Antimatter just passed the gravity test

Particle physicists at CERN in Switzerland have found the answer to one of the great mysteries of physics: How does antimatter fall?

It’s the first-ever observation of free-falling antimatter, which proved that atoms of antihydrogen are pulled downward due to gravity, as their matter equivalents.

Wait. What’s anti-hydrogen?

Well, that’s a positron orbiting an antiproton. Positrons are positively charged electrons and antiprotons are basically negatively charged protons.

To understand all that sub-atomic phenomenon, we need to take a quick trip to the exotic and explosive world of antimatter.    

We learned at school that everything we see around us is made up of matter. All matter consists of atoms, which in turn, consist of protons, neutrons and electrons.

Antimatter is matter’s evil twin. Its particles share the same mass as their matter counterparts, but qualities such as their electric charge are opposite. And this makes it explosive. When any matter comes into contact with antimatter, they annihilate each other, releasing all the energy stored inside them.

Remember the antimatter explosion scene of Dan Brown’s Angels and Demons – when a little bit of the stuff blew up over Vatican City? The science depicted in the movie is based on fact.

It doesn’t sound like antimatter can be real, but it does exist in the universe. The good news is that there is not much antimatter to be found around our planet to annihilate our existence.

However, physicists at CERN have been making it at the Antimatter Factory for some time now, to study this elusive and most expensive substance on Earth.  

[One gram of antimatter may cost about $62.5 trillion, that’s around ₹5,000 billion]


So, what’s new?

Particle physicists found that antihydrogen atoms, released from the magnetic confinement in CERN’s ALPHA-g apparatus, behave consistent with gravitational attraction to the Earth.

The successful experiment will now allow precision analysis of the magnitude of gravitational acceleration between anti-atoms and the Earth, to test the weak equivalence principle of the general theory of relativity.

It has taken us 30 years to learn how to make this anti-atom, to hold on to it, and to control it well enough that we could actually drop it in a way that it would be sensitive to the force of gravity. The next step is to measure the acceleration as precisely as we can,” says Jeffrey Hangst, ALPHA researcher & spokesperson, CERN

This ‘proof-of-principle experiment’ by ALPHA researchers at CERN is a confirmation of Einstein’s general theory of relativity, which postulates that all masses, irrespective of differences in their internal structures, react to gravity in a similar manner. 

CERN’s Antimatter Factory is a unique facility in the world for producing and studying antimatter. The experiments at this facility are aimed at measuring with high precision the gravitational acceleration of atomic antimatter.

Thematic funds – Performance tracing with a narrative

Sure you have come across the terms sectoral fund and thematic fund, often used loosely by investors. But they are not the same. While a sectoral fund invests in a particular industry sector, thematic fund can invest in diverse sectors around a particular opportunity or a business ‘theme’. 

A thematic fund is an equity mutual fund that invests in stocks around a theme that could be infrastructure, commodity, rural India, international etc.

They tend to be attractive to retail as well as institutional investors, who often call it ‘performance tracing with a narrative’. These funds come with a great story and a bunch of stocks that generate impressive returns.


Investment approach

Consider this: A fund manager or an asset management company (AMC) identifies growth potential or consumption boost in a particular theme, say opportunities in real estate/housing. The AMC may launch, say, a ‘Housing Opportunities Fund’ that will invest in a range of sectors like housing finance, consumer electronics, cement, banks, steel, power and more.   

A thematic fund can invest across different sectors and market caps (large cap, mid cap, small cap) as long as it conforms to the housing theme. The minimum investment in equity and equity-related instruments of a particular theme should be 80% of the asset under management (AUM), mandates SEBI. 

Thematic funds use a top-down investment approach. For a particular theme, the asset manager first takes a broad view of the economy and markets, including global trends. If there is enough opportunity, the asset manager or AMC begins to investigate related sectors and individual stocks to invest.


Common thematic funds

1. IT or Digital Funds

2. Pharma Funds

3. MNC Funds

4. PSU Funds

5. Dividend Yielding Funds

6. Infrastructure Funds


Advantages

Thematic funds are all the rage, ever since the pandemic ebbed and the markets returned to high growth path. Recent news reports indicate returns of thematic funds, such as public sector undertaking (PSU), infrastructure, consumption and information technology fared well, compared to the large-cap fund category in the past one year. Analysts say, these funds are cyclical in nature and have given higher returns during the period.

