Sexy prime numbers

[Eran of Arcadia]

So just like a 2D piece of string, if viewed from just one dimension, is only a particle or point, and becomes a string with another dimension, is that is? Because I can grasp that.

The strings are 10 or 11-dimensionsal, and ripples on the string interacting in 10 or 11 more dimensions are seen as particles in our 4-dimensional spacetime.

Actually my father (who loves mathematics) has a proven theory about prime numbers, which relates to this "sexy" prime numbers! Though he never called them sexy....

This thread is funny!

There are quite a lot of amusing gene names out there. Since discoverers can often call it whatever they want. Which invitably leads to amusing moments when dignified old scientists give presentations on them .

Some of the best -
Fruit flies
cheap date gene (flys unusally sensitive to alcohol)
pray for elves gene (the person writing up the gene annotation was up late and seeing things. seriously)
kojak gene (flies lack bristles)
ken and barbie gene (flies lack external genitalia)

Human
Tigger gene (can jump to other places in the genome)
sonic hedgehog gene (yes it is named after the computer game)

Arabidopsis (plant)
superman gene (has extra stamens (male genitals))
clark kent gene (another form of superman)
kryptonite gene (represses superman)

and of course there is the ARSE gene, and the abreviation of the influenza fuculokinase gene is blocked by the profanity filters .

Many genes are named after what go wrong when they're disabled. Thus, one of the critical genes for eye development is called eyeless.

First, I give you sexy prime numbers. One can't help but admire the mathematician J.K. Andersen for writing a paper titled "Gigantic Sexy and Cousin Primes."

Thus guy must be a real geek to think some numbers are sexy.

x^7 is a polynomial whose roots can be found using only algebraic operations. Send the Fields Medal to the University of Ottawa, care of pboily.

Seriously, the big deal with polynomials of degree > 4 is that there is no general "algebraic" way that will allow you to find the roots of all such polynomials (thank you, Abel and Galois). But you may still find the roots of particular polynomials using only algebraic operations.

I apologise, thanks for clearing that up, I did mean in general, I remember seeing some equations for the Quartics though and I was referring to those, very complex although I guess being at such an early stage of learning, the simple to you appears complex to me.

When I saw the thread title, of course, my first thought was that 69 is not a prime number.

I thought of the same thing.

... although I guess being at such an early stage of learning, the simple to you appears complex to me...

You'd be surprised how often the simple appears complex to me as well.
