Internet has many uses in my life - I use it for studying, tracking weather, playing games, watching movies and listening to music. I mostly use internet in my smartphone. It's more convenient to carry around rather than a computer. At home i prefer my computer it makes studying alot easier as I can type words much faster than with a smartphone or a pen. It's also bigger so it's nice to watch movies with as well. I use my computer a lot less than my phone maybe 2 or three hours a day, whereas I use my phone at all times. - , , , . . , . - , , . , . , - , 2 3 , .

Does the Higgs Field do something? Dmitri Martila ([email protected]) Latter affiliation: Tartu University (Dated: September 16, 2016) Abstract Is studied the possibility to replace the Dark Matter and the Dark Energy with the single Higgs Field (or fields). The study in close direction was made in arXiv:1603.06242, and in “The Higgs Boson May Disintegrate into Dark Matter” (the Google News). Just because the physics is physical, then the Higgs Field do exist, do exist throughout the spacetime, and even acts on curvature of the spacetime even in the cosmic void (the places without the baryonic matter). In case of the places with the baryonic matter the Higgs Field emits the Higgs Boson to give the baryonic matter the right amount of mass: therefore the density of the Higgs Fie...

The French education system is split into three stages: primary school (école), secondary school (collège) and high school (lycée). Primary and secondary education is free, neutral, secular and compulsory between the ages of 6 and 16. However, there are some private schools that are not subject to these obligations and particularities of the French education system. Nursery school classes accept toddlers at 2 or 3 years of age, starting in September. The children develop their basic faculties, improve their speaking skills and are introduced to the world of reading and writing, numbers and other key areas of learning. From age 6 to 11, the children attend elementary school which is mixed and freein the case of public (state) schools. The 'collège' accepts all pupils after elementary school without the need to pass an entrance exam. The teaching is structured by subject: French, mathematics, history-geography, 'civics' or civil education...

Iron Man essay A superhero is a character with extraordinary powers who is dedicated to protecting the public. However, this definition can be matched with different sets of character traits. This essay discusses what makes Iron Man special and memorable. Besides literally being strong, which a superhero obviously needs to be, Iron Man aka Tony Stark was also highly intelligent. That's what actually helped him in most situations rather than mindlessly beating the opponent. Tony Stark had graduated with advanced degrees in physics and engineering at the age of 17 from Massachusetts Institute of Technology. When imprisoned and forced to create a weapon of mass destuction in the movie Iron Man, Stark was able to build an armor suit and a reactor to escape. His extensive knowledge about quantum mechanics and artificial intelligence helped him to produce a new e...

1 Wave energy Introduction to wave energy There are several possibilities to harvest different forms of energy from the sea. One of these options is the usage of waves for the generation of electricity. The devices needed to perform this task are called wave energy converters. Wave energy is indirect solar energy in twice. At first there is the wind, which is caused by variations in atmospheric pressure due to a differential solar heating of earth's surface by the sun. Different regions of pressure drives a force which rises a movement of atmospheric air masses that causes the earths wind system. If wind strikes over the surface of an open water, waves are induced. First they are very flat with only a low level of energy. When there is a long distance over the water on which wind can attack the small ones, they became bigger and bigger with a l...
1.Mis on aine? Aine on aatomite kogum, mis on pidevas soojusliikumises; ainel on agregaatolek ning füüsikalis-keemilised omadused. Aine all mõistetakse füüsikas tavaliselt stabiilseid seisumassiga elementaarosakesi (tavaliselt prootoneid, neutroneid ja elektrone) ning nende kombinatsioone. Selliselt mõistetuna vastandatakse ainet väljale. 2.Kuidas tõestada, et ained koosnevad osakestest? Erinevate katsete tegemisel, ntks. lõhna/värvi levimisel (difusioon - nähtus, kus ained segunevad üksteisega. Sama moodi on difusioon ühe ja sama aine molekulide tungimine teise aine molekulide vahele; difusioon on soojus liikumisest tingitud protsess, mis viib kontsentratsiooni ühtlustumiseni ruumis). 3.Kuidas tõestada, et aatomid ja moleklulid on pidevas soojusliikumises? Reaktsioonide toimumise tõttu. Aineosakesed on pidevas soojusliikumises, selle kiirust mõõdame me kaudselt termomeetriga. Kui jahutada kehasid siis aineosakeste soojusliikumine aeglu...
Sissejuhatus Neptuun on kaheksas ja viimane suurtest planeetidest meie päikesesüsteemis ja on eriti kuulus oma avastusloo poolest. Mõõtmetelt on Neptuun väga lähedane Uraanile: läbimõõt 0,96, mass 1,2, tihedus 1,3 Uraani omast, välimus on ka sarnane. Kaaslasi on Neptuunil kaks: Triton ja Nereis. Ilmselt hakkab peake Neptuuni Päikesesüsteem lõppema. Oma nime on ta saanud Vana- Rooma merejumala Neptuuni (Kreekas: Poseidoni) järgi. Neptuuni sinine värvus on punase valguse neelamise tulemus metaani poolt atmosfääris. Neptuuni omadused Keskmine kaugus päikesest on 4497 miljonit km. Asub maast 63 valgusaasta kaugusel. Ligikaudne läbimõõt 49528 km. Tiirlemisperiood 164.8 maa aastat, diameeter 49 532km, mass 1,0234*10 astmel 26. Pöörlemisperiood 16 tundi ja 7 minutit. Avastamine Neptuuni asukoha arvutas välja prantsuse matemaatik Urbain Le Verrier, püüdes seletada häireid Uraani liikumises temast kaugemal asuva planeedi gravitatsioonil...

