How an advanced degree in business analytics can boost your career – WDIV ClickOnDetroit

As companies increasingly rely on data to drive strategic growth, there is a greater need, more than ever, for employees and leaders to be skilled at business analytics.

For example, according to the U.S. Bureau of Labor Statistics, a management analyst career is one of the fastest-growing, highest-paying positions in business, with projected growth greater than 14% from 2020 to 2030.

Whether you are in an entry-level position, a seasoned analytics professional, or you are looking to make a career change, a graduate degree in business analytics will better equip you to be competitive in this digital age.

As a Master of Science in Business Analytics (MSBA) student, you will develop analytical and leadership skills by learning how to use data to improve business decisions. You will also learn to deploy analytics to identify data insights that can be key to running a successful business.

MSBA graduates often go on to be self-employed or work in the professional, scientific, technical services, government, or finance and insurance industries. The Bureau of Labor Statistics reported in September 2021 that for those who go on to become management analysts*, the median pay is approximately $87,660, and the opportunities for new positions will grow to around 124,000 by 2030.

Below is a sampling of additional business analytics positions and their median annual salaries:

Business analyst, information technology: $70,489**

Business analytics director: $118,984***

Financial analysts: $83,660****

Operations research analysts: $86,200*****

For those who are eager to expand their knowledge and help shape the future of business, an investment in an analytics education can lead to a promising future.

A 2019 Deloitte Technology in the Mid-Market survey****** reported that 53% of corporate respondents said they are redesigning competency requirements to include skills like analytics and artificial intelligence. In the same report, more than 68% of respondents indicated they are developing new strategies to attract, recruit and retain workers in analytics-related positions.

Mining Parler and Mapping the Stop the Steal Campaign – Just Security

One of the biggest unresolved questions about the January 6th mob assault on the U.S. Capitol last year is how much social media factored into the violence that day. One year on, just over 700 people who answered Donald Trumps call to march on Congress are now facing charges in connection with the assault. Many of those indicted were identified through social media posts to Facebook, Twitter, and Parler, the far-right rival to mainstream platforms.

Facebook and Twitter have contended in the wake of the Capitol siege that their approach to content moderation is much more effective than so-called alternative tech, or alt-tech, platforms like Parler that brand themselves as champions of unmoderated free speech. But absent hard evidence and transparency about platform design features and about how content moderation decisions are made and implemented, it is hard to test those claims.

What we do know, one year on from January 6th, is that understanding how platform governance shapes the feedback loop between online social media and offline violence is crucial as we head toward the 2022 midterm elections. The urgency will only intensify if Trump runs for president again or otherwise involves himself in the 2024 election and succeeds in standing up his own social media company.

Recent polls indicate Americans are sharply divided about what happened on Jan. 6 and what it means for the future. But there is little question that the storming of the Capitol not only created a crisis of confidence in American democracy, but also shredded public faith in the tech industry. The attack on Congress and explosion of violent online content prompted Twitter and Facebook to ban Trump from their platforms, while Apple, Google, and Amazon all moved to cut off access to Parler.

Yet, there is a lot we still dont know about how social media factored into the calculations and decisions of the thousands of Americans who turned up in Washington on Jan. 6 to support Trump. How did niche social media sites geared toward far-right audiences, like Parler, contribute to polarization around the 2020 presidential election and factor into the January 6th attack? What trends can be extrapolated from the Parler data, and how might this data be used to detect early warning signs of political violence? Was Parler really more culpable, in important respects, than Facebook or Twitter in fanning the flames of the #StoptheSteal movement?

Millions of Users Sign Up

Founded in 2018, Parler took off during the 2020 presidential race. In the summer and fall of that year, high-profile conservatives, including representatives of the Trump campaign, urged their supporters to join them on Parler, which billed itself as a haven for free speech with a laissez-faire approach to moderation compared to mainstream platforms.

