Summary of Neil Degrasse Tyson explains How science works

00:00:00 - 00:10:00

Neil Degrasse Tyson explains how science works, and how new discoveries can lead to new truths that may contradict earlier beliefs. He points out that science is not a matter of blindly following mathematical equations and observations, but is instead a process of constantly testing and refining hypotheses. Ultimately, this process is guided by emergent scientific truths, which are discovered by looking at previously unrelated phenomena and applying the principles of mathematics and physics to them.

• 00:00:00 Neil Degrasse Tyson explains how scientists are constantly wrong, but they are still able to progress and learn new information. He also discusses climate change skepticism and how it is simply a lack of knowledge about science.
• 00:05:00 Neil Degrasse Tyson explains how science works, and how new discoveries lead to new truths that are true even if people don't believe in them. He points out that Isaac Newton is still considered one of the greatest scientists of all time, even though his laws of motion don't apply to all situations. He goes on to explain that even though Newton's laws are accurate, other people have found other laws that work better in some situations. This is the process of science – discovering new truths that often contradict earlier beliefs.
• 00:10:00 According to Neil Degrasse Tyson, science is not a matter of blindly following mathematical equations and observations. Science is a process of constantly testing and refining hypotheses, based on empirical evidence. This process is ultimately guided by emergent scientific truths, which are discovered by looking at previously unrelated phenomena and applying the principles of mathematics and physics to them. In a free country, people should be allowed to disagree with scientific findings, but they should not be in control of anything that involves the Earth.
