The secret to scientific discoveries? Making mistakes | Phil Plait

  • Published on Apr 11, 2019
  • Phil Plait was on a Hubble Space Telescope team of astronomers who thought they may have captured the first direct photo of an exoplanet ever taken. But did the evidence actually support that? Follow along as Plait shows how science progresses -- through a robust amount of making and correcting errors. "The price of doing science is admitting when you're wrong, but the payoff is the best there is: knowledge and understanding," he says.

    I watch sci-fi movies a lot. I had a very misconception about scientists. I thought that scientists are the most boring people in the universe but this guy changed my thoughts since I watched crash course astronomy. He is awesome...... Just awesome

    It's too bad politics, religion and society don't function like the science Phil described. Also in school, teachers always stress that students need to be perfect in their homework, quizzes, exams, grades --- while mistakes are treated as criminal acts.

    As a scientist, I feel like more often you find your self arguing with the scientists who double down on their mistakes and fight till the bitter end, or at least until the conversation has died down and they can change the subject in a face saving way. Moreover, I'd say that's the human side of science, because what's more human than refusing to admit you made a mistake?

  • phunnyfill
    phunnyfill 9 months ago

    The religion of science. I am astounded by how many people are freaking out over the black hole CGI "photograph". It takes more faith to believe in this crap then it does to believe in most other religions.
    Most science is factual and legitimate, but a great deal of astronomy and geology are completely fabricated. Unproven theory is called indisputable fact. You know I'm right, but hearing your religion is false is too much to bear for most. So, instead of intellectual honesty I am prepared for attacks and name calling.

    • fiona fiona
      fiona fiona 9 months ago +1

      Nothing is named an indisputable anything, you (as a likely religious person) just don't remember what sort of evidence we needed to prove it to sufficient certainty (like it took to convince the Vatican)

    Trillions of dollars later, science has done a crap job of curing cancer, in fact these days just about everyone has cancer...we can't even make roads that last or fix the billions of potholes in our roads, or failing bridges, waterlines and other infrastructure, it takes years to do basic road work, we did construction projects 70yrs ago that would be impossible now, we can't stop forest fires AT ALL, no science for that...science is not getting us anywhere besides consumer products.

    • BJ C

      1. Cancer is not one disease. It’s a huge number of diseases that all relate to uncontrolled cell growth, but in many different ways.
      2. The cancer cure rates today are DRASTICALLY better than they were 20 years ago and a universe away from what they were 60 years ago.
      3. The science is there and has been done for long lasting materials. But politics (and lobbyists) and some times costs get in the way. I think your problem is with politics. (Mine certainly is on this issue).
      4. Same, but to a lesser degree for forest fire science: politics and people’s inability to trust advancements in science when they are contrary to traditional approaches. Again, a problem with people’s distrust of science (and misunderstanding it).
      5. I wouldn’t crap on science; if you think about it, things really are much better now in virtually every metric and science has played a role in all of them.

    • BJ C
      BJ C 9 months ago +1

      It was exactly as described. The discussion of the search for exoplanets was a tool to highlight the fact that science is a process. And, that process, is critical to advancement. The title should reflect the overarching message.

    first picture of a black hole was brought to the public and you are talking about exoplanets.. pfff, old farts

    • BJ C
      BJ C 9 months ago +1

      Of course, without the advancements in science and tech that the search for exoplanets brought us, we wouldn’t have been able to acquire and process the images of the black hole. And you are missing the bigger point of his lecture: that science is a process. We are talking about the most misunderstood aspect of science and one that leads to many folks’ distrust of science. The search for and discovery of exoplanets was a tool to highlight this, not the singular point of his entire lecture. I’d say these farts are pretty important, lol.

    You can very well discover a lot without making mistakes. Why do we want to make people think science is so easy and coincidence? 👎

      @Brooke B so Newton, Einthoven, Darcy and others who had a clear goal they reached not by mistake all didn't understand what science is about?

    • Brooke B
      Brooke B 9 months ago

      It is clear that you are not familiar with science.
      He isn’t referring to a pharmaceutical scientist making a mistake and accidentally killing people.
      He is referring to discovery. It was once accepted that the Earth was the center of the universe, if we assumed science is ALWAYS correct we would never know the wiser.
      When you start a new experiment you have to have a hypothesis, as he mentioned.
      Often, it is wrong.
      So you change it.
      Experiment again.
      And repeat this process until you have something tangible or realize you have been wrong the entire time.

      Not once did he say science was easy.
      He said science was human.

    These guys get a lot of $$$ to sit around & dream...... I keep hearing in America there is no money for this OR that... emmmm...... I also have observed that people whom have enough $$$ create "Job"s, for their own. Example, I knew this family, the husband made mega buck but dumb as a box of rocks for he could not see or detect what I saw, that his wife whom brought in 2 Africans from the 3rd world to Educate & support them while they lived in their home, they were F'king his wife & her daughter the whole time. The daughter is a complete Ho' & her parents set her up in a shoppe so they could make it look liked she worked calling her self an Artist....while giving Blows on the side downtown. Crazy, upside down world we live in.

      Though, is “scientist” not an umbrella term for many fields? I personally view engineers as scientists, too. (Engineering follows the same scientific process). I understand your point, but to follow that logic, we should also talk about the construction workers so we don’t cause offence.

      Also, do have a way to correlate happiness to their reaction to your criticism?
      Do you have a standardized way of criticizing their shoes?
