Who Invented Facebook?

When and why was Facebook invented? And more importantly, who invented Facebook? Well, Mark Elliot Zuckerberg was one of the inventors of Facebook, and although he’s the original inventor, Aaron Greenspan, his Harvard University mate claims otherwise. Read on to know more about the guy behind Facebook.

Facebook is one of the most popular websites that offers social networking today with more than 1 billion users around the world. Online social networking is just like like-minded people coming together for some activities, forming groups, having discussions, sharing photographs, etc. Similarly, Facebook enables all these activities by various applications, for example, providing forums, photo sharing options, video uploading, keeping a track on all the happenings in their formed communities, people they have approved to be linked to, etc. Online gaming is one of the biggest USPs of Facebook, and indeed, games like Farmville and Mafia Wars have…

Lawrencium Facts

Lawrencium is an element and is written as Lr as of now (legal from 1997). Prior to this, it was denoted by Lw. One of the very interesting facts about Lawrencium is that it is an element which does not exist naturally and that it is also one in the list of radioactive elements. The following are some of the very interesting facts about the element.

Electron Configuration

Electron configuration in Lawrencium is [Rn] 5f14 7s2 7p1 with the atomic number 103 (2, 8, 18, 32, 32, 9, 2). The bracketed numbers show the distribution of electrons in each orbital shell of the lawrencium atom. This chemical element is placed in the actinides section of the periodic table. The atomic mass of lawrencium is 262 and has a half-life of 3.6 hours.

Physical Properties

  1. Though there is not any distinctive in the appearance of lawrencium, it is silvery white or grayish in…

Spectrophotometer Uses

Biology, physics, chemistry, microbiology, medicine, forensics, and textile industries are some areas where a spectrophotometer can be used.

What is Spectrophotometry?

We can get an idea of what this is by looking at its name carefully; ‘spectro’ means band of colors, ‘photo’ means light, and ‘meter’ is a device for measuring something. Thus, as the name suggests, a spectrophotometer is a measuring device, which compares properties of two kinds of light i.e., the wavelength.

Initially, the main utility of a spectrophotometer came into play, for the inability of the naked eye to mark the differences. There are umpteen number of compounds, and remembering and detecting the extinction coefficients are practically impossible.

Spectrophotometer comes in varied shapes and sizes. It looks like a bar code reader, fax machine, or a weighing scale, etc., depending on its size. It can be hand-held or kept on a table just like a printer…

Researchers pluck carbon from the sky, turn it into diamonds


from Engadget Full RSS Feed


Carbon’s the perfect material to build strong yet lightweight materials, but it’s also the reason we’re running head-first into an ecological apocalypse. Wouldn’t it be great if we could snatch the excess CO2 from the air and use it to cheaply build aircraft fuselages, modern cars and artificial diamonds? That’s what a group of researchers from George Washington University claim to have achieved at a recent meeting of the American Chemical Society. Not only would it mean that future engineering projects would have an abundant source of cheap materials, but it also has planet-saving consequences.

The process works a little like the electrolysis you’d have seen in high school. Rather than dunking a pair of electrodes in a bath of water, however, they’re placed in a mix of molten lithium carbonate and lithium oxide. When this compound reacts, it effectively pulls in…
