I'm only a uni student at the moment and this feels more like something you learn from experience than something taught in a lecture but I'll thought I should ask anyway. Is there an easy way to select materials for engineering projects? I was hoping to find there is a nice dictionary sized...

I'm sure this is elementary for this forum, but can someone help me figure out if my son's science fair project results are correct? He rolled his toy car, with and without weight added, down hill and measured the time to get to the bottom of the hill and the distance traveled once the car hit...

May you guys look over my program I can't figure out my mistake. It looks i am printing the names two times but can't find the issue in the program. What I bold is what is what I got wrong. #include <iostream> #include <vector> #include <string> using namespace std; int main () {...

Help. I am having a problem choosing a topic for my math research project. Anybody have any ideas they'd like to share ?

I can't find any good sources on the science behind Project Greenglow. All the articles I see are full of fluff. Are they trying to divorce gravitational mass from inertial mass? i.e., trying to get more gravitational mass out of less inertial mass, or I should say more space-time curvature from...

So, like the title says, I'm doing another project. The kicker this time is that I don't even know how to start. Last time I was able to post some code I had already messed around with (and messed up) but this one I'm not even sure how to begin. I've already done some of the work with...

Hey guys, I am currently working on a uni MATLAB group project for blast radius, thermal radius etc. Apparently these formula are the best possible to use: r_thermal = Y^0.41 * constant_th r_blast = Y^0.33 * constant_bl r_radiation = Y^0.19 * constant_rad But can anybody tell me what...

Hello there, A couple of us have been tasked to come up with a way to produce drinkable water from a source which is turbid and I'm trying to figure out a way to do this. It has to be cheap and work well without needing too much knowledge to operate. My initial idea is to use a coagulant...

Hello Forum, Does anybody have suggestions as to how we can use IMU's (accelerometers and gyros) to determine the gradient of a road during a braking event. We have wheel speed inputs so can calculate decelerations independently from the IMU. Thank You Tim
