Professor David Eisenbud talks about conics, and visits a few numbers along the way.

NUMBERPHILE

[MrPictor]

Eisenbud's uncertainty principle: when drawing circles, the location of the pen cannot be known with any accuracy whatsoever.

I love his D. Eisenbud's cadence and soft spoken-ness. It's always a pleasure when he's on Numberphile : )

Parker Squares and Eisenbud Circles. Can't wait to see what approximate value gets created on Numberphile next.

Joke reference for those unfamiliar with English-language culture: "1066 And All That" is a parody of History teaching in British primary schools, published in 1930.

"if you may remember i did a video of the fundamental theorem of algebra", yes it was 8 years ago and one of my favourite numberphile videos ever

[hufflepuffjoh]

Oh my, it's been so long since we had an Eisenbud video! So great to see him back

[rif]

"The point at infinity" - greatly appreciate the rigor! always surprised that other mathematicians on numberphile dont state it that way.

[QuantumHistorian]

Lovely topic! I can't help but feel that a little more explanation could be given to statements like _"A circle in the space of line, "_ not everyone watching numberphile is going to immediately see a parameter space as a geometric object.

when you combine complex numbers with conics on Numberphile you get an iConic video

[patrickmckinley]

11:50 What about the xy term? I don't understand why we're not dealing with a 6-dimensional space when conics are free to rotate.

[nokanol]

Off topic, but is a video about the singular aperiodic tiling (an "einstein") that was JUST discovered a few weeks ago in the pipelines? If so, I'm really looking forward to it!

[wyattstevens]

15:13 I was in a program co-hosted by Dr. Sotille (Dr. "I can make all 3264 conics have real values for a, b, c, d, *and* e") a few years back. I still remember that half an hour into each session of the program, when middle-school and high school students would split up, he'd just yell "HEY!" to catch everyone's attention. Seriously- I can still imagine him doing that, which is the first thing I thought of after you mentioned him! (and after I realized he was it- that made me do a double-take!)

7776 is called "weremeke" in Arammba, also "wärämäká" and "wermeke" in other Yam languages.

[redapplefour]

i just happened to watch the video on matrix factorization a couple hours ago, i always misread the title as matrix multiplication and thought it wouldn't be particularly interesting since i already understand all that.. lovely to see another one with david eisenbud already! saw a video too, on projective geometry, which is related to this video's topic somewhat too! definitely one of the most odd sub box moments ive had like that before, most i can think of right now

[Donbros]

I am actually impressed not by the video and theory but by how he drew those circles neatly

[CatInABaseballCap]

I once fell into a rabbithole of 3, 7, 9, 11, 13, and 37. I wasn’t disappointed.

[sparkie]

Man, the Numberphile animations have come a long way...

[wiserhinoceros]

Loved this - such a clear explanation of ideas in Algebraic Geometry!

[bhardwajsatyam]

At 15:32, "Sottile" turns to "Sotille" for a few frames!

[subjectline]

The 1066 and all that reference is very much in keeping with the Eisenbud style.