Millions of users signed up, driving a surge of activity leading up to and following the November election. In this environment, Stop the Steal the false narrative that Democrats had rigged the election in favor of Joe Biden spread like wildfire. Election conspiracy theories drove conversations on Parler to such an extent that posts mentioning Stop the Steal and overall Parler activity both peaked the week after Biden was projected to win the presidency, according an analysis of Parler data we conducted using the Social Media Analysis Toolkit.

In the immediate aftermath of the attack, Facebook chief operating officer Sheryl Sandberg tried to shift the blame for the violence onto Parler. The only way to test those claims, however, is to look at the data across platforms, and there is no shortage of that. On Jan. 11, 2021, an anonymous hacktivist who uses the handle @donk_enby on Twitter, released a massive tranche of Parler data that included 1,030,523 video posts and metadata from posts made by 13 million Parler users.

Working with our colleagues at Arizona State University and New Americas Future Frontlines program, we tapped into that data and other sources to assemble the puzzle pieces of what happened online and offline leading up to the January 6 siege. In addition to the @donk_enby video and image posts and metadata, another data source consisted of 183 million Parler posts collected by an international consortium of researchers, including several from New York University. Another data stream included charging documents for more than 630 individuals whom the FBI arrested and charged with crimes related to the Capitol breach, which traced arrestees to their state and town of residence. Yet another data set consisted of location information about protests that took place across the United States in the year leading up to the January 6th attack.

Nearly 60,000 of the 1 million-plus videos @donk_enby released contained latitude and longitude coordinates in the metadata, allowing us to map those videos to specific upload locations. The greatest density of video uploads was in the Washington, DC,region, with more than 1,000 in that area alone. The second most common location was St. Louis, Missouri, with over 500 video uploads.

Geographic Breadth

However, more than any particular location, what stands out about Parlers video content is its sheer geographic breadth. Parler users uploaded videos from many distinct locations across all 50 U.S. states, far too many to be the work of a centralized team. Many of the geotagged videos appear to be clustered around the suburbs and exurbs of major metropolitan areas. Rural areas are also well represented, particularly in more densely populated and privately owned rural areas east of the Rocky Mountains. By contrast, relatively few videos were uploaded near city centers.

Geographic diversity also increased over time. Parler users uploaded few videos to the platform before spring 2020, and until then, videos were sparsely distributed and varied in location from one month to the next. Only after the presidential campaign heated up in the summer of 2020, and video content spiked on Parler, does the data begin to show a trend toward consistent, diverse upload locations across the United States.

All this suggests Parlers successful penetration of grassroots political life in the second half of 2020. By November, the platform and Stop the Steal messaging, carried on the wings of politicians and influencers, had reached thousands of communities across the United States.

The list of Americans arrested and charged with crimes related to the January 6th Capitol attack confirms that Stop the Steal was a nationwide phenomenon. We mined charging documents and local news reports to find states and towns of residence for 632 individuals whom the FBI had arrested as of October 2021. The resulting dataset includes arrestees from 45 states and the District of Columbia. The top three states of origin were Florida (70), Texas (57), and Pennsylvania (56).

We wondered whether proximity to social unrest over the course of 2020 may have played some role in activating those who stormed the Capitol. So, we asked Princeton Universitys Bridging Divides Initiative to analyze arrestee residences against the U.S. Crisis Monitor, which records demonstrations and instances of political violence across the political spectrum.

The resulting analysis makes clear that the Stop the Steal movement gave geographic reach to Stop the Steal and suggests patterns of activation, such as proximity to protests. We found that the residences of those charged in the January 6th attack tended to cluster near areas where all types of demonstrations and counter protests took place, to a greater degree than anticipated under complete spatial randomness. In that respect, offline organized activity contributed to online activity, creating a potential feedback loop.

Patterns of Mobilization

We also learned that patterns of mobilization to violence on the platform were geographically distinct and evident well before the riot at the Capitol. Moreover, this relationship was strongest on the local rather than state level. That suggests that the proximity of protest activity prior to Jan. 6 may have been an influencing factor for a substantial number of those indicted in connection with the Capitol breach.