High returns for each ‘theme’ have respective opportunity factors. For example, attractive valuation and hope for privatisation have led to major rerating in PSU stocks. The government’s infrastructure push has led to a rally in the sector. The technology sector, despite corrections, continued to remain one of the top performers in the past few years. Growth opportunities, as such, make thematic funds attractive to long-term investors.

Thematic funds also have some inherent advantages compared to sectoral funds and mutual funds that follow conventional investment strategies. As we already know now, a thematic fund is more diversified than a sectoral fund, having its investments diversified in several sectors and not just in one.

Most importantly, it offers an investor the opportunity to invest in theme-related sectors that have a high growth potential.


 Here’s more:

>Since thematic funds invest in stocks and sectors that are closely related in their business scope, the fund is more focused and easy to track

>Since thematic funds carry a high degree of risk, they are likely to deliver high capital appreciation in the long-term

>Since certain themes like information technology (IT), robotics, EVs, renewable energy and the sunrise sector projects significant growth potential, retail investors can take the advantage of early investment. One can increase allocation in these industries/themes by taking higher exposure in relevant themes if convinced with the improving environment for the industry.


Disadvantages

>Thematic funds are more volatile and riskier than the conventional equity funds

>Portfolio diversification is an essential part of effective investment strategy. But thematic investments can make investors put too many eggs in one basket and lose sight of portfolio diversification

>Thematic opportunities, if misinterpreted by the fund managers (who are caught up in their idea of what will be the next big trend), can lead to losses

>Yes, a lot depends on the tactical approach of fund managers. Best returns from thematic investment depend on the fund managers’ market timing. Unless stocks are bought low and sold high, thematic investment cannot offer the expected results

>Often performance-chasing by retail investors is negative for thematic funds. This is because most of the time when investors enter certain theme, valuations have already peaked and the fund has turned expensive

>Most retail investors lack the knowledge, research capability and temperament to sustain the volatility associated with thematic investments. As such, analysts suggest that novice retail investors should avoid thematic funds and stick to vanilla diversified funds

>The more exotic a fund gets, costs tend to rise, because things may not be competitive in those niches. So, an investor ends up paying more expense ratios.

Digital marketing: Driving sales while sailing through turbulence

As the world today is pushed into extended lockdown and social distancing to combat the Covid-19 pandemic, digital media has assumed a central position in the marketing mix of companies. While companies today are not new to the digital space, digital marketing is the most effective tool at the moment to garner brand recognition, customer attention and support online sales when brick-and-mortar touchpoints are shut. It has now moved beyond handling a few sales channels to connect marketing to the business goals of a company. As the internet became integral to our lives, here’s how digital marketing has proved to be helpful for a range of businesses:

 

Retail and supermarket chains

Despite the surge in e-commerce, according to an estimate, in-store sale accounted for 90 per cent of all retail sales in the US in 2017. But it all changed with Covid-19 pushing traditional stores and marketing efforts out of the picture.

Retail giants have redesigned their product catalog for online-only sales while also working with hyper-local delivery services to stay cost-efficient and cut down on delivery turn-around time. Their mobile apps are updated quickly to interact with customers virtually as well as driving sales. The applications include product information, launch announcement, real-time status of delivery and more. 

For example, in the absence of brick-and-mortar stores, Indian retail giants Big Bazaar and Spencer stuck to their omnichannel marketing during the pandemic to ensure an effortless buying experience for consumers. Others added grocery delivery to their service and leveraged insight from the Pandora’s Box of their consumer data to deliver a personalised shopping experience online.

 

Food delivery service

With people stuck indoors, food delivery services have witnessed a surge like never before. Since restaurants and food-courts are not an option anymore, people are turning to delivery to treat themselves at home. On-demand food delivery services like UberEats in the USA and Swiggy in India have been using the social media platforms to reach out to customers about new offerings, reduced delivery turn-around time and contactless delivery options.

Others in this category are also leveraging the prospects of emerging cloud kitchen businesses with digital advertising and interactive content to monetise their last-mile reach.

