What did max plank do?
Max Planck invented the quantum theory of black body radiation and modern physics.
What are Stephen Hawking's discoveries?
he discovered that by using quantum theory and general relativity he was avle to show that black holes can emit radiation.
What is hawking radiation?
Hawking radiation is black body radiation that is predicted to be released by black holes.It is due to quantum effects near the event horizon.According to the quantum mechanical uncertainty principle, rotating black holes should create and emit particles. Black holes that lose more mass than they gain through other means are expected to shrink and ultimately vanish. Hawking radiation reduces the mass and the energy of the black hole and is therefore also known as black hole evaporation Micro black holes (MBHs) are predicted to be larger net emitters of radiation than larger black holes and should shrink and dissipate faster. Black holes are sites of immense gravitational attraction. Classically, the gravitation is so powerful that nothing, not even electromagnetic radiation(including light), can escape from the black hole. It is yet unknown how gravity can be incorporated into quantum mechanics, nevertheless, far from the black hole the gravitational effects can be weak enough for calculations to be reliably performed in the framework of quantum field theory in curved spacetime. Hawking showed that quantum effects allow black holes to emit exact black body radiation, which is the average thermal radiation emitted by an idealized thermal source known as a black body. The electromagnetic radiation is as if it were emitted by a black body with a temperature that is inversely proportional to the black hole's mass.
When did Max Planck formulate the quantum theory of physics?
He published his work in 1900. It was VERY FAR from a full quantum theory, it was only an attempt to explain the spectrum of black body radiation with the idea that light came in chunks he called "quanta." And he himself did not think these quanta actually existed, he only noted this as a mathematical curiosity.
What made stephen hawking famous?
his amazing discoveries in black holes and quantum theory

What is planks quantum hypothesis?
That light comes in indivisible chunks (he called them "quanta" but the present term is "photons") and that the energy of each such quanta is equal to the frequency of that light times a constant (now called Planck's Constant). When Max Planck first proposed this idea in 1900, he only noted it as a mathematical curiosity that would permit a solution to the spectrum of black-body radiation. In other words, he didn't assert that it was actual description of reality. In 1905, Einstein noted that this same assumption would fully explain the photoelectric effect.
What has Stephen hawking discovered or invented?
a theory on how black holes exert radiation
Light produced when a black hole decays is called?
A type of weak radiation thought to be present due to quantum effects near a black hole's event horizon is often called Hawking radiation, after the scientist who proposed it, Professor Stephen Hawking.
How do electrons move in and fill the orbitals and levels according to modern quantum theory?
Because I'm good at black ops 2
What did Stephen hawking say about black holes?
His major contribution to the theory of black holes is that they will gradually evaporate, due to certain quantum effects close to the event horizon.
What is Stephen Hawking's theory of black holes?
This is far to extensive a subject to be covered here and quite beyond the ability of most people to understand and explain. However Professor Hawking has theorised that even black hole can 'evaporate' by means of Hawking radiation. This will however take a great deal of time. The bigger the hole the longer it will take.
