I have been reading a lot of article lately, all which are so interesting that it causes a dilemma for me or rather which path should I take, there's so many field i wanna explore, is it from the maths perspective, is it from the physic perspective or is it from the chemistry perspective??? or why not from every angle??? do I have enough time??? arg!!!!
Here are some interesting title:
1)Feelings Of Hopelessness Linked To Stroke Risk In Healthy Women
2)Immune Defect Is Key To Skin Aging
3)Taking Up Music So You Can Hear
4)Trifid Nebula: A Massive Star Factory
5)New Way To Reproduce A Black Hole?
so after reading the article, I will definately fo wiki and find out more about the terms, this definately help me to study more or rather irrelevant study but somehow help me to study my papers better as well. Dun know why I'm saying this??? then this is just a random post : )
U ever wonder about aurora in the skies??/ here your chance to find out more.
"Males Of High Genetic Quality Are Not Very Successful At Fertilizing Eggs
ScienceDaily (Aug. 8, 2009) — Contrary to predictions, males of high genetic quality are not very successful when it comes to fertilizing eggs. A new study on seed beetles by Swedish and Danish scientists Göran Arnqvist and Trine Bilde shows that when a female mates with several males, the males of low genetic quality are the most successful in fertilizing eggs.
In almost all animals, females mate with several different males, despite the fact that a single mating is often sufficient to fertilize her eggs. Multiple mating also carries costs to females, such as the risk of catching sexually transmitted diseases. One commonly held belief is that this behaviour may allow females to choose the sperm of the male with highest genetic quality to fertilize her eggs. Professor Göran Arnqvist from the Department of Ecology and Evolution, Uppsala University and associate professor Trine Bilde from the Department of Biological Sciences, University of Aarhus, have tested this possibility directly for the first time and shown that it is not true.
Their study on seed beetles shows that, contrary to predictions, males of low genetic quality are more successful in fertilizing eggs. Males who gained the highest share of paternity were actually males with low genetic quality. These males also fathered offspring that did less well.
"The results support the suggestion that genes that are good for males may often be bad for their mates. Therefore, in beetles at least, multiple mating does not award females with genetic benefits," says Göran Arnqvist.
The study is published in the June 26 issue of Science"

Fluid Dynamics Class Inspires College Student To Develop 'Plasma Paddles'
http://www.sciencedaily.com/videos/2007/1112-creating_a_21st_century_video_game.htmThis is a game development by some student that become a smash hit overnight.
Gonna download this game.
Another game that I saw my friend play which looks like fun is plant vs zombie.
Everytime you get stuck you just don't wanna think anymore cuz it hurts... and slowly by slowly you train your mind not too think anymore. When I'm not doing any work, I just dun wan to think anymore. Everytime I think, it just remind me of my inability to to my assignment, my inability to focus, not being good enough. Damn it!!!!
But I can't let this go can't I....... I will challenge my self to the very end no matter what. Fight all the way, everyday. Dun care what ppl think!!!! Through primary school, high school, college, you see so many ppl who don't make it, I wish i could do more for my friends. You start something, you must follow through no matter how chaotic it is and finish it. In the midst of chaos, there will be light.
This is related to chaos theory. Put in simply, things that have a hard pattern to predict (like water dripping from a tap) falls into the lorenzo's rings, instead of being able to predict, its more like that the water dripping pattern would fall into the range. So you't can't accurately predict but can have a probability guess but it will be within range.
In the midst of chaos, there will be you there standing and eventually fall out of the tap and into a place where we suppose to go in the first place. I will do better and be able to tell them to get up and move forward cause I did that as well.
"In the midst of chaos, there you are."
Guiding Light Around
Corners With New
Metamaterial Device
ScienceDaily (Aug. 1, 2009) — Using a composite metamaterial to deliver a complex set of instructions to a beam of light, Boston College physicists have created a device to guide electromagnetic waves around objects such as the corner of a building or the profile of the eastern seaboard.
As directed by the researchers' novel device, these beams continue to behave as if traveling in a straight line. In one computer simulation, Assistant Professor of Physics Willie J. Padilla and researcher Nathan Landy revealed the device could steer a beam of light along the boundary of the US, stretching from Michigan to Maine, down the seaboard, around Florida and into the Louisiana bayou, according to research published in the research journal Optics Express.
The researchers accomplished their feat by developing a much more precise set of instructions, which create a grid-like roadmap capable of twisting and turning a beam of light around objects or space. Their discovery is an extension of earlier metamaterial "cloaking" techniques, which have conjured up images of the Harry Potter character disappearing beneath his invisibility cloak.
Padilla and Landy report developing a space-mapping technique that delivers greater precision and efficiency guiding light along pathways that previously were too complex to sustain – from 90-degree angles to the rugged coastal profile of Maine. Furthermore, they've built this new device using relatively common dielectric materials, such as silicon.
"Our method combines the novel effects of transformational optics with the practicality of dielectric construction," Padilla and Landy report. "We show that our structures are capable of guiding light in an almost arbitrary fashion over an unprecedented range of frequencies."
The discovery builds upon a decade-long revolution in electromagnetics brought about by the emergence of metamaterials. Constructed from artificial composites, metamaterials have exhibited effects such as directing light at a negative index of refraction.
Researchers have combined metamaterials with artificial optical devices – also known as transformational optics – to demonstrate the "invisibility cloak" effect, essentially directing light around a space and effectively masking its existence. In addition, other researchers have used a method known as quasi-conformal mapping and very complex metamaterials to issue a somewhat imprecise set of instructions that create another space-cloaking effect.
