Re: Astronomy C
Do you guys know where a good source would be to get to the more complicated mathematics portion of this event? I think I have built a good basis already and am ready to try to reach for another level.

Re: Lever Tasks
In your opinion guys, what constitutes the beginning and ending of the third class lever task?
In my opinion, the lever activating is the beginning and the ending is when the object stops at its final placement. Is this similar to what you guys are getting at?

RandomPerson and I both tried the question independently and both of us got the answer above - I'd say key is wrong, unless all three of us are doing the same thing wrong and not realizing it.

Re: Astronomy C
Can someone walk me through what I am doing wrong in the MN Regionals Test on the test exchange # 27? So, they gave the light curve of the Cepheid Variable. I determined the average apparent magnitude to be + 24.9. I then said that the period was 25 days. I used this in the period luminosity relatio...

Re: Circular to Linear
I also used the winch system. However after reading the clarifications and seeing that no gears were allowed...I was wondering does the motor have gears inside of it that would cost points for the task? I had asked this question earlier in the year and Dark Sabre and Primate do a good job explainin...
