Abstract**

A new methodology allowing one to execute numerical computations with finite, infinite, and infinitesimal numbers on a new type of a computer – the Infinity Computer – is introduced. A calculator using the Infinity Computer technology is presented during the talk. The new approach is based on the principle ‘The part is less than the whole’ introduced by Ancient Greeks that is applied to all numbers (finite, infinite, and infinitesimal) and to all sets and processes (finite and infinite). It is shown that it becomes possible to write down finite, infinite, and infinitesimal numbers by a finite number of symbols as particular cases of a unique framework (different from that of the non-standard Analysis). The new methodology evolves ideas of Cantor and Levi-Civita in a more
applied way and (among other things) introduces infinite integers that possess both cardinal and ordinal properties as usual finite numbers.
Note that foundations of the Set Theory dealing with infinity have been developed starting from the end of the XIX-th century until more or less the first
decades of the XX-th century. Foundations of the classical Analysis dealing both with infinity and infinitesimal quantities have been developed even earlier, more than 200 years ago, with the goal to develop mathematical tools allowing one to solve problems arising in the real world in that remote time. As a result, these parts of Mathematics reflect ideas that people had about Physics (including definitions of the notions continuous and discrete) more than 200 years ago. Thus, these mathematical tools do not include numerous achievements of Physics of the XX-th century. Even the brilliant non-standard Analysis of Robinson made in the middle of the XX-th century has been also directed to a reformulation of the classical Analysis (i.e., Analysis created two hundred years before Robinson) in terms of infinitesimals and not to the creation of a new kind of Analysis that would incorporate new achievements of Physics.
The point of view on infinite and infinitesimal quantities presented in this talk uses strongly two methodological ideas borrowed from the modern Physics:
relativity and interrelations holding between the object of an observation and the tool used for this observation. The latter is directly related to connections
between different numeral systems used to describe mathematical objects and the objects themselves.
The new computational methodology gives the possibility both to execute numerical (not symbolic) computations of a new type and simplifies fields of
Mathematics where the usage of the infinity and/or infinitesimals is necessary (e.g., divergent series, limits, derivatives, integrals, measure theory, probability theory, fractals, etc.). In particular, a number of results related to the First Hilbert Problem and Turing machines are established and a new concept of continuity better reflecting the modern view of physicists on the world around us is introduced. Numerous examples and applications are given: approximation, automatic differentiation, cellular automata, differential equations, linear and non-linear optimization, fractals, percolation,
processes of growth in biological systems, etc.

Abstract**

Data in applications are frequently not precise numbers, vectors, and symbols but more or less non-precise also called fuzzy. All measurement results of continuous quantities are subject to fuzziness. This makes it necessary to describe data by fuzzy models before analyzing them. There are different kinds of uncertainty related to data analysis and especially statistics. The most important are variability, imprecision of data, model uncertainty, and uncertainty of a-priori information. Whereas variability is modeled since a long time by probability models, the quantitative mathematical description of imprecision by so-called fuzzy models was done more recently. Especially in statistical data analysis in a Bayesian context also a-priori information is best modeled by so-called fuzzy probability distributions. Examples of non-precise data and related fuzzy models as well as adapted statistical data analysis will be given in the contribution.

Abstract**

Robotics researchers increasingly agree that ideas from biology and self organization can strongly benefit the design of autonomous robots. While in classical robotics there is a clear distinction between the control and the to-be-controlled, in biological systems part of the functionality is incorporated into the morphological and material characteristics: the task of coping with impact in human walking, for example, is taken over by the elasticity of the muscle-tendon system. In other words, part of the "computation" is taken over by the morphology of the agent, thus the term "morphological computation". On the sensory side, the spatial arrangement of the sensors on the body provides information about the stimulus. Biological systems which are - with the exception of the skeleton providing structural support - largely soft and elastic (to varying degrees), capitalize on "morphological computation" by exploiting their morphological and material characteristics as well as processes of self-organization. These ideas play an essential role in the design of next-generation intelligent agents as in the recent field of "soft robotics". Although many challenges remain, concepts from biology and morphological computation will eventually enable researchers to engineer machines for the real world that possess at least some of the desirable properties of biological organisms, such as adaptivity, robustness, and versatility.
