Lielais Kristaps - Big Christopher

Part 2. Riga Latvia. Galleria mall. Oldest Christmas Tree. Legend of Lielais Kristaps

While not the largest the Galleria mall is a nice place to drop around for groceries and a few extras. Seems that the first mention of any Christmas tree being decorated was that in Riga. Over 500 years a go, in 1510. Every city likes to have a founding legend and for Riga it's Big Christopher or for locals Lielais Kristaps

Quantum computing, the story of a wild idea: Andris Ambainis at TEDxRiga 2013

Andris is a computer scientist active in the fields of quantum information theory and quantum computing. His valuable scientific input into quantum computer theory makes him one of the world's leading scientists in this field. Andris has invented several of world's first algorithms for quantum computers, including a method to show that some computing problems are hard to solve even with a quantum computer. He is the first Latvian scientist to receive a grant for further research in quantum computing from the European Research Council -- an organisation that supports Europe's best scientists.

Quantum computers are a radically different approach to computing. They use quantum physics (physical laws that work on the level of individual atoms) to achieve faster computing or more secure data transmission. In this talk, Andris Ambainis describes what quantum computers will be able to do, how they work and why building a quantum computer has become one of central problems in physics.

In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
