World Changing Solar Power Innovations

“Every hour the sun beams onto Earth more than enough energy to satisfy global energy needs for an entire year.” – National Geographic.com

“The sun is a mass of incandescent gas, a gigantic nuclear furnace.” – They Might Be Giants

In a world where energy resources are finite, we only need to look skyward to find an unlimited source of power. The sun, which already does a darn good job in keeping us warm and illuminated, and also prevents us from spinning off screaming into the black void of space, can also change the way we use energy. Here are a handful of solar power innovations that are making an impact on our planet right now, or are on the verge of a breakthrough.

Solar power: the world energy game-changer

Solar Leaves
Taking a page from Mother Nature, researchers have developed an artificial leaf that’s made from a thin silicon solar cell that separates oxygen and hydrogen molecules and powers fuel cells that in turn create electricity. Their effectiveness is not as good as solar panels, but this is offset by their profoundly inexpensive production costs.

Mobile Devices
There are over one billion smart phones worldwide, and every single one of them is thirsty for electricity. Mind boggling, isn’t it? Portable charging stations powered by solar energy and mobile device covers that are effective solar panels, are starting to make their presences known.

BIPVs
The acronym stands for Building Integrated Photovoltaics. In layman’s terms, they are solar panels built into the construction of a building, as opposed to adding panels later on. With BIPVs, you can have facades, curtain walls, or roof shingles, all with thin-film solar panels built right into them. They are cost-effective, and when you get right down to it, look pretty awesome.

Solar-Powered Vehicles
Nothing drives home (pun intended) the need for solar powered innovation like pulling your car up to the gas pump and watching your bank account get pumped into the gas tank. Significant strides have been made in bringing the production costs of a solar-powered electric car down to the same level as conventional automobile manufacturing. Also on the horizon are new developments in solar fuel charging stations that could really come in handy when the sun’s not out there, shining.

Solar-Charging Appliances
Places in the world that aren’t connected to a power grid usually have to rely on things like kerosene lamps, which present their own hazards and pollution. Companies are now producing inexpensive, long-lasting solar charging appliances, which includes lamps. In addition, clean energy microgrids, which provide power to up to 100 households.

Infrared Solar Power
If you remember your science classes, you know that sunlight exists not only on the normal light wavelengths, but also in the ultra-violet and infrared spectrums as well. As it stands right now, we can only collect visible light and turn it into energy. This accounts for three-fifths of the sun’s light. Imagine what we can do if we can harness the rest of it as well! Researchers at MIT have developed carbon-based solar panels (as opposed to the usual silicon-based ones) that can grab infrared light.

Unfortunately, there are still many details to work out, so we won’t be seeing this innovation rolled out anytime soon.

With these innovations and others, the world’s energy consumption should look very different in the next quarter century. Unlimited energy from the sun means a brighter future for everyone.

2x3D lets viewers watch 2D or 3D movies on the same screen

“This system has several applications. One that’s easy to understand is multilingual viewing. For example, I’m giving this presentation in Japanese, but the pictures themselves could be in English. What’s important is that everyone looks at the same screen, and the information delivered is different for people who are wearing the glasses and people who aren’t.”


“Regarding the hardware, there are two ordinary projectors used concurrently, almost the same as a 3D set-up. If you project two pictures, usually, you see both pictures, like this. If you pass them through a filter, you can see one picture. As for the other picture, we want to make it like this. Firstly, to cancel the other picture, we superpose, say, a blue picture on the orange parts, to make them white. Then, we combine the canceled parts with the pictures we want to add, and ultimately, we achieve this kind of hidden picture. I said we simply use complementary colors, but it can’t be done that simply. That’s where the technology comes in.”

“Superposing pictures leads to lower contrast. The contrast is halved, and that’s the weak point here. But compared with the shutter method, the picture quality isn’t reduced, nor is the resolution. Regarding color, current cinema projectors support 12-bit, so progress is fast. You can use deep color, or quality can be improved, right away, by using more projectors. So, I think that’s a promising method.”