Understanding how protest activity near their homes may have influenced the Capitol rioters will require more research. Still, our work suggests that protest monitoring, combined with geotagged and anonymized social media content like that found in Parlers videos, may prove useful tools for detecting early warning signs of political violence from publicly available data. In other words, these types of findings may contribute to predictive models down the line.

Still, although the sheer volume of publicly available data from Parler is impressive and holds tremendous potential for modeling, it is important to note it does have limitations. It is impossible to collect complete data from most social media platforms, and the deplatforming of Parler means that the millions of posts we and other researchers have collected represent only a snapshot in time, and likely a highly pixelated one at that.

So-called alt-tech platforms in particular will be important to monitor and analyze as the 2022 midterm elections and 2024 presidential elections draw near. Our research, in fact, shows Parlers business model, platform design features, and content management system which gave outsized influence to high-profile Republican politicians like California Congressman Devin Nunes and pro-Trump personalities like Lin Wood combined to make the social media platform and its users especially vulnerable to high levels of manipulation and exposure to what Facebook and researchers refer to as coordinated inauthentic behavior.

Intimidating Content at a Large Scale

Coordinated inauthentic behavior may take any number of forms. In some cases, it might mean the use of bots to amplify content at a rapid rate, which can make memes and catchy hashtags like #StoptheSteal go viral. In other cases, as we saw with Russian interference in the 2016 presidential election, fake accounts can be used en masse to create a sense of ubiquity. It can also mean brigading that is, cooperating across networked social media to post intimidating content at such a large scale that it drowns out the voices of intended targets. Bottom line: what makes online behavior inauthentic is when posts are made at a rate and scale that would defy the laws of physics and human biology for a singular person.

Sometimes inauthentic behavior is deployed for deceptive reasons, as we saw with Russian interference in the 2016 and 2018 elections. Sometimes it is used to help spread important information faster and farther, as weve seen with important announcements about COVID precautions. The problem is that, when it is coordinated on a large scale, the overall impact is to create the illusion of virality. Or it can result in the misperception that content is trending and that sentiments are being widely validated in trusted networks of users and influencers. In both cases, it plays on cognitive biases that make us vulnerable to trickery and deception by machines.

Having a rough definition of inauthentic coordinated behavior and a sense of what it looks like on a platform like Parler isnt quite enough, however. The only way to know with any certainty about what the future impact of social media might be on Americas highly polarized politics is to examine how Parler users behaved before the platform was shut down and how the platform operated in a universe with giant supernovas like Twitter and Facebook shaping the very center of gravity on the Internet. Its also important to understand what, if any, connections exist between online and offline behavior.

What weve learned so far does not bode well for the future as we turn to the 2022 midterm elections. Given that Trump is launching his own social media platform, Truth Social, and that he may run for president again in 2024 or else try to shape the outcome, there are real reasons to worry about the proliferation of far-right alt-tech applications.

It has become commonplace in academia to call social media sites like Parler an echo chamber. But this term fails to capture the breadth and depth of the potential impact that lightly moderated platforms like Parler can have on political discourse and extremist violence. An echo chamber evokes an image of a bunch of words and memes bouncing around wildly inside a closed container. A more apt comparison for Parler and similar alt-tech sites is a hothouse: a place where conversations run wild, become radical, and eventually spill into the rest of the Internet and American political life.

The question for Congress, the White House, and the American public now is whether the United States can afford to let thousands or millions more poisonous hothouses bloom. If we want to prevent another January 6th, policymakers, researchers, and journalists likely need to keep a keen eye turned to Parler and the unwalled gardens where the alt-tech movement has taken root.

Bitcoin mining stocks halve as turbo-charged thesis plays out – The Block Crypto

Just as the price of bitcoin has steadily declined from highs of near $70,000 to around $42,000 today, so too have the share prices of the biggest crypto mining companies fallen.

