Although I am a novice and I couldn't follow your words exactly, I will keep this in mind. Thank you for the advice.

You are implying that studying AVR textbook is not really good choice? So it is good to learn mechatronics and AVR datasheet can suffice?

I'm looking for some textbook for learning microcontroller(MCU), especially AVR, Atmega series. Does the electrical and computer engineering department in some university teach this devices? If so, what is the basic textbook for university students to learn MCU?

So, I understand that the gate can be viewed as combination of 0 and 1 for 4 binary digits by using 0, A, B, 1. But how do you make 1 by XOR??

Below is the extraction from quantum computer book, but I think my question is related to classical computing; "Now let us generalize from one to multiple qubits. Figure 1.6 shows five notable multiple bit classical gates, the AND, OR, XOR (exclusive-OR ), NAND and NOR gates. An important...

I see... Thank you very much. Now I understand.

I'm confused. trivial = single input? wiktionary says There are six non-trivial, symmetric, two-input, Boolean logic gates: AND, OR, XOR, NAND, NOR and XNOR. but these logic gates mentioned above are not single input gates. how do I distinguish that with The only non-trivial member of this...

My question seems like it should be posted in Computer Engineering section, but below is how I found this word. I was reading the textbook: Quantum Computation And Quantum Information - by Michael A. Nielsen and Issac L. Chuang. and I came across with the this word; "1.3.1 Single qubit gates...

yes, that was what I meant. the type used for storing food. that left stain on the surface. dipping into the liquid... Are there any other candidate? latex, Isopropyl alcohol (stored in laboratory) Acetone (stored in laboratory) probably not acetone...

wrapping vinyls... I tried that before, but those wraps left really dirty (not dust) stain on the glass surface of the cube beam splitter... not a good idea...

someone purchased cube beam splitter years ago, it was wrapped around in tracing paper, really delicately. I un-wrapped it , and used it for my experiment. Now, my experiment is done, and I don't know how to store it safely. If I leave it on the shelf carelessly, the beamsplitter will get...

If you solve the Schrodinger Equation, you will get solution for the equation, which is orbital. My question is, for example, dumbbell-shaped p-orbitals in hydrogen atoms or other atoms, is there some expert who visualized this orbitals and confirmed experimentally? And how can it be...

I just started my Physics Forum account. I am interested in quantum physics, electrodynamics.
