Big picture, big data: Swiss unveil VR software of universe

Big picture, big data Swiss unveil VR software of universe

The final frontier has rarely seemed closer than this — at least virtually.

Researchers at one of Switzerland’s top universities are releasing open-source beta software on Tuesday that allows for virtual visits through the cosmos including up to the International Space Station, past the Moon, Saturn or exoplanets, over galaxies and well beyond.

The program — called Virtual Reality Universe Project, or VIRUP — pulls together what the researchers call the largest data set of the universe to create three-dimensional, panoramic visualizations of space.

Software engineers, astrophysicists and experimental museology experts at the Ecole Polytechnique Federale de Lausanne, or EPFL, have come together to concoct the virtual map that can be viewed through individual VR gear, immersion systems like panoramic cinema with 3D glasses, planetarium-like dome screens, or just on a PC for two-dimensional viewing.

“The novelty of this project was putting all the data set available into one framework, when you can see the universe at different scales — nearby us, around the Earth, around the solar system, at the Milky Way level, to see through the universe and time up to the beginning — what we call the Big Bang,” said Jean-Paul Kneib, director of EPFL’s astrophysics lab.

Think a sort of Google Earth — but for the universe. Computer algorithms churn up terabytes of data and produce images that can appear as close as one meter (about three feet), or almost infinitely far away — as if you sit back and look at the entire observable universe.

VIRUP is accessible to everyone for free — though it does require at least a computer and is best visualized with VR equipment or 3D capabilities. It aims to draw in a broad array of visitors, both scientists looking to visualize the data they continue to collect and a broad public seeking to explore the heavens virtually.

Still a work in progress, for now, the beta version can’t be run on a Mac computer. Downloading the software and content might seem onerous for the least-skilled computer users, and space — on a computer — will count. The broader-public version of the content is a reduced-size version that can be quantified in gigabytes, a sort of best-of highlights. Astronomy buffs with more PC memory might choose to download more.

The project assembles information from eight databases that count at least 4,500 known exoplanets, tens of millions of galaxies, hundreds of millions of space objects in all, and more than 1.5 billion light sources from the Milky Way alone. But when it comes to potential data, the sky is literally the limit: Future databases could include asteroids in our solar system or objects like nebulae and pulsars farther into the galaxy.

To be sure, VR games and representations already exist: Cosmos-gazing apps on tablets allow for mapping of the night sky, with zoom-in close-ups of heavenly bodies; software like SpaceEngine from Russia offers universe visuals; NASA has done some smaller VR scopes of space.

But the EPFL team says VIRUP goes much farther and wider: Data pulled from sources like the Sloan Digital Sky Survey in the United States, and European Space Agency’s Gaia mission to map the Milky Way and its Planck mission to observe the first light of the universe, all brought together in a one-stop-shop for the most extensive data sets yet around.

And there’s more to come: when the 14-country telescope project known as the Square Kilometer Array starts pulling down information, the data could be counted in the petabytes — that’s 1,000 terabytes or 1 million gigabytes.

Strap on the VR goggles, and it’s a trippy feeling seeing the Moon — seemingly the size of a giant beach ball and floating close enough to hold — as the horizon rotates from the sunny side to the dark side of the lunar surface.

Then speed out to beyond the solar system and swing by Saturn, then up above the Milky Way, swirling and flashing and heaving — with exoplanets highlighted in red. And much farther out still, imagine floating through small dots of light that represent galaxies as if the viewer is an unconscionably large giant floating in space.

“That is a very efficient way of visiting all the different scales that compose our universe, and that is completely unique,” says Yves Revaz, an EPFL astrophysicist. “A very important part of this project is that it’s a first step toward treating much larger data sets which are coming.”

Entire galaxies seem to be strung together by strands or filaments of light, almost like representation of neural connections, that link up clusters of light like galaxies. For one of the biggest pictures of all, there’s a colorful visualization of the Cosmic Microwave Background — the radiation left behind from the Big Bang.

“We actually started this project because I was working on a three-dimensional mapping project of the universe and was always a little frustrated with the 2D visualization on my screen, which wasn’t very meaningful,” said Kneib, in a nondescript lab building that houses a panoramic screen, a half-dome cinema with bean-bag seating, and a hard-floor space for virtual-reality excursions.

“It’s true that by showing the universe in 3D, by showing these filaments, by showing these clusters of galaxies which are large concentrations of matter, you really realize what the universe is,” he added.

What are the Ethical Issues in Biometrics?

Published

Ethical Issues in Biometrics

What is biometric identification? It is the process through which unique biological characteristics are used in biometric identification to recognize and validate a person. These characteristics can be found in facial traits, eye structures, DNA, fingerprint patterns, and even handwriting. All this data that can be gathered on an individual inevitably brings up the ethical issues in biometrics that need to be addressed.

Facial recognition and fingerprint scans were previously the domain of security, and they were utilized for identification and law enforcement. However, increasingly more business and civil applications are using biometrics authentication. Due to this increased use, it is crucial to address the moral and ethical issues in biometrics when used in the creation of new application and technology.

