I know this is an old post but I would also like to build a Mach-Zender interferometer. did you build one and if so how did it go.
I made a simple Michelson interferometer and got some nice fringes with a cheap dollar store laser pointer. I tried rearranging it tonight by adding a...
we solved the condensation problem by using a 80,000 BTU propane forced air heater. I rearranged some of the power runs and made some more headroom on our backstage circuit. the fan on it only draws 1.5 amps continuous and if it does trip the breaker we won't lose any of the sound or lighting...
As I'm not an expert in anything feel free to completely disregard any and all parts of my comment. I voted other in the poll for the following reason.
I personally believe that lift is generated via the boundary layer effect. (and that bernoulli's work is among the earliest experimental...
the barrel with water I put under the stage didnt keep that section dry. I'm really disappointed about that. this morning I found an anti slip paint additive made from crushed walnut shell at a local paint store. I'm going to mix that in with the outdoor latex paint I'm using. Its not nearly as...
@russ_watters the audio amplifiers and Rf rack are under the stage, the section of stage directly above them does stay slightly dryer, but not by much . and if you want to come for a show I am in sonoma county CA and we have 3 more weekends of shows this season. you can come to a show wether or...
Im on the tech team doing an outdoor concert series. I have a dance show coming up this weekend and I am having a hard time keeping the stage dry. Its a nice big black stage radiating its heat away at night and around 9 pm it starts to get a bit wet and slippery (very no bueno for dancers) I...
Thats exactly what i thought i had said. or i least i hoped that's what would be understood. what makes infinity not a maximum? by the strictest use of the word, maximum does imply a limit. in my mind with any real system entropy is going to be closer to infinity then zero (infinitely closer)...
"the energy of the world is constant; the entropy of the world strives toward a maximum"

i'm sure you can find, as i have found multiple textbooks, both old and new, that have the exact phrase entropy strives towards a maximum. so don't start a war over semantics when you knew what i...
I am interested in finding as many unit less representations of the second law of thermodynamics as possible. other then gravity, it is the physical law that we experience most in daily life. to greater or lesser extents it can used to describe everything that controls our existence. I'm looking...
what i am trying to make is similar to a shock absorber except that most shocks don't have any free movement, there probably are types of shocks that will dampen in on direction and move freely in the other but that not what I am going for. and springs won't work either as i want a constant...
I'm a machinist and i want to make a hydraulic circuit for a personal project. I'm sure the type of movement i want to make already exists i just don't know what it would be called. I want to make a bi directional movement that from a center postion encounters a constant resistance as it moves...