But the decline of those mining stocks which experts believe represent a kind of turbo-charged proxy for the price of bitcoin has been even sharper than bitcoins. Several of the largest crypto miners have seen their share prices halve since the highs of November.

Based on The Block Researchs data, the market capitalization of Nevada-based Marathon Patent Group has dropped from $7.65 billion in early November to roughly $3 billion today. Colorados Riot Blockchain has fallen from $4.25 billion to $2.05 billion. And Toronto-based Hut 8 mining is down from $2.33 billion to $1.19 billion.

The share prices of Hive, Argo Blockchain and Canaan have also plummeted albeit less sharply than their larger rivals.

The performance of these stocks is hardly surprising given the headwinds that crypto miners have come up against in recent months. Authorities in China have become increasingly adept at snuffing out mining operations following a blanket ban, despite the evasive efforts of Chinas crypto miners.

Other countries have followed in Chinas footsteps. Only yesterday, Kosovo moved to outlaw crypto miningamid rolling blackouts enforced because of the countrys energy crisis. Tumult in Kazakhstan has also hindered bitcoin mining efforts.

Dilution is another key factor here. Crypto mining is a capital-intensive business and operators have been forced to raise significant amounts from public markets investors.

Analysis from The Block Research underscores the extent to which this constant need to raise money has diluted shareholders.

In the fourth quarter of last 2020, Marathon had 51,599,792 shares in circulation. By the fourth quarter of 2021, it had 102,630,637 shares a 98.9% increase. The story is similar for most of the big miners, as the table below shows.

But perhaps more relevant than these external factors in the decline of the bitcoin mining stocks is the simple fact that this is exactly how experts expected such stocks to behave.

In March last year, Ethan Vera, COO at Luxor Tech, described mining stocks as similar to a levered play on bitcoin.

The reason is that, beyond simply investing in and holding bitcoin, miners must invest heavily in infrastructure that will produce more bitcoin in the future.

Public mining stocks act as a high beta play to bitcoin price, so when the bitcoin price decreases the mining companies will feel extra pain, said Vera. Not only do most of them hold bitcoin as treasury, but their ASIC fleets [crypto mining machines] fluctuate in value with the price and are increasingly leveraged with USD denominated debt.

N.THING presents their up-to-date hybrid vertical farm at CES 2022 – PRNewswire

N.THING CUBE, a container-built vertical farm engineered to reduce using earth resources, enhances the production of clean and safe yields that are free from pollution and pesticides and cultivated in a sustainable environment. By saving energy, and creating a sustainable ecosystem, CUBE is elaborating a decentralized farming solution that can be set up in any city without relying on imports and logistics for easy access to a traceable food supply.

"So far, agricultural products have been produced in centralized protocols and due to its dependency on location and climate, it is managed in a centralized and grower-driven manner," says Leo Kim, CEO & founder of N.THING Inc.

The CUBE is fully managed by IoT, cloud computing, and stability data mining, and the OS and dashboard allows customers to grow crops professionally regardless of their agricultural experience. Overall, the OS governs the farm, and provides customers with full access to monitor in real-time. Relying on this software, N.THING also unveils their newest variety of crop 'hemp' at CES. As one of its solutions, hemp business can be secured more dependency and productivity relatively free from human elements and climate variations. By this distinctive strength, major deals have been offered on site to run PoC in the US and European market with leading players in this industry.

Currently, N.THING holds various partners from online, offline, and commerce players in Korea. N.THING generates revenues by selling crops, farms and solutions.The Korean partnerships include Emart, a leading retailer in Korea, and value chain partnerships, a major logistics center of the Emart covering Seoul and Kyungi area in South Korea, and is directly distributed to the Seoul and Kyungi branches, reducing footprint and food miles.

"More and more consumers globally are noticing why the locally produced vegetables are necessary. Our crops, which are distributed in the cold-chain system, are taking a few hours after harvest, as compared to days or weeks for average products."