Rehabilitation support robot “R-cloud”

Associate Professor Toshiaki Tsuji’s Laboratory at Saitama University has developed R-cloud, a rehabilitation support robot that enables users to view how their own muscles move during rehabilitation and training.

“This rehabilitation support robot is used for strengthening the arms. Its moving parts use pneumatic muscles, and it provides support with gentle movements so it is very safe. Another distinguishing feature is haptic signal processing, a technique that estimates muscular force during training and makes this information visible. It also has a feature that quantifies and evaluates the effect of training. ”

“This robot has a force sensor and a sensor to measure the arm angle. Based on data collected from these sensors, calculations are made on the force of muscle contraction within the arm, as well as on the amount of calories consumed by each muscle during training. So the robot is equipped with technology that quantifies the degree of effectiveness of training. In addition, we use augmented reality technology to make these results visible. ”

AR support system for constructing tensegrity structures

This is an AR support system for constructing objects with a tensegrity structure, created by the Hirasawa Lab at Chiba University. “We liked this shape a lot. But things like this are difficult to design and build. So, we’re using AR to support their construction.” “This structure consists of three-rod units. Here, we’re using AR to help fabricate the units correctly.” “As you can see, the ends of these rods have red target marks on them. The marks are there to show whether the top is in the right position. I think you can see that this one is misaligned, but if we line it up, a different part gets out of alignment. In ways like this, tensegrity units involve a delicate balance of wire tensions. So, it’s difficult to adjust their positions overall. If you pull this, then these match, but this one goes too far. It’s really hard to adjust them while measuring them in the same way. So, the method we suggest is to build the structure while checking that the overall concept is correct, using AR to help.”

Display complex congenital heart conditions By 3D modeling system

Researchers have developed a system that can show in 3D the complicated heart structures of babies with congenital heart conditions. The pictures are easy to understand, and can be rendered quickly.

“Babies can’t be put in 3D scanners like MRI or CT at first. So, we use echo imaging. Echo images have low quality, which makes it hard to produce 3D pictures from them automatically. So, a specialist physician does some of the work manually, while looking at the echo images, and uses a template 3D model. The template is gradually changed into a model of the baby. The concept here is that, by repeating this kind of process, a picture can be produced in about 5 minutes.”

“Of course, a specialist can imagine a 3D picture just by looking at an echo image. But until now, there wasn’t any way for specialists to show their conceptions to other people. The problem was, physicians couldn’t tell other healthcare staff, or the baby’s parents, what image they had in their head. But using this system, specialists can quickly show other people what they’re thinking.”

Scientists Claim Breakthrough Skin Cancer Cure

Cancer is the term for a group of more than 100 diseases. Cancer begins when the cell’s genetic material is damaged, leading to mutations that affect normal progress of the cell’s life cycle. Normal cells multiply in required number according to the need of the organs, mature, and die. Cancer cells are different – they keep multiplying and form a tumor for lack of space, and invade other tissues, which normal cells do not do. Cancer cells travel to other parts of the body too, and this is called metastasis.

 

The National Cancer Institute has divided cancer into five categories:

 

  1. Carcinoma: Caner that begins in the skin or linings of organs

  2. Sarcoma: cancer that begins in bones, cartilage, fat, muscle, blood vessels, or connective tissue

  3. Leukemia: cancer that begins in blood forming tissue

  4. Lymphoma and Myeloma: cancer that begins in the cells of immune system

  5. Central nervous system cancers: these are cancers that begin in tissues of the brain and the spinal cord.

 

 

 

Treatment of Cancer over the years

 

Although the treatment of cancer has undergone tremendous progress due to significant understanding of the biological processes that lead to cancer, there are still many areas of cancer development that need to be comprehended.

 

As new information is revealed everyday, new medicinesand strategies are also being developed to modify the existing therapies.

 

 

 

New Miracle Drug For Skin Cancer

 

One such ground breaking research was reported in September about drugs to treat skin cancer and by extension treat other type as well.

 

Melanoma is one of the most aggressive cancers with a poor prognosis, and a high death rate, with patients dying within months of diagnosis. Less than 25% of those diagnosed survive for 12 months. The number of cases of melanoma is increasing with more and more people going for holidays in sunny climates.

