Its all in the data – The Hindu

May 10, 2021 | Author: admin

Data has become an increasingly important resource. Business organisations are using data-driven insights to not just understand their customers and improve services but also to increase efficiency of their processes and enhance overall performance.

However, there is more to data than its application in businesses. It can be stored, categorised, analysed and used to predict future trends across various sectors, including education. Not only can data help improve the education sector, it can also make learning a social-emotional concept.

While the pandemic forced the education system move online, e-learning is currently limited to a few digital platforms. While teachers and learners have adjusted to this model, the former lack a few key insights such as attendance, students individual performance, strengths and weaknesses and so on. Including data science in education can help both the teachers and the students.

Learning analytics will allow educators to gather the learners performance data to leverage lesson outcomes. Apart from the attention aspect, it will also help in setting test and exam benchmarks. With the use of effective tools such as multi-source knowledge mapping and predictive analysis, it is possible to design a system that caters to individual learning needs and a more comprehensive evaluation.

Traditionally, instructors have relied on assessments and periodic tests to judge the students progress. This often resulted in late identification of struggling individuals. However, with the use of data science, the data of every student is stored, filtered, and correlated to specific metrics such as learning success. Teachers not only get to know attendance details but also interest areas, learning pace, difficult topics and, ultimately, attentiveness of each student.

As patterns emerge, instructors can make changes to help struggling learners. Early warning signs can help teachers reach out to students and offer interventions. Further, data analytics makes it possible to track every students activity to understand where they are most and least engaged. Based on this, teachers can create personalised learning plans to move away from one-size-fits-all paradigm. A feedback system is thus created to help instructors to discover solutions to the most common problems in online learning.

With the strong and growing demand for social-emotional learning, the education system must prioritise the development and assessment of social-emotional competencies. A data-informed approach will help educators invest in strategies that help reach this end.

The use of data science in education can help make learning better and more effective and improve the quality and impact of the teaching methodology.

File-sharing 101: How to actually share files in Google Drive and OneDrive – CNET

May 10, 2021 | Author: admin

Sharing files on Google Drive or OneDrive isn't hard.

Need to share a big file, or photos or videos that won't fit in an email? Never fear. It's easy to send almost anything to co-workers, family members and friends online -- and often for free.

Enter two of the most popular options for sharing files, photos and videos: Google Drive and Microsoft OneDrive. Here, we'll walk you through how to choose which cloud file sharing service is best for you, how much it costs to use, and how to actually share files with others. (Make sure you check out our comparison of the best cloud storage services of 2021, too.)

Learn smart gadget and internet tips and tricks with our entertaining and ingenious how-tos.

Which file sharing service you want to use likely depends on whose ecosystem you're already in: Google Workspace (formerly called G Suite) or Microsoft 365. If your workplace is governing which you use, you probably don't have a choice. But if you're looking to sign up for personal use, you might want to know a bit about each service.

If you use any of Google's productivity apps (Gmail, Docs or Calendar, for example), using Google Drive makes sense. With Drive, you get 15GB of free storage for anything you upload, including photos, videos and documents. Those who need more space can sign up for Google's storage subscription service, Google One. Google One plans start at $2 a month in the US for 100GB of storage and other features, like Google Store discounts.

If you use Outlook or Windows 10 (which you can still download for free) and are used to Microsoft's ecosystem, OneDrive might be the better choice for you. Microsoft 365 subscribers (who also have access to apps like Word and Excel) have 1TB of storage available. Non-subscribers can sign up for OneDrive Basic for free, which gets you 5GB of storage. Or, similar to Google One's base tier, the OneDrive Standalone plan costs $2 a month for 100GB of storage.

Both Google Drive and OneDrive are compatible with Android and iOS, as well as Windows and MacOS desktops.

Google Drive gives you 15GB of free storage -- but you need to share it between all of your Google accounts.

Using Google Drive? Here's how to share files step by step:

1. On your computer, go to drive.google.com.

2. Right-click on the folder or file you want to share.

3. If you want to share with people or groups, click Share. Enter their email addresses in the Add people and groups field. On the next screen, you'll see that they are set to Editor as a default, which means they can make changes to the file or add photos. You can click the drop down and change them to Commenter or Viewer. Add a message if you want, and click Send. The people you share it with will get an email with a link to the file or folder.

4. If you want to get a shareable link that you can send to a person or group, right-click on the folder or file, and click Get link (you'll also see this if you click Share, at the bottom of the window). The default setting is Restricted, which means only people you've shared the file with in the step above can open the link. If you click that, you can change it to Anyone, which means anyone with the link can open it. If you choose Anyone, you can then decide if you'd like those people to be able to edit, comment or view the file from the dropdown. Click copy link.

Alternately, you can open any file and click Share in the top right corner to see these options.

The free OneDrive Basic plan gives you 5GB of storage.

If you're using OneDrive, here's how to share files:

1. Go to the OneDrive website, and sign in with your Microsoft account (or your work or school account).

2. Select the file or folder you want to share by clicking the circle in the upper corner of the item. You can also pick multiple items to share them together (though you can't do this on work or school accounts).

