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.

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

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.

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.
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.
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.
I need 1 question for the narrator 2 things that you are lukewarm on and you want to explore future 3 thing you find interesting understand. If any one could respond with that I would rlly appreciate it
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
A lot of people, even scientists tend to forget the most important part that science is also done for other people to build upon, and some might keep an eye closed toward mysticism for the sake of being "open-minded" and "probably turn out right 100 years from now". The moment they start thinking that way, the very building becomes shaky from their floor up, and will come down on their asses way before that 100 year expectation.

Can you back that up with some science/research textbook reference?

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 ocean water does not have the same salt as table salt, why not take from the pond and ocean respectively?
It's already known it's the same salt. Mixed in impurities give slight coloration sometimes. But salt in kitchen is same as salt in the ocean.
