I am my dad's personal Yahoo! answers person when it comes to things science and physics. So when I received a question on the dual nature of light and matter, I wrote him back a nice long (LFP!) email in answer. I thought I'd share. Question: Sound travels in waves and needs an "ether" for transmission. Light is also a wave but doesn't need an ether. Is light in space "wave" or "particle"? because when light bends do particles bend or this this one of the examples of light as wave? Answer: Sound is a pressure wave. It is the compressing of molecules. It is the compression that is the sound. Light is a wave of electromagnetic fields, fields in this case being force representations. The light wave is a constant of nature in which a electric force changing will produce a magnetic force which will cause an electric force in a stable, repeating way traveling forward. There are other places where electricity creates magnetic forces and v
So, The University of Arizona basketball team is coming to Los Angeles this weekend to play USC and UCLA. Its been a tradition of our little AZ clique to go to the games for the last 5 years. However, UofA was a pretty good basketball team the majority of those years. Now with Rodgers gone, out of the top 25 rankings for the first time in 7-8 years, and Lute giving the kibosh on 3 point attempts (he should just tell Radenovich to stop shooting) things are swinging back into the LA team's favor. Which brings me to the issue of tailgates. It would be nice to actually have a truck to go to the basketball games and put the tailgate down and sit and have a few beers and kick back. Well, I used to be able to do that. Alas, as bad luck would have it (with the help of a few boys from a local chop shop ) my tailgate on my pickup truck was stolen clean. In the place where I park my truck at night. I mean, I see CLKs, H2s, m3's and all sort of $$$ MB cars next to mine. And they have
The webcomic xkcd was recently featured on a popular tech website which I frequent . The author spoke at mit about his life and writing (and was interuppted by students ), so I started reading the comic. Man, is it good. I just started reading them, and got lots of the way through. Then I realized that there is a second level of awesome, in the img alt text tags. And then I read most of them again. Some of my favs, in no particular order: http://xkcd.com/c181.html - Interweb Net Codes! http://xkcd.com/c113.html - Zeta Functions 4 Pres! http://xkcd.com/c128.html - :-( http://xkcd.com/c132.html - 4 d3w4rd <img alt="how many links is he going to inline?!" src="./holla.jpg">
