  1. is most work theoretical or is there a significant amount of experimental work going on as well? what applications does this knowledge have? do we know yet?
  2. ^so those are hot topics right now? interesting..i'll look them up thanks

    Eching

    here's a slightly different way to do it (pretty much the same though) print out ur circuit design on transparent paper...put the transparent paper onto the copper board and then shine an ultra violet light through for about 12 min (with the layout on top). Afer that, put it in some developer solution and water (warm i THINK...not 100% sure) the ratio is about 1 part developer to 5 parts water (1:5). Use a little sponge brush thing to help take off the resist. The water is to dilute the developer, be careful...if there is too much developer, your design might get ruined. After you see your design take it out and apply some acetone to the back (where there is no design) to take off the extra copper resist. Next...mix about 125 grams of sodium persulfate in about 0.5 L of water. Put this solution on a hot plate (i don't think it should be boiling though...just warm it up...maybe it should be boiling? just try it warm first). Use the little sponge brush thing to take off the remaining resist...all the copper should go away (except for your design) and there should be yellow showing through. little bubbles will appear so brush them with ur sponge brush. keep flipping the circuit board in the solution. after you're done apply some acetone to the front (side with the layout) and that should remove the remaining copper resist... hope that helps!
  4. I have recently been becoming interested in quantum chromodynamics and have been wondering what is the future of this field? what problems are currently being worked on? what areas are "hot" in this field?
  5. thanks for the advice...i'm really more interested in research/academia than starting my own business/corporate stuff. Engineering is about making things practical, using physics..but i'm more interested in discovering the physics that engineering uses. interesting that you mentioned the course in tokyo...and i'm actually in my 3rd year of japanese now lol
  6. i'm very interested in topics such as particle physics, quantum physics, dimensional physics, string theory etc. i am also interestd in engineering should i get an undergrad degree in engineering (EECS most likely) and then specialize in grad school? or do an applied physics/physics major in undergrad? what job oppurtunities are there if i don't go the engineering route (other than academia)? i think there are advantages doing engineering then specializing in the above stated branches of physics: you still get a physics background...you can do scientific instrument development, and computer science skills which are very important today, also more job oppurtunities (i think). any opinions? i also don't want to get SO specialized that there are no jobs lol
  7. hmm i successfully built a few of these lifters in 8th grade (i'm in 11th now). personally i don't think that they are true antigravity...but very cool nonetheless...perhaps i can dig up some old videos/pictures i can assist in further construction questions (if i can still remember everything =p) and you don't need to build the generator...i actually found one online that is perfect for the lifter i'll see if i can get the website name
  8. recently i have been interested in high speed particle acceleration/ quantum physics. i've just been reading sort of general articles in the area...but what are some really hot areas? what are some good scientific magazines to subscribe to? any interesting papers? i'm more interested in the experimental physics than the theoretical but anything is fine. I probably do not have enough mathematical experience but should have solid foundations in differential equations, linear algebra w/in the next year. btw i'm a high school student (11th grade) and am looking at doing research in this area. I am not asking for research topics, only guidance to hot/new areas in which more research needs to be done. i have a local lab in which this type of research is being done so i should be able to get access to the required resources. i've worked in labs before with mentors etc; been doing my own research (mainly comp sci and engineering) for the past few years. thanks!