When it comes to digital campaigns, it’s possibly the best time to tell a story with an emotional trigger. Indian food delivery service Zomato celebrated Mother’s Day amid the lockdown this year with a digital campaign focused on mothers who dedicate so much time cooking delicious food for their kids. It was aimed to strike a chord with customers by emphasising on realisation of a mother’s love for her children with #OrderForMom.


Ed-tech

Akin to food-tech companies, ed-tech majors also witnessed a significant increase in the number of new students enrolling on their platforms since March 2020 — students are now more dependent on online learning than ever before.  

Ed-tech players like BYJU’S, Unacademy, UpGrad in India know what the Gen-Z and their parents want and tweaked their digital marketing strategy on this two-pronged approach. Not surprisingly, their digital campaigns, social media marketing and market research paid off better than other intrusive channels (like SMS and emails) to expand the student base.

As most schools and universities are likely to be closed for the remainder of the academic year, the new-age platforms are allowing students to take up from a range of courses like university-certified MBA to diploma programs at a competitive cost. In fact, most ed-tech players are now offering free access to their platforms, content and live classes for students as a part of their user acquisition strategy.

 

Healthcare

Be it a solo practice, small clinic or a multi-specialty chain, services are the product for healthcare players. But a responsive website, Google Adwords campaigns and SEO tactics may not be adequate during an uncertain time like this. Healthcare companies and start-ups are turning to social media to share professional knowledge regarding healthcare — the aim is to attract customers, build trust and drive awareness as a part of their digital marketing strategy.    

Beyond localised organic marketing (SEO), players in the healthcare industry are also using their Covid-capabilities as lead generators for other specialised service lines, create digital access-points for elective procedures and specialty care, as well as catering to the increasing demand for online medical content. Multi-channel initiatives like engaging with chatbots can be preferable to some customers, while others may choose Twitter or Facebook page to interact with the brand. Digital marketing tools like information blogs, educative video contents and interactive touch-points for customers can also overshadow traditional marketing in these uncertain times.

All that’s fake on the internet


Fake news is just the tip of the iceberg. The truth is, the internet is full of lies and you need a keen eye to segregate the bogus from the bona fide

Job offers
Fraudulent job emails usually don’t have detailed information about the role, company and package. Also, if an offer asks you to pay for an appointment or interview, it’s fake. No employer asks for money in the name of security deposits in advance.

Social profiles
Social media influencers often grumble about fake profiles. But they are not difficult to identify — a fake profile will have a stock image or no image, not many friends, lack of activity in the platform and too many or too few followers. Then there are bot accounts that are fake voters with loud opinions or obsessive re-tweeters.

Products
Do you know one among four products in your shopping wishlist at an e-commerce site can be counterfeit? Irrespective of what you intend to buy, compare the product with the one listed on the brand’s official website, and look for the assurance tag on the product to ensure it’s genuine. Also, avoid products offering heavy discounts.

Reviews
Fake reviews are nothing new on hotel, restaurant, book and e-commerce sites. But they can be damaging. Unlike genuine reviews that contain words specifically relating to the place or product in question, the fake ones are vague and include repeated use of same words or marketing terms. Questionable grammar and the use of superlatives are also signs of suspicious reviews. 

Apps
Fake mobile apps mimic the look of legitimate applications to trick you to install them. Once installed, they tend to perform malicious actions. Such apps are usually hosted on third-party app stores. If you come across apps in the App Store and Play Store that are crowded with ads, then stay away. You should also check all app permissions carefully.

Scareware
Unlike malware or spyware, scareware pretends to be real security protection and then tricks you into paying to clean up infections it claims to have detected. To avoid falling into the trap, install a decent anti-virus, avoid visiting dubious web locations, and if a fake ransom demand popup refuses to leave your screen, call its bluff by killing the browser using Task Manager.  

Emails
We are all introduced to fake or phishing emails where the sender is ‘fishing’ for our personal information. And they are not difficult to identify as well — just ‘report spam’ if you receive an email with impersonal greetings like ‘Dear user’ or ‘Dear [your email address]’, or if the email asks you to click on links that take you to a fake website, contains unknown attachments or conveys a false sense of urgency.

Online surveys
The internet has hundreds of legitimate survey sites. Then there are the fake ones that invite people to take surveys. If a site offers outrageous incentives such as free vacations, expensive products or a lot of cash, it’s fake. Stay away from platforms that ask for your family or bank details or asks you to download software. And never share your frequently used email IDs.
