Unlike religious beliefs, the criticism of political beliefs shouldn't be suppressed in general. This is because the qualities of political beliefs can clearly be judged through some trials. In democratic societies, people can choose what they like either directly or indirectly while reflecting the outcomes of some political trials. Any discussions about the political systems and measures should be encouraged in most cases. Desirably, the criticisms should be made positively and constructively in the discussions.

Because of its extreme idealism, some people have a tendency to take communism as a religious belief. Obviously, it isn't right. It's a political belief. Communism and its preliminary were unsuccessful in some trials in modern history owing to some obvious failings. At the present time, communism is of some value to the people who would like to criticize the essence of utopian socialism, corruption of government officials in socialist countries, and exaggerated appreciation of capitalists in capitalist countries, and to provide for people's retreat.
As written several times in my diary, it's my belief that capitalism with proper social security is nearly optimum for many countries for now and in the near future. Communism might work if a unified nation should be established in the far future.

There are considerable differences in the senses of values of tears between the sexes, ages, races, cultures, regions, and teachings. People's sense of values of tears have also changed with the times. The values of tears aren't absolute. There are various opinions on shedding tears. For some people, an emotional expression with shedding tears may give a good impression. Tears may be useful to reduce stress and to exercise self-control. For others, a mental state when shedding tears is an indication of unstableness and weakness. One's attitude of never shedding tears may make him or her look tough. As long as tears are put to good use in a constructive manner, I think that it's okay.
Under an adverse or serious situation, people don't just have it in them to weep. It seems to me that, as people are better off, they are more easily moved to tears for a given condition in general.

The standard model consisting of the two theories, the electroweak and the quantum chromodynamics theories, is a framework of theories that describes three out of the four fundamental interactions, that is, the electromagnetic, weak, and strong interactions most accurately and comprehensively in the experimentally proven theories. However, because as a matter of course the standard model was developed based on various approximations, it doesn't describe physics exactly. It's the best proven theory but isn't perfect. The attempts to unify the strong and electroweak interactions into a simpler gauge group have been made by reducing the number of three independent coupling constants of the SU(3) x SU(2) x U(1) gauge group down to two or desirably one at the high energy of about 10 to the fifteenth GeV and above, but the agreements of their predictions at a lower energy calculated using the renormalization group method to the experiments have been unsatisfactory. Although the introduction of supersymmetry to the grand unified theory may improve the agreement, there is no definite experimental evidence to support its validity. No proven field theory describing the gravitational interaction has been successfully unified so far, mostly because of the difficulty in both the experimental verification and the renormalizable calculation of a proposed theory. It's going to be quite some time before the particle accelerator that is capable of reaching the energy level above which the gravitational interactions become strong becomes available. In a lower energy level, it's very difficult to carry out accurate observations on the gravitational interaction between elementary particles because it's much weaker than the other three interactions and can't easily be separated out from its very wide-range interactions with numerous other massive matters around. There are some other difficulties in studying the hypothetical theories such as the superstrings theories that might enable the quantum field theory to describe the gravitational interaction as well as the other three interactions, in terms of evaluating the validity of treating elementary particles as the vibrating infinitesimal strings instead of the dimensionless points in order to evade the unwieldy divergences and of narrowing the possible versions of the proposed superstring theories down by experiment. In the framework of the standard model, elementary particles are approximated to be dimensionless points carrying various properties. Most possibly, any elementary particle isn't exactly so. Most scientists think that this approximation is reasonable but troublesome. At the present time, nobody knows what an elementary particle is, a dimensionless point, a very small sphere, a very small string, or something else.

Most branches of physics made very exciting progress from the dawn of quantum mechanics. However, the advancements of some branches of physics e.g. particle physics, high-energy physics, etc. based on quantum field theory have grown rather stagnant because of the above-mentioned reasons since the latter period of the twentieth century. Some physicists may have proposed a mechanism, other than the Higgs mechanism, that endows masses on leptons and quarks through something related more directly to the mechanism of the gravitational interaction. However, it's going to be quite some time probably before the experimental evaluation of such mechanism becomes possible. Therefore, the Higgs mechanism, which is a part of the standard model, should be a standard theory in science today.
Although the advancements of the quantum field theories have grown stagnant, those of cosmology and astrophysics, which require a comprehension of the quantum field theories, have been growing active in accordance with those of space developments. It might become possible to conduct some precise experiments when an experimental apparatus is built somewhere in interstellar space far in the future, though there is another sort of hindrance to an experiment due to high-energy galactic cosmic rays.

There are various applications of the quantum field theories to other branches of physics, other academic areas, and technologies. As written yesterday, in order to understand cosmology and astrophysics in detail, a certain amount of knowledge of the quantum field theories is essential. The comprehensions of some singular phenomena of solid-state physics require the perspectives from the quantum field theories indispensably.

