The secret to scientific discoveries? Making mistakes | Phil Plait
New Section
In this section, the speaker discusses the misconceptions about science and emphasizes that science is a process of understanding objective reality based on evidence.
Misconceptions about Science
- Science is not just a collection of facts; it is a way of thinking and understanding objective reality.
- The ultimate goal of science is to understand objective reality based on evidence.
- People can be biased and easily fooled, so science has built-in mechanisms to minimize bias.
New Section
This section explains the process of scientific inquiry and how scientists minimize bias in their research.
The Scientific Process
- To conduct scientific inquiry, one starts by observing something and questioning it.
- A hypothesis is then formulated as a possible explanation for the observation.
- Predictions are made based on the hypothesis, which can be tested through experiments or observations.
- Peer review plays an important role in science by allowing other experts to evaluate and provide feedback on research.
- Scientists continuously refine their hypotheses through testing and modification until they reach a satisfactory explanation.
New Section
This section highlights the importance of admitting when one's hypothesis is wrong in the scientific process.
Admitting When You're Wrong
- Scientists are human and can have biases, but part of the scientific process involves minimizing these biases.
- Admitting when you're wrong is crucial for scientific progress.
- The experience of being wrong provides opportunities for learning and discovering new things.
New Section
This section emphasizes that being wrong in science is not necessarily a bad thing because it leads to further exploration and understanding.
Embracing Being Wrong
- Being wrong in science means there are more things to discover and understand.
- Scientists love puzzles, and the universe is the biggest puzzle of all.
- It is important to let go of ideas that do not fit into the bigger picture and be open to new possibilities.
- The price of doing science is admitting when you're wrong, but the payoff is knowledge and understanding.
New Section
This section discusses a specific example in astronomy where scientists had to challenge their assumptions and discover that other stars also have planets.
Discovering Planets around Other Stars
- Historically, astronomers believed that the Sun was special compared to other stars.
- Through scientific inquiry, it was discovered that the Sun is just one star among millions.
- This led to the question of whether other stars have planets as well.

The speaker discusses being on the edge of what they were able to detect.
On the Edge
- The speaker mentions being right on the thin, hairy edge of what they were able to detect.
