1. ### I Just for fun: math brain teaser

My answer looks like this (translating from my pen+paper notepad): a+b = a+a*b 1+1*4=5 2+2*5=12 3+3*6=21 8+8*11=96 my friend got 40, which I can also see. I am not sure who is correct. Please let me know and let’s put our heads together and have fun.

### B Brainstorm: Is absolute zero relative

I know that absolute zero is impossible to achieve but we can get close. According to google the coldest temperature ever reached in a lab was 0.006K. Do you think this is because while the atoms are moving very slow relative to the observer they are still moving at the velocity of Earth's...

Hi, I'm trying to design a contraption for a project that will move an item/box up and to the side. I have a picture of what it should look like and how it should look like but I need help with the mechanics of it. The box's starting position is In the ground and under a slap of metal or wood...
6. ### Brainstorm and confusion of concepts

I know several math formulas, like which I will write below. \int_{x_0}^{x_1} f(x) dx \frac{\int_{x_0}^{x_1} f(x) dx}{x_1-x_0} \frac{\int_{x_0}^{x_1} f(x) dx}{2} f(x_1) - f(x_0) \frac{f(x_1) - f(x_0)}{x_1-x_0} \frac{f(x_1) - f(x_0)}{2} \frac{f(x_1) + f(x_0)}{2} And I know too that...
