80. DEMO ERRORS

Errors in the demo associated with the lack of a logical connection between the arguments and the thesis.

The absence of a logical connection between the arguments and the thesis is called the fallacy of "imaginary following".

The imaginary following often arises because of the discrepancy between the logical status of the premises in which the arguments are presented, and the logical status of the proposition containing the thesis. Let us point out typical cases of violation of the demonstration, regardless of the types of inferences used.

1. Logical transition from a narrow area to a wider area. The arguments, for example, describe the properties of a certain type of phenomena, while the thesis unreasonably refers to the properties of the entire type of phenomena, although it is known that not all features of a species are generic.

2. The transition from what has been said with a condition to what has been said unconditionally.

3. The transition from what was said in a certain relation to what was said without regard to anything else. So, following will be imaginary if, relying on problematic, even very probable arguments, they try to substantiate a reliable thesis.

The error of imaginary following also takes place in those cases when, to substantiate the thesis, arguments are given that are logically unrelated to the thesis under discussion. Among the many such tricks, we name the following:

Argument for strength. Instead of a logical substantiation of the thesis, they resort to extra-logical coercion - physical, economic, administrative, moral-political and other types of influence.

Argument for ignorance. Using the ignorance or ignorance of the opponent or listeners and imposing on them opinions that do not find objective confirmation or contradict science.

Argument for profit. Instead of a logical justification for the thesis, they agitate for its adoption because it is so beneficial in a moral-political or economic sense.

Reason for common sense. It is often used as an appeal to ordinary consciousness instead of a real justification. Although it is known that the concept of common sense is very relative, it is often deceptive, if it is not about household items.

An argument for compassion. It manifests itself in those cases when, instead of a real assessment of a particular act, they appeal to pity, philanthropy, compassion. This argument is usually resorted to in cases where it is a question of the possible conviction or punishment of a person for committed misconduct.

Argument for loyalty. Instead of substantiating the thesis as true, they tend to accept it by virtue of loyalty, affection, reverence, etc.

Argument for authority. Reference to an authoritative person or collective authority instead of a specific justification for the thesis.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

Toshiba Exceria Pro CompactFlash Memory Cards 01.05.2013

Toshiba calls the fastest Exceria Pro memory cards in CompactFlash format. The new media is designed for high-end digital SLR cameras. The cards use Toshiba's NAND flash memory.

The series includes models with a capacity of 16, 32 and 64 GB. All of them support UDMA 7 mode, comply with the CompactFlash 6.1 specification and comply with the requirements of the Video Performance Guarantee Profile 2 (VPG-65) standard. This means that the write speed is guaranteed not to drop below 65 MB / s (of course, subject to the use of appropriate hardware). In fact, according to the manufacturer, in read mode, the cards reach speeds of up to 160 MB / s.

In recording mode, the 32 and 64 GB models show speeds up to 150 MB / s, the younger model - up to 95 MB / s.
