I think like many others said, C++ is a great language to start off with. It is an Object Oriented Programming Language, which makes it very special and convienient to work with. Once you get a hang of C++, you could move to any other language, say Java, or Visual Basic, with are very similar...

Nice Idea! I too thought of converting Mechanical Energy to Electrical Energy, therby powering my motor bike with the electrical energy. Sounds great! I'll see what I can do. And I'll update you on my progress. Thank You!

But each car battery weighs roughly 20 lbs... and 4 such batteries will weigh about 80 lbs. That's a little too much weight... any alternative?

Hi! I thought of motorizing my 2 wheeler. 1) Now i want to know how much Voltage (DC motor) is required to turn my wheel. 2) The source of energy? (Maybe Electric). If electric, I know it will be difficult to use batteries to run the motor. Considering car batteries, they are just too...

Thank you bobc2! Its my pleasure!:)

Right guys, that makes a lot of sense! And nasu, what exactly was this project conducted by IBM Zurich? Can you please elaborate a bit on it? Thank you.

Not sure. The answer will be a variable, and my assumption is that a MAJOR part of the energy is not re-absorbed .

>>@cmb Now, an "isolated system", here, means there is no EXTERNAL application of ENRGY on the atom. According to my understanding, the answer to this is yes(paritally). But an atom cannot absorb all of the energy, it emits. Hence, while majority of the energy is emitted, there is some...

Hi, Its all out of curiosity! Are'nt you curious to know how the Universe began? It might not be of much relevence to the general public, but in the hands of scientists, it can be used as a tool to understand the universe better, our Earth better and infact even understand the...

Linear Algebra - Deals with equations and transformations, all in one variable Vector Calculus - Deals with Calculus in 3D. - Its nothing but multivariable calculus! and you are never going to find Schrodinger eqn derivation in a math book. Look for it in a Post Grad's Physics book. or...

Right! and what about the future of CDs with the entry of Blue Ray discs. I understand that Violet light is used to read the CDs, instead of the exisisting Red light. Red light has a higher frequency, and shorter wavelength, than Violet light, that makes it faster. Its obvious that Velocity...

No. (Lymann series - From n=2 to ground state(n=1)) We will not be able to see a constant emission of 2eV, but that's because there is energy both being absorbed and emitted(considering the atom is not isolated) and this amt of energy that is released/absorbed varies again according your...

Right! This was what i found on the website: "...Using high resolution optical scanning equipment..." But my question was, why not use sound to read discs, rather than LASERS. I agree LASER is monochromatic. Therefore, it does not get dispersed. And as Wolfgang2b pointed out, there is this...

>>@cmb Right! That makes sense. What you are saying is perfectly right, when the atom is isolated. There will be quantum fluctuations, that will not cause a higher transition. But that is'nt really the case, right? there is always some external energy acting on the atom, that could excite...

>>@cmb okay cmb, now put forward your question. My answer to the original question: Can an electron move to a higher energy level on a permanent basis?, is no. Its impossible to stay at a higher energy level permanently, given that: 1) Electrons are most stable in their ground state 2)...
