Particle Accelerator

A "particle accelerator" sounds like it'd be a contrivance straight from a sci-fi novel, because most of us don't really quite understand how they work. But some of us know, how The Flash got his powers from an explosion caused by the particle accelerator,and the Meta-Human thesis etc. Having mentioned all that, Particle accelerators are real, and they're used by physicists all over the world to investigate the structure of atomic particles. The largest one in existence is the Large Hadron Collider (LHC),
located under France-Swiss border near Geneva. But its not the first, In fact particle accelerators have been around since 1930s, although in smaller sizes compared to LHC.
'A particle accelerator is a machine that uses electromagnetic fields to propel charged particles to nearly light speed and to contain them in well defined beams. Large accelerators are used in particle physics as colliders, or as synchrotron light sources for the study of condensed matt…

Shape Memory Alloys- An Insight

To understand the importance of this topic, first we need to know it’s practical use and other applications. Shape memory alloys (SMAs) are an unique class of multi-functional materials that have the ability to recover large deformations or generate high stresses in response to thermal, mechanical and electromagnetic stimuli.They display two distinct crystal structures or phases: Martensite and Austenite. Determination of their phase depends on temperature and internal stresses (which play a part in super-elasticity). Martensite exists at lower temperatures and Austenite at higher temperatures.When a SMA is in Martensite form, the metal can be easily modified into any shape. Alloy on heating, goes through transformation from Martensite to Austenite, after which they convert themselves back to Martensite as Austenite is not stable at room temperature and systems are more stable at lower temperatures. Memory transfer temperatures can be altered by slight changes in composition and by s…

Fermi Paradox

Astronomers says it could take about 1,500 years before earth could have a possible alien entry. This,they argue is because of the sheer size of the Milky way and the amount of time that it will take to receive our signals and respond. Patience is a virtue, they say. Whether you're waiting in a queue or waiting to finally talk with an alien. According to recent informations, Cornell astronomers say that, due to the sheer size of the Milky way, it will take a while [about 1,500 years] before earthlings can reasonably expect to hear back from any extraterrestrials who could've picked transmissions from earth. "We haven't heard from aliens yet, as space is a big place- but that doesn't mean no one is out there. It's possible to hear any time at all, but it becomes likely we will have heard around 1,500 years from now," says astronomy student Evan Solomonides from cornell University.
Solomonides is also the Co-author of a new study that analyzes what's k…

Bionic Leaf

From the science that we know, through this world that we show, using electricity, Scientists have figured out how to harness solar energy from photovoltaic cells to yield hydrogen that can be later used in fuel cells. Photosynthesis process involves solar energy converted into sugar molecules from air and water, that can feed the biotic component. Bionic leaves are artificial leaves that have mastered the art of this process using catalyst to make sunlight split water into hydrogen and oxygen, with a bacterium engineered to convert CO2 and Hydrogen into liquid fuel. Harvard University had assigned work on this particular project but latter results proved the fact that there was no practical usage of this Hydrogen produced. The findings are published Feb. 9 in PNAS. The co-first authors are Joseph Torella, a recent PhD graduate from the HMS Department of Systems Biology, and Christopher Gagliardi, a postdoctoral fellow in the Harvard Department of Chemistry and Chemical Biology. Pame…

A858

There are few prospects more enticing than the possibility that one has stumbled upon a genuine mystery, one that might be solved with a combination of diligence and brain power. It is the pivotal theme for legion of movies, books and TV shows especially the ones dealing with spies and detectives. The reddit community was introduced with such a mystery, a little over 5 years ago. A weird Subreddit known as ' r/A858DE45F56D9BC9 ' , which contains only strings of letters and numbers appeared on the site. To the casual eye, there wasn't much to see. The subreddit shared the same inscrutable set of numbers and letters as its moderator; the sidebar and comments provided no clarifying information. This particular mystery lacked its banal. Like one of many subreddits, which just confuses the user. But even then it seemed to serve some unknown private purpose. Its not perspicuous how the reddit community discovered A858's existence. Cryptic puzzles and group efforts to solve …