Superconductivity is the remarkable physical phenomenon in the solid-state material where electromagnetic gauge invariance is spontaneously broken. In the system of a superconductor, the gauge symmetry group is assumed to be broken by the vacuum expectation value of the fields of the Cooper pair, which is the electron pair formed through the attractive interactions between two approaching electrons with spins opposite in direction because of the exclusion principle and momenta equal in magnitude and opposite in direction because of translation invariance via the so-called lattice deformation, which can be said, in other words, via the interactions with the phonon, below its very low critical temperature. The phonon, which is a quantum of vibration energy of a crystal lattice, is indeed a Goldstone boson in a superconducting material. The properties of a superconducting material can be calculated quantitatively by means of the renormalization group methods from an effective Lagrangian consisting of the Cooper pair fields, which are equivalent to the products of the two-electron fields at a stationary state while taking the peculiar influences of these effective interactions among electrons into account.
One of the interesting properties of the superconducting material is zero electrical resistance on account of the time-independence of the Goldstone and charged fields in the steady current, and one of the applications utilizing this property is a superconducting magnet, as well known. Another property is a set of the Josephson effects, and one of the applications utilizing this property is the Josephson device, which consists of two pieces of superconducting metal wire separated by a thin tunneling insulator and can be the unit device, the quantum state of which is dealt with as the qubit state capable of superpositioning in a potentially-high-speed quantum computer only operational at a very low temperature.

My first impression from the image of Mars having a haze localized near a region on its surface for a short period of time that recently appeared on the page of the web news was that it's probably caused by the impact of a meteorite rather small in size. Because Mars' atmosphere is very thin, I guessed that the meteorite strikes on Mars' surface are much more frequent than those on Earth's surface. I don't think that somebody made a dangerous experiment over there. The web news wrote that it's attributable to other causes.

The Outer Space Treaty includes the principles prohibiting the use of outer space including the moon and other celestial bodies for military purposes. The agreements between not a few countries have been ratified up to the present. In our time this treaty is quite reasonable. However, some major modifications to this treaty would be necessary if the abolition of a weapon of mass destruction were to be complete on the earth sooner or later, and if the unified nation were to be established in the far future.

I remember that the method to calculate the electronic properties of a superconductor near absolute zero point from the effective Lagrangian consisting of the electron pair fields about which I recently read in a section of the three volumes of a physics book as thick as a telephone directory is basically same as what I leaned briefly in a lecture room more than two decades ago, though a lecture didn't include any detailed explanations for the application of the spontaneous symmetry breakdown to the study of superconductivity and the validity of the use of this sort of the effective Lagrangian for the purpose of it probably because of constraints of lecture time. In the type-II superconductors, which are very useful being capable of maintaining the superconducting state firmly under a high external magnetic field, the calculation of their properties should be more complicated because the stable vortexes characteristic of this type of superconductors are formed inside certain intermediate conditions in general, but the vortexes can be rather easily modeled.
Scientists' attentions and efforts have been turning to the discovery of a new material that exhibits its superconducting state at as high a temperature as possible and the elucidation of its mechanism as precisely and comprehensively as possible for the last few decades. In order to obtain a higher degree of expertise in the theories describing the properties of the superconductors with higher critical temperatures, which probably require some other insights into solid-state physics, I may need to examine some books specialized for this subject or some technical papers.

For the last two months since the beginning of this year, NHK has broadcasted all five series of TV programs designed to provide viewers with images of the possible future world. As many SF movies do, these TV programs also leaned toward rather overestimation of the changes in the lifestyles and the environments in which people of the future world about thirty years from now live, driven mostly by the advancements in various kinds of technologies. Probably, some degree of excessive overestimation of the coming changes was incorporated into these programs on purpose in the views of providing entertainment for viewers and raising their hopes for future. The contents of series three of this program are rather agreeable to my opinions.
In many cities of the currently developing countries, sweeping changes should occur at a hectic pace for the next few decades and further. To put it briefly, it can be said that what will happen there is the modernization. In other words, it's catching up with developing countries. However, the changes in the lifestyles and the environments of people in the currently developed countries for the same period of time won't be so aggressive. The comparison between the prospective changes in the lifestyles and the environments of people of today into people of the future world thirty years later shown on TV and the actual changes in those from people of the past world thirty years earlier into people of today can give a grasp of the appropriateness of what I wrote above.

