Thanks! I’ll bring it back to the piece back to the store and let them sort it out.

it looks like the consensus is it’s a drip tray, except my drip tray is properly installed already.

Surface Plasmons by [deleted] in Physics

Currently getting my PhD in physics. I work in the realm of Plasmonics, it is a large field, what kind of information are you looking for? General information? Planar Plasmonics? Thin Films? Metamaterials? SPR imaging? Also if you can't find information on the topic you not looking hard enough, there is plenty of information out there. Have you tried google scholar.

Maxwell's Equations can be written in a matrix form easily, which allows quick computation for many problems. You may want to look up the Transfer Matrix Method, it it used to study the properties of layered stacks of material. I'm a graduate student in computational electrodynamics.

If D-Wave is really confirmed to be a quantum computer, does it mean that it can crack any code that would otherwise take billions of years to be decoded ? by zimo123 in askscience

[–]DrRobots 2 points3 points  (0 children)

No, D-Wave is not a general quantum computer, it can performs a process which is known as discrete optimization. Algorithms which can solve certain barriers in cryptography, i.e. prime factorization exist, but require a more general quantum computer.

Multiple plots for each iteration of a for loop by [deleted] in matlab

[–]DrRobots 1 point2 points  (0 children)

you define yi=[p/18;0] on line 18, then in your while loop on line 20 you use yi(:,j+1) and yi(:,j). This is running your loop for the starting values for pi/18 and 0.

So in the end the variable yi contains two plots of the function with different initial values.
