NUMBERPHILE

Videos by Brady Haran

"As usual, in science in general, and in mathematics in particular, sometimes if you take a good point of view, everything becomes clean and amusing, but if you take the wrong point of view, everything becomes ugly and really painful."

I want to imagine this man teaches in bare feet on the floor all the time, while constantly spouting quippy one-liners like this.

[Harlequin]

I would like to see more of this gentleman and his pieces of paper please!

[oscarbarda]

This man is one of the most amazing numberphile presenters !

[gimpdoctor]

"this is most disappointingly interesting, ... or is it interestingly disappointing?" I chuckled at his pause to do a quick analysis of linguistic commutativity!

[timjones]

"You're not breaking any rules?" "Well, who knows?" I love that

[heoTheo]

kind of poetic that two the same loops will split apart and two opposites will interlock and form two hearts. :P

[NikolajLepka]

What I found to be perhaps more interesting, is that cutting the one with two of the same chirality rendered one loop consisting of 2 heart bottoms, and the other consisting of 2 heart tops

[VerticalSandwich]

This guy is fantastic. More of him, please.

[xisumavoid]

Is there a part 3? Also this guy is ace :-) Keeps it very interesting while explaining
EDIT: Is the answer that although it is a symmetrical shape it has an "outside" and "inside" so to speak, when split the produce different shapes?

Man maths would have been a lot more fun if we did pracs like this.

[festusmaximus]

straight from hearts to handcuffs <3

OMG - tho this body is now 62, my whole life may well have been different had this man been one of my maths teachers, earlier on. Such clarity, simplicity - just amazing!!

He's somehow more "present" than most people/teachers/presenters - not getting ahead of himself - no eagerness to just cut to the chase, get to the end result. He's somehow able to stay with us - to be aware of our presence, almost. His perspective is not just his, but _ours_, as well. Awesome stuff - Love this guy!!
~♥~

[Mornys]

I'm loving these videos, but I'm afraid they've put my brain in a knot I have no idea how to unfold. And please don't say take scissors and cut it in half.

[ujxtmap]

I was giggling and smiling all the way through these videos like a four year old kid watching magic. This was awesome! I would love to see more of Dr. Tadashi's in these videos. This man is brilliant!

[NeatNit]

It feels like there's more to this - he didn't even finish the thought...

[BubuSnow]

Watching those paper videos makes me understand why so many mathematicians are into topology!

[SuperValcron]

Anyone else notice the final cut of same chirality produces the top halves of the hearts together, and the bottom halves together?

[clairespivak]

Tadashi Tokieda's voice is amazing and i could listen for ages

[HL]

He just performed a shenanigan in front of everyone.
