I need to find out a good way to estimate the number of samples I need to take for an analysis. I will have some HLW and LAW simulant that I will have tested for certain markers. I need to make sure that there is only a +/- 1% difference from the control specimen to my samples. Statistically how...

I think one problem with making physics a 9th grade class is the difference in math backgrounds that students have. At my highschool most students were taking either algebra or pre-algebra in 9th grade, while others were taking everything from geometry to pre-calc. Schools need to be able to...

Job 1: Had a Chemistry teacher randomly ask if I wanted an Internship at the research lab outside of town for the summer. I worked there for two summers. Job 2: My dad seems to know everyone in the NDT industry and I got a job through that connection during college. Job 3: The guy my mom was...

For our school it is quite possible to graduate in four years, provided you are willing to work at it, take the full load, and pass all of your classes. We have a program that we were given our freshman year detailing which classes needed to be taken each semester, and as long as you stay on...

As an undergrad I have seen the current "boot camp" at my univeristy, and at least for Aerospace it has seemed a bit backwards. While the first year and a half was relatively easy, we were not given too much of a taste of Aerospace or engineering. After that the classes became...

Thanks for all the advice, I will probably take it either this fall or next spring depending on how my class schedule looks. I think I will end up taking the general, as the mechanical has a few sections not covered in aerospace, specifically HVAC, Fans and pumps, and the material processing...

I have not come to the point yet when I am going to take the EIT exam, and have not yet decided if I am going to. I have read a lot of differing opinions on the EIT and PE exams in the forums over the last few months. One thing that I am curious about, as a Senior in Aerospace engineering which...

The only way I have found the pressure distribution over a body of revolution other then a sphere was to use CFD. We just wrote codes in fortran to do this.
