FUZZY MODELOVÁNÍ: od logických paradoxů k Aplikacím

Logické paradoxy znepokojují filosofy a vědce již od starověku. Logika coby věda o korektnosti úsudků je totiž nepostradatelným nástrojem zejména v abstraktních disciplínách, kde správnost závěrů nemůžeme ověřovat experimentem, nýbrž se musíme spolehnout na logické odvozování: například v matematice, právu či filosofii, včetně metodologie vědy - tedy vlastně v samotných základech veškerého vědeckého poznání.

Mediation: A Degradation of Equality Before the Law?

In the wake of cuts to the Civil Courts, the coalition government have been arguing for mediation as an alternative to bringing cases before a judge. In 2011, a new protocol in the Family Courts compelled parties to family law cases to consider alternative means of settling their cases. In January 2012 Kenneth Clarke, the then Justice Secretary, said that mediation was the best way to solve divorce cases ‘cheaply and simply’. The focus on mediation has given rise to a lucrative area of business for lawyers, who can develop practices on the basis that they are robust mediators.

For many, the idea of resolving a case prior to a costly court case was very appealing. But are we at risk of creating a justice system in which finding an answer is prioritised over the exercise of legal judgement?

Setting up a tarp as a light block for light trespass

Light trespass is something we occasionally must deal with if we do not observe at a dark sky site. In this video, Dave explains how to set up a simple light-block using a heavy-duty tarp, a few stakes, some cord and two poles. This can enhance astronomy observing, and is a quick and eay set up / tear down too. See what’s up in the night sky every week with “Eyes on the Sky” videos, astronomy made easy.

Crash Course Literature 203 - Ghosts, Murder, and More Murder - Hamlet Part I

via thecrashcourse:

In which John Green teaches you about Hamlet, William Shakespeare’s longest and most-performed play. People love Hamlet. The play that is, not necessarily the character. Hamlet is a Tragedy with a capital T (I guess I don’t have to point that out, since you can see clearly in the text that the T was capitalized). By Tragedy, I mean virtually everyone dies at the end. John will talk a little bit about the history of the play and the different versions of it that have appeared in the centuries since it was written. You’ll also learn about some of the big themes in the play, get a brief plot overview, and the all important connections between Prince Hamlet and Simba, the Lion King. Seriously though, The Lion King is totally just a Hamlet musical with animals instead of people.

Why Do We Get Blackout Drunk?

If you’ve ever drunk too much, you might’ve experienced the phenomenon of “blacking out.” Why does this happen? Trace is here to explain what occurs in the brain once you’ve consumed a large amount of alcohol.

Water: A Polar Molecule

Paul Andersen explains how the polarity of water makes life on the planet possible. Oxygen is highly electronegative and pulls the electrons closely creating a partial negative charge. The polarity of water (and the corresponding hydrogen bonds) create cohesion, adhesion, capillary action, high specific heat, and a universally good solvent.

Journey to Chile’s Wild Islands

In February 2013, National Geographic Explorer-in-Residence Enric Sala led a team of scientists and filmmakers to the Desventuradas Islands off the coast of Chile. What they found there was an abundance of beautiful life and a place in need of protection.

Pristine Seas is a series of expeditions to find, survey, and preserve the last wild places in the ocean. For more information, visit http://www.pristineseas.org.

Polymer Springs Coil Like A Cucumber Plant with UV Light

Inspired by the cucumber plant, which has tendrils that coil to pull the plant toward the sun, chemists have developed liquid crystal polymer springs that move in response to light. Molecules that move like machines aren’t new. The advance here is that the same liquid-crystal film can produce many different kinds of motions— coiling, uncoiling, or helix inversion— depending on the direction a ribbon is cut from the source film. Also important is that the researchers were able to translate microscopic molecular motions to the macroscopic scale. The ribbons can ferry small objects, such as a 2 milligram magnet. They aren’t ready for practical applications yet, but Nathalie Katsonis of the University of Twente, who co-led the research team, thinks they may be applicable to microfluidic devices, or soft robotics.
