The data showed a linear relationship between voltage and current, corresponding to the equation with 1惟.In this experiment, we examined how the current flowing through a resistor varies with the voltage applied across it. Current is defined as the rate of flow of charge per unit time, and ...
some background or history to the area of research. It is very rare for an idea to arise by itself since there is always some precedent that has led to the ideas being tested in an experiment. It might also include some application of the principle behind the experiment. For example, ...

Physicists are excited about anyons not only because their discovery confirms decades of theoretical work, but also for practical reasons. For example, Anyons are at the heart of an effort by Microsoft to build a working quantum computer. This year brought two solid confirmations of the quasipartic...
Progress in science often happens when two or more fields productively meet. Astrophysics got a huge boost when the tools of radio and radar met the age-old science of astronomy. From this fruitful marriage came things like the discovery of the radiation from the big bang. Another example was...
In the example above, the authors claim that when ##r=r_0e^{\beta t}##, the radial acceleration of the particle is 0. I don't quite understand it because they did not assume ##\beta=\pm \omega##. Can anyone please explain it to me? Many thanks. ...
Human networks can demonstrate more rich dynamics and different mechanisms of self-organization compared to other types of networks. Considering an example of violin player ensemble, the authors show that by self-tuning tempo, amplitude, and coupling strength between players, their network achieves stab...
I am writing a lab report on the effect of the radius of a string on the frequency of rotation on an object in horizontal uniform circular motion. My hypothesis is: If the radius of the string from the origin of rotation increases, then the frequency will decrease because frequency has an...

I'm simulating on code the tight-binding sp3s* bandstructure of certain semiconductors, such as GaAs, AlP, InP, ZnSe, etc. with spin-orbit coupling at a temperature of T = 0 K but I'm having trouble at finding the corresponding spin-orbit splitting parameters. For example, I've found...
