Throughout the animal kingdom, there is enormous diversity in the structure and faculty of eyesight.
Woodland Park Zoo hosts a wide variety of colored feathers, but just imagine if we could see these birds with ultraviolet vision! Figure 1: Intense attosecond optical pulses provide a potent tool for studying how light interacts with solids, liquids and gases. Pulses of light are very useful for probing the inner workings of atoms, molecules and solids. The light source is produced by firing two high-power infrared laser pulses of about 30 femtoseconds—just billionths of a microsecond—in duration into a chamber filled with xenon gas.
Takahashi's team demonstrated the utility of their light source by applying it to an analytical tool called pump–probe spectroscopy. The real strength of their novel light source, however, is the increase in peak pulse power. Ultrafast time-resolved laser spectroscopy is a technique that uses the interaction of light with matter to study the properties of physical systems. Electrons move extremely rapidly inside atoms and molecules (the order of magnitude is the attosecond, i.e. X-ray free-electron lasers (XFELs) produce higher-power laser pulses over a broader range of energies compared with most other x-ray sources. A team working at the SACLA X-ray Free-Electron Laser (XFEL) in Japan has succeeded in generating ultra-bright, two-color X-ray laser pulses, for the first time in the hard X-ray region. Applied scientists led by Caltech's Kerry Vahala have discovered a new type of optical soliton wave that travels in the wake of other soliton waves, hitching a ride on and feeding off of the energy of the other wave.
Scientists at the University of Rochester have taken a significant step forward in laser fusion research. Scientists at the High Energy Physics Group (HEP) of the University of the Witwatersrand in Johannesburg predict the existence of a new boson that might aid in the understanding of Dark Matter in the Universe.
When a river narrows or two rivers run into each other and merge, the water flow's speed increases and it becomes much stronger.
While it is heartwarming to see these trends in physics, it is still frustrating to observe how little progress has been made in physics in the past half-century along certain lines. Advertise hereUltraviolet rays (Actinic Rays)That portion of the electromagnetic spectrum immediately below the visible range and extending into the x-ray frequencies.
For each of the following calculate the total power radiated from the object and the wavelength at which it radiates most strongly.
The power figure is in excellent agreement with the actual value for the Sun (3.846 x 1026 W) and 502 nm is visible light, in the green region of the spectrum. The peak wavelength is in the infra red region of the spectrum but quite close to the red end of visible light.
5 Solar Energy Inventions for Everyday LifeFrom Tesla Motor's Powerwall to Michigan State's completely transparent solar cells, here's 5 solar energy inventions to make life greener! Solar Roadways: A Future of PossibilitySolar Roadways co-founders Julie and Scott Brusaw are changing the world around you - you just don't know it yet.
The Violation of Momentum: NASA's 'Impossible' EngineIs NASA's 'impossible' Cannae engine really defying conservation of momentum? To help the green movement fully take seed and replace outdated fossil fuel consumption, people must first be informed about their options. But how do you harness green power when the entire grid is still designed around traditional energy? For a company named after a man who believed in free, renewable energy for everyone, this new invention is changing the way we envision the emerging power grid of tomorrow. Considering the potential of both energy creation and storage at home, followed by the possible integration with equally inspired inventions like the ones below, a new picture of the energy grid begins to emerge. It works by utilizing a transparent luminescent solar concentrator (TLSC) which consists of organic salts that absorb non-visible wavelengths of ultraviolet and infrared light. Now imagine if these totally unobtrusive solar cells found their way into the new grid being built by Tesla and the inventors of Solar roadways? Created by Vincent Gerkens, the Blind Light (hence the name of Blight) captures light with flexible solar cells at day to create light with electroluminescent foil at night.
It’s no secret that many gripes about going green are often related to the aesthetic concerns. We all know that a new energy paradigm won’t arise from a single technology or breakthrough. Look at pressure differentials, spooky unknowns radiating from electromagnetism and other burgeoning technologies like the revolutionary Cannae Engine and a bigger picture emerges.
