Albert Einstein (1879 - 1955) was a German theoretical physicist who needs no extra introduction for any basicaly educated person.
As developer of the theories of special and general relativity he actuated a revolution in physics, and is often regarded as the father of modern physics. In general Einstein is considered the most influential physicist of the 20th century.
While best known for his mass-energy equivalence formula: E = mc2, Albert Einstein received the 1921 Nobel Prize in Physics for his discovery of the law of the photoelectric effect. This discovery was essential in establishing the quantum theory. In spite of the fact that with his work he even provocated further development of the field of quantum mechanics, he was displeased with its results: "God doesn't play with dice."
In the photoelectric effect, electrons are emitted from matter (metals and non-metallic solids, liquids or gases) as a consequence of their absorption of energy from electromagnetic radiation of very short wavelength, such as visible or ultraviolet radiation. Electrons emitted in this manner may be referred to as photoelectrons.
Photovoltaics is a method of generating electrical power by converting solar radiation into direct current electricity using semiconductors that exhibit the photovoltaic effect. Photovoltaic power generation employs solar panels composed of a number of solar cells containing a photovoltaic material.
But the path towards photovoltaics was long and full of confusions. The photoelectric effect was first observed and documented by Hertz in 1887, but understood only in 1905, when Albert Einstein introduced idea that light can be described as light composed of discrete quanta, now called photons, rather than continuous waves. Based upon Max SOMEBODYS's theory of black-body radiation, Einstein theorized that the energy in each quantum of light was equal to the frequency multiplied by a constant, later called SOMEBODY's constant. A photon above a threshold frequency has the required energy to eject a single electron, creating the photoelectric effect.
To find this ECOLOGICAL CACHE you have to solve following puzzle.
1.) Find out the word for family name SOMEBODY and determine the sum of the positions of the letters in english alfabet if
a=1, b=2, ..., and z=26.
Sum = A.
2.) Complete the following equiation where letters are single digits:
EPhoton = B,CD x 10-34 [Js] x W
(W - stands for 'omega' = angular frequency)
3.) Calculate the final coordinates of the cache:
aaa = A x (D+C-B) x (D - 2 x B) + (21+A)/(2 x B)
bbb = (2 x B + D) x A + (A - 3 x D)/(2 x B)
N 45° 57,aaa
E 14° 39,bbb
At cache location look to the East to see photovoltaic at work.
Happy caching.
Pot do uporabne fotovoltaike je bila dolga in polna napačnih zaključkov. Fotoelektrični efekt je prvi opazil in dokumentiral Hertz že leta 1887, vendar je bil pojav razumljen šele leta 1905, ko je Albert Einstein predstavil idejo, da je svetlobo možno opisati s posameznimi diskretnimi paketi oziroma kvanti, sedaj imenovanimi fotoni, namesto z neprekinjenimi valovi. Temelječ na teoriji sevanja črnega telesa Maxa NEKOGA, je Einstein izpeljal zaklkjuček, da je energija vsakega kvanta svetlobe enaka njegovi frekvenci pomnoženi s konstanto, danes imenovano NEKOGARŠNJA konstanta. Foton s frekvenco nad določenim pragom ima zadostno energijo, da izbije elektron in povzroči fotoelektrični efekt.
Ta EKOLOŠKI ZAKLAD boste našli z rešitvijo naslednje uganke.
1.) Poiščite besedo za priimek NEKOGA in določite vsoto pozicij črk v angleški abecedi, če je
a=1, b=2, ..., in z=26.
Sum = A.
2.) Dopolnite naslednjo enačbo, kjer vsaka črka predstavlja enomestno številko:
EPhoton = B,CD x 10-34 [Js] x W
(W - je t.i. 'omega' = angularna/kotna frekvenca)
3.) Izračunajte koordinate zaklada:
aaa = A x (D+C-B) x (D - 2 x B) + (21+A)/(2 x B)
bbb = (2 x B + D) x A + (A - 3 x D)/(2 x B)
N 45° 57,aaa
E 14° 39,bbb
Na lokaciji zaklada poglejte proti vzhodu, kjer boste videli fotovoltaiko na delu.
Prijeten zakladolov.
