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
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
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.
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.
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.
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.
3:55 And those types of hypotheses existed man... 4:22 OOOOHHHH So that's what observation truly means!!! It's about things you can detect. No wonder it was troublesome for people to believe in microorganism, and since you count of what you can detect and "what you don't see kills you" not having more information can really mess up your conclusion. And we didn't even mention cognitive bias.

Don't forget that a theory is a tried and tested hypothesis...

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 HAVE A QUESTION
if your hypotheses doesn't work do you try again
Sal you're a really genuine nad passionate being ...
jzk Allah khayr👍 thank you for this professional explanation!
Here are your notes
1) Observation
2) ask questions-why?
3) testable explanation(hypothesis)
4) prediction
5) test
6) refine/liberate
The last word is "iterate"
Experimental Prediction: I go and find Cairo on a map, it will not be in Iraq.
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.
If that puppy isn't dead, then he's probably retired by now.
Cairo is in Egypt....the content is so on point. Understood more than when I was in class🤝..thank you
thank you so much
Professor Khan been getting me through my assignments since preschool bruh I swearz kappa kappa 123
what software do you use to make your videos?
Very good video.
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
Thank you Sal Khan!
Great explanation, thank you
Actually both are equally plausible hypothesis until Is disproven by observation. That's the point of the scientific method.
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.
observation, reasoning, testing?

Very good
Is anyone here in SomersetAcademy?
is this textbook or is this how you personally conduct your experiments?

Thank you, gracia's.
Is this muted for any of you?
What series is this from?
Thank you.
Can this be a good hypothesis?: Ocean is larger compared to pond, that is why it freezes at lower temperature.
good job i like this make more science video i have a oaa test on monday

Okay but I love that he doesn't edit out his mistakes. He's just like, "whoops. Not 'satt.'" Yes sir.
really helpful
I don't have any sound when listening to this? Is it supposed to be like that or ?
no its not. or is it?
