Superposition Interview Questions 

Guided by stratigraphic principles (e.g., superposition) largely borrowed from geology, archaeologists have obtained evidence of thousands of years of prehistory from layers of ceramics found on sites all over the world. How were these layers formed? Can't be in the same way as geological layers, where timeframes are much more stretched out!

Geology assumes that over the course of millions of years, the majority of the planet surface has interacted with water (e.g., in some drainage basin, or a rainfall-rich area) or wind. Water and wind make dirt from rocks and move it. It is easy to conceive erosion as the key mechanism creating geologic layers. But in archaeology? Rich ceramic layers only took a few millennia to form even in the most water- and wind-poor locations. So how did the dirt get between the pots? Did God deliberately blow Monte Alban over with dust at the end of each 'ceramic period' so the next one can start parking its garbage over it?

Am I Right About the Sedimentary rock formation?

Sedimentary rocks are formed because of the overburden pressure as particles of sediment are deposited out of air, ice, wind, gravity, or water flows carrying the particles in suspension. As sediment deposition builds up, the overburden (or 'lithostatic') pressure squeezes the sediment into layered solids in a process known as lithification ('rock formation') and the original connate fluids are expelled. The term diagenesis is used to describe all the chemical, physical, and biological changes, including cementation, undergone by a sediment after its initial deposition and during and after its lithification, exclusive of surface weathering.

Sedimentary rocks are laid down in layers called beds or strata. That new rock layers are above older rock layers is stated in the principle of superposition.There are usually some gaps in the sequence called unconformities. These represent periods in which no new sediments were being laid down, or when earlier sedimentary layers were raised above sea level and eroded away.

Sedimentary rocks contain important information about the history of Earth. They contain fossils, the preserved remains of ancient plants and animals. Coal is considered a type of sedimentary rock. The composition of sediments provides us with clues as to the original rock. Differences between successive layers indicate changes to the environment which have occurred over time. Sedimentary rocks can contain fossils because, unlike most igneous and metamorphic rocks, they form at temperatures and pressures that do not destroy fossil remains.

The sedimentary rock cover of the continents of the Earth's crust is extensive, but the total contribution of sedimentary rocks is estimated to be only 5% of the total. As such, the sedimentary sequences we see represent only a thin veneer over a crust consisting mainly of igneous and metamorphic rocks.

... Schrödinger's God? Schrödinger's God is in a superposition of existence and non-existence.

Use the superposition principle to determine an expression for the resultant standing wave. Explain every step and indicate the trigonometric identity used.

y1 = (6 cm) cos (2px - 4pt)
y2 = (6 cm) cos (2px + 4pt)

The answer is y(x,t) = (12 cm) cos (2p x) cos (4pt)

Here's a good example: The law of superposition states that older sedimentary rock layers are always on the bottom of newer layers.
Everywhere we see sedimentary rock layers, we see less complex life at the bottom. As you go higher up, you see more complex animals such as dinosaurs and reptiles. Further up and you will always find mammals with no dinosaurs. I'm talking about fossils of course.

You don't even need to date them as in giving them an age... We know for a fact that older sedimentary rock layers contain less complex life. Newer ones contain more complex life. The evidence is as hard as rock!

25. We have a radioactive isotope - RI-1. It decays and forms daughter element 1- DE-1. The half-life of RI-1 is 12 my (million years). A geologist has used radiometric dating to determine that the rock being dated has an approximate age of 36 my. How many half lives would that represent?
26. Define inferences and be able to identify them.

27. Distinguish between absolute time and relative time. and give an example of each.

28. Give an example of an instrument or method of measuring absolute time?

i don't ask there. it takes a long time to look up all their definitions and try to partially understand what they mean. especially when they use principal of superposition, F=GMm/R squared, HC=71Km/s/megaparsec AND expanding,
if i knew and understood all those things, and all of physics, i probably would be too busy inventing things to be here and probably wouldn't be asking for your opinion greed.

My bio homework is really confusing me. Any help?

31. Which of these pairs of fossils would you expect to find in the same sedimentary strata?
a) trilobites and early mammals c) trilobites and dinosaurs
b) dinosaurs and humans d)dinosaurs and early mammals

1. Explain how the principle os superposition is used by the geologists to compare the ages of rocks.

2. Determine the type of rock that will form in eachof the following scenarios:
a. Lava pours onto the ocean floor and cools.

(I'm really having a tough time with these questions and need help. Tell me the ones you know, if you can't figure out all of the answers. thanks soo much!)

Quantum Physics: The presence of a wave nature in sub atomic particles. The vital difference between a wave and a solid particle is the wave properties of superposition and modulation. Put simply, these properties allow waves of different frequencies to occupy the same space at the same time without direct interaction. Therefore, it is possible for parallel universes to exist separated by a difference in some fundamental wave characteristic.
Michael B. Scott BSc. Graduate in Astrophysics, Edinburgh University
If quantum physics are accepted science, then the possibility exists that when we die we may go there, and from time to time, we see the departed, and maybe they see us.

a note played on a chello string is a superposition of many standing waves resonating on the string as the bow is slid across the string.

Is it real? Do the ideas in the movie have potency? Any ideas of your own on this subject?

Has inventor David Hutchison demonstrated a state of partial or intermediate superposition (superposition means being in many or all places at once) in his experiments with physical objects? Examples of his effects include levitation, jellification of metals, rocks that emit energy beyond the normal range for the type of matter they are constructed of, and movement of large physical objects using electricity....

Which of the following describes the build up and release of stress during an earthquake?
the Modified Mercalli Scale
the elastic rebound theory
the principle of superposition
the travel time difference

according to shrodinger equation and uncertainty principal, we have a wave function evolve over time, if we have an observable, and know the real part, we can reason the imaginary part of one qubit to be both up and down with two superposition, assuming the qubit is in two dimensions, and extended to multiple qubit system, the uncertainty principal tell us, when all real part is determined, the imaginary part could be the combination of all, thus it takes the tensor product of the all possibility, and have 2^n possibility
however, i have been having a doubt, and due to some reasons, maybe having something to do with decoherence, maybe not, i am not so sure
1)if one given qubit is determined(that is objective certainty, subjective uncertainty simply is the matter we do not know how it is certainly there), the second will shorten its space of possiblity, and the chance of one spin up/down is higher than down/up is more deterministic very little bit(trivial but not none)
2)once the first moment is determined, the chance the second moment is shortened very little bit
in this way, some superposition cannot happen, some happen more frequently than some others, thus i doubt the possibility of quantum computer, particularly if it is a truly practical quantum computer,with thousands or even millions of qubits
does anybody have any idea about that

I'm really, really bad at science, and I just don't get this... at all. Can somebody answer these questions?
