Many here may not be familiar with a hero of mine - Alvin Toffler. Toffler is a futurist who is known best for his two books, Future Shock, and The Third Wave, both of which influenced me greatly. In fact to a certain extent it is true that my own business is modeled on "the electronic cottage"...

Mars is likely to be the first planet that we might decide to terraforum. Problems with Mars is its low atmosphere and cold temperatures. I have seen many strange concepts for terraforuming Mars. Like nuking Mars (not a good idea) to building factories to pump out green house gases...

I was assigned this problem from my physics teacher, but it doesn't really make sense. I would ask the teacher, but I don't go back to class for a few days. At this point, I just need help trying to understand what the problem is asking for. Thanks very much in advance for any help. Find the...

Any ideas for a good Rube Goldberg Machine anyone?

Greetings, I've never liked the idea of Quintessence (although I admit I don't understand it fully). 1. As for Dark energy, what are the leading theories on how it may be caused? 2. Also, I have an idea about a possible cause for the Universe's acceleration. Perhaps, the fringes of the...

:confused: Hey ya, I need to design 3 different experiments to find the specific heat capacity of a metal block. I have got 2 but am just stuck for a third. The two i have are: Method of mixtures Heat up metal block in a water math, transfer to a cold water bath and observe the temperature...

Hey, I'm having a bit of difficulty with a specific problem. I was able to somewhat easily work the problem out, but the few different answers I've tried have been incorrect. I'm beginning to think there's something wrong with my trigonometry or something because I swear the calculus is...

allright so I'm constructing a rube goldberg device as a side physics independent project and it has to go through ten steps to achieve the final outcome of lighting a bulb. i need some ideas for steps I'm drawin a blank. it has to go through 5 different energy changes like potential, kinetic...

Stefan Rosswog has some ideas about what causes GRB (gammaray bursts) He and Daniel Price have a recent article in Science journal about it, and they have some stunning movies of two neutronstars spiraling into merge. I could not find the Science article---the most recent Rosswog---online. It...

i know there is a big link for science fair ideas somewhere, i cannot seem to find i though, could someone redirect me at the least, or perhaps post your own ideas here?

Hey, I am supposed to do a senior project over any subject so I decided why not do it on something I love, Physics. My only problem is I don't really have any good ideas for what my project should be based on. I thought about doing the unrealistic aspects of movies that are based on physics...

Hello everyone! I'm stuck on this problem! as usual. Find a particular solution to y'' + 4 y' + 4 y = 6.5 e^{-2 t}. Here is my work: y''+4y'+4y = 6.5e^(-2t) r^2+4r+4 = 0; r = -2, repeated root So i made the guess: y = A*t^2*e^(-2t); y' = A(2t*e^(-2t) + t^2(-2)*e^(-2t)) y'' =...

Alright, so I need something really good to do with my gf for valentines day. I've thought of the usual, nice dinner at a nice restaurant, but I want something really special. Also, any ideas for gifts?

hi, I'm in the AP Physics for high school, and I've been wondering about an idea about constructing a lab... i need some things i can test, because the assignment is to create a lab on your own w/e it is... (kinematics, thermo, w/e AS LONG AS it's not electrical or uses wires)... any suggestions...

I need ideas for a physics project. The teacher said that we could do anything, so long as we can get hold of the equipment for it. I basically need to answer a question or have some kind of title which I could investigate, for example, drag forces on different shape objects, variation of...

Hi string group, I'm a new member. In a few months I'll have completed my final exams and can finally start to write my diploma thesis (german diploma) in theoretical physics and mathematics. Naturally I'm a novice in the subject, having only very superficial basic knowledge from a...

Hello everyone, I'm having troubles figuring out this problem. The directions say: It is easy to check that for any value of c, the function y = ce^{-2x} + e^{-x} is solution of equation y' + 2y = e^{-x}. Find the value of c for which the solution satisfies the initial condition y(3)= 8...

Hi everybody. I'm going on a date with a girl tomorrow, I need some Ideas. We agreed that we both wanted something non-traditional, that means no movies. What unique ideas can you come up with?

I've entered the science fair this year and my physics teacher would like the class to do a project relating to physics. I was wondering if anyone had any ideas that would completely blow away my teacher and the judges at the science fair. Something possible to do that is. Any ideas??

My chem and calculus teachers are both turning 50 this year, so we are planning a party for both. I just wanted good ideas for gifts that relate to what they teach. And I'd rather have good gifts than cheap gifts (They are really cool, and a bunch of ppl are helping to pay for it). Any...

Hey all, quick question here. I'm doing my first year of ee at college right now, and while some of the classes I'm taking (physics etc) are helping me very much to understand some of the topics, I'm getting extremely eager to practice some circuit design (my first circuit design class won't be...

Heya, The seniour mathematics teacher at my school has given me (and a few others) the task of designing a 'Math Fun Day'; an event in which about 200 crazy 12-13 year olds visit our science and mathematics school to participate in mathematical activities/games. We're running short on...

I really like programming 3D games in C++/OpenGL. I've been doing it for years and I've gotten pretty good. Now I just finished a game and I'm looking for good ideas for my next one. To pass my time I tried to create coordinated AI movement around obsticles, that works pretty good but it...

Ok, so I want to integrate a general function defined by an infinite product, and let us assume that the product is nice (e.g., absolutely convergent, ect.). So, without expanding into an infinite sum, how do I evaluate \int_{z=a}^{b}\left(\prod_{n=0}^{\infty}(1+f_{n}(z))\right) dz Let z...

What are some scientific ideas you think had the greatest impact on society? It'd be nice to have a few that aren't "obvious." (don't mention the transistor :-p)

I'm not sure how I always get roped into these things...but again I turn to you, my faithful science friends, for your creativity & imagination! The Chemistry Society at my school is getting club t-shirts again this year. Being an all girls school, last year's shirt read: "What do you need...