This is the ‘miracle’ engine that is seemingly defying conservation of momentum and creating thrust from electromagnetism radiation pressure differentials.
Before we fully understand this new technology, let’s review a few facts about current rocket technology to contrast the two. According the NASA, at liftoff an External Tank and orbiter carries a whopping 835,958 gallons of propellants including hydrogen, oxygen, monomethylhydrazine, nitrogen tetroxide and hydrazine.
Like the massive force exerted on a tiny bullet, the differential between fuel combustion and the relatively small weight of the craft ultimately helps it escape the Earth’s atmosphere.
When you also consider the horrors of the Challenger disaster, the idea of strapping a very big combustion engine beneath your seat to overcome incredible forces and escape the Earth’s gravitational pull quickly seems grossly outdated; especially in our imaginations and innovation centers of the brain. While the causes of the disaster were unrelated to the fuel itself, the combustible fuel always gets the final word in a space disaster. At the crux of the Cannae engine is this idea of creating energy without consuming a propellant. Here is where turning to the original source becomes imperative for reaching one’s own conclusions, or for at the very least, gaining a true sense for the actual observations gained at the experimental level.
It is certainly far too soon to say whether or not this new technology will be our saving grace in the future of space exploration. We can only hope that more scientists will have this kind of imagination and spend time looking in places that we haven’t looked before for renewable energy solutions.

Certain inventions are so revolutionary, they change the way we think and interact with the world. Enter Solar Roadways co-founders, Julie and Scott Brusaw – two modern visionaries reshaping our view of the future. The logic is so plainly stated in the prototypes, it is hard to picture a world where this incredible invention is not at the center of our increasingly interconnected web of renewable energy solutions.
Encased in a super-strong textured, tempered glass, each tile of the road contains solar cells overlaying a circuit board and microprocessor. Let’s pause for a moment and imagine the sprawling cocoon of urban heat islands checker-boarding the developed world being replaced by energy creating oases of solar cells. The microprocessor, for instance, serves as a two-way communications device, making it the perfect complement to driverless cars and other emerging technologies pioneered by Google. With 120 LEDs in each panel , and five different colors, an endless mosaic of possibility emerges for creating any light show, graphic or pattern you wish. With the ability to stay heated and prevent snow or frost build up, not only will winter driving be easier and safer, but driving in all seasons will be better lit, more responsive and able to integrate with advancements in safety and smart technology. We can look forward to customizable and awe inspiring designs to fit any utilitarian or aesthetic based need. Beneath these magnificent roads, a crawl space provides two sections: one for storm water and the other for power and data. For the storm water, Scott and Julie also see an opportunity for reducing pollution by whisking the runoff away to water treatment facilities, which can filter out toxins, runoff fertilizer and other water pollutants.
Harkening back to that pressure sensitive bit, there is also the added benefit of the preemptive detection of roadway obstructions. The prototype currently covers 69-percent of the road in the actual solar cells, but the final version will cover the full 100-percent. It is no accident that the names Tesla, Marconi and Edison made it into the same article as the Brusaw family’s incredible story, as their boldness to challenge the status quo is enough inspiration to keep any green dreamer running.
And, because SDO images are high-definition, researchers were able to zoom in on the flare to record its exquisite details.
The storm created spectacular aurorae and disrupted radio communications.The X-class flare was one of three solar flares emitted in a week week. One huge solar flare in 1972 cut off long-distance telephone communication in the mid-western state of Illinois, Nasa said. The views expressed in the contents above are those of our users and do not necessarily reflect the views of MailOnline. Oftentimes, we relate our own human eyesight to the visual capabilities of animals, but most evidence points to the contrary: in fact, humans might be an underdog in visual perception.
