Those who need to wrap an unusual shaped gift, such as a cylinder, can compare its radius with its height using the formula h/(p-2)***. The equation will help consumers decide whether they should roll the paper around the gift or wrap the paper over the top of it to ensure they reduce their gift-wrapping footprint.The formula has been created by Warwick Dumas from the Department of Mathematics, University of Leicester , who has been working with Bluewater to devise the perfect method of gift-wrapping that will help customers save time and money as well as reducing the amount of paper that will be wasted.
Where a>b>c are the dimensions of the item. Otherwise the best angle is such that the flaps only just meet.”
“For a cylinder, a rotational method of wrapping was compared with a method of wrapping where the cylinder is treated like a cuboid. It turns out that when the radius is greater than about 0.876 of the height (actually, h/(pi-2)), it is better to wrap the item as a cuboid but otherwise, better to roll it along the paper.”To help shoppers reduce their gift-wrapping footprint, Bluewater have launched a new gift-wrapping workshop which will provide a step-by-step practical guide on how to wrap items and save paper.

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
So-called quantum many-body scars allow quantum systems to stay out of equilibrium much longer, explaining experiment | Study published in Nature Physics
Recently, researchers from Harvard and MIT succeeded in trapping a record 53 atoms and individually controlling their quantum state, realizing what is called a...

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