3. At the top of the page, click Share.

4. Enter the email addresses or groups you'd like to share with. Click the pencil icon next to this field, and choose if you want those you share with to be able to edit, or just to view the file. Add a message if you want to, and click Send. The people you share it with will get an email with a link to the file or folder.

5. If you'd rather get a link for sharing, click Share, and click the top box, which says People you specify can edit. You can change this setting to anyone with the link, anyone in your organization, people with existing access or specific people. Under Other settings, you can uncheck the allow editing box, which means people you share with can view, copy or download the file without making changes. Click Apply. Then, click Copy to copy the link.

Alternately, you can open any file and click Share in the top left corner to see these options.

Physicist and jazz pianist combines music and science at Rochester – University of Rochester

May 9, 2021 | Author: admin

May 6, 2021

As an undergraduate and later graduate student at the University of Rochester, Philippe Lewalle 14, 21 (PhD) has played piano at the Colleges music and physics department commencement ceremonies.

This year will be different, though: he will also be the one graduatingwith a PhD in physicsduring spring commencement ceremonies, May 14 to 16 and 20 to 23.

Visit the Class of 2021 site for details about this years Commencement ceremonies and for a downloadable toolkit of materials to share your support on social media.

The child of parents who are both violinists and academics, Lewalle began playing piano at age 7 and was drawn to Rochester because the University offered the possibility to combine his love of music and interest in science, earning dual degrees in music and physics at the School of Arts & Sciences.

I came to Rochester in large part because it was feasible to double major in physics and music, he says. Even though I was working a lot of long days as an undergrad, it always felt refreshing having two very different types of homework on my platter. If I got tired of one, I could always switch to the other.

The summer after his sophomore year, Lewalle had the opportunity to work with Joseph Eberly, the Andrew Carnegie Professor of Physics, conducting research on quantum optics. The research would ultimately set the direction of his graduate work and PhD dissertation.

That summer definitely shaped the trajectory I took later, Lewalle says. The research I conducted as an undergrad ended up relating a lot to my PhD work.

As a graduate student, he worked with physics professor Andrew Jordan, where his specific research focus was on tracking quantum systems in real timea process that is intrinsically invasive to changing the system state itself as it is monitoredand the odd things that happen when such systems are disturbed. The research is important not only for better understanding fundamental quantum mechanics, but also for improving quantum technologies such as quantum computers.

Throughout his time at Rochester, Lewalle continued to play music with a variety of musicians at venues in the city and took advantage of the musical opportunities offered by the Rochester community.

The pool of talent that comes through Eastman is really motivating and inspiring, Lewalle says. I have benefited a lot from playing with so many talented musicians throughout my time here, in addition to attending a number of the great performances, whether at Jazz Fest, student recitals, or other concerts that are held on a regular basis at Eastman and venues around the city.

Lewalles own musical interests include contemporary jazz and its intersections with hip-hop and free improvisation. One project he played in, called Claude Benningtons Fever Dream, involved a synthesis of hip-hop and jazz that took a jazz rhythm section and instead of horn players, put rappers out front, he says. We were learning beats and treating them like jazz tunes, improvising on and around them and sometimes venturing freely away from the written material. Recordings from the project are available on Bandcamp and YouTube.

Although many of his music projects have stalled due to the COVID-19 pandemic, Lewalle has continued to work on his own compositions and record and play when possible and safe, even while finishing his physics PhD thesis.

Its been difficult during COVID because, especially with jazz improv, you really feed on the energy of the crowds and the immediate interactions between musicians, he says. Its not the same without that.

In July, Lewalle will start a new chapter as he travels across the country to California to begin a postdoctoral research appointment, studying quantum mechanics in the group of K. Birgitta Whaley at the University of California Berkeley.

Are We on the Brink of a New Age of Scientific Discovery? – SciTechDaily

In 2001 at the Brookhaven National Laboratory in Upton, New York, a facility used for research in nuclear and high-energy physics, scientists experimenting with a subatomic particle called a muon encountered something unexpected.

To explain the fundamental physical forces at work in the universe and to predict the results of high-energy particle experiments like those conducted at Brookhaven, Fermilab in Illinois, and at CERNs Large Hadron Collider in Geneva, Switzerland, physicists rely on the decades-old theory called the Standard Model, which should explain the precise behavior of muons when they are fired through an intense magnetic field created in a superconducting magnetic storage ring. When the muon in the Brookhaven experiment reacted in a way that differed from their predictions, researchers realized they were on the brink of a discovery that could change sciences understanding of how the universe works.

Earlier this month, after a decades-long effort that involved building more powerful sensors and improving researchers capacity to process 120 terabytes of data (the equivalent of 16 million digital photographs every week), a team of scientists at Fermilab announced the first results of an experiment called Muon g-2 that suggests the Brookhaven find was no fluke and that science is on the brink of an unprecedented discovery.

UVA physics professor Dinko Poani has been involved in the Muon g-2 experiment for the better part of two decades, and UVA Today spoke with him to learn more about what it means.

