AI Thread Summary
A pressure cooker operates by creating an environment of 1 atm above normal atmospheric pressure, allowing water to boil at 121 degrees Celsius instead of the standard boiling point. This increase in pressure raises the boiling point of water, enabling faster cooking. The discussion emphasizes the importance of critical thinking in understanding concepts like pressure and temperature. Participants acknowledge the value of self-questioning and arriving at answers independently. Overall, the conversation highlights the significance of clarity in questioning and understanding scientific principles.

Okay so if 1 atm is the pressure in our natural surroundings (I know it depends on altitude, but humor me, ummkay?), and 1 atm = 15 psi, then why does a pressure cooker get water to boil at 121 degrees Celsius. I mean the pressures are the same. How does a pressure cooker allow it to get hotter?

Nevermind. I just found out it's 1 atm above normal atmospheric pressure. Place palm to face emoticon here. Sorry.
 
A critical thinker continuously poses their own good questions, then answers them.

A sloppy thinker is unable to post a clear question and so must wait for another to work out what the question should have been, when the answer becomes immediately obvious.

aclark609; Congratulations on your critical thinking, you will go far.

Thank You! I did not expect to get acclaimed for this lol.
 

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
