technology. EEG measures fluctuations in the electrical activity directly below the scalp, which occurs as a result of neural activity. By attaching electrodes to subjects' heads and evaluating the electrical patterns of their brain waves, researchers can track the intensity of visceral responses such as anger, lust, disgust, and excitement. The fMRI, on the other hand, uses a giant magnet to tra

subject of ElGamal cryptosystem especially, actually the fact that its security is based on the difficulty of finding discrete logarithms modulo a large prime in a finite field is quite interesting.
And also the fact that math is used for splicing telephone cables attracts us and we are curious about how the number theory can help to make the splicing telephone cables. Telephone lines are cons