Q. What are the findings of the Brookhaven and Fermilab Muon g-2 experiments, and why are they important?

A. So, in the Brookhaven experiment, they did several measurements with positiveand negative muons an unstable, more massive cousin of the electron under different circumstances, and whenthey averaged their measurements,they quantified a magnetic anomaly that is characteristic of the muon more precisely than ever before. According torelativistic quantum mechanics, the strength of the muons magnetic moment (a property it shares with a compass needle or a bar magnet) should be two in appropriate dimensionless units, the same as for an electron. The Standard Model states, however, that its not two, its a little bit bigger, and that difference is the magnetic anomaly. The anomaly reflects the coupling of the muon to pretty much all other particles that exist in nature. How is this possible?

The answer is that space itself is not empty; what we think of as a vacuum contains the possibility of the creation of elementary particles, given enough energy. In fact, these potential particles are impatient and are virtually excited, sparking in space for unimaginably short moments in time. And as fleeting as it is, this sparking is sensed by a muon, and it subtly affects the muons properties. Thus, the muon magnetic anomaly provides a sensitive probe of the subatomic contents of the vacuum.

To the enormous frustration of all the practicing physicists of my generation and younger, the Standard Model has been maddeningly impervious to challenges. We know there are things that must exist outside of it because it cannot describe everything that we know about the universe and its evolution. For example, it does not explain the prevalence of matter over antimatter in the universe, and it doesnt say anything about dark matter or many other things, so we know its incomplete. And weve tried very hard to understand what these things might be, but we havent found anything concrete yet.

So, with this experiment, were challenging the Standard Model with increasing levels of precision. If the Standard Model is correct, we should observe an effect that is completely consistent with the model because it includes all the possible particles that are thought to be present in nature, but if we see a different value for this magnetic anomaly, it signifies that theres actually something else. And thats what were looking for: this something else.

This experiment tells us that were on the verge of a discovery.

Q. What part have you been able to play in the experiment?

A. I became a member of this collaboration when we had just started planning for the follow-up to the Brookhaven experiment around 2005, just a couple of years after the Brookhaven experiment finished, and we were looking at the possibility of doing a more precise measurements at Brookhaven. Eventually that idea was abandoned, as it turned out that we could do a much better job at Fermilab, which had better beams, more intense muons and better conditions for experiment.

So, we proposed that around 2010, and it was approved and funded by U.S. and international funding agencies. An important part was funded by a National Science Foundation Major Research Instrumentation grant that was awarded to a consortium of four universities, and UVA was one of them. We were developing a portion of the instrumentation for the detection of positrons that emerge in decays of positive muons. We finished that work, and it was successful, so my group switched focus to the precise measurements of the magnetic field in the storage ring at Fermilab, a critical part of quantifying the muon magnetic anomaly. My UVA faculty colleague Stefan Baessler has also been working on this problem, and several UVA students and postdocs have been active on the project over the years.

Q. Fermilab has announced that these are just the first results of the experiment. What still needs to happen before well know what this discovery means?

A. It depends on how the results of our analysis of the yet-unanalyzed run segments turn out. The analysis of the first run took about three years. The run was completed in 2018, but I think now that we weve ironed out some of the issues in the analysis, it might go a bit faster. So, in about two years it would not be unreasonable to have the next result, which would be quite a bit more precise because it combines runs two and three. Then there will be another run, and we will probably finish taking data in another two years or so. The precise end of measurements is still somewhat uncertain, but I would say that about five years from now, maybe sooner, we should have a very clear picture.

Q. What kind of impact could these experiments have on our everyday lives?

A. One way is in pushing specific technologies to the extreme in solving different aspects of measurement to get the level of precision we need. The impact would likely come in fields like physics, industry and medicine. There will be technical spinoffs, or at least improvements in techniques, but which specific ones will come out of this, its difficult to predict. Usually, we push companies to make products that we need that they wouldnt otherwise make, and then a new field opens up for them in terms of applications for those products, and thats what often happens. The World Wide Web was invented, for example, because researchers like us needed to be able to exchange information in an efficient way across great distances, around the world, really, and thats how we have, well, web browsers, Zoom, Amazon and all these types of things today.

The other way we benefit is by educating young scientists some of whom will continue in the scientific and academic careers like myself but others will go on to different fields of endeavor in society. They will bring with them an expertise in very high-level techniques of measurement and analysis that arent normally found in many fields.

And then, finally, another outcome is intellectual betterment. One outcome of this work will be to help us better understand the universe we live in.

Q. Could we see more discoveries like this in the near future?

A. Yes, there is a whole class of experiments besides this one that look at highly precise tests of the Standard Model in a number of ways. Im always reminded of the old adage that if you lose your keys in the street late at night, you are first going to look for them under the street lamp, and thats what were doing. So everywhere theres a streetlight, were looking. This is one of those places and there are several others, well, I would say dozens of others, if you also include searches that are going on for subatomic particles like axions, dark matter candidates, exotic processes like double beta decay, and those kinds of things. One of these days, new things will be found.

We know that the Standard Model is incomplete. Its not wrong, insofar as it goes, but there are things outside of it that it does not incorporate, and we will find them.
