Dear all,
Many times I write questions then choose the topic where I want they appear and finally I do not see these questions in the chosen topic! It continues many times! What is it? Bug, censor, or aliens? Dear Professors of researchgate.net, could you explain me it!
Dear Physicists,
I included these my school questions below. I would be appreciate of your references and comments.
Thank you for an advance,
Dear p hysicists!
Below I include my questions about which I talked above:
1. Who invented equation connecting torque and angular momentum? Is he Newton?
2.What is the minimal set of physical equations in mechanics to determine inertial mass (preferentially without the use of torque equation)?
I would be grateful for references!
Dear collegues!
The below is the last question which does not appear in any topic I chose.
Do physicists really use Eucid definitions determining a straight line, point and plane in their physical theories?
Here is a quote from Euclid elements:
1. A point is that of which there is no part.
2. And a line is a length without breadth.
5. And a surface is that which has length and breadth only
Mathematicians dislike these definitions but physicists are quietly using it in every theory. Am I right?