The CUBE operating system aims to produce crops of the highest quality. Provided that the farm has been managed sustainably, the OS provides farm owners with an ability to cultivate quality crops, retrieve an estimate on the overall productivity and forecasted profits. The OS provides users with full control over the growing process, and is designed to add smart solutions that will impact the growth stages, unlike what is available with traditional farming.

"I look at vertical farming as the way forward of an opportunity to show how software can feed the world sustainably." Leo explained. "Ultimately, the end-goal is to achieve a consumer-driven market that means the food and crops can be produced what the consumers need on the time they need. And our operating system is designed to effectively achieve this."

N.THING's key concept, called FaaP, Farm as a Product, had won the Best of Innovation award at CES 2020, and received an honouree award at CES 2022 Innovation Awards for Sustainability, Eco-design and Smart energy. And now they are ready to open series C fundraising globally in 2022.

About N.THING:

Established in January 2014, N.THING is a Seoul-based Agri-Food tech company leading innovation in agricultural products, by extension, in the farm-to-table food value chain by combining IoT technology and data. It developed the world's first modular vertical farm 'CUBE' which is easy to expand. N.THING CUBE is a modularized farm with mass productivity where a dedicated OS provides the most optimized environment for each crop so as to create maximized efficiency. N.THING is the world's first smart farming company that won the iF Design Award, Architecture in 2020. Also, it is a winner of Best of Innovation at the CES 2020 for its excellence in technology, which is the first ever in the agricultural field.

Disinformation campaign against former MP Kenny Chiu a disturbing precedent, researchers say – The Globe and Mail

Conservative MP Kenny Chiu rises during Question Period in the House of Commons in Ottawa on April 13, 2021. The Conservative Party believes Mr. Chius defeat in the 2021 election was linked to a propaganda campaign against him.Adrian Wyld/The Canadian Press

Two researchers at McGill University say a disinformation campaign against a Conservative Party candidate during the 2021 election race is a disturbing demonstration of how propaganda tactics could be used by hostile foreign actors to interfere with Canadas political system.

And they suggest a countermeasure to discourage future disinformation efforts would be a public registry to track foreign influence that is similar to the very mechanism that former B.C. MP Kenny Chiu was attacked during the election campaign for proposing.

During the 2021 federal election campaign Mr. Chius proposal was condemned on Chinese-language social media, alleging his plan would suppress the Chinese community in Canada. The comments were disseminated on apps and websites widely used by some Canadians of Chinese origin, who make up approximately half of his ridings population.

What is alarming is these tactics could be deployed against any group in an information and psychological warfare campaign, the authors say. In short it has high potential for interference in Canadas electoral process by foreign state actors and thus severely threatens the countrys liberal democracy.

Writing this month in Policy Options, a publication of Canadas Institute for Research on Public Policy, Sze-Fung Lee and Benjamin Fung say Canada needs to better protect itself from disinformation campaigns that could damage this countrys electoral process. Ms. Lee and Mr. Fung are experts on information warfare. Ms. Lee is a research assistant in the School of Information Studies at Montreals McGill University, where Mr. Fung is a professor and Canada Research Chair in data mining for cybersecurity.

Mr. Chiu, a Canadian who was born in Hong Kong, was elected as the member of Parliament for the federal riding of Steveston-Richmond East in B.Cs Lower Mainland in 2019 but was defeated in the 2021 election. Data from the 2016 census indicate the ethnic origin of the ridings population is close to 50 per cent Chinese.

The Conservative Party believes Mr. Chius defeat was linked to the propaganda campaign against him, but foreign affairs critic Michael Chong acknowledges the evidence is so far inconclusive.

This disinformation effort against Mr. Chiu was recently documented by the Atlantic Council think tanks Digital Forensic Research Lab (DFRLab), in a November report.

DFRLab analyzed anonymous articles circulating on Chinese language apps and websites such as WeChat and Weibo, both heavily used by some Canadians of Chinese origin, that misrepresented a private members bill Mr. Chiu had tabled in 2021.