 

Professor Peter Johnson, Chief Clinician, Cancer Research UK, is a leading expert in lymphoma, and is involved in developing new treatments for body’s immune system to attack tumors.

 

A report of research done under the leadership of Professor Johnson was published on 29th September in Daily Mail.

 

According to the report, Professor Johnson, and his team of researchers have found new combination of drugs to attack tumors, using the body’s natural defenses.

 

Combination Drugs: IPI and PD1

 

This new treatment involves combination of two drugs ipilimumab (ipi) and anti-PD1s, which breaks down cancer cell defenses. This combination of drugs can effectively “reboot” a patient’s immune system.

 

The treatment of using this combination of drugs is still in clinical trial, but the results which are available are quite promising.

 

The team of scientists at the Cancer Research UK hails the findings as amazing for skin cancer.

 

The research was presented at the European Cancer Congress Conference held at Amsterdam, during the last weekend of September,  it was declared that one in six melanoma patients treated with this miraculous drug was already cured. According to Dr.Alexander Eggermont, from France, “if this success rate continues, there is a possibility to cure more than half of advanced skin cancer sufferers, who normally die after a few months of being diagnosed with melanoma skin cancer, in the next 5 to 10 years”. He further said that this bizarre prediction would have made the people laugh if made 5 years ago.

 

The Daily Express correspondent Ricky Senly reported that the scientists were amazed at the results and were using the word “cure” for the first time in context with cancer. The doctors are hoping to use the drug on other kinds of cancers too. Researchers described the results of the same drug’s trials on kidney and lung cancer patients as “very exciting”.

 

Dr James Larkin, of the Royal Marsden Hospital said that the drug is really big news, because the skin cancer melanoma has spread to other parts of the body, it is considered incurable and patients die within months. Therefore if the patient treated with ipi, is still alive, after 3 years, then it is likely that he is clinically cured.

 

His work on the combination of ipi with PD1 is showing spectacular results.

 

The ipi drug with a brand name of Yervoy will be soon available for mainstream usage, if and when the manufacturers reduce its price.

Floating interactive display could be used in ATMs of the future

The Aerial Imaging (AI) Plate, developed by Asukanet, is a next-generation display device which can form an image which appears to be floating in midair from light that passes through it.

“At first sight, our AI Plate just looks like a sheet of glass. But in fact, it’s an optical device, designed to reflect light twice. An ordinary mirror just reflects things, but the AI Plate forms an image from light passing through the plate, at the same distance beyond the plate as the object is from the plate. Unfortunately, with a 2D camera, the floating object doesn’t actually appear to be floating, so it looks as if it’s just stuck to the glass.”

“Of course, one way of using this plate is digital signage, to show advertisements in the air. But our next development theme will be finding applications if the plate is made interactive, by combining it with sensors. For example, if an image of sushi is floating in the air, and you order some, the plate could become a point of sale device and take your order. The biggest feature of the plate is that if you switch it off, you get a flat table with nothing on it. So you can then eat your food right there, for example.”

Asukanet is also developing new technology, as an evolution of the AI Plate.

Next generation IGZO MEMS display

Microscopic MEMS shutters which opens and close are used to control the output of light from the red, green, blue and white LEDs which make up each pixel. By using this system, the display features high levels of brightness and color reproduction in any environment, and significantly lowers power consumption.

“When when compared to existing LCD sections, the colour filtration along with polarizing menu usually are not utilized, therefore there isn’t a light-weight attenuation plus the light-weight can be used effectively. The particular light-weight through the backlight reaches your people eye straight with substantial colour chastity along with lighting. inch

JPL, Masten Testing New Precision Landing Software

A year after NASA’s Mars rover Curiosity’s landed on Mars, engineers at NASA’s Jet Propulsion Laboratory in Pasadena, Calif., are testing a sophisticated flight-control algorithm that could allow for even more precise, pinpoint landings of future Martian spacecraf


Flight testing of the new Fuel Optimal Large Divert Guidance algorithm — G-FOLD for short — for planetary pinpoint landing is being conducted jointly by JPL engineers in cooperation with Masten Space Systems in Mojave, Calif., using Masten’s XA-0.1B “Xombie” vertical-launch, vertical-landing experimental rocket.

NASA’s house Technology Mission board of directors is facilitating the tests via its Game-Changing Development and Flight Opportunities Programs; the latter managed at NASA’s John Dryden Flight centre at Edwards Air Force Base, Calif. the 2 house technology programs work along to check game-changing technologies by taking advantage of Flight Opportunities’ commercially provided suborbital platforms and flights.

“The Flight Opportunities Program supports each the event of innovative house technology and therefore the rising suborbital trade by victimization business suborbital vehicles to check ideas that would any mankind’s exploration and understanding of the universe,” aforesaid Saint Christopher Baker, a campaign manager for the program. “The collaboration between JPL and Masten to check G-FOLD could be a nice example of however we tend to hope to any the exploration of the scheme whereas increase the economic base required to advance future house endeavors.”

These algorithms don’t optimize fuel usage and considerably limit however so much the craft may be amused throughout descent. The new G-FOLD rule fabricated by JPL autonomously generates fuel-optimal landing trajectories in real time and provides a key new technology needed for planetary pinpoint landing. Pinpoint landing capability can enable robotic missions to access presently inaccessible science targets. For crewed missions, it’ll enable inflated preciseness with stripped fuel needs to modify landing larger payloads in shut proximity to preset targets.

Quantum Algorithm Could Improve Stealth Fighter Design

Researchers at the Johns Hopkins University Applied Physics Laboratory have devised a quantum algorithm for solving big linear systems of equations. Furthermore, they say the algorithm could be used to calculate complex measurements such as radar cross sections, an ability integral to the development of radar stealth technology, among many other applications.

The field of quantum computing is still relatively young. First proposed in the 1980s, a quantum computer harnesses the principles of quantum mechanics (the physics of very small things like electrons and photons) to process information significantly faster than traditional computers. A classical computer has a memory made up of bits (units of information), where each bit represents either a one or a zero. A quantum computer maintains a sequence of qubits. Similar to a bit, a single qubit can represent a one or a zero, but it can also represent any quantum superposition of these two states, meaning it can be both a one and a zero simultaneously.

While several few-qubit systems have been built, a full-scale quantum computer is still years away. Qubits are difficult to manipulate, since any disturbance causes them to fall out of their quantum state or “decohere,” and their behavior can no longer be explained by quantum mechanics. Other larger scale non-universal computers have been built — including the much-heralded D-Wave computer, purchased by NASA and Google last month — but none of them currently have the power to replace classical computers.

Theoretical breakthroughs in quantum algorithm design are few and far between. In 1994 Peter Shor introduced a method for finding the prime factors of large numbers — a capability that would render modern cryptography vulnerable. Fifteen years later, MIT researchers presented the Quantum Linear Systems Algorithm (QLSA), that promised to bring the same type of efficiency to systems of linear equations — whose solution is crucial to image processing, video processing, signal processing, robot control, weather modeling, genetic analysis and population analysis, to name just a few applications.

“But it didn’t quite deliver; based on their process, no one could figure out how to get a useful answer out of the computer,” explains APL’s David Clader, who along with Bryan Jacobs, and Chad Sprouse wrote, “Preconditioned Quantum Linear System Algorithm.”

As presented, the algorithm had three features that made it difficult to apply to generic problem specifications and achieve the promised exponential speedup, they wrote. Technical details with setting up the problem on a quantum computer made it unclear how one would apply it to a real-world calculation. In addition, the promise of exponential speedup was only true for a very restricted set of linear systems that typically don’t exist in real-world problems. Finally, getting a useful answer from the calculation proved to be quite difficult due to intricacies with the inherently probabilistic nature of quantum measurement.

In their paper, the authors describe however they were able to solve every of those problems and extract helpful info from the answer. what is more, they incontestable  the relevance of the algorithmic program by showing the way to code the matter of scheming the magnetic attraction scattering crosswise, additionally referred to as measuring instrument cross section (RCS).

RCS measurements became progressively vital to the military. It refers to the facility that may be came back by Associate in Nursing object once lit with measuring instrument. the facility indicates however well the microwave radarion and ranging|radiolocation|measuring instrument|measuring system|measuring device} will detect or track that focus on, thus there ar current efforts to cut back the RCS of such objects as missiles, ships, tanks and craft. With a quantum pc, APL researchers have currently shown that these calculations will be done a lot of quicker and model rather more complicated objects than would be potential victimization even on the foremost powerful classical supercomputers.

The work was funded by the Intelligence Advanced analysis comes Activity beneath its Quantum applied science program, that explores queries regarding the procedure resources needed to run quantum algorithms on realistic quantum computers.

Graphene Nanoscrolls Are Formed by Decoration of Magnetic Nanoparticles

Researchers at Umeå University, together with researchers at Uppsala University and Stockholm University, show in a new study how nitrogen doped graphene can be rolled into perfect Archimedean nano scrolls by adhering magnetic iron oxide nanoparticles on the surface of the graphene sheets. The new material may have very good properties for application as electrodes in for example Li-ion batteries.

Graphene is one of the most interesting materials for future applications in everything from high performance electronics, optical components to flexible and strong materials. Ordinary graphene consists of carbon sheets that are single or few atomic layers thick.

In the study the researchers have modified the graphene by replacing some of the carbon atoms by nitrogen atoms. By this method they obtain anchoring sites for the iron oxide nanoparticles that are decorated onto the graphene sheets in a solution process. In the decoration process one can control the type of iron oxide nanoparticles that are formed on the graphene surface, so that they either form so called hematite (the reddish form of iron oxide that often is found in nature) or maghemite, a less stable and more magnetic form of iron oxide.

“Interestingly we observed that when the graphene is decorated by maghemite, the graphene sheets spontaneously start to roll into perfect Archimedean nano scrolls, while when decorated by the less magnetic hematite nanoparticles the graphene remain as open sheets, says Thomas Wågberg, Senior lecturer at the Department of Physics at Umeå University.

The nanoscrolls can be visualized as traditional “Swiss rolls” where the sponge-cake represents the graphene, and the creamy filling is the iron oxide nanoparticles. The graphene nanoscrolls are however around one million times thinner.

The results that now have been published in Nature Communications are conceptually interesting for several reasons. It shows that the magnetic interaction between the iron oxide nanoparticles is one of the main effects behind the scroll formation. It also shows that the nitrogen defects in the graphene lattice are necessary for both stabilizing a sufficiently high number of maghemite nanoparticles, and also responsible for “buckling” the graphene sheets and thereby lowering the formation energy of the nanoscrolls.

The process is extraordinary efficient. Almost 100 percent of the graphene sheets are scrolled. After the decoration with maghemite particles the research team could not find any open graphene sheets.

Moreover, they showed that by removing the iron oxide nanoparticles by acid treatment the nanoscrolls again open up and go back to single graphene sheets

“Besides adding valuable fundamental understanding in the physics and chemistry of graphene, nitrogen-doping and nanoparticles we have reasons to believe that the iron oxide decorated nitrogen doped graphene nanoscrolls have very good properties for application as electrodes in for example Li-ion batteries, one of the most important batteries in daily life electronics, “ says Thomas Wågberg.

IBIS pneumatic keyhole surgery robot

“A feature of the slave robot is, it’s powered entirely by air. Nearly all conventional robots are electrically powered, but by driving this robot pneumatically, we’ve made it possible to gently absorb the force when the robot touches something. The force on the tip of the robot is estimated from the air pressure data, and that information is sent to the surgeon’s master robot. So, it can be fed back to the surgeon’s hand. Alternatively, a large force can be produced by a very lightweight, compact unit. An advantage of this phy4system is, the robot overall can be made extremely compact.”

 

“Here, the user is operating the master robot. This demonstration enables you to experience, for example, how you can feel the reaction force when you pull the rubber band.”

“Of course, you can eliminate shaking of the hand, change the motion ratio, and change the force feedback factor. So, depending on the medical staff and the situation, the parameters can be varied, to make the system easier to use on the spot.”

This camera system will track in no time moving objects, keeping them within the center of the screen the least bit times. presently below development by the Ishikawa Oku laboratory. at the University of Yeddo, this latest version captures Full HD video and may be used outdoors.

“Ordinarily, to alter the direction a camera faces, you progress the camera automatically. however during this system, it isn’t the camera that moves, it is the mirrors. This makes it doable to alter wherever you are looking extremely quickly. during this demonstration, we’re following a table game ball. The ball moves very quick, however this method will keep compensating for the ball’s motion, therefore the ball stays within the middle of the image.”

“Using a rotating mirror could be a common technique, however sometimes, the mirror is ahead of the camera, thus a awfully giant mirror is required. however a feature of this method is, it will even capture optical lens pictures with atiny low mirror. that is as a result of the system contains special optics known as a pupil shift system.”

“Another vital purpose is, this method will in no time image process to acknowledge the topic. It captures and processes a picture each 1/1000th of a second. during this approach, it will track the topic stably and ceaselessly, just by feeding back the subject’s position, while not notably predicting its behavior.”

“For example, this method will record, in nice detail, the moment a player hits a home run, as well as however the bat bends and also the ball reacts, and also the ball’s ensuant path. Or in association football, it will record things like penalty kicks in wonderful detail. we expect this may create it doable to shoot sports during a extremely compelling approach.”

Privacy visor glasses jam facial recognition systems

Photos taken without people’s knowledge can violate privacy. For example, photos may be posted online, along with metadata including the time and location. But by wearing this device, you can stop your privacy from being infringed in such ways.

“You can try wearing sunglasses. But sunglasses alone can’t prevent face detection. Because face detection uses features like the eyes and nose, it’s hard to prevent just by concealing your eyes. This is the privacy visor I have developed, which uses 11 near-infrared LEDs. I’m switching it on now. It prevents face detection, like this.”

“Light from these near-infrared LEDs can’t be seen by the human eye, but when it passes through a camera’s imaging device, it appears bright. The LEDs are installed in these locations because, a feature of face detection is, the eyes and part of the nose appear dark, while another part of the nose appears bright. So, by placing light sources mostly near dark parts of the face, we’ve succeeded in canceling face detection characteristics, making face detection fail.”

Tofu handling robot picks up soft, delicate food with ease

“First, the golem checks that means the curd is facing, and the way huge it’s, employing a camera. the photographs ar analyzed by a laptop, and therefore the golem works out that thanks to orient the curd. Once it picks the curd up, it then puts it in a very package. A feature of this golem is that the hand, which might gently carry terribly soft, fragile things while not damaging them. This hand uses a special surface process, that was developed by our company.”

“If curd is carried quickly, it breaks. So, the golem moves curd quite slowly, shifting only one,200 to 1,500 items per hour. however firmer things, like deep-fried curd, will be carried at a rate of two,500 per hour.”

“We ar victimisation chiefly firm curd in our demonstration however it also can handle soft curd. We’ve conjointly enclosed some soft curd here, therefore this technique will even handle delicate things like that.”

“We’ve barely developed this technique. folks have asked regarding victimisation it for food, eggs, and meat, and that we suppose it may be used for all types of foods. The golem itself may be a terribly general model. So, for instance, if we tend to scale back production volume on one line, we tend to may use the golem on another line, simply by ever-changing its program. that is the neatest thing regarding victimisation robots.”

A) (3E8 m/s) / (4.28E-7 m) = 7.009E14 Hz CORRECT
B) (7.009E14 Hz) * (6.6262E-34 J/s) = 4.644E-19 J CORRECT
This is where I need Help
C) What is the momentum of the photon?
[(7.009E14 Hz)*(6.6262E-34 J/s)] / (3E8 m/s) = 1.546E-27

I think I have the number but I can’t submit it to check it, until I have the right unit of measurement. I tried (Hz*m/s), (m/s), (nm*m/s).
If I don’t have the number right would you let me know as well.

Conservation of Momentum

1. The problem statement, all variables and given/known data
Box A of mass 1.20 kg is sliding to the right across a frictionless table at a speed of 2.52 m/s. Box A collides with Box B which has a mass of 2.56 kg, and Box A bounces straight back to the left with a speed of 0.665 m/s.
A) What is the momentum of Box A before the collision?
3.02 kg*m/s To the Right Correct Answer

B) What is the momentum of Box A after the collision?

0.798 kg*m/s Correct: To the Left Correct Answer

C) What is the momentum of Box B after the collision? This is the one I need help with!

2. Relevant equations
Momentum(P)=mass(kg)*Velocity(kg*m/s)
Momentum(P-before)=Momentum(P-after)

3. The attempt at a solution
A) P=m*V=(1.20 kg)(2.52 m/s)=3.02 kg*m/s To the right CORRECT
B) P=m*V=(1.20 kg)(.665 m/s)=.798 kg*m/s To the Left CORRECT
This is the part I am having trouble with
C) Momentum(before)=Momentum(after); P=m*V
PBeforeA+PBeforeB=PAfterA+PAfterB
[(1.20 kg)(2.52 m/s)]+[(2.56 kg)(0 m/s)] = [(1.20 kg)(.665 m/s)]+[]
[3.02 kg*m/s]+[0 kg*m/s] = [.798 kg*m/s]+[PAfterB]
[(3.02 kg*m/s)/(.798 kg*m/s)] = PAfterB
PAfterB = [(3.02 kg*m/s)/(.798 kg*m/s)]
PAfterB = 3.78 kg*m/s : To the Right

The answer is incorrect. I am assuming the [To the right] portion is correct because BoxA and BoxB collided; this means that they are asserting equal and opposite force on each other and because BoxA went to the Left, BoxB must go to the Right.

This leaves the incorrect portion to be the Momentum of BoxB after the collision. I double checked my math, a numerous amount of time, so I don’t know where I am going wrong.

Help is appreciated!

Normalizing a wave function and finding probability density

1. The problem statement, all variables and given/known data

A state of a particle bounded by infinite potential walls at x=0 and x=L is described by a wave function [itex]\psi = 1\phi_1 + 2\phi_2 [/itex] where [itex]\phi_i[/itex] are the stationary states.
a) Normalize the wave function.
b) What is the probability to find the particle between x=L/4 and x=3L/4?
c) Calculate the expectation value of the Hamiltonian operator [itex]\langle \hat{H} \rangle[/itex]

2. Relevant equations

I wasn’t sure Schrödinger’s equation was necessary here: [itex]i \hbar \frac{\partial \psi}{\partial t} = – \frac{\hbar^2}{2m}\frac{\partial^2 \psi}{\partial x^2} + V(x)\psi(x,t)[/itex]
but I did remember that the solution to any wavefunction — at least the stationary state — is going to be [itex]\psi(x) = A sin(\frac{n\pi x}{a})[/itex] where a is the length of your "box" for the particle. So in this case a=L.

3. The attempt at a solution

We have a situation where V(x) = 0 0 < x < L and V(x) = infinity outside of that. So the V(x) term for inside the well disappears (it’s zero).

The probability of the particle being at any point from 0 to L is 1. So I need to integrate the wave functions squared over that interval. By the superposition principle it is OK to just add them.

[itex]\psi = 1\phi_1 + 2\phi_2 [/itex]
[itex]\psi = (1\phi_1 + 2\phi_2)(1\phi_1^* + 2\phi_2^*)[/itex]

multiply this out
[itex]\psi = (1\phi_1^* \phi_1 + 2\phi_1 \phi_2^* + 2\phi_1^* \phi_2 + 4\phi_2^*\phi_2)[/itex]

SInce the phi functions are eigenvalues, the ones on the diagonal of the matrix are the only ones not zero. So we get
[itex]\psi = (1\phi_1^* \phi_1 + 4\phi_2^*\phi_2) = (1 + 4) [/itex]

because the complex conjugate of a function multiplied by a function is 1.

