Experimental conclusion
For example, a mathematical experiment is "measuring the sum of the internal angles of a plane triangle with a precise ruler and goniometer"
Experimental purpose: to explore the law of the sum of internal angles of plane triangles on the earth.
Experimental equipment: precision ruler, precision goniometer and flat glass.
Test method: Make a triangle on the glass plate and measure the sum of internal angles.
Experimental steps: By randomly making triangles, and making typical triangles and extreme triangles, the sum of internal angles is measured.
Experimental data: record the three-point coordinates of each triangle and the sum of its internal angles.
Data processing: estimate the measurement error of ruler and goniometer, estimate the error of triangle point selection, draw the sum of the internal angles of each triangle on the map, and mark the error.
Data analysis: judging rules, such as 180 degrees? Or, because of the error, I can only guarantee that the sum of internal angles is between 179 and 182 degrees.
Experimental conclusion: Euclid geometry, for example, was overthrown. Our earth is not a straight space.
