The main reasons given by people to explain why they hang their toilet paper a given way are ease of grabbing and habit.[11] Some particular advantages cited for each orientation include:

• Over reduces the risk of accidentally brushing the wall or cabinet with one's knuckles, potentially transferring grime and germs.[12]
• Over makes it easier to visually locate and to grasp the loose end.[13]
• Over gives hotels, cruise ships, office buildings, public places and homeowners with guest bathrooms the option to fold over the last sheet to show that the room has been cleaned.[14]
• Over is generally the intended direction of viewing for the manufacturer's branding, so patterned toilet paper looks better this way.[15]
• Under provides a tidier appearance, in that the loose end can be more hidden from view.[16][17]
• Under reduces the risk of a toddler or a house pet such as a cat unrolling the toilet paper when batting at the roll.[18]
• Under in a recreational vehicle may reduce unrolling during driving.[19] //

Advice columnist Ann Landers (Eppie Lederer) was once asked which way toilet paper should hang. She answered under, prompting thousands of letters in protest; she then recommended over, prompting thousands more.[47] She reflected that the 15,000 letters made toilet paper the most controversial issue in her column's 31-year history,[48] wondering, "With so many problems in the world, why were thousands of people making an issue of tissue?"[47]

In November 1986, Landers told the Canadian Commercial Travellers Association that "Fine-quality toilet paper has designs that are right side up" in the over position.[48] In 1996, she explained the issue on The Oprah Winfrey Show, where 68 percent of the studio audience favored over; Oprah suggested that under uses more paper.[49] In 1998, she wrote that the issue "seems destined to go on forever", insisting, "In spite of the fact that an overwhelming number of people prefer the roll hung so that the paper comes over the top, I still prefer to have the paper hanging close to the wall."[45] On the day of her last column in 2002, Landers wrote, "P.S. The toilet paper hangs over the top."[50]

If I pass a current through a copper conductor, how can I calculate how hot the conductor will get?

For example, if I have a 7.2kW load powered by 240VAC, the current will be 30A. If I transmit this power to the load via a 2.5mm2
copper conductor, how do I calculate how hot this conductor will get?

As a society, we seem to have mixed feelings about whether it's better to add or subtract things, advising both that "less is more" and "bigger is better." But these contradictory views play out across multibillion-dollar industries, with people salivating over the latest features of their hardware and software before bemoaning that the added complexities make the product difficult to use.

A team of researchers from the University of Virginia decided to look at the behavior underlying this tension, finding in a new paper that most people defaulted to assuming that the best way of handling a problem is to add new features. While it was easy to overcome this tendency with some simple nudges, the researchers suggest that this thought process may underlie some of the growing complexity of the modern world. //

The researchers say they got interested in the topic because they noticed that beyond the admonition that less is more, many fields had specific advice about improvement through subtraction. Editors caution writers about using excess language, social scientists talk about the need to remove barriers, and so on. In contrast, there are few reminders to add stuff to fix problems.

Perhaps, the researchers reasoned, people have no problems remembering to add things even without any prompting. //

Still, the study provides a simple and effective solution for getting a greater diversity of solutions—if it's appropriate, simply remind people that removing features is an option.

The first form calculates the pressure or friction loss along a given length of pipeline with a specified inside diameter. The second form calculates the minimum pipe size to limit pressure loss to a specified value.

Additional friction pressure losses occur due to fittings. These losses in-effect add extra additional length to the total pipeline. Use this calculator to estimate how much additional length needs to be added to the overall pipe length below in order to estimate these additional losses.

"The Big Burn Demonstration" shows that fire-treated cellulose insulation can provide over 50% more fire resistance than traditional fiberglass insulation. Sponsored by GreenFiber cellulose insulation. //

Three identical structures:

• No insulation -- collapsed at 40m
• Fiberglass insulated -- collapsed at 42m
• Cellulose insulated -- collapsed at 67m, 600F cooler than others just before they collapsed

There is a table of building material R-Values further down in this article, but first we should quickly cover some basics about R-Values, U-Factors, and calculating thermal resistance.

In construction, the R-value is the measurement of a material's capacity to resist heat flow from one side to the other. In simple terms, R-values measure the effectiveness of insulation and a higher number represents more effective insulation.

R-values are additive. For instance if you have a material with an R-value of 12 attached to another material with an R-value of 3, then both materials combined have an R-value of 15.

And the rise of UX writing“Writing is easy. All you have to do is cross out the wrong words.” — Mark Twain

Today, the anatomy of a digital experience includes images, shapes and words. These three are the equivalent of the 7 musical notes which can be combined in infinte number of permutations & combinations to craft a musical or digital experience. In the nascent stages of the UX industry, a UX designer was largely responsible for the ‘Shapes’ only. Shapes essentially relate to the navigation, interaction & layout elements of a digital interface such as tabs, cards, links, buttons, etc. Images and words were other people’s responsibility which was an extremely siloed and fragmented way of approaching UX design.

Experience is a seamless amalgamation of all three elements working together as a harmonious whole to create a desired feeling. As the UX industry matured, the UX designers role evolved as a result of this need for a more holistic approach to experience design.
Move over navigation…content is the new king.

Navigation used to be the most important pillar of UX design but it has gradually become less and less important. Navigation in the traditional sense means moving between screens. However, users today are not really moving between screens. Are they? Think about your content consumption behaviour on mobile phones… facebook for example…what percentage of using facebook involves ‘navigation’. You open the app and then basically just scroll. Mobile interfaces and the need to keep users hooked have ensured that infinite scrolls have replaced traditional navigation elements such as tabs, links, buttons, etc.

With Navigation out of the way, Content has emerged as the differentiator. If finding content is just as easy everywhere, what creates real digital differentiation today how the content is written.

What all does ‘content’ include on a digital interface…?

Below are a few examples/areas where words can play an important role...

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

The number of gasoline stations in the United States has been declining since 1994 when there were over 200,000 stations. From 2003 to 2006, those declines leveled off and in 2005, the number of stations increased slightly. However, since 2005, the number of stations has begun to decline again with a loss of more than 9,000 stations from 2010 to 2011.

As of 2016, there were approximately 111,100 such establishments across the United States.

Viton / FKM / FPM / Fluorosilicone

Viton is a trade name for a type of fluorocarbon rubber developed by DuPont specifically for the aerospace industry. The ASTM in the USA uses FKM as the generic term, but DIN/ISO in Europe and the rest of the world prefer FPM. It is often the most expensive of the three rubber types discussed here. FKM is compatible with petroleum fluids (including dino and synthetic lubricants, pure gasoline, and diesel). FKM is also fully compatible with water and ethylene glycol coolants. Most FKM grades are also a little better than NBR at handling biodiesel and ethanol-blended fuels, although FKM is still not the best choice for ethanol -- and it is a downright poor choice for nitromethane. Its high 400F operating temperature makes FKM a better choice for sealing engine, transmission, and differential oil systems.
