No, Ptolemy did.
He made many experiments and observations in the field of physics in general.
True. An inference is a tentative conclusion drawn from observations and available evidence. It involves interpreting data and making logical deductions, but it is not definitive and may require further investigation to confirm its validity.
Having two independent observers increases the reliability and validity of the observations by reducing bias and increasing the consistency of the results. It also helps to ensure that the findings are not due to chance or individual interpretation.

Scientific Theory is tested by observations and experiments predicted by the theory. If the observations confirm the theory the theory is validated if not the theory is not validated. Experiments themselves need validation, often there are errors in the experiments or observations, e.g Michaelson and Morley Aether experiment and red shift observations.
If it is possible, at least two people should confirm the accuracy of facts and the validity of assumptions during the problem solving process. This helps ensure accuracy.
Newton confirmed his hypothesis about gravity by developing the Universal Law of Gravitation, which described the force of gravity between two objects. He used this law to predict the motion of the planets and the Moon, which matched observations made by astronomers, confirming the validity of his theory.
Scientific observations should be repeatable to ensure the reliability and validity of findings. Repeatability allows researchers to verify results, confirm hypotheses, and eliminate the influence of random errors or biases. This reproducibility is essential for building a robust body of scientific knowledge, enabling others to trust and build upon previous work. Ultimately, repeatable observations enhance the credibility of scientific claims and foster progress in understanding natural phenomena.

Scientists routinely make predictions based on their hypotheses in order to test their validity. These predictions outline expected outcomes or behaviors under specific conditions. By conducting experiments or observations to gather data, scientists can confirm or refute their hypotheses, thus advancing their understanding of the underlying phenomena. This rigorous process is fundamental to the scientific method.
