I need find he coefficients C2 and C1 from the wavefunction
PSI(x,0) = C2 |2> + C1 |1>

for harmonic oscillator of mass m and frequency w

|2> and |1> are normalized eigen functions for n = 2 and n = 1

Find the coefficients C2 and C1 such that the expectation value for the total energy, for |PSI(x,0)> equals = 2(h bar)w

and also...
Write the expression for the time dependence of PSI(x,t)
Calculate the probability to find system in state |2> as a function of time

Calculate as a function of time
Calculate as a function of time

Whatever help is possible is GREATLY appriciated.

why do modern engineers & scientists prefer binary number system to other number systems although we have so many number systems & most importantly binary number system is not found in nature? Secondly, although the human mind can comprehend much higher(read: more complex) number systems then why can't we design digital systems on such higher platforms?.... I mean what are the discrepancies in other number systems?

Into the past, into any moment in your own life.... What secret of the future would you whisper into your own ear; What nugget of future information would you pass on to your former self? Would you try to warn of danger, or make yourself rich? Or just say hi?

Is there another planet that life exists? Are there life forms greater than us, as Steven Speilberg speaks? Are UFOs a fact or a fiction? Are there real evidences that life forms [aliens] from outerspace exists? are there sitings about this so called aliens? Or all of these are just a mere imagination of a human being?

Evolution assumes that man dropped out of the trees 1 to 5 million years ago and became fully human approximately 100,000 years ago. Yet archeological records show civilization arising only about 5,000 years ago (based on evolutionary thinking). In other words, by evolutionary reasoning, it took mankind 95,000 years after becoming fully human to figure out that food could be produced by dropping a seed into the ground! It has been estimated by evolutionary anthropologists that the earth could have easily supported 10 million hunter/gatherer type humans. To maintain an average of 10 million people, spread over the entire plane, with an average life span of 25 years, for the last 100,000 years . . . .would mean that 40 billion people had lived and died. Archeological evidence clearly shows that these "stone age" people buried their dead. Forty billion graves should be easy to find. Yet only a few thousand exist. The obvious implication is that people have been around for far less time.