Applied biometrics and corporate ethics have received little empirical study despite the widespread use of biometric technologies. As a result, there is plenty of room for future study to help us better comprehend the moral consequences of adopting this technology.

This article examines the ethical concerns associated with the use of biometric technology on the use of biometrics for non-security applications as well as the moral ramifications for business.

Ethical Issues in Biometrics and Privacy

Biometric data takes privacy concerns to a whole new level that typical data gathering only touches on. Digital identities can be forged, and anonymity on the web can be maintained to a degree if you know how. Also, digital data can be deleted – if we forget that Meta (Facebook) has been revealed to store deleted data, which is an ethical concern in itself.

The problem with biometric data is that it is unforgeable, unconcealable, and permanent, You can’t change your eye structure, your fingerprint, or your facial features. Big tech companies already have your face, fingerprints, and your voice recorded and stored via current biometric authentication systems – mainly used for unlocking your phone. That data will be there forever, and there is little that people can do about it besides avoid it In the first place.

While many companies still give users the option of using a good old fashion passcode to unlock their phones, as technology as a whole tends to do, the biometric alternative is slowly gaining more traction, and will one day become the norm, as it is hard to argue its convenience and security. You can’t accidentally leave your eyeball at home or forget your fingerprint. But in the same sense, you can’t change it. If your childish curiosity while browsing the web put a black spot on your record, there’s no changing that.

Therein lies the question of who if anyone should have access to such data. Today’s tech giants have all our data in their hands, that won’t change with the spread of biometric verification methods. Indeed, it will only increase targeting capabilities.

While the collection of biometric data on its own does not necessarily mean it will be shared, monetized, or abused in any way, it never the less requires clear and strict guidelines and regulations to be implemented around it. There are too many things that can be abused by the wrong party when the ethical issues in biometrics are not taken seriously, and if such limitations are not applied stringently.

Electric Cars vs Gas Cars: How do They Compare Today

Published

 on

Electric Cars vs Gas Cars

Many prefer the rumbling ‘vroom’ of a gasoline car to the soft hum of an electric vehicle, while others would rather just be satisfied in the knowledge that they are lessening their carbon footprint. Let’s look at the cold hard facts however, and compare electric cars vs gas cars

Electric Cars vs Gas Cars: Components

The amount of moving components is an important distinction between electric and gasoline-powered automobiles. While a gasoline-powered car contains hundreds of moving components, an electric vehicle just has one, the motor. Another significant distinction is that the electric car has fewer moving components. The electric car is more dependable and needs less routine maintenance. The maintenance needed for a gasoline-powered car ranges from routine oil changes, filter replacements, tune-ups, and exhaust system repairs to less frequent component replacements including water and fuel pumps, alternators, and so on.

Electric Cars vs Gas Cars: Maintenance

The expenses associated with maintaining an electric car are reduced since there are less maintenance requirements. The shaft, the only moving component of the electric motor, is extremely dependable and needs little to no maintenance. The controller and charger are electrical devices that require minimal to no maintenance because they have no moving components. Modern sealed lead acid batteries are maintenance free and utilized in electric cars nowadays. However, these batteries have a finite lifespan and will eventually need to be replaced. New batteries are being developed to increase the range of electric cars as well as the battery pack’s lifespan, perhaps eliminating the need to replace the battery pack throughout the course of the vehicle’s lifespan.

Electric Cars vs Gas Cars: Efficiency

In addition to being simpler and less expensive to repair than gasoline-powered vehicles, electric vehicles are also more cost-effective to run. The electric car will drive roughly 43 miles for $1 based on the efficiency of 3 miles/kwhr and the cost of power at 7 cents per kwhr. The gasoline-powered car will go roughly 18 miles based on the average gas mileage of 22 miles per gallon and the price of gasoline at $1.25 per gallon. As a result, an electric car may drive more than twice as far on a dollar’s worth of petrol.

Where Electric Falls Behind

There are still a number of difficulties for the owner of an electric car despite the fact that it will be less expensive to operate and maintain.

The primary issue is the restricted range offered by existing battery technology. The amount of driving distance possible utilizing the current batteries is between 50 and 150 miles. These ranges are being extended by new battery technologies, and prototypes of these batteries have shown ranges of up to 200 miles between recharging. Solar powered charging stations are being implemented in numerous places to decrease range anxiety towards electric vehicles

The lack of qualified service professionals to repair and maintain electric cars is another issue that faces their owners. A two-year associate degree program has been developed to train high school graduates to become proficient electric vehicle technicians, and training programs are being developed and made available to upgrade the conventional automotive technician with the skills needed to maintain an electric vehicle.

Infrastructure to recharge the batteries is also required. The most important component of the infrastructure for recharging already exists: electric power is accessible practically everywhere. To support the electric car, it is still necessary to guarantee that charging stations with the right sorts of service (i.e., maximum voltage and current) are placed in important areas. Plans must also be made.