The Foreign Influence Registry Act he proposed was an effort inspired by similar Australian legislation to combat foreign interference that the Canadian Security Intelligence Service and other bodies have warned is a growing problem in Canada. It called for a registry where people working on behalf of foreign governments or corporations would have to file notice when they are trying to influence public policy, contracts or legislation in Canada. It exempted diplomats.

In late 2018, Australia enacted a Foreign Influence Transparency Scheme to track work being done by foreign governments and foreign state-owned enterprises as well as individuals or political organizations affiliated with countries. The United States Foreign Agents Registration Act (FARA) has been in effect since 1938 and a similar registry has been under consideration in Britain.

The election campaign attack on Mr. Chiu painted his registry proposal as an effort to target all people of Chinese origin in Canada. Once this act becomes law, all individuals or groups connected with China may be considered as spokespersons of the Chinese government and will be required to register specially, one article on WeChat alleged.

It said after this bill became law, activities related to associations in mainland China, as well as normal Sino-Canadian economic, cultural and technological exchanges, would be suppressed and have a profound negative impact on the Chinese community.

The anonymous attacks also called Mr. Chiu anti-China because he had been an outspoken critic of Beijings crackdown on dissent and protest in Hong Kong and because he had backed a motion condemning the Chinese governments repression in Xinjiang.

Ms. Lee and Mr. Fung said disinformation is widespread throughout social media in diaspora Chinese communities and that a language barrier sometimes prevents Chinese immigrants from verifying what they read by crosschecking it with other Western media.

They said its very difficult to prove who was behind the disinformation but say its logical to infer whoever was responsible for disseminating the fake news had a clear motive in reshaping the narratives in favour of Beijings interests.

The solution, the McGill academics say, is to expose the sources of influence on the public debate in Canada. They say a useful countermeasure would be a mechanism similar to what Mr. Chiu and the Conservative Party advocated, and which was proposed by Alliance Canada Hong Kong, an umbrella group of Canadian human-rights activists. This registry as outlined by the group would be paired with a public commission to enforce compliance with the registry.

Stars from ancient cluster found in the Milky Way – Ars Technica

Enlarge / Scientists have used the data from Gaia to track the location and motion of stars in our galaxy.

Galaxies like the Milky Way are thought to have been built through a series of mergers, drawing in smaller galaxies and clusters of stars and making these foreign stars their own. In some cases, the mergers were recent enough that we can still detect the formerly independent object as a cluster of stars orbiting the Milky Way together. But, as time goes on, interactions with the rest of the stars in the Milky Way will slowly disrupt any structures the cluster incorporates.

So it's a bit of a surprise that researchers found what appear to be the remains of a globular cluster composed of some of the oldest stars around. The finding is consistent with a "growth through merger" model of galaxy construction, but it raises questions about how the cluster stayed intact for as long as it did.

The results started with an analysis of data from the ESA's Gaia mission, which set out to do nothing less than map the Milky Way in three dimensions. Gaia imaged roughly a billion objects dozens of times, enough to estimate both their location and their motion around the Milky Way's core. This map has helped scientists identify structures within our galaxy based on the fact that there are some groups of stars that are not only physically close to each other, but all moving in the same direction.

The process of mining the Gaia data for these sorts of structures is so useful that there's a software algorithm called STREAMFINDER that identifies them. That software led to the discovery of the C-19 stellar stream, a group of stars moving together through the Milky Way's halo.

One way to check whether these groups of stars really started out as part of a single cluster is to check their age; clusters are often composed of stars with similar ages. One of the ways to see if stars formed at the same time is to check the content of heavier elements. There was little in the way of elements heavier than helium formed during the Big Bang, so most heavy elements that are now present were produced by earlier stars. The later in the history of the Universe a star formed, the more of these heavier elements that star is likely to contain.