TALLINNA TEHNIKAÜLIKOOL, FÜÜSIKAINSTITUUT 19. DIFRAKTSIOONIVÕRE 1. Töö eesmärk Valguslaine pikkuse, difraktsioonivõre nurkdispersiooni ja lahutusvõime määramine. 2. Töövahendid Goniomeeter, difraktsioonivõre, spektraallamp. 3. Töö teoreetilised alused Valguslainete levimist tõkete taha homogeenses isotroopses keskkonnas nimetatakse valguse difraktsiooniks. Difraktsiooni tõttu satub valgus geomeetrilise varju piirkonda. Difrageerunud valguse edasisel levimisel täheldatakse interferentsi, mille tulemusena valguse intensiivsus on erinevates ruumipunktides erinev. Intensiivsuse jaotuse ava või tõkke taga määrab valguse lainepikkus ja ava või tõkke kuju ning suurus, samuti vaatluskoha kaugus avast või tõkkest. Antud töös tekitatakse difraktsioonipilt korrapärase (perioodilise) pilude süsteemi, nn difraktsioonvõre abil, milles maksimumid on märgatavalt intensiivsemad ja kitsama...

Tallinna Lilleküla Gümnaasium WOLFGANG ERNST PAULI referaat Ester Alasalu 12a Tallinn 2010 Sisukord 2 Sissejuhatus Teemaks on valitud kuulus teadlane Wolfgang Ernst Pauli, sest tema kohta ei ole väga palju teada. Töö on oluline, sest füüsika on kiirelt arenev ala ja seetõttu on tähtis pidada meeles neid teadlasi, kes on avastanud ja kirja pannud füüsika alustalad. Wolfgang Ernst Pauli on kindlasti üks neist ja on väärt teada tema kohta rohkem kui koolitunnis mainitakse. Töös keskendutakse teadlasele kui inimesele, on mainitud tema perekondlik taust ja isiklikud suhted, loomulikult on kirjutatud ka Pauli avastustest, mis ta füüsikalukku kirjutanud on. 3 Wolfgang Ernst Pauli elulugu Wolfang Ernst Pauli sündis 25.aprillil aastal 1900 Vi...
Summary • Early history of translation studies – Cicero and St. Jerome (what did they do/how/why are they relevant to translation studies?) St. Jerome – Greek scholar, did some translation work. Lived during the 4th century. Jerome is best known as the translator of the Bible into Latin. A previous version (now called the Old Latin) existed, but Jerome's version far surpassed it in scholarship and in literary quality. Jerome was well versed in classical Latin (as well as Greek and Hebrew), but deliberately translated the Bible into the style of Latin that was actually spoken and written by the majority of persons in his own time. This kind of Latin is known as Vulgate Latin (meaning the Latin of the common people), and accordingly Jerome's translation is called the Vulgate. Cicero – Lived during the 1st century BC. Roman politician, philosopher & translator. Theory ‘‘word-for-word’’ & ‘‘sense-for-sen...
Funktsionalism - Under the influence of Darwin, the school of functionalism stressed the role of conciousness and behavoior in adapting to the enviroment.

All about High Tech High tech is technology that is at the cutting edge--the most advanced technology currently available. There is no specific class of technology that is high tech--the definition shifts over time--so products hyped as high tech in the 1960s would now be considered, if not exactly low tech, then at least somewhat obsolete. This fuzzy definition has led to marketing departments describing nearly all new products as high tech. Economy Because the high-tech sector of the economy develops or uses the most advanced technology known, it is often seen as having the most potential for future growth. This perception has led to high investment in high-tech sectors of the economy. High-tech startup enterprises receive a large portion of venture capital. However, if, as has happened in the past, investment exceeds actual potential, then investors can lose all or most of their investment. High tech is often viewed as high risk, but...
