Ok, so here is one way to do it that gets rid of the straddling assumption. But it does not get rid of the same orientation assumption. If the triangle sides are a,b,c. The number of rectangles that can fit would be \Sigma_{n=1} \downarrow\frac{d_{n}}{R_{2}} where d_n = a - (...

What do you mean by "straddle t2"? Thanks for the input!

Ive come up with this so far. It only allows to fit the rectangles in portrait or landscape mode, not a combination of both, nor diagonally. Any triangle can be made into two right triangles (I think). A given right triangle has bases t1,t2, and hypotenuse t3. The number of rectangles...

Does anyone know how one could calculate the maximum number of whole rectangles that can fit into a triangle. Say you know the length of the sides of the triangle (t1,t2,t3) and the of the sides of the rectangle (r1,r2). Thanks.

Hello, Using Yahoo Pipes it is possible to quite easily extract the location data from the XML feed of a public Google calendar and GeoTag it on to a map automatically (see http://pipes.yahoo.com/pipes/pipe.info?_id=d696db6de1dda5c86fc8fa59bbef6aec ) I am trying to create a version of...

hmmmm I read about the Wu experiment with the cobalt 60 carbon molecule decaying and emitting an electrons in the opposite direction of its spin. I don't understand why this is evidence for parity violations. It seems that if you mirror this experiment you will get the same image in the mirror...

thanks

And this is basically determined by experiment for different particles? Thanks.

Im trying to understand parity in the Standard Model. Ive read that quarks have positive parity. However I thought that the reason electrons have negative parity is because of the a symmetry of their wave functions, and this is what defines them as fermions. Quarks are fermions as well as I...

Ok. Just thought that since its undergrad level question...but ill ask a moderator. thanks

Anyone know why I am getting no answer for this one? Should I post it in the beyond the standard model forum? Cheers.

Fashioned after the derivation of the equation of motion for a string with Neumann b.c in Zwiebach's a first course of string theory, I have derived the very similar equation using Dirchlet b.c. My result, in natural units, is X^{\mu}(\tau,\sigma)=X_{0}^{\mu}-2\alpha' p^{\mu}\sigma +\sum_{n\ne...

would be nice to have an answer to this question...I would be very interested to see how alpha prime is derived.

Thanks. I need to look further into the 5-D metric proposed by Klein for the unification of EM and gravity and how that worked - any ideas for a good source for that? a review article or something of the sort... thanks again.

oh ok. now I think I really do understand. Source of confusion: hypothetical triple stern-gerlach experiment which exhibits that taking a measurement of Sx on an Sz eigenstate beam would produce 2 more beams in eigenstates of Sx. Obviously 2 resulting beams in the up and down eigenstates of Sx...
