64 = 65 ?

Could it?

It could...

SPOILER ALERT!

The 5x13 diagram is fraudulent. Blue and Red (or Green and Orange) do not a true triangle make - ie BlueRed is not mathematically similar to Red. Proof by trig if you're bothered, or alternatively just compare the ratios of the relevant triangle sides (2/5 vs 3/8).

The areas of each respective shape do still add up to 64 of course, the extra bit comes from a sliver of area along the opposite corners - you can see it most by looking at the bit between Red and Green.

All credit goes to Johnny Ball by the way. He was (and still is) my hero. In fact I don't think I'd have been a mathematician if it wasn't for him.

Think Johnny Ball was a bit before my time, it's all about the Singh for me, Simon Singh that is.

Another one? 2=1

Of Fermat and Big Bang? Humph you youngsters and your mathematical pop-idols :(

And the only good bit about that video is the comments thread after :D

They should make Johnny Ball required reading you know.

What, Johnny Ball didn't teach you how to prove that one? :P

Simon Singh is my idol, indeed. He should teach maths(/physics/science) to Britain I say, y'know. Forget training teachers, put Singh up on a large screen and he will solve Britain's maths problem.

Or alternatively bring up a new breed of mathematicians who find inane tricks like "64=65" and "1=2" so amazingly thrilling :)

I'll have you know such mathematical problems are profoundly philosophical. It teaches us not only nothing is as it appears but it encourages an inquisitive mind. Such a breed would be welcomed I would imagine.
















:P

Mathematician: 64=65? hmm need to work out why that's the case. Guys quit the singing(http://thethingaboutthisis.blogspot.com/2007/11/finite-simple-group-of-order-two.html), we have a mystery to solve!!

Engineer: 64=65? 2% error, who cares.

Finite Simple Group (of Order Two)

This is hilarious and completely geniusesque!! Sadly, this may mostly appeal to mathematicians but even if you don't get the mathness of it, it is still a great tune! :) Enjoy! Update: After having listened to it quite a few times I have to say I find it rather romantic. Yes, romantic... Finite Simple Group (of Order Two) by The Klein Four Group The path of love is never smooth But mine's continuous for you You're the upper bound in the chains of my heart You're my Axiom of Choice, you know it's true But lately our relation's not so well-defined And I just can't function without you I'll prove my proposition and I'm sure you'll find We're a finite simple group of order two I'm losing my identity I'm getting tensor every day And without loss of generality I will assume that you feel the same way Since every time I see you, you just quotient out The faithful image that I map into But when we're...

ye jo Jeff Buckley hai...

Jeff Buckley's cover of Nusrat Fateh Ali Khan's - Yeh Jo Halka Halka Saroor Hai from the album 'Live at Sin-é' The title song is a bit hard to translate but it's something on the lines of 'that ecstasy feeling' - terrible translation. I suggest you learn Urdu but for now here is a little breakdown: [Yeh Jo = that is, it is; Halka Halka = (very) light/little/slight; Saroor = exhilaration/ecstasy, Hai = is] Here is a link to the original by the ustaad : Link Below is an interview by the late great Jeff Buckley with the late great Nusrat Fateh Ali Khan for the Interview magazine (Jan 1996): Pakistani Qawwali singer Nusrat Fateh Ali Khan drives people wild with his music, which is an unbelievable combination of rich, soaring, complex sounds including something that is hard to describe but reminds us of yodeling. His music has been featured on movie soundtracks and in concert halls around the world, and his ecstatic voice haunts all who hear i...

What Dreams?

Where Three Dreams Cross: 150 Years of Photography from India, Pakistan and Bangladesh is the current exhibition at the Whitechapel Art Gallery . It claims to depict 150 years of photography from the subcontinent, of its people by its people. The exhibition is in most parts is not trying to show great photography but how photography has developed in the three countries. Walking through the gallery it made uncomfortable viewing. It felt like yet another exhibition displaying of the other . In this case, watching how the other uses the camera. Although, this show was curated by Asian artists it did not feel as though their talents shone. Most of the photographs looked like home albums that many of us Asians possess. There was nothing spectacular about them; what’s so fascinating about family albums of Southasian origin? So there were portraits of some political leaders like Jinnah, Nehru, Gandhi etc. There were also, some bollywood and lollywood posters and photograph...
