Fluid Mosaic Yes, the problem is that the word 'theory' used is everyday language has a different definition from scientific 'theory'. So, it is understandable that people are mistaken with that distinction.
Just checked Oxford and Macmillan dictionaries. That's not the definition they have though. Here's the definition from Oxford: A supposition or a system of ideas intended to explain something, especially one based on general principles independent of the thing to be explained. I think the part "especially one based on general principles independent of the thing to be explained" is what seems to be the difference between a hypothesis and a theory. At least, that's the impression I get when I read the definitions of both the words in Oxford.

The example with the "Why does the ocean freeze at a lower temperature" was because of salts and minerals in the ocean, and is the same reason why salt water boils at a higher temperature than normal.
Alhazen's quote is essentially justification for why everyone should be a contrarian even to themselves. A lesson that the press and populace in the US desperately needs to learn.
You sound like my Teacher. I like your channel and thank you for everything you did for students around the world. Thank you very much. I am writing notes about the scientific method
POV: You are a high school science teacher, have assigned this to your students (especially Biology students during quarantine) and now you are watching this as part of your Doctoral Class. (don't worry kids... this video is not going away)
Excellent! thank you very much for this brillant explanation and illustration about the subject of your lecture. this is not because I am an Arabic person and be proud of be Arabic and that Al Hassan Ibn Al Haytam, was also an Arabic scientific who was the first said about the importance of being skeptic and critical thinking; but because your presentation was clear and concise
Seeing all these commemts are about how Cairo isn't in Iraq, I can only conclude that these people are really bad listeners, that English isn't there first language or that they're hearing-impaired.
I think it would be a good idea to include a bad hypothesis after the fairy example that is less obvious and looks scientific and then to explain why that in fact is also a bad hypothesis
His hypothesis definition is incomplete. An hypothesis is not only testable, but it is also falsifiable. For example, an hypothesis that stated that the universe contained life forms other than life on earth is certainly testable to a certain degree, but it is essentially not falsifiable because the universe is so expansive that even if we never found life in the places that we looked, life could still be elsewhere in the universe.
I'm not seeing the connection between the scientific method and inductive reasoning. The process of gathering information sounds like making an observation post hoc, like deduction
According to recent PEW polls, average Americans significantly lag behind scientists in all areas of science. This means that the average American does not trust or have confidence in scientists that spent their lives devoted to education, working in their respective fields collecting and analyzing data and subjecting their findings to peer review in scientific journals. While the average American can't be expected to understand scientific data, formulas, equations, and complex analysis, I do believe they can learn to gain better trust in scientific findings by understanding basic concepts used in the scientific method, once they learn it. Just as important is the inability of the average American to discern among scientific and pseudoscientific information widely dispersed on the internet, modern advertisements, and published articles. So far, the scientific method is the best method I know of to develop critical thinking skills without the intent of criticizing an individual's world view or beliefs. At the same time, the Average American will learn the precise meanings of the vocabulary used in science, especially words like hypotheses, theory, evidence, natural laws, findings, verifiable methods, results, pseudoscience, peer review, etc., are used in published scientific findings. The amount of data being collected by scientists studying in every possible location on earth space, is far to for the average scientist to understand, let alone the average American. But, scientists do share an understanding in basic scientific methods, which the average American can learn and develop more confidence in too.
If tomorrow someone kick a ball and doesnt accelarate (the only force in a ball is from the kicker) , we will assume that 2nd law of Newton doesnt work or that the ball is massless?
thx for the answer so we somehow "believe" that these laws holds true right? for predictions we assume that our laws are true but these doesnt mean we have prove they are true
sry for the verb i wanted to say somehow we take as granted that these laws holds true...but how we define force from 2nd law of newtons , if force is defined as the cause of accelaration then our 2nd law is proved but this is absurdity..isnt force something like pull or repel ? we can define force through 2nd law but this is only because through induction we come up with the conlcusion that ΣF=ma is always true..sry if i tired you and sry for my bad english
You already knew that the fresh water froze because it has no salt. You already knew the salt water won't freeze. There must be some method for testing a situation when you don't already know the answer.

Don't forget that a theory is a tried and tested hypothesis...
A concept that a lot of people seem to struggle with.

Can you back that up with some science/research textbook reference?
Just checked Oxford and Macmillan dictionaries. That's not the definition they have though.
Here's the definition from Oxford: A supposition or a system of ideas intended to explain something, especially one based on general principles independent of the thing to be explained.

So true. The hypothesis is something that takes longer to develop. No one gets that. They seem to think they are one and the same.

i think we just know there is a force working on a body because acceleration. No acceleration = no resulting force.
thx for the answer so we somehow "believe" that these laws holds true right? for predictions we assume that our laws are true but these doesnt mean we have prove they are true
