hutchphd replied to the thread I Topic about physics axioms, theory, laws etc...'s I think Galileo gets the credit for this technique. Newton was born with a year of Galileo's death so he knew of the work I would... -
hutchphd reacted to Dale's post in the thread I Topic about physics axioms, theory, laws etc.. with
Like.
That was from experiment. Now, we consider those experiments so reliable that we have incorporated it into our definition of force... -
hutchphd replied to the thread Geometry: Similar Shapes.Let me add to the clutter to re-emphasize: If you make an assumption and it leads to a valid solution, that does not invalidate the...

hutchphd replied to the thread Geometry: Similar Shapes.it has so much more pizzazz than "guess", don't you think....?

Maybe give L2 further maths a go first. It will set you up well for A level.

Given that there are two different values of x, it would be impossible to draw the triangles to scale in this problem, as if you drew...

hutchphd replied to the thread Geometry: Similar Shapes.But using that symbol in the "official" drawing would be a lie. It so happens that the assumption of || does lead to a valid solution...

Totally 110% agree. Engineering is a completely different animal. Absolutely. In engineering, two lines can be parallel if they are...

Not to mention that the problem explicitly says there are two solutions. If the student finds one solution and stops there, they have...

hutchphd replied to the thread Geometry: Similar Shapes.I was not teaching a course in geometry, but engineering physics. Including a diagram that tries to misrepresent the discription seems...

hutchphd replied to the thread Geometry: Similar Shapes.My problem with this pedagogy is that my first admonition as a teacher was to "draw a rough diagram". This was engendered by my getting...

hutchphd replied to the thread Geometry: Similar Shapes.And that purpose seems to me to be malicious. Is this a restatement of the parental admonition to "do as I say, not as I do": "do as I...
