Google doodles Dmitri Mendeleev's periodic table on the Russian chemist's 182nd birthday

The doodle on the Google home pages in many countries around the world shows Russian chemist Dmitri Mendeleev in the act of setting down the logic of his periodic table (which reportedly came to him in a dream).

Mendeleev had devised the periodic table - the comprehensive system for classifying the chemical elements.

Dmitri Mendeleev was born on February 8, 1834 in the far west of Russia's Siberia. He was the youngest of the many children of his parents.

According to Google's description of the doodle, in 1869, Dmitri Mendeleev made sense of the 56 elements known at the time, showing how they related to each other in a distinct pattern. His periodic table let elements fall into "periods" according to atomic mass and valence (the power that determines how they combine).

Scholars had attempted to organize the elements into a table before, but Mendeleev's work extended beyond mere chart-making. Mendeleev used the logic of his table to argue for the existence of yet-to-be discovered elements (like gallium and germanium), and even to predict their behaviours.

Some of these predictions were wrong, but the basic principles behind his periodic organisation continue to stand at the foundation of modern chemistry.

The periodic table of the elements (now with 118 elements and counting) adorns science classrooms worldwide.

Mendeleev died on February 2m 1907, aged 72, at Saint Petersburg, Russia.

The Dmitri Mendeleev Google doodle has been created by Google doodler Robinson Wood.

Virtual reality set to transform filmmaking

Chris Milk stepped onto a TED Conference stage and took the audience on an awe-inducing trip into the future of movies. While much of the early attention on virtual reality has focused on use of the immersive technology in video games, Milk and his US startup Vrse are using it to transform storytelling and filmgoing. "We have just started to scratch the surface of the true power of virtual reality," Milk said. "It's not a video game peripheral. It connects humans to other humans in a profound way... I think virtual reality has the potential to actually change the world." He had everyone in the Vancouver audience at TED , which ended Friday, hold Google Cardboard viewers to their eyes for what was billed as the world's collective virtual reality experience. Google Cardboard gear is literally that -- cardboard

Explained: Camera Improvements in the New HTC 10

With the HTC 10, the Taiwanese company is promising to undo the past wrongs in the cameras of its previous flagship phones. The camera has long a weak point in HTC devices. At first, HTC sacrificed image resolution in the M8 and made the size of individual pixels larger to capture more light (what HTC called Ultrapixel). But the resulting 4 megapixel images were often fuzzy, especially when cropped or enlarged. To fix the issue, in its next flagship - the M9 - HTC went with smaller individual pixels in a 20-megapixel camera last year, but it still underperformed in extreme situations, such as indoors and close-ups. In the HTC 10, the company attempts to strike a balance with larger individual pixels (1.55µm), but not as large as before and a 12 megapixel sensor in its camera coupled with a ƒ/1.8 lens. HTC accepts that in the imaging performance in the M9 was not up to the kind of spec of what they really like to see in a flagship. HTC is giving a slight boost to the selfi...

10 Smartphones with Features that You Won't Find in Any Other Phone

Here’s a list of phones which are first-of-their-kind. From feature phones to smartphones, flat screen to curved, fragile to shatterproof, mobile phones have evolved over the years. Although many industry analysts would like to call the current level of innovation reaching a stagnation point, there still are some manufacturers which have been able to surprise consumers by truly packing something different in their smartphones. We have compiled a list of phones which offer first-of-its-kind features, and they are not merely concepts. 1. Motorola X force - Shatterproof display Display today is the most vulnerable yet the most neglected element in modern smartphones. But Motorola finally paid heed to the fragile screen with the launch of the the Motorola X Force – the world’s first smartphone with a shatterproof display. The phone uses the Moto ShatterShield display technology, which is said to be an integrated system consisting of five layers designed from material...