Eiji Takahashi and co?workers from the RIKEN Center for Advanced Photonics, in collaboration with the Center for Free-Electron Laser Science in Germany, have now created a table-top light source that can generate attosecond optical pulses without the complicated level of stabilization required by alternative approaches. The mixed infrared light, called a two-color waveform, interacts with the xenon atoms, temporarily releasing electrons.
In this powerful technique, a laser pulse—the pump—strikes an atom and excites its electrons.
The strength of the interaction between light and matter usually scales linearly with the power of the laser light.
Einstein proved mathematically a century ago that all things are various forms of energy, which is pure wave forms.
An important point here is that the colour of a luminous object is not the same as the colour of its peak wavelength. Fortunately for us the burst of UV is both very short lived and also heavily absorbed by the atmosphere. Because of this the molten metal will radiate large amounts of red, orange and yellow light.
Unlike with the near IR peak of the molten iron, the survivor gives out no visible radiation. We’re here to nurture the seed of the green movement and help it flourish through the free exchange of ideas. With the help of our community, we hope to provide do-it-yourself information on everything you need to live entirely off-the-grid and actually make money from the energy you give back. Whether you live in a mansion or a 500 Sq Ft studio, it’s a challenge of start up energy to change our time-tested ways. Essentially, if it uses glass in it’s design, one could image it could someday utilize this technology or a future variant of it. Storing energy in the blind’s upper housing, they are Venetian style for tilting at different angles to maximize exposure to the sun.
Imagine a day when all solar energy is old news and people are saying, “Can you believe they only invented this stuff 100 years ago?
Not only do solar shingles keep a lower profile than traditional standing solar panels, but they are becoming increasingly affordable.
Solar shingles can keep that low profile, and seamlessly integrate with your traditional cement shingle roof. And when the list of renewable energy solutions gets longer, that’s good news for everyone. So why not hold out hope that the technologies necessary to lay a strong foundation will find each other, and someday integrate into one pretty picture of sustainability. Weighing in at 1,607,185 pounds, the fuel eclipses the empty weight of a space shuttle itself (165,000 pounds according to Cool Cosmos) by roughly 90-percent.
Since space travel requires covering unimaginably long distances, the requisite fuel becomes a catch 22 of inefficiency, where the fuel needed to lift, well, the fuel, spirals into requiring ever-bigger spacecraft to maintain ever-longer distances.
Therefore, it’s deeply encouraged to read the NASA Technical Reports Server yourself: Anomalous Thrust Production from an RF Test Dvice Measured on a Low-Thrust Torsion Pendulum. Nonetheless, it is extremely exciting for anyone who is waiting and waiting for the end of the combustion engine and the fossil fuel burning paradigm. We just might have an effect on more than just space exploration with this type of thinking, as unforeseen technological applications for our everyday travel emerge.

From Edison’s incandescent light bulb to Tesla’s alternating current, Bell’s telephone and Marconi’s radio, the instant these proverbial monoliths hit the scene, life is never the same. Subject to rigorous load testing, traction testing and impact resistance testing, the tiles are pressure sensitive, heated, and packed with LED lights. Think of the energy savings, reduction of emissions and water conservation that accompanies cooler temperatures (as pointed out by the EPA), and then multiply that across the globe. In short, the solar roads have the added ‘sexiness’ of twinkling like a school of iridescent fish in the far reaches of our imaginations.
From ball courts and dance floors, to easily rearranged parking lots and roadways, literally any pattern conceivable can be programmed into the roads to serve our needs.
Everything from fiber optic, cable and telephone lines can be run beneath the road and easily serviced, simultaneously removing wires from exposure to the elements and making the need for unsightly overhead cables a bad memory.
In short, imagine integrated smart road-to-car communication where a fallen boulder or the weight of an elk or moose can trigger sensors that alert your car to an upcoming obstruction. We need solar roadways to usher in the future energy paradigm, which anyone who can step outside of themselves knows is surely coming. When the electrons return to their host atoms, they produce an isolated extreme-ultraviolet (XUV) pulse (Fig. The pulses of XUV light created by Takahashi and his team should open the door to investigating more complex effects in the nonlinear regime. String theory has addressed this to an extent, yet the mental constructs involved in its nomenclature can lead to considerable confusion.
