Re: Solar System B

Eh, the event could get there eventually. Be fair: The Div C event only just got around to adding in exoplanets, our knowledge of exoplanets is all VERY recent, and this Solar System topic is brand new! I'm personally pretty excited, I remember when I did Solar Sys the purpose was very...broad, so ...

Re: Optics B/C

Chalker, are you reading this. I mean some people will have to spend a bit more time but it will raise the standard of competition quite a bit. It can also make building the LSS significantly more difficult, if not impossible for some hosts, especially if they already have one from last year. Getti...

Re: Solar System B

The planets this year are Mercury, Venus, Earth, and Mars right?
No Earth. It's honestly a shame that this event doesn't cover any exoplanets, since there are many fascinating systems out there.

Re: Optics B/C

Here's the test I used for the UT Regional last season (given to both B and C division). It's probably much harder than most would expect in terms of content and math involved. I think surprisingly Beckendorff ended up beating every team (B and C) in terms of test points (aka excluding the LSS).

Re: Fermi Questions C

And we return! How fast, in decimeters per hour squared, would a 2017 Volkswagen Beetle, which is currently orbiting the Earth at 700 km altitude, have to be accelerating in order to use as much power as the sun emits? Maybe|20? We can say P*t = 1/2m*v^2. Solving for v, v = sqrt(2P*t/m) Differentia...

Re: Optics B/C

Any good resources for this event? A lot of my questions have been pulled from college-level texts (AP-level questions are what I'd consider the "easiest" level in my tests) and even some graduate, and I was wondering what resources were considered to be "normal" difficulty for this event.

Re: Fermi Questions C

Best event (had a blast proctoring this at MIT last year)!

Re: Texas 2017

Such is the way of Texas State, arguably one of the most volatile tournaments in SciO.

Also, @jkang, I think the first polarization would be and the second would be
Oops, you're right about that.

Re: Optics B/C

I actually just went over this in my EM class. Due to the way Maxwell's equations and boundary conditions at the interface work out, there'll be two different polarizations of light with separate equations - one where the magnetic component of the wave is parallel to the interface, and one where the...