(Astronomers call any element heavier than helium a metal and refer to a star's heavy-element content as its metallicity. But this will probably confuse most non-astronomers, so we'll avoid it.)

So, the astronomers behind the new work measured the levels of heavy elements in the stars that were thought to belong to the C-19 stream. And, with the exception of one outlier, they were all quite similar, suggesting that the stream really is the disrupted remnant of a cluster. But the results also contained a surprise: a remarkably low amount of heavy elements.

The typical way of registering heavy elements is through the ratio of iron (which is only formed late in the life of massive star) to hydrogen. Hydrogen has always been the most abundant element in the Universe, while iron levels have slowly built over time. So the higher the iron-to-hydrogen ratio, the more recently the star formed.

In the case of the C-19 stream, the ratio was extremely low. So low, that the stars of C-19 would have formed prior to 3 billion years after the Big Bang, or when the Universe was only about a quarter of its current age. And they likely formed quite a bit earlier than that.

Within the Milky Way, a few hundred stars have been identified with similarly low heavy-element levels. But no cluster in which every star has such a low level has ever been seen. In fact, prior to this discovery, clusters in the Milky Way were thought to have a heavy-element floorall of them had levels above those seen in the C-19 stream. This was true despite the fact that, based on the distribution of known clusters, we'd expect about five with heavy-element levels similar to that of the C-19 stream.

The lack of other clusters suggests that most of the earliest clusters like this stream have already been disrupted to the point that they've faded into the background of Milky Way stars. Which raises the question of why the C-19 stream hasn't. That's especially unexpected given that the stream's orbit around the galactic core takes it deep inside the Milky Way, giving it plenty of chances to engage in interactions with other features that should disrupt it.

One possibility that could explain this is that the cluster originally entered the Milky Way as part of a dwarf galaxy that was swallowed. The dwarf galaxy's structure could provide a degree of protection until it became disrupted and its stars spread through the Milky Way. And, if this were true, then the cluster that gave rise to the C-19 stream would have had a large fraction of the stars present in the dwarf galaxy at the time.

Regardless of how it ends up being explained, the presence of the C-19 stream tells us things about the history of the Universe. "The very existence of C-19 proves that globular clusters must have been able to form in the lowest-metallicity environments as the first galactic structures were assembling," the researchers conclude.

Polish chess player falls off chair after humiliating defeat. His reaction to viral video is the winning move – The Indian Express

Chess is not an active sport and needs a lot of restraint and mental prowess. However, Polish national player Pawel Teclaf added a lot of action to it as he swung and accidentally fell off a chair after facing a humiliating defeat.

The 18-year-old player lost his championship to Tigran Petrosian, 37, from Armenia at the FIDE World Blitz Championship in Warsaw, held on December 29.

In the fast-moving match, playing white, Teclaf lost after his opponent made his winning move. Realising that he made a blunder, Teclaf threw himself back in his chair. The chair lost balance and Teclaf tumbled on the floor.

Petrosian lent a helping hand, but Teclaf had hit the floor already. Immediately, Teclaf sprung up and shook hands with Petrosian, hiding his humiliation.

Watch the video here:

I usually swing on my chair because I just like it, and that was the first time I just fell down, Teclaf said as quoted by Dailymail. Then I stood up fast. Everything was fine, it was just the moment, he added.

We had a maximum of ten seconds left on the clock in a time scramble. I was gradually spoiling my position until I was unable to set a fortress, and then I even managed to screw it up, he said as quoted by Mirror.

The clip shared on YouTube channel Anti-Chess24 left netizens in splits. Petrosians stoic reaction is fantastic. What brilliant self control! commented a user.

After the video did rounds on social media, Teclaf realised he was getting popular. In the morning, I was in the elevator & a person standing next to me was staring at me and on her phone back and forth, smirking. When I go to my room, I opened WhatsApp and saw plenty of links and realised I am getting popular, International Chess Federation tweeted as said by Teclaf.

The video has garnered over 2 lakh views so far.
