'''Joseph Stefan''' ({{lang-sl|Jožef Stefan}}) (24 March 1835 – 7 January 1893) was a [[Carinthian Slovene]] [[physicist]], [[mathematician]], and [[poet]] of [[Austrian Empire|Austrian]] citizenship.
 
== Life and work ==
 
Stefan was born in an outskirt village [[St Peter, Austria|St Peter]] (Slovene ''Sveti Peter'') near [[Ebenthal]] (Slovene ''Žrelec'') (today a district of [[Klagenfurt]]) (''Celovec'') in the [[Austrian Empire]] (now in [[Austria]]) to father Aleš (Aleksander) Stefan, born in 1805 and mother Marija Startinik, born 1815. His parents, both ethnic Slovenes, were married when Jožef was eleven. The Stefans were a modest family. His father was a milling assistant and mother served as a maidservant. Stefan's father died in 1872 while his mother died almost ten years earlier in 1863.
 
Stefan attended elementary school in Klagenfurt, where he showed his talent. They recommended that he continue his schooling, so in 1845 he went to Klagenfurt gymnasium. He experienced the revolutionary year of 1848, as a thirteen-year-old boy, which inspired him to be sympathetic toward [[Slovene literature|Slovene literary]] production.
 
After having graduated top of his class in high school he briefly considered joining the [[Benedictine]] order but his great interest in physics prevailed.  He left for Vienna in 1853 to study [[mathematics]] and [[physics]]. His professor of physics in gymnasium was Karel Robida who wrote the first Slovene physics textbook. Stefan then graduated in mathematics and physics at the [[University of Vienna]] in 1857. During his student years, he also wrote and published a number of poems in Slovene. He taught physics at the University of Vienna, was Director of the Physical Institute from 1866, Vice-President of the Vienna Academy of Sciences and member of several scientific institutions in [[Europe]].  
 
He published nearly 80 scientific articles, mostly in the Bulletins of the Vienna Academy of Sciences, and he is best known for originating a [[physical law|physical]] [[power law]] in 1879 stating that the total [[radiation]] ''j''<sup>*</sup> from a [[black body]]  is proportional to the fourth power of its [[thermodynamic temperature]] ''T'':
 
:<math> j^{\star} = \sigma T^{4}</math>
 
This law was mathematically derived from the measurements of French physicists Dulong and Petit. As both incident radiation and blackbody emission are always equal, this equation applies equally to the temperature of any ideal body subject to incident radiation across its surface. In 1884 the law was extended to apply to grey-body emissions by Stefan's student [[Ludwig Boltzmann]] and hence is known as the [[Stefan–Boltzmann law]]. Boltzmann treated a [[heat engine]] with [[light]] as a working matter. This law is the only physical law of nature named after a Slovene physicist. Today we derive the law from [[Planck's law of black body radiation]]:
 
:<math> j^{\star} = \int_{0}^{\infty} \left( {dj^{\star}\over d\lambda} \right) d\lambda </math>
 
With his law Stefan determined the temperature of the [[Sun]]'s surface and he calculated a value of 5430 [[Celsius|°C]]. This was the first sensible value for the temperature of the Sun.
 
Stefan provided the first measurements of the [[thermal conductivity]] of [[gas]]es, treated [[evaporation]], and among others studied [[diffusion]], [[heat conduction]] in [[fluid]]s. For his treatise on [[optics]] he received the Richard Lieben award from the University of Vienna. Flow from a droplet or particle that is induced by evaporation or sublimation at the surface is now called [[Stefan flow]] because of his early work in calculating evaporation and diffusion rates.
 
Very important are also his [[Stefan electromagnetic equation|electromagnetic equations]], defined in [[vector (geometry)|vector]] notation, and works in the [[kinetic theory]] of [[heat]]. He was among the first physicists in Europe who fully understood [[James Clerk Maxwell|Maxwell's]] [[electromagnetism|electromagnetic theory]] and one of the few outside of England who expanded on it. He calculated [[inductance|inductivity]] of a [[coil]] with a quadratic cross-section, and he corrected Maxwell's miscalculation. He also researched a phenomenon called the [[skin effect]], where high-frequency [[electric current]] is greater on the surface of a [[Conductor (material)|conductor]] than in its interior.
 
In mathematics the [[Stefan problem]]s or Stefan's tasks with movable boundary are well known. The problem was first studied by [[Gabriel Lamé|Lamé]] and [[Benoît Paul Émile Clapeyron|Clapeyron]] in 1831. Stefan solved the problem when he was calculating how quickly a layer of [[ice]] on water grows ([[Stefan's equation]]).
 
He died in [[Vienna]], Austria-Hungary.
 
His life and work is extensively studied by the physicist [[Janez Strnad]].
 
== Eponymous terms ==
 
In physics, several concepts are named after Joseph Stefan. In particular:
* [[Stefan–Boltzmann law]]
* [[Stefan–Boltzmann constant]] σ
* [[Stefan problem]]
* [[Stefan's equation]]
* [[Stefan's formula]]
* [[Stefan flow]]
* [[Stefan number]]
* [[Stefan force|Stefan's force]]
 
The [[Jožef Stefan Institute]] was also named after him.

This article will now explain stretching exercises that will strengthen and thicken your cartilage, which results in an increase of your stature by at least 2-3 inches. I ran into a school friend the other day and couldn't help notice how old he had gotten, I said hello and he didn't even recognize me. Giraffes can go several days without drinking because the leaves they eat contain a lot of water. This is because while you are sleeping, your body produces growth hormones. Maximize your height potential with a secret for calorie consumption, together with how to exploit a wonder vitamin.

This will cause the ligaments, tendons and the muscles to really stretch and you will gain longer legs. However, when coupled with the high temperatures you can quickly end up with dried out hard pan if the lawn bed is exposed to direct sunlight. Having the right rims has nothing to do with your exhaust system, but they will make your car will look good. It is nice to find programs online that actually answer the all time question of, “How can I get taller. ' 'How much height do I realistically expect to gain from using a growing pill.

Nowadays I have found the funny side and I can even laugh at myself for being that clumsy bloke, this is fine now but through my younger years it was not so easy. While this is completely normal, you may encounter soreness and some muscle fatigue along the way. Having the right wheels on the right car can say a lot about one’s passion or love for cars and the kind of care that one takes of their vehicle. Some even resort to dangerous methods, pills, injections that can damage their health. They will work with their shoulders hunched above their computer monitor and walk with their head low and shoulders to the fore.

t have an adequate diet or you live in a polluted atmosphere you simply would probably not be in a position to succeed in your tallest height prospective. The functions of your body will be accelerated so that what works will work better than before. Second, and like Okur before him, Novak gives the Jazz the ability to open up the floor with his outside shooting touch. So never replace your green leafy with fries and chips or you might regret in the end. Drinking plenty of water is also very important if you are on your way to increasing your height.

My search ended when I found an effective way to make sure he can become as tall as he needs to be and without having to use any special medicines. Nevertheless, most of the details is focused on only one element. And of course, you can reach higher than anybody else not to mention to have a bird. The variety of ingredients is mixed in most proportions to maximize their effects. Simply snap kick straight ahead, roughly two feet off the ground.
