I also love it when people incorporate science into their Kickstarter pages

Just watching him throw it on the grill for less than 5 minutes was crazy to me. Especially since my homemade pizza takes 15-17 minutes to bake.

I saw this thing on Kickstarter this morning and I have to say it's pretty awesome. The structure of it is pretty cool and the end product looks delish https://www.kickstarter.com/projects/1906570847/mighty-pizza-oven-2-mpo2

Homework Statement Over the years, buildings have been able to be built out of lighter and lighter materials. how has this affected the natural oscillation frequencies of buildings and the problems of resonance due to passing trucks, airplanes, or by wind and other natural sources of vibration...

Oops that was supposed to be 350 N/m not N.

This would make sense since I always forget about significant figures.

I actually found the answer to it. It states 350 N/m which I can see from rounding but it didn't say anything about estimating in the problem. Maybe an unfortunate mistake

I'll re-work it again and see if I can find a different way

Homework Statement Find the stiffness of the spring in a child's pogo stick if the child has a mass of 35kg and bounces once every 2.0 seconds. T = 2.0 seconds m = 35kg Homework Equations T = 2π√(m/k) The Attempt at a Solution Using the above, I figured k = mπ2 which worked out to be 345.44...

I recommend almost any Dover book. Most are older books with new covers but they're great.

I haven't taken the Physics GRE yet, but with the Mathematics GRE I spent a lot of time on Google finding practice tests and free materials. A helpful tip is to actually practice with the 170 minute time limit.

This is the best advice. I would do these and if you get stuck on one, take it to your professor during their office hours for guidance. Give it at least a day or so attempt though before you take it.

The three in concerned about are Modern Physics, Statistical and Thermal Physics and Quantum Mechanics. I see lots of "particle" and "atomic" in the descriptions

Ah ha! So I was looking through the physics classes I will have to take and noticed a lot of topics dealing with atoms and the like. Would it benefit me to take the first installment of basic Chemistry? I don't want to take the lab portion just the lecture section if it would be a tremendous...

It must have been fancy shmancy because I got a response rather quickly.
