According to this symmetric scale distribution law of different scale regions: (a) we naturally give a possibility overcoming the difficulty of the desert effect between the grand unification scale and electroweak unification scale relevant to quarks and leptons, and it is really surprising to discover that the scales of quarks & electrons, protons & neutrons and atoms again all sequentially locate at the predicted points of the scale space;(b) we closely uncover the scale of the cells, which is the basic unit constructing the human bodies;(c) even the average height of human being is naturally deduced;(d) further, it is very surprising that the scales of the celestial bodies tightly related to us human beings, including the earth and the sun, also exactly fall at the predicted points in scale space in order. Therefore, all these scales with 105n cm order (n = 0, 1, 2, …, 9) above just give a proof of very key anthropic principle for whole mankind (which just makes the anthropic principle be reduced as anthropic theorem), i.e., matter stratums (a) and (b) are inorganic and organic bases of constructing human being respectively;matter stratum (c) is just human being;matter stratums (d) are the living environments of human being. Namely, everything is for or relevant to the existence of human being. Consequently, the experimentally checked scale ladder of well-known matter levels just coincides with the scale ladder predicted by the deduced distribution law. From Planck scale to the Sun scale, people may systematically build up the exact scientific theories corresponding ten matter stratums, may set up the different sciences among the different cross stratums, further, 展开更多

The queuing model based on task priorities is to some extent successful in explaining the origin of such heavy tails, however, it cannot explain all the temporal statistics of human behavior especially for the daily entertainments. We propose an interest-driven model, which can reproduce the power-law distribution of interevent time. The exponent can be analytically obtained and is in good accordance with the simulations. This model well explains the observed relationship between activities and power-law exponents, as reported recently for web-based behavior and the instant message communications.展开更多

This climatic phenomenon (formation of negative charge in that case) has long been considered as physical phenomena of very small space-time scales. Now we have good reasons to say that this perception of troposphere electrical status is totally meaningless. Indeed, it is now easy to show that significant numbers of electrons are provided to troposphere at each appearance of a thunderstorm (or a lightning flash). Thereafter, movement implemented in the troposphere by winds (e.g., West African aerojet) contributes to the formation of low altitudes Electrojets (e.g., West African Equatorial Aerojet gives birth to West African Equatorial Electrojet). The existence of Low Layers Equatorial Electrojets (LL-EEJ) was totally unknown by the first theorists who have studied the Earth’s Ionosphere Plasma Physics and Electrodynamics. This mistake has led their followers to many questions unanswered in their attempt to explain the longitudinal and seasonal variations of observed EEJ. In this paper, we will provide many useful explanations on the manner in which clouds provide oxygen to troposphere and thereafter trigger negative static charges (e-) throughout both troposphere and ionosphere. Indeed, this paper also explains how, opportunely, the ITF (inter tropical front) plays the role of the tap which facilitates oxygen transfer from troposphere to ionosphere. Detailed studies on the Earth’s troposphere plasma physics and electrodynamics are impatiently awaited.展开更多
