Lecture v. Crash Course

[Kiana Rogers 1E]

I was watching a Crash Course video about Heisenberg's Uncertainty Equation on YouTube, and it gives the equation ΔxΔp≈h/4π rather than ΔxΔp≥h/4π that was given in the lecture. Is there a difference?

[Autumn Jackson Dis 1J]

Both are saying that the uncertainty is not exact, but in the first symbol it simply means "about", and in the second its still not exact, but the value of uncertainty has to be greater than a certain number. The second is more specific, you should probably use that one.

I would probably stick to the second equation, because that was the one Dr. Lavelle gave us in lecture, and most likely the problems on his test will depend on that formula.

I would follow the formula that Professor Lavelle gave us. I'm sure the midterm questions will be based around the formula he gave us, so I wouldn't leave it up to chance.
