So then what happens to light when it enters our eyes? It slows down and then what? Does it turn into mass? Are we light beings after all? The Physicist November 19, at 7: The lens and the fluid inside of our eyes allow light to pass through slightly slowed but when light hits the back of our eyes it gets absorbed just like it does when it hits a rock; nothing special.

Q: If light slows down in different materials, then how can it be a universal speed?

Development of tectonic theory Precursors The outlines of the continents flanking the Atlantic Ocean are so similar that their correspondence was apparent as soon as accurate maps became available. The earliest references to this similarity were made in by Flemish cartographer Abraham Ortelius and later in by the English philosopher Francis Bacon , in his book Novum Organum , and by French naturalist Georges-Louis Leclerc, count de Buffon , a century later.

Toward the end of the 18th century, Alexander von Humboldt , a German naturalist, suggested that the lands bordering the Atlantic Ocean had once been joined. In French geographer Antonio Snider-Pellegrini proposed that identical fossil plants in North American and European coal deposits could be explained if the two continents had formerly been connected. He suggested that the biblical Flood was due to the fragmentation of this continent , which was torn apart to restore the balance of a lopsided Earth.

The theory of relativity usually encompasses two interrelated theories by Albert Einstein: special relativity and general relativity. Special relativity applies to elementary particles and their interactions, describing all their physical phenomena except l relativity explains the law of gravitation and its relation to other forces of nature.

Is the pace of business really getting quicker? The firm sells 1, iPhones, iPads or Macs every couple of minutes. It whips through its inventories in four days and launches a new product every four weeks. Manic trading by computers and speculators means the average Apple share changes hands every five months. In a few years they can erode the profits of industries that took many decades to build.

Firms are born and die faster, it is widely claimed.

Speed of gravity

By Eric Betz December 8, Simonne The dead cores of two stars collided million years ago in a galaxy somewhat far away. The collision was so extreme that it caused a wrinkle in space-time — a gravitational wave. That gravitational wave and the light from the stellar explosion traveled together across the cosmos. They arrived at Earth simultaneously at 6:

Dec 08,  · The dead cores of two stars collided million years ago in a galaxy somewhat far away. The collision was so extreme that it caused a wrinkle in space-time — a gravitational wave.

He and his colleagues had conducted ethnographic studies on families and their children. Like many ethnographic studies — theirs uncovered many needs. Their main finding was that managing kids activities is stressful for dual-income families. Scott and his team were interested in how ubiquitous technologies in the home could help activity management for these families. He explained that they came up with countless concepts. How do you know which concept to make?

He continued that the common approach might be: Why not build it and see? There were several key reasons why this was not the best approach, namely: His team was uncomfortable deploying technologies at such an early stage in the development process. Unlike more established technology applications, ubiquitous computing does not have established design patterns to leverage.

So he explained that he looked in the design toolbox for some tools of the trade to help.

Has Doomsday Begun Already? But in the last decade, his work has been validated — often by his former critics — and scientists are now realizing that chaos and destruction are endemic in the universe [7]. When they examined the floors of these craters they noticed what looked like glazed donuts. These were actually chunks of moon dirt that were coated by glass. The glazed areas are clearly concentrated toward the top surfaces of protuberances, although they exist also on some sides.

Points and edges appear to be strongly favored for the glazing process.

Q: Why is the speed of light the fastest speed? Why is light so special?

Thomas Duff 25 January Catch phrase! For most, the scientific world is an amazing, but confusing place. Getting a glimpse into that world is something that many desire.

Albert Einstein published the theory of special relativity in , building on many theoretical results and empirical findings obtained by Albert A. Max Planck , Hermann Minkowski and others did subsequent work. Einstein developed general relativity between and , with contributions by many others after The final form of general relativity was published in Relativtheorie used in by Planck, who emphasized how the theory uses the principle of relativity.

In the discussion section of the same paper, Alfred Bucherer used for the first time the expression “theory of relativity” German: By comparison, general relativity did not appear to be as useful, beyond making minor corrections to predictions of Newtonian gravitation theory. Its mathematics of general relativity seemed difficult and fully understandable only by a small number of people.

Wikimedia Deutschland speed dating at Wikimania Usually advance registration is required for speed dating events. Men and women are rotated to meet each other over a series of short “dates” usually lasting from three to eight minutes depending on the organization running the event. At the end of each interval, the organizer rings a bell, clinks a glass, or blows a whistle to signal the participants to move on to the next date.

At the end of the event participants submit to the organizers a list of who they would like to provide their contact information to. If there is a match, contact information is forwarded to both parties. Contact information cannot be traded during the initial meeting, in order to reduce pressure to accept or reject a suitor to his or her face.

How to cycle faster and increase your average speed

If we can determine whether another person is a good match for us in just a minute or two, then speed dating is an optimal approach to selecting a mate. Why waste time on some jerk when you’ve already decided that you’ll most likely never speak to him again? Speed dating also offers a structure that — in its brevity — encourages polite behavior. And with the speed-dating service ringing a buzzer that signals the end of a couples’ time together, participants can relax knowing that they can largely avoid any awkward end-of-date moments.

But do the rules of attraction still apply in speed dating? University of Pennsylvania psychologists examined more than 10, client responses from Hurry Date’s database and found that in the context of a speed date, the usual rules of attraction go out the window.

Speed dating was a dating strategy born out of a need for busy professionals to optimize the time they spent well, dating. The theory goes that if you’re going to invest an hour of your life to romance, why meet just one person why not meet 2, 3, 4.

Important We believe any unbiased reader will realize that we were fair with our treatment of the two models in the table above. Yet, although the theory of evolution matches the facts in some cases, evolution is still an unproven theory. By now, you may believe it should be your first choice also. Unlike many others that preceded us, we attempted to find a clear defense of evolution for two reasons: To keep from being accused of bias. To keep from making claims that someone could refute later.

Even though there are a great number of claims in books and on the Internet, we could find no scientific, testable facts that support the theory of evolution. The best site we could find was at The University of California at Berkeley. If you are interested, click here to examine the scientific evidence recorded at UC Berkeley yourself. It includes lots of pictures, links to other pages, and scientific names. The site is very interesting and informative. Yet, we could not find a listing of the provable, testable facts supporting evolution anywhere.

Of course, you would require more than the energy in the whole known universe in order to attain c being massive. The only thing for certain is that the speed of light appears to be constant. In fact no one yet has been able to actually prove it. Einstein would have been better of saying he thinks the speed of light is the fastest thing in the universe. Phaedrus February 19, at 8: First of all, you have to understand, there is no such thing as an absolute speed. All motion is relative to something.
