Well I haven’t been writting much since I was very busy with a take-home midterm we got, plus we had bunch of Navy guys come in for a review at work, so I had to spend a lot of time on that as well.  Now the things are quiet again.  I turned in the midterm today and took the day off, so decided to go to Issana’s work place. It’s a little farm in Bellevue next to Kelsey Creek Park.  It’s free admission and anyone can just walk in and take a look at the animals, most of which you can pet as well.  I did some picture taking there so check it out in my photos section or click here.

Tomorrow I’m off to a cheese festival and then I should be making some Bosnian pies.  I hope they come out good, it will be my first time making my own philo dough.  I should also continue my plasma posts tomorrow.

So in previous post I defined what plasma is and today I will define some additional criteria that are required for plasma formation.  These criteria are necessary to distinguish between an ionized gas and plasma itself.  Before we do this we need to define the quantity known as Debye length which is the measure of the shielding present in plasma.  This type of shielding is called Debye shielding. What happens inside the plasma is that we have a lot of positively charged particles (ions) and negatively charged particles (electrons) floating around.  If we insert a positively charged sphere into the plasma all of the electrons would rush to it and neutralize the charge.  So we would end up with our positive sphere and a bunch of electrons right around it and the number of electrons would be equal to the charge required to neutralize the positive charge.

As I mentioned couple of days ago I will be going trough my plasma books and witting about things I go over.  So start of the first post I guess I should give a brief introduction to plasmas.

Currently there are four know states of mater, plasma is one of them.  Most people are familiar with solid, liquid and gaseous states of mater, but very few people know much about plasma.  It is said that about 99% of all matter in universe is in plasma state, yet on Earth we see very little plasma.  This is because the thing that makes mater transition from one state to next is temperature.  In the case of water ice is the solid state and it occurs when temperature is below 0C, liquid water occurs between 0-100C and above 100C is vapor or water’s gas state.  In order to make water into plasma we would have to raise the temperature of the water to thousands of degrees, which is very impractical here on Earth, but on Sun and billions of other stars it’s a completely different story.

I’m finally back here.  Work and school were uber busy last few weeks and I’ve had a lot of side things going on that I really didn’t have an urge to sit down and write things.  I’ve done some small changes to the website though, like adding few small details as well as a LaTeX editor.  This is my plan to start writting some plasma physics things on here.  I need to get ready for my qualifying exam and the best way would probably be to go trough some of the books I have start to end.  While going trough them I will be writting posts about whatever it is that I’m reading.  Hopefully this will reinforce my learning and at the same time preserve some of that information on the web.

Besides all this I’ve been doing a lot of running.  I average about 5-6 miles a day, but I’ve ran a few 8-10 mile runs as well.  I’m looking for 5K runs all the time so let me know, all I need is a day notice.  If it’s a 10K run then I will need 2-3 days so that I can adjust my daily running schedule.  In June I’m hopping to do my first half-marathon, but with $100 entry fees I’m not sure if that’s going to be worth it.  Let me know if you know of any cheaper ones.

It has been while since I’ve written anything, but life has been pretty busy.  I’m finally getting finished with Rex’s photos and I should have them up here over the weekend I hope.  There will be a new watermark that I will be adding to all of my photos in the future.  This way I’ll get a bit more exposure.  Main reason why I don’t update as much is that I just didn’t have much time.  I’ve been doing a lot of busy things, from work, school and hanging out with people I’ve been looking for some free time just for relaxation and not writing blogs.  Hopefully I’ll start a bit of plasma physics writing, but until then I leave you with one of the cutes pictures yet:
