CS GO Widescreen FOV Settings

See more stretched FOV footage here: https://youtu.be/FiFdVKRxQYk Want to know what CS:GO is like at different aspect ratios? Want to get more viewing angles AND better FPS? I talk you through a few ways in this video. starting with an easy but offline method and then an online one with pros and cons. 0:22 - FOV with console command. Here's something to get you started on an offline server: sv_cheats 1;fov_cs_debug 120 1:21 - Ultra wide-screen in proper matches. Once again, here's a value to get you started. Use these launch options: -w 1920 -h 540 -windowed OR, (thanks to Pandaclaw), type this in the console in-game: mat_setvideomode 1920 540 1 2:09 - Change your weapon model's FOV using this video: https://youtu.be/qM8EVhPML6w Download CRU here: http://www.monitortests.com/forum/thread-custom-resolution-utility-cru QUESTION: 'You say wider FOV makes FPS lower, but then say it makes it higher!!! How?' Because the amount lost by being wider is outweighed by the smaller resolution. Resolution is the major factor that determines the speed that CS:GO runs at, so having the game run as a slit across the screen instead of fullscreen helps the framerate considerably. I suspect that a lot of people use blackbars because higher FPS helps them, instead they could use the blackbars along the top and bottom of their screen and get the best of both worlds.

B-29 HIGH ALTITUDE BOMBING RAID OVER JAPAN   TARGET INVISIBLE  25994
 
08:36
Made in 1945 just after WWII ended, TARGET INVISIBLE was produced by the First Motion Picture Unit and features actor Clayton Moore (best known as 'The Lone Ranger') at the end speaking about war bonds. The film follows a squadron of bombers from their base in the Marianas through their mission over Tokyo. Particular emphasis is given on the use of radar for guidance to the target. At this time radar was fairly new and prized as one of the Allies' high tech weapons, and the film explains how it was instrumental in winning the war. At the end of the short, an announcer tells the audience that, while the war is over, Americans can now help win the peace sponsoring science through buying bonds. Radar is an object-detection system that uses radio waves to determine the range, angle, or velocity of objects. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar transmits radio waves or microwaves that reflect from any object in their path. A receive radar, which is typically the same system as the transmit radar, receives and processes these reflected waves to determine properties of the object(s). Radar was secretly developed by several nations in the period before and during World War II. The term RADAR was coined in 1940 by the United States Navy as an acronym for RAdio Detection And Ranging. The term radar has since entered English and other languages as a common noun, losing all capitalization.

Slew to Radar
 
00:19
Radars are fantastic geospatial sensors and nowadays, they are actually quite affordable for general perimeter surveillance. However, radars lack the ability to give a visual identification to allow the operator to determine if this is a good guy or a bad guy. However, if you combine the radar with a geo-referenced PTZ camera a good portion of this can be done automatically. Just like the fence & camera example, the radar hands off the target information to the geospatial VMS, its presented as bearing & range, but is easily converted to latitude & longitude. It can even provide speed for fast moving targets, allowing the camera to automatically center the object in its field of view for ID. The radar can then continue to provide the camera location information for repointing, as show in this video. You can see each time the camera re-centers after it is given new data from the radar.

Distances: Crash Course Astronomy #25
 
11:21
How do astronomers make sense out of the vastness of space? How do they study things so far away? Today Phil talks about distances, going back to early astronomy. Ancient Greeks were able to find the size of the Earth, and from that the distance to and the sizes of the Moon and Sun. Once the Earth/Sun distance was found, parallax was used to find the distance to nearby stars, and that was bootstrapped using brightness to determine the distances to much farther stars. -- Table of Contents Ancient Greeks Finding the Size of the Earth 1:07 Earth/Sun Distance Began Our Use of Parallax 5:39 Brightness Relation to Distance 9:07 -- PBS Digital Studios: http://youtube.com/pbsdigitalstudios Follow Phil on Twitter: https://twitter.com/badastronomer Want to find Crash Course elsewhere on the internet?

DARPA's Space Surveillance Telescope: What It Does
 
04:30
Current deep space telescopes do not provide a comprehensive picture of all objects in orbit around the Earth. Existing search telescopes have relatively narrow fields of view and cannot reliably detect and track faint objects, including small objects in geosynchronous orbits (roughly 22,000 miles high). There may be as many as hundreds of thousands of additional pieces of debris and asteroids that are too faint to track with current sensors. The Space Surveillance Telescope program aims to enable ground-based, broad-area search, detection, and tracking of faint objects in deep space for purposes such as space mission assurance and asteroid detection. SST offers improvements in determining the orbits of newly discovered objects and provides rapid observations of events that may only occur over a relatively short period of time, like a supernova.

If you want to try this experiment, instructions are here: link.springer.com/article/10.1007/s12650-016-0383-5 The standard theory of quantum mechanics leaves a bit to be desired. As Richard Feynman put it, "I think I can safely say that no one understands quantum mechanics." This is because observations of experiments have led us to a theory that contradicts common sense. The wave function contains all the information that is knowable about a particle, yet it can only be used to calculate probabilities of where a particle will likely turn up. It can't give us an actual account of where the particle went or where it will be at some later time. Some have suggested that this theory is incomplete. Maybe something is going on beneath the radar of standard quantum theory and somehow producing the appearance of randomness and uncertainty without actually being random or uncertain. Theories of this sort are called hidden variable theories because they propose entities that aren't observable. One such theory is pilot wave theory, first proposed by de Broglie, but later developed by Bohm. The idea here is that a particle oscillates, creating a wave. It then interacts with the wave and this complex interaction determines its motion. Experiments using silicone oil droplets on a vibrating bath provide a remarkable physical realization of pilot wave theories. They give us a physical picture of what the quantum world might look like if this is what's going on - and this theory is still deterministic. The particle is never in two places at once and there is no randomness. Edited by Robert Dahlem Sound design by A Shell in the Pit

http://www.facebook.com/ScienceReason ... [email protected] (Episode 4): Following The Redshift (Part 1) - The Earliest Stars and Galaxies In The Universe. From HST (Hubble Space Telescope) to JWST (James Webb Space Telescope). In this fourth episode of the [email protected] vodcast series Rebecca Barnes will identify some of the key discoveries achieved with the famous Hubble Space Telescope, look at the concept of redshift, and meet a new telescope that will be used to uncover the early Universe. --- Please SUBSCRIBE to Science & Reason: • http://www.youtube.com/Best0fScience • http://www.youtube.com/ScienceTV • http://www.youtube.com/FFreeThinker --- 'Redshift' is a key concept for astronomers. The term can be understood literally - the wavelength of the light is stretched, so the light is seen as 'shifted' towards the red part of the spectrum. Something similar happens to sound waves when a source of sound moves relative to an observer. This effect is called the 'Doppler effect' after Christian Andreas Doppler, an Austrian mathematician who discovered that the frequency of sound waves changes if the source of sound and the observer are moving relative to each other. If the two are approaching, then the frequency heard by the observer is higher; if they move away from each other, the frequency heard is lower. There are many everyday examples of the Doppler effect - the changing pitch of police and ambulance sirens, or train whistles and racing car engines as they pass by. In every case, there is an audible change in pitch as the source approaches and then passes an observer. Everyone has heard the increased pitch of an approaching police siren and the sharp decrease in pitch as the siren passes by and recedes. The effect arises because the sound waves arrive at the listener's ear closer together as the source approaches, and further apart as it recedes. Light behaves like a wave, so light from a luminous object undergoes a Doppler-like shift if the source is moving relative to us. Ever since 1929, when Edwin Hubble discovered that the Universe is expanding, we have known that most other galaxies are moving away from us. Light from these galaxies is shifted to longer (and this means redder) wavelengths - in other words, it is 'red-shifted'. Since light travels at such a great speed relative to everyday phenomena (a million times faster than sound) we do not experience this red shift in our daily lives. The red shift of a distant galaxy or quasar is easily measured by comparing its spectrum with a reference laboratory spectrum. Atomic emission and absorption lines occur at well-known wavelengths. By measuring the location of these lines in astronomical spectra, astronomers can determine the red shift of the receding sources. However, to be accurate, the red shifts observed in distant objects are not exactly due to the Doppler phenomenon, but are rather a result of the expansion of the Universe. Doppler shifts arise from the relative motion of source and observer through space, whereas astronomical redshifts are 'expansion redshifts' due to the expansion of space itself. Two objects can actually be stationary in space and still experience a red shift if the intervening space itself is expanding. A convenient analogy for the expansion of the Universe is a loaf of unbaked raisin bread. The raisins are at rest relative to one another in the dough before it is placed in the oven. As the bread rises, it also expands, making the space between the raisins increase. If the raisins could see, they would observe that all the other raisins were moving away from them although they themselves were stationary within the loaf. Only the dough - their 'Universe' - is expanding. • http://www.esa.int/esaSC/SEM8AAR1VED_index_0.html .

Turning 2D into depth images
 
02:42
Most cameras just record colour but now the 3D shapes of objects, captured through only a single lens, can be accurately estimated using new software developed by UCL computer scientists. The method, published at CVPR 2017, gives state-of-the-art results and works with existing photos, allowing any camera to map the depth for every pixel it captures. The technology has a wide variety of applications, from augmented reality in computer games and apps, to robot interaction, and self-driving cars. Historical images and videos can also be analysed by the software, which is useful for reconstruction of incidents or to automatically convert 2D films into immersive 3D. Inferring object-range from a simple image by using real-time software has a whole host of potential uses. Depth mapping is critical for self-driving cars to avoid collisions, for example. Currently, car manufacturers use a combination of laser-scanners and/or radar sensors, which have limitations. They all use cameras too, but the individual cameras couldn’t provide meaningful depth information. The new software was developed using machine learning methods and has been trained and tested in outdoor and urban environments. It successfully estimates depths for thin structures such as street signs and poles, as well as people and cars, and quickly predicts a dense depth map for each 512 x 256 pixel image, running at over 25 frames per second. Currently, depth mapping systems rely on bulky binocular stereo rigs or a single camera paired with a laser or light-pattern projector that don’t work well outdoors because objects move too fast and sunlight dwarfs the projected patterns. There are other machine-learning based systems also seeking to get depth from single photographs, but those are trained in different ways, with some needing elusive high-quality depth information. The new technology doesn’t need real-life depth datasets, and outperforms all the other systems. Once trained, it runs in the field by processing one normal single-lens photo after another. Understanding the shape of a scene from a single image is a fundamental problem. A 360 degree depth map would be fantastically useful – it could drive wearable tech to assist disabled people with navigation, or to map real-life locations for virtual reality gaming, for example. At the moment, the software requires a desktop computer to process individual images, but they plan on miniaturising it, so it can be run on hand-held devices such as phones and tablets, making it more accessible to app developers. It has also optimised only for outdoor use, so the next step is to train it on indoor environments. The team has patented the technology for commercial use through UCL Business, but has made the code free for academic use. Funding for the research was kindly provided by the Engineering and Physical Sciences Research Council.

MAPPING YOUR SURROUNDINGS WITH MATLAB & ARDUINO
 
06:37
Collisions with the walls and other cars while parking or unparking the car or while reversing the car is a very common problem that we all face in our everyday life. The situation becomes worse with crowd. Not only this , people also get engaged in arguments and conflicts disrupting social peace and harmony. To rectify the above problem, we have made a system that will map your surrounding showing the position of obstacles and will also give an idea of the size of the obstacle. In this project, we are using an ultrasonic Distance sensor. It generates sound waves beyond the scope of human hearing and measures distance by calculating the time required by these waves to hit an obstacle and travel back. This is similar to the principle used by bats. Another component that we are going to use is a servo motor. It differs from the usual DC motor in that it can turn very precisely to a given angular position and hold its state there. When a servo motor is given pulses of a specific duration, it moves to the corresponding angular position. We will be using both these components to get a 180° field of view. After the system gets the reading from the surrounding using the sensor and the motor , it will create a polar plot or map of the surrounding showing the position of different objects in the field of view of our system .

G3T Ground Penetrating Radar
 
01:05
Here are some of the applications of Ground Penetrating Radar GPR can determine accurate depth and location of rebar, post tension cables, electrical conduit or plastic lines with in or beneath the concrete slab. GPR can locate piles, beams and other thickness changes in your foundation or slab. GPR can pin point voids or soil disturbances such as buried trenches below the slab. GPR can be used to accurately locate in floor heating lines eliminating costly strikes. GPR is not harmful or destructive and only requires being on one side of the slab. It utilizes high frequency light waves to produce a 3D view in real time of objects or voids within or under a surface. PCD or "Power Cable Detection" mode can be used to see current flow. This function is extremely useful when locating electrical conduit in a busy area.

MEGA UFOs BY THE SUN: Strange Objects in SOHO Images.(A Must Watch).
 
03:46
The LASCO coronagraphs are very sensitive to dust particles that pass through the field of view. This is similar to the effect of a sunbeam shining through a window and scattering from the minute dust particles suspended in the air. Similarly, very small particles, at small angles from the Sun, get illuminated by the bright sun and are easily seen. Usually the space environment is very clean, but sometimes a streak is observed. Even more rare are images with multiple streaks, indicating more than one particle. The width of the streaks vary because the particles are at varying distances from the instrument. Since the instrument is focused for infinity the particles appear out of focus and thus broad. This can be used to determine how far away the particle is, assuming that the particle is otherwise very small. The length of the streak depends upon how fast the particle is moving, and how far it is from the instrument. For a given speed, the closer the particle is, the longer the track. Where do the particles come from? Some of them are obviously from the spacecraft. For example, the image on Jan 14, 1998 shows tracks that seem to emanate from a point. We believe that something must have hit the spacecraft and we see a shower of particles from the impact. But most of the images just show one or possibly 2 tracks. We believe that these are the interplanetary dust particles. Some images show particle tracks with different directions or radiants.

Ultrasound Doppler Radar
 
50:23
Current depth sensors (LIDARs, Kinect, stereo cameras, etc.) are expensive, power hungry and often demand dedicated hardware, cooling systems and precise calibration. On top of this, further processing needs to be done to get a velocity profile of the objects being sensed. In this work, we have developed an Ultrasound-Doppler Radar to investigate the application of Doppler Effect and Time-of-Flight to simultaneously estimate the speed and location of targets in a 360 degree horizontal field of view around a circular array of ultrasound piezoelectric transducers. The array consists of 8 pairs of ultrasound loudspeakers and receivers. To improve the spatial angular resolution and the framerate of our sensing, we employ offline loudspeaker and microphone beamforming. The time-delay and Doppler stretch factors (indicating the position and velocity respectively) are estimated together each frame. The device is low form-factor, inexpensive, low power consuming and enables a variety of interesting applications for indoor and outdoor, stationary and mobile Robotics sensing and Human-Computer-Interaction.

Matplotlib star chart
 
00:56
https://github.com/ussserrr/starmap-northern-animation Star map of the northern hemisphere made with Python packages for astronomy: astropy, ephem, pyorbital. It uses matplotlib to render the graphics. Constellations (more accurately, asterisms) and their stars to plot are determined by a user and defined as Python dictionary object. Then, the dedicated script automatically download necessary data (stars coordinates) (SIMBAD database). The main program puts all constellations forms on the plot and draws over the main plane the field of view: the circle showing the region that observer can see at this time in this geolocation. So, 2 coordinate systems are present: bigger outer circle corresponds to RA-dec (ICRS, equatorial coordinate system, J2000.0 equinox (default for astropy)) and smaller inner circle goes with alt-az (horizontal coordinate system). Additionally, Sun, Moon, Solar system planets and ISS are placed on the plot (if currently located under the northern hemisphere sky). The small circle is a projection of the field-of-view (FOV) on the big ICRS circle and that's the cause why its form is not an ideal circle and why the altitude axis is curved. Only if an observation location is the North Pole point the FOV will have a round shape and also centers of two circles will fit each other. The more you move away from the North Pole the bigger a distortion of the FOV circle and constellations. The straight line is the celestial meridian. The intersection of two lines is a current zenith. Note that around the horizon line sky objects are less observable due to the thicker atmosphere and the diffractions phenomena. The app can be used for educational purposes and planning of astronomical observations.

MCPTAM Indoor Quadrotor Flight With Small Rotation, Overlapping vs. Non-overlapping FOV Clusters
 
01:05
The Multi-Camera Parallel Tracking and Mapping (MCPTAM) algorithm 3D pose estimates using both overlapping and non-overlapping field-of-view (FOV) multicamera clusters mounted on a quadrotor unmanned aerial vehicle (UAV) in an indoor laboratory environment and compared against Vicon indoor positioning system (IPS) as ground truth. There is no rotation in the quadrotor motion and as a result, the non-overlapping camera cluster is unable to accurately recover the scale of the environment and motion. The target environment map is generated from scratch using the first set of camera images. As the quadrotor moves about the environment, the orientation estimates are accurate from the start, and the position estimates improve as the scale is determined over time. The 4 cameras are rigidly-mounted on the quadrotor: camera1 -- looks left camera2 -- looks right camera3 -- looks back and down camera4 -- looks forward For the non-overlapping cluster, only camera1, camera2, and the lower triangle portion for the images from camera3 are used and as a result, each part of the environment is viewed by only one camera at any point in time. This work is the result of collaboration between Adam Harmat and Dr. Inna Sharf from McGill University, Montreal QC, Canada, and Michael Tribou, Dr. Steven Waslander, and Dr. David Wang from the University of Waterloo, Waterloo ON, Canada.

Atmospheric Long Distance Range Finder or Passive Optical Radar
 
05:50
I will describe here an optical system that is an extension of the dual optical system described before and that will allow the distance/speed calculation to objects relatively far away, in the order of 100s of kilometers. This kind of system have a direct application to long distance cover surveillance, it have the advantage over a radar system in that it is "passive" and it will be undetectable. In essence the system is a dual system with the addition of an extra high magnification scope. Assume that the scopes are one meter apart and perfectly aligned/calibrated( parallel ) and have 1000 mm focal length. Assume that the cameras used in both scopes are identical and that the cameras CCD is 1/3" then the angular FOV for each scope will be 0.275º horizontally by 0.21º vertically. Assuming that the camera give standard definition video, high definition will provide better resolution, then we have a 640x480 frame size. Theoretically then the distance between two consecutive vertical lines of pixels will be in degrees: 0.275/640 = 0.00004296875º. Then the theoretical distance resolution using two of these setups one meter apart will be 133342.90 meters or about 130 kilometers, of course that theoretical maximal resolution will never be achieved, but by using highly quality mechanical construction and high resolution calibration procedures, with high quality cameras a close distance can be achieved. For a high definition CCD we have then a 1.38e-4 degree resolution between vertical pixel lines and the maximal distance estimation will be 412529.61 m or around 410km that is a little more than the distance to the International Space Station that is around 370km. All atmospheric objects will be in reach of this system. Now by the proved effectiveness of a dual optical system this triple system will be able to detect very small objects in the sky and by centering that object in the spotter FOV will be able to calculate the distance to that object. Knowing the distance to that object speed calculation is now easy. It is not difficult to imagine an extension of this system using a set of these triple systems covering with its FOVs all the visible sky in a fixed location. Then by software all these triple systems FOVs can be merged and a full sky view can be created where all the spotted objects are plotted with distance and speed for each object. This will be not different that the screen of a radar system, but it will be passive. Adding image intensifiers this system can work at night. Of course a cloudy sky will affect this system. There many ways that this idea can be improved: 1- Increasing the distance between the scopes/scope focal length/camera resolution will increase its maximal distance estimation. 2- By using a spotter camera capable of working in the far portion of the infrared spectrum will make its detection capabilities even greater and possible make the system work in medium cloudy/fog conditions. Another variation of this idea is to have a "cluster" of dual systems, physically close to each other that can cover all the visible sky at any given moment with their FOVs. Then to have two additional dual systems apart form the cluster of dual system and such that the three set of cluster and these two additional dual system forms a right angle with the cluster as vertices. Then these two additional dual systems can be used to get triangulations on each object spotted in each dual system of the cluster. That will be a little more difficult to implement but completely doable with current technology and software but a lot more precise and with far more distance coverage as that will be determined by the distance to the cluster of the two additional dual systems, the more apart that these two additional dual systems are from the cluster the more distant objects that can be triangulated.

Measuring In Astronomy--How Big How Far? (clip)
 
01:46
Many distances, like the distance around the earth, are impossible to measure directly. Yet almost 2,000 years ago, a man named Eratosthenes, was able to measure the size of the earth by using his knowledge of geometry. Today, surveyors use their knowledge of the properties of triangles to measure indirectly the distance between points on the earth's surface. The same method can be used to find the distance to nearby objects in space, by viewing the object from two different positions. If we know an object's distance, and how much of our field of view it takes up (its angular diameter) geometry also enables us to calculate the object's size.

The Earth is Not Alone - Space Documentary HD
 
01:55:45
Part 2: https://www.youtube.com/watch?v=bLlYCwYnM3k U.S. space agency NASA announced the discovery of more than 200 new planets on Monday, 10 of which are believed to be about the right size and temperature to support life. Of the 219 new suspected planets to have been discovered by NASA's Kepler telescope, 10 were found to exist in the so-called 'Goldilocks zone' of their solar system. This refers to the distance between the planet and their star, which is neither too hot nor too cold to support complex life. The presence of liquid water on these "rocky" Earth-like planets is seen as a key ingredient required for the existence of life. "Are we alone? Maybe Kepler today has told us indirectly, although we need confirmation, that we are probably not alone," Mario Perez, Kepler program scientist, said at a news conference. NASA launched the Kepler telescope in 2009 in a bid to discover whether other Earth-like planets are common or rare. The latest identification of suspected exoplanets – planets outside our own solar system – brings the tally discovered by the Kepler telescope to 4,034. The number of worlds thought to be approximately the same size and temperature as Earth is around 50.

View this webinar to learn more! Measuring soil moisture, detecting glacier movement, and evaluating geohazards are among the wide range of applications scientists have been developing in recent years for synthetic aperture radar (SAR) data. With the ability of radar to "see" through clouds and to image day/night in all seasons, scientists are increasingly recognizing radar as a valuable tool providing high-resolution, landscape-level data when optical sensors cannot. The NASA Alaska Satellite Facility Distributed Active Archive Center(DAAC) has 1.8 petabytes of processed radar data available at no cost to scientists, and radar format conversion software in place to facilitate use of the data by scientists working in a broad set of disciplines. This webinar highlights radar usage results across disciplines and different fields, explains radar basics, and explores the expanding role of radar data in research and applications ranging from archeology, to wildlife habitat monitoring, to civil engineering—and much more.

Freeman Dyson - The Lamb shift (64/157)

To listen to more of Freeman Dyson’s stories, go to the playlist: https://www.youtube.com/playlist?list=PLVV0r6CmEsFzDA6mtmKQEgWfcIu49J4nN American-British physicist and mathematician, Freeman Dyson, was born in England in 1923. Aged 25, he relocated to Cornell University and has become known for his achievements in the fields of solid state physics, nuclear engineering and quantum field theory. [Listener: Sam Schweber] TRANSCRIPT: One of the main reasons I came from England to America was because at the time when I made the decision all the good experiments were being done in America. I mean England was pretty barren as far as experimental physics was concerned, and then the main centre for the experimental work in America was Columbia. There was the physics department at Columbia; the leading spirit was Rabi who was a wonderful character and a great experimenter, and in Rabi's lab the decisive experiments were being done using the techniques of microwave spectroscopy that had been developed in World War II. So it was a spin-off essentially from the radar developments in World War II. All this microwave technology was available, and with microwaves you could observe very much finer details of atoms than you could before just with visible light. So, in particular, hydrogen, which is the thing that physicists love to play with, it is the simplest atom - you can do the spectrum of hydrogen with visible light, that had been done in the 1930s, and at that time they observed, there was a kind of suggestion, that things weren't quite right. The observed spectrum of hydrogen wasn't quite exactly what Dirac predicted it to be, but the difference was not quite clear because visible light isn't precise enough. But after the war when you had the microwave techniques you could measure the hydrogen spectrum really precisely, and that's what Lamb did. Willis Lamb, who was at Columbia working with Rabi, measured the hydrogen spectrum for the first time with really high precision with microwaves and he found this discrepancy between theory and experiment which is called the Lamb shift. Which was quite clear and definite with microwaves and you could measure it very accurately. So it became an outstanding problem for everybody to explain this. The hydrogen atom being the simplest and most deeply explored object in the whole universe, in a way - I mean if you don't understand the hydrogen atom, you don't understand anything, and to find that things were wrong even with a hydrogen atom was a big shock. So it became the ambition of every theoretical physicist to understand this. And basically that's why I came to America. I knew that's where the experiments were done, that's where I was likely to be able to really to get in touch with what was happening in the real world. And of course the people at Cornell were very closely in touch with the people in Columbia, and in particular Willis Lamb talked to Hans Bethe who was the professor at Cornell, and Bethe then sat down and gave the first more or less adequate theory of the Lamb shift, just from a physical point of view. He understood that the reason why you had the Lamb shift was that the electron in the hydrogen atom was interacting with the Maxwell electromagnetic field, in addition to interacting with the proton, so that the effect of the fluctuations in the Maxwell field were disturbing the electron while it was revolving around the proton, causing a slight change in the position of the orbits. And so it was the back reaction of the electromagnetic field on the electron that Lamb had been measuring. And so Bethe understood that from a physical point of view. The problem was then, could you actually calculate it? And with the quantum electrodynamics as it was then, it turned out you couldn't; that if you just applied the rules of the game as they were then understood and tried to calculate the Lamb shift, the answer came out infinity, not a number of megacycles but an infinite number of megacycles. So that wasn't very useful and so it was clearly a real defect of the theory that it couldn't grapple with this problem. And Hans Bethe in the spring of '47 succeeded in fudging it; by cutting off the Maxwell field at the high frequencies and considering only the low frequencies, he managed to get the right answer more or less. [SS] By doing mass renormalisation? Yes. He renormalised the mass, which means to say that he allowed for the fact that the measured mass of the electron already includes the back reaction of the Maxwell field, and so what you're comparing is not a bare electron and an interacting electron; you're comparing an interacting free electron with an interacting bound electron. So you have the interaction in both the bound and the free electron, so you're comparing the two states of an electron... Read the full transcript at http://www.webofstories.com/play/freeman.dyson/64

