China’s “Sky Eye” telescope makes a major breakthrough in terms of gravitational waves

Researchers in China have just made a breakthrough in nanohertz gravitational waves, which might be a gateway to understanding supermassive black holes in the universe. Let’s take a look at this interesting discovery.

What are nanohertz gravitational waves?

Gravitational waves are ripples in space-time created when massive objects like planets and stars move at very high speeds. And these waves travel at the speed of light, 1.86 miles per second There’s a wide spectrum of gravitational waves and those with extremely low frequencies are nanohertz gravitational waves. These are created by extremely large but slow-moving objects like black holes.

And the only way to study gravitational waves is either using radio telescopes or a technique called “Pulsar timing array“. Breakthrough in nanohertz gravitational wave research might unlock secrets to the formation, evolution, and merger of galaxies, and the early structure of the universe.

CPTA Nanohertz Gravitational Waves - Visualization

Recently, researchers from the Chinese Pulsar Timing Array (CPTA) used the “Sky Eye” FAST telescope (located in Guizhou, China) and found key evidence of nanohertz gravitational waves.

CPTA Findings

Researchers at CPTA used Five-hundred-meter Aperture Spherical Telescope (FAST) to analyze data from 57 millisecond pulsars, spanning 41 months. The analysis of the collected data hinted at “very encouraging” evidence of nanohertz gravitational waves. This will possibly allow scientists to systematically study supermassive black holes orbiting each other at the core of galaxies. 

“Our statistical confidence level is 4.6 sigma, which means the chances for the signal to be caused by some noise rather than gravitational waves are lower than two in a million,” said Kejia Lee, team leader of the operation.

He also added that they were currently unable to identify the astronomical sources of current signals due to the short observation span but will be able to do so as the time spans increase.

International efforts

CPTA achieved its breakthroughs at the same time as other international agencies like NANOGrav from the US. And PPTA from Australia, EPTA from Europe, and InPTA from India. Findings from all these institutions will be shared under the International Pulsar Timing Array (IPTA). But as of today, CPTA has not signed the data-sharing agreement yet. 

So right now, China is at the forefront of nanohertz gravitational wave research but the findings are still not concrete. CPTA’s accuracy of 4.6 sigma — while impressive  — falls just short of the 5 sigma gold standard required to claim the detection of these waves. So, for the time being, looks like we’re still far from unlocking the secrets to the mysteries of black holes.

Your iPhone is secretly tracking you — and here’s how you can disable it

Did you know that our devices and services track our every move? In today’s digital age, it’s no longer a secret that they actually do. Our privacy is not a thing now. From our online activities to our physical locations, everything is tracked. One major example of this is our smartphones, particularly iPhones. These devices have a feature called “Significant Locations,” which keeps a record of everywhere we’ve been.

Significant Locations in iPhones:

How to access the feature?

If you’re curious about finding out the location tracking feature, you can do it in a few easy steps:

  1. First, open your iPhone’s settings and go through the “Privacy & Security” section.
  2. From there, select “Location Services” and scroll down to find “System Services.”
  3. Tap on “Significant Locations” and give your face id or passcode to view a list of the places you’ve visited.

You might notice that some locations aren’t accurate, and it is because of a flaw in tracking.

If you want to see the details of your tracking, tap on the specific location in the list, and a map will show where the phone thought you were. However, your internet should be active in order to track your location.

Can you turn Significant Locations off?

Yes, of course. If you find this tracking uncomfortable, you have the option to clear your Significant Locations history. Simply go back to the “Significant Locations” menu and tap on “Clear History.” This action will remove all your Significant Locations data from any devices linked to the same Apple ID.

If you wish to disable Significant Locations altogether, go to the same menu and slide the toggle next to it to the left. This will turn off the feature and prevent your iPhone from tracking your whereabouts.

Why does Apple track your location data?

Our privacy concern for potential misuse remains questionable, but according to companies, features like Significant Features exist to provide personalized services and improve user experiences. When I say “companies,” I mean Apple, Google, and Meta. However, such companies assure users that the transmitted data is encrypted. These data are only accessible if someone has both their phone and password.

In today’s world, it is rare to have digital privacy. But we do have a little control over the tracking features on our devices. By following the simple steps outlined above, we can access and manage the location tracking on our iPhones. The feature is similar in Google Maps as well. Thus, it is quite essential to stay informed and take necessary steps to protect our privacy in this interconnected world.

Beyond Reality: A Comparative Guide to AR, VR & MR

Today’s technological advancements have led to the development of new ways to interact with the world around us, blurring the lines between the real and the virtual. As a result, Augmented Reality (AR), Virtual Reality (VR), and Mixed Reality (MR) have gained significant attention due to their potential to reshape industries and enhance user experiences. Although these terms are often used interchangeably, they are different from one another. So, in this article, we will explore the concepts of AR, VR, & MR, highlighting their unique features, applications, and potential impact on our lives to better understand what they offer to the table.

VR (Virtual Reality)

Virtual Reality (VR) takes users into digital environments, disconnecting them from the real world. In VR, individuals can explore computer-generated worlds that mimic reality or are completely unrealistic. It utilizes special headsets, motion-tracking technology, and handheld controllers to make users feel like they’re really there and can interact with the virtual components. The entertainment industry uses VR for gaming and storytelling, allowing players to become their characters and feel fully engaged. Moreover, VR has applications in education, training, healthcare, and more beyond entertainment.