The Sun emits all visible wavelengths and the combination produces an overall yellow tinted white light. Because of the bias towards the blue end of the visible spectrum, lightning (and all electrical sparks) appear blue white. In many conditions the molten metal surface will be so bright that it will be perceived as being almost white.
The IR radiation that they do give out however can be used to search for them if an IR sensitive camera is available. Come here for regular updates on experimental green technology, news on solar energy, wind energy, geothermal energy, weird science news, and do-it-yourself renewable energy ideas collated from the web. Yet thanks to emerging technologies, there are baby steps you may be missing in this transition that could make things easier. But more importantly, it’s a power storage system that makes solar energy less fleeting than in the past.
Certain solar technologies are becoming everyday objects, which is certainly the path to full adoption for any technology. As Scientific American pointed out in 2013, advances in photovoltaic technology have led to ever cheaper solar shingles that can now compete with traditional bolt-on solar panels. For anyone with a little imagination, combustion engines have the look of an extinct technology, and one we are likely to shake our heads at in 100 years like a bad haircut in our ‘80s yearbook.
Let’s unpack this a bit and try to get a sense for what makes it tick – and if it actually can revolutionize space travel to bring us into the great beyond. Arguably, what can be demonstrated in space certainly might find a place in terrestrial transportation, making this exciting news for a myriad of reasons. Again, just another benefit to add to the long list of improvements readily available in this brave new world.
A full time-dependent picture of the atom and its electron's reaction to the high-power laser light can then be constructed by varying the delay between the pump and probe pulses. This experiment proves further that atoms are nothing more than a conglomeration of wave forms, which emanate in perfect harmonic geometric intervals from the nucleus, which is an eddy current (aka vortex) in the very fabric of what we primitively call space-time, produced by a parallax or junction of multiple harmonically compatible wave forms in some higher dimension, which is a perfect harmonic of the sum-total of what manifests into what we call the external universe.All is energy, learn the principles governing wave forms to unlock the mysteries!
However lightning is so bright (especially if seen at night) that it is often interpreted as being an intense, pure white. The same technology can also be used by fire fighters looking for unconscious victims in a smoke filled room and police chasing a criminal at night.
In so much, as one might imagine, half of the web is saying it’s a scam while the other half is reporting it as fact. The resultant pulses last just 500 attoseconds, some 60 times shorter than the input pulses.
The attosecond light pulses created by Takahashi and his team increase the temporal resolution of pump–probe spectroscopy to a level that enables researchers to gain a deeper understanding of ultrafast processes, such as ionization. Incidentally the strong UV emissions from electrical discharges are the reason why eye protection needs to be worn during arc welding. Furthermore, the central wavelength of the pulse is 40 nanometers and its peak energy is 1.3 millijoules—more than a hundred times greater than the energy achieved by previous approaches. Turns out electroluminescent foil doesn’t run quite as cheap of that roll of tinfoil in your kitchen drawer. The bigger problem then is a lack of perceptible light - at least if you can't see in the UV. Being able to do so, you'd be fine though, as the highly scattered light that does fall onto the earth is disproportionately blue and UV.
Because light tends to move through non-vacuum media at different speeds (think prism), it is bent and thus focused differentially by a lens.
Since not all of the light can be brought to an acceptable focus at once, some wavelengths of light are not good for acute vision in a typical single chambered eye. Having a mutlifocal lens is one way around this, so that light of differnt colors is focused at different lateral points along the retina, but unfocused light causes a kind of light pollution that has to be dealt with.
Another solution is to have a tiered retina, where light of different wavelengths is focused at different distances away from the lens.
This works well for a large enough eye (like we have), but the capacity to form a tiered retina has to be available to whatever lineage.