Sonic Tractor Beams Are Now A Reality - BTF
 
02:42
Behold The Future...Sonic Tractor Beams Are Now A Reality. People might still be annoyed that we don’t have warp drive yet, but another invention straight out of science-fiction has now become a reality. Researchers from the Universities of Bristol and Sussex, England in collaboration with Ultrahaptics have developed the first sonic tractor beam that can lift and move objects using nothing but sound waves. The team used a system made of 64 miniature loudspeakers able to create high-pitched and high-intensity sound waves, generating an acoustic hologram that can lift, move, rotate and hold small objects. The system can create three different shapes of acoustic force fields. The first was made to resemble tweezers, the second was a vortex-like structure which trapped the object in the middle, and the last one surrounds the object from all directions and keeps it in place. This new technology presents the opportunity for far-reaching applications: from mechanical support moving and assembling delicate objects, to medical aid where miniaturized beams could guide drugs through living tissue. Last year, scientists from the University of Dundee constructed a simple sonic tractor beam, but the newly developed technology gives the user a lot more control on the objects within the beam. Sriram Subramanian, Professor of Informatics at the University of Sussex and co-founder of Ultrahaptics, said in a statement: "In our device we manipulate objects in mid-air and seemingly defy gravity. Here we individually control dozens of loudspeakers to tell us an optimal solution to generate an acoustic hologram that can manipulate multiple objects in real-time without contact." An unprecedented ability to wield sound waves was necessary to reach this sophisticated technology. "We all know that sound waves can have a physical effect. But here we have managed to control the sound to a degree never previously achieved," added Bruce Drinkwater, Professor of Ultrasonics in the University of Bristol's Department of Mechanical Engineering. The current sonic tractor beam can levitate objects between 0.6 to 4 millimeters in size, and the maximum size for the levitated objects is determined by the frequency of the sound waves – the lower the frequency, the larger the object that can be manipulated. As sound frequencies can be easily changed, there's the potential of using sound at megahertz frequency, to move a cell, down to kilohertz, to lift a beach ball. "We have some future work on levitating a beach ball from 10 meters away but from my point of view, the really interesting applications are in manipulating small particles that are inside our body," lead author Asier Marzo told IFLScience. "That is possible because sound can travel through water or human tissue. This potentially enables the manipulation of clots, kidney stones, drug capsules, microsurgical instruments or cells inside our body without any incision." http://www.iflscience.com/sonic-tractor-beams-are-now-reality --------------------------------------------------------------------------------- Acoustic Holograms that Levitate Particles https://www.youtube.com/watch?v=g_EM1y4MKSc ---------------------------------------------------------------------------------------------------- Holographic acoustic elements for manipulation of levitated objects http://www.nature.com/ncomms/2015/151027/ncomms9661/full/ncomms9661.html
