Office has issued… patents." The answer is given as 10 million. Seeing as how the 10 millionth patent was granted in June 2018 (228 years after the first patent was granted), I seriously doubt another 10 million have been granted in the last 5 months. Did the question mean "As of June 2018…?"Yes I will correct, thanks!

    Five, although I thought I'd pressed the right answer for the remote control and the results say otherwise (probably fat-fingering on my part).

    Missing option for #6: aircraft carrier. :wink:

    There is an issue with the AJAX submission thread. I have reverted to POST and it works again. Enjoy! Post those scores!I hate AJAX. It's a nightmare to debug and update …

    Something appears to be broken. Anyone not getting a score when you press submit?Maybe I'm the one to blame. If so, then I discovered a bug. I think I had been first who entered the quiz, ran shortly over it, and then wanted to know the results without doing the quiz and hit "submit" on an empty list. As a result, the first question had vanished, so I had to refresh to get it back.

    Now I wanted to test it. And each time I hit "submit", this time with a filled out formula, again the first question on the lists vanishes. I stopped the procedure after I "killed" the first 4 questions. So my suspicion is, that something with the submit button is wrong. The underlying code seems to delete the first list entry instead of an evaluation. Perhaps a fix is to remove it and set it again, if that is possible.

    Sorry, uhm no sorry for that: I'm too curious. I continued and "killed" the rest of the questions untile there was an empty sheet. Then I hit "submit" again, and ever since the page has gone in state "loading" – which it can't since all list entries have gone. Funny bug.

    I protest against Edison. IMO Bouly resp. the Lumières were first, maybe Anschütz or Reynaud, but never ever Edison.
    Not the last time Edison had stolen from others.