The most remarkable change in the lifestyle and the environment in which people of the future world about thirty years from now is something related to the increasing changes in the earth's climate and the heightening regulation on the uses of dwindling renewable fossil fuels. This should be one of the major tractive efforts to propel the electrification of consumer electrical appliances and automobiles. Although the electrification should progress certainly, it seems to me that at a glance there won't be any dramatic change in the appearance of future consumer electrical appliances in the houses and automobiles on the roads.
The significant advancements in medical treatments by virtue of the developments and the widespread of the coming regenerative medicines, correspondingly to those of the antibiotics, anesthesia, vaccines, and other medicines that have been appearing since the middle of the twentieth century, may potentially prolong peoples' lifespan by leaps and bounds and may also help people look younger in this period of time. Although for instance, some future treatments may allow an eighty-year-old person to look like sixty years old, there won't be any dramatic change on the whole in the scenes of future people's life in public and private within this time span.
The developments and the widespread of personal devices that are capable of accessing the Internet by wired or wireless, such as personal computers, cell phones, and other mobile gadgets, are the most significant changes identified in the lifestyles and the environments of people of today are compared to those of people of the past world thirty years earlier. What would be most probably the next game changer may be found in the category of robotization and even more computerization of the existing tools and the inventions of the epochal human interfaces with these tools. Needless to say, however, it doesn't mean a humanoid. It may be a technology that's spun off from a large contractor for the government and popularized by a venture firm, or it may be a technology that a private company could start up from scratch.

Artificial Intelligence is a type of newer computer system that's capable of carrying out the tasks that require human intelligence up to date. The development of AI has been progressing and the applications of it to the industrializations and the logistics are coming. AI may be useful for police forces and intelligence organizations to find either a suspect or a potential criminal by gathering some clues selectively from the deluge of information through the Internet and so on. Human-like information gathering extended over the world without ceasing can also be potentially beneficial for the purpose of marketing in business circles. The advancement of AI should also be expected to improve the capability of desirable language translators rapidly.
The UCCR theory suggests that future events aren't predetermined exactly, and what ordinary people can do is to estimate the probabilities of these events ahead of time by relying on their intuitions or technologies. The computer is currently the most powerful tool to help us estimate the probability of a simpler future event within expectation when the phenomena associated with it are well understood and modeled. However, even with the efficient use of a supercomputer, it's difficult for everybody to forecast complicated matters that depend upon various kinds of factors and may be very sensitive to some unknown minor factors. Weather forecast is a familiar example of the matter of complexity dealing with a few kinds of continuously varying fluid that wrap around the intricate planet Earth. It seems to me that the development of AI in its infancy isn't so beneficial to improving the accuracy of forecasting complicated matters. Because the difficulty in forecasting these complicated phenomena is attributable mostly to the insufficiency of elucidating the laws hidden in the complexity, AI in its infancy can't wonderfully help improve the accuracy of the forecasts. Early AI may help improve the accuracy of forecasting a rather simple future event within expectation by gathering selectively in the similar way that humans usually do a large mass of necessary information from the cloud of information through the Internet and others without rest. Considering the chaos theory, AI won't be able to forecast various kinds of future events in social life accurately within the next thirty years because there should always remain no small number of minor factors that both humans and AI won't know. Considering the UCCR theory, it will never be able to do so because it's impossible theoretically.
I believe that AI in its maturity should be a promising candidate for a judge in the administration of justice in the far future world. It's obvious that the greatest advantage of introducing an AI judge is its fairness close to potential perfection. Although there are always some rooms in every system for the swindlers to play tricks for their convenience, the introduction of an AI judge, the system of which is strictly checked with an unbiased eye at regular intervals, and the access of which is completely isolated from the network, may help minimize the number of rooms. However, without improving the efficiency of the systems of the legislature in order to respond immediately to the necessities of the day while maintaining justice and fairness, the project of an AI judge will hit some roadblocks soon. Essentially an AI judge always needs the opportune inputs of reasonable laws, suits, and testimonies. It's certain that an AI judge won't become a reality within the next thirty years.

As many SF novels and movies have ever told, it's probably true that AI could be dangerous for human beings when its ability exceeds a certain level. In terms of speed in calculation, the capacity of memorization, and the game requiring simple decision-making, a computer had already been intellectually superior to a human. At the present stage, however, a computer isn't good at performing other tasks, such as inferences, recognitions, decision-making of complex matters, learning, spontaneity, emotions, imagination, and so on. It can be said that the effort to develop AI is the attempt to give the abilities that are currently right up human's street to a computer. I am not sure whether AI will be able to surpass human intelligence in the near future or not. The truth of the dangerousness of AI is conditional on this point.
People can carefully manage both the development and the introduction of AI within the context of possible risks and expected benefits yielded by the uses of growing AI. As long as some intellectual abilities such as spontaneity, emotions, and imagination aren't given to it, AI can't become a menace to human beings. It seems that early AI doesn't possess these highly intellectual abilities because of some development difficulties. The imposition of some restrictions on the development of these abilities for AI may be necessary sooner or later. To give an example of risk management of the introduction of AI uses to the government business, the commission of future AI in its maturity could be restricted only to the administrations of justice as a leading part. More careful people may want to limit AI uses only to a supporting role in the judicature. It isn't difficult to see that if future AI beyond human intelligence were to be given full authority to control not only the judicature but also the legislature and the executive far in the future, dark clouds might cast a pall on the future human world. Anyway, in the government of a country, AI will be firstly used to assist in information gathering for the police forces and the intelligence organizations, which are the important parts of the executive. They may have already been using it in some countries.
