Superstrings (10/10)

Beautiful series! It's a delight to listen to Prof. Russell Stannard ;-)

An excellent, delightful, and eloquent discover-er.

Ooh! I so wanted you to eat that dohnut! : D

nice ending hahaa

@Stibaable: a sphere is an "entity", not a set of points. It would be needed an infinite number of points to represent a sphere. while the sphere is not infinite. So, I believe that the best way to go in order to better understand the mechanics of the universe is thinking of superposition of "modes" of movement. And I cannot say more, otherwise you write the article before me :). Stay good, without any resentments.

@feliztex

I appologize if my first response was seen as an insult. You have got an innovative view of mechanics, thumbs up! I hope your article will be well received.

[feliztex]

@Stibaable: first you seem to laugh about what I said. I see on that a subtle insult that absolutely mus not be allowed in science. Then you may have thought a bit more in what I said. Then you ask me to explain better? This is not a class room. Here you have no rights to the opinions of other people before you understand you have the duty of treat them well. But ok, since you seem to be young I will tell you just this about my opinion on mechanics: shapes is what meters, not points in space.

[feliztex]

@Stibaable: waw, you already know the term "linear algebra" kid. Did you already finish your graduation? But at least you could a bit reach that "my" r can be a generalised coordinate... go to study a bit of Hamiltonian mechanics and then appear again to bring us your valuable advices. Either that or wait some years more to grow up.

[Stibaable]

@feliztex : Could you explain your views more clearly and without personal insults? I would appreciate that. Ok so your r is a generalized coordinate. Why would generalized coordinates constitu additional dimensions?In my view GC are only simplifications which take advantage sometimes of constraints to enable us to simplify a particular mechanical problem. In Hamiltonian mechanics there is defined a phase space which has 6 dimensions (x,y,z,Px,Py,Pz), again you could take any number GC....

[Stibaable]

@feliztex: to describe the behaviour of the system relative to some reference point. But in my opinion these are not aditional dimensions because you could describe this motion in a normal coordinate system (x,y,z,PX,PY,PZ) it just a matter of convenience to use GC. I am not saying that my view is the correct one or that my advice is "valuable", so please explain more about your views and yes I am an undergraduate student of astrophysics so I had studied alot of analytical mechanics.

[feliztex]

Can the 6th dimension be r = sqr(x1² + x2² + x3²) ?

[Stibaable]

@feliztex

I think not. Why would distance (euclidean) be a dimension? Does it tell where a point is in space? -> No, so it is not a dimension. Your r can be a dimension in a spherical coordinate system where the coordinates are r, fi and theta. If you are interested in the subject I sugest you start studying a branch of mathematics called linear algebra.

thanks

[TheLivirus]

Awesome series! I was nailed to the monitor :)

[mrooster09]

hahaha doughnuts!!haha, mmmm this man knows wassup!!

[blenderpanzi]

Now I want to eat a doughnut.

[SebastianGeffen]

... so this isn't van halen?

[miamifan2191]

thank you for these i found them very relaxing and informative, i hope to see more

[theflashg0rd0nator]

doughnuts are my universe! :)

[Films4You]

Stop eatting the Strings... LOL Brilliant information