That makes the whole thing add up to five. and since the probability of finding the particle on the interval 0 to x is

[tex]\int^L_0 |\psi|^2 dx = 1 \rightarrow \int^L_0 |5|^2 dx = 1 \rightarrow 25x = 1[/tex]

so x = 1/5 for the whole interval, (since that is the square root of 1/25) so normalizing the wave function I should get

[itex]\psi = \frac{1}{5}\phi_1 + \frac{2}{5}\phi_2 [/itex]

and for the probability that the particle is at L/4 and 3/4 L

(25L/4) and (75L/4)

Now, if someone could tell me where I am getting lot and doing this completely wrong :-)

Actually I know this is wrong, because the probabilities should add up to one, at least with the stationary states.

After that I get even more confused. I think — and I stress think — I have some vague idea of how to get expectation values, but whenever someone mentions stuff like "Hamiltonian operator" I want to run away and hide. :-) More seriously, I am trying to grasp what exactly is meant by the notation [itex]\langle \hat{H} \rangle[/itex] – some of it is a notational question, but i get confused because I am never sure if they want the Hamiltonian like what you do in mechanics or something else. I feel like if someone could explain that I’d be a lot further along.

thanks in advance.

PS I put this up before in advanced HW, but perhaps it goes here. (Nobody answered, I might have put up the wrong tags) The line between what counts as advanced around here and what is basic seems rather fluid :-) But since I am clearly the dumbest guy in the class I’ll start here. :-)

Quantum Computing? Progress in the fight against quantum dissipation

Scientists have confirmed a 50-year-old, previously untested theoretical prediction in physics and improved the energy storage time of a quantum switch by several orders of magnitude. High-quality quantum switches are essential for the development of quantum computers and the quantum internet — innovations that would offer vastly greater information processing power and speed than classical (digital) computers, as well as more secure information transmission.

Searching for dark energy with neutrons: With neutrons, scientists can now look for dark energy in the lab

It does not always take a huge accelerator to do particle physics: First results from a low energy, table top alternative takes validity of Newtonian gravity down by five orders of magnitude and narrows the potential properties of the forces and particles that may exist beyond it by more than one hundred thousand times. Gravity resonance spectroscopy is so sensitive that it can now be used to search for Dark Matter and Dark Energy.

Scientists capture ultrafast snapshots of light-driven superconductivity

A new study pins down a major factor behind the appearance of superconductivity — the ability to conduct electricity with 100 percent efficiency — in a promising copper-oxide material. Scientists used carefully timed pairs of laser pulses to trigger superconductivity in the material and immediately take x-ray snapshots of its atomic and electronic structure as superconductivity emerged.

Radiocarbon Dating

1. The problem statement, all variables and given/known data
The practical limit to ages that can be determined by radiocarbon dating is about 41000-yr-old sample, what percentage of the original 6 12 C atoms remains?

2. Relevant equations
(N1/No)=e^-λt

3. The attempt at a solution
Variables:
t = 41,000 yrs
T1/2 of Carbon = 5730 yrs
ln2 = .693

I basically plugged in the numbers and solved because you are given all the variables.

(N1/No)=e^-λt
(N1/No) = e^-(ln2/T1/2)t
(N1/No) = e^-(.693/5730 yrs)(41,000 yrs)
ln(N1/No) = -(.693/5730 yrs)(41,000 yrs)
ln(N1/No) = -(1.2094E-4)(41,000 yrs)
ln(N1/No) = -4.95863
(N1/No) = e^(-4.95863)
(N1/No) = .0102548

I then calculated for the % because the answer .012548 is a fraction.

.0102548/100 %
=1.025%

However that answer is incorrect and I’m not exactly sure why. I made sure that I was using the (ln)-function instead of the (log)-function. I don’t know if it is my math or if I’m putting it into the website incorrectly.

Any help would be greatly appreciated!

Normal Force

1. The problem statement, all variables and given/known data
A 1300 kg car is travelling at 25 m/s as it passes the crest of a hill that has a radius of curvature of 120m. Determine the normal force acting on the car at the crest of the hill.

2. Relevant equations

3. The attempt at a solution
I know that for horizontal surfaces the Normal Force is equal and opposite to the force of gravity. So I figured out the force of gravity (mg) but am unsure if this is right because I am not sure if this is a horizontal surface in the question. The question does mention the crest of a hill so do I treat this like a vertical circular motion question?
