To explain what makes quantum computers so different from their classical counterparts we begin by having a closer look at a basic chunk of information namely one bit. A bit is the basic unit of information in a digital computer. From a physical point of view, a bit is a physical system which can be prepared in one of the two different states representing two logical values --- no or yes, false or true, or simply 0 or 1. For example, in digital computers, the voltage between the plates in a capacitor represents a bit of information: a charged c ....etc

Imagine a computer whose memory is exponentially larger than its apparent physical size; a computer that can manipulate an exponential set of inputs simultaneously; a computer that computes in the twilight zone of Hilbert space. You would be thinking of a quantum computer. Relatively few and simple concepts from quantum mechanics are needed to make quantum computers a possibility. The subtlety has been in learning to manipulate these concepts. Is such a computer an inevitability or will it is too difficult to build?

The subject of quantum co ....etc

Quantum Wells, Quantum Wire, and Quantum Dots




I'd like to explore the material known as Wellstone. There are some interesting aspects to this material, and it is written about in Hacking Matter by Will McCarthy. It is not necessarily nanotechnology, so much as it is quantum level materials and bio-molecular control over nano sized or meso-sized particles.
We will return to the world of Nanotechnology and DNA computing shortly, for now - let's talk about Wellstone.

ASSESSMENT OF IMPACTS, ADAPTATION, AND VULNERABILITY
TO CLIMATE CHANGE IN EGYPT


Introduction

The inhabited area in Egypt does not exceed 3.5% of the total area and is confined to the narrow strip which boarders the main course of the River Nile from Aswan in the south to Cairo in the north plus the Nile Delta which covers the area from Cairo to the shore line of the Mediterranean Sea between the cities of Damietta in the east and Rosetta in the west.
The main agricultural regions in Egypt are; Nile Delta ....etc

Egypt's military-led government faced a major challenge after two days of clashes between Muslims and Christians in which state media reported 12 people died and 238 were injured.
Egypt's worst sectarian strife since 13 people died on March 9 when a church was burned was triggered by rumors Christians had abducted a woman who converted to Islam.
The army said that 190 people would be tried in military courts over the violence that erupted on Saturday.
On Sunday, hundreds of ....etc

quantum computers exploit quantum effects to compute in ways that are faster or more efficient than, or even impossible, on conventional computers. Quantum computers use a specific physical implementation to gain a computational advantage over conventional computers. Properties called superposition and entanglement may, in some cases, allow an exponential amount of parallelism. Also, special purpose machines like quantum cryptographic devices use entanglement and other peculiarities like quantum uncertainty. ....etc

Abstract


To speak the name of the dead is to make him live again
Ancient Egypt civilization lasted over 3000 years.

Egyptian monuments have been around so long
that their monuments were ancient even in Greek
and Roman times…. but one key question has
always loomed: how were the pyramids built?

The Pyramids are one of the Seven Wonders of the Ancient World. Decorating the Nile waterfront they loom over passing boats. They are the lasting reminders of the Pharaohs that once ruled Egypt ....etc
