Data analysis.

Data analysis is the bridge from observation to conclusion. It is the process of making sense of reality as one becomes aware of it. In life a subject always perceive signals via his detectors like eyes, ears, skin, nose and tongue. A brain of human being continuously analyzes enormous flow of data in routine subconscious manner when only very small portion is on the level that can be verbally described and formally mathematically processed at the modern level of science.
The area of science called artificial intellect, AI, is doing enormous progress in modeling behavior of alive being that is manifesting itself in technological achievements like in self-driving cars, automatic voice callers, personalized web-advertisement, automatic diagnose system such as IBM Watson and robots of all kind. The advanced data analysis is integral part of AI.
Data analysis uses to solve life problems these could be formulated in terms of mathematics. The same is more and more applicable now to the science in general that has experienced evolution from collection and classification of anecdote like observations to mathematically formulated fundamental laws of nature.
Without pretending to cover all areas of data analysis even on its most basic there will be articles describing some problems in life that can be solved by methods of data analysis and shown how to do it with the held of LeoDataAnalysis.

Crystal growth.

A crystallization phenomena manifests itself in a long list of natural and technological processes. Crystals are solid materials with atoms located in regular position defined by long distance symmetry. The structure of crystals gives each of them special and often unique properties essential for material culture of civilization. The rate of transformation of atomic structure motive of matter from liquid or gas state into crystals plays important role in series of industrial productions of variety construction and other industrial materials as well for research of earth minerals formation in geology and in space bodies in cosmology.

There is expanding industry for production of bulk single crystals for subsequent usage in electronics or for gems in jewelry. An optimization of the technology presumes increasing productivity that is equivalent in this case to finding a maximum rate of crystal growth securing in the same time a quality of the crystal that means keeping concentration of defects on atomic and higher scales on acceptable level. In ranking by influence on the product output the kinetics of crystal growth stays comparable very close here to the thermo- and mass- transportation phenomena.

The knowledge of how much lower temperature on the border of the crystal could be set during its growth without deviating from layer-by-layer mechanism of growth that provides the best possible quality of the crystal. For mass produced construction materials like metals and alloys, fine ceramic, Portland and high-alumina cements and for many other materials in industry the crystalline content of the product is strongly depend on time-temperature conditions of treatment of the raw mixture materials. Taking into account that different crystalline phases can have mismatched rates of their spreading out (crystal growth rates could be and mostly are different for them at the same temperature), the knowledge how atomic structure of crystals influences kinetic of crystallization could help in choosing strategy for experiment planning in development of the best quality products. There is necessity to avoid crystals formation during  production of materials with amorphous atomic structures like commonly used glasses or more exotic materials like fast frozen amorphous metals.

The knowledge of growth rate of crystals in initial melts as a function of temperature can provide guideline to defining minimum cooling rate that is nevertheless fast enough to avoid formation of the crystals in glass forming melts. Formation of thin films on monocrystal substrates in vacuum by physical or vapor deposition demands knowing the rate of crystal growth at given temperature. To obtain crystalline film the velocity of material deposition should be at least slower compare to the crystal growth rate. A petrography analysis of samples in geology or found in meteorite rocks permits to obtain their crystalline content. Additional information about relative growth rate of these different crystalline phases helps to deceiver a history of physical conditions of their places of origin.

Christmas 2018 vacation in Sunny Isles, Florida.
It was the best choice to have vacation 2018 just week before Christmas day in Miami area in Sunny Isles. The time before Christmas in Miami has happened to be slow and not as cheerful as our previous visits. Night life at South Beach did almost not exist. Compare to my first visit at 2001 South beach is if not dead but close to mortal illness. Most of windows at new high-scraper apartment buildings are dark and practically no activity at fronts at day time. But ocean is still warm, sun is bright and beaches are sandy. Mixed feeling prevail in my mind all at all.
St. Thomas, USA Virgin Islands
Our visit in St. Thomas, USA Virgin Islands at Breakaway trip from New York to Caribbean islands was at January 19, 2017. St. Tomas is island with small town Charlotte Amalie and big Magen`s Bay Park beach. The Magen is arguable at the very top of the list of best Caribbean and probable world beaches. The long, with regular transportation, with natural shades from palm trees, fine sand, warm water, pelicans and iguanas.
Tortola, British Virgin Islands
We were in Tortola, British Virgin Islands at January 20, 2017 during Breakaway trip from New York to Caribbean islands. Tortola is mostly wild nature mountain terrain with small density estates here and there. The main attraction was a beach at Brewers Bay that is nice place with almonds nuts lying under trees near by to the shore. Natives come at morning to gather these nuts. We tasted these almonds Ė nothing extraordinary to report except circumstances.
Castries, St_Lucia
We were in Castries, St_Lucia at January 24, 2017 during Breakaway trip from New York to Caribbean islands. The island of Saint Lucia made impression divided between very rich and poor much sharper than other Caribbean we were. Impressive big estates located at shore are not neighboring to not attractive places for existence on the sides of inner roads. Not my first choice for anything. Beach whether was perfect nevertheless.
Basseterre, St. Kitts
We were in Basseterre, St. Kitts at January 25, 2017 during Breakaway trip from New York to Caribbean islands. The island of Saint Kitts is sort of nice and it is most precise description of its individuality. The town of Basseterre has Central Square with fancy clock tower. At the morning the big cloud was covered Mount Liamuiga as if white hat pulled down to the neck.
Bridgetown, Barbados.
We were in Bridgetown, Barbados at January 23, 2017 during Breakaway trip from New York to Caribbean islands. The island of Barbados was most south point of that trip and that was noticeable at winter time. Bridgetown near port area looks like normal small urban city. The main attraction is Chamberlain Bridge across Constitution River with Independence Arch at one side. Near the town in minutes walk is Carlisle Bay beach that provides everything for scuba diving ships wrecks observation and sea turtle close encounters.
Roseau, Dominica.
We were in Roseau, Dominica at January 21, 2017 as one of the destinations during Breakaway trip from New York to Caribbean islands. The island of Dominica is distinct itself from others in Caribbean to be volcano formed. There are no sand beaches in convenient distance from the town of Roseau but presence of botanic garden with exotic flowers compensates enough tourist needs to visit one time.
Saint Maarten vacations in 2018.
We were at St. Maarten in January of 2018. It was out third visit to the island. Previous two was with cruise trips. This time it was just after hurricane and for two weeks. We rented studio at Mont Vernon near Orient Beach and explore what Saint Maarten can offer.
Spectacular nature phenomenon of rainbow without setting any special experimental instrumentation reveals to observer the fact that light consists of spectrum of pure colors (actually it is not entirely correct statement). At very least the lesson of rainbow is that white light of sun is in fact mixture of colors. Here is a collection of my photos of rainbow and one also of halo close related effect taken in different times and places.
Creation and transition into virtual reality world is the only true road to everlasting life.
The only true way for eternal life is transition of the human conscious from material body into the world of virtual reality. Although modern technology is still far away for achieving this goal the test for defining a equality of virtual person with its physical prototype can be defined already setting roadmap of key technological breakthroughs for transition into virtual worlds.
