Hi!

Oh boy! I have a quantum mechanics examination tomorrow. Here is a small part of the QM-machinery I need.

Well, 4 hours and 5 problems. It went not too bad but maybe not too good also. One has to be a Guru to do 5 QM problems in 4 hours...

It took you four hours to do 5 problems! tsk tsk...... such easy problems too... LOL.. JK. I hope that it went well Henri.

Thanks, Mr. Majestic. :) Yes, maybe I pass the course. LOL. Can't be too sure before seeing the points, though...

Hi Henri T.H.
How was the test result?
I took this year one subject to build up my university credits: History of Physics.
I am scared because it is far more difficult than the usual stuff I had before. Some added difficulty is the subject is not virtually monitored by anybody, so it is all up to me! No other alumni to ask to.
Cheers.

4 hours for 5 problems brings back memories of my nightmares with introductory physics in college. I never finished all the problems on a physics test. No subject humbled me more than physics. I definitely could not have majored in physics. Very interesting subject though.

Didn't they give the usual part A or part B test?

Part A derive the universe. Make no assumptions, show all calculations.

Part B

We need to patch up the LHC and do at least another 10 years or so to dip into the next Pandora's box for that!

Are Milkyway@home and Cosmology@hame good enough approximations for an answer?

You do know that Milkyway doesn't study the Milkyway; it studies BOINC. Read their home page. "Milkyway@home is based at the Rensselaer Computer Science Department. This particular project is being developed to better understand the power of volunteer computer resources."

And their page reads:

Milkyway@home is a research project that uses Internet-connected computers to do research in modeling and determining the evolution of the Milkyway galaxy. You can participate by downloading and running a free program on your computer.

Milkyway@home is based at the Rensselaer Computer Science Department. This particular project is being developed to better understand the power of volunteer computer resources.


(My emphasis.)

So, they are not doing as stated in the first paragraph? I can well expect that the project is also viewed as a 'test-bed' to see if Boinc works.

Looks like they've opened up their code and they are already reaping the benefits and angst of optimising the code

To answer the question: Is it based in their astronomy department or the computer science department? Might also read the four links just below the second paragraph.

Sorry, I don't understand your question and the implied concerns...

Milkyway@home looks to be studying star streams in our galaxy and in developing further code for doing more of that. That particular project looks to be one project amongst various other projects that the supporting dept does research for.


Your concern is?

Happy crunchin',
Martin

The concern is that people may not understand they are developing software to do research, not doing new astronomy, at least today. Not that developing software isn't important.

Hello! How are you doing?
Well, this new subject requires far more attention than all the others, because they are not really relatives to my main subject!!It is a subject for the last half part of the university year, that means, exams will be held in June ´09, but I need to prepare them as soon as possible. I am finding some difficulties on getting the right books to read: they seem to be scattered around and hidden!!!
But I have started with an interesting one: "A brief history of time: from the Big Bang to black holes" by Stephen Hawking.
I thought I would take it easy at the beginning!....with nice illustrations which makes the reading more enjoyable.
Cheers!
Keep on trying!
