The others are experimental, meaning that there is a difficulty in creating an experiment to test a proposed theory or investigate a phenomenon in greater detail. SOME FAMOUS UNSOLVED PROBLEMS Goldbach conjecture: Every even number greater than four is the sum of two primes. Based on these findings, the basic principles of a rotating field plasma separator are then introduced. 1 Notations, de nitions and basic properties should be consulted by the fol-lowing monographs: The explanation behind the fourth problem is an extension of the third problem. In light of these results, challenges associated with this original separation process are underlined, and the main directions for a future research program aimed at this important unsolved problem of applied plasma physics are identified. UNSOLVED PROBLEMS IN PHYSICS AND ASTROPHYSICS CONTENTS Abstract 1.

Overview: This is a web site for amateurs interested in unsolved problems in number theory, logic, and cryptography. Problems are solved under Lorentztransformationsoflength,time,velocity,momentumandenergy,theinvari-ance of four-momentum vector, transformation of angles and Doppler effect and threshold of particle production. UNSOLVED PROBLEMS Edited by O. Strauch Editorial Board welcome papers containing some progress in problems listed below. Introduction 2. Chapter 6 deals with the special theory of Relativity. During the long-term process of evolving theories according to the scientific method, there is an intermediary phase between two periods of stability where questions remain unanswered and more and more anomalies accumulate to cast doubt on the established theories in search of greater consistency with experiments. Goldbach, 1742, in letter to Euler Schnirelman, 1939: every even number can be written as a sum of not more than 300,000 primes Known to be true for numbers 4 1018 21 collected papers}, author={F. Smarandache and Zhao Feng-juan and Fu Yu-hua}, year={2014} } Einstein’s general theory of relativity cannot explain the perihelion motion of Mercury. Please read the FAQ. Unsolved Problems Of Noise And Fluctuations. Some of the major unsolved problems in physics are theoretical, meaning that existing theories seem incapable of explaining a certain observed phenomenon or experimental result. In Number Theory, Logic, and Cryptography. Also it welcomes open problems in the line of the aim of this UDT for possible publication in this section. Chapters 7 and 8 are concerned with problems in low energy Nuclear physics. Home .
