The mirrors are controlled by a computer that follows the path of the sun, adjusting to the best angle to catch the rays and reflect them onto the town centre. Report by Sarah…

The mid-20th century was a bad time to be an apple lover. The produce section of supermarkets only had a few apples, and one stood tall above the rest: Mealy, and tough-skinned, it was the Red Delicious.
Back in those days, apples were a commodity, and the race to provide apples at the lowest price suppressed prices for all apple growers and discouraged apple innovation. A few things helped change that world for the better — and chief among them was the discovery of the Honeycrisp.

Ever wondered how a drone actually flies? Here I explain the simple physics of how a drone lifts off, hovers, turns and moves through the air. I also look briefly at how the remote controller communicates with the drone, how the battery powers the drone and how the GPS system works to keep the drone safe. I also mention some of the issues that can occur with drones and how to be careful not to crash them. This video teaches you how drones are able to fly and explains how they function at a…

In this tutorial, we’re going to show you how create an Excel 2016 Chart with Two Y Axes.
Once you have a chart and two sets of data plotted, left-click directly onto the line, columns, etc. of the set of data you want on the secondary axis. After selecting it, right-click it and choose Format Data Series.
Choose Secondary Axis instead of Primary Axis.
Optionally, to make things more visually appealing and differentiating the two axes, left-click one of them to select it. Under the Format…
