DUDE! Stop Looking at the fucking display!!!!!!!!!!!
Great presentation.
the way he talks is quite boring. I am feeling sleepy.
Not a snoozefest at all…simple someone who is very good, presenting
something in a measured and deeper way than is usual. Something to be
understood and appreciated.
So true
The mathematics education in elementary and middle schools in the US are
problematic. I cannot image the professor is using such simple maths to
show its importance. What he is talking about is really the content of a
maths class of Grade 2 in elementary school in China. —– A graduate

“Problem solved, problem goes away…” Lolwut!?
Proof – as if any were needed, that mathematicians should not be allowed to
teach mathematics, let alone teach teachers. It is clear that he
understands what he is saying. And it is equally clear that he has no idea
how to explain what he understands to anyone who doesnt already understand
what he understands.
If you dont understand what i am saying, then you shouldn’t be a teacher
either.
For example, Jacob Bronowski WAS a good teacher – an excellent one – and in
his TV series The Ascent of Man he provides a constructive proof of
Pythagoras’ theorem – in all likelihood the proof of which Pythagoras
himself conceived – that absolutely everyone over the age of three can
understand.
This speaker’s proof presentation is a tortured version of that
constructive proof, presented in such a way as to make it look like magic,
which is by definition incomprehensible. The speaker clearly suffers from
that ego problem that so many mathematics teachers have: he thinks “Ha ha,
I’m smarter than you”, whereas in reality he is merely more autistic.
while i agree with the sentiment in this video strongly, i cant help but
say that i absolutely hate that proof as it offers very little understandng
of (why) the pythagorean theorem is true. I like this proof: (where “.” is
dot product, a and b are orthogonal vectors whose sum is the vector c)
c.c=(a+b).(a+b) |c||c| = a.a + a.b + b.a + b.b |c||c| = |a||a| +0 + 0
+|b||b|
Snoozefest
i don’t have a lot of back round in math in fact i suck but the way you
explained this to me i did understand it so Michael you are wrong! and you
have inspired me to learn more about math so thank you!……..
You probably like your way because that’s the way you like – no good
reason. Your way requires more Math foundation to be intact in a person
before that person is ready to understand your way. The presenters way
probably requires the least amount of Math foundation to be intact in a
person before they’re in a position to understand. I also strongly agree
with the sentiment — I think that’s the point of the presentation – not
how to prove the pyth. thm. btw 1/9 = .11111….. not .011111…..
he did it that way because vector arithmetic was created after the
pythagorean theorem.
