Nebia Low Flow High Pressure Shower Head

Shower Head Using Aerospace Technology Uses Less Water

June 10, 2016

Most people in the United States use about 90 gallons of water per day, with the largest uses of household-water occurring on the toilet and in the shower. Even though showers are one of the highest wasters of water, however, they are probably one of the personal experiences people would be willing to make the least compromise. The Nebia Company promises to not only improve your showering experience, but also help you use up to 70% less water!

After raising more than $2.6 million on the Kickstarter website, 15 days before the end of the campaign, the team is ready to start the manufacturing process, with the first showerheads expected to ship in the spring, possibly May or June 2016.

The six-person team behind Nebia Shower Head, which includes several thermal fluid experts, has spent the past several years doing research, solving equations, and building proto types in order to arrive with a new type of nozzle that, they say, brings the first technological innovation in the industry in more than half a century. Meanwhile, the company has attracted investments from Apple Corporation's Tim Cook as well as Eric Schmidt of Alphabet.

The results are quite impressive because on average, Americans take about eight minutes or so to shower, which results in using nearly 20 gallons of water on average. With the Nebia Low Flow High Pressure Shower Head, for the same amount of time, one will use up only six gallons, or 70 percent less water. With a starting price of nearly three hundred US dollars, the Nebia showerhead can pay for itself in a couple of years time.

High Flow Shower Head vs. Nebia Showerhead

The people who invented the Low Flow Nebia high pressure shower head say that it's easy to install.  Customers can simply unscrew their existing high flow shower head and screw on the Nebia showerhead with a wrench, some plumbers-tape, and some adhesive (included), without the need to break tiles or call the plumber. The low flo showerhead can slide up and down, pivot at an angle, and also includes a portable wand.

Win At Roulette System Physics Strategy

Scientists now say physics can be used to win at roulette

It helps to think like a physicist if you want to learn how to win at roulette.

They used a model of the motion of some roulette wheel and the ball, and based on physics principles and confirmed by experiments on an actual wheel itself, have revealed a couple of ways of beating the traditional odds against roulette system gamblers.

What they found is that the key to winning at roulette is knowing the precise location of the ball and the relative speeds of the ball and wheel when the roulette dealer — the casino who deals the game — spins the wheel and lets go of the roulette ball.

Once you know these starting conditions that allows you to overcome the traditional roulette wheel odds," says Michael Small, who is a statistician at the University of Western Australia. He did the study with Chi Kong Tse of Hong Kong Polytechnic University. "In some cases you can beat them quite significantly" he added.

A more simpler method the twp tested involved a careful observation and recording of the starting conditions by an individual or team of gamblers. In experiments on a roulette wheel in a lab, the roulette system method produced a predicted earning of about 20 percent instead of the traditional odds loss of exactly 2.7 percent for a European-style wheel. In U.S. casinos, the odds tilt further in the house's favor (5.25 percent)because the wheel contains one extra space.

Another way, with the use of a camera mounted above the wheel to obtain the same data, provided a much better prediction. Of course the question for roulette strategy players is how to not get caught by the casino security and how to hide this camera equipment from view.

Look for a slant in the roulette wheel
There was another idea that also helped the player to win at roulette even more.

"A very slight slant in the roulette table, could ... substantially enhance returns," they said.

"We extrapolate that prediction to the point where the ball hits one of the deflectors — the raised bumps in the wheel's rim that are added to increase the random bouncing of the ball," Small said. "Then we make a guess as to what portion of the wheel the ball is likely to land in."

The two scientists did their model on a standard casino roulette wheel installed in the lab.

"You basically press a button when the ball passes a certain point and then use that timing to make a prediction," Small explained.

History of the system physics of scientific roulette
The concept of using scientific understanding to beat the house is not new by any standard. In the late 1970s the "Eudaemons," a group of physics postgraduates, used theoretical insights and a rudimentary computer concealed in a shoe to win at roulette in Nevada in the 1970s. They did not reveal how things went.

Roulette Strategies for both sides
The study suggests gambling strategies for both sides of the roulette table.

"If you wish to beat the house, look for a wheel for which the ball drops only from one side of the rim — that is, a crooked table," Small explained this system. "Prediction becomes substantially simpler and more reliable."

However, Small also said that roulette "is a game of chance. Even if the odds are in your favor, there is still a probability of losing, and losing big. In the long run you would come out ahead but you may first need very deep pockets."

Here's the advice for the casino (house): "Train the croupiers to spin the ball when they release it, and make sure that the tables are level and the air conditioning is working," Small said, to allow for any influence of air resistance.

 
Here is a roulette strategy (its not the martingale roulette system) that is based upon on the scientific Fibonacci strategy with his own tweak to it. He's playing on Satoshibet. He says you are welcome to use this strategy. 
 

Scientists say we can avoid a mass extinction

Updated:
April 29, 2016

The latest research from Yale University urges scientists to move their focus from species extinction to species rarity in order to recognize, and avoid, a mass extinction in todays world.

Earth has experienced more than fourteen mass extinction events, when the great diversity of life on Earth disappeared and was replaced by a flora or fauna often entirely unlike what had come before. The largest of these events (the most recent, which wiped out the world's dinosaurs, was about 65 million years ago) have collectively become known as the “Five Mass World Extinctions.” In recent years, Hull says, some have argued that Earth is entering a sixth mass extinction event. It also was the topic of E. Kolbert’s Pulitzer Prize winning book, “The Sixth Extinction.” 

The scientists say, for example, that the modern ocean is full of ecological “ghosts", which are species that are now so rare that they no longer fill the ecological roles they once did, when they were more abundant. In other words, species rarity itself, rather than extinction, can lead to a cascade of changes within our ecosystems, much before the species goes extinct, the scientists explain.

“There are steps to take to avoid a mass extinction-like record, even if there are signs of it,” Hull stated. “This makes it all the more urgent to act early to protect ecosystems and restore once-abundant species.”

New research also suggests that extinctions during the time of humans are worse than we thought.