Virtual-Reality-VR

There are some challenges that need to be addressed before VR can become truly mainstream. These challenges include:

  • Cost: VR stimulating components are expensive, limiting their affordability to a few users.
  • Content: Not all multimedia can be streamed through VR, limiting the engaging experiences that can be achieved with this technology.
  • Motion sickness: Some people experience motion sickness when using VR headsets. This is a problem that needs to be addressed before VR can be used for extended periods of time.

AR (Augmented Reality)

Augmented Reality (AR) is a technology that augments what we perceive in the real world with digital elements, making it more fascinating and participatory. AR seamlessly incorporates digital material into the actual environment, from basic applications like virtual filters on social media sites to more intricate usage in disciplines like architecture. It has the potential to revolutionize the shopping experience by allowing shoppers to try on virtual items or perceive things in their real environment. Furthermore, AR-based navigation systems can deliver real-time instructions and information, improving our ability to navigate cities and discover new areas.

Augmented-Reality-AR

Here are some things to keep in mind when dealing with the AR components:

  • Power consumption: AR can be power-intensive, which can limit the amount of time that AR can be used.
  • Accuracy: AR relies on the accuracy of the tracking system to coincide with digital content in the real world. If the tracking system is not accurate, the AR content will not provide appealing results.
  • Latency: AR requires real-time tracking and rendering of digital content. If there is a delay in showing the virtual content in AR right away, it can interrupt the smooth experience and make it feel strange to users.
  • Privacy concerns: AR components have to track users’ movements and activities, which raises privacy concerns.

You might want to read these:

MR (Mixed Reality)

MR combines the best of AR and VR to create a hybrid experience that mixes the digital and real worlds flawlessly. Users can engage with virtual things that are merged into their real-world surroundings with this technology. Architects, for example, may use MR to see and modify 3D models of structures while being connected to the actual world. This technology has significant implications for remote work, enabling collaboration and innovation regardless of geographical barriers.

Mixed-Reality-MR

The challenges that the MR comes with:

  • Software development: MR software is still in its early stages of development. This can make it difficult to find high-quality MR applications, and it can also be difficult to develop new MR applications.
  • User experience: MR can be a very immersive experience, but it can also be disorienting. This can make it difficult for users to interact with MR applications in a natural way.
  • Performance: MR headsets can be computationally demanding. This means that they need to be powerful enough to render the virtual world and track the user’s movements in real time.

Differences between AR, MR, and VR

    This app by former Google engineer can calculate food calorie just from photos

    Have you ever shared your beautifully presented meals on social media? At least a snap on Snapchat? Well, a new smartphone application called SnapCalorie now has a genuine reason to take food pictures. Developed by former engineers from Google and defense contractor Raytheon, SnapCalorie claims to count calories in any meal simply by analyzing a photo. Surprised? The app is already available for free download on both App Store and Google Play, with an option for a premium subscription costing $29.00 per month.

    SnapCalorie Overview:

    The creators of the application say that SnapCalorie is actually better than professional nutritionists at estimating calorie content. They argue that human beings are not much good at visually estimating the portion sizes of food, and their app can provide more accurate calorie counts. They also expect dieters who are cautious about their calorie intake in each meal to accept and use this app.

    How is the nutrition data calculated?

    SnapCalorie’s impressive accuracy is credited to a unique dataset called Nutrition5k which was developed by the company itself. They collected nutritional data from 5,000 popular real-world meals and paired it with thousands of photos and videos of those meals, which were captured using a robotic rig. Further, They used the extensive dataset to train a computer vision algorithm. It accurately estimated the caloric content of various dishes, including challenging ingredients like oils and sauces.

    SnapCalorie’s co-founder, Wade Norris, previously worked on Google’s Google Lens project. The project used computer vision to extract information about objects in the real world. With SnapCalorie, Norris aimed to use this technology to directly improve people’s lives by providing accurate calorie information.

    Accuracy and Error Rate

    The team also claimed that the combined error rate for calories, food mass, and macronutrient mass on average is 16.5%. However, if we compare the average error rate of calorie count done by a professional nutritionist, it is 41%. Furthermore, ordinary individuals had an even higher rate of 53%.

    The app enhances its accuracy not only by utilizing the unique capabilities of modern phone cameras, such as depth sensors, but also by employing a team of expert human reviewers who ensure an additional layer of quality in measuring portion sizes.

    Competitors and Future Success

    There are many other calorie-counting apps based on AI, like Lose It, Foodadviser, Bite.AI, and Calorie Mama. But, according to the app’s founder, the differentiating factor for SnapCalorie from its competitors is accuracy. There are previous studies results showing disappointing results for some existing apps, with Calorie Mama being correct only 63% of the time.

    SnapCalorie has already received $2 million in investments from notable sources like Index Ventures, Y Combinator, and CrossFit CEO Eric Roza. Now, the company’s future success will depend on its ability to improve and maintain its accuracy in the market.

    Subscription Fees

    SnapCalorie’s premium subscription model is currently priced at $29.00 per month, with an annual option available at $149.00. Users expect continuous improvement in the app’s AI-generated calorie estimations over time.

    In conclusion, SnapCalorie is really an innovative approach to calorie count with just a click. With the help of its well-researched dataset and advanced computer vision algorithms, the app aims to provide accurate calorie estimates. It does surpass the capabilities of professional nutritionists, but the challenges and competition in the market still question its effectiveness.
