Theoretical Physics

Iím sometimes asked why I like physics.  I guess it sounds like a nerdy thing to be into but there is a beauty to the universe that I canít help but think about all the time.  Philosophy and physics frequently come up in the same context.  I like to think that physics holds the true answer to all of lifeís questions but Iím frequently reminded in my studies that there are real boundaries between what is understood about the physical world, what the possibilities are and what conclusions can be drawn from it all.  The reality of the world we live in is truly mysterious and in my mind it would be a sad day indeed if all those details were understood "in toto".  There's something romantic and thought provoking about the exploration of the unknown.

When I was a sophomore in college I'd decided to study computer science and as a result I ended up taking more math than I thought I'd ever have to think about.  To my surprise it wasn't impossible to learn and through sheer repetition I found that it had real-life, tangible meaning when applied to physics.  I never took a physics class in college but found a copy of Einstein's 1905 paper called On the Electro Dynamics of Moving Bodies. I could not understand a single concept in that paper but later when I took calculus some of the problems were concerning the mathematics of motion and that gave me the life-long passion for studying those concepts that I could not understand.  It's a gradual process and knowledge is fleeting.  The more you mull the ideas over in your mind the more you understand.  If you stop thinking of it, you slowly lose the knowledge you've gained.  Ireckonits the same in all disciplines of thought.  Do not be discouraged by the things you do not understand.  To paraphrase Feynman, everything that is Writeable-Downable is understandable. 

Iím definitely no physicist.  At best Iím a physics historian because I do no work to advance physics on my own.  Iím content to read and try to understand what is already known.  The field is complex and I keep working on it when I can find the time.  I figure Iím no more than 75 years behind.  Its difficult to make progress because I donít get to hang around and converse with physics dudes.  I hang around and talk to computer dudes and none of them are interested in physics.  If you happen to stumble upon this website and have a true knowledge of the subject of physics, I would love to receive comments concerning anything that Iím blatantly wrong about.  I want the knowledge and I want to help others understand.  It does nobody good if Iím writing bullshit thatís simply not correct.

This is a pretty interesting thing about a lawsuit by some people that are concerned that the new particle collider at CERN is going to destroy the earth.  haha  http://cosmiclog.msnbc.msn.com/archive/2008/03/27/823924.aspx 

This is an absolutely cool animated video about the famous double-slit experiment in physics.  This illustrates the bizarre things we see in quantum physics:  http://www.youtube.com/watch?v=DfPeprQ7oGc&feature=related

(Color?) This site has so many names.  Lots of research possibilities.

An interesting person this is dude.  Protagoras Seems to be thinking appropriately about real life.  1)Surely Man is the measure of all things. If ya take it literally which he most surely meant, it would freak me out to make any sort of nuance-type of observation of non-human measuring.  Sometimes you think you see it but then it turns out that a 6-sided honeybee comb is a happenstance occurrence because 6 same sized circles fit PERFECTLY around another circle of the same size.  They simply have to make all their circles the same size.  Those bugs can count their chomps!  That's pretty miraculous but most people just don't notice.  Perhaps they expel the same volume with each chomp.  2) I can sometimes make something sound better than it really is; usually when I'm trying to explain MY point of view.  3)  Hard to argue that one.  Literally!  I could get in bad trouble there.  I have my beliefs.  Its a combination of everyone of you that I've talked to in my life.  So don't look at me for answers on that.

Here's an interesting story about scientist imaging electrons for the first time. http://www.msnbc.msn.com/id/23336318/

Why did the chicken cross the road?
Aristotle: It is the nature of chickens to cross roads.
Isaac Newton: Chickens at rest tend to stay at rest, chickens in motion tend to cross roads.
Albert Einstein: Whether the chicken crossed the road or the road moved beneath the chicken depends on your frame of reference.
Werner Heisenberg: We are not sure which side of the road the chicken was on, but it was moving very fast.
Wolfgang Pauli: There already was a chicken on this side of the road.

What's New! 

April 4, 2010 - It's mum's birthday today. 

March 24, 2010 - Updated notes.  Changed Dory's name away from Stuka.

March 13, 2010 - Added a picture of Stuka on the home page and I've added the source code to my projection program.  Of course I also updated the daily notes as well.

March 10, 2010 - Updated notes and updated the section on Rotations.

March 6, 2010 - I added to the daily notes. 

February 24, 2010 - I added some links on the front page and updated the link archive.  Updated notes.  Today was no fun.

February 15, 2010 - I wrote on the Quantum page tonight and updated my daily notes.
